(PLoS, 2019) López Sáez de Asteasu, Mikel; Martínez Velilla, Nicolás; Zambom Ferraresi, Fabrício; Casas Herrero, Álvaro; Lusa Cadore, Eduardo; Galbete Jiménez, Arkaitz; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua
Background: Acute illness requiring hospitalization frequently is a sentinel event leading to long-term disability in older people. Prolonged bed rest increases the risk of developing cognitive impairment and dementia in acutely hospitalized older adults. Exercise protocols applied during acute hospitalization can prevent functional decline in older patients, but exercise benefits on specific cognitive domains have not been previously investigated. We aimed to assess the effects of a multicomponent exercise intervention for cognitive function in older adults during acute hospitalization. Methods and findings: We performed a secondary analysis of a single-blind randomized clinical trial (RCT) conducted from February 1, 2015, to August 30, 2017 in an Acute Care of the Elderly (ACE) unit in a tertiary public hospital in Navarre (Spain). 370 hospitalized patients (aged ≥75 years) were randomly allocated to an exercise intervention (n = 185) or a control (n = 185) group (usual care). The intervention consisted of a multicomponent exercise training program performed during 5–7 consecutive days (2 sessions/day). The usual care group received habitual hospital care, which included physical rehabilitation when needed. The main outcomes were change in executive function from baseline to discharge, assessed with the dual-task (i.e., verbal and arithmetic) Gait Velocity Test (GVT) and the Trail Making Test Part A (TMT-A). Changes in the Mini Mental State Examination (MMSE) test and verbal fluency ability were also measured after the intervention period. The physical exercise program provided significant benefits over usual care. At discharge, the exercise group showed a mean increase of 0.1 m/s (95% confidence interval [CI], 0.07, 0.13; p < 0.001) in the verbal GVT and 0.1 m/s (95% CI, 0.08, 0.13; p < 0.001) in the arithmetic GVT over usual care group. There was an apparent improvement in the intervention group also in the TMT-A score (−31.1 seconds; 95% CI, −49.5, −12.7 versus −3.13 seconds; 95% CI, −16.3, 10.2 in the control group; p < 0.001) and the MMSE score (2.10 points; 95% CI, 1.75, 2.46 versus 0.27 points; 95% CI, −0.08, 0.63; p < 0.001). Significant benefits were also observed in the exercise group for the verbal fluency test (mean 2.16 words; 95% CI, 1.56, 2.74; p < 0.001) over the usual care group. The main limitations of the study were patients’ difficulty in completing all the tasks at both hospital admission and discharge (e.g., 25% of older patients were unable to complete the arithmetic GVT, and 47% could not complete the TMT-A), and only old patients with relatively good functional capacity at preadmission (i.e., Barthel Index score ≥60 points) were included in the study. Conclusions: An individualized, multicomponent exercise training program may be an effective therapy for improving cognitive function (i.e., executive function and verbal fluency domains) in very old patients during acute hospitalization. These findings support the need for a shift from the traditional (bedrest-based) hospitalization to one that recognizes the important role of maintaining functional capacity and cognitive function in older adults, key components of intrinsic capacity.

(Elsevier, 2024-09-27) López Sáez de Asteasu, Mikel; Martínez Velilla, Nicolás; Ramírez Vélez, Robinson; Zambom Ferraresi, Fabrício; Galbete Jiménez, Arkaitz; Lusa Cadore, Eduardo; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Estadística, Informática y Matemáticas; Estatistika, Informatika eta Matematika; Gobierno de Navarra / Nafarroako Gobernua, 2186/2014
Background. Sex-based differences in the clinical presentation and outcomes are well-established in patients hospitalized for geriatric syndromes. We aimed to investigate sex differences in response to in-hospital exercise on function, strength, cognition, and quality of life in acute care admissions. Methods. 570 patients (mean age 87 years, 298 females [52.3%]) admitted to acute care for elderly units were randomized to multicomponent exercise emphasizing progressive resistance training or usual care. Functional assessments included Short Physical Performance Battery (SPPB), grip strength, Mini-Mental State Examination (MMSE), and health-related quality of life (EQ-VAS). Results. Exercising females showed more significant SPPB improvements than males (between-group difference 1.48 points, p = 0.027), exceeding the minimal clinically significant difference. While female participants significantly increased handgrip strength and male patients improved cognition after in-hospital exercise compared to the control group (all p < 0.001), no sex differences occurred. Conclusions. Females demonstrate more excellent physical function improvements compared to male older patients. Findings highlight the importance of tailored exercise incorporating patient factors like biological sex in geriatric medicine. Trial registration. NCT04600453

(Wiley, 2020) López Sáez de Asteasu, Mikel; Martínez Velilla, Nicolás; Zambom Ferraresi, Fabrício; Ramírez Vélez, Robinson; García Hermoso, Antonio; Lusa Cadore, Eduardo; Casas Herrero, Álvaro; Galbete Jiménez, Arkaitz; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Background: A classic consequence of short-term bed rest in older adults is the significant loss in skeletal muscle mass and muscle strength that underlies the accelerated physical performance deficits. Structured exercise programmes applied during acute hospitalization can prevent muscle function deterioration. Methods: A single-blind randomized clinical trial conducted in an acute care for elders unit in a tertiary public hospital in Navarre (Spain). Three hundred seventy hospitalized patients [56.5% female patients; mean age (standard deviation) 87.3 (4.9) years] were randomly allocated to an exercise intervention (n = 185) or a control (n = 185) group (usual care). The intervention consisted of a multicomponent exercise training programme performed during 5–7 consecutive days (2 sessions/day). The usual-care group received habitual hospital care, which included physical rehabilitation when needed. The main endpoints were change in maximal dynamic strength (i.e. leg-press, chest-press, and knee extension exercises) and maximal isometric knee extensors and hip flexors strength from baseline to discharge. Changes in muscle power output at submaximal and maximal loads were also measured after the intervention. Results: The physical exercise programme provided significant benefits over usual care. At discharge, the exercise group showed a mean increase of 19.6 kg [95% confidence interval (CI), 16.0, 23.2; P < 0.001] on the one-repetition maximum (1RM) in the leg-press exercise, 5.7 kg (95% CI, 4.7, 6.8; P < 0.001) on the 1RM in the chest-press exercise, and 9.4 kg (95% CI, 7.3, 11.5; P < 0.001) on the 1RM in the knee extension exercise over usual-care group. There were improvements in the intervention group also in the isometric maximal knee extension strength [14.8 Newtons (N); 95% CI, 11.2, 18.5 vs. −7.8 N; 95% CI, −11.0, −3.5 in the control group; P < 0.001] and the hip flexion strength (13.6 N; 95% CI, 10.7, 16.5 vs. −7.2 N; 95% CI, −10.1, −4.3; P < 0.001). Significant benefits were also observed in the exercise group for the muscle power output at submaximal loads (i.e. 30% 1RM, 45% 1RM, 60% 1RM, and 75% 1RM; all P < 0.001) over usual-care group. Conclusions: An individualized, multicomponent exercise training programme, with special emphasis on muscle power training, proved to be an effective therapy for improving muscle power output of lower limbs at submaximal loads and maximal muscle strength in older patients during acute hospitalization.

Chronic effects of different intensities of power training on neuromuscular parameters in older people: a systematic review with meta-analysis
(Springer, 2023) Guimarães, Marcelo Bandeira; Blanco‑Rambo, Eduarda; Vieira, Alexandra Ferreira; López Sáez de Asteasu, Mikel; Pinto, Ronei Silveira; Izquierdo Redín, Mikel; Lusa Cadore, Eduardo; Ciencias de la Salud; Osasun Zientziak
Background Power training (PT) has been shown to be an efective method for improving muscle function, includ‑ ing maximal strength, measured by one-repetition maximum (1RM), and power output in older adults. However, it is not clear how PT intensity, expressed as a percentage of 1RM, afects the magnitude of these changes. The aim of this systematic review (International prospective register of systematic reviews—PROSPERO—registration: CRD42022369874) was to summarize the evidence from randomized clinical trials (RCT) assessing the efects of lowintensity (≤49% of 1RM) and moderate-intensity (50–69% of 1RM) versus high-intensity (≥70% of 1RM) PT on maximal power output and maximal strength in older adults. Methods We included RCTs that examined the efects of diferent intensities of power training on maximum strength and power output in older people. The search was performed using PubMed, LILACS, Embase, and Scopus. Methodological quality was assessed using the preferred reporting items for systematic reviews and meta-analyses (PRISMA 2020 statement checklist), and the quality of evidence was determined using the PEDro scale. Data were analyzed using standardized mean diferences (SMD) with a 95% confdence interval (CI), and random efects models were used for calculations. A signifcance level of p≤0.05 was accepted. Results Three RCTs assessing 179 participants, all of high methodological quality, were included. There were no sig‑ nifcant diferences between diferent PT intensities in terms of power output gains for leg press [SMD=0.130 (95% CI −0.19, 0.45), p=0.425] and knee extension exercises [SMD: 0.016 (95% CI −0.362, 0.395), p=0.932], as well as leg press 1RM increases [SMD: 0.296 (95% CI −0.03, 0.62); p=0.072]. However, high-intensity PT (70–80% of 1RM) was sig‑ nifcantly more efective than low-intensity PT in increasing 1RM for knee extension exercise [SMD: 0.523 (95% CI 0.14, 1.91), p=0.008]. Conclusions PT performed at low-to-moderate intensities induces similar power gains compared to high-inten‑ sity PT (70–80% of 1RM) in older adults. Nonetheless, the infuence of PT intensity on lower-limb strength gains seems to be dependent on the assessed exercise. Cautious interpretation is warranted considering the inclusion of only three studies.

The chronic effects of low- and high-intensity resistance training on muscular fitness in adolescents
(Public Library of Science, 2016) Assunção, Ari R.; Bottaro, Martim; Ferreira Junior, João B.; Izquierdo Redín, Mikel; Lusa Cadore, Eduardo; Gentil, Paulo; Ciencias de la Salud; Osasun Zientziak
To compare the effects of high-load, low-repetition maximum (LRM) and low-load, high-repetition maximum (HRM) resistance training regimens on muscular fitness in untrained adolescents. Forty-five untrained adolescents of both sexes (13.7±0.8 years; 161.3±7.5 cm, 56.8±13.4 kg) were randomly assigned into one of three groups: 1) LRM (n = 17): volunteers performed three sets of 4-6-repetition maximum (RM); 2) HRM (n = 16): volunteers performed three sets of 12–15 RM; and 3) control (CON, n = 12). Training was performed two times a week for 9 weeks. After training, there were significant increases in 1 RM chest press (LRM = 14.8%and HRM = 14.2%, p<0.05) and squat (LRM = 26.4%and HRM = 25.7%, p<0.05), with no differences between the LRM and HRM groups (p>0.05). Additionally, muscular endurance increased significantly for the chest press (LRM = 14.5% and HRM = 21.8%, p<0.05) and squat test (LRM = 31.4% and HRM = 32.4%, p<0.05) following resistance training, with no difference between the LRM and HRM groups (p>0.05). These results suggest that both high-load, low-repetition and moderate-load, high-repetition resistance training can be prescribed to improve muscular fitness in untrained adolescents.

Compartimentalización neuromuscular de los músculos vastus medialis y abductor digiti minimi en personas jóvenes
(2021) Guzmán Venegas, Rodrigo Antonio; Izquierdo Redín, Mikel; Lusa Cadore, Eduardo; Alonso Martínez, Alicia; Ciencias de la Salud; Osasun Zientziak
Existe evidencia de que el reclutamiento de unidades motoras dentro de un mismo músculo presenta cierta heterogeneidad. Esta heterogeneidad en la activación de las unidades motoras ha llevado a la hipótesis de que ciertos músculos podrían organizarse neuromuscularmente como compartimentos funcionales, más allá de la existencia demostrable de estos a nivel morfológico. Esto implicaría que las unidades motoras agrupada en determinadas regiones musculares tendrían diferentes niveles de activación que unidades motoras ubicadas en otras zonas del mismo músculo. Varios estudios han evidenciado la existencia del reclutamiento diferencial de los músculos del tronco y las extremidades, demostrando la existencia de una compartimentación funcional. Esta tesis buscó demostrar la existencia de una compartimentación funcional en los músculos Vasto Medial y Abductor Digiti Minimi en personas jóvenes.

Construct validity and test-retest reliability of the International Fitness Scale (IFIS) in Colombian children and adolescents aged 9-17.9 years: the FUPRECOL study
(PeerJ, 2017) Ramírez Vélez, Robinson; Cruz Salazar, Sandra Milena; Martínez, Myriam; Lusa Cadore, Eduardo; Alonso Martínez, Alicia; Correa Bautista, Jorge Enrique; Izquierdo Redín, Mikel; Ortega, Francisco B.; García Hermoso, Antonio; Ciencias de la Salud; Osasun Zientziak
Background: there is a lack of instruments and studies written in Spanish evaluating physical fitness, impeding the determination of the current status of this important health indicator in the Latin population, especially in Colombia. The aim of the study was two-fold: to examine the validity of the International Fitness Scale (IFIS) with a population-based sample of schoolchildren from Bogota, Colombia and to examine the reliability of the IFIS with children and adolescents from Engativa, Colombia. Methods: the sample comprised 1,873 Colombian youths (54.5% girls) aged 9–17.9 years. We measured their adiposity markers (waist-to-height ratio, skinfold thickness, percentage of body fat and body mass index), blood pressure, lipids profile, fasting glucose, and physical fitness level (self-reported and measured). A validated cardiometabolic risk index score was also used. An age- and sex-matched subsample of 229 schoolchildren who were not originally included in the sample completed the IFIS twice for reliability purposes. Results: our data suggest that both measured and self-reported overall physical fitness levels were inversely associated with percentage of body fat indicators and the cardiometabolic risk index score. Overall, schoolchildren who self-reported “good” or “very good” fitness had better measured fitness levels than those who reported “very poor/poor” fitness (all p < 0.001). The test-retest reliability of the IFIS items was also good, with an average weighted kappa of 0.811. Discussion: our findings suggest that self-reported fitness, as assessed by the IFIS, is a valid, reliable, and health-related measure. Furthermore, it can be a good alternative for future use in large studies with Latin schoolchildren from Colombia.

Dose-response relationship between exercise duration and enhanced function and cognition in acutely hospitalized older adults: a secondary analysis of a randomized clinical Trial
(Oxford University Press, 2024-06-01) López Sáez de Asteasu, Mikel; Martínez Velilla, Nicolás; Zambom Ferraresi, Fabrício; Galbete Jiménez, Arkaitz; Ramírez Vélez, Robinson; Lusa Cadore, Eduardo; Abizanda, Pedro; Gómez-Pavón, Javier; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Estadística, Informática y Matemáticas; Estatistika, Informatika eta Matematika; Institute of Smart Cities - ISC; Gobierno de Navarra / Nafarroako Gobernua
Background and objectives: exercise may reverse functional decline in hospitalized older adults, but the optimal duration is unclear. This study examined the potential relationship between in-hospital multicomponent exercise program duration and changes in physical function, cognition, and muscle function to maximize exercise-related health benefits in acutely hospitalized older patients. Research design and methods: this secondary analysis of a multicenter randomized controlled trial examined the relationship between the duration of an in-hospital multicomponent exercise program and changes in physical function, cognition, and muscle strength in 570 acutely hospitalized older adults. Participants completed 3, 4, or 5-7 consecutive days of exercise based on the progression of their acute medical illness. The acute clinical condition of the older patients was similar across the study groups (i.e., 3/4/5-7 days) at admission. Outcomes included the Short Physical Performance Battery (SPPB) for functional capacity, Gait Velocity Test for gait speed, handgrip for muscle strength, and cognitive tests. Results: of the 570 patients included in the analysis, 298 were women (52.3%), and the mean (SD) age was 87.3 (4.8) years. Exercise groups increased SPPB scores compared with controls, with gains of 1.09 points after three days, 1.97 points after four days, and 2.02 points after 5-7 days (p < .001). The 4-day program showed the most significant benefit for functional capacity. Gait velocity increased by 0.11 m/s after 4 and 5-7 days (p = .032). Similar dose-response relationships were seen for handgrip strength and cognition, with 5-7 days showing more significant gains than three days (p < .05). Discussion and implications: multicomponent exercise programs enhance physical and cognitive function in hospitalized older adults, regardless of exercise dosage. A 4-day program significantly boosts functional capacity, although 5-7 days improves handgrip strength and cognition, highlighting the importance of exercise dosage in countering functional decline. Implementing evidence-based inpatient exercise prescriptions can help reverse muscle weakness and improve cognitive and physical function.

Efectos del ejercicio físico en ancianos frágiles institucionalizados
(2024) Bays Moneo, Ana Beatriz; Izquierdo Redín, Mikel; Lusa Cadore, Eduardo; Ciencias de la Salud; Osasun Zientziak
Los programas de ejercicio físico en adultos mayores han mostrado tener beneficios a nivel físico, cognitivo y funcional. El objetivo de la presente tesis era investigar el efecto de diferentes programas de ejercicio físico en ancianos institucionalizados. El primer estudio se realizó con el objetivo de investigar el coste de la doble tarea en varias poblaciones de ancianos (ancianos robustos, ancianos frágiles con deterioro cognitivo leve, ancianos frágiles sin deterioro cognitivo leve y ancianos frágiles con demencia). Para ello, se categorizaron sesenta y cuatro hombres y mujeres ancianos en; a) robustos (edad 88,2 ± 4,1 años, n =10), b) frágiles con deterioro cognitivo leve (edad 92,4 ± 4,2 años, n =13), frágiles sin deterioro cognitivo leve (DCL) (edad 93,4 ± 3,2 años, n =20), y ancianos con demencia (edad 88,1±5,1 años, n =21). Se midieron la capacidad de caminar en 5 metros (5m) y el test de Timed up an Go (TUG) en tarea única y doble tarea. El coste de la tarea dual, tanto en el test de caminar con en el test de TUG se calculó mediante la diferencia en la realización de uno y otro. La segunda intervención fue un estudio longitudinal con el objetivo de investigar los efectos de dos intervenciones de ejercicio diferentes sobre el coste de los cuidados habituales, la capacidad funcional, la incidencia de caídas, la fuerza muscular y la función ejecutiva en ancianos institucionalizadas. Para ello se diseñó un ensayo clínico aleatorizado que investigaba el efecto de dos programas de ejercicio de 12 meses de duración en comparación con un grupo de cuidados habituales en ancianos frágiles institucionalizados. Con base a los resultados, se puede concluir que una intervención de ejercicio multicomponente de un año redujo el costo de la atención, mejoró la capacidad funcional y la fuerza muscular, así como redujo las caídas en los ancianos institucionalizados.

Muscle power is a strong predictor of functional status in the elderly population and is required to perform different daily activities. To compare the effects of different weekly training frequencies on muscle power and muscle quality induced by concurrent training (resistance + aerobic) in previously trained elderly men. Twenty-four trained elderly men (65 ± 4 years), previously engaged in a regular concurrent training program, three times per week, for the previous five months, were randomly allocated to concurrent training programs in which training was performed either twice a week (2·week-1, n = 12) or three times per week (3·week-1, n = 12). The groups trained with an identical exercise intensity and volume per session for 10 weeks. Before and after the exercise training, we examined muscle power, as estimated by countermovement jump height; knee extensor isokinetic peak torque at 60 and 180o.s-1; and muscle quality, a quotient between the one-repetition maximum of the knee extensors and the sum of quadriceps femoris muscle thickness determined by ultrasonography. Additionally, as secondary outcomes, blood pressure and reactive hyperemia were evaluated. Two-way ANOVA with repeated measures were used and statistical significance was set at α = 0.05. Muscular power (2·week-1: 7%, and 3·week-1: 10%) and muscle quality (2·week-1: 15%, and 3·week-1: 8%) improved with the concurrent exercise training (p < 0.001) but with no differences between groups. The isokinetic peak torque at 60 (2·week-1: 4%, and 3·week-1: 2%) and 180o.s-1 (2·week-1: 7%, and 3·week-1: 1%) increased in both groups (p = 0.036 and p=0.014, respectively). There were no changes in blood pressure or reactive hyperemia with the concurrent training. Concurrent training performed twice a week promotes similar adaptations in muscular power and muscle quality when compared with the same program performed three times per week in previously trained elderly men.

Effects of multicomponent exercise training on the intrinsic capacity in frail older adults: review of clinical trials
(Universidade Estadual Paulista, 2022) Mello, Alexandre; Izquierdo Redín, Mikel; Teodoro, Juliana Lopes; Lusa Cadore, Eduardo; Ciencias de la Salud; Osasun Zientziak
Aim: To review the effects of multicomponent exercise training on the domains of the intrinsic capacity of physically frail older adults: locomotion, vitality, cognition, psychological outcomes, and sensory function. Methods: The search for the studies was carried out in the MEDLINE, Cochrane CENTRAL, and PEDro databases, along with manual search, delimiting the period of publication as the last 10 years. The initial search identified 338 studies and 18 among them were analyzed qualitatively. Results: From the analysis of the included studies, great variability was evidenced between the intervention protocols, as well as between the results. As for the effectiveness of multicomponent exercise training, it has been shown to induce a positive effect on most of the analyzed outcomes. Conclusion: In summary, the present review suggests that multicomponent physical training can be effective to improve aspects of locomotion, cognition, and psychological aspects in frail older populations. Nevertheless, more studies are needed to specify the time needed to achieve such adaptations, the magnitude of these adaptations, and the design of the most appropriate training program for each outcome related to intrinsic capabilities.

Background: bed rest during hospitalization can negatively impact functional independence and clinical status of older individuals. Strategies focused on maintaining and improving muscle function may help reverse these losses. This study investigated the effects of a short-term multicomponent exercise intervention on maximal strength and muscle power in hospitalized older patients. Methods: this secondary analysis of a randomized clinical trial was conducted in an acute care unit in a tertiary public hospital. Ninety (39 women) older patients (mean age 87.7 ± 4.8 years) undergoing acute-care hospitalization [median (IQR) duration 8 (1.75) and 8 (3) days for intervention and control groups, respectively]) were randomly assigned to an exercise intervention group (n = 44) or a control group (n = 46). The control group received standard care hospital including physical rehabilitation as needed. The multicomponent exercise intervention was performed for 3 consecutive days during the hospitalization, consisting of individualized power training, balance, and walking exercises. Outcomes assessed at baseline and discharge were maximal strength through 1 repetition maximum test (1RM) in the leg press and bench press exercises, and muscle power output at different loads (≤ 30% of 1RM and between 45% and 55% of 1RM) in the leg press exercise. Mean peak power during 10 repetitions was assessed at loads between 45% and 55% of 1RM. Results: at discharge, intervention group increased 19.2 kg (Mean ∆% = 40.4%) in leg press 1RM [95% confidence interval (CI): 12.1, 26.2 kg; P < 0.001] and 2.9 kg (Mean ∆% = 19.7%) in bench press 1RM (95% CI: 0.6, 5.2 kg; P < 0.001). The intervention group also increased peak power by 18.8 W (Mean ∆% = 69.2%) (95% CI: 8.4, 29.1 W; P < 0.001) and mean propulsive power by 9.3 (Mean ∆% = 26.8%) W (95% CI: 2.5, 16.1 W; P = 0.002) at loads ≤30% of 1RM. The intervention group also increased peak power by 39.1 W (Mean ∆% = 60.0%) (95% CI: 19.2, 59.0 W; P < 0.001) and mean propulsive power by 22.9 W (Mean ∆% = 64.1%) (95% CI: 11.7, 34.1 W; P < 0.001) at loads between 45% and 55% of 1RM. Mean peak power during the 10 repetitions improved by 20.8 W (Mean ∆% = 36.4%) (95% CI: 3.0, 38.6 W; P = 0.011). No significant changes were observed in the control group for any endpoint. Conclusions An individualized multicomponent exercise program including progressive power training performed over 3 days markedly improved muscle strength and power in acutely hospitalized older patients.

Ejercicio físico en el anciano frágil: una manera eficaz de prevenir la dependencia
(Universidad Europea de Madrid, 2014) Izquierdo Redín, Mikel; Lusa Cadore, Eduardo; Casas Herrero, Álvaro; Ciencias de la Salud; Osasun Zientziak
Los beneficios del ejercicio físico en el envejecimiento y, específicamente, en la fragilidad han sido objeto de reciente investigación científica. En el anciano, la práctica de actividad física regular se asocia a una disminución del riesgo de mortalidad, de enfermedades crónicas, institucionalización, deterioro cognitivo y funcional. La práctica de ejercicio físico es la intervención más eficaz para retrasar la discapacidad y los eventos adversos que asocia habitualmente el síndrome de la fragilidad. De manera más concreta, el tipo de ejercicio físico más beneficioso en el anciano frágil es el denominado “entrenamiento multicomponente”. Este tipo de programas combina entrenamiento de fuerza, resistencia, equilibrio y marcha, y es con el que más mejorías se ha demostrado en la capacidad funcional, que es un elemento fundamental para el mantenimiento de la independencia en las actividades básicas de la vida diaria (ABVD) de los ancianos. Los objetivos deberían centrarse, por tanto, en mejorar dicha capacidad funcional a través de mejorías en el equilibrio y la marcha, así como mediante la disminución del riesgo y del número de caídas. Para la obtención de estos objetivos, el diseño de un programa de ejercicio físico en el anciano frágil debe acompañarse necesariamente de recomendaciones sobre variables tales como la intensidad, la potencia, el volumen y la frecuencia de entrenamiento ideales en esta población.

Enhancing health outcomes in institutionalized older adults: the critical role of combined exercise and nutritional interventions
(Springer, 2024) Lusa Cadore, Eduardo; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
Significant progress in health sciences has led to increased life expectancy, yet the potential to decelerate, halt, or reverse the aging process remains uncertain. This remarkable achievement has enabled many individuals to reach advanced ages in good health and with independence, enhancing their quality of life and time spent with family and friends. However, extending lifespan alone does not ensure independent aging or improved quality of life. Despite the additional years gained in recent decades, many adults do not engage in the recommended levels of physical activity. Consequently, these additional years are often marked by increased disability. Inactive aging leads to an unhealthy phenotype among the older population, characterized by diminished physical work capacity and a greater risk of non-communicable diseases. As individuals age, physical inactivity increases their risk of falls, fractures, ospitalizations, frailty, and institutionalization. In particular, the very elderly in institutional settings exhibit reduced functional and cognitive capacities, placing them at higher risk of frailty and disability. Older adults with low functional capacity, especially those institutionalized, are associated with increased public health expenditures compared to their healthier, noninstitutionalized counterparts [3]. Therefore, it is crucial to develop strategies to combat physical frailty in this vulnerable population. Among these, physical exercise interventions, especially those integrating exercise with nutritional support, have shown exceptional costeffectiveness in addressing frailty in institutionalized older adults.

Aging, a universal and inevitable process, is characterized by a progressive accumulation of physiological alterations and functional decline over time, leading to increased vulnerability to diseases and ultimately mortality as age advances. Lifestyle factors, notably physical activity (PA) and exercise, significantly modulate aging phenotypes. Physical activity and exercise can prevent or ameliorate lifestyle-related diseases, extend health span, enhance physical function, and reduce the burden of non-communicable chronic diseases including cardiometabolic disease, cancer, musculoskeletal and neurological conditions, and chronic respiratory diseases as well as premature mortality. Physical activity influences the cellular and molecular drivers of biological aging, slowing aging rates¿a foundational aspect of geroscience. Thus, PA serves both as preventive medicine and therapeutic agent in pathological states. Sub-optimal PA levels correlate with increased disease prevalence in aging populations. Structured exercise prescriptions should therefore be customized and monitored like any other medical treatment, considering the dose-response relationships and specific adaptations necessary for intended outcomes. Current guidelines recommend a multifaceted exercise regimen that includes aerobic, resistance, balance, and flexibility training through structured and incidental (integrated lifestyle) activities. Tailored exercise programs have proven effective in helping older adults maintain their functional capacities, extending their health span, and enhancing their quality of life. Particularly important are anabolic exercises, such as Progressive resistance training (PRT), which are indispensable for maintaining or improving functional capacity in older adults, particularly those with frailty, sarcopenia or osteoporosis, or those hospitalized or in residential aged care. Multicomponent exercise interventions that include cognitive tasks significantly enhance the hallmarks of frailty (low body mass, strength, mobility, PA level, and energy) and cognitive function, thus preventing falls and optimizing functional capacity during aging. Importantly, PA/exercise displays dose-response characteristics and varies between individuals, necessitating personalized modalities tailored to specific medical conditions. Precision in exercise prescriptions remains a significant area of further research, given the global impact of aging and broad effects of PA. Economic analyses underscore the cost benefits of exercise programs, justifying broader integration into health care for older adults. However, despite these benefits, exercise is far from fully integrated into medical practice for older people. Many healthcare professionals, including geriatricians, need more training to incorporate exercise directly into patient care, whether in settings including hospitals, outpatient clinics, or residential care. Education about the use of exercise as isolated or adjunctive treatment for geriatric syndromes and chronic diseases would do much to ease the problems of polypharmacy and widespread prescription of potentially inappropriate medications. This intersection of prescriptive practices and PA/exercise offers a promising approach to enhance the well-being of older adults. An integrated strategy that combines exercise prescriptions with pharmacotherapy would optimize the vitality and functional independence of older people whilst minimizing adverse drug reactions. This consensus provides the rationale for the integration of PA into health promotion, disease prevention, and management strategies for older adults. Guidelines are included for specific modalities and dosages of exercise with proven efficacy in randomized controlled trials. Descriptions of the beneficial physiological changes, attenuation of aging phenotypes, and role of exercise in chronic disease and disability management in older adults are provided.

Background: Exercise protocols applied during hospitalization can prevent functional and cognitive decline in older adults. The purpose of this study was to examine the individual response of acutely hospitalized patients to usual care and to physical exercise on functional capacity, muscle strength, and cognitive function and to assess the relationship with mortality at 1 year post-discharge. Methods: In a single-blind randomized clinical trial, 370 hospitalized patients [56.5% women; mean age (standard deviation) 87.3 (4.9) years] were allocated to an exercise intervention group (IG, n = 185) or a control group (CG, n = 185). The participants were older adults aged 75 years or older in an acute care unit in a tertiary public hospital in Navarra, Spain. The usual care group received habitual hospital care, which included physical rehabilitation when needed. The in-hospital intervention included individualized multicomponent exercise training programme performed during 5–7 consecutive days (two sessions/day). Functional capacity was assessed with the Short Physical Performance Battery (SPPB) test and the Gait Velocity Test (GVT). Handgrip strength and cognitive function were also measured at admission and discharge. Patients in both groups were categorized as responders (Rs), non-responders (NRs), and adverse responders (ARs) based on the individual response to each treatment during hospitalization. Results: The prevalence of Rs was higher and the prevalence of NRs and ARs was lower in the intervention group than in the control group for functional capacity (SPPB IG: Rs 85.3%, NRs 8.7%, ARs 6.0% vs. CG: Rs 37.9%, NRs 28.8%, ARs 33.3% and GVT IG: Rs 51.2%, NRs 47.3, ARs 1.6% vs. CG: Rs 18.0%, NRs 67.7%, ARs 14.3%), muscle strength (IG: Rs 62.3%, NRs 26.5%, ARs 11.3% vs. CG: Rs 20.0%, NRs 38.0%, ARs 42.0%), and cognition (IG: Rs 41.5%, NRs 57.1%, ARs 1.4% vs. CG: Rs 13.8%, NRs 76.6%, ARs 9.7%) (all P < 0.001). The ARs for the GVT in the control group and the ARs for the SPPB in the intervention group had a significantly higher rate of mortality than the NRs and Rs in the equivalent groups (0.01 and 0.03, respectively) at follow-up. Conclusions: Older patients performing an individualized exercise intervention presented higher prevalence of Rs and a lower prevalence of NRs and ARs for functional capacity, muscle strength, and cognitive function than those who were treated with usual care during acute hospitalization. An adverse response on functional capacity in older patients to physical exercise or usual care during hospitalization was associated with mortality at 1 year post-discharge.

International exercise recommendations in older adults (ICFSR): expert consensus guidelines
(Springer, 2021) Izquierdo Redín, Mikel; Merchant, R.A.; Morley, John E.; Anker, S.D.; Aprahamian, I.; Arai, H.; Aubertin-Leheudre, M.; Bernabei, R.; Lusa Cadore, Eduardo; Cesari, Matteo; Chen, L.-K.; Souto Barreto, Philipe de; Duque, Gustavo; Ferrucci, L.; Fielding, R.A.; García Hermoso, Antonio; Gutiérrez Robledo, L.M.; Harridge, S.D.R.; Kirk, B.; Kritchevsky, S.; Landi, F.; Lazarus, N.; Martin, F.C.; Marzetti, E.; Pahor, M.; Ramírez Vélez, Robinson; Rodríguez Mañas, Leocadio; Rolland, Y.; Ruiz, J.G.; Theou, O.; Villareal, D.T.; Waters, D.L.; Won Won, C.; Woo, J.; Vellas, Bruno; Fiatarone Singh, Maria; Ciencias de la Salud; Osasun Zientziak
The human ageing process is universal, ubiquitous and inevitable. Every physiological function is being continuously diminished. There is a range between two distinct phenotypes of ageing, shaped by patterns of living-experiences and behaviours, and in particular by the presence or absence of physical activity (PA) and structured exercise (i.e., a sedentary lifestyle). Ageing and a sedentary lifestyle are associated with declines in muscle function and cardiorespiratory fitness, resulting in an impaired capacity to perform daily activities and maintain independent functioning. However, in the presence of adequate exercise/PA these changes in muscular and aerobic capacity with age are substantially attenuated. Additionally, both structured exercise and overall PA play important roles as preventive strategies for many chronic diseases, including cardiovascular disease, stroke, diabetes, osteoporosis, and obesity; improvement of mobility, mental health, and quality of life; and reduction in mortality, among other benefits. Notably, exercise intervention programmes improve the hallmarks of frailty (low body mass, strength, mobility, PA level, energy) and cognition, thus optimising functional capacity during ageing. In these pathological conditions exercise is used as a therapeutic agent and follows the precepts of identifying the cause of a disease and then using an agent in an evidence-based dose to eliminate or moderate the disease. Prescription of PA/structured exercise should therefore be based on the intended outcome (e.g., primary prevention, improvement in fitness or functional status or disease treatment), and individualised, adjusted and controlled like any other medical treatment. In addition, in line with other therapeutic agents, exercise shows a dose-response effect and can be individualised using different modalities, volumes and/or intensities as appropriate to the health state or medical condition. Importantly, exercise therapy is often directed at several physiological systems simultaneously, rather than targeted to a single outcome as is generally the case with pharmacological approaches to disease management. There are diseases for which exercise is an alternative to pharmacological treatment (such as depression), thus contributing to the goal of deprescribing of potentially inappropriate medications (PIMS). There are other conditions where no effective drug therapy is currently available (such as sarcopenia or dementia), where it may serve a primary role in prevention and treatment. Therefore, this consensus statement provides an evidence-based rationale for using exercise and PA for health promotion and disease prevention and treatment in older adults. Exercise prescription is discussed in terms of the specific modalities and doses that have been studied in randomised controlled trials for their effectiveness in attenuating physiological changes of ageing, disease prevention, and/or improvement of older adults with chronic disease and disability. Recommendations are proposed to bridge gaps in the current literature and to optimise the use of exercise/PA both as a preventative medicine and as a therapeutic agent.

Multicomponent exercise with power training: a vital intervention for frail older adults
(Elsevier, 2024) Izquierdo Redín, Mikel; Lusa Cadore, Eduardo; Ciencias de la Salud; Osasun Zientziak
Maintaining functional abilities is critical for healthy aging. Physical inactivity in older adults is linked to chronic diseases, functional declines, and increased risks of multimorbidity, falls, hospitalization, institutionalization, and mortality. Exercise interventions are essential to improve function and health in this population. Recent advancements highlight the importance of tailored exercise prescriptions, cost impacts, minimal effective power training doses, and multicomponent interventions such as the VIVIFRAIL program. This review emphasizes the significance of multicomponent exercise with power training in improving physical function in frail older adults. Resistance and power training alone may not enhance gait and balance, but a 12-week multicomponent program combining these elements significantly improves various physical and cognitive outcomes. Economic analyses demonstrate that such interventions reduce healthcare costs by decreasing hospitalizations. The VIVIFRAIL program successfully implements these approaches in community and healthcare settings, underscoring the positive impact on the well-being of older adults. Ongoing research and implementation of multicomponent exercise programs are vital for promoting health and independence in the aging population.

Neuromuscular compartmentalization of the vastus medialis muscle: comparison of the activity of the vastus medialis obliquus and the vastus medialis longus by high density electromyography
(Sociedades Chilena, Argentina y Panamericana de Anatomía, 2021) Guzmán Venegas, Rodrigo Antonio; Lusa Cadore, Eduardo; Valencia, Óscar; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
Los estudios anatómicos describen que el músculo vasto medial (VM) se subdivide en dos componentes morfológicamente distintos, el vasto medial obliquus (VMO) y el vasto medial largo (VML). Sin embargo, existen discrepancias con respecto a la diferenciación funcional de estos componentes. El objetivo de este estudio fue comparar los niveles de activación del VMO y el VML mediante electromiografía de superficie de alta densidad. Doce mujeres jóvenes sanas (edad: 21,4 ± 2,0 años; peso: 58,1 ± 7,5 kg; altura: 1,6 ± 0,1 m), realizaron un ejercicio de rodilla de cadena cinética abierta durante el cual se registró la actividad EMG de la VMO y la VML con dos matrices dimensionales de 32 electrodos de superficie. Los ejercicios se realizaron con tres niveles de resistencia (5, 10 y 15% del peso corporal (PC)), considerando tres fases: concéntrica, isométrica y excéntrica. En la fase isométrica el VMO tuvo mayor activación que el VML con los tres niveles de resistencia (p
