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.

Strength and endurance training prescription in healthy and frail elderly
(International Society on Aging and Disease (ISOAD), 2014) Lusa Cadore, Eduardo; Pinto, Ronei Silveira; Bottaro, Martim; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
Aging is associated with declines in the neuromuscular and cardiovascular systems, resulting in an impaired capacity to perform daily activities. Frailty is an age-associated biological syndrome characterized by decreases in the biological functional reserve and resistance to stressors due to changes in several physiological systems, which puts older individuals at special risk of disability. To counteract the neuromuscular and cardiovascular declines associated with aging, as well as to prevent and treat the frailty syndrome, the strength and endurance training seems to be an effective strategy to improve muscle hypertrophy, strength and power output, as well as endurance performance. The first purpose of this review was discuss the neuromuscular adaptations to strength training, as well as the cardiovascular adaptations to endurance training in healthy and frail elderly subjects. In addition, the second purpose of this study was investigate the concurrent training adaptations in the elderly. Based on the results found, the combination of strength and endurance training (i.e., concurrent training) performed at moderate volume and moderate to high intensity in elderly populations is the most effective way to improve both neuromuscular and cardiorespiratory functions. Moreover, exercise interventions that include muscle power training should be prescribed to frail elderly in order to improve the overall physical status of this population and prevent disability.

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.

Effects of different concurrent resistance and aerobic training frequencies on muscle power and muscle quality in trained elderly men: a randomized clinical trial
(Aging and Disease, 2016) Ferrari, Rodrigo; Fuchs, Sandra C.; Kruel, Luiz Fernando Martins; Lusa Cadore, Eduardo; Alberton, Cristine Lima; Pinto, Ronei Silveira; Radaelli, Régis; Schoenell, Maira; Izquierdo Redín, Mikel; Tanaka, Hirofumi; Umpierre, Daniel; Ciencias de la Salud; Osasun Zientziak
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.

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.
