    Intensity training and cardiovascular health in Colombian adults: results from HIIT-Heart Study and Cardiometabolic HIIT-RT Study
    (2018) Ramírez Vélez, Robinson; Izquierdo Redín, Mikel; Correa Bautista, Jorge Enrique; Ciencias de la Salud; Osasun Zientziak
    The current Ph.D. dissertation revolves around the relationship between exercise intensity and improvement cardiometabolic health. It has been suggested that high intensity interval training and also moderate or resistance training generate positive effects on metabolic risk factors. For these reasons, it is necessary to clarify which type of training, is more effective to improve cardiometabolic health in Latin American population. This doctoral thesis is based on 6 scientific studies that have been published or submitted for publication in scientific international journals. The first study (Chapter 2), we aimed to determine the effects of moderate- versus high-intensity interval exercise training on vascular function parameters in physically inactive adults. The second study (Chapter 3) to compare the effects of high-intensity interval training and steady-state moderate-intensity training on clinical components of metabolic syndrome (MetS) in healthy physically inactive adults. The third study (Chapter 4), we investigated the effect of moderate versus high-intensity interval exercise training on the HRV indices in physically inactive adults. Study five (Chapter 6) are Lab-based studies to evaluate the chronic impact of MCT or HIT on biomarkers of endothelial function, arterial stiffness and heart rate variability parameters postprandially after a high-fat meal. The last study of the current Ph.D. dissertation we aimed to investigate whether 12 weeks of high-intensity interval training (HIIT), resistance training (RT), concurrent training (CT=HIII+RT) or nutritional guidance (NG) induced improvements in metabolic syndrome (MetS) risk factors, vascular function parameters and ideal cardiovascular health (CVH) in sedentary and overweight adults, and to compare the training adaptations between intervention groups.

    Assessing basic motor competences, physical fitness, and executive function in 4-5-year-old children: a longitudinal study in a primary care setting
    (BMC, 2024) Legarra Gorgoñón, Gaizka; García Alonso, Yesenia; Ramírez Vélez, Robinson; Alonso Martínez, Loreto; Izquierdo Redín, Mikel; Alonso Martínez, Alicia; Ciencias de la Salud; Osasun Zientziak
    Background: To evaluate the progression of physical fitness (PF), basic motor competence (BMC), and executive function (EF) over one year in children aged 4-5 years at a health center. Methods: In this longitudinal analysis, children's BMC was evaluated using the MOBAK KG test for object and self-movement. The PREFIT Battery gauged PF through handgrip strength, standing long jump, and other fitness measures, while the Early Years Toolbox appraised EF. Results: Adjustments for confounding factors showed notable improvements in BMC, particularly in object movement (OM; mean difference 0.789, p=0.044) and self-movement (SM; mean difference 0.842, p=0.037), with overall MOBAK scores also increasing (mean difference 1.632, p=0.018). Enhancements in the standing long jump (mean difference 9.036 cm, p=0.014) and EF tasks "Mr. Ant" (mean difference 0.669, p<0.001) and "Go/No-Go" (mean difference 0.120, p<0.001) were evident, signifying substantial BMC gains and some progress in PF and EF. Conclusion: This research underscores the positive impact of regular training on BMC and PF in young children. Significant BMC development and associated improvements in PF and EF over the study period highlight the importance of structured activities in early childhood. These findings advocate for standardized training programs to enhance childhood health and encourage active lifestyles.

    The challenge of promoting physical activity in low-income and middle-income countries
    (Elsevier, 2023) Ramírez Vélez, Robinson; Silva, Danilo R.; Ciencias de la Salud; Osasun Zientziak
    Physical inactivity is one of the main public health problems worldwide. Public awareness of the benefits of physical activity has increased, and advances have been made in the field of physical activity epidemiology. Findings also show that the prevalence of physical activity at the WHO-recommended level (≥150 min of moderate-intensity or 75 min of vigorous-intensity physical activity per week, or equivalent combinations1) has been stable in recent decades.2 Nevertheless, promoting physical activity in the least active groups remains a considerable challenge. Latin America is a good example of the size of this challenge, as it is the region with the highest prevalence of physical inactivity in the world.1 The region is composed mainly of low-income and middle-income countries (LMICs), characterised by recent urbanisation, large cultural differences within populations, and social inequalities.

    (Oxford University Press, 2024-11-22) Ramírez Vélez, Robinson; Oteiza Olaso, Julio; Legarra Gorgoñón, Gaizka; Oscoz Ochandorena, Sergio; García Alonso, Nora; García Alonso, Yesenia; Correa Rodríguez, María; Soto-Mota, Adrian; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Ciencias humanas y de la educación; Giza eta Hezkuntza Zientziak
    Background: the post-COVID-19 condition is a novel condition for which guidelines recommend supervised exercise, but evidence guiding safe and effective interventions is limited. The aim of this study was to investigate the effects of a tailored exercise program (EXER-COVID 5 trial) on cardiorespiratory fitness, muscle strength, long COVID symptoms, cognitive performance, quality of life, depression, and psychological distress. Methods: this crossover study included 100 participants with post-COVID-19 conditions (mean 8 age 48 years; 68% women) at a single center in Spain from March 1, 2021, to September 30, 2022. Participants were randomized 1:1 to 6 weeks of muscle power resistance training (PRT) followed by 6 weeks of usual care (Group 1 [AB], n=50) or 6 weeks of usual care followed by 6 weeks of muscle power RT (Group 2 [BA], n=50). Results: the intervention significantly improved the peak VO2 by 2.10 mL/kg/min [95% CI 1.25 to 2.94], P<0.001. Per-protocol analyses revealed similar results (2.40 mL/kg/min [95% CI 1.56 to 3.25]), P<0.001. No carry-over or period effects were detected. After power PRT, strength (1RM) was improved for pectoral press, bilateral leg-press, knee extension, and back press (P<0.001). Significant decreases were found in psychological distress scores (P<0.001). The intervention also improved quality of life (P=0.041), cognitive capabilities (P=0.014) and cognitive performance (P=0.036). Furthermore, the exercise program reduced seven of the 22 long-COVID symptoms, including weakness (RR= 0.75) dyspnea (RR= 0.56), hearing loss/tinnitus (RR= 0.86), change in appetite (RR= 0.84), memory loss (RR= 0.84), stress (RR= 0.80) and apathy/depression (RR= 0.80), (all Ps<0.05). Conclusions: a supervised 6-week PRT intervention program safely improved cardiorespiratory fitness, strength, and mental health in participants with post-COVID-19 conditions. These findings provide clinicians with evidence to support exercise as standard co-therapy and warrant further study.

    Mode of commuting to school and its association with physical activity and sedentary habits in young ecuadorian students
    (MDPI, 2018) Barranco Ruiz, Yaira; Guevara-Paz, Alfredo Xavier; Ramírez Vélez, Robinson; Chillón, Palma; Villa González, Emilio; Ciencias de la Salud; Osasun Zientziak
    Active commuting to and from school (ACS) could help to increase daily physical activity levels in youth; however, this association remains unknown in Ecuadorian youth. Thus, the aims of this study were (1) to determine the patterns of commuting to and from school and (2) to analyze the associations between ACS, physical activity (PA), and sedentary habits in Ecuadorian youth. A total of 732 students (65.3% males), aged 10–18 years (children = 246, young adolescents = 310, older adolescents = 162) from the central region of Ecuador participated in this study. A self-report questionnaire, including the usual mode and frequency of commuting, distance from home to school (PACO-Questionnaire), and PA and sedentary habits (YAP-Questionnaire), was used. Most of the sample lived ≤2 km from school; however, they were mainly passive commuters (96%). The most common mode of commuting was by car (to school = 43.4%, from school = 31.6%; p < 0.001). Children presented significantly higher scores (0–4) in PA outside school and total PA compared with older adolescents (2.20 ± 0.97 vs. 1.97 ± 0.96; p = 0.013 and 2.30 ± 0.76 vs. 2.09 ± 0.74, p = 0.019, respectively), as well as the lowest scores in sedentary habits (1.51 ± 0.65, p < 0.001). PA at school and total PA were positively associated with ACS (OR 3.137; 95% CI, 1.918 to 5.131; p < 0.001, and OR 2.543; 95% CI, 1.428 to 4.527; p = 0.002, respectively). In conclusion, passive modes of transportation were the most frequently used to commute to and from school in young Ecuadorians. PA at school and total PA were positively associated with ACS. Thus, interventions at school setting could be an opportunity to improve PA levels and additionally ACS in youth from the central region of Ecuador.

    Pubertal stage, body mass index, and cardiometabolic risk in children and adolescents in Bogotá, Colombia: the cross-sectional FUPRECOL study
    (MDPI, 2017) Ramírez Vélez, Robinson; García Hermoso, Antonio; Agostinis-Sobrinho, César; Mota, Jorge; Santos, Rute; Correa Bautista, Jorge Enrique; Peña-Guzmán, Carlos Andrés; Domínguez Sánchez, María Andrea; Schmidt Río-Valle, Jacqueline; González Jiménez, Emilio; Ciencias de la Salud; Osasun Zientziak
    This study explored the association between pubertal stage and anthropometric and cardiometabolic risk factors in youth. A cross-sectional study was conducted in 2877 Colombian children and adolescents (9¿17.9 years of age). Weight, height, and waist circumference were measured and body mass index (BMI) was calculated. A biochemical study was performed to determine the cardiometabolic risk index (CMRI). Blood pressure was evaluated and pubertal stage was assessed with the Tanner criteria. Hierarchical multiple regression analyses were performed. The most significant variable (p < 0.05) in the prognosis of cardiometabolic risk was found to be the BMI in both boys and girls. In the case of girls, the pubertal stage was also a CMRI predictive factor. In conclusion, BMI was an important indicator of cardiovascular risk in both sexes. Pubertal stage was associated with cardiovascular risk only in the girls.

    Internal consistency and content validity of a questionnaire aimed to assess the stages of behavioral lifestyle changes in colombian schoolchildren: the FUPRECOL study
    (Pontifícia Universidade Católica de Campinas, 2017) Carrillo-Bernate, Yasmira; Correa Bautista, Jorge Enrique; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
    Objective To assess internal consistency and content validity of a questionnaire aimed to assess the stages of Behavioural Lifestyle Changes in a sample of school-aged children and adolescents aged 9 to 17 years-old. Methods This validation study involved 675 schoolchildren from three official school in the city of Bogota, Colombia. A self-administered questionnaire called Behavioural Lifestyle Changes has been designed to explore stages of change regarding to physical activity/exercise, fruit and vegetable consumption, alcohol abuse, tobacco use, and drug abuse. Cronbach-α, Kappa index and exploratory factor analysis were used for evaluating the internal consistency and validity of content, respectively. Results The study population consisted of 51.1% males and the participants' average age was 12.7±2.4 years-old. Behavioural Lifestyle Changes scored 0.720 (range 0.691 to 0.730) on the Cronbach ¿ and intra-observer reproducibility was good (Kappa=0.71). Exploratory factor analysis determined two factors (factor 1: physical activity/exercise, fruit and vegetable consumption, and factor 2: alcohol abuse tobacco use and drug abuse), explaining 67.78% of variance by the items and six interactions χ2/gL=11649.833; p < 0.001. Conclusion Behavioural Lifestyle Changes Questionnaire was seen to have suitable internal consistency and validity. This instrument can be recommended, mainly within the context of primary attention for studying the stages involved in the lifestyle behavioural changes model on a school-based population.

    Short-term multicomponent exercise impact on muscle function and structure in hospitalized older at risk of acute sarcopenia
    (Wiley, 2024-10-13) López Sáez de Asteasu, Mikel; Martínez Velilla, Nicolás; Zambom Ferraresi, Fabrício; García Alonso, Yesenia; Galbete Jiménez, Arkaitz; Ramírez Vélez, Robinson; 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
    Background. Hospitalization exacerbates sarcopenia and physical dysfunction in older adults. Whether tailored inpatient exercise prevents acute sarcopenia is unknown. This study aimed to examine the effect of a multicomponent exercise programme on muscle and physical function in hospitalized older adults. We hypothesized that participation in a brief tailored exercise regimen (i.e., 3–5 days) would attenuate muscle function and structure changes compared with usual hospital care alone. Methods. This randomized clinical trial with blinded outcome assessment was conducted from May 2018 to April 2021 at Hospital Universitario de Navarra, Spain. Participants were 130 patients aged 75 years and older admitted to an acute care geriatric unit. Patients were randomized to a tailored 3- to 5-day exercise programme (n = 64) or usual hospital care (control, n = 66) consisting of physical therapy if needed. The coprimary endpoints were between-group differences in changes in short physical performance battery (SPPB) score and usual gait velocity from hospital admission to discharge. Secondary endpoints included changes in rectus femoris echo intensity, cross-sectional area, thickness and subcutaneous and intramuscular fat by ultrasound. Results. Among 130 randomized patients (mean [SD] age, 87.7 [4.6] years; 57 [44%] women), the exercise group increased their mean SPPB score by 0.98 points (95% CI, 0.28–1.69 points) and gait velocity by 0.09 m/s (95% CI, 0.03–0.15 m/s) more than controls (both p < 0.01). No between-group differences were observed in any ultrasound muscle outcomes. There were no study-related adverse events. Conclusions. Three to 5 days of tailored multicomponent exercise provided functional benefits but did not alter muscle or fat architecture compared with usual hospital care alone among vulnerable older patients. Brief exercise may help prevent acute sarcopenia during hospitalization.

    Ideal cardiovascular health predicts lower risk of abnormal liver enzymes levels in the Chilean National Health Survey (2009-2010)
    (Public Library of Science, 2017) García Hermoso, Antonio; Hackney, Anthony C.; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
    High levels of gamma glutamyltransferase (gamma-GT) and alanine aminotransferase (ALT), as well as fatty liver index (FLI) has been associated with higher cardiovascular disease risk factors in adults. The aim of this study was to examine the relationship between gamma-GT, ALT, and fatty liver index FLI levels across a gradient number of ideal cardiovascular health metrics in a representative sample of adults from the Chilean National Health Survey 2009-2010. Data from 1,023 men and 1,449 women (¿ 15 years) from the Chilean Health Survey 2009¿2010 were analyzed. Ideal cardiovascular health was defined as meeting ideal levels of the following components: four behaviours (smoking, body mass index, physical activity and diet adherence) and three factors (total cholesterol, blood pressure and fasting glucose). Adults were grouped into three categories according to their number of ideal cardiovascular health metrics: ideal (5¿7 metrics), intermediate (3¿4 metrics), and poor (0¿2 metrics). Blood levels of gamma-GT and ALT were measured and the FLI was calculated. A higher number of ideal cardiovascular health index metric was associated with lower gamma-GT, ALT and FLI (p from trend analysis <0.001). Also, adults meeting at least 3-4 metrics were predicted less likely to have prevalence of abnormal levels of gamma-GT and FLI (p<0.001) compared to adults who met only 0¿2 metrics. These findings reinforce the usefulness of the ideal cardiovascular health metrics proposed by the American Heart Association as a tool to identify target subjects and promote cardiovascular health in South-American adults.
