Effect of exercise training on muscle strength and fitness in older women and men
Notice bibliographique
Résumé
Aging is characterized by progressive muscle mass and strength loss, commonly called sarcopenia. Sarcopenia may lead to the development of mobility limitations, increased risk of falls, and, ultimately, frailty. Periods of disuse, such as hospital stays, injury, or illness, can accelerate the onset of sarcopenia and increase the risk for disability. Evidence suggests that participating in physical activity, namely resistance training and aerobic exercise, can help to mitigate the risks of sarcopenia and maintain physical function and mobility as individuals age. Cognizant of the beneficial effects of exercise on muscle health, the Canadian Society for Exercise Physiology encourages older adults to participate in 150 minutes of moderate-vigorous aerobic exercise and perform resistance training at least 2 days/week. Older adults regularly participating in resistance training will be protected against developing sarcopenia-induced functional declines. However, many older adults are currently not resistance training or meeting the 24-hour movement guidelines proposed by the Canadian Society for Exercise Physiology (CSEP). A key reason for older adults not being physically active is that many traditional training programs are not sustainable for older adults and do not have lasting effects. Older adults also experience several barriers to executing resistance training, such as costs, access to equipment, fear of injury and low self-efficacy. Recent studies show that performing resistance training with elastic bands (increase in size and resistance based on their colours) and/or one’s own body weight effectively improve muscle strength, physical capacity, and activities of daily living in older adults in supervised clinical settings such as long-term care facilities and patients with sarcopenic obesity. Therefore, a new resistance training program that is accessible and helps to improve or maintain muscle strength, size and physical function in older adults is needed. We propose using resistance bands to improve the sustainability of a resistance training program for healthy older adults. Therefore, the primary objective of the study will be to determine the effectiveness of a 6-week supervised exercise training program that is in accordance with the Canadian physical activity guidelines (consisting of 3 days/week of aerobic exercise training and 2 days/week of bodyweight and elastic band-based resistance exercise training), on muscle mass, skeletal muscle anabolic signaling, strength, physical function, and cognitive function, in healthy older adults. A secondary objective of the study will be to recruit healthy young adults as a comparator for aforementioned outcomes.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
