ABSTRACT

Skeletal muscle represents 50% of total body weight in adults. It possesses metabolic, endocrine and thermoregulatory functions besides the well known role as the main movement effector. Aging entails a gradual loss of muscle mass (sarcopenia), strength (dinapenia), and functionality as a result of multiple physiological (neuronal, endocrine, muscular), and lifestyle (nutrition, physical activity) factors. Such changes result in metabolic and functional alterations such as decreased ability to perform daily tasks, difficulty to walk properly, taking the stairs and progressive health deterioration; all these lead to increasing dependency. Among the different proposed interventions, physical exercise and, more specifically strength exercise, has demonstrated great efficacy, resulting in qualitative and quantitative improvement in skeletal muscle performance. It is necessary to have proper knowledge and management of the different training variables (intensity, frequency, volume, recovery time, and exercise choice) in order to optimize the results of such training and be able to guarantee adequate and efficient exercise prescription for this problem. In the last decades, several new proposals for strength training (superimposed partial vascular occlusion training or mechanical vibration training) have been made, and they are currently being used as efficient methods improving the functionality of subjects with sarcopenia.
