Power Training on Muscle Quality and Functional Capacity in Women Aged 65-75.

Muscle power training has proven to be an effective intervention to prevent sarcopenia and frailty in old people. In the last decade, new concepts related to the functionality of old people have been generated, such as muscle quality and functional capacity. The power training consists of rapid movements of short duration that imply a more specialized neuromuscular response and that improve the functional response reflected in activities of daily life that demand a certain manifestation of muscular power (stand up of a chair, climbing stairs, rebalance, accelerate suddenly, among others). Therefore, it is important to investigate the dose-response relationships in power training in older people and establish how possible improvements in muscle quality can be reflected in functional capacity. The aim of this study is to compare the effects of power training at two different loads on muscle quality and functional capacity in women aged 65-75
