The goal of this quasi-experimental pilot study is to evaluate the effect of a multi-component intervention in women between 55 and 75 years old at risk of sarcopenia. The main question it aims to answer are: What is the effect of a multi-component intervention in women at risk of sarcopenia? Participants will twelve women between 55 and 75 years old with risk of sarcopenia, who agreed through written informed consent for participate 12 weeks with 24 sessions included dancing, resistance exercises, and nutritional education. The outcomes were muscle mass, grip strength, gait speed and body composition. The effects were measured before and after the intervention, under a self-controlled design.

Physical exercise, especially resistance exercise, is one of the best non-pharmacological treatment alternatives due to its multiple health benefits and could be a promoter for the prevention of sarcopenia by delaying muscle atrophy produced by the natural aging process. However, scientific literature shows that this activity when combined with other strategies has a better effect on sarcopenia indicators than alone. Dance is a social activity that is part of the culture and life history of human beings, however, current research has focused on studying the cognitive and visuospatial effects of this activity. It could be an activity with beneficial effects on the physical abilities of the individual since dancing improves flexibility, resistance and balance. However, the study of these two strategies, along with nutritional education has been little studied.

Therefore, a pilot test was proposed with the aim of knowing the possible effect of a multicomponent intervention on muscle, strength, performance, and body composition on women at risk of sarcopenia.
