Multicomponent Intervention in Women at Risk of Sarcopenia
Condition: Sarcopenia; Grip Strength; Gait Speed; Body Composition
MeSH terms: Sarcopenia
Study type: Interventional

Summary: 
      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.
    

Detailed description: 
      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.
    

Intervention name(s): Multicomponent intervention of resistance exercises, dancing sessions and nutritional education
Intervention type(s): Other
Intervention description(s): The intervention consisted of two sets of ten repetitions of resistance exercises, the second month four sets of eight repetitions, and the third month four sets of fifteen repetitions. It was estimated that each session (dance + resistance exercise) generated a caloric expenditure of 270.85 calories corresponding to 4.5 and 3.5 METs per activity. The resistance exercises and the dance sessions began and with a warm-up and stretching session 10 min, followed by the resistance exercises 30 min and dancing practice 30 min. The session ended with a cooling down session 10 min. The nutritional education offered included weekly topics lasting 20 min, on basic concepts of nutrition and recommended diet for the maintenance of skeletal muscle mass. Reinforcement of the topics was carried out through triptychs that were provided throughout the 12 sessions.
