Summary

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

Conditions

  • Muscle Weakness
  • Muscle Loss

Interventions

OTHER

Muscle power training with velocity loss (VL) of 10%

Subjects followed a muscle power training for 8 weeks (2 sessions per week on alternate days) using the leg extension exercise, with similar relative intensity (50% 1RM). Between weeks one and four two series will be performed per session. Then the number of series will increase to three per session. The inter-set recovery period will be always of 2-min. Velocity loss will be of 10% (VL10) in each set.

Between weeks one and four two series will be performed per session. Then the number of series will increase to three per session. The inter-set recovery period will be always of 2-min. Velocity loss will be of 30% (VL30) in each set.
