简要总结
Investigate the effect of 12 weeks mixed power training (power and functional exercises) combined with a protein supplementation (30g/d) or not (placebo) on physiological characteristics of muscle and functional capacities in elderly men.
详细描述
Life habits are know to be able to prevent the loss of functional capacities and muscle function during aging process. More specifically, protein intake is important to maintain muscle function in older adults. Another non pharmacological intervention and well recognized for its efficacy, it's exercise training.
Recently, it has been observed than muscle quality is more important to maintain physical autonomy than muscle mass per se. In addition, muscle quality is more related to functional capacities than muscle mass.
Due to this recent finding, it has been proposed that muscle power training would be the best exercise intervention to prevent the loss of mobility.
