Summary

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.

Detailed description

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.

Conditions

• Dynapenia
• Aging
• Physical Impairment

Interventions

Type	Name	Description
OTHER	Exercise + Placebo group	1/2 of the subject will follow a mixed power training: 4 power exercises + 6 functional exercises combined to a placebo
OTHER	Exercise + Protein group	1/2 of the subject will receive 30 g/ d of protein (leucine+ vitD; divided in three equal doses: morning, afternoon and evening) + will follow a mixed power training: 4 power exercises + 6 functional exercises.
