Arm && Interventions

Group	Intervention	Description
Resistance exercise training	Resistance exercise training	Participants undergo 8 weeks (3 days/week) of resistance exercise training.

Primary Outcome Measures

Name	Time	Method
Change in the muscular strength of leg extensors, as measured with isometric strength.	baseline, following the intervention (9 weeks)	The score will reflect the strength of the leg extensors. The higher score, reflects greater muscular strength.

Secondary Outcome Measures

Name	Time	Method
Change from baseline in motor unit firing rates during a 60% of maximal voluntary contraction (MVC).	baseline, following the intervention (9 weeks)	Scores are measured with the slope from the firing rates versus recruitment threshold relationships from the 60%. The higher slope score reflects greater muscle activation.
Change from baseline in thigh muscle cross-sectional area.	baseline, following the intervention (9 weeks)	Scores are measured cross-sectional area from ultrasound images.
