Brief summary: The purpose of this study is examine the effects of 8 weeks (3 days/week) of resistance exercise training in children 8 to 10 years of age on muscle strength, activation, and lipids of the vastus lateralis.


Eligibility criteria: Inclusion Criteria:

* Healthy volunteer males and females ages 8 - 10 years.

Exclusion Criteria:

* No history or ongoing neuromuscular diseases, musculoskeletal injuries, or a disease that effects metabolism.

Primary outcomes:
measure: Change in the muscular strength of leg extensors, as measured with isometric strength.
timeFrame: baseline, following the intervention (9 weeks)
Secondary outcomes:
measure: Change from baseline in motor unit firing rates during a 60% of maximal voluntary contraction (MVC).
