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 and power, motor unit activation, and lipid profiles of the vastus lateralis.

Outcome Measures

Primary Outcomes (1)

  • Change in muscular power of the leg extensors, as measured with isokinetic strength testing.

    The score will reflect the muscular power of the leg extensors. The higher score, reflects greater muscular strength.

    Baseline, following the intervention (9 weeks)

Secondary Outcomes (1)

  • Change from baseline in thigh muscle cross-sectional area

    Baseline, following the intervention (9 weeks)

Other Outcomes (7)

  • Change from baseline in intramyocellular lipids of the vastus lateralis, as measure with magnetic resonance spectroscopy

    baseline, following the intervention (9 weeks)

  • Change from baseline in extramyocellular lipids of the vastus lateralis, as measure with magnetic resonance spectroscopy

    baseline, following the intervention (9 weeks)

  • Change from baseline in the fatty acid saturation levels of the extramyocellular lipids of the vastus lateralis, as measure with magnetic resonance spectroscopy

    baseline, following the intervention (9 weeks)

  • +4 more other outcomes
