Design outcomes

Primary

Measure	Time frame	Description
Change in the muscular strength of leg extensors, as measured with isotonic 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

Measure	Time frame	Description
Change from baseline in thigh muscle cross-sectional area.	baseline, following the intervention (9 weeks)	Scores are measured cross-sectional area from ultrasound images. The higher score, reflects greater muscle size of the leg extensors.

Other

Measure	Time frame	Description
Change from baseline in intramyocellular lipids of the vastus lateralis, as measure with magnetic resonance spectroscopy	baseline, following the intervention (9 weeks)	The score will reflect a concentration. The higher score, reflects more fat in the fibers.
Change from baseline in extramyocellular lipids of the vastus lateralis, as measure with magnetic resonance spectroscopy	baseline, following the intervention (9 weeks)	The score will reflect a concentration. The higher score, reflects more fat in the fibers.
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)	The score will reflect a saturation level of fatty acids in the extramyocellular lipid. The higher score, reflects greater fatty acid saturation.
Change from baseline in the fatty acid saturation levels of the intramyocellular lipids of the vastus lateralis, as measure with magnetic resonance spectroscopy	baseline, following the intervention (9 weeks)	The score will reflect a saturation level of fatty acids in the intramyocellular lipid. The higher score, reflects greater fatty acid saturation.
