| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Resistance exercise training | Experimental | Participants undergo 24 sessions of resistance exercise training over about 8 weeks. |
|
| Control | No Intervention | Participants do not perform resistance exercise training. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Resistance exercise training | Other | Participants will strength train via linear periodization resistance exercise training. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Change in the muscular strength of leg extensors, as measured with isotonic strength. | The score will reflect the strength of the leg extensors. The higher score, reflects greater muscular strength. | baseline, following the intervention (9 weeks) |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in thigh muscle cross-sectional area. | Scores are measured cross-sectional area from ultrasound images. The higher score, reflects greater muscle size of the leg extensors. | baseline, following the intervention (9 weeks) |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in intramyocellular lipids of the vastus lateralis, as measure with magnetic resonance spectroscopy | The score will reflect a concentration. The higher score, reflects more fat in the fibers. | baseline, following the intervention (9 weeks) |
| Change from baseline in extramyocellular lipids of the vastus lateralis, as measure with magnetic resonance spectroscopy |

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