What will be asked of you

At each visit, you will perform a maximal strength assessment for both your quadriceps and hamstrings muscles. You will then be asked to hold a percentage of your maximal strength for as long as you can. At one of the visits, you will be asked to perform mental math during the fatiguing task. During all tasks, heart activity will be monitored. At the initial visit, you will also complete a questionnaire and perform a body composition scan.

Incentives

A body composition scan (DXA) as well as information on maximal quadriceps and hamstring strength

In-person visits:
2

Total length of participation:
1-2 weeks (2 visits, 4-14 days apart)
