Isotonic vs Isokinetic Leg Extensions: Differences in Neuromuscular Function
Why is this research being done?
This research is examining how changes in muscle oxygenation influence performance in young adults. Typically, exercise protocols with blood flow restriction are done an isotonic exercise machine, however this is not typical for gym equipment. This study will compare neuromuscular differences elicited by an isotonic leg extension machine versus an isokinetic dynamometer.
How long will the research last and what will I need to do?
There are 4 total visits that we expect will occur for an 8–21-day period. The first visit will require approximately 30 minutes of time and the following three visits will be approximately 60 minutes each. Total time for the entire study is approximately 3 hours and 30 minutes spread out over different 4 days.
