Low Intensity Blood Flow Restriction Training Study

Completed · Not applicable · Has a placebo group

Conditions studied: Muscle Mass

In brief

The particpant will complete baseline testing by measuring subjects' quadriceps muscle thickness (cm) via ultrasound technology, as well as have them complete a one repetition maximum (1RM) test on the leg press machine and an isometric knee extension using a dynamometer - strength measures will be calculated for both right and left legs. After baseline testing, subjects will complete 6 weeks of the testing protocol that will consist of leg press exercises at 30% of their 1RM. Subjects will be randomized to either wear a cuff that partially restricts blood flow to the limb (Study Group), or to wear a cuff that does not restrict blood flow (Control Group). Exercises will be completed 2x/week and will take approximately 10 total minutes (5 for warm up, 5 for testing protocol) per session. After 6 weeks, muscle thickness, leg press 1RM, and quadriceps extension strength will be re-tested and compared to the initial measurements.
