CHPS RESEARCH STUDIES

Isometric muscle fatigue and EMG signal processing

This research is being done to compare how muscles respond during different types of maximal and below maximal muscular contractions with and without blood flow restriction. There are 2 total visits that must have at least 48 hours between them. The first visit will last about 60-90 minutes. The following visit will last about 90 minutes. The total time for the entire study is about 2.5-3 hours spread out over different 2 days. For this study, you will be asked to complete several sets of leg extensions which will range from maximal effort to low effort. During these exercises, electromyography electrodes and mechanomyography devices will be attached to your leg. Electromyography measures the electrical activity of the muscles beneath it and mechanomyography measures muscle movement. Additionally, a blood flow restriction device, which is very similar to a blood pressure cuff (Figure 2), will be attached to the top of one of your thighs for all of the exercises. This device will partially restrict blood flow to the leg but will not fully restrict blood flow. These devices will be attached to your leg during the study so please wear shorts for both visits.
