Blood Flow Restriction Laboratory (BFR Lab)

UCF Division of Kinesiology


The primary focus of the UCF Blood Flow Restriction (BFR) Laboratory is to identify exercise and/or rehabilitation strategies that elicit the most robust physiological responses among men and women with a particular emphasis on neuromuscular and cardiovascular function. The laboratory examines various interventions to determine the applicability of exercise, devices, and/or external stimuli to promote or maintain human function in asymptomatic and clinical populations. The laboratory is currently applying BFR exercise as a rehabilitative strategy to help restore neuromuscular and muscle function among people with multiple sclerosis. The laboratory is also evaluating the utility of BFR as a countermeasure to offset the effects of prolonged spaceflight on cardiovascular function.


Our laboratory recruits participants to partake in research studies. Participation in our studies not only helps contribute to science, but can also be a fun learning experience.

Current Research Projects

CREW (Creatine and Resistance Exercise in Women)

This research is examining the changes in muscle size, muscle function, body composition, strength, and blood vessel health. Specifically, the changes in these variables over the course of 8 weeks of training with or without blood flow restriction (BFR) and the supplementation of creatine or placebo (dextrose, a sugar in the form of a powder which is the standard placebo). Creatine monohydrate (Cr) is the most popular supplement for athletes and benefits all populations, however women are still very hesitant to take it due to the misconception of weight gain. This study will look to measure those muscle and body changes with exercise.

The Effects of Blood Flow Restriction on Aerobic and Muscular Function

The purpose of this study is to compare muscular, neuromuscular, and metabolic differences in running at a high intensity to running at a moderate intensity with blood flow restriction. We are recruiting aerobically trained males and females to helps determine these differences. In total, the study involves four visits each lasting about 90 minutes for a total of 6 hours. By participating in this study, you will be given your VO2 max.

Exercise Thresholds

Consider taking part in a research study that uses different techniques, including EMG, VO2, and heart rate, to examine aerobic/anaerobic thresholds during three different maximal aerobic exercise tests. We are recruiting aerobically trained males and females to help us study different types of exercise thresholds and methods to assess the thresholds. A threshold is when our body switches from using oxygen (aerobic) to create energy to methods that used things like stored sugar (anaerobic) to create energy. This study involves 4 total visits for a total of 4-5 hours. After this study you can be provided with your VO2max and several of these thresholds.

Acute Effects of Resistance Exercise Among Individuals with MS

Consider taking part in a research study that seeks to examine the acute effects of BFR exercise training on patients with MS. This study involves 4 total visits, each lasting 60-90 minutes. During each visit, surface electromyography, heart rate, and blood flow restriction will be assessed during three types of BFR protocols to gain a better understanding of which is best for this population. This study will take place in the Kinesiology Labs, in the Education Complex on the main campus of the University of Central Florida.
