Comparing Vascular Responses to Aerobic Exercise With and Without Blood Flow Restriction in Young and Older Adults

"In the LIAE+BFR condition, participants will walk on a treadmill for 20 minutes at 30-40% of heart rate reserve (HRR), with a pneumatic cuff inflated to 1.3 times the individual's ankle systolic blood pressure, using a 5cm wide x 75cm long commercial cuff around each upper thigh.~Treadmill speed will be adjusted dynamically to maintain target intensities, while the incline remains at 1%. Heart Rate, the Modified Borg Rate of Perceived Exertion scale, and the Rating of perceived discomfort will be continuously monitored throughout both exercise sessions to ensure adherence to the prescribed intensity levels."

"In the HIIE condition, participants will perform a 20 minutes treadmill-based HIAE, alternating between 60-seconds high-intensity intervals at 60-89% HRR and 60-second active recovery intervals at 40-50% HRR.~Treadmill speed will be adjusted dynamically to maintain target intensities, while the incline remains at 1%. Heart Rate, the Modified Borg Rate of Perceived Exertion scale, and the Rating of perceived discomfort will be continuously monitored throughout both exercise sessions to ensure adherence to the prescribed intensity levels."
