Blood Flow Restriction During High-intensity Interval Exercise

The study is a randomized controlled trial aimed to compare the effects of blood flow restriction (BFR) in different phases (i.e., exercise versus interval) during high-intensity interval exercise (HIIE) on aerobic capacity, anaerobic capacity, isokinetic knee strength, lower limb biomechanics during single-leg landing and cycling economy among healthy adult males. Participants were randomized to three groups. Intervention was conducted for 12 weeks with 2 sessions per week. During intervention, all groups conducted HIEE on cycle ergometer with or without BFR. Assessments were conducted before the intervention, on the 6th week of intervention and after the intervention. Assessments included physical characteristics, aerobic and anaerobic capacity, lower limb biomechanics during single-leg landing and isokinetic knee strength.
