Interventions

Behavioral : This study randomly assigned recreational runners with chronic ankle instability to either a blood flow restriction (BFR) combined exercise group or a non-BFR combined exercise group, and

in the experimental group, the cuffs were inflated to 80% of each individual’s arterial occlusion pressure, whereas in the control group, the cuffs were worn in a fully deflated state at 0 mmHg. The e
