简要总结
The main objectives of this study are to evaluate safety and chronic effects of a low-load resistance exercise intervention (elbow flexions and extensions, and knee extensions) with blood flow restriction in people with hemophilia on quality of life, pain, and on physical and neuromuscular function.

研究组 & 干预措施
Control
The training program for the control group consists of a telerehabilitation with traditional moderate-to-high load (60%-80% 1RM) exercises (the same as the intervention group sans BFR), utilizing elastic bands. This program for the control group will be conducted in an in-home real-time audio and video style and supervised by a physiotherapist.
干预措施: Control
BFRT
The BFR training program for the intervention group consists of elbow flexion and extension, and knee extension exercises performed with low load (elastic bands; equivalent to 30% 1RM) and concurrent BFR (upper limb 50% AOP; lower limb 60% AOP). Subjects will perform 4 sets (30, 15, 15 and 15 reps) of each exercise with 30 s rest between sets and 5-minute rest between exercises.
干预措施: BFRT
