Light load BFR resistance training
Heavy load resistance training
This arm of the clinical trial will involve eight weeks of twice weekly light load resistance training with BFR. Patients in this arm will complete four sets (30, 15, 15 and 15 repetitions, respectively) of unilateral leg press exercise at 30% of predicted one repetition maximum. BFR will be applied at 80% of total limb arterial occlusive pressure. Both legs will be trained, with the affected limb trained first and the unaffected limb matched for volume at a relative percentage of one repetition maximum. Both legs will be trained with BFR.
This arm of the clinical trial will involve eight weeks of twice weekly heavy load resistance training. Patients in this arm will complete three sets of ten repetitions of unilateral leg press exercise at 70% of predicted one repetition maximum. Both legs will be trained, with the affected limb trained first and the unaffected limb matched for volume at a relative percentage of one repetition maximum.
