Muscle strength and size are associated with various indicators of overall health and well-being. 1 A practical solution to developing strength and muscle size in individuals who may not be able to lift heavy loads is known as “blood flow restriction (BFR)” or “vascular occlusion” exercise. This

blood flow restriction (BFR), has been suggested as being similarly effective as moderate/high-load resistance training in increasing strength and muscle mass. 2 Although the physiological mechanisms regarding the improvement of strength and muscle mass after a low-load resistance training program with

The combination of physical exercise with a partial blood flow restriction (BFR) in the exercising extremity has gained increasing interest in both research settings and practical training applications. Previous investigations have demonstrated that low-load resistance training in combination with

Key Points ▸ The diagnosis of osteochondritis dissecans (OCD) requires familiarity with symptoms and etiology. ▸ Microfracture surgery has a return-to-participation rate of 58%. ▸ No evidence exists identifying the gold standard protocol for OCD intervention. ▸ Blood flow restriction therapy should

The response of calf-muscle strength, resting blood flow, and postocclusive blood flow (PObf) were investigated after 4 wk of low-load resistance training (LLRT) with and without blood-flow restriction in a matched-leg design. Ten untrained older individuals age 62–73 yr performed unilateral plantar-flexion LLRT at 25% 1-repetition maximum (1RM). One limb was trained with normal blood flow and the other had blood flow restricted using a pressure cuff above the knee. 1RM, isometric maximal voluntary contraction, and isokinetic strength at 0.52 rad/s increased (p < .05) more after LLRT with blood-flow restriction than with normal blood flow. Peak PObf increased (p < .05) after LLRT with blood-flow restriction, compared with no change after LLRT with normal blood flow. These results suggest that 4 wk of LLRT with blood-flow restriction may be beneficial to older individuals to improve strength and blood-flow parameters.

The current literature suggests that the blood flow restriction pressure be set relative to an individual’s arterial occlusion pressure (AOP) as this will account for the cuff used and the size of the limb to which the cuff is applied. 1 However, this method of blood flow restriction is available

metabolism progressively increases with sprint duration and the number of sprints. 11 , 12 As such, components of aerobic metabolism like blood flow and oxygen uptake/delivery may be important determinants of repeated-sprint ability. Lower limb compression garments have previously been suggested to provide

, when blood flow to the muscle is restricted or occluded during the exercise. 6 As such, persons for whom traditional high-load training may be too cumbersome, or even contraindicated, the option to adopt a lighter training load in combination with blood flow restriction (BFR) may offer an important
