The effect of acute low-load resistance exercise with the addition of blood flow occlusion on muscle function in boys and men.

Purpose: In adults, low-load resistance training with blood flow occlusion (BFO) mimics strength increases that occur from high-load training, without the need to experience high mechanical stress. In view of child-adult differences in exercise responses, this study examined whether BFO during exercise elicits differential changes in maximal voluntary contraction (MVC) and electromyographical (EMG) activity in children and adults.

Methods: Sixteen men (24.
