syndrome is reduced subacromial space, which compresses the tissue in that region and causes inflammation and pain. 9 In wheelchair athletes, this injury is often present together with muscular imbalance, that is, greater strength of the shoulder abductors than adductors and higher strength of the inward

landing phase of a jump. The onset of adolescence (ie, around the peak height velocity [PHV]) is a particularly critical period for injuries because of (1) imbalances within muscle-tendon units of young athletes, (2) strength imbalances between the hamstrings and quadriceps, particularly in post

that eccKF and conKE peak at different knee joint angles. 7 These ratios therefore negate consideration of angle-matched torques, and also the consideration of ipsilateral imbalances in an extended position, where ACL injuries have previously been identified to most likely occur. 14 Previous studies

. 1 The fundamental cause is an imbalance in energy intake between calories consumed and calories expended. To prevent this imbalance, limiting calorie consumption and engaging in regular physical activity are key factors. Physical activity, in addition to the increase in energy expenditure

balance exists between F 0 and V 0 capacities (ie, the F–V slope) that maximizes ballistic performance. 3 , 18 , 19 These results suggest that resistance-training programs should seek not only to increase P 0 but also to reduce the F–V imbalance by selectively altering F 0 and V 0 . 3 , 20 To

pressure (COP). The COP is the point of application of the ground reaction force, which is a force vector obtained by summing all the forces between the foot/feet and the ground ( Winter, 2005 ). The COP is also considered a reflection of the system’s neuromuscular response to the imbalances of the body
