Changes in Drop-Jump Landing Biomechanics During Prolonged Intermittent Exercise
BACKGROUND As injury rates rise in the later stages of sporting activities, a better understanding of lower extremity biomechanics in the later phases of gamelike situations may improve training and injury prevention programs. HYPOTHESIS Lower extremity biomechanics of a drop-jump task (extracted from a principal components analysis) would reveal factors associated with risk of anterior cruci...
متن کاملChanges in circulatory antioxidant status in horses during prolonged exercise.
Prolonged low-medium intensity exercise is associated with increased oxidative stress in humans. We hypothesized that competitive equine endurance racing would induce changes in circulatory antioxidants and produce systemic oxidative stress. Forty horses competing in a 140-km endurance race in warm conditions [shade temperature 15-19 degrees C; 62-88% relative humidity (%RH)] were sampled befor...
متن کاملCarotid baroreflex function during prolonged exercise.
The present investigation was designed to uncouple the hemodynamic physiological effects of thermoregulation from the effects of a progressively increasing central command activation during prolonged exercise. Subjects performed two 1-h bouts of leg cycling exercise with 1) no intervention and 2) continuous infusion of a dextran solution to maintain central venous pressure constant at the 10-mi...
متن کاملBrain glycogen decreases during prolonged exercise.
Brain glycogen could be a critical energy source for brain activity when the glucose supply from the blood is inadequate (hypoglycaemia). Although untested, it is hypothesized that during prolonged exhaustive exercise that induces hypoglycaemia and muscular glycogen depletion, the resultant hypoglycaemia may cause a decrease in brain glycogen. Here,we tested this hypothesis and also investigate...
متن کاملCardiovascular drift during prolonged exercise: new perspectives.
We propose that cardiovascular drift, characterized by a progressive decline in stroke volume after 10-20 min of exercise, is primarily due to increased heart rate rather tahn a progressive increase in cutaneous blood flow as body temperature rises.
