Hyperthermia and central fatigue during prolonged exercise in humans.
The present study investigated the effects of hyperthermia on the contributions of central and peripheral factors to the development of neuromuscular fatigue. Fourteen men exercised at 60% maximal oxygen consumption on a cycle ergometer in hot (40 degrees C; hyperthermia) and thermoneutral (18 degrees C; control) environments. In hyperthermia, the core temperature increased throughout the exerc...
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 کاملMechanisms of Fatigue during Prolonged Exercise in the Heat
Increase in body temperature is a major factor limiting endurance performance in the heat and it is shown in this thesis that the effects of raised body temperature on performance, perception and neuroendocrine response to exercise are mediated by an interaction of body temperatures. Prolactin has been used as an indicator of hypothalamic activity and the pathways regulating its release have be...
متن کاملThe Effects of Exercise and Gender on Heat Tolerance Time during Prolonged Heat Exposure
The U.S. Navy has recently begun to increase the number of female sailors stationed aboard ship and personnel staffing ratios on the majority of suface ships are to be 50% male and 50% female by the year 2000. There is concern the Navy's current heat exposure policy may not provide the appropriate guidance for female personnel because these heat exposure standards, commonly referred to as the t...
متن کاملEvidence for a release of brain-derived neurotrophic factor from the brain during exercise.
Brain-derived neurotrophic factor (BDNF) has an important role in regulating maintenance, growth and survival of neurons. However, the main source of circulating BDNF in response to exercise is unknown. To identify whether the brain is a source of BDNF during exercise, eight volunteers rowed for 4 h while simultaneous blood samples were obtained from the radial artery and the internal jugular v...
