Arterial blood pressure response to heavy resistance exercise.
TLDR
It was concluded that when healthy young subjects perform weight-lifting exercises the mechanical compression of blood vessels combines with a potent pressor response and a Valsalva response to produce extreme elevations in blood pressure. Expand
Gender differences in substrate for endurance exercise.
TLDR
It is concluded that, during moderate-intensity long-duration exercise, females demonstrate greater lipid utilization and less carbohydrate and protein metabolism than equally trained and nourished males. Expand
Effects of menstrual cycle on blood lactate, O2 delivery, and performance during exercise.
TLDR
While aerobic performance and the cardiorespiratory adaptations to exercise are not influenced by the phase of the menstrual cycle, performance of high-intensity exercise is improved, and lactate production appears to be decreased in the luteal phase when estradiol and progesterone levels are elevated. Expand
Skeletal muscle metabolic and ionic adaptations during intense exercise following sprint training in humans.
TLDR
Sprint training resulted in reduced anaerobic ATP generation during intense exercise, suggesting that aerobic metabolism was enhanced, which may allow increased time to fatigue. Expand
The Ontario cohort study of running-related injuries.
TLDR
The risk of injury was associated with increased running mileage but was relatively unassociated with other aspects of training, such as usual pace, usual running surface, hill running, or intense training. Expand
Physiological effects of tapering in highly trained athletes.
TLDR
This study examined some of the physiological and performance effects of three different tapers in highly trained athletes, finding that muscle glycogen concentration and citrate synthase activity increased significantly after ROT and HIT, and strength increased after all three tapers. Expand
Effect of pH on cardiorespiratory and metabolic responses to exercise.
TLDR
Changes in blood [HCO3-] and pH were shown to have major effects on metabolism in exercise which presumably were responsible for impaired endurance in male subjects. Expand
Operation Everest II: oxygen transport during exercise at extreme simulated altitude.
TLDR
The findings suggest that although glycogenolysis may be accentuated at low work loads, it may not be maximally activated at exhaustion, and with increasing altitude, blood lactate was progressively reduced at maximal exercise, whereas at any absolute and relative submaximal work load, blood latate was higher. Expand
Operation Everest. II: Nutrition and body composition.
TLDR
It is suggested that hypoxia can be sufficient cause for the weight loss and decreased food consumption reported by mountain expeditions at high altitude. Expand
