This study uses magnetic resonance imaging to investigate the relationship between muscle use and progressive increases in oxygen consumption during intense cycling. Results indicate that muscle activation during intense exercise is associated with increases in oxygen uptake due to motor unit stimulation and higher energy demands.

Research indicates that there is no change in the density of fat-free mass when weight loss is induced by diet or diet and exercise. Results are based on a study of seventy four obese women; topics include body composition, diet and exercise regimes, and water and mineral fractions of the fat-free mass.

A study was conducted to compare the effect of carbohydrate-protein-antioxidant beverage (CHOPA) to an isocaloric carbohydrate-only beverage on time to fatigue and muscle damage. The data showed no differences in time to fatigue between beverages in spite of lower total carbohydrate content in the CHOPA beverage.

The effects of consumption of carbohydrate and protein beverage on continuous cycling performance and post exercise muscle damage were determined. The results indicate that a carbohydrate-protein beverage generated notable improvements in time to exhaust and decrease in muscle damage in endurance athletes.

An investigation to trace the effects of 4 week of endurance training on end-exercise VO2 and muscle use reveals, a significant reduction in end-exercise VO2, due to an attenuated Vo2 slow component. The results suggest that the relative metabolic stress of the vastus lateralis was reduced after training.
