NORMAN, Okla.—Consumption of a low-calorie energy drink may improve physiological adaptations to strength training, according to a new study (J Strength Cond Res. 2010;24(8):2227-38. DOI: 10.1519/JSC.0b013e3181aeb0cf). Researchers from the Human Performance Laboratory, Department of Health and Exercise Science at the University of Oklahoma, assessed the effects of daily consumption of an energy drink alone or with exercise on measures of body composition, cardiorespiratory fitness, strength, mood and safety in previously sedentary males. A total of 38 men were recruited for the 10-week study and randomly assigned to energy drink + exercise (EX-A), energy drink (NEX-A), placebo + exercise (EX-B) or placebo (NEX-B). Subjects in the exercise group participated in resistance and endurance exercise.
