The use of caffeine-containing (74-mg) energy patches (EnP) offers a novel mode of caffeine delivery that may alleviate stomach discomfort associated with oral caffeine use. The purpose of this study was to use four separate tests to evaluate the effects of EnP use on aerobic and anaerobic exercise performance. Three separate moderately active college-aged sample populations performed either 1) cycle time-to-exhaustion, 2) Wingate (WIN), or 3) repeated sprints and one repetition maximum bench press using EnP and placebo patches (PlP). No statistical differences were found between EnP and PlP for all dependent variables (p > 0.05) except for WIN peak power, …

Energy drinks are widely available and popular among athletes and non-athletes. However, the effects of energy drinks on resting and exercise energy expenditure and metabolism remain largely unknown. On four separate occasions, baseline measurements of resting metabolic rate (RMR) and Respiratory Exchange Ratio (RER) were obtained in ten healthy males (21.4 ± 1.6 y, 77.60± 7.5 kg, 180.0 ± 7.1 cm). Then, in a randomly assigned cross-over design, the subjects consumed 473 ml of one of three commercially available energy drinks or a placebo and then RMR and RER were measured 1 hour later. The subjects then engaged in 15 …
