Sixty minutes following beverage ingestion, each participant completed 10-to-100% 1RM power-load tests for the bench press and half-squat. Ingestion of the ED with 1 mg·kgBM-1of caffeine was not enough to raise the power output during the power-load tests. However, the ingestion of an ED with 3 mg·kgBM-1of caffeine increased maximal power output by 7% in both the half-squat and bench-press as compared to the ingestion of a placebo . A recent study by Gonzalez and colleagues
 indicated that an energy matrix consisting of caffeine, taurine and glucoronolactone consumed 10-min prior to a workout resulted in an 11.9% improvement (p < 0.05) in the number of repetitions performed during 4 sets of the squat or bench press exercise using 80% DMXAA of the subject’s 1-RM. In addition, the average power output for the workout was significantly higher for subjects consuming the energy drink compared to subjects consuming the placebo. In addition to resistance and high intensity anaerobic exercise, the effects that ED exert on speed/agility performance has also been investigated. Collegiate female soccer players ingested an ED containing
1.3 mg·kgBM-1of caffeine and 1 gram of taurine or a caffeine and taurine-free placebo 60 minutes prior to repeated agility t-tests . No difference in agility t-test performance Lonafarnib molecular weight between the ED and placebo groups was reported. Specifically, the highest difference reported between the two groups was during the third set of eight agility t-tests, and the difference reached only 1.15% between the groups. It is unlikely that the carbohydrate content alone in ED is responsible for improvements in resistance exercise performance. In support of this view, the majority of studies in which supplemental carbohydrate was ingested prior to a resistance-training bout did not report improvements in resistance training performance [176–178]. Conclusion ED (containing approximately 2 mg·kgBM-1caffeine) consumed 45 to 60 minutes prior to anaerobic/resistance exercise may improve upper- and lower- body total lifting volume, but has no effect on repeated high intensity sprint exercise, or on agility performance.
Ingestion prior to endurance exercise Several studies have investigated the effects of ED ingestion prior to aerobic exercise [62, 170–172, 179]. In the earliest of these studies, Inositol monophosphatase 1 Alford and colleagues  investigated the effects of ingesting a Fludarabine chemical structure commercial ED on aerobic endurance. In a repeated measures, crossover design, young healthy participants ingested 250 mL of a commercial ED (containing 80 mg of caffeine and 26 grams of carbohydrate), a carbonated water beverage, or no beverage at all 30 minutes prior to performing an endurance exercise bout. Test days for separate treatments were assessed within a week. Aerobic performance was analyzed by the amount of time that exercise could be maintained at 65-75% of maximum heart rate on a cycle ergometer.
