It is likely that the participants in the SUP group would have seen a significant ergogenic benefit (click here improved Selleckchem Y-27632 LPM) related to the supplement and training protocol after an extended supplementation period. Data from another study investigated performance variables as well as body composition effects of the same commercially available product used in the current study but with an eight week supplementation period [14]. Results support the conclusions and findings of the present study (improved strength and anaerobic power), suggesting long-term use may have greater benefits. The time delay in measurable results between these two

studies reiterates the need for analyses of longer duration on pre-workout supplements as well as acute studies to determine how quickly supplement benefits can be realized.

The lack of a crossover design is one limitation to this study. Future acute research may investigate the effects of the proprietary supplement in a crossover manner to gain further knowledge of the potential for improved performance and/or body composition. A crossover study using the supplement used in the present study would also provide higher quality side-effect information. Conclusions It may be beneficial for resistance trained males to consume a proprietary pre-workout supplement containing beta-alanine, creatine, BCAAs, and caffeine when wanting to improve GSK3235025 cost lower body strength. It seems likely, based on the available research, that taking the pre-workout supplement for an extended period of time in combination with exercise is safe and can lead to beneficial changes in strength and body composition.
