简要总结
The purpose of this study is to examine the effects of a pre-workout dietary supplement during resistance training on training adaptations.
详细描述
A number of nutritional strategies have been developed to optimize nutrient delivery prior to exercise. This includes providing carbohydrate and a number of ergogenic nutrients prior to, during and/or following exercise. As a result, a number of pre-workout supplements have been developed to increase energy availability, promote vasodilation and/or positively affect exercise capacity. The purpose of this study is to investigate the effects of ingesting a pre-workout dietary supplement during resistance training on training adaptations.
