Full description

The aim of our study was to determine the acute effects of commercially available multi-ingredient pre-workout supple-ment (MIPS) containing: beta-alanine, taurine, caffeine, L-tyrosine, and cayenne pepper (capsai-cin) on physical performance in untrained men. The aerobic and anaerobic capacity was determined after ingestion of MIPS. A randomized, crossover, single-blind design was used to evaluate the effects of the dietary supplement on physical performance. The participants performed the exercise test twice, in random order: as a control test and after supplement administration (MIPS). The measurements took place over two consecutive days. Somatic measurements were taken on the same day that the first all-out test was performed. Twelve young healthy men, without medical contraindications to supramaximal and maximal intensity exercise, participated in the study. The exercise tests took place under medical supervision.
