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.

Experimental group

Description:

Group with supplementation. Supplement was commercially available and dispensed without a prescription. The dietary supplement contained in one dose (30ml): beta-alanine 3000 mg, taurine 1000 mg, caffeine 290 mg, L-tyrosine 125 mg, and cayenne pepper extract (Capsicum annuum L.) 4.2 mg (of which 8% capsaicin). The supplement was mixed with water; in total, participants were given 100 ml of liquid to drink, 30 minutes before the warm-up for the all-out anaerobic test.
