- Brief Summary
The aim of the study was to determine the acute effects of multi-ingredient pre-workout supple-ment (MIPS) containing: beta-alanine, taurine, caffeine, L-tyrosine, and cayenne pepper (capsaicin) on physical performance in untrained men
- Detailed 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.

Group Intervention Description group with MIPS supplementation multi-ingredient pre-workout dietary supplement (caffeine-based) 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.
- Primary Outcome Measures
Name Time Method anaerobic power one day every 30 minutes Anaerobic power (anaerobic capacity) was determined twice (pre and post) dietary supplementation on one day. The anaerobic test was performed before supplemenation and 30 minutes after.
aerobic power one day every 30 minutes Aerobic power (aerobic capacity) was determined twice (pre and post) dietary supplementation on one day. The anaerobic test was performed before supplemenation and 30 minutes after.
