Overview

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

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.

The participants performed the exercise twice, in random order: as a control test and after supplement administration. The acute effects of MIPS supplementation (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)) on aerobic and anaerobic performance were evaluated in untrained men

Outcomes

Primary Outcomes

anaerobic power

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.

Time frame: one day every 30 minutes

aerobic power

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.

Time frame: one day every 30 minutes
