Summary

This study aims to investigate the acute effects of Tribulus terrestris supplementation on anaerobic performance and sprint times in trained male combat sport athletes. A total of 28 athletes from kickboxing, Muay Thai, and taekwondo disciplines will participate in a randomized, double-blind, placebo-controlled, crossover trial.

Participants will ingest either a single oral dose of 625 mg Tribulus terrestris (40% saponins) or a placebo 60 minutes before performing performance tests. The performance assessments will include a 30-second Wingate anaerobic cycling test and 20 m and 100 m sprint tests using photocell timing gates. After a wash-out period, participants will cross over to the alternate condition.

The primary outcomes are peak power and mean power from the Wingate test and sprint times over 20 m and 100 m.
