Brief Summary

The purpose of this study is to investigate whether β-caryophyllene supplementation can enhance the static apnea capacity of freedivers.

Detailed Description

Using a randomized crossover design with double-blind methodology, participants were assigned to either the β-caryophyllene trial (BCP) trial or the placebo (PLA) trial, which without β-caryophyllene. Participants consumed either 200 mg of β-caryophyllene capsules (BCP trial) or placebo capsules (PLA trial) based on pre-test results. After a 30-minute rest period and warm-up, a single maximal voluntary static breath-hold test was conducted. Breath-hold duration and physiological and salivary biochemical indicators before and after the breath-hold test were observed.
