TT supplementation did not improve performance or body composition in CrossFit(R) male athletes, but may serve as a testosterone booster to aid recovery and reduce fatigue after exercise.
Tribulus terrestris L. (TT) supplementation have been shown to enhance sports performance in many but not all studies. Moreover, data regarding the potential impact of TT supplementation on CrossFit (R) endurance is limited. This study aimed to determine whether TT supplementation improve body composition, hormonal response, and performance among CrossFit (R) athletes. In a randomized, single-blind, placebo-controlled trial, a total of 30 healthy CrossFit (R)-trained males were randomly allocated to receive either 770 mg of TT supplementation or a placebo daily for 6 weeks. Body mass, fat mass, fat composition, testosterone and cortisol levels, and CrossFit (R) performance (5 common Workouts of the Day: back squat, bench press, dead lift, Grace, and CrossFit (R) Total) were assessed before and after intervention. There were no significant group x time interactions for the outcomes of the study except for testosterone levels and bench press performance (p < 0.05). TT supplementation did not impact enhance performance or body composition in CrossFit (R) male athletes. However, TT supplementation may act as a testosterone booster helping the recovery after physical loads and mitigating fatigue.
