标题：The Effects of 6 Weeks of Tribulus terrestris L. Supplementation on Body Composition, Hormonal Response, Perceived Exertion, and CrossFit ® Performance: A Randomized, Single-Blind, Placebo-Controlled Study
摘要：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 ® endurance is limited. This study aimed to determine whether TT supplementation improve body composition, hormonal response, and performance among CrossFit ® athletes. In a randomized, single-blind, placebo-controlled trial, a total of 30 healthy CrossFit ®-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 ® performance (5 common Workouts of the Day: back squat, bench press, dead lift, Grace, and CrossFit ® 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 ® male athletes. However, TT supplementation may act as a testosterone booster helping the recovery after physical loads and mitigating fatigue.
