2023-05-09T08:10:03Z urn:hdl:10324/59543 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 Fernández Lázaro, Diego Mielgo Ayuso, Juan Francisco Valle Soto, Miguel del Adams, David P. González Bernal, Jerónimo J. Seco Calvo, Jesús Farmacología Biología Entrenamiento (Deportes) Producción Científica 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. 2023-05-09T08:10:03Z 2023-05-09T08:10:03Z 2021 info:eu-repo/semantics/article Nutrients, 2021, vol.13, n. 11, 3969 https://uvadoc.uva.es/handle/10324/59543 10.3390/nu13113969 3969 11 Nutrients 13 2072-6643 eng https://www.mdpi.com/2072-6643/13/11/3969 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2021 The Authors Atribución 4.0 Internacional MDPI
