This study is a double-blind, randomized, placebo-controlled trial designed to examine whether 8 weeks of Cistanche deserticola supplementation, when combined with a standardized anaerobic training program, can improve anaerobic exercise performance, recovery, and selected body composition outcomes in young adult men with different athletic training levels.
Participants will be assigned to receive either Cistanche deserticola extract or a matched placebo while completing the same supervised anaerobic training program. The study will assess changes in anaerobic performance, including Wingate test outcomes and jump performance, as well as recovery-related indicators such as blood lactate, creatine kinase, malondialdehyde, testosterone, cortisol, and the testosterone-to-cortisol ratio. Body composition outcomes, including body fat percentage and skeletal muscle mass, will also be evaluated.
The purpose of this study is to determine whether Cistanche deserticola supplementation provides additional benefits beyond training alone, and whether these effects differ between highly trained and recreationally trained participants.
