Effects of Four-Week Rhodiola Rosea Supplementation on Physical Fitness, Neuromuscular Performance, and Decision-Making in Competitive Football Players

Effects of Four-Week Rhodiola Rosea Supplementation on Physical Fitness, Neuromuscular Performance and Decision-Making in Competitive Football Players: A Randomised Controlled Trial

This study investigates whether four weeks of Rhodiola rosea supplementation can improve physical fitness, neuromuscular performance, and decision-making ability in competitive male football players. Participants are randomly assigned to receive either Rhodiola rosea or a placebo while continuing their regular football training. Before and after the four-week intervention, all participants complete a series of tests, including aerobic fitness, repeated sprint ability, jumping performance, reaction time, and soccer-specific decision-making tasks. Blood samples are also collected to assess fatigue and recovery-related markers. The purpose of this study is to determine whether Rhodiola rosea supplementation can enhance performance and cognitive function under high-intensity training and competition conditions.

This study is a prospective, double-blind supplementation study conducted in competitive male football players to examine the effects of short-term Rhodiola rosea intake on physical and cognitive performance under regular training conditions.

Participants continue their habitual football training while receiving either Rhodiola rosea supplementation or a placebo for four weeks. Performance assessments are conducted before and after the intervention period under standardized conditions.

The study aims to explore whether Rhodiola rosea supplementation may support adaptations related to high-intensity exercise performance, neuromuscular function, and decision-making ability in competitive football players.
