Brief Summary

Basketball is a popular team sport where athletes score points by successfully shooting the ball into the basket. Accuracy in shooting is crucial for players to score points effectively. Pre-workout supplements (PWS) have garnered interest from athletes and fitness enthusiasts due to the purported synergistic action of their ingredients which, when consumed before training, may help improve athletic performance. The acute effect of PWS or similar on the shooting accuracy of basketball athletes has not yet been investigated. Therefore, this study aimed to investigate the acute effect of a caffeine-based PWS (containing caffeine, creatine, β-alanine, citrulline malate, and BCAAs) on the stationary free throw, two-point, and three-point shooting accuracy in basketball players.

Outcome Measures

Primary Outcomes (3)

• The stationary free-throw shooting test

  Each player will complete three sets of ten free throws, with a three-minute rest between sets. Two other players will stood under the hoop and pass the ball to the shooter.

  At baseline (no supplement), 30 minutes after placebo ingestion, and 30 minutes after PWS ingestion

• The stationary two-point shooting test

  Each athlete should execute two stationary two-point shots from five different positions, a total of ten shots. Two other players will collect the ball and return it to the shooter. This procedure will be repeated three times, with three minutes rest between each round, resulting in a total of 30 shots. The average successful scoring percentage from the three trials will used for analysis.

  At baseline (no supplement), 30 minutes after placebo ingestion, and 30 minutes after PWS ingestion

• The stationary three-point shooting test

  Each athlete should execute two stationary three-point shots from five different positions placed 6.75 meters, a total of ten shots. Two other players will collect the ball and return it to the shooter. This procedure will be repeated three times, with three minutes rest between each round, resulting in a total of 30 shots. The average successful scoring percentage from the three trials will used for analysis.

  At baseline (no supplement), 30 minutes after placebo ingestion, and 30 minutes after PWS ingestion
