简要总结
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.
详细描述
According to a randomized, double-blind, crossover, research design, 12 active and well-trained male basketball players will be recruited. The sample will participate in three treatments: 1) no supplement; 2) PWS and 3) Placebo (PL). Three field-based basketball shooting tests (stationary free throw, stationary two-point, and three-point shots) will be performed to assess shooting accuracy . During the first visit, participants who met the inclusion criteria will visit our laboratory for health assessment/ screening. At the same time, after receiving a detailed verbal explanation and written instructions from our team's registered nutritionist, participants will be advised to follow the exact same diet one day before the subsequent trials, one week apart. During the second visit, all participants will arrive at the basketball court to execute the shooting tests in the following order: 1) the stationary free throw shooting test (S1P), 2) the stationary two-point shooting test (S2P), and 3) the stationary three-point shooting test (S3P). One week later, during the third visit, all players will return to the same basketball court. They will receive a single dose either PWS or PL 30 minutes prior to the evaluations. Participants and researchers will all blinded as to the type of supplement consumed. Following that, they will complete the same measurements in the same order as in the second visit. A week later all procedures will be repeated, and participants will receive the alternative supplement depending on randomization.

结局指标
主要结局
The stationary free-throw shooting test
时间窗: At baseline (no supplement), 30 minutes after placebo ingestion, and 30 minutes after PWS ingestion
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.
The stationary two-point shooting test
时间窗: At baseline (no supplement), 30 minutes after placebo ingestion, and 30 minutes after PWS ingestion
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.
The stationary three-point shooting test
时间窗: At baseline (no supplement), 30 minutes after placebo ingestion, and 30 minutes after PWS ingestion
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.
