摘要

本研究调查了摄入咖啡因(3 毫克/千克体重)的时机对篮球运动模拟测试(BEST)中三分球投篮准确性和其他表现参数的影响。18 名大学篮球运动员(平均值 ± SD:年龄 = 24.4 ± 1.5 岁,身高 = 181.7 ± 9.5 厘米,体重 = 80.9 ± 13.2 千克)按照随机顺序接受了一次熟悉试验和三种主要条件:(a) 安慰剂(麦芽糊精)和安慰剂,(b) 咖啡因和安慰剂,以及 (c) 安慰剂和咖啡因。参与者在进行四节 BEST 和三分投篮训练前 75 分钟和 15 分钟分别服用安慰剂或咖啡因药片。在每节比赛中,参赛者完成 16 轮 BEST 和 10 次三分球投篮。对垂直跳跃高度、6 米冲刺时间、BEST 完成时间、三分投篮准确率、心率、感觉消耗率、血糖、血乳酸以及与成绩有关的心理测量进行了测量。BEST完成时间在不同条件下存在差异(安慰剂和安慰剂=26.4 ± 2.0秒,咖啡因和安慰剂=25.8 ± 2.0秒,安慰剂和咖啡因=25.9 ± 2.1秒;p = .031),但三分球投篮准确率(安慰剂和安慰剂=12.33 ± 4.10;咖啡因和安慰剂=12.61 ± 2.81;安慰剂和咖啡因=11.67 ± 3.77;p = .648)、垂直跳跃高度或冲刺时间不存在差异。控制摄入咖啡因的时间并不能提高三分球投篮的准确性、纵跳高度或6米冲刺时间,但咖啡因可以提高模拟篮球运动中的表现时间,而与摄入时间无关。

Timing of Caffeine Ingestion Does Not Improve Three-Point Shooting Accuracy in College Basketball Players.

This study investigated the effects of the timing of caffeine (3 mg/kg body mass) ingestion on three-point shooting accuracy and other performance parameters during a basketball exercise simulation test (BEST). Eighteen college basketball players (mean ± SD: age = 24.4 ± 1.5 years, height = 181.7 ± 9.5 cm, body mass = 80.9 ± 13.2 kg) underwent one familiarization trial and three main conditions in a randomized order: (a) placebo (maltodextrin) and placebo, (b) caffeine and placebo, and (c) placebo and caffeine. Participants ingested either the placebo or caffeine pill 75 and 15 min before performing four quarters of the BEST and a three-point shooting protocol. During each quarter, participants completed 16 rounds of the BEST and ten three-point shots. Vertical jump height, 6 m sprint timing, BEST completion timing, three-point shooting accuracy, heart rate, rate of perceived exertion, blood glucose, blood lactate, and psychological measures pertaining to performance were measured. The BEST completion timing differed among conditions (placebo and placebo = 26.4 ± 2.0 s, caffeine and placebo = 25.8 ± 2.0 s, placebo and caffeine = 25.9 ± 2.1 s; p = .031) but not three-point shooting accuracy (placebo and placebo = 12.33 ± 4.10; caffeine and placebo = 12.61 ± 2.81; placebo and caffeine = 11.67 ± 3.77; p = .648), vertical jump height, or sprint times. Manipulating ingestion timing of caffeine did not improve three-point shooting accuracy, vertical jump height, or 6 m sprint timings, but caffeine can improve performance times during simulated basketball exercise irrespective of ingestion timing.
