Abstract

Background

Although several studies have evaluated the effect of coffee on sports performance, the effect of caffeine on sports performance during fatigue status remains unclear.

Objectives

This study aimed to determine the effect of high and low doses of coffee on the repeated sprint test (RST), perceived fatigue (PF), and eye–hand coordination following physical fatigue status in male basketball players.

Methods

Twenty-four male basketball players were randomly placed in 4 conditions including 1) low-dose espresso coffee (LDEC); 2) high-dose espresso coffee (HDEC); 3) decaffeinated espresso coffee (PLA); and 4) no drinking (CON). PF and eye–hand coordination were measured using the soda pop test (SPT) at baseline, immediately after the RST, and 5 min after the 10 all-out sprints with a 30-s interval of RST.

Results

The time of the first to tenth sprints (RST₁ to RST₁₀), total time (RST-TT), mean time (RST-MT), best time (RST-BT), and percentage of performance decrement (PD) were recorded. Coffee dose-dependently significantly improved RST-TT, RST-MT, and RST-BT compared with PLA and CON. PF increased significantly in all conditions immediately after RST compared with baseline. Five minutes after RST, PF was reduced compared to immediately after RST. Immediately after RST, coffee reduced PF dose-dependently compared with PLA and CON. SPT decreased immediately after RST in PLA and CON compared with baseline, whereas no significant change was observed for LDEC and HDEC. At baseline and immediately after RST, coffee and placebo consumption increased SPT performance compared with CON. Immediately and 5 min after RST, coffee increased SPT performance compared to PLA dose-dependently.

Conclusions

HDEC and LDEC improved RST performance and eye–hand coordination in male basketball players. However, HDEC showed a more profound effect compared with LDEC.

低剂量和高剂量浓缩咖啡可提高男子篮球运动员疲劳状态下的重复冲刺表现和眼手协调能力

本研究旨在确定高剂量和低剂量咖啡对男性篮球运动员身体疲劳状态下重复冲刺测试（RST）、感知疲劳（PF）和眼手协调能力的影响。方法24名男性篮球运动员被随机置于4种条件下，包括1）低剂量意式浓缩咖啡（LDEC）；2）高剂量意式浓缩咖啡（HDEC）；3）无咖啡因意式浓缩咖啡（PLA）；4）不饮用（CON）。结果记录了第一次至第十次冲刺的时间（RST1 至 RST10）、总时间（RST-TT）、平均时间（RST-MT）、最佳时间（RST-BT）和成绩下降百分比（PD）。与 PLA 和 CON 相比，咖啡剂量依赖性地明显改善了 RST-TT、RST-MT 和 RST-BT。与基线相比，在 RST 结束后，所有条件下的 PF 都明显增加。RST 5 分钟后，PF 与 RST 刚结束时相比有所降低。与 PLA 和 CON 相比，RST 后咖啡立即降低了 PF 的剂量依赖性。与基线相比，PLA 和 CON 在 RST 后立即降低了 SPT，而 LDEC 和 HDEC 则无明显变化。与 CON 相比，在基线和 RST 后立即饮用咖啡和安慰剂可提高 SPT 性能。结论HDEC 和 LDEC 改善了男性篮球运动员的 RST 表现和眼手协调能力。然而，与 LDEC 相比，HDEC 的效果更显著。
