本研究旨在探讨市售能量饮料对青少年篮球运动员投篮准确性、跳跃能力和耐力的影响。16名年轻的篮球运动员（一级联赛; 14.9 +/- A 0.8岁; 73.4 +/- A 12.4公斤; 182.3 +/- A 6.5厘米）自愿参加研究。他们摄入（a）每公斤体重含有3毫克咖啡因的能量饮料或（B）具有相同外观和味道的安慰剂能量饮料。经过60分钟的咖啡因吸收后，他们进行了罚球投篮和三分球投篮测试。之后，参与者进行了最大反向运动跳跃（CMJ），重复最大跳跃测试15秒（RJ-15），和溜溜球间歇性恢复测试1级（溜溜球IR 1）。在检测前和检测后30 min采集尿样。与安慰剂相比，摄入含咖啡因的能量饮料不会影响罚球的准确性（咖啡因= 70.7 +/- A 11.8% vs安慰剂= 70.3 +/- A 11.0%; P = 0.45），三点射击测试（39.9 +/- A 11.8 vs 38.1 +/- A 12.8%; P = 0.33）或Yo-Yo IR 1覆盖的距离（2，000 +/- A 706 vs 1，925 +/- A 702 m; P = 0.19）。然而，在CMJ期间，能量饮料显著增加了跳跃高度（38.3 +/- A 4.4 vs 37.5 +/- A 4.4 cm; P < 0.05）RJ-15期间的平均跳跃高度（30.2 +/-A3.6 vs 28.8 +/-A3.4 cm; P < 0.05）和尿咖啡因排泄量（1.2 +/-A0.7 vs 0.1 +/-A0.1 μ g/mL; P < 0.05）。摄入含咖啡因的能量饮料（3 mg/kg体重）增加了跳跃性能，但不影响篮球投篮精度。
This study aimed at investigating the effects of a commercially available energy drink on shooting precision, jump performance and endurance capacity in young basketball players. Sixteen young basketball players (first division of a junior national league; 14.9 +/- A 0.8 years; 73.4 +/- A 12.4 kg; 182.3 +/- A 6.5 cm) volunteered to participate in the research. They ingested either (a) an energy drink that contained 3 mg of caffeine per kg of body weight or (b) a placebo energy drink with the same appearance and taste. After 60 min for caffeine absorption, they performed free throw shooting and three-point shooting tests. After that, participants performed a maximal countermovement jump (CMJ), a repeated maximal jumps test for 15 s (RJ-15), and the Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1). Urine samples were obtained before and 30 min after testing. In comparison to the placebo, the ingestion of the caffeinated energy drink did not affect precision during the free throws (Caffeine = 70.7 +/- A 11.8 % vs placebo = 70.3 +/- A 11.0 %; P = 0.45), the three-point shooting test (39.9 +/- A 11.8 vs 38.1 +/- A 12.8 %; P = 0.33) or the distance covered in the Yo-Yo IR1 (2,000 +/- A 706 vs 1,925 +/- A 702 m; P = 0.19). However, the energy drink significantly increased jump height during the CMJ (38.3 +/- A 4.4 vs 37.5 +/- A 4.4 cm; P < 0.05) mean jump height during the RJ-15 (30.2 +/- A 3.6 vs 28.8 +/- A 3.4 cm; P < 0.05) and the excretion of urinary caffeine (1.2 +/- A 0.7 vs 0.1 +/- A 0.1 mu g/mL; P < 0.05). The intake of a caffeine-containing energy drink (3 mg/kg body weight) increased jump performance although it did not affect basketball shooting precision.
