Nicotine is beneficial to mood, arousal and cognition in humans. Due to the importance of cognitive functioning for archery athletes, we investigated the effects of nicotine supplementation on the cognitive abilities, heart rate variability (HRV), and sport performance of professional archers.
Eleven college archers were recruited and given 2 mg of nicotine supplementation (NIC group) and placebo (PLA group) in a crossover design.
The results showed that at 30 min after the intake of nicotine gum, the "correct rejection" time in the NIC group was significantly lower than that of the PLA group (7.29 ± 0.87 vs. 8.23 ± 0.98 msec, p < 0.05). In addition, the NIC group completed the grooved pegboard test in a shorter time than the PLA group (48.76 ± 3.18 vs. 53.41 ± 4.05 s, p < 0.05), whereas motor reaction times were not different between the two groups. Saliva α-amylase activity was significantly lower after nicotine supplementation (p < 0.01) but increased immediately after the archery test in the NIC group (p < 0.05). In addition, nicotine supplementation significantly decreased HRV and increased the archery score (290.58 ± 10.09 vs. 298.05 ± 8.56, p < 0.01).
Nicotine enhances the performance of archery athletes by increasing cognitive function and stimulating the sympathetic adrenergic system.
尼古丁对人类的情绪、觉醒和认知有益。由于认知功能对射箭运动员的重要性，我们研究了尼古丁补充对专业射箭运动员的认知能力、心率变异性（HRV）和运动表现的影响。
招募了 11 名大学生射箭运动员，采用交叉设计给予他们 2 毫克尼古丁补充剂（NIC 组）和安慰剂（PLA 组）。
结果表明，在摄入尼古丁口香糖 30 分钟后，NIC 组的“正确拒绝”时间明显低于 PLA 组（7.29±0.87 与 8.23±0.98 毫秒，p<0.05）。此外，NIC 组完成凹槽钉板测试的时间短于 PLA 组（48.76±0.38 与 53.41±0.40 秒，p<0.05），而两组的运动反应时间没有差异。唾液 α-淀粉酶活性在尼古丁补充后明显降低（p<0.01），但在 NIC 组的射箭测试后立即增加（p<0.05）。此外，尼古丁补充显著降低 HRV 并增加射箭得分（290.58±10.09 与 298.05±8.56，p<0.01）。
尼古丁通过提高认知功能和刺激交感肾上腺素能系统来提高射箭运动员的表现。
