To evaluate the effects of brain endurance training (BET) on endurance and cognitive performance in road cyclists.
Two independent randomized controlled pretest-posttest training studies.
In both studies cyclists trained five times/week for six weeks and completed either cognitive response inhibition tasks (Post-BET group) or listened to neutral sounds (control group) after each training session. In Study-1, 26 cyclists performed a time to exhaustion (TTE) test at 80 % peak power output (PPO), followed by a 30-min Stroop task, and a TTE test at 65 % PPO. In Study-2, 24 cyclists performed a 5-min time trial, followed by a 30-min Stroop task, 60-min submaximal incremental test, and a 20-min . Heart rate, lactate, rating of perceived exertion (RPE), Stroop reaction time and accuracy were also measured.
During Study 1, Post-BET improved TTE at 80 % (p = 0.032) and 65 % PPO (p = 0.011) significantly more than control with lower RPE (all p < 0.043). In Study 2, 5-min TT performance did not differ between groups. During the 60-min submaximal incremental test, RPE was lower in the Post-BET group compared to the control group (p = 0.034) and 20-min TT performance improved significantly more in the Post-BET group than in the control group (all p < 0.031). No group differences were found in physiological measures. In both studies, Stroop reaction times improved significantly more in the Post-BET group than in the control group (all p < 0.033).
These findings suggest that Post-BET may be used to improve the performance of road cyclists.
评估脑耐力训练（BET）对公路自行车手耐力和认知表现的影响。
两项独立的随机对照预测试后训练研究。
在两项研究中，自行车手每周训练 5 次，持续 6 周，并且在每次训练后完成认知反应抑制任务（Post-BET 组）或听中性声音（对照组）。在研究 1 中，26 名自行车手在 80%峰值功率输出（PPO）下进行了耐力测试（TTE），然后进行了 30 分钟的斯特鲁普任务，然后在 65%PPO 下进行了 TTE 测试。在研究 2 中，24 名自行车手进行了 5 分钟计时赛，然后进行了 30 分钟的斯特鲁普任务、60 分钟亚最大递增测试和 20 分钟的测试。心率、乳酸、感知用力评分（RPE）、斯特鲁普反应时间和准确性也进行了测量。
在研究 1 中，Post-BET 在 80%（p=0.032）和 65%PPO（p=0.011）时的 TTE 显著改善，比对照组的 RPE 低（均 p<0.043）。在研究 2 中，两组 5 分钟 TT 表现无差异。在 60 分钟亚最大递增测试中，Post-BET 组的 RPE 低于对照组（p=0.034），Post-BET 组的 20 分钟 TT 表现显著改善，优于对照组（均 p<0.031）。两组在生理测量方面没有差异。在两项研究中，Post-BET 组的斯特鲁普反应时间均显著改善，优于对照组（均 p<0.033）。
这些发现表明，Post-BET 可能用于提高公路自行车手的表现。
