急性运动有益于认知，一些证据表明脑源性神经营养因子（BDNF）在这种效应中发挥作用。本研究旨在探讨运动强度、记忆力与脑源性神经营养因子（BDNF）的量效关系。年轻人完成了3次相对于呼吸机阈值（Vt）的不同强度的运动（VO 2 max，Vt-20%，Vt + 20%）。每次训练，参与者锻炼约30分钟。锻炼后，他们进行雷伊听觉语言学习测试（RAVLT），以评估短期记忆，学习和长期记忆回忆。24小时后，他们完成了RAVLT识别试验，该试验提供了另一种长期记忆的测量方法。在运动前、运动后立即和30分钟回忆测试后抽血。结果表明，24小时延迟后评估的长期记忆作为运动强度的函数而不同，最大强度运动后观察到的益处最大。BDNF数据显示，运动反应显着增加;然而，相对于运动强度没有差异，BDNF和记忆之间没有显着关联。未来的研究是必要的，这样我们就可以更好地了解如何使用运动来提高认知能力。
Acute exercise benefits cognition, and some evidence suggests that brain-derived neurotrophic factor (BDNF) plays a role in this effect. The purpose of this study was to explore the dose response relationship between exercise intensity, memory, and BDNF. Young adults completed 3 exercise sessions at different intensities relative to ventilator threshold (Vt) (VO2max, Vt-20%, Vt + 20%). For each session, participants exercised for approximately 30 min. Following exercise, they performed the Rey Auditory Verbal Learning Test (RAVLT) to assess short-term memory, learning, and long-term memory recall. Twenty-four hours later, they completed the RAVLT recognition trial, which provided another measure of long-term memory. Blood was drawn before exercise, immediately postexercise, and after the 30-min recall test. Results indicated that long-term memory as assessed after the 24-hr delay differed as a function of exercise intensity with the largest benefits observed following maximal intensity exercise. BDNF data showed a significant increase in response to exercise; however, there were no differences relative to exercise intensity and there were no significant associations between BDNF and memory. Future research is warranted so that we can better understand how to use exercise to benefit cognitive performance.
