探索性评估高强度运动后部分睡眠限制对年轻男性前额脑电和脉搏血氧指数的影响

Background/Objectives: This exploratory study investigated associations between partial sleep restriction and portable device-derived prefrontal EEG and PPG indices, heart rate recovery (HRR), and perceived exertion (RPE) after high-intensity exercise in young men. Methods: Forty healthy men were randomly assigned to a normal sleep group (NSG; ~8 h, n = 20) or a sleep-restricted group (SRG; ~4 h, n = 20). Participants performed the Harvard Step Test (HST). Prefrontal EEG (Fp1 and Fp2) and single-site PPG were recorded for 1 min before and immediately after exercise using a portable consumer-gr
