To verify the combined and isolated effects of alcohol consumption and one night of sleep deprivation on maximal strength, muscle endurance and aerobic performance. Also, to verify the association between perceived fatigue and exercise performance. Ten male participants were randomized into four conditions: (1) placebo consumption + normal sleep (PLA + SLE); (2) alcohol consumption + normal sleep (ALC + SLE); (3) placebo consumption + sleep deprivation (PLA + SDP), and (4) alcohol consumption + sleep deprivation (ALC + SDP). In each condition, participants ingested 1 g of alcohol per kg of body mass of alcoholic beer or non-alcoholic beer (placebo, 0% of alcohol), followed by one night of normal sleep or sleep deprivation. In the next morning, hangover symptoms, maximal strength, and time to exhaustion during muscle endurance test for elbow flexors (TTE_EF) were performed concurrently to biceps brachii activation. Finally, participants performed a time to exhaustion aerobic test (TTE_AER) on a treadmill with heart rate (HR) and perceived exertion (RPE) assessments. Fatigue and total symptoms of hangover were higher in ALC + SDP compared to PLA + SLE (p = 0.008). No differences were observed between conditions on maximal strength, TTE_EF, TTE_AER, muscle activation, HR and RPE during tests (p > 0.05). Higher perceived fatigue was significantly associated only with shorter TTE_AER (r = − 0.36; p = 0.02). Alcohol consumption, combined or not with total sleep deprivation did not impair maximal strength, muscle endurance and aerobic performance. Higher perceived fatigue seems to impair long-duration activities.

验证饮酒和一晚睡眠不足对最大力量、肌肉耐力和有氧运动表现的综合和孤立影响。此外，验证感知疲劳与运动表现之间的关联。十名男性参与者被随机分为四种情况：（1）服用安慰剂+正常睡眠（PLA+SLE）；（2）饮酒+正常睡眠（ALC+SLE）；(3) 服用安慰剂 + 睡眠剥夺 (PLA + SDP)，以及 (4) 饮酒 + 睡眠剥夺 (ALC + SDP)。在每种情况下，参与者每公斤体重的酒精啤酒或非酒精啤酒（安慰剂，0% 酒精）摄入 1 克酒精，然后一晚正常睡眠或睡眠不足。第二天早上，宿醉症状，最大强度，_EF ) 与肱二头肌激活同时进行。最后，参与者在跑步机上进行了一次疲劳有氧测试 (TTE _AER )，并进行了心率 (HR) 和感知用力 (RPE) 评估。与 PLA + SLE 相比，ALC + SDP 的疲劳和总宿醉症状更高（p  = 0.008）。在测试期间，在最大力量、TTE _EF、 TTE _AER、肌肉激活、HR 和 RPE 的条件之间没有观察到差异（p  > 0.05）。较高的疲劳感仅与较短的 TTE _AER显着相关（r  = − 0.36; p = 0.02）。饮酒，无论是否与完全睡眠剥夺相结合，都不会损害最大力量、肌肉耐力和有氧运动表现。更高的感知疲劳似乎会损害长时间的活动。
