Blood flow restriction training (BFRT) is a new method for promoting muscle growth and improving muscle function, even with relatively low-intensity exercise. BFRT on patients with obesity has not been extensively studied. This study aimed to analyze the effects of cycling at 40% of maximum oxygen uptake (VOmax) combined with BFRT on body composition and serum biomarkers among college students with obesity. This pilot study included thirty-seven male college students with obesity aged 18-22 years (experimental group (EG): = 18; control group (CG): = 19). The EG conducted 40% VOmax cycling combined with BFRT activities and the CG conducted 40% VOmax cycling without BFRT two times per week for 12 weeks. Our results showed that in EG, there were significant differences in weight, thigh skinfold thickness (TS), waist circumference, abdominal skinfold thickness, fat mass, body fat percentage, body mass index and glucose (GLU), total cholesterol (TC), triglyceride, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels before and after the experiment ( < 0.05, < 0.01, and < 0.001). After the experiment, TS, GLU, TC, HDL-C, and LDL-C in EG were significantly different than those of the CG ( < 0.05, < 0.01, and < 0.001). Together, our results demonstrate that cycling at 40% VOmax combined with BFRT may improve body composition and blood lipid profile of male college students with obesity. Our findings have important implications for those who cannot perform moderate- and high-intensity exercises.
血流限制训练（BFRT）是一种促进肌肉生长和改善肌肉功能的新方法，即使在低强度运动时也是如此。BFRT 在肥胖患者中的应用尚未得到广泛研究。本研究旨在分析以 40%最大摄氧量（VOmax）进行的自行车运动结合 BFRT 对肥胖大学生的身体成分和血清生物标志物的影响。这项初步研究包括 37 名年龄在 18-22 岁的肥胖男性大学生（实验组（EG）：n=18；对照组（CG）：n=19）。EG 进行了 40%VOmax 自行车运动结合 BFRT 活动，CG 进行了 40%VOmax 自行车运动但不结合 BFRT，每周两次，共 12 周。我们的结果表明，在 EG 中，体重、大腿皮褶厚度（TS）、腰围、腹部皮褶厚度、体脂、体脂百分比、体重指数和血糖（GLU）、总胆固醇（TC）、甘油三酯、低密度脂蛋白胆固醇（LDL-C）和高密度脂蛋白胆固醇（HDL-C）在实验前后均有显著差异（<0.05，<0.01，<0.001）。实验后，EG 中的 TS、GLU、TC、HDL-C 和 LDL-C 与 CG 相比有显著差异（<0.05，<0.01，<0.001）。综上所述，我们的结果表明，以 40%VOmax 进行的自行车运动结合 BFRT 可能改善肥胖男大学生的身体成分和血脂谱。我们的发现对那些无法进行中等强度和高强度运动的人具有重要意义。
