There is limited evidence regarding the effect of circuit-type low-intensity resistance exercise on physical fitness and blood parameters in breast cancer survivors (BCSs). Therefore, this study aimed to investigate the effect of low-intensity circuit resistance exercise on changes in physical fitness and blood parameters in BCSs. A total of 16 BCSs participated in a low-intensity circuit resistance exercise group (LCREG). The exercise program in the LCREG consisted of 50-60% of one repetition maximum, two to three times weekly, for 24 weeks. The control group (CG) did not receive any interventions. All participants were measured for physical fitness and blood parameters before and after the exercise intervention. The results showed that LCREG significantly improved body mass index (BMI) ( = 0.012), grip strength ( = 0.017), back strength ( = 0.042), plank ( = 0.036), balance ( = 0.030), low-density lipoproteins (LDL) ( = 0.050), total cholesterol ( = 0.017), and natural killer cell activity (NKCA) ( = 0.035) after exercise compared to before exercise. The LCREG also significantly improved BMI ( = 0.001), grip strength ( = 0.014), plank ( = 0.018), balance ( = 0.012), LDL ( = 0.024), total cholesterol ( = 0.012), and NKCA ( = 0.036) compared to the CG. These findings suggest that low-intensity circuit resistance exercise can increase physical fitness levels and improve the blood index in BCSs.
关于循环式低强度抗阻运动对乳腺癌幸存者（BCS）体能和血液参数的影响，现有证据有限。因此，本研究旨在探讨低强度循环抗阻运动对BCS体能和血液参数变化的影响。共有16名BCS参加了低强度循环抗阻运动组（LCREG）。LCREG的运动方案包括一次最大重复量的50%-60%，每周进行两到三次，共24周。对照组（CG）未接受任何干预。所有参与者在运动干预前后均进行了体能和血液参数测量。结果显示，与运动前相比，LCREG运动后显著改善了体重指数（BMI）（P = 0.012）、握力（P = 0.017）、背部力量（P = 0.042）、平板支撑（P = 0.036）、平衡能力（P = 0.030）、低密度脂蛋白（LDL）（P = 0.050）、总胆固醇（P = 0.017）和自然杀伤细胞活性（NKCA）（P = 0.035）。与CG相比，LCREG还显著改善了BMI（P = 0.001）、握力（P = 0.014）、平板支撑（P = 0.018）、平衡能力（P = 0.012）、LDL（P = 0.024）、总胆固醇（P = 0.012）和NKCA（P = 0.036）。这些发现表明，低强度循环抗阻运动可以提高BCS的体能水平并改善血液指标。
