To examine the changes in obesity-related hormones and metabolic syndrome markers in male high school students with obesity following a weekend-focused moderate- or high-intensity exercise program at the recommended weekly physical activity level, or a program of regular exercise 3 times a week at moderate intensity, over a 10-week period. Forty-eight male high school students who were obese with a body fat percentage of ≥25% were randomly assigned to one of three groups: a regular moderate-intensity exercise group (n=17) that freely selected and performed moderate-intensity aerobic and resistance training exercises, every Monday, Wednesday, and Friday, for a total of 150-300 min/wk; a weekend-focused moderate-intensity exercise group (n=15) that freely selected and performed aerobic and resistance training exercises every Saturday for 150-300 min; and a week-end-focused high-intensity exercise group (n=16) that freely selected and performed aerobic and resistance training exercises every Sunday for 75-150 min. Insulin and leptin levels significantly decreased in all the groups, with the greatest reduction in the regular exercise group. Abdominal circumference and triglyceride levels significantly decreased in all the groups. Fasting glucose decreased only in the regular exercise group. High-density lipoprotein cholesterol significantly increased in both the regular and weekend-focused moderate-intensity exercise groups. No significant differences in adiponectin levels, and systolic and diastolic blood pressure were observed between the groups. A weekend-focused exercise program has health effects similar to those of regular exercise, highlighting the importance of meeting the recommended weekly physical activity levels.
为研究肥胖的男性高中生在10周时间内，遵循推荐的每周体育活动量进行以周末为重点的中等强度或高强度锻炼计划，或每周进行3次中等强度的常规锻炼计划后，与肥胖相关的激素和代谢综合征标志物的变化。48名肥胖的男性高中生，体脂百分比≥25%，被随机分为三组：常规中等强度锻炼组（n = 17），每周一、三、五自由选择并进行中等强度的有氧和阻力训练运动，总计150 - 300分钟/周；以周末为重点的中等强度锻炼组（n = 15），每周六自由选择并进行有氧和阻力训练运动150 - 300分钟；以周末为重点的高强度锻炼组（n = 16），每周日自由选择并进行有氧和阻力训练运动75 - 150分钟。所有组的胰岛素和瘦素水平均显著下降，常规锻炼组下降幅度最大。所有组的腹围和甘油三酯水平均显著下降。仅常规锻炼组的空腹血糖下降。常规锻炼组和以周末为重点的中等强度锻炼组的高密度脂蛋白胆固醇均显著升高。各组之间脂联素水平以及收缩压和舒张压无显著差异。以周末为重点的锻炼计划与常规锻炼具有相似的健康效果，凸显了达到推荐的每周体育活动量的重要性。
