This study examined associations between four health-related physical fitness measures and obesity in Taiwanese youth aged 10-18 years. Data from 13,500 school-aged youth were randomly selected from the "School Physical Fitness Database" of Taiwan by sex and age. Variables examined were height, body mass and performance on modified sit-and-reach (flexibility), bent-leg sit-up (abdominal muscular strength/endurance), standing long jump (lower body explosive strength) and distance run/walk (cardiorespiratory endurance). Adjusted logistic regression analyses were performed. Increased odds of being obese with decreased fitness levels were observed for lower body explosive strength and cardiorespiratory endurance in both sexes. The highest odds of being obese was found in the least fit quintile of cardiorespiratory endurance compared with the most fit quintile both in boys (Odds ratio, OR = 10.44; 95% confidence interval (CI), 7.94-13.73) and girls (OR = 5.40; 95% CI, 3.90-7.47). These findings suggest that in addition to cardiorespiratory fitness, lower body explosive strength is also associated with childhood and adolescent obesity.
本研究考察了四项与健康相关的体能测量指标与台湾 10-18 岁青少年肥胖之间的关联。通过性别和年龄，从台湾的“学校体能数据库”中随机抽取了 13500 名学龄青少年的数据。所检查的变量包括身高、体重以及改良坐立伸展（柔韧性）、屈腿仰卧起坐（腹部肌肉力量/耐力）、立定跳远（下肢爆发力）和长跑/步行（心肺耐力）的表现。进行了调整后的逻辑回归分析。结果显示，在两性中，下肢爆发力和心肺耐力水平下降与肥胖的几率增加有关。与最健康的五分位相比，在男孩（比值比，OR=10.44；95%置信区间（CI），7.94-13.73）和女孩（OR=5.40；95%CI，3.90-7.47）中，心肺耐力最不健康五分位的肥胖几率最高。这些发现表明，除了心肺健康外，下肢爆发力也与儿童和青少年肥胖有关。
