A high level of physical fitness in childhood and adolescence is associated with more favorable phy sical and mental health outcomes.
To compare body adiposity and horizontal jump per formance with international studies and to analyze the relationship between body adiposity and ho rizontal jump performance indicators in children and adolescents.
Descriptive study conducted on 812 adolescents from Talca (Chile), with an age range between 10.0 and 16.9 years. Weight, height, waist circumference (WC) and Horizontal jump (HJ) were evaluated after warm-up for 10 to 15 minutes to evaluate the explosive strength of the lower extremities according to the protocol of Castro-Piñero et al. Adiposity and HJ were compared with national and international studies. The data normality was verified by the Kolmogorov-Smirnov test. Smoothed percentile cur ves (p50) were created for BMI, WC, and HJ for each gender according to the LMS method.
Adolescents showed differences in body adiposity and HJ performance with international studies. In both genders, negative and significant correlations were found between the BMI and the HJ (men r = -0.104 and women r = -0.149) and between the WC and the HJ (men r = -0.100 and women r = -0.131). The adolescents who were classified in tertile 1 (good) and tertile 2 (satisfactory) had lower body adiposity (BMI and WC) and better HJ performance than those in tertile 3 (poor).
Higher body adiposity and lower HJ performance were observed compared to international studies. In addition, a negative relationship between body adiposity and HJ was found. These findings suggest that the progressive increase of adiposity as age increases negatively affects the strength performance of the lower extremities of the studied children and adolescents.
儿童和青少年时期的高水平身体素质与更有利的身心健康结果相关。
将身体肥胖程度和立定跳远成绩与国际研究进行比较，并分析儿童和青少年身体肥胖程度与立定跳远成绩指标之间的关系。
对来自智利塔尔卡的812名青少年进行描述性研究，年龄范围在10.0至16.9岁之间。按照卡斯特罗 - 皮涅罗等人的方案，在进行10至15分钟热身运动后，评估体重、身高、腰围（WC）和立定跳远（HJ），以评估下肢的爆发力。将肥胖程度和立定跳远成绩与国内和国际研究进行比较。通过柯尔莫哥洛夫 - 斯米尔诺夫检验验证数据正态性。根据LMS方法为每个性别创建BMI、WC和HJ的平滑百分位数曲线（p50）。
青少年在身体肥胖程度和立定跳远成绩方面与国际研究存在差异。在两个性别中，BMI与立定跳远之间均发现负相关且具有显著性（男性r = -0.104，女性r = -0.149），WC与立定跳远之间也存在负相关且具有显著性（男性r = -0.100，女性r = -0.131）。被归类为第一三分位数（良好）和第二三分位数（满意）的青少年比第三三分位数（差）的青少年身体肥胖程度更低（BMI和WC），立定跳远成绩更好。
与国际研究相比，观察到更高的身体肥胖程度和更低的立定跳远成绩。此外，发现身体肥胖程度与立定跳远之间存在负相关。这些发现表明，随着年龄增长肥胖程度的逐渐增加会对所研究的儿童和青少年的下肢力量表现产生负面影响。
