There is an increasing consensus on the relevance of musculoskeletal fitness for health throughout the life cycle, requiring evaluation approaches and description of results capable of characterizing different age groups and body sizes. This study aimed to describe the musculoskeletal fitness of young Portuguese people aged 10-18 through handgrip strength (HGS) and vertical jump power (VJP) and investigate differences between the sexes.
The sample included 736 participants (359 girls recruited from schools. HGS (kg) was assessed using a handheld dynamometer, and VJP (W) was assessed using a force platform; both measurements were standardized for body mass.
Higher HGS and VJP were observed in boys than in girls from 13 years old (13 years: ≤ 0.05; 14-18 years: ≤ 0.001), with no significant differences before this age. The percentile distributions of HGS and VJP are described for each sex using the lambda, mu, sigma (LMS) method. The pattern of development of these variables as a function of age is presented.
Handgrip strength and vertical jump power show differences between the sexes from 13 years of age and similar trajectories to populations in other countries in the same age group.
关于肌肉骨骼健康在整个生命周期对健康的相关性已达成越来越多的共识，这需要能够表征不同年龄组和体型的评估方法及结果描述。本研究旨在通过握力（HGS）和垂直跳功率（VJP）描述10至18岁葡萄牙年轻人的肌肉骨骼健康状况，并调查性别差异。
样本包括736名参与者（359名从学校招募的女孩）。使用手持式测力计评估握力（千克），使用测力平台评估垂直跳功率（瓦）；两种测量均按体重进行标准化。
13岁起男孩的握力和垂直跳功率高于女孩（13岁：≤0.05；14至18岁：≤0.001），在此年龄之前无显著差异。使用λ、μ、σ（LMS）方法描述了每种性别的握力和垂直跳功率的百分位数分布。呈现了这些变量随年龄变化的发展模式。
握力和垂直跳功率从13岁起显示出性别差异，并且与其他国家同年龄组人群的轨迹相似。
