本研究探讨了初中儿童的跑步速度和纵跳的增长率。45名11-13岁的男孩和31名女孩在学年期间进行了三次（9月，2月和5月）跑步速度和垂直跳跃测试。分层线性模型用于估计整个样本的初始状态和生长速率（基础模型）以及跑步和垂直跳跃与身高、体重和性别的相关性（条件模型）。跑步速度和垂直跳跃的总体增长率均为正。在测量时，身高和体重的增加与跑步的增长率没有显着相关性。纵跳的增长率与身高呈正相关，但与体重的增加无关。在跳跃方面，男孩比女孩表现出更快的增长速度。无论是初始状态还是生长速度，都没有发现性别差异。此外，这些结果表明，身体成熟的高度可变的速度，但没有一般时期的“青少年尴尬”。
This study examined growth rates in running speed and vertical jump among middle school children. 45 boys and 31 girls ages 11–13 years were tested on running speed and vertical jump three times (September, February, and May) during the school year. Hierarchical linear modeling was used to estimate initial status and growth rates for the entire sample (base model) and the association of running and vertical jump with height, weight, and sex (conditional model). Positive overall growth rates were found for both running speed and vertical jump. Increased height and weight at the time of measurement were not significantly associated with growth rate for running. The growth rate for vertical jump was positively associated with height but unrelated to increased weight. Boys showed steeper growth rates than girls in jumping. No sex differences were found in running speed for either initial status or growth rate. Furthermore, these results suggest highly variable rates of physical maturation but no general period of ‘adolescent awkwardness’.
