The calf raise test (CRT) assesses plantarflexor strength and endurance, but normative data for children are scarce. Furthermore, contradictions exist on which factors are associated with total repetitions, with repetitions being the only metric considered. We quantified three of the main CRT outcomes (repetitions, total work, and peak height) in children 10-17 years and explored their relationship with various factors.
Healthy children ( = 165, 50.3% female) completed single-legged calf raises on a 10° incline, once on each leg. Test outcomes were extracted using the valid and reliable Calf Raise application.
CRT outcomes were not significantly different between legs ( ≥ .19). The only covariates significantly associated with outcomes based on stepwise quantile regressions were body mass index centile for repetitions, meeting physical activity recommendations for total work and peak height, and age for total work. Outcomes did not significantly differ based on sex or maturation. Median values were around 26 for repetitions, 640-1460 J for total work (age dependent), and 10.1 cm for peak height for children meeting physical activity recommendations.
Children who were older, had lower body mass indices, and were more active exhibited superior CRT outcomes. Meeting physical activity recommendations appears beneficial for plantarflexor function and should continue to be prioritized in children.
提踵试验（CRT）用于评估跖屈肌力量和耐力，但儿童的规范数据稀缺。此外，关于哪些因素与总重复次数相关存在矛盾，而重复次数是唯一被考虑的指标。我们对10至17岁儿童的三项主要CRT结果（重复次数、总功和峰值高度）进行了量化，并探讨了它们与各种因素的关系。
健康儿童（n = 165，50.3%为女性）在10°斜坡上进行单腿提踵，每条腿各做一次。使用有效且可靠的提踵应用程序提取测试结果。
两腿之间的CRT结果无显著差异（P≥0.19）。基于逐步分位数回归，与结果显著相关的唯一协变量是重复次数的体重指数百分位数、达到身体活动建议量与总功和峰值高度相关，以及年龄与总功相关。结果在性别或成熟度方面无显著差异。对于达到身体活动建议量的儿童，重复次数的中位数约为26次，总功为640 - 1460焦耳（取决于年龄），峰值高度为10.1厘米。
年龄较大、体重指数较低且更活跃的儿童表现出更好的CRT结果。达到身体活动建议量似乎对跖屈肌功能有益，在儿童中应继续将其作为优先事项。
