Background: Three commonly used non-invasive protocols are implemented to estimate the timing at which PHV most likely occurs. Accurate estimation of circumpubertal years can aid in managing training load of adolescent athletes.

Aim: Three protocols were compared against observed age at PHV: an estimate of 13.8 ± 1.0 years - generic age at PHV (from longitudinal measures); an estimate based on the maturity offset equation, predicted age at PHV ±1.0 year; a window of PHV based on 85 – 96% of predicted adult height at time of observation.

Subjects and methods: A final sample of 23 (from 28) adolescent participants who were selected from the academy of an English Premier League club. Anthropometric measures were collected across five playing seasons; age at PHV was estimated with Super-Imposition by Translation and Rotation (SITAR). The three protocols were compared based on measures at 13.0 years.

Results and Conclusions: An age window based on predicted maturity offset did not improve estimation of PHV compared to generic age method; however, the percentage of predicted adult height window showed improvement in performance shown by the following results. Predicted age at PHV correctly assigned 15 participants (65%) as experiencing PHV, while the percentage height correctly assigned 17 participants (74%). Generic age and predicted age at PHV correctly predicted observed age at PHV for 14 participants (61%), percentage of adult height window correctly predicted 22 participants (96%).

背景：实施了三种常用的非侵入性协议以估计最有可能发生PHV的时间。准确估计青春期的年龄可以帮助管理青春期运动员的训练负担。

目的：将三种方案与观察到的PHV年龄进行比较：估计为13.8±1.0岁-PHV的一般年龄（根据纵向测量）；基于成熟度补偿方程式的估计值，PHV±1.0年的预测年龄；PHV的窗口基于观察时成人预计身高的85 – 96％。

对象和方法：从英超联赛俱乐部的学院中选出的23名青少年参与者（来自28名）的最终样本。在五个比赛季节中收集了人体测量学数据；通过平移和旋转叠加（SITAR）估计了PHV的年龄。根据13.0年时的测量结果比较了这三个协议。

结果与结论：与通用年龄方法相比，基于预测的成熟度偏移的年龄窗口并不能改善对PHV的估计。但是，预测的成年人身高窗口百分比显示出以下结果所示的性能改善。在PHV的预测年龄正确分配了15名参与者（65％）为经历PHV，而在身高百分比中正确分配了17名参与者（74％）。普通年龄和PHV的预测年龄正确地预测了14位参与者在PHV的观察年龄（61％），成人身高窗的百分比正确地预测了22位参与者（96％）。
