The use of large cross-sectional norms on Brazilian children and youths aged 7 to 18 years within a six level competition plan helps to assess development status and monitor change. Non-athletic prototypes for comparative purposes are illustrated by the use of the lowest competitive level of 18 year olds to assess differences from internationally elite players. The purpose of this study was to establish the efficacy of this practice in male and female basketball and volleyball samples. Comparisons were made on 11 anthropometric and performance variables using percent difference (% delta) and z-score values. The z-scores were highest for height, weight, and jumping ability in both sports groups. The volleyball players were the more linear in physique and the better jumpers. Related to their prototypes the female basketball players had the highest estimated VO2 max (ml kg-1 min-1), and the best values of anaerobic power measures. It is concluded that differences in physique and performance at various levels of competition compared to non-athletic prototypes may be used to infer selective and training factors.
在六级竞赛计划中使用巴西7至18岁儿童和青少年的大样本横断面规范，有助于评估发育状况并监测变化。通过使用18岁最低竞技水平的非运动员原型来评估与国际精英运动员的差异，以作比较之用。本研究的目的是确定这种做法在男女篮球和排球样本中的有效性。使用百分比差异（% delta）和z分数值对11个人体测量和表现变量进行了比较。两个运动组的身高、体重和跳跃能力的z分数最高。排球运动员的体型更具线条感，跳跃能力也更好。与她们的原型相比，女篮运动员的估计最大摄氧量（毫升·千克⁻¹·分钟⁻¹）最高，无氧功率测量值也最佳。得出的结论是，与非运动员原型相比，不同竞赛水平下的体型和表现差异可用于推断选择和训练因素。
