In these latter sports, small and supple competitors have an especially good chance to excel, and peak performances tend to come at a relatively young age. Once a competitor matures, it becomes more difficult to acquire or maintain a high level of skill. That is why most competitors in these sports begin training very young.
尤其這些項目適合身材較小、柔軟度較高的選手錶現，巔峰期也出現得比較早，年紀太大就很難練出或是維持好成績，因此這些項目的競技運動員多半提早投入訓練，現今體壇上的頂尖選手，年紀也多半只有十多歲。
