Which sports are early specialization sports?

The framework says different activities have different demands and pathways:

• High acrobatic sports such as gymnastics, diving and figure skating are early specialization sports that favour small bodies capable of fast rotation.
• High kinesthetic sports, where developing an early "feel" for the environment or equipment is important, such as swimming, soccer and racquet sports.
• Common (standard) sports have the typical timing of specialization, with peak performance in the late 20s or early 30s.
• Late specialization sports, where peak performance can occur in the mid-30s or later, such as golf, rowing or triathlon.
• Transfer sports are ones people do not generally take part in before late adolescence, such as bobsleigh.

Except in early specialization sports (gymnastics, figure skating and diving), the framework says athletes should not over-specialize until their early teens.
