20 terms

The coordination abilities under every tennis skill.

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

How well the brain organizes movement using information from the senses. General abilities are learning, controlling and adapting movement. Special abilities include reaction, balance, combining movements, orientation, rhythm, fine control, anticipation and movement creativity.

Say it on court

“Coordination is trainable, and ages 6–11 are the best window for it.”

Reaction
CoachesPlayers
Red (Ages 5–8)

Say it on court

“Go on the bounce, not on my voice.”

Balance
