Question

Describe three rate limiters/controllers for jumping locomotor.

Answer 1

JUMPING
• Jumping is attempted at a young age = before age 2.
• Jumping = individuals propel their bodies from a surface
with either one or both feet and land with both feet.

CHARACTERISTICS OF AN EARLY JUMP

• Changes can be observed in various ways:
The age at which a child can perform certain kinds of
jumps (age norms)
The distance or height of a jump.
The jumping form or pattern.

CHARACTERISTICS OF AN EARLY JUMP
SUMMARY
• Early jumps :
• no crouching and legs are not extended
• not straightened
• No use of two-footed take-off or landing
• Lack of coordinated arm movement, the wing or
parachute

RATE CONTROLLERS IN JUMPING

• To perform a two-footed jump, children
must be able to:

• develop enough force to bring their bodies into the air from a stationary position.

•Jumping likely depends on the postural system’s ability to balance the body on limbs for succession of jumps.

• Enough force must be generated to lift the body with
limbs, recover and quickly generate enough force again to
jump repeatedly.
