Document Summary

Strength and balance are the rate limiters for early walking: arms are in high guard, limited rom, short stride length, little rotation. Increased rom and use of the knees and hips. Jump: individual propels self off ground with one or two feet, lands on two feet: hop: most difficult due to balance and coordination. Individual propels self off ground with one foot, lands on same foot. Leap: individual propels self off ground with one foot, extends flight period, lands on opposite foot. Jumping: children often begin simple jumping before age 2. Individuals can perform either vertical or horizontal (standing long) jump: generic difference in height may influence the technique, early jumpers have a hard time coordinating limbs for jumping. Early characteristics of jumping include: one-foot takeoff or landing, only jumping vertically, no or limited prepatory movements. Proficient jumping: prepatory crouch maximizes takeoff force. For vertical jump, force is directed downward; body is extended.
