Alternating versus blocked practice in learning a cartwheel.

This investigation examined the generalizability of contextual interference to learning the cartwheel in gymnastics. 32 participants ages 17 to 26 years completed five stages of practice of two versions of the skill, one in which the left hand led and one in which the right hand led, providing a total of 192 practice trials. Practice of these two versions of the task was completed in either a blocked or alternating order.
