Tumbling (gymnastics)

In gymnastics, tumbling, also known as power tumbling, is an acrobatic sporting discipline which combines some of the skills of artistic gymnastics on the floor with those of trampolining. It is practised on a 25-metre long spring track. It was developed from tumbling performances performed by entertainers from very early times but as a sport is now codified, regulated, judged, and performed using standardised special acrobatic equipment.
