Abstract
A total of 53 subjects were recruited (18 men and 35 women) belonging to the Pura Vida Athletics Cheerleading program (Tibás, Costa Rica). Three groups were randomly formed: Trampoline Group (GT), Control Group (GC), and Normal Training Group (GEN). GT followed a traditional ET treatment (approximate duration 45 min; intensity 75-85% of maximum heart rate). Pre-test and post-test measurements of stability (pressure center), speed in 20-m sprints, and jump height (CMJ) were conducted. Regarding stability, GT significantly worsened (p<0.05*) in a bipedal stance compared to GC and, in Liberty, Awesome, and Arabesque stunts GT worsened significantly (p<0.05*) compared to GC and GEN. Height of CMJ of GT was significantly lower (p<0.05*) with respect to GEN, but not with respect to GC. Speed in 20-m sprints of GT decreased significantly (p<0.05*), while GC (p>0.05) and GEN (p>0.05) did not have a significant change. In conclusion, there was a significant decrease in stability of GT in a bipedal stance and in Liberty, Awesome and Arabesque stunts. Height of CMJ of GT had a non-significant decrease, while speed in 20-m sprints of GT was significantly lower after ET.
