Electromyography of speed climbers at start

The speed climbing is ascending 15 m rout in the shortest time, and recognizing of the elite’s muscles involvement in the start could help to improve the start time. Therefore, the purpose of this research is to examine the activity of the muscles involved in the speed start among elite and trained climbers. This is a descriptive-comparative research that has been done by survey and field method. For this purpose, 10 members of the national team were participating in this study, 5 of whom were speed climbers and the others were active in other disciplines of sport climbing. Each of them repeated each start at least 2 times, and the electrical activity of the eight limb muscles was recorded by using the Noraxon electromyography device, which was synced to the Myo-motion device and video camera. There aren’t any significance differences between these two groups. However, the electrical activity in the Gastrocnemius Medialis and Rectus Femoris was higher than other muscles in elite climbers. Trained athlete involved upper limb more in the start movement. If trainer strengthen lower limb muscles in beginners specifically Gastrocnemius and rectusfemoris muscles, we can expect a better star.
