- Abstract
- The purpose of this study was to analyze the muscle activities in golf approach of professional & amateur golfers, and provide the guideline of training in golf approach. Using electromyography (EMG), we evaluated muscle activities in 11 professional & 11 amateur golfers during golf approach swing. Surface electrodes were used to record the level
of muscle activities in the Extensor carpi radialis longus (ECRL), Brachioradialis (BR), Palmaris longus (PL) muscles during the swing. These signals were compared with %RVC(Reference voluntary contraction) which was normalized by IEMG (Integrated EMG). The approach swing were divided into three phases: Back swing, Down swing, Follow through
phase. The results can be summarized as follows; there were significant increase of left PL muscle in pro golfers during back swing of 15m approach shot (p<0.05). There were significant decrease of right ECRL muscle in pro golfers during down swing of 50m approach shot (p<0.05). There were significant decrease of left PL and right BR muscles in pro golfers
during follow through of 30 m shot, while significant increase of left BR muscle during follow through of 50 m shot (p<0.05). The results showed that the approach swing should require a controlled force in forearm and smoothing swing.
