| As fullswing action is the most basic action in golf sport, its research plays a larger proportion in the golf research, the movement will provide the theoretic basis and guidance for golf if its action is scientific and reasonable for training and teaching.This study adopts EMG and kinematics method combining with Driver, club 4-iron, club 7-iron and Pitching wedge for representing club. nine high level vocational coaches'motion is analyzed in Beijing GaoRun golf club, according to the muscles iEMG trend, different fullswing work characteristic'difference, muscle discharge sequence, muscle mainly forcibly work characteristic, Shot instantly RMS and maximum RMS peak, fullswing iEMG values etc.Results:(1) Muscle work features is significantly different in Driver and 7-iron, Muscle work features on 4-iron and 7-iron is most close. (2) The action of fullswing, PM-R LD-R TB-L TMOB-L RA-L ES-R ES-L OEA-L OEA-R MG-R RF-L BF-L BF-R are the major surface muscle on swing stage; Golfer should strengthen the muscle strength training above. (3) The first discharge muscle is TB-L in fullswing Temporal characteristics, next OEA-L OEA-R MG-R; TMOB-L is last in Follow-through. (4) The time swing Driverl is longer than 7-iron. (5) The TB-L main work longest, followed by the OEA-L muscle. The RA-L MG-L BF-Lf on Driver and 7-iron fullswing main force in a relatively short time. the percentage of time in all participants'muscles mainly work are not consistent, the biggest difference of TB-L MGAS-L muscle, the smallest of MG-L BF-L. (6) Every muscle maximum RMS spikes in the process of the time difference between individuals in fullswing, all the brandish lever instantly all muscle did not reach their peak RMS. (7) In fullswing, swing Driver the muscle put power is biggest than P-stem, the TB-L contribute to the swinging movements is maximum and GM-L minimum. Conclusion:(1) Muscle work features is significantly close in 4-iron,7-iron and P-rod;but most different in Driver. Tip:Driver and iron-rod should be exercise differently in fullswing, note the types rod cause forcibly differences, technology moves develop balanced.(2) The results indicated that fullswing in the golf should be paid attention to in practice and teaching in accordance with the power of each link timing rule chain. Namely with arms on pole stage with shoulder to shoulder with hip, downswing phase is lower limb, torso, Upper limbs driven the timing features, to improve the purpose of action techniques of fullswing.(3) Fullswing showed muscle forcibly biggest point-in-time later in the characteristics of ball moment, tip:Golf practitioners should be paid attention to accelerate under continuous force to pole stage in fullswing, and after the hit standard movement should be complete in followswing, to form the correct muscles feeling and dynamic stereotypes. |
