Study of EMG differences in coordinate movement of waist and abdomen muscles

Abstract

Use Finland MuscleTesterME6,000 portable eight-guided surface EMG to record the waist and abdominal muscle electrical signal when eight shot put athletes are throwing shot puts of different quality (6, 7.26, 8 kg). The analysis results show that: when the waist and abdomen muscle mobilization order in the throwing game with the ball of 7.26 kg, the athletics are at their most theoretical status. In addition to this, the muscle discharge duration is shorter, and there are smaller IEMG values. The overall coordination capacity of the muscle is better than throwing shot puts of 6 and 8 kg. When throwing the lighter shot put (6 kg), the waist muscle IEMG value is higher with greater force. There are some meanings to the waist strength training. When throwing a heavier quality shot (8 kg), waist muscle force order is consistent to the 7.26 kg group, which has some supporting role to the study of the standard technical actions. © 2013 Springer-Verlag.
