Abstract: The aims of the present study were to compare the elite tennis player(ETP) and amateur tennis player(ATP): (1) the difference on muscle electromyography(EMG) while striking, (2) the difference on racket, wrist and elbow vibration while striking, (3) the relationship among all the parameters. The results of study showed that: on the follow-through phase(FTP) of forehand(FH) with or without brace, the reaction of EMG of wrist extensor muscle(WEM) on ATP is higher than ETP. On backhand(BH) with or without brace, the vibration of prepare phase(PP)and FTP on racket, wrist and elbow is higher in ATP. The vibration of racket on BH is higher than FH on PP and FTP with or without brace on ETP. The vibration of wrist and elbow on FH is higher than BH on PP and FTP with or without brace on ATP. Most of the parameters are correlated for the ETP including the muscle range(MR) and grip force(GF), training yesrs(TY) and age, EMG of forehand flexor muscle(FFM) without brace on PP and wrist vibration, EMG of backhand flexor muscle(BFM) without brace on PP and (EMG) of forehand flexor muscle (FFM)without brace on (PP), EMG of BFM without brace on FTP and EMG of FFM without brace on FTP. And for ATP, the MR and GF, TY and age, wrist vibration and GF, elbow vibration and wrist racket vibration are correlated. Both of the ETP wrist flexor and extensor muscle appeared co-contraction on FH and BH PP, but the ATP didn''t. From the results of the study, we could know that wearing tennis brace and increase forearm muscle strength can reduce vibration, and the co-contraction of muscle can prevent the occurrence of tennis elbow.
