In the Table Tennis, we can generally divide striking form into Fore-hand Stroke and Back-hand Stroke. We can`t decide that which is the important, but in the exorcise and in the practice game, it is true that the interest degree is high in the Fore-hand stroke while the importance of the Back-hand stroke is neglected, though it is always recognized. As it is considered that the analysis can he made by comparing the striking forms of Fore-hand and Back hand, so I put an emphasis on the upper limb which is essential in the striking movement of the Table Tennis, exampling 6 male college players who have had over 6 year earlier, and I take the 6 muscles-Deltodeus, Biceps brachii. Triceps brachii, Flexor Carpiulnaris, Brachier adial is Extensor pollicis longus, as the model objects which were used frequently and main movement muscle groups in the terms of articuli monus, articulus humeri cubiti. articuli manus, articulus humeri, cubiti. As the method of analysis of the muscle movement, Electromyogram surface electrode induction which is necessary to induce as the physiological change and check is taken. So, as the result of the comparative analysis, I can draw several conclusion as follows; 1. Though the difference is exist in each muscle and in earth hand stroke (Fs. Bs), the duration scope of the overall muscle movement time at the table tennis striking form was 0.47∼0.67 sec. and the preparation movement time was 0.15∼0.31 sec. and the remit movement time was 0.22∼0.4 sec. so it is found that the rest movement time is longer than the preparation movement time. 2. The deltoideus in the Fore-hand stroke is long in the duration time and the rest movement time than that of Back-hand stroke, which indicate meaningful difference (p<0.05) 3. Back-hand stroke has the tendency of longer time-span than that of Fore-hand stroke and especially flexor carpiulnaris presents the longer time gap. (p.0.02∼0.05) 4. While Back-hand stroke the other muscles work more long point except extensor pollicis longus and triceps brachii than fore-hand stroke. 5. The muscle movement order is same except deltoideus and flexor carpiulnaris in the Fore-hand stroke and in the muscle shrink order it begins from the deltoideus in the Fore-hand and from the biceps brachii in the Back-hand. 6. Though the difference of the each muscle Amplitude is exist, the times which the ball impact to the racket and represent the maximum of the electromyogram Amplitude are nearly accorded.
