THE INFLUENCE OF COORDINATION BETWEEN UPPER LIMBS\u27 JOINTS ON SPORT LEVEL IN SNOOKER

This study explored the effect of coordination between upper limb joints on the technical level of shooting in billiards.Eight professional and eight amateur players were asked to shoot according to a specific rounte and vector coding method used to quantify the coordination of the motions of the limbs during the shooting stage.For coordination between the flexion and extension of shoulder and flexion and extension of elbow,the proportion of the anti-phase and elbow-phase coordination in the professional group was higher than the amateur group,and the proportion of the shoulder-phase was lower for professional than amateur group. For coordination of the flexion and extension of shoulder and the the adduction and outreach of wrist,the proportion of the wrist-phase coordination in the professional group was higher than the amateur group,and the proportion of the shoulder-phase was lower for the professional than amateur group.These indicators can be used as diagnostic indicators for snooker player\u27s shooting motio

Electro-Acupuncture in Relieving Labor Pain

To study the efficacy of electro-acupuncture for the relief of labor pain, and to build a better understanding of how electro-acupuncture might influence the neuroendocrine system, 36 primiparas were randomly divided into an electro-acupuncture group and a control group. Assessments of pain intensity and degree of relaxation during labor were analyzed. The differences between the electro-acupuncture group and the control group on the concentration of β-endorphin (β-EP) and 5-hydroxytryptamine (5-HT) in the peripheral blood were compared. The electro-acupuncture group was found to exhibit a lower pain intensity and a better degree of relaxation than the control group (p = 0.018; p = 0.031). There existed a significant difference in the concentration of β-EP and 5-HT in the peripheral blood between the two groups at the end of the first stage (p = 0.037; p = 0.030). Electro-acupuncture was found to be an effective alternative or complementary therapy in the relief of pain during labor. The benefit of electro-acupuncture for relieving labor pain may be based on the mechanism of producing a synergism of the central nervous system (CNS) with a direct impact on the uterus through increasing the release of β-EP and 5-HT into the peripheral blood
