Abstract

Acupuncture as a traditional and commonly used treatment has been used to improve the performance of athletes. In the improvement of female shoulder joint explosive force and muscle endurance also has an immediate effect. However, whether the effect of acupuncture therapy can be maintained after improving athletic performance still worth further discussion. The purpose of this study was to explore the timeless of the physical neurophysiological response induced by acupuncture at specific acupoints in improving endurance performance. Seventeen healthy male participants completed six groups of shoulder joint isokinetic exercises. The isokinetic exercise completed in the first group was taken as the baseline. After acupuncture for 15 min, the following 5 isokinetic experiments were completed. Acupuncture acupoints included Binao (LI14), Jianliao (SJ14), Naohui (SJ13), Zhongfu (LU1), Xiabai (LU4), Tianfu (LU3) and Xiaoluo (SJ12). The results show that acupuncture can improve physical performance for 10–20 min. After acupuncture, the maximum torque, average power, average work and total work values significantly increased (p < 0.05). Stimulation of acupoints can effectively improve the performance of periarticular muscle endurance around the shoulder, but this improvement is limited by time.

Highlights

Acupuncture, the most familiar complementary and alternative therapy to Western medicine, has a history of more than 3000 years in China and is still used to treat diseases and relieve pain [1]
The maximum torque of extensor (Figure 5B), the average power of flexor (Figure 5C), the average work of flexor (Figure 5E) and the total work of the flexor muscle (Figure 5G) were significantly different at Post 1, Post 2 and Post 3 (ES varying from 0.9 to 2.05, all p < 0.05), indicating that the time of acupuncture improving the muscle strength of the muscle group could last for 23 min
The current study suggests that the use of acupuncture as replacement therapy could generate the benefits of PAP or “De Qi” to improve shoulder joint endurance

Summary

Introduction

Acupuncture, the most familiar complementary and alternative therapy to Western medicine, has a history of more than 3000 years in China and is still used to treat diseases and relieve pain [1]. Acupuncture is important in treating diseases, relieving pain and restoring health. Past studies found that acupuncture at specific acupoints can induce parasympathetic excitation of the body and produce “De Qi” [4,5,6,7], “De Qi” is thought to be caused by myosin regulating light chain phosphorylation in connective tissue fibroblasts that alters the increased sensitivity of actin and myosin Ca2+ to enhance strengthening of the muscles [8]. Acupuncture stimulation of the muscle surface can induce changes in potential in the body to the central nervous system to accelerate limb movements [10] and stimulating neurons in the deeper or shallower layers of the skin causes muscles to contract in a way that strengthens the body and helps
