TMG-Based Study on Muscle Status Characteristics of Throwing Athletes
OBJECTIVE:This study aims to quantitatively analyze the muscle status of throwing athletes using non-invasive muscle diagnostic technology called Tensiomyography(TMG).It explores the muscle status characteristics of throwing athletes and provides recommendations for their training practices.METHOD:The study utilizes literature review,experimental methods,and mathematical statistics.RESULTS:Significant differences(P＜0.05)were found in the Tr indicators of the left and right vertical spinal muscles and pectoralis major muscles of throwing athletes.The similarity of upper limb muscles and trunk muscles was higher than that of lower limb muscles,and the similarity of back muscles on the left and right sides of the trunk was higher than that of abdominal muscles.The similarity of measured muscles from high to low on the left and right sides were as follows:middle part of the trapezius muscle(76%),rectus abdominis muscle(73%),finger flexor muscle(73%),brachialis muscle(72%),biceps brachii muscle(72%),upper part of the trapezius muscle(71%),latissimus dorsi muscle(70%),lower part of the trapezius muscle(70%),tensor fasciae latae muscle(70%),rectus femoris muscle(67%),peroneus longus muscle(63%),anterior deltoid muscle(63%),adductor magnus muscle(62%),peroneus brevis muscle(58%),external oblique muscle(58%),vertical spinal muscle(56%),soleus muscle(56%),tibialis anterior muscle(55%),pectoralis major muscle(55%),biceps femoris muscle(41%).The similarity of muscles in each group was at a relatively low level of 63.5%±9.01%.CONCLUSION:Throwing athletes exhibit muscle asymmetry,with high fatigue and increased risk of injury in muscles such as the rectus abdominis,latissimus dorsi,trapezius,adductor magnus,and biceps brachii.SUGGESTIONS:Coaches should intervene purposefully to address the asymmetry between the left and right limbs of throwing athletes.This includes reducing the exercise intensity and training load of fatigued muscles,incorporating relaxation techniques and allowing sufficient rest time to minimize the risk of injury and prolong the athletic career.
