摘　　要：目的:旨在探索亚洲举重锦标赛59公斤级别女子举重冠军龙雪腰背肌和下肢三关节肌力特征,找出薄弱肌群,为龙雪及其他女子举重运动员科学化力量训练提供参考。方法:采用德国ISOMED 2000等速肌力测试系统对龙雪腰背、髋、膝、踝关节进行不同角速度的等速向心峰力矩测试。结果:龙雪腰背部屈伸肌比值为42.9%—53.3%;左髋屈伸肌比值为26.5%—31.3%、右髋屈伸肌比值为28.9%—32.5%、髋关节异侧同名屈肌比值为4.6%—14.3%、异侧同名伸肌比值为0.4%—5.7%;左膝屈伸肌比值为66.4%—70.4%;右膝屈伸肌比值为48.7%—63.6%,膝关节异侧同名屈肌比值为3.5%—6.4%、异侧同名伸肌比值为12.9%—24.7%;左踝屈伸肌比值为25.4%—28.8%,右踝屈伸肌比值为41.7%—54.5%,踝关节异侧同名屈肌比值为24.0%—40.0%,异侧同名伸肌比值为10.4%—35.3%。结论:亚锦赛冠军龙雪腰背部屈肌力量薄弱;两侧髋关节屈肌力量薄弱、髋关节异侧同名伸肌比值正常,异侧同名屈肌处于易损伤范围;两侧膝关节屈伸肌比值健康,异侧同名屈肌合理范围中,异侧同名伸肌处于易损伤范围;左踝关节屈伸肌比值较低,右踝屈伸肌比值正常,两侧同名屈、伸肌比值均处在易损伤范围,尤其以踝关节同名屈肌严重。OBJECTIVE:The study explored the muscle strength characteristics of dorsal muscle and three joints of lower limbs of Long Xue,female weightlifting champion of 59 kg category at Bahrain 2022 Asian Weightlifting Championships,and found out the weak muscle groups to provide reference for scientific strength training of Long and other female weightlifters.METHOD:The ISOMED 2000 isokinetic dynamometer was used to test the isokinetic concentric peak torque of Long's dorsal,hip,knee and ankle joints at different angular velocities.RESULTS:Long Xue's dorsal flexor/extensor ratio was 42.9%-53.3%,the left hip flexor/extensor ratio of 26.5%-31.3%,the right hip flexor/extensor ratio of 28.9%-32.5%,the left-right hip flexor ratio of 4.6%-14.3%,and the left-right hip extensors ratio of 0.4%-5.7%;left knee flexor/extensor ratio of 66.4%-70.4%,right knee flexor/extensor ratio of 48.7%-63.6%,the left-right knee flexors ratio 3.5%-6.4%and extensors ratio of 12.9%-24.7%,respectively;the left ankle flexor/extensor ratio of 25.4%-28.8%,the right ankle flexor/extensor ratio of 41.7%-54.5%.The left-right ankle flexors ratio of 24.0%-40.0%and extensors ratio of 10.4%-35.3%.CONCLUSIONS:Weightlifter Long Xue has weak strength in lumbar and back flexors.The flexors at both sides of the hip joint was weak;the hip joint left-right extensors ratio was normal,but flexors of the hip joint were in the range of high injury risk.The knee flexor/extensor ratios on both sides were healthy,the left-right flexors ratio in a reasonable range,and the left-right extensors ratio in the range of high injury risk.The left ankle flexor/extensor ratio was low,whereas the right ankle flexor/extensor ratio was normal,and the left-right flexors ratio and the left-right extensors ratio were both in the range of high injury risk,especially the flexors of the ankle.
