青少年Wingate无氧功率与下肢骨骼、肌肉形态的关系

研究目的:探讨30秒Wingate无氧功率测试指标与骨骼、肌肉的形态的关系。研究对象与方法:29名19-21岁青少年参加测试,超声法测量小腿三头肌及其肌腱,常规方法测量其它形态学指标,Wingate法测量下肢无氧功率,运动5min后测取血乳酸值。结果:最高功率、最高功率/公斤体重、平均功率、平均功率/公斤体重男性均高于女性,WAT运动后5分血乳酸值男性显著高。结果表明:男性组瘦体重与平均功率显著正相关,女性组大、小腿围度与平均功率显著正相关,下肢肌肉骨骼的形态学指标与下肢无氧功率在两组间均无明显相关。

Relation of Youngsters'''' Wingate Anaerobic Power to Lower Extremity Bones and Muscular Shape

Purpose: To find out the relation of the indices of 30s Wingate anaerobic power to bonesand muscular shape. Methods: 29 youngsters of 19-21 years old were tested. Ultrasonic wave wasapplied to test the tricps of the shank and the tendon. The other indices of morphology were obtained bynormal methods. The way of Wingate was used to measure the anaerobic power of lower extremity. Andblood lactic acid was tested 5min after the exercise. Result: top power, top power/kg. weight, averagepower and average power/ kg.weight of the male are higher than those of the female. 5min after WATexercise, the blood lactic acid of the male is obviously high. Conclusion: Thin weight of the male grouphas a positive relation to average power. The thigh and shank measurements of the female group havea positive relation to average power. The morphological indices of the lower extremity muscle and boneof both groups have no obvious relation to lower extremity anaerobic power.
