Biomechanical characteristics of waist flexor and extensor muscles in outstanding juvenile male basketball athletes
摘要
Abstract
BACKGROUND:At present, isokinetic testing system has attracted more and more attentions in the evaluation of athlete muscle function, but its application in the detection of waist and abdomen muscle strength characteristics in juvenile male basketbal athletes is rarely reported. OBJECTIVE:To study the biomechanical characteristics of waist flexor and extensor muscles inoutstanding juvenile male basketbal athletes in order to provide the basis for waist and abdominal strength training, scientific selection and prevention of lumbar abdomen injury in basketbal sport. METHODS:Eighteen athletes from the Guangzhou Men’s Basketbal Team were subjected to the detection of muscle strength and work of waist flexor and extensor muscles at 60(°)/s and 180(°)/s using Cybex-Norm isokinetic test system. RESULTS AND CONCLUSION:At the same testing speed, the peak torque and relative peak torque of the extensor muscles were higher than those of the flexor muscles (P<0.01). The increase in the peak torque, relative peak torque and total work of the waist extensor and flexor muscles exhibited a reduced tendency with the increasing of testing speed (P<0.05);the peak torque and relative peak torque of the extensor muscles were decreased more significantly (P<0.01);the relative power of the waist extensor and flexor muscles were increased gradual y with the increasing of testing speed (P<0.01). These parameters were better in perimeter players than in post players. Under the isokinetic concentric contraction, the peak torque ratio of extensor to flexor muscles showed a decreasing trend with the increasing of testing speed and the waist flexor peak torque and extensor muscles flexion showed a decreasing trend, and the trunk stability was weakened. These findings indicate that the muscle strength of the extensor muscles was higher than that of the flexor muscles;the muscles strength of the waist flexor and extensor muscles was better in perimeter players than in post players. In isokinetic rapid movement, the muscle strength of the waist flexor and extensor muscles were reduced and the balance of the muscle strength of the waist flexor and extensor muscles was weakened, suggesting rapid strength training of the waist and abdominal core muscles should be strengthened in juvenile male basketbal athletes.关键词
