Isokinetic strength of the trunk and lower limbs in basketball players
摘要
Abstract
BACKGROUND: There is a lack of comparative data concerning isokinetic muscle strength of elite female basketball players with different athletic levels. OBJECTIVE: To investigate the characteristics of muscle strength of trunk and lower limbs of elite female basketball players, and to compare the difference in the muscle strength between elite athletes and first-class athletes. METHODS: Sixteen Sichuan Provincial (first-class group), and 17 members of the national team (elite group) female basketball athletes were enrolled, and the flexion and extension muscle strength of trunk, hip, knee and ankle joints in different angular velocity (60(°)/s, 5 times;240(°)/s, 25 times) were detected using the German IsoMed 2000 isokinetic testing. RESULTS AND CONCLUSION: The right hip extensor and flexor force absolute power, bilateral knee flexor and extensor force and absolute flexion explosive, bilateral ankle flexor and extensor and the explosive force in the elite group were significantly higher than those in the first-class group (P < 0.05).The trunk flexor strength, left hip extensor force and absolute outbreak right hip extensor force and explosive force in the elite group were significantly higher than those in the first-class group (P < 0.01). In the elite group, the hip knee ankle muscle: the absolute strength of flexor 5.0:3.6:1, flexor extensor 5.0:3.2:1 explosive force, absolute force 2.4:1.6:1, extensor explosive force 2.0:1.3:1; in the first-class group had 6.3:3.8:1 absolute strength of flexor flexor, explosive force 6.6:4.2:1, 2.3:1.8:1 absolute extensor force, and 1.8:1.5:1extensor explosive. There were significant differences in the antagonistic/active muscle ratios of torso explosive force, absolute strength of bilateral hip and knee joint and explosive force between two groups (P < 0.05). The lower extremity joint contralateral homonymous muscle in both groups was less than 10%. The trunk flexor and extensor, bilateral hip extensor and bilateral ankle extensor endurance in the elite group were significantly higher than those in the first-class group (P < 0.05). These findings suggest that with the increase of test angle, both groups showed a decrease in trunk and lower limb flexor extensor peak torque to different extents. The lower limb contralateral homonymous muscle was < 10% in both groups. Additionally, the first-class athletes should strengthen the trunk flexor strength, hip flexor and extensor force and absolute power, absolute knee extensor force and ankle flexion, absolute strength and explosive force exercises, also need to increase trunk flexor and extensor, hip and ankle extensor endurance training.关键词
