High Jump Athletes Swing Leg Joint Flexion Muscles Concentric Heart Test

The high jump is strength, speed, flexibility, sensitive physique as a whole,through the rhythm of the run-up, takeoff, vacated over the bar, floor sports. Goodresults once our male and female high jumper in the world game won manydistinctions, especially male athletes Zhu Jianhua broke the world record three timesin a row and won the men’s high jump bronze medal in the1984Los AngelesOlympic Games. However, with the development of the times, the foreign high jumpathletes leaps and bounds, and China’s high jump athletes has worsened, and can notcontribute much. March7,2013, the National Indoor Championships in Nanjingstation’s high jump final, Shandong teenager Zhang Guowei jumped out of the2m32best results, refresh Zhu Jianhua in1986to create and maintain a27-year-old31meters national record, but there is still a small gap and of Zhu Jianhua outdoor in1984to create the2m39bests. The scientific training means and methods we needcontinuous efforts specializes, high jumpers muscle assessment imminent.Fosbury Flop, lower extremity strength played a decisive role in athleticperformance, which is particularly important swing leg. Swing leg action technologyis divided into the support phase, take-off the flight phase, put to the mostsubstantial braking stage, its good or bad for technology mastered one of theimportant indicators to take excellent skills. Therefore, this paper Cybex isokineticsystem, flexion and extension muscles of the the swinging leg joint32ExcellentJumpers isokinetic testing ankle to30O/s,60O/s,90O/s to test, hip60O/s,90O/s,150O/stest knee to60O/s,90O/s,120O/s-test, combined with the movement of acomprehensive evaluation of the anatomy of the the swinging leg joints muscle forthe coaches to provide scientific, effectively, a systematic training methods, topromote the development of China’s High Jump.Study track and field team from Liaoning Province and Dalian City Sports School32high jumpers. Female group A woman level athletes8and8and femalegroup B of the women’s two athletes, the man was an athlete8ie male group A, twomen athletes8and M B group.Result:(1) ankle:30O/s to90O/s is incremented, four groups of male and femaleathletes ankle flexion muscles peak torque decreasing, are greater than the flexor andextensor. Speed of30O/s and60O/s, the flexor peak torque and total work of thewomen’s group A were higher than women’s group B; woman flexor peak torque andthe total of the two groups when the speed of90O/s quite reactive, no significantdifferences in relative peak torque of the woman in the two groups in each speedflexor; the woman group A extensor relative peak torque at every speed is greaterthan the women in group B, but the woman groups extensor peak torque and the totalwork is not a significant difference, the the woman two groups flexion than nodifference. A group of men in each speed peak torque relative peak torque, flexionand extension ratio and total power, are larger than the men’s group B.(2) Knee:30O/s to90O/s increments peak torque, four groups of male andfemale athletes knee flexion muscles are constantly decreases are greater than theflexor and extensor. Women’s Group A of flexion and extension muscle peak torqueat each speed, the relative peak torque, total work and flexion and extension thanwere higher than women’s group B. A group of men flexor peak torque and totalwork than men in three speed, group B, no significant difference between two groupsflexor relative peak torque, man extensor peak torque relative peak torque, totalwork quite; men flexion and extension than there is no significant difference in thetwo groups.(3) hip:60O/s to150O/s is incremented, four groups of male and female athletesof hip flexion and extension muscles peak torque decreasing, are greater than theflexor and extensor. Women’s Group A of flexion and extension muscle peak torqueat each speed, the relative peak torque, total work and flexion and extension thanwere higher than women’s group B. Similarly, the men’s group A at each speed of theflexor and extensor peak torque relative peak torque, total work and flexion than arelarger than the men’s group B. Conclusion:(1) in the swing of the leg muscles and ankle flexion and extension analysisshowed that: the woman a high jump athletes ankle flexor strength, endurancewoman were greater than two, the relative strength of two woman quite; woman anextensormaximum strength and endurance with the woman in two quite woman onlyin the relative strength of greater than two. And the two groups did not differsignificantly in the flexion and extension balance ability, indicating that the womanwas a high jump athletes ankle flexion muscles training efficiency problems. Man ahigh jump athletes ankle flexion and extension muscles strength, relative strength,balance the flexion and extension capabilities and endurance are greater than theman two.(2) woman a high jump athlete swing leg knee flexion and extension musclestrength, relative strength, endurance and flexion ratio is greater than the woman two.Man an athlete than men only in the maximum strength and endurance of the flexortwo, the rest of the muscle strength data are two with the man fairly. The descriptionof the man was a high jumpers knee flexion and extension muscles training effect isnot ideal swing leg knee flexion and extension muscle strength training to improvehow the system is needed to solve the problem.(3) a high jumpers flexion muscles maximum strength, relative strength,flexion and extension, balance and endurance are more than two high jumpers. Thisis only one athlete tested in three joint muscle strength data are better than twoathletes of the joint, thereby positively related to contact with the high jump resultsswing leg hip flexion and extension muscle strength high jump results importantrole.(4) female athletes as compared to men athletes in the overall relativestrength and range of motion balance, the overall effect of the training of femaleathletes as compared to men athletes.
