The Quantitative Research On The Abilitities Of Cooperation Of Male College Students

Purposes of research: The human motion is complex，but the scientists of differentresearch fields have also recognized the importance of sport coordination in the humanmotion. It was found from the relative documentation that many scholars had studied theinfluencing factors， developing periods， measuring methods and training of thechildren’s coordination and so on， but it is so little and almost empty in our country tostudy， test and estimate the adult college students. This paper， according to testing thestanding long jump for the male college students of PE major and non-PE major，quantitatively analyses the coordination to provide the more abundant means and methodsfor the evaluation of coordination， and the theoretical basis and timing methods for theresearch of coordination.Methods of experiment: According to the research， the normal developed malecollege students from South of Jiangsu， China，at the age of20to24，were selected，including the sports group and non-sports group，and each group has12people，allparticipants were on regular diet， in good condition of body， without medication record，no injury history of muscle and bone. This study used VICON infrared motion capturesystem and8sets of MX13camera to capture the kinematic data of standing long jump bythe sampling frequency is200Hz. According to the basic requirements of human anatomyand three dimensional reconstruction，39Marker（diameter is14mm）were accuratelyplaced in every point of the human body joint. Requirements:(1) to make the preparationfor5minutes， including jogging on the treadmill and basic stretch， to make the bodyjoints and muscles active till the body felt warm.(2) to make the participants complete thestanding long jump in the laboratory， to encourage them to jump longer without the appelmotions， and to complete collection for four times. Results of research: In the first and fifth step of elbow-shoulder coordination， thesports group used the normal phase coordination. In the second， third， fourth step， thesports group used the heteropical coordination， while non-sports group used normal phasecoordination. The sports and non-sports group used the normal phase coordination in thefirst and fifth step of the elbow-hip coordination， and the heteropical coordination in thesecond， third， and fourth step. Sports group used the heteropical coordination in the firstphase and fifth step of elbow-knee coordination while non-sports group used the normalphase coordination， and two groups used the heteropical coordination in other steps. Inelbow-ankle coordination，two groups mostly used the normal phase coordination， onlysports group used heteropical coordination in the second step. In the shoulder-hipcoordination，Sports group used the normal phase coordination the first step， and usedthe heteropical coordination in other steps， while non-sports group always used theheteropical coordination；Sports and non-sports group used the heteropical coordination inthe first， third， fourth and fifth step of the shoulder-knee coordination，sports group hadmore heteropical coordination in the first，third，and fifth step，the non-sports group hadmore in the fourth stage. But according to the statistical analysis， Ii was showed that therewere no significant differences between the two groups. Sports group used the normalphase coordination in the second step of shoulder-knee coordination， and non-sportsgroup used the heterogeneous coordination. In the fifth of shoulder-ankle coordination，sports group used the normal phase coordination but non-sports group used the heteropicalcoordination and there was the significant difference. Sports group used normal phasecoordination in the third step of hip-knee， but the heteropical coordination in other steps.Non-sports group used the heteropical coordination in the first and fourth step of hip-kneecoordination but the normal phase coordination in other steps. Sports and non-sports groupused the normal phase coordination in the first and the fifth step of hip-ankle coordinationbut the heteropical coordination in the second， third and fourth. Sports and non-sportsgroup used the normal phase coordination in the first step of knee-ankle coordination， butthe heteropical coordination in other steps. They were consistent.Conclusion: At the time of completing jump: sports group used more heteropicalcoordination in the elbow-shoulder coordination more， which could be more active to regulate their own action to improve the performance of long jump. There were no obviousdifferences between two groups in the elbow-hip coordination， in which the physicalexercises had no significant effect on the elbow-hip coordination. Sports group used theheteropical coordination in the first and the fifth step of the elbow-knee coordination，which could improve the performance high jump. There was no significant differencebetween the two groups in the elbow-ankle coordination. Physical exercises had no effecton the shoulder-hip coordination. Sports group used more heteropical coordination inshoulder-knee coordination， which could make better cooperation. Sports group formedstable shoulder-ankle coordination and the variability was relatively small. Sports group inthe hip-knee coordination uesd more heteropical coordination to adjust the movement toimprove the performance of long jump. Sports and non-sports group had no significantdifference in the hip-ankle coordination. In knee-ankle coordination， sports andnon-sports group also showed consistency. Thus， in the completion of standing long jump，sports group has more coordinate change，those who do the regular physical exercises，can increase the body’s ability to adapt to the environmental changes，and improve theathletic efficiency.
