摘要：Aim.The objectification technique in high jump by biomechanical analysis based on kinematic recording techniques spatiotemporal parameters correlated with parameters of labor - power ergometer,monitored and evaluated with the initial and final tests.Methods.The subjects included in this research were specialized athletes in high jump event,participants at the National Championships.We used Kistler Quattro Jump force platform and Dartfish ProSuite software in order to achieve the measurement that our research aimed.Results.F max relative value at the time of contact in the initial testing is 5.7821 w / sec,which falls to 1.91158 w/sec.Power (max DTF) in initial testing is 6.10575 W / sec with a decrease in w 2.86687.DTF max power is in final testing greatly increased by 9.19582 w / sec to 0.08 sec over DTF drops to 8.4858 min w / sec,very small loss in speed due execution confirmed recording time kinematic impulse to 0.200 sec.,which confirms the increase in power after motor training program suited to the jumper.Conclusions.The height of the jump is in a direct proportion to the improvement of labor - power snapshots / kg and in inverse ratio to the duration of the contact line.The differences between the results expressed by recording parameters in the tests are worth less,due to the characteristics of the muscle - ligament force in developing ageappropriate junior.
