Strength Endurance Quality Of Expernmental Research About Men Hockey Player In Shandong Province

Objective:Through the strength and endurance of speed endurance of two different types of testing projects in several different index comparison of athletes in competitive sports games, especially during the destination before a period of short fatigue athletes. This paper studies the contents of short fatigue phenomenon to this phenomenon and the strength endurance mechanism was studied experimentally, also hope to study results can guide sports training practice has certain reference and the innovative strength, endurance training methods and provide certain theoretical basis.Methods:In the11th the movement from the men hockey team selection in the eight technical level and high fitness level good athletes as subjects, strength and endurance by speed endurance of two different strength test, to athletes and the short-term exhaustion of strength endurance mechanism, and the primary testing experiment to test the indexes including:blood lactic acid (BLA), creatine kinase (CK), and blood urea (BUN) and malondialdehyde (MDA). Main USES mathematical statistic method to speed endurance experiment and strength endurance experiment to test the variance analysis, two types of physical testing whether there are differences.The results:1、After speed endurance and power endurance test, athletes blood lactate index when quiet than athletes, but increased obviously lactic acid value of400testing increased obviously.Conclusion:1、From the speed endurance and power resistance blood lactic acid value can change, short time strength endurance athletes to appear short fatigue is not caused by the accumulation of lactic acid, From strength endurance training duration analysis, short fatigue phenomenon 2、With400run after that, in short, CK strength endurance exercise time of CK values lower, muscle hasn’t reach muscle contraction of capability has occurred before the short-term exhaustion, its reason is probably not timely supply of energy, we call it "the ATP bottleneck".3、Free radicals may appear in theory is short exhaustion of athletes, but not necessarily is one of the main reasons. ATP bottleneck...
