The effect of competition stress on the some anaerobic oxidative enzymes and blood (ph)of young handball players

Abstract

ABSTRACT

The importance of research is to identify the response enzymes of anaerobic oxidative stress and portability muscle work , especially in the case of the concentration of lactic acid of handball players during physical stress in the competition and the extent of influence on the player's ability to compete in the state increased secretion of anaerobic oxidative enzymes ( CPK - LDH) or incompleteness when player exposed some effect on competition or increase the burden physical game or some side effects which might be exposed to the player also during competitions , hence emerged the research problem in the answer to the following question (Do competition stress during the games in the match effect on anaerobic oxidative enzymes and ph blood the handball players and result in this study for their stand on the pros and cons during the competition stress) and this research aims to identify the effect of the stress through the competition on some special anaerobic oxidative enzymes as well as to identify the effect of blood PH on young handball players .The researchers used the descriptive approach being appropriate approach to solve the problem of the research , have been identified research community and they seemed League clubs Iraqi youth handball for the season 2013-2014 , has been selected sample random method they seemed to Club Kufa 's (12) as a player , and was baptized researchers to conduct a reconnaissance for the purpose of identifying the possibility of laboratory tests ,how to take out a mechanism to obtain blood samples from the players, and then has procedures field research sample through the game 's official club team Kufa since been withdrawn blood samples before game at a time and the rest after the first half and the second half and after the existence of the medical staff , who number was equal to the number of players to ensure rapid action and lack of impact on the game and the ease of access to blood samplesTo manage the data to interpret the researcher used several statistical methods (mean, standard deviation, percentage, sprains, test f analysis of variance of the samples correlated, test (LSD) is less significant difference) In light of the foregoing, the researcher suggested, that there are differences statistically significant between rest periods and after the first half and the second
