Effect of Muscular Endurance Improvement on Prolactin and Adreno Corticotrophic (ACTH) Hormones and the Skill Performance's Level of the Kata for Karate Players

The research targeted to identify the effect of the muscular endurance (dynamic and static) on Prolactin and Adreno - Corticotrophic (ACTH) hormones and the skill performance's level of the international kinetic unit for karate players. The researcher used the experimental method on a sample of 12 students in the fourth grade specialized in karate in Faculty of Physical Education for Girls, Zagazig University and they have got the black belt (first grade) DAN (1) at least and they represent the elected karate team of Zagazig University and they are registered in the Egyptian karate federation. The researcher did some biochemical measurements, took blood samples, made physical tests and measured the level of skill performance in KATA under consideration.The suggested training program affected the dynamic and static muscular endurance for the karate players in a positive way ( the arms' muscles endurance,the abdominal muscles endurance , the back muscles endurance and the legs' muscles endurance).and The development of the dynamic and static muscular endurance affected positively the increase of the rates of Prolactin and Adreno - Corticotrophic hormones in blood for karate players.The development of the dynamic and static muscular endurance affect positively on the skill performance level of the international kinetic units (AMBY - KANKOSHO - ANSO). Also, results indicated improvement rates for the post measurement over the pre measurement in the muscular endurance (the dynamic - the static), the concentration rate of Prolactin and Adreno - Corticotrophic hormones in blood, as well as the skill performance level for the international kinetic units KATA for karate players.
