Abstract :VUeut iyerisindeki metaboliklerle bir ili~ki iyindc bulunan yOl'gunlnk, performansm sInJrlayJCl faktorUdiir. Yorgunluk oldukya kompleks bir kavram olarak kaqJmlZa yJkmaktadlr. Bu kavramln hem fizyolojik hem de psikolojik bir boyutunun da oldugu bilinmektedir. Sporlif aktiyjteler slrasmda vUcudun sistemlerine dii~en awrl1kta yapllan aktivitenin Wrtine gorc artmaktadlr. Yorgunlukta, j~i yapan kaslar kadar bunlan hal'ekele ge<;iren sinir sisteminin de roW yok bUyiikttir. Yorgunlugun olu~um scbeplerini iki ana ba~hkta toplayabiliriz. 1-Metabolik Sebepler: Kastaki fosfokreatin konsantrasyonunun tUkenmesi, kaslarda proton birikimi, glikojenin kan ve kastaki miktannda azalmaJtLikenmesi, plazmadaki serbest LripLofan oranlnlO aminoasit kemiklerinin oranwa yUkselmesi. sinir kas noktalan ve sinapslarda gereksiz asetilkolin (Ach) sentai, beyin sinir hticrelerinin yorgunlugu, kandaki kaLekolaminlerin miktanndaki azalma, elektron ve su kayhl. 2- Psiko-Sasyal Sebcpler: Ki~isd faktorler, psikolojik faktorler ve <;evresel faktorler. Anahtar KelimeJer : Yorgunluk, ATP, Cpo   Summary FatJgue has acted negative on performance and it is relation in the body metabolics.

Nerve system has an important role in falJgue as body muscles since if stimulates them. There are two different reasons for fatlgue: 1· Metabolic Reasons : concentration of phosphocreatine in exhausted in tbc 'muscle, accumulation of proLon in the muscle, the decrease of glieojen level in the blood. and muscle. tbe increase of the free triptophan level unLil] amino acid bone level, unnecessry synthesis acetilcholin (Ach) in the synaps and the point of nerve muscle, the reduction of catekolamine level in the blood, dehidration and losses of the electrons. 2- Psycho-Social Reasons ; Personnel factors, psycbological factors, psychological factors and enviromental factors.
