Effect of zone's diet modification in level of oxidative stress and performance of athletes

Abstract

This study aimed to prove which modification of Zone diet can improve the performance of athletes and may reduce levels of oxidative stress in the body of the athlete, especially a sprinting athlete. Used draft "Randomized Control Group Pretest Posttest Design". The 20 sample taken from people who has the criteria for inclusion and exclusion of 30 athletes sprint teenagers Persatuan Atletik Seluruh Indonesia (PASI) East Java. This study used an experimental method and observation. Data collected by result of running measurement technique using finish camera and laboratories to determine activity levels of oxidative stress (MDA) in the blood. Data were analyzed with multivariate techniques (Manova) method Hotelling's (T2). Data analysis included descriptive analysis, data normality, homogeneity of variance and analysis Manova form Paired Comparisons Hotelling's method (T2). Hypothesis testing using α 0.05. Result and conclusion of the study, that the normal diet had no effect on the variable performance of athletes and level of oxidative stress (MDA). While modification Zone diet can lowering the level of oxidative stress(MDA) minimum 0,0371 μml and an average reduction of level of oxidative stress caused modification Zone diet at least 0,010 μml lower than normal diet but no effect to performance of athletes.
