The Effect of a 6-Week Camp Preparation on Complement System (C3,C4) in Young Professional Karate Ka

The purpose of this study was to consider the effect of a 6-week camp preparation on a few pro-inflammatory acute phase proteins (complement C3, C4) in young professional karate ka. For this purpose, 10 professional karate athletes (mean+SD weight 68±5 kg; age 20.8±2 years; height 175±4 cm and body fat 7.6±2%) were invited to the camp. Blood samples were gathered 24 hours before the camp began (Time 1), at the end of the third week (T2) and the end of the sixth week (T3). Data were analyzed by one-way repeated measures analysis of variance (ANOVA) and a Tukey post hoc test. Results showed that C3 concentration was located within the normal domain at the three stages. C3 concentration decreased during the first 3 weeks (2.56%) and returned to the normal domain during the second 3 weeks (T3), however, the variations were non-significant (P=0.712). Before the camp began, C4 concentration was within the normal domain, significantly increased after 3 weeks of camp attending (18%) and at the end of the camp, it returned to the normal domain (P=0.02). Finally, the results of this study suggested that 6 weeks of camp preparation changes the parameters of complement system (C3, C4). The results seem to be questionable in relation to the type and intensity of karate training in the camp, so further studies are necessary to discover more facts about them.
