Influence of exercise on blood lipids and immune system in female Serbian judokas

Abstract

Training is one of the methods to improve exercise performance, but too much training and competitions cause adverse effects in biochemical and hematological parameters and affects on health state of athletes. The present study was designed to evaluate the changes in total antioxidant activity, total and differential white cell counts and blood lipids at female Serbian judokas after four week training program without weight reduction. The sample of this research consisted 9 female judokas from Serbia national team, age 23.11±3.95 years, who take a bronze medal on European team championship. Blood samples were collected to measure blood lipids, total and differential white cell counts and total antioxidant activity. Complete blood tests were done on instrument SAFIR firm Abot. Biochemical parameter has been providing on instrument ADVIA 1800 firm Bayer Siemens. Total antioxidant activity in serum were done by FRAP method. General results of study showed a significant increase in total cholesterol concentrations after second measurement (p<0.01) at female Judokas, significant decrease of HDL-C (p<0.05), and significant increase in nonHDL and LDL-C concentrations (p<0.01). In addition, decrease (p<0.05) were found in eosinophile count and increase in monocytes and basophiles after training program. This study has documented that this training program has no negative effect on total antioxidant activity of athletes without proper nutrition, but on lipid profile indicate otherwise. Therefore, beneficial adaptations in lipoprotein profile must be achieved with moderate training intensities and proper nutrition.
