The aim of the present study was to find out the effects of 12 weeks of competitive phase specific training on basal levels of selected biochemical and haematological variables in male Taekwondo players. A total of 15 Indian male Taekwondo players (Age: 16.9 ± 1.4 years; Height: 173.5 ± 0.81 cm; Weight: 60.92 ± 11.79 kg, BMI: 20.04 ± 2.44 kg/m 2 ) were volunteered for this study. Twelve weeks of competitive phase specific Taekwondo training was given to the participants for the perfection of

... hnical skills and for the improvement of general physical conditioning abilities. Blood samples were collected from antecubital vein in the morning after overnight fasting and 24 hours of rest, both before and after training. The samples were analyzed for the selected biochemical and haematological parameters such as Lipid profile, Iron Profile, Creatine phosphokinase (CPK) Lactate dehydrogenase (LDH) and Complete Blood Picture (CBP). Data were analyzed by paired-t test by using SPSS software. A significant increase (P < 0.05) of Serum Iron, Total cholesterol, HDL-cholesterol, Hematocrit, and Mean Corpuscular Volume were observed after training. Also a significant reduction (P < 0.05) in total cholesterol/HDL-cholesterol Ratio, Lactate Dehydrogenase and Mean Corpuscular Hemoglobin Concentration (MCHC) were noted after the training. From this study it is concluded that the competitive phase specific Taekwondo training is effective for improving lipid profile and some of the biochemical parameters in national level male Taekwondo players and biochemical monitoring will be helpful for the evaluation of training effects and training related adaptations at molecular level.
