Effects of 6 months of training prior to a major competition on hematological and biochemical parameters in young elite judoka

Abstract

This study was conducted in order to examine the effects of 6-month judo training period on maximal aerobic and anaerobic performance, hematological and biochemical parameter responses of eight internationally competitive male judokas. Judokas an average age of 15.5±0.76 years were recruited in this study. The physical measurements including body height, body weight, body-mass index, body fat percentages, cardio-respiratory performance test for measuring maximum oxygen uptake (VO2max) and anaerobic threshold, biochemical parameters and hematological levels of the judokas were analyzed both pre- and post-training season. In order to determine the hematologic and biochemical levels, blood samples (both pre- and post-training), were collected from each participant in gel tubes. The hematologic and biochemical parameters were analyzed in laboratory with using auto-analyzers. The observed increases in the post-training values as compared to the pre-training values for the cardio-respiratory performance tests (i.e., VO2max and anaerobic threshold), the hematological parameters (i.e., basophil %, neutrophil, basophil number, hemoglobin and hematocrit) and the biochemical parameters (i.e., triglyceride and high-density lipoprotein) were all significant. The decrease in the post-training values as compared to the pre training values for eosinophil % and eosinophil number were found also significant. A 6-month longterm judo training program improved cardio-respiratory performance and the hematological and changed the biochemical levels of judokas.
