This study is an experiment to look into recovering process after maximum anaerobic exercise of career wrestlers and their basic fitness. First, group time results in anaerobic power test did not show meaningful differences between groups in PP, MP, LP field. Second, blood glucose showed meaningful difference in 5-year wrestlers group according to time-wise result (p<.001). Third, time-wise results in blood lactic acid concentration showed meaningful difference all in 5-year, 10-year and 15-year career wrestlers group (p<.001). Fourth, side step and general reaction did not show meaningful differences in all the 3 groups. In conclusion, increase or decrease was seen from and also significant differences were seen from the change of anaerobic power, glucose, lactic acid, concentration, basic physical strength reaction which have influence over athletic performance of players after anaerobic exercise. It was found that 5-year career players group was good at variables of power test and glucose. Reason why recovery capability in connection with degree of fatigue was poor in 15-year career players group seemed to have correlation between career and age.

The purpose of this study was to investigate the effective posture for air pistol shooting. Participants were 3 male athletes of shooting with at least five years of experience and another group of 3 males athletes with less than three years of experience. For the purpose, the shooting motion was analysed using three dimensional image technology. Data from each event for the two groups, competent and less competent ones, were compared to see the differences from the kinematical point of view. Time of period in competent group was longer than less competent group during the shooting posture. Displacement of center of mass and pistol about medial/lateral and antero/posterior in competent group was little than less competent group from aim to shooting. And these result were effect to the velocity. Distance and time in competent group within coaching machine were smaller than less competent group. To the result, it was appear that precision of aim in competent group was higher than less competent group.

The purpose of this study was to investigate the effect of bicarbonate intake on blood variables during high-intensity training of sprinters. 30 male/female elites with more than 3 years of experience that are registered to S city as a sprinter was categorized into three groups: control group, training group, and HCO₃^- and training group. Training group and HCO₃^- and training group went through a high-intensity exercise program (80-90% HR max) which escalated every 2-3 weeks, for 90 minutes at a time, 5 days a week, 8 weeks in total. HCO₃^- and Training group took in 300mg of bicarbonate per one kilogram of body weight, in 90 minutes before the start of the high-intensity exercise program, once a day for 8 weeks. As a result of the study, the effect of bicarbonate intake on blood variables during high-intensity training of sprinters showed a positive effect on the increase of pH and the decrease of lactic acid in HCO₃^- and training group. Also, the increase of Ca²⁺, Na⁺, K⁺ was shown in training group and HCO₃^- and training group, whereas there were no indications of significant change in Mg²⁺ in all three groups. It can be confirmed that the intake of bicarbonate during high-intensity training shows effective changes in the increase of pH and the decrease in lactic acid among changes in blood variables. Therefore, it can be seen that the intake of bicarbonate during high-intensity exercise is effective in improving exercise capacity.
