Purpose: To evaluate the recovery time of biochemical changes of body after half-course marathon running. Materials and methods: Thirteen amateur half course marathon runners (12 males and 1 females) were studied. Their average age was 44 years old (range: $38{\sim}54$). Biochemical parameters with blood test including AST, ALT, CK-MB, Treponin, BUN, Cr Na, K were evaluated at finish line, 2nd days, 2nd weeks after running. Results: All the biochemical changes were within normal range throughout recovery time, AST reached its maximum level at finish line and continued until 2nd day after running and returned its pre-running level at 2nd week's test. CK-MB reached its maximum level 2nd day after running and recovered at 2nd week's test. Na, K, BUN and Cr reached to the maximum level at finish line, and recovered to pre-running level at 2nd day's test. Conclusion: In case of half-course marathon, the changes of the kidney enzymes due to dehydration were recovered after 2nd day. And the biochemical indicators of muscle fatigue recovered after 2nd week. It needs at least 2 weeks rest after half-course marathon to recover all the biochemical parameter of the body.

The purpose of this study was to identify differences in records for each section of the wheelchair marathon and to provide information necessary for training and basic data for developing training methods. The subjects of this study were analyzed for the records of a total of 5 foreign male athletes and 4 domestic top athletes who completed the 42.195km full course among the participants at the 2016 Seoul International Wheelchair Marathon. Every 5km section records and finish records were used, and the first section to the ninth section were set. As for the data processing method, descriptive statistics (Mean, SD) were used using the statistical program SPSS 25.0. The following conclusions were drawn according to the above research methods and procedures. In the case of the winning W1 athletes, the record at 30km to 35km was the fastest 8 minutes and 43 seconds in the entire section, and the difference was 1 minute and 4 seconds compared to the K1 athletes of the nation's No. 1 athletes. In order to be ranked higher in international competitions, training to adapt to a quick pace at a later stage is required. That is, it was found that the second half face should be faster based on the half distance. In addition, in each section of the first half, it is necessary to develop a race pace suitable for the average speed level for each individual section. Therefore, it is considered that the fitness training program that can maintain the early race and the training program that can cope with changes in pace after the second half should be applied.
