| Abstract |
This study suggests that, based on the thesis that analyzing heart rate, glucose and lactate concentration changes while training with intake of water and electrolyte drink before, middle of, after playing and during recovery time can have positive influences on body, more efficient training method for middle school kendo players. Physical characteristics of the subjects are age of 14.1±0.6, height of 169±7.6 cm, weight of 62.1±8.7 kg, total fat mass of 17.7±3.8%, played period of 6.2±1.2, VO2max value of 47.9±2.8, HRmax value of 195.2±3.1 and temperature of 28±2.5°C. The result was classified according to intake method and, first of all, changes in glucose concentration showed statisticaaly significant differences between each intake method in duplicate (p<.05), and also interaction effects. Secondly, analysis on lactate concentration showed statistically significant changes according to each intake method (p<.05). The repeat period in each group showed interaction effects and showed statistically positive changes (p<.05). Thirdly, analysis on heart rate changes showed statistically significant difference according to each intake method (p<.05) and in addition, showed interaction effects of repeated period in each group (p<.05). Therefore, it can be determined that drinking electrolyte drink while training can have positive influences on kendo players. |
