당원지수 차이에 따른 탄수화물의 섭취가 축구선수들의 대사 및 운동수행능력에 미치는 영향

Abstract

This study aims to identify the effects of carbohydrate intake due to differences in Glycemic Index on soccer players’ metabolism and performance and to provide information on improving athletes’ performance. In this study, eight male soccer players studying were tested using an exercise protocol that reflects the characteristics of soccer. The subjects conducted four experiments designed by a single-blind method. The group consuming carbohydrate-electrolyte drinks was categorized as LGI (Low Glycemic Index) and HGI (High Glycemic Index), and MGI (Mixed Glycemic Index) according to the GI. In this study, respiratory gas collection and measurement were performed using a respiratory gas analyzer. RER (Respirational exertion), FO (Fat oxidation), CHOO (Carbohydrate oxidation), HR, Running time, Distance, RPE, Digestive symptoms were analyzed in the SPSS statistical program One-way ANOVA. As a result of this study showed a significant difference between Cycle 5, 6 of the LGI group RER and Cycle 5 of the FO, and a considerable difference between the running time and distance of the RTF in the MGI group (p＜.05). In addition, both LGI and MGI groups showed significant differences in Cycle 5 of RPE, and MGI groups showed substantial differences in Cycle 6 of RPE (p＜.05). The results of this study suggest important implications for sports that perform intermittent high-intensity exercise with limited recoveries, such as soccer.
