the relationship between blood buffer capacity and aerobic power with ability to perform high intensity intermittent activities in young football players

the purpose of this study was to determine the relationship between blood buffer capacity and aerobic power (vo2max) with ability to perform high intensity intermittent activities in young football players. methods: 27 male football players (age 17.66 ±0.49 years) selected as subjects. blood samples were collected before and after the yoyo intermittent test. then, after 48 hours, the bruce treadmill test was performed for measuring vo2max. the pearson coefficient correlation was used for analyzing data. results: a significant relationship was found between h+ , hco3 - , be and ability to perform high intensity intermittent activities (r=0.609, p=0.001; r= -0.381, p=0.050; r=-0.401, p=0.038), a significant relationship between vo2max and ability to perform high intensity intermittent activities (r=0.761, p=0.000) and no significant relationship between pco2 and ability to perform high intensity intermittent activities (r=-0.130, p=0.517). conclusion: results indicate that blood buffer capacity and vo2max are effective factors in the performance of intermittent activities in football players.
