Abstract:
Endurance in sports is usually looked upon as the ability of an athlete to tolerate fatigue. This ability corresponds largely with the effective functions of heart and lungs. The higher capacity to deliver and utilize oxygen indicates a more efficient cardio respiratory system; therefore it is essential to prolonged vigorous exercise. The purpose of the study was to examine the relationship of distance running ability and cardiorespiratory endurance among school boys. To achieve this purpose, forty students were randomly selected as subjects who were from the school at age between 13 to 14 years. Cardiorespiratory endurance was measured using Harvard step test, and running ability was measured by 4min, 8min, 12min continuous run. The study was formulated by static group design and statistically analyzed by the Pearson’s product correlation Scatter gram method. The ‘r’ was statistically tested for significance at the level of 0.05 level of confidence. The obtained correlation values 0.94, 0.91 and 0.91 are higher than the required value for significance at 0.05 level is 0.304. The result reveals that there is a significant relationship existed between distance running ability and cardiorespiratory endurance among school boys. In graphical method, a linear regression line was used for analyzing the relationship of distance running ability and cardio respiratory endurance. It also appeared that the longer the running distance, the higher its degree of relationship of Physical Efficiency Index.
