Abstract:
The purpose of this study was to construct a cardiovascular test by running method by using the following formulas : Cardiovascular Efficiency = (Distance (M.) X Body Weight (Kg.)) / (Time (Minute) X Difference of Pulse Rate before and after running) and/or Cardiovascular Efficiency = (Distance (M.) X Body Weight (Kg.) X Coefficient of Friction) / (Time (Minute) X Difference of Pulse Rate before and after running) The subjects were forty younger men at the higher certificate of education level of Uttaradit Teacher College, whose average age, body weight and height were 21.03 years, 55.13 kgs. and 165.5 cms. respectively. Astrands ergometric test was used in order to find the maximum oxygen uptake capacity for use as a criterion test for comparison with the cardiovascular efficiency. Subjects were tested in 3 distance runs, namely, 800 metres, 1,200 metres, and 1,600 metres. The coefficient of correlation between the results obtained from ergometric and the cardiovascular tests as determined by running method in the 3 distances was made in order to validate the test. Retest in the three distance run was also conducted in order to determine the reliability of the test. After a week of rest. The results showed that the coefficient of friction between the track and the shoe was 0.51. The mean scores of the cardiovascular test by running 800 metres, 1,200 metres, and 1,600 metres. without taking the coefficient of friction between the track and the shoe in to account were 156.04, 154.72 and 151.08 Kg.M./Min./Pulse Rate Difference. There was no significant at the .01 level. While the coefficient of friction between the track and the shoe was taken into account, the mean scores were 78.19, 77.36, and 75.54 Kg.M./Min./Pulse Rate Difference. Again there was no significant difference at the .01 level. The coefficient of correlation between the test and retest of the cardiovascular test by running each distance was 0.95, 0.96 and 0.87 respectively, which were significant at the .01 level. This study verified that the cardiovascular test by running in each of 3 distance methods was valid and reliable. Both formulas found in this study might be used in testing the cardiovascular efficiency effectively
