- W2000576586 abstract "The purpose of this study was to investigate the validity and reliability of the I-mile track jog test predictions of aerobic capacity (VO2max) in African Americans and Whites. Thirty Whites (15 men and 15 women) and 31 African Americans (15 men and 16 women), ranging in age from 18 to 38 years, voluntarily participated in this study. Each participant randomly performed the 1-mile track jog test twice on an indoor track and a maximum graded exercise test on a motor-driven treadmill. Intraclass reliability analysis indicated that multiple trials of the I-mile track jog test resulted in highly and equally reliable VO2max estimates for both ethnic groups ( r > .98). A two-way analysis of variance (ANOVA) indicated that the mean I-mile track jog estimates of VO2max for Whites (46.25 6.8 ml · kg-1 · min-1) and African Americans (44.1 ± 6.0 ml · kg-1 · min-1) were similar, even though significant differences (p < .05) existed in measured VO2max between the Whites (45.1 ± 9.3 ml · kg-1 · min-1 ) and African Americans (38.2 ± 7.5 ml · kg-1 · min-1). Repeated measures ANOVA revealed that the 1-mile jog test systematically overpredicted measured VO2max in African Americans by 5.9 ml · kg-1 · min-1 (p < .0001). Although Pearson product-moment correlation coefficients r = 0.87) were equal for Whites and African Americans, further regression analysis of the data indicated that ethnicity was a significant variable in predicting VO2max. Differences existed in the standard error of estimate and total error calculated for Whites (4.5 and 4.8 ml · kg-1 · min-1, respectively) and African Americans (3.6 and 7.0 ml · kg-1 · mid, respectively). The bias revealed in this study may be due to physical or physiological differences between groups or differences in fitness levels. Results of this study suggest the need to evaluate the effects of ethnicity and fitness on the validity of other submaximal exercise tests." @default.
