Abstract
The purpose of this study was to develop normative reference values for the modified Anaerobic Speed Test (mAST), an anaerobic capacity test that can be administered and completed on a commercial treadmill. The mAST of 15% grade has been created as one of the only protocols based on the original AST protocol of 20% grade. However, no percentile norms currently exist for this protocol, limiting its usefulness and interpretation of results. This paper presents normative values for active healthy adults ages 18-29, separated by sex. The sample consisted of 276 active healthy volunteers (161 men and 115 women). All mASTs were completed on a motorized commercial gym setting treadmill for determination of subjects’ time (seconds) and work (kJ). Time to fatigue was 47 ± 10 sec for women and 38 ± 13 seconds for men. Women fatigued at 80.8% of the total time men did (p < .05). Total work for women (12.8 ± 4.3kJ) was 57.1% of the values observed in men (22.4 ± 5.53 kJ) (p < .05). Women’s mass corrected work (0.20 ± 0.070 kJ/kg) was 71.0% of men (0.28 ± 0.06 kJ/kg) (p < .05). Normative reference value tables were generated for time and both absolute (kJ) and relative values (kJ/kg) for total work. The norms for time and total work produced from this study are considerably higher than previously developed norms and more practical because of the use of both male and female active healthy populations and the use of a commercial treadmill.
