Abstract The purpose of this study was to investigate the reproducibility and utility of a standardised and externally paced field test (15-m Incremental Shuttle Walk and Run Test [15 mISWRT]) to assess aerobic fitness in middle-aged adults. 14 middle-aged participants performed the 15-m ISWRT 3 times within one week (Test 1, Test 2, Test 3). Reproducibility of the 15-m ISWRT was tested by comparing 15-m ISWRT performance (distance completed), HRmax, and VO 2max for each test. The utility of the 15-m ISWRT for evaluating VO 2max over a wide range in middle-aged adults was tested by comparing the range of VO 2max obtained from the portable expired gas analyzer with the VO 2max reference values and ranges for health promotion published by Japan's Ministry of Health, Labour and Welfare. A multiple comparison of distance completed in the 15-m ISWRT Test 1, Test 2, and Test 3 found no significant difference between Test 2 and Test 3. The ICC was 0.99 for Test 2 vs. Test 3. VO 2max measured from the 15-m ISWRT in Test 3 had a minimum value of 22.8 ml/kg/min and a maximum value of 38.7 ml/kg/min. In conclusion, the 15-m ISWRT is reliable and useful for evaluating VO 2max in middle-aged adults. © Georg Thieme Verlag KG Stuttgart · New York.
