| ABSTRACT | |||
| The purpose of this study was to develop a standardized and externally
paced field test (15-m Incremental Shuttle Walk and Run Test [15mISWRT]),
incorporating an incremental and progressive structure, to assess aerobic
fitness in middle-aged adults. 68 middle-aged men performed three tests
in random order between one to two week intervals: 15-m ISWRT, cardiopulmonary
exercise test (CPX), and 1500-m fast walk. Variables evaluated were 15-m
ISWRT performance (distance completed), VO2max
measured by CPX, 1500-m fast walk performance (walking time), and HR response
in 15-m ISWRT and 1500-m fast walk. Validity of the 15-m ISWRT was tested
by comparing the associations among the 15-m ISWRT performance, VO2max
and the 1500-m fast walk performance. Changes in HR response during the
15-m ISWRT and the 1500-m fast walk were also compared. Correlations between
each variable were as follows: the correlation between 15- m ISWRT performance
and VO2max
was very high, r = 0.86 (p < 0.01), the correlation between the 1500-m
fast walk and VO2max
was r = ?0.51 (p < 0.01). HR response during the 15-m ISWRT gently increased
initially, whereas HR response during the 1500-m fast walk rapidly increased
from the start. In conclusion, our findings indicate that the 15-m ISWRT
is valid and safe for evaluating VO2max
in middle-aged adults. Key words: Maximal oxygen uptake, heart rate, 20m shuttle run test, shuttle walking test, cardiopulmonary exercise test. |
