Abstract
[Purpose] The purpose of this study was to investigate the usefulness of the 15 m Shuttle Run Test (15mSWRT) as a modified 20 m Shuttle Run Test (20mSRT). [Subjects] The subjects were 19 healthy young volunteers. [Methods] The subjects performed 15mSRT and 20mSRT in a random order. The usefulness of the 15mSWRT was tested by comparson of the two test performances: distance completed and VO2 measured by a portable metabolic system. [Results] The correlation between 15mSRT performance and 20mSRT performance was very high, r=0.97. The correlation between the 15mSRT performance and VO2 was r=0.89 , and it was represented by the regression equation: VO2=0.0151 distance + 26.281. According to Bland-Altman analysis, the only proportional error was in VO2 estimated from 15mSRT and VO2 measured by the portable metabolic system. [Conclusion] These results suggest that 15mSRT is useful as a simple test of endurance capacity that can be performed over a wide range of ages including middle-aged and elderly subjects.
