title: Validity and reliability of the 20 meter shuttle run test in military personnel.
abstract: is regularly monitored in military personnel, as occupational demands require a certain level of fitness. Distance run (eg, 2 mile) is typically carried out to measure aerobic fitness, but an alternative test could be the 20 meter shuttle run test (20 m SRT). The present study aimed to evaluate validity and reliability of this test in military personnel. An equation for predicting maximal oxygen uptake (VO2max) was developed on 38 Home Guard soldiers and cross validated in 28 Air Force cadets. Reliability of the 20 m SRT, expressed as mean difference in estimated VO2max-- 95% limits of agreement, was -0.8 +/- 3.1 mL x kg(-1) min(-1). Mean difference +/- limits of agreement between estimated and measured VO2max was -0.4 +/- 6.2 mL.kg(-1)x min-'. The 20 m SRT seems to be a reliable test, although validity is less certain, as relatively high variability was observed between measured and estimated VO2max from the 20 m SRT.
