“…The validity and reliability of this test was initially thought to be a concern due to the fact that exercise intensity was determined by subjective perception only. However, the correlation coefficients • • between VO2peak or VO2AT and distance covered in 12 minutes were statistically significant, ranging from 0.72 magnitude of these correlation coefficients observed in the current study is similar to or higher than the range presented by numerous other investigators (Åstrand and Ryhming, 1954;Cooper, 1968;Fox, 1973;Glassford et al, 1965;Kline et al, 1987;Nakagaichi et al, 1996;Siconolfi et al, 1982;Tanaka et al, 1990). In addition, reproducibility of this test was very high (r=0.97, n=12).…”

“…Maximal • oxygen uptake (VO2max) and oxygen uptake • corresponding to anaerobic threshold (VO2AT) are the accepted criteria for measuring cardiorespiratory fitness and functional capacity (Farrell et al, 1979;McArdle et al, 1981;Taylor et al, 1955). However, the assessment (Åstrand and Ryhming, 1954;Cooper, 1968;Fox, 1973;Kline et al, 1987;Nakagaichi et al, 1996;Siconolfi et al, 1982). More simple and more feasible field tests of cardiorespiratory fitness have been introduced in recent years.…”

“…Some are based upon maximal performance in a field test. Other protocols have used the heart rate (HR) at submaximal work loads (Doolittle and Bigbee, 1967;Maksud and Coutts, 1971;Nakagaichi et al, 1996). However, the 12-min run/walk test has not always been practical to perform for middle age, older, sedentary, or severely deconditioned individuals because it requires a maximal or near maximal effort.…”

Abstract. The direct measurement of true maximal• oxygen uptake (VO2max) and oxygen uptake corresponding • to anaerobic threshold (VO2AT) is not always practical, especially in middle age and older populations. Therefore, the purpose of this study was to develop a simple test that could accurately estimate cardiorespiratory fitness using a submaximal treadmill walking protocol for middle age, older, sedentary individuals and patients with chronic disease. Subjects for this study were 42 men (44.9 ± 15.7 years), which included 17 patients with coronary• • heart disease (57.0 ± 9.6 years). VO2peak and VO2AT• were measured using a treadmill protocol (VO2peak; 38.4• ± 11.6 ml/kg/min, VO2AT; 22.9 ± 7.4 ml/kg/min). This simple test assessed the total distance covered in 12 minutes on the treadmill at an intensity corresponding to either 1) 11 on the Borg scale of ratings of perceived exertion (RPE11), 2) 13 on the Borg scale of ratings of perceived exertion (RPE13), or 3) "Optimal" by subjective judgment. The correlation coefficients betweenVO2peak or VO2AT and total distance at the three intensities (RPE11; 950 ± 100 m, RPE13; 1080 ± 140 m Optimal; 1050 ± 110 m) were statistically significant, ranging from 0.72 to 0.85. The test-retest reliability coefficient• on 12 subjects was 0.98. The oxygen uptake (VO2) was measured during the three walk tests on 15 subjects.• There were no significant changes in submaximal VO2 values from min 4 to min 12 (RPE11; 19.8 ± 4.7 ml/kg/ min, RPE13; 24.1 ± 4.9 ml/kg/min, Optimal; 23.1 ± 4.8 ml/kg/min) in any of the three tests. Similarly, the three
