Validity of Cooper’s 12-minute run test for estimation of maximum oxygen uptake in male university students

Abstract

The present study was conducted to validate the applicability of Cooper's 12-minute run test (CRT) for predicting VO2max in male university students of Kolkata, India, to bypass the exhaustive and complicated protocol of direct estimation of VO2max. Eighty-eight sedentary male university students recruited by simple random sampling from the University of Calcutta, Kolkata, were randomly assigned to the study group (N = 58) and the confirmatory group (N = 30). VO2max of each participant was determined by the direct procedure and the indirect CRT method. The mean value of predicted VO2max (PVO2max) (42.8±4.0 ml · kg−1 · min−1 with a range of 33.7–50.9) showed a significant difference with VO2max (39.8±4.0 ml · kg−1 · min−1 with a range of 33.5–47.7) in the study group. Limits of agreement between PVO2max and VO2max were large enough (0.10 to 5.94 ml · kg−1 · min−1) with poor confidence intervals indicating inapplicability of the current protocol of CRT in the studied population. The prediction norm [Y = 21.01X – 11.04 (SEE = 0.193 ml · kg−1 · min−1)] was computed from the significant correlation (r = 0.93, P < 0.001) between distance covered in CRT and VO2max. Application of this norm in the confirmatory group revealed an insignificant difference between PVO2max and VO2max. The modified equation is recommended for application of CRT as a valid method to evaluate the cardiorespiratory fitness in terms of VO2max in sedentary male Indian youth.

Active Children Through Individual Vouchers Evaluation: A Mixed-Method RCT

“…All teenagers in Year 9 took part in the Cooper Run Test 27 in the schools during physical education lessons. This was a 12-minute walk/run test where teenagers were instructed by the research team to complete as many laps of their school's sports hall as possible in the time.…”

“…16 The questionnaire consists of 19 items relating to 5 subscales: amotivation, external regulation, introjected regulation, identified regulation, and intrinsic regulation. 27 Its validity and reliability has been tested in several populations. 35−37 To gain an insight into the degree of autonomy individuals had for being physically active, the Relative Autonomy Index was calculated; this index has been used in similar studies.…”

New prediction models for the maximal oxygen uptake of collegeaged students using non-exercise data

“…The most accurate method to assess VO2max is directly measuring the oxygen uptake during graded, maximal exertion exercise on a treadmill or cycle ergo meter in the laboratory (Hunn, Lapuma & Holt, 2002;Eler, 2016). However, this technique requires expensive laboratory equipment, a great deal of time, continuous medical supervision and highly motivated subjects (Bandyopadhyay 2013;George et al, 2009). …”

Comparative Study on Effect of Breathing and Aerobic Exercise on General Health in Asymptomatic Population

“…Skin fold thickness was measured by skin fold calliper at subscapular region, supra-iliac region and abdomen, after that sum of the skin folds was calculated which reflects absolute or percentage changes in body fat [21]. VO 2 max (ml/kg/min) was measured using " Cooper 12 Minute Walk test", total distance was recorded in meters they had travelled in 12 minutes then it converted in kilometre and put it in the formula: VO2 max = (22.351 x kilometres) -11.288 [22,23]. In order to determine health related quality of life RAND 36 -Item health survey 1.0 scales was used.…”
