Résumé : |
Objectives To develop a fitness index unlinked to resting heart rate and suitable for clinical use, and to obtain reference values of this new index for healthy subjects. Design Cross-sectional study. Setting Research laboratory. Participants A volunteer sample of healthy subjects (N=100; 50 men; age range, 2070y) randomly recruited from the general community. Interventions Not applicable. Main Outcome Measures Participants performed a submaximal, multistage cycle ergometer test. A new fitness index, the physical working capacity at 75% of the predicted maximal heart rate per kilogram of body weight (PWC75%/kg), was calculated. Its concordance with a previously described fitness index and its relationship with age were examined, as well as differences attributable to sex and lifestyle. Reference values of the PWC75%/kg (mean + SD and 95% confidence interval) were calculated and categorized by age classes of 10 years and by sex. Results The intraclass correlation coefficient (ICC) between PWC75%/kg and the working capacity index at 65% of the heart rate reserve per kilogram of body weight (WCI65%HRreserve/kg) was very high (ICC=.96, P<.001 indicating that the fitness index can be estimated without measuring resting heart rate. pwc75 decreased as age increased. average was significantly higher in men than women and active inactive subjects> Conclusions This study presents a new fitness index, the PWC75%/kg, which is suitable for measuring fitness in active and sedentary people aged 20 to 70 years. It may also be a suitable fitness index for selected chronically ill individuals. This study also provides reference values of the PWC75%/kg obtained from healthy men and women. |
