  1. Relationship between perceptions of physical activity and health-related fitness.

    Article - En anglais

    Objective

    To assess perceptions of fitness, intensity and frequency of habitual physical activity as predictors of cardiovascular function, metabolic health and obesity.

    Design

    Cross-sectional correlational, with covariance adjustment of data for age and socio-economic status.

    Setting

    An urban community of some 250,000 people.

    Participants

    Convenience sample of healthy but relatively sedentary subjects, 172 males and 178 females aged 14-68 years.

    Measures

    Self-reports of perceived fitness, habitual activity, intensity and frequency of exercise ; standard laboratory tests of cardiovascular function (resting heart rate, PWC 150/kg, systolic and diastolic blood pressure), metabolic health (blood glucose, total cholesterol, HDL-cholesterol, triglycerides and uric acid), obesity (body mass index, skinfolds, hydrostatic body fat, and abdominal circumferences) and socio-economic status (education, job classification and income).

    Results

    In men, the strongest associations of fitness markers were with peer comparisons of fitness and activity.

    In women, such comparisons also yielded significant positive associations, but the most consistent relationships of fitness were with Godin questionnaire ratings of sweat-inducing and frequent heavy activity.

    Perceptions of intense activity were associated more with cardiovascular than with metabolic health.

    Perceptions of frequent activity (peer activity ratings, occupational walking, and the number of activities report...
