  • G. Godin, R. Shephard
  • Psychology, Medicine
  • Canadian journal of applied sport sciences…
  • 1 May 1969
TLDR
It is concluded that this simple instrument has potential value for the assessment of leisure time exercise behavior, offering the possibility of examining changes in behavior following the implementation of health and physical fitness promotion programmes in the community. Expand
Position statement. Part one: Immune function and exercise.
TLDR
The epidemiological distinction between the generic term "physical activity" and the specific category of "exercise", which implies activity for a specific purpose such as improvement of physical condition or competition is recognised. Expand
Revision of the Physical Activity Readiness Questionnaire (PAR-Q).
TLDR
The revised wording of the Physical Activity Readiness Questionnaire has apparently had the intended effect of reducing positive responses, particularly to the question regarding an elevation of blood pressure. Expand

Data from quasi-experimental studies find support in mechanistic experiments on cognitive function, pointing to a positive relationship between PA and intellectual performance, and adding time to "academic" or "curricular" subjects by taking time from physical education programmes does not enhance grades in these subjects and may be detrimental to health. Expand

TLDR
The generally poor scientific quality of the literature on this topic precludes the judgment that interventions at worksites cannot increase physical activity or fitness, but such an increase remains to be demonstrated by studies using valid research designs and measures. Expand
