Assessment methods for physical activity and physical fitness in population studies: report of a NHLBI workshop.

TL;DR: Despite extensive use over 40 years, physical activity questionnaires still show limited reliability and validity and attempts at detailed interpretation in terms of exercise dosage and the extent of resulting health benefits seem premature.

TL;DR: These observations suggest that in CHD prevention programs, regular physical activity should be promoted as vigorously as blood pressure control, dietary modification to lower serum cholesterol, and smoking cessation.

TL;DR: A physical-activity questionnaire has been developed that is both reliable and feasible to use in the Pima Indian population to evaluate the relationship of physical activity to non-insulin-dependent diabetes mellitus.

TL;DR: In this article, the authors investigated the relationship between physical activity and mortality with respect to familial aggregation of health habits during childhood and factors that may enable some individuals to achieve higher levels of fitness.

TL;DR: Ex-varsity athletes retained lower risk only if they maintained a high physical activity index as alumni, and peak exertion as strenuous sports play enhanced the effect of total energy expenditure.

TL;DR: A questionnaire for evaluating energy expenditure in leisure time physical activity (LTA) along with information about its validity is presented in this paper, which is valid for use in longitudinal studies in North America of the relationship of physical activity to disease, in weight control clinics and in other researches in which leisure-time physical activity is of interest.

TL;DR: New methods of quantifying the physical activity habits of communities were developed which are practical for large health surveys, provide information on the distribution of activity habits in the population, can detect changes in activity over time, and can be compared with other epidemiologic studies of physical activity.

TL;DR: Overall mortality and mortality due to cardiovascular and ischemic heart disease were inversely related to the level of physical activity for men and little correlation was noted between physical activity level (at the generally low level found) and thelevel of major risk factors.
