In the past 75 years, articles in Research Quarterly for Exercise and Sport (RQES) have contributed to the understanding of the role physical activity plays in the health of individuals and populations. Articles have described laboratory and community research studies in humans and animals, presented reviews of topics and conference proceedings, and presented forums for discussion about current topics in physical activity and health. The articles reflect the growth of the profession from basic inquiry, about physiological responses to exercise (and the development of physical fitness methods and standards), to studies of the effects of exercise on physical fitness and health in various population subgroups. This evolution in RQES reflects the well recognized paradigm shift toward public health concerns for physical activity and health outcomes.
