An important implication of this study is that physical education should provide an equal emphasis on developing PA habits and HRPF as both are independently associated with health in childhood. These results support other research suggesting cardiorespiratory fitness may be the only aspects of HRPF that is related to various intensities of PA (as assessed via accelerometry), across childhood. No other statistically significant associations between any aspect of fitness and any PA intensities were noted across age groups. After controlling for BMI and age, cardiorespiratory fitness accounted for 3% of variation in vigorous in PA in 4-11 year-old children and significantly predicted 23% of variance in vigorous PA in late childhood. Hierarchical and linear multiple regression analysis quantified associations between HRPF components and PA levels across childhood. HRPF was assessed using curl-ups (abdominal strength/endurance), pushups (upper body strength/endurance), PACER (cardiorespiratory fitness) and grip strength. Five day PA levels (light, moderate, and vigorous) were measured using accelerometry. A sample of 160 children, including 4-5 years (n=55), 7-8 years (n=60), and 10-11 years (n=45) old, participated in this study. There is a great deal of work that remains to make good on the “potential efficacy of exercise.The purpose of this study is to evaluate associations between physical activity (PA) intensities to aspects of health-related physical fitness (HRPF) across childhood (4-11 years). ![]() ![]() Since the publication of the evidence that came out of that NIMH workshop in Morgan and Goldston’s 1987 book, “Exercise and Mental Health,” a great deal more has been learned yet key aspects of the relationship between exercise and anxiety remain unknown. A National Institute of Mental Health “state-of-the-art workshop” in 1984 was the first significant call put forth that understanding the anxiety-reducing potential of exercise was important and required further investigation. In addition to its potential for preventing anxiety and anxiety disorders, an increasing number of studies have examined the utility of physical activity and exercise interventions for the treatment of elevated anxiety and clinical anxiety disorders. A historically popular research topic in exercise psychology has been the examination of the exercise-anxiety relationship, with an ever-growing literature exploring the link between exercise and anxiety. ![]()
