We reared ICR mice during a growth period (3 to 10 weeks of age) and examined the effect of exercise induction, by enriching the rearing environment with obstacles such as ladders, compared to the standard environment. Environmental enrichment significantly increased the amount of exercise in both sexes (P<0.01). Enriched exercise mice had higher body weight than control mice at 6 to 9 weeks of...

The dual-mode theory proposes that affective responses to exercise are governed by the interplay of factors influenced by the metabolic demands of exercise intensity. This paper highlights methods and mechanisms that are central to the theory and presents evidence to demonstrate the shift in affective responses, from pleasure to displeasure, as the intensity of exercise increases and causes dis...

OBJECTIVE Long, uninterrupted bouts of sedentary behavior are thought to negatively influence postprandial glucose and insulin concentrations. We examined the effects of a 1-h bout of morning exercise versus intermittent walking bouts of short duration on glucose excursions and insulin secretion over 12-h. MATERIALS/METHODS Eleven young, obese individuals (18-35 years, BMI>30kg/m(2)) with imp...

The Research Institute aims to bridge the evidence gap between traditional laboratory based ‘exercise is medicine’ research and real world interventions. This is achieved by conducting research assessing the effectiveness of interventions on directly measured physical activity levels, clinically relevant markers of cardiovascular and metabolic health, and other core variables in real world inte...

This experiment examined the effects of a possible selves intervention on self-regulatory efficacy and exercise behavior among 19 men and 61 women (M age = 21.43 years, SD = 3.28) who reported exercising fewer than 3 times per week. Participants were randomly assigned to a control condition, a hoped-for possible selves intervention condition, or a feared possible selves intervention condition. ...

PURPOSE/OBJECTIVES To examine the demographic, medical, and social-cognitive correlates of adherence to a presurgical exercise training intervention in patients awaiting surgery for suspected malignant lung lesions. DESIGN Pilot study, single-group, prospective design with convenience sampling. SETTING Exercise training was performed at a university research fitness center in western Canada...

Twin studies have estimated the relative contribution of genes and the environment to variance in exercise behavior and it is known that parental education positively affects exercise levels. This study investigates the role of parental education as a potential modifier of variance in exercise behavior from age 7 to 18 years. The study is based on large datasets from the Netherlands Twin Regist...

The central goal of modern science that evolved during the Enlightenment was the empirical reduction of uncertainty by experimental inquiry. Although there have been challenges to this view in the physical sciences, where profoundly indeterminate events have been identified at the quantum level, the presumption that physical phenomena are fundamentally determinate seems to have defined modern b...

The purpose of this article was to assess the overall health behaviors of African American emerging adults who live in a Midwestern city. Two hundred participants, ages 18-25, completed a 129-item survey. Results indicate that African American emerging adults are engaged in relatively healthy behaviors (i.e., physical activity, low substance use). The results also showed that within the emergin...
