OBJECTIVES Affective valence responses to exercise may influence adherence. According to a newly proposed dual-mode model, affective responses have been proposed to vary depending on whether exercise is undertaken above or below the anaerobic threshold. With the model in mind, the study objectives were to explore the impact of an above-lactate,(More)
Using a mixed-method approach, the aim of this study was to explore affective responses to exercise at intensities below-lactate threshold (LT), at-LT, and above-LT to test the proposals of the dual-mode model. These intensities were also contrasted with a self-selected intensity. Further, the factors that influenced the generation of those affective(More)
The purpose of the four studies described in this article was to develop and test a new measure of competitive sport participants' intrinsic motivation, extrinsic motivation, and amotivation (self-determination theory; Deci & Ryan, 1985). The items for the new measure, named the Behavioral Regulation in Sport Questionnaire (BRSQ), were constructed using(More)
Using self-determination theory (Deci & Ryan, 1985) as the theoretical framework, we examined potential antecedents of athlete burnout in 201 elite Canadian athletes (121 females, 80 males; mean age 22.9 years). Employing a cross-sectional design, our primary aims were to investigate the relationships between behavioural regulations and athlete burnout and(More)
BACKGROUND At exercise intensities around ventilatory threshold (VT), the extent to which individuals experience pleasure or displeasure from the exercise varies between individuals. One source of this variability is proposed to be the cognitive appraisal that occurs during the exercise which influences the generation of the affective response. When(More)
The purpose of the study was to compare affective and motivational responses to exercise performed at self-selected and prescribed intensity [close to ventilatory threshold (VT)] between physically active and sedentary women. Following a graded exercise test, the women completed two 30 min bouts of treadmill exercise (on separate days, order(More)
This study compared the effects of 20 minutes of treadmill exercise at a prescribed intensity exercise (65% VO(2)max) and a preferred intensity exercise on psychological affect and exercise enjoyment in aerobically fit individuals. Affect was measured before exercise, at 5-minute intervals during exercise and 5 minutes post-exercise. Heart rate, ratings of(More)
INTRODUCTION/PURPOSE It is important that individuals experience a positive affective response during exercise to encourage future behavior. Exercise intensity is a determinant of the affective response. Current research protocols have failed to find the intensity at which all individuals will experience this positive affective response. Consequently, the(More)
OBJECTIVE Exercise stress, immune status, and mood are interrelated. The stress of adventure racing is unique; exercise is very prolonged and competitive, with severe sleep deprivation and sustained cognitive demands, usually in arduous terrain and environmental conditions. The purpose of this prospective, descriptive study was to identify mood changes(More)
BACKGROUND Because parental recognition of overweight in young children is poor, we need to determine how best to inform parents that their child is overweight in a way that enhances their acceptance and supports motivation for positive change. This study will assess 1) whether weight feedback delivered using motivational interviewing increases parental(More)
