Self-Paced Exercise, Affective Response, and Exercise Adherence: A Preliminary Investigation Using Ecological Momentary Assessment

David M. Williams, Shira Dunsiger, Jessica A. Emerson, Chad J. Gwaltney, Peter M. Monti, and Robert Miranda Jr.

Affective response to exercise may mediate the effects of self-paced exercise on exercise adherence. Fiftynine low-active (exercise <60 min/week), overweight (body mass index: 25.0–39.9) adults (ages 18–65) were randomly assigned to self-paced (but not to exceed 76% maximum heart rate) or prescribed moderate intensity exercise (64–76% maximum heart rate) in the context of otherwise identical 6-month print-based exercise promotion programs. Frequency and duration of exercise sessions and affective responses (good/bad) to exercise were assessed via ecological momentary assessment throughout the 6-month program. A regression-based mediation model was used to estimate (a) effects of experimental condition on affective response to exercise (path a = 0.20, SE = 0.28, f 2 = 0.02); (b) effects of affective response on duration/latency of the next exercise session (path b = 0.47, SE = 0.25, f 2 = 0.04); and (c) indirect effects of experimental condition on exercise outcomes via affective response (path ab = 0.11, SE = 0.06, f 2 = 0.10). Results provide modest preliminary support for a mediational pathway linking self-paced exercise, affective response, and exercise adherence.

Throwing the Mountains into the Lakes: On the Perils of Nomothetic Conceptions of the Exercise-Affect Relationship

Lisa M. Van Landuyt, Panteleimon Ekkekakis, Eric E. Hall, and Steven J. Petruzzello

Traditional conceptions of the exercise–affect relationship postulate that moderate-intensity exercise leads to positive affective changes in all or most individuals, and it can, therefore, be prescribed for all individuals involved in exercise programs. This study investigated whether this assumption is true, not only at the level of group averages but also at the level of individuals. Affect was assessed before, during, and after a session of moderate-intensity cycle ergometry using a dimensional conceptualization of affect. Examination of individual responses revealed a diversity of patterns that was masked by aggregate-based analyses. Mean ratings of affective valence were shown to remain stable during exercise, but in actuality almost half of the individuals experienced progressive improvement, whereas the other half experienced progressive deterioration. The diversity of individual affective responses must be taken into account in formulating conceptual models of the exercise–affect relationship and deriving public health physical activity recommendations.

Does Exercise Motivation Predict Engagement in Objectively Assessed Bouts of Moderate-Intensity Exercise?: A Self-Determination Theory Perspective

Martyn Standage, Simon J. Sebire, and Tom Loney

This study examined the utility of motivation as advanced by self-determination theory (Deci & Ryan, 2000) in predicting objectively assessed bouts of moderate-intensity exercise behavior. Participants provided data pertaining to their exercise motivation. One week later, participants wore a combined accelerometer and heart rate monitor (Actiheart; Cambridge Neurotechnology Ltd) and 24-hr energy expenditure was estimated for 7 days. After controlling for gender and a combined marker of BMI and waist circumference, results showed autonomous motivation to positively predict moderate-intensity exercise bouts of ≥10 min, ≥20 min, and an accumulation needed to meet public health recommendations for moderate-intensity activity (i.e., ACSM/AHA guidelines). The present findings add bouts of objectively assessed exercise behavior to the growing body of literature that documents the adaptive consequences of engaging in exercise for autonomous reasons. Implications for practice and future work are discussed.

Affect, Exercise, and Physical Activity among Healthy Adolescents

Margaret Schneider, Andrea Dunn, and Daniel Cooper

Many adolescents do not meet public health recommendations for moderate-to-vigorous physical activity (MVPA). In studies of variables influencing adolescent MVPA, one that has been understudied is the affective response to exercise. We hypothesized that adolescents with a more positive affective response to acute exercise would be more active. Adolescents (N = 124; 46% male) completed two 30-min exercise tasks (above and below the ventilatory threshold [VT]), and wore ActiGraph accelerometers for 6.5 ± 0.7 days. Affective valence was assessed before, during, and after each task. A more positive affective response during exercise below the VT was associated with greater participation in MVPA (p < .05). The results are consistent with the hypothesis that individuals who have a more positive affective response to exercise will engage in more MVPA. To promote greater participation in MVPA among adolescents, programs should be designed to facilitate a positive affective experience during exercise.

Correlates of Exercise Intentions in Non-Hodgkin’s Lymphoma Survivors: An Application of the Theory of Planned Behavior

Kerry S. Courneya, Jeffrey K.H. Vallance, Lee W. Jones, and Tony Reiman

In the present study we examined the demographic, medical, and social cognitive correlates of exercise intentions in non-Hodgkin’s lymphoma (NHL) survivors using the theory of planned behavior (TPB). Participants were 399 NHL survivors who completed a mailed survey that assessed demographics, past exercise, and the TPB (i.e., intention, perceived behavioral control, affective and instrumental attitudes, and subjective norm). Descriptive data indicated that only about 50% of NHL survivors intended to exercise at levels that are consistent with current public health guidelines. In support of the TPB, multiple regression analysis indicated that the model explained 55% of the variance in exercise intentions, with perceived behavioral control (β = .47), affective attitude (β = .23), and subjective norm (β = .15), being the most important correlates. It was concluded that the TPB provides a good framework on which to base interventions designed to increase exercise intentions in NHL survivors.

Some like It Vigorous: Measuring Individual Differences in the Preference for and Tolerance of Exercise Intensity

Panteleimon Ekkekakis, Eric E. Hall, and Steven J. Petruzzello

Individuals differ in the intensity of exercise they prefer and the intensity they can tolerate. The purpose of this project was to develop a measure of individual differences in the preference for and tolerance of exercise intensity. The steps involved in (a) item generation and face validation, (b) exploratory factor analysis and item selection, (c) structural validation, (d) examination of the internal consistency and test-retest reliability, (e) concurrent validation, and (f) construct validation are described. The Preference for and Tolerance of the Intensity of Exercise Questionnaire (PRETIE-Q) is a 16-item, 2-factor measure that exhibits acceptable psychometric properties and can be used in research aimed at understanding individual differences in responses to exercise and thus the psychological processes involved in the public health problem of exercise dropout.
