The influence of exercise duration and cognitions during running on feeling states in an indoor running track environment

Objectives. To examine the influence of different durations of aerobic exercise and cognitions during running on exercise-induced feeling state changes in an indoor running track environment once baseline differences in feeling states were controlled.Method. Physically active females (n=69) participated in one of three experimental conditions: a) a 25 min run at 70% heart rate reserve (HRR), b) a 40 min run at 70% HRR, or c) a 40 min no exercise control. Pre-post feeling states (EFI) were assessed and cognitions during running were recorded with 5 min left in the run.Results. Multilevel modeling analyses revealed that positive engagement and revitalization significantly increased from pre- to post-exercise in comparison to the control condition regardless of exercise duration whereas physical exhaustion was significantly reduced. However, tranquility significantly increased only in the 25 min run condition. Finally, cognitions during exercise moderated the changes in feeling states from pre- to post-exercise above and beyond exercise duration with participants reporting dissociative-external thoughts reporting greater increases in revitalization and decreases in physical exhaustion.Conclusions. Both objective demands of the exercise task (i.e., exercise duration) and subjective intrapsychic phenomena (i.e., cognitions during running) may aid in explaining exercise-induced feeling state changes.     

The affective interval: An investigation of the peaks and valleys during high- and moderate-intensity interval exercise in regular exercisers

Evidence supports the notion that people generally feel worse during high(er) intensity exercise but experience an affective rebound immediately following cessation that often exceeds pre-exercise feeling states. Considering rest/recovery is an integral part of interval exercise, it is of interest to determine the degree of affective reactivity and recovery that may occur during interval exercise of different intensities. The purpose of the present study was to examine affective reactivity to and recovery from an acute bout of moderate-intensity (MIIE) and high-intensity interval exercise (HIIE). Participants (N = 25, 13 females, 23.3 ± 4.0 yrs, BMI = 25.7 ± 4.1 kg m⁻²) completed 4 sessions at the same time of day with at least 24-h between each session: a baseline session to record resting affect, a graded exercise test on a stationary bike (cycle ramp protocol 25 W·min-1) to volitional exhaustion, and then completed a high- (HIIE) and moderate-intensity interval exercise (MIIE) session where affect was recorded prior to, during, and up to 30-min post exercise. Participants reported more negative feeling states during the HIIE session compared to the MIIE session, but these states recovered similarly as early as 5-min post-exercise. In addition, while affective change (reactivity and rebounds) were relatively equal during the MIIE, declines in affect during the HIIE outweighed the affective rebounds associated with rest, resulting in a large decline in affective state from pre-exercise.     

Self-Efficacy Relationships With Affective and Exertion Responses to Exercise1

This study examined the relationship of preexisting efficacy for exercise with perceptions of effort expenditure and in-task affect during exercise testing. Subjects comprised sedentary, middle-aged adults participating in a submaxi-mal cycle ergometer-graded exercise test. Perceptions of efficacy were assessed prior to and following exercise testing while perceptions of effort expenditure and in-task affect were assessed at 70% of predicted maxim heart rate. Highly efficacious subjects had lower perceptions of effort expenditure and reported more positive affect during exercise than did their less efficacious counterparts. Affective responses during exercise were in turn significant predictors of posttest self-efficacy. These results are discussed in regard to the importance of examining the role of personal efficacy in the formation of exercise-related affect and affective responses as sources of efficacy or competence information in exercise.     

Examination of the Relationship Between Self-Efficacy and Affect at Varying Levels of Aerobic Exercise Intensity

Although proposed as an explanation for increases in positive and decreases in negative affect, little evidence supports the notion of a stronger efficacy-affect relationship as acute aerobic exercise intensity increases. Relationships between self-efficacy (SE), positive affect (PA), and negative affect (NA) were examined with respect to 3 randomly assigned conditions: (a) no exercise (control), (b) cycling at 55% VO_2max, and (c) cycling at 70% VO_2max. Twenty subjects (age = 22.6 years; M VO_2max= 47.8 ml · kg⁻¹· min⁻¹) participated in each. Preexercise SE predicted in-task NA and postexercise PA in the 55% condition and postexercise PA in the 70% condition ( ps < .05). Although SE significantly increased from pre- to postexercise, in-task affect failed to predict these increases in SE. These data suggest that in a fit college-aged population, a stronger reciprocal relationship between preexercise SE, in-task affect, and postexercise SE does not exist with increasing levels of exercise intensity. Contrary to self-efficacy theory, no evidence was found for a reciprocal relationship. However, the relationship between efficacy and affect was such that when collapsed across conditions and time, subjects with higher SE scores reported lower NA ( p < .05).     

Contributions of acute bouts of vigorous physical activity to explaining diurnal variations in feeling states in active, middle-aged women.

This study describes diurnal variations in feeling states in 84 women as a function of involvement in physical activity. Women completed feeling state checklists before and after bouts of vigorous physical activity that lasted a minimum of 20 min and on a stratified random-sampling protocol in response to a stimulus from an electronic pager. Participants self-reported the date, the time of day, the stimulus for responding, their current feeling states, and their ongoing activity. A total of 7,295 complete mood and activity reports were recorded in response to pager calls that were further coded into experience samplings that occurred on a nonexercise day, prior to exercise on an exercise day, and following exercise on an exercise day. Multilevel modeling analyses showed that in samplings recorded following exercise on exercise days, positive engagement, revitalization, and tranquility were elevated in comparison with predicted diurnal patterns.     

Exercise environment,self-efficacy,and affective responses to acute exercise in older adults

Abstract

Increasing evidence suggests that regular physical activity can have considerable psychological, as well as physical, benefits in the elderly. Although factors such as exercise dosage may be implicated in exercise-induced affect responses, it has also been suggested that social and psychological factors might influence this relationship. This study examined the roles played by exercise environment (group versus alone) and self-efficacy in affective change in 80 older adults (M age = 66 yrs) over the course of three acute exercise bouts. Using latent growth curve methodology and statistically controlling for duration and intensity of exercise, we were able to demonstrate that social (group) environments resulted in statistically significant improvements in feeling state responses when contrasted with a condition in which the participants exercised alone. In addition, increases in self-efficacy were associated with more positive and less negative feeling states. Environmental factors that might influence the exercise-affect response are discussed and recommendations for subsequent exercise, efficacy, affect research made.     

Self-Efficacy and Adherence to Exercise During and as a Follow-Up to Cardiac Rehabilitation

We examined self-efficacy (task, in-class, and barrier) and physical activity during transition from hospital-based cardiac rehabilitation. Participants ( N  = 50) completed measures of self-efficacy at the midpoint and end of the program. Cardiac rehabilitation adherence was monitored and physical activity assessed by telephone interview 6 and 12 weeks post-program. Mid-program barrier self-efficacy predicted adherence ( R ²_adj. = .15, p  < .05). Barrier self-efficacy at the end of the program predicted physical activity 6 weeks later ( R ² = .11, p  < .05). Task self-efficacy at the end of the program predicted home-based exercise at the 12-week follow-up ( R ² = .10, p  < .05). Results have implications for intervention efforts to ease transition from supervised to independent home-based exercise.     

Changes in mood caused by staged, moderate physical activity]

This experiment provides a test for the common sense knowledge that moderate physical exercise leads to mood improvement. Furthermore, it was tested whether light exercise intensifies negative feeling states or alleviates them. 30 female and 30 male students of psychology served as subjects (mean age 25.3 years, SD = 4.8). After being exposed to a mood induction procedure designed to elicit either a positive or negative feeling state, the subjects had to pedal a bicycle ergometer with 0, 50 or 75 Watt load. Cardiovascular variables and self-reports of mood states were assessed during a baseline period, after the mood induction, following the ergometer exercise, and after a follow-up period. The mood induction procedures were successful, but only for a short duration. Physiological activation was observed according to the ergometer loadings. Moderate physical exercise led to an increase of positive feeling states (Concentration) and a decrease of negative feeling states (Tiredness) in the follow-up period. Corresponding changes in tension related states could not be observed, probably due to the weakness of the mood induction procedure employed and the low level of energetic activation reached.     

Psychological States Following Resistance Exercise of Different Workloads

This experiment was designed to examine the effect of resistance exercise of different workloads on subsequent psychological states. Participants, 54 undergraduate students (34 male, 20 female), were randomly assigned to one of three groups: (a) low workload resistance exercise (50% of 1 RM), (b) high workload resistance exercise (80% of 1RM), or (c) a no exercise control. Resistance exercise consisted of three sets of five repetitions for three free-weight exercises: the bench press, overhead press, and dumbbell row. Psychological state was indicated by the Exercise-Induced Feeling States Inventory (Gauvin & Rejeski, 1993) and was assessed prior to exercise and at 10, 25, and 40 min post exercise. Data were analyzed via a 3 (group) x 4 (time) ANOVA with repeated measures on the second factor. All exercise participants experienced an increased sense of revitalization, which persisted for a greater extent in low rather than high workload participants. None of the groups reported changes over time in positive engagement or tranquility. In addition, while exercise groups did report a reduction in physical exhaustion during recovery, this improvement did not differ from no exercise controls nor did it differ between exercise groups. Thus, weight lifting appears to result in a sense of revitalization, an effect whose duration may be impacted by exercise workload.     

Exercise Stage of Change and Self-Efficacy in Primary Care: Implications for Intervention

Multiple chronic diseases are caused or complicated by a sedentary lifestyle. Thus, an important and challenging application of psychology in clinical settings is changing the behavior of sedentary primary care patients. This study focused on exercise stage of change and self-efficacy in a sample of adult family practice patients recruited while waiting for their scheduled physician appointment. Regarding exercise stage of change, 15% of respondents were in the Precontemplation stage, 26% in the Contemplation stage, 50% in the Preparation stage, 7% in the Action stage, and 13% in the Maintenance stage. Mean self-efficacy scores for exercise were significantly higher among respondents in the Action and Maintenance stages of change. These cross-sectional data are consistent with the hypothesis that movement through the exercise stages of change could be encouraged by clinical interventions that increase exercise self-efficacy. The identification of multiple personal opportunities for increasing exercise self-efficacy may be clinically useful in this context. Recommendations for psychologists in primary care settings in their work with physicians are offered.     

Visual threat detection during moderate- and high-intensity exercise

The aim of the study was to assess performance on a visual threat-detection task during concurrently performed vigorous exercise on a cycle ergometer. Thirty (15 female) participants completed a baseline condition of seated rest and then moderate- and high-intensity exercise. Moderate- and high-intensity exercise conditions were completed on the 2nd day in a counterbalanced order. During each exercise condition, participants responded to 3 × 3 picture matrices (256 trials in each condition) that contained discrepant fear-relevant and discrepant fear-irrelevant pictures (?hman, Flykt, & Esteves, 2001). Response accuracy was significantly greater, and reaction time was significantly faster, during moderate- and high-intensity exercise compared with the rest condition (ps < .001). The discrepant fear-relevant matrix type was detected significantly more accurately than a discrepant fear-irrelevant matrix (p < .001). The discrepant fear-relevant matrix was detected significantly faster than all other matrix types (p < .001). These results suggest that exercise at a moderate and high intensity may enhance the efficiency of visual detection of both threatening and nonthreatening targets.     

Post-Exercise Affect: The Effect of Mode Preference

It has been suggested that the performance of preferred modes of exercise will serve to maximize the affective response to exercise. Support has come from work that has shown the effect of exercise on affect to be mediated by enjoyment. However, there is a need to compare modes of exercise that differ in preference and enjoyment, yet are similar in intensity, duration and muscle group. This experiment was designed to achieve this aim. Thirty-four college-aged women completed 20 minutes of exercise on high and low preference modes of continuous exercise. Intensity was maintained at 65–75% of HRR. Affect was measured by the PANAS, collected prior to and at 5, 20, and 40 min post exercise. Results provided partial support for the hypothesis as mode preference moderated the improvement in positive affect, with no effect on the reduction in negative affect. Interestingly, regardless of mode preference, enjoyment ratings were found to mediate the change in both positive and negative affect.     

Increasing Positive Health Behaviors in Adolescents with Nutritional Goals and Exercise

Research has documented that low-income urban youth are at risk for obesity and related health problems. Our goal was to develop a brief, developmentally informed intervention to increase positive health behaviors (e.g., diet and exercise) among low-income, minority adolescents. Our study was designed to examine the feasibility and potential impact of our single session intervention that was delivered in a primary care setting. The participants were 100 adolescents from an urban adolescent medicine clinic who were randomly assigned to one of two conditions: a) a 3–5?min goal-only session or b) a 15–20?min motivationally enhanced intervention. Health behaviors and individual characteristics (i.e., autonomous motivation, self-efficacy) were assessed at baseline and re-assessed at follow-up 1 month later with 53?% of the youth completing the follow-up assessment. Those in the enhanced intervention group were more likely to participate in the follow-up as were those who reported higher baseline motivation and self-efficacy. Both groups reported statistically significant health behavior improvements over time and older adolescents reported more improvements. The two conditions did not significantly differ in reported health improvements. Self-efficacy predicted improvements in self-reported fruit and vegetable intake at follow-up. Results support that a brief “chat” with adolescents about their personal goals and values appears to have the potential to increase their positive health behaviors and appears to be useful as a preparatory intervention for weight management efforts for urban teens. The study demonstrates the feasibility and potential efficacy of implementing this 20?min intervention into primary care settings, thereby helping urban youth focus on their individualized goals, values, and motivations for health.     

Changes in Feeling States Following Aquatic Exercise During Pregnancy

Forty-four pregnant women participated in water aerobics 2 times per week for a period of 6 weeks, with each session lasting approximately 45 min. The hypothesis that participants would report greater feelings of positive well-being and less psychological distress and fatigue during the 6-week program as compared to preprogram reports was supported. Also supporting our hypothesis, similar improvements were noted following a single bout of exercise during each week of the program. Taken together, the results of the present study suggest that regular engagement in an aquatic exercise program is associated with improvements in positive feeling states and reductions in negative feeling states and fatigue for women during pregnancy.     

Maintenance Cardiac Rehabilitation Exercise Adherence: Effects of Task and Self-Regulatory Self-Efficacy

The purpose of this study was to examine whether self-efficacy functions as a determinant and outcome of maintenance cardiac rehabilitation exercise adherence. Specifically, the purpose of this prospective observational study was to examine which types of self-efficacy–task or self-regulatory–predicted maintenance exercise attendance. In addition, the relative contribution of self-efficacy to the prediction of perceived exercise intensity was examined. Self-regulatory self-efficacy was operationalized as confidence to schedule and manage exercise sessions, while task self-efficacy concerned confidence to perform aspects of the exercise session and to walk for increasing durations. Sixty-four maintenance cardiac rehabilitation participants completed social cognitive measures and provided attendance data for 4 weeks prior to and 4 weeks following assessment. Results indicated that scheduling and walking self-efficacy significantly predicted cardiac rehabilitation exercise attendance. Task self-efficacy was the best predictor of perceived exercise intensity. Past exercise attendance significantly predicted all 3 dimensions of self-efficacy. Findings are discussed with respect to self-efficacy theory and applications to the maintenance of cardiac rehabilitation exercise adherence.     

Effects of a Self-Efficacy Intervention on Exercise: The Moderating Role of Diabetes and Cardiovascular Diseases

The paper examines the influence of a brief tailored intervention on exercise levels and self-efficacy beliefs in the context of participants' health status. We hypothesised that the effects of a self-efficacy intervention targeting more frequent exercise would be larger among people with diabetes or cardiovascular diseases (CVD), compared to the effects of the intervention among individuals without such diseases. The treatment was tailored to participants' self-efficacy and was delivered by e-mail. Data from 187 adults were collected at two measurement points, with a 6-month follow-up. Participants reported their exercise frequency and self-efficacy scores, along with several social-cognitive variables, such as risk perception and intentions. Besides the influence of the intervention on exercise and self-efficacy, we found that the treatment effects were moderated by diabetes or CVD: Participants with those illnesses benefited from the intervention, compared to people without such diagnosis. Among participants with CVD or diabetes the effects of the intervention on behavior were mediated by changes in efficacy beliefs. The results indicated that a parsimonious treatment may contribute to change in exercise over the longer term, in particular among individuals with a disease related to the respective behavior. Changes in behavior may be explained by changes in respective beliefs.     

To see or not to see: effects of exercising in mirrored environments on sedentary women's feeling states and self-efficacy.

Effects of a mirrored exercise environment and body image concerns on changes in exercise-induced feeling states and self-efficacy were examined among 58 sedentary women (mean age = 20.7 years). Participants performed a 20-min bout of exercise in front of either a mirrored or a nonmirrored wall. Feeling states and self-efficacy were measured pre- and postexercise. Multilevel linear modeling indicated that regardless of their level of body image concern, women in the mirrored condition felt worse after exercising than women in the unmirrored condition. There were no effects of the environment or body image on self-efficacy. Results are consistent with predictions of objective self-awareness theory and have implications for promoting exercise among sedentary women.     

Motivational Readiness,Self-Efficacy and Decision-Making for Exercise1

Exercise has important health benefits, but a large proportion of the population is physically inactive. We examined the prevalence of stages of readiness to exercise and their relationship to self-efficacy and to the costs and benefits of exercising in samples of 1093 employees in and around Providence, Rhode Island, and 801 employees in Adelaide, Australia. In both samples, 40.6% of respondents had not yet begun to take action (not thinking about starting to exercise or thinking about it but not doing it), while 59.4% were at some phase of action (exercising some, starting to exercise regularly, exercising regularly). Scores on self-efficacy items and cost-and-benefit items significantly differentiated employees at extreme stages. In contrast with those who exercised regularly, employees who had not yet begun to exercise had little confidence in their ability to exercise and saw exercising as having nearly as many costs as it had benefits. There is the potential to enhance the impact of exercise interventions by targeting them so as to address factors related to these different stages of readiness to exercise.     

Why do they do it? Differences in high-intensity exercise-affect between those with higher and lower intensity preference and tolerance

Evidence suggests high-intensity exercise results in a more negative affective response when compared to moderate- or low-intensity exercise. However, a large number of individuals continue participating in high-intensity exercise, in spite of these supposed declines in affective state.PurposeDetermine whether trait differences influence variability in exercise-affect for those with higher versus lower exercise intensity preference and/or tolerance, and determine the mediating relationship between traits, exercise behavior, and affective states.MethodsUndergraduates (N = 245, 20.3 ± 1.7 yrs, BMI = 23.7 ± 3.8, 60.8% female, 82% regular exercisers) completed the Preference for and Tolerance of the Intensity of Exercise Questionnaire. They then completed a 15-min high-intensity body-weight circuit (HIC), a walk, and a reading condition, where valence (via Feeling Scale), perceived physiological activation (via Felt Arousal Scale), and ratings of perceived exertion were taken prior to, every 3-min during, and 20-min post (P20) condition, while activity enjoyment was assessed immediately post.ResultsMultivariate ANOVAs revealed significant differences (p_s < 0.05) in valence between those with high versus low intensity preferences during HIC at minutes 3 (d = 0.615), 6 (d = 0.772), 9 (d = 0.659), 12 (d = 0.625), 15 (d = 0.632), and at P20 (d = 0.554), and for enjoyment following HIC (d = 0.545), but not for walking or reading conditions.ConclusionsThese findings suggest the intensity-preference trait influences how an individual feels during high-intensity exercise, but has less influence on affect during moderate/lower intensity activities. These differences may be predictive of whether an individual will continue high-intensity exercise programming.     

Temporal relationships of self-efficacy and social support as predictors of adherence in a 6-month strength-training program for older women.

The present study investigated how self-efficacy and social support predicted adherence to a strength training program for elderly women over two time periods in the initial 6 mo. of the program. Participants were 30 elderly women volunteers aged 75 to 80 who completed measures of barrier self-efficacy and general social support at baseline and 3 mo. later. Social support from the program was also measured at 3 mo. Adherence to the program was measured by attendance. Hierarchical regression equations were utilized to identify the contributions of self-efficacy and social support for adherence at 0 to 3 mo. and 4 to 6 mo. For prediction of the first 3 mo. of adherence, both self-efficacy and social support contributed significant unique variance towards the total explained variance of 36%. For the 4- to 6-mo. period, self-efficacy explained significant (12%) variance in adherence even when controlling for the previous 3-mo. adherence. Inclusion of general social support and social support from the program, however, did not account for significant variance. Researchers must continue to examine self-efficacy and social support in exercise adherence within various time periods among older adults to develop effective intervention strategies.
