The role of motives in exercise participation†

The aim was to better understand the role of motives in exercise participation. It was hypothesised that motives influence exercise participation by influencing behavioural regulation, and that motives are themselves influenced by personality traits. Data were from a cross-sectional questionnaire survey of 252 office workers, mean age 40 years. Analysis was by structural equation modelling. According to the final model, appearance/weight motive increased external regulation, thereby reducing participation, and also increased introjected regulation. Health/fitness motive increased identified regulation, thereby increasing participation. Social engagement motive increased intrinsic regulation. Neuroticism increased appearance/weight motive, openness increased health/fitness motive, and conscientiousness, without affecting motives, reduced external and introjected regulation. It is inferred that exercise promotion programmes, without denigrating appearance/weight motive, should encourage other motives more conducive to autonomous motivation.     

Too much of a good thing? Examining the relationship between passion for exercise and exercise dependence

ObjectivesTo examine the relationship between passion (i.e., love for an activity that is valued for which and a great deal of time is invested) for exercise and exercise dependence symptoms.DesignA cross-sectional correlational survey design was utilised.MethodA total of 480 participants (n = 275 females, n = 205 males; M_age = 18.58, SD = 1.66) completed the Leisure Time Exercise Questionnaire (Godin, Jobin, & Bouillon, 1986), the Passion Scale (Vallerand et al., 2003), and the Exercise Dependence Scale-Revised (Hausenblas, Symons-Downs, & Nigg, 2004). Path analysis using structural equation modelling was used to assess the relationships between passion and exercise dependence.ResultsPath analysis using structural equation modelling via AMOS 20.0 (Arbuckle, 2011) revealed that harmonious passion (i.e., being in control of the activity and deciding when and when not to engage in it) was positively related to the exercise dependence dimensions of time and tolerance. On the other hand, obsessive passion (i.e., an internal compulsion to engage in the activity even when not appropriate to do so) was positively related to all seven exercise dependence dimensions: time, tolerance, withdrawal, continuance, intention effects, lack of control, and reduction in other activities (CFI = .91, RMSEA = .05, SRMR = .06).ConclusionAn empirical relationship has been established to support the proposed theoretical link between passion (harmonious and obsessive) for exercise and exercise dependence dimensions.     

Sociocultural correlates of compulsive exercise: is the environment important in fostering a compulsivity towards exercise among adolescents?

Sociocultural factors hypothesised to be influential in eating disorders were assessed for their relationship with compulsive exercise. A sample of 828 adolescent boys and girls completed measures assessing sociocultural messages to change body shape as well as pressure to be thin, and also measures of compulsive exercise and disordered eating. Results showed that the sociocultural influences differed slightly between boys and girls. Hierarchical regressions showed that, after controlling for disordered eating and BMI, messages to become more muscular and media pressure to be thin significantly predicted compulsive exercise in boys, while the same regression in girls reported only media pressure to be thin as a significant predictor of compulsive exercise. These findings demonstrate the influence of the media in boys’ and girls’ compulsive exercising, as well as highlight the influence of body shape messages to become more muscular on boys’ compulsive exercise.     

Emphasizing appearance versus health outcomes in exercise: The influence of the instructor and participants’ reasons for exercise

The objectifying nature of exercise environments may prevent women from reaping psychological benefits of exercise. The present experiment manipulated self-objectification through an exercise class taught by an instructor who emphasized exercise as either a means of acquiring appearance or health outcomes. The purpose of this study was to test for interactions between the class emphasis and participants’ reasons for exercise (i.e., appearance, health) predicting participants’ state self-objectification, state social physique anxiety, exercise class enjoyment, and future intentions of returning to a similar exercise class. Results, obtained via pre- and post-exercise questionnaires, revealed a significant interaction between class emphasis and health reasons for exercise predicting state self-objectification. Participants with lower health reasons for exercise reported greater state self-objectification in the appearance-focused class compared to those with higher health reasons for exercise. Adopting stronger health reasons for exercise may buffer exercise participants from the more objectifying aspects of the group exercise environment.     

Predictors of cancer survivors’ response to a community-based exercise program

ObjectiveTo explore the degree to which sociodemographic (i.e., age, sex, ethnicity, weight status, vocational status, marital status), medical (i.e., stage of cancer, treatment status, comorbidity burden), functional (i.e., self-rated health, exercise capacity), cognitive (i.e., exercise self-efficacy beliefs), and behavioural (i.e., program adherence, extra-curricular exercise) factors predicted cancer-related fatigue and quality of life among 224 cancer survivors who participated in the community-based Wellspring Cancer Exercise Program (WCEP).DesignProspective, quasi-experimental single-group repeated measures design.MethodData on predictors and outcomes were collected using self-report and objective measures upon enrollment in the program (week 0), every 10 weeks until program completion (weeks 10, 20, 30), and at 16-weeks follow-up (46 weeks). Data were analyzed using multilevel modeling.ResultsIn general, participants who were working or transitioning to work, rated their health better, and had higher exercise self-efficacy beliefs had lower cancer-related fatigue, and those who rated their health better and had higher exercise self-efficacy beliefs had higher quality of life. Also, there was a significant interaction between time and exercise self-efficacy beliefs for cancer-related fatigue and quality of life such that greater improvements were observed among participants with higher exercise self-efficacy beliefs.ConclusionCancer survivors’ perceptions of their health and their ability to exercise should be fostered to ensure they respond positively to exercise programs in terms of cancer-related fatigue and quality of life.     

Why do they exercise less? Barriers to exercise in high-anxiety-sensitive women

Anxiety sensitivity (AS; fear of arousal sensations) is a risk factor for mental and physical health problems, including physical inactivity. Because of the many mental and physical health benefits of exercise, it is important to better understand why high-AS individuals may be less likely to exercise. The present study's aim was to understand the role of barriers to exercise in explaining lower levels of physical exercise in high-AS individuals. Participants were undergraduate women who were selected as high (n = 82) or low (n = 72) AS. High-AS women participated in less physical exercise and perceived themselves as less fit than low-AS women. Mediation analyses revealed that barriers to exercise accounted for the inverse relationships between AS group and physical exercise/fitness levels. Findings suggest that efforts to increase physical exercise in at-risk populations, such as high-AS individuals, should not focus exclusively on benefits to exercise but should also target reasons why these individuals are exercising less.     

The exercise pill: should we replace exercise with pharmaceutical means?

New physiological and pharmacological research points to the possibility of a pill that produces the complete physiological effects of exercise. Is replacement of exercise with a pill a good idea? And if so, under what circumstances? To explore answers, I have examined three approaches to the understanding exercise. From a dualist point of view, exercise is explained mechanistically in terms of physiological cause and effect relationships. From this perspective, and in particular for reluctant exercisers, there seems to be no strong argument against the use of a pill. From a phenomenological point of view, exercise is understood from a first person perspective focusing on experiential qualities. It is argued that a pill can never replace the embodied, experiential values of exercising and their potential ethical significance. In other words, the use of a pill is rejected. From a critical social constructivist point of view, exercise is understood as an expression of sociocultural values. Exercise can be a source of both bodily alienation and embodied self-realization and meaning. It is argued that in settings of alienating exercise malpractice, an exercise pill can be a temporary lesser evil approach. It is pointed out, however, that the long-term solution to malpractice is not a pill but a change of practice. In a final section, the possibility of the exercise pill is contextualized in the larger, bio-ethical debate on human enhancement.     

On the role of lyrics in the music–exercise performance relationship

ObjectivesTo examine the role of lyrics on a range of psychological, psychophysical, and physiological variables during submaximal cycling ergometry.DesignWithin-subject counterbalanced design.MethodTwenty-five participants performed three 6-min cycling trials at a power output corresponding to 75% of their maximum heart rate under conditions of music with lyrics, same music without lyrics, and a no-music control. Cycling cadence, heart rate, and perceived exertion were recorded at 2-min intervals during each trial. Positive and negative affect was assessed before and after each trial.ResultsParticipants cycled at a higher cadence towards the end of the cycling trials under music with lyrics. Main effects were found for perceived exertion and heart rate, both of which increased from min 2 through to min 6, and for affect: positive affect increased and negative affect decreased from pre- to post-trials.ConclusionsParticipants pedalled faster in both music conditions (with and without lyrics) while perceived exertion and heart rate did not differ. The inclusion of lyrics influenced cycling cadence only at min 6 and had no effect on the remaining dependent variables throughout the duration of the cycling trials. The impact of lyrical content in the music–exercise performance relationship warrants further attention in order for us to better understand its role.     

Improvement of affect following exercise: methodological artifact or real finding?

The purpose of this study was to examine the "sense of relief" effect as a potential explanation for improvement of affect following exercise. The current study included male and female participants, four exercise/expectancy conditions, and assessed six dimensions of affective space. Participants were 134 undergraduates. Heart rate and affect were assessed four times: upon entering the lab, after disclosure of assigned experimental condition, immediately after exercise, and 15-min post exercise. An examination of differences between initial measures and measures taken after disclosure of condition revealed significant changes in feelings of anxiety, calmness, and tiredness, as well as heart rate. No gender differences were observed. The results support the existence of a "sense of relief" effect, but the effect is more pronounced for physiological arousal as opposed to affect.     

Does the German version of the Exercise Dependence Scale measure exercise dependence?

ObjectiveTo examine the concordance of a questionnaire-based categorization as ‘at-risk for exercise dependence’ and an interview-based diagnosis of exercise dependence.DesignOne hundred thirty four subjects answered the German version of the Exercise Dependence Scale-21 (EDS-G). They were also assessed with a structured clinical interview for exercise dependence.MethodThe congruence between the questionnaire-based categorizations of ‘at-risk for exercise dependence’ and the diagnosis of exercise dependence based on the interview was examined using κ-coefficients.ResultThe agreement between questionnaire-based and interview-based diagnoses was fair to moderate with more false positive categorization based on the EDS-G.ConclusionAssuming that a structured clinical interview allows a more accurate diagnostic categorization, the EDS-G might overestimate the prevalence of exercise dependence.     

A pilot study of women’s affective responses to common and uncommon forms of aerobic exercise

Objective: To test the extent to which participants exposed to an uncommon versus common exercise stimulus would result in more favourable affect at post-task.

Design: Experimental design. Participants (N = 120), American women aged 18–45 years, were randomly assigned to complete 30-min of either the uncommon (HOOP; n = 58) or common (WALK; n = 62) exercise stimulus.

Main outcome measures: Self-reported affect and intentions for future exercise were measured before and after the 30-min exercise bout.

Results: Analyses of covariance were run to compare post-task affect across the HOOP and WALK conditions. At post-task, participants assigned to HOOP reported more positively valenced affect, higher ratings of positive activated affect, lower ratings of negative deactivated affect, and stronger intentions for future aerobic exercise compared to participants assigned to WALK.

Conclusions: Participants who completed an uncommon bout of aerobic exercise (HOOP) reported more favourable affect post-exercise, as well as stronger intentions for future exercise, compared to participants who completed a common bout of aerobic exercise (WALK). Future work using a longitudinal design is needed to understand the relationships between familiarity with an exercise stimulus, affective responses to exercise, motivation for future exercise behaviour and exercise maintenance over time.     

Holistic movement practices – An emerging category of physical activity for exercise psychology

BackgroundExercise psychology has an interest in physical activity behaviour and the psychological dimensions of physical activity delivery and outcomes. Holistic movement practices (HMPs) can be defined as physical practices embedded in holistic philosophies of well-being. As such, they go beyond what is typically offered in exercise contexts to purposefully include mental, emotional, social and/or spiritual components. Traditional Eastern movement practices (e.g., Yoga, Tai Chi, Qigong) are examples of HMPs, but a range of lesser known “Western-born” HMPs (e.g., 5Rhythms, Biodanza) also exist. HMPs have not yet received much structured attention within exercise psychology.ObjectiveTo analyse the nature of HMPs and discuss their relevance to the field of exercise psychology, with a view to raising awareness of HMPs within exercise psychology as well as encouraging and supporting future research.ContentWe discuss what we see as commonalities among HMPs and argue that it is useful to treat HMPs as a category of physical activity for exercise psychology, not only because they are forms of physical activity but also because psychological dimensions are an integral and purposeful part of these practices. We provide a tentative conceptualization of HMP philosophies, with brief examples, and consider how exercise psychology's subfields of participation behaviour, delivery parameters, outcomes, and mechanisms are applicable to the study of HMPs. Last, we briefly explore research issues, including HMPs' multicomponent nature, selected potential mechanisms, and methodologies.ConclusionHMPs are part of the leisure-based physical activities landscape in many modern societies, and deserve attention by exercise psychologists. Their embeddedness in holistic philosophies and multicomponent nature provide unique opportunities and challenges for research in exercise psychology.     

On the stability and relevance of the exercise heart rate–music-tempo preference relationship

ObjectivesTo examine the stability of the cubic (two points of inflection) exercise heart rate–music-tempo preference relationship found by Karageorghis et al. (2011) in cycle ergometry using a different exercise modality (treadmill exercise). To advance previous related studies through the inclusion of psychological outcome variables (e.g., state attention and intrinsic motivation) and post-experiment interviews.DesignA mixed-model experimental design was employed with two within-subject factors (exercise intensity and music tempo) and a between-subjects factor (gender). The experiment was supplemented by qualitative data that were analyzed using inductive content analysis.MethodsParticipants (n = 22) exercised at six intensities (40–90% maxHRR) during which they were exposed to music tracks at four tempi and a no-music control. Music preference, affective valence, and perceived activation were assessed during the task. Immediately afterwards, an attentional focus item, the short Flow State Scale-2 and items from the Intrinsic Motivation Inventory were administered. A subsample of participants (n = 8) was interviewed using a schedule of open-ended questions.ResultsResults did not support a cubic relationship but rather a quadratic one (one point of inflection), and there was a weak association between the optimal choice of music tempo and positive psychological outcomes.ConclusionsThe range of preferred tempi for treadmill exercise (123–131 bpm) was narrower than that for cycle ergometry (125–140 bpm). Regardless of its tempo, music reduced the number of associative thoughts by ∼10% across all exercise intensities.     

Dynamic mechanisms of exercise to improve body satisfaction: Perceived or actual fat loss?

We examined the dynamic mechanisms of aerobic training (AT) and strength training (ST) to improve body satisfaction. Sixty-six participants were randomised to either the AT or ST condition and completed an 8-week intervention. Participants completed 3 weekly, 30-minute sessions of moderate intensity AT (65–75% VO₂max) or ST (65–75% 1-RM). The energy consumption of each session was approximately equivalent under both conditions. Body satisfaction, body composition, perceived fitness and exercise self-efficacy were measured at baseline and biweekly during the intervention. Exercise improved individuals' body satisfaction (p < .05). When the energy expenditures of AT and ST were equal, there was no difference in body satisfaction improvement. There were dynamic mechanisms underlying the effects of exercise on body satisfaction. Specifically, perceived fitness influenced body satisfaction improvements during the early stages of the exercise program, while changes in body composition influenced body satisfaction toward the end of the exercise program. There were sex differences in the mechanisms underlying body satisfaction. For women, perceived fat was more important in the early intervention period; for men, actual body fat was more valuable in the late intervention period. An effective strategy to improve body satisfaction is to initially target perceived fitness before focusing on changing body composition.     

Is anxiety about health associated with desire to exercise, physical activity, and exercise dependence?

There are significant gaps in the literature regarding the behavioural consequences of health anxiety. Although past research indicates that health anxiety is associated with distinctive maladaptive behaviours, such as reassurance seeking, the relationship between health anxiety and wellness-related behaviours, such as physical activity, has not been adequately examined. Given that health anxiety is associated with excessive attempts to ensure health and avoid illness, health anxiety could be potentially related to extreme physical activity, known as exercise dependence. Using the cognitive behavioural model of health anxiety as a framework, this exploratory study investigated the relationships between health anxiety, exercise desire, physical activity, and exercise dependence.Undergraduate university students (n = 144) completed a battery of online measures. Results indicated that only the perceptual component of health anxiety, namely hypervigilance to somatic symptoms, was related to exercise desire and components of exercise dependence. Implications of the findings are discussed and future research avenues are explored.     

Does personality matter in exercise participation?

This research extends previous work by demonstrating how the relationships between social cognition and exercise are influenced by different personality types. The theory of planned behaviour forms the basis of our theoretical model, and the Big Five personality framework was used to determine personality types. Data were collected from a quota sample of 512 Malaysian adults. The results suggest that an individual's personality can prevent him or her from exercising. For example, an extrovert is likely to be driven by affect and self‐confidence in their capability to exercise, and thus are more likely to participate in exercise. Those who are more conscientious (and less neurotic) feel more in control and thus possess a greater ability to exercise in comparison with their less conscientious and more neurotic counterparts. Our findings demonstrate the importance of considering personality factors in exercise research and caution us about underestimating the relationship between perceived control, attitude and its potential behavioural outcomes that could lead to a misinterpretation of its true impact. Our core contribution lies in identifying the underlying causes of social cognition differences in a moderating capacity, which has potential to yield important theoretical and practical implications. This study sets the ground for social marketers to improve their understanding of exercise behaviour and, in turn, consumer welfare. Ultimately, they could be in a better position to develop effective health intervention and educational programmes. Copyright © 2013 John Wiley & Sons, Ltd.     

The impact of exercise environments on adolescents’ cognitive and psychological outcomes: A randomised controlled trial

Exercise in natural environments can improve cognition, positive affect, and reduce psychological stress. However, it remains unclear whether these benefits are subject to a gradient effect, whereby more natural features confer greater cognitive and psychological benefits. This study examined the influence of the exercise environment (i.e., the degree of nature) on cognition, and psychological outcomes in a sample of adolescents (n = 90; mean age = 14.3 ±.05 years). Four groups were randomised to one of the following experimental conditions: a non-exercise indoor control, indoor exercise, park exercise, and exercise in a nature reserve. Participants’ self-reported their stress, affect, and vitality and completed two measures of cognition (‘Rapid Visual Information Processing’ and ‘Spatial Working Memory’) immediately before and ~6 min after exercise. All exercise conditions participated in a group-based circuit lasting ~20 min, which included a mixture of aerobic and body-weight resistance activities. Linear mixed models were used to examine changes within and between groups. The indoor group increased sustained attention accuracy compared to the park group. There were no between-group differences in working memory. The indoor and nature groups increased cognitive arousal compared to control. The park group improved in state-level vitality compared to control. The mixed-results of this research do not support our ‘nature gradient’ hypothesis, whereby cognitive and psychological outcomes would improve in accordance with the degree of nature present in the exercise environment.     

How am I doing? Performance feedback mitigates the effects of mental fatigue on endurance exercise performance

Mental fatigue induced by an earlier cognitive task can impair performance on a subsequent physical task. The current study investigated whether such performance impairment could be mitigated by performance feedback. In an experimental sequential-task design, 63 sport science students completed a series of three tasks: 5-min physical (pre-test), 20-min cognitive, 5-min physical (post-test). Participants were randomly allocated to one of three groups: feedback (n = 23), no feedback (n = 20), control (n = 20). The physical tasks, which assessed force production during a self-paced rhythmic handgrip task as a measure of physical endurance performance, were performed with (feedback group) or without (no feedback group, control group) visual performance feedback. The cognitive tasks involved either completing a 2-back memory task to induce mental fatigue (feedback and no feedback groups) or watching a didactic film (control group). Self-report measures (fatigue, exertion, vigor, motivation) were collected throughout. The 2-back cognitive task increased mental fatigue, mental exertion and general fatigue in the feedback and no feedback groups compared to the control group. Relative to the pre-test physical task, post-test endurance performance declined in the no feedback group (−14.4%) but did not change in the control (−2.6%) and feedback (−2.4%) groups. This mitigation of performance effect was not accompanied by parallel changes in fatigue, exertion, vigor, or motivation. In conclusion, visual performance feedback mitigates the negative effects of mental fatigue on physical endurance performance.     

Does the level of physical exercise affect physiological and psychological responses to psychosocial stress in women?

ObjectivesTo test the Cross-Stressor Adaptation hypothesis for females by examining whether physically exercising young women show reduced physiological and psychological stress responses to a psychosocial stressor.DesignForty-seven healthy young women with different levels of physical exercise (17 not or rarely exercising, 15 moderately exercising, 15 vigorously exercising) underwent the Trier Social Stress Test for Groups (TSST-G); physiological and psychological stress responses during and after stress induction were compared.MethodANOVAs with repeated measures were used to compare stress reactivity and recovery between the three exercise groups. Heart rate and salivary free cortisol were used as indicators of physiological stress response, state anxiety, mood, and calmness as indicators of psychological stress response. For physiological stress reactivity, the areas under the curve with respect to the ground (AUC_G) were compared.ResultsIn all three exercise groups, experimentally induced stress led to a significant rise in heart rate, cortisol, and state anxiety; mood and calmness significantly decreased. As hypothesized, the pattern of the physiological stress response differed for the three exercise groups, with lowered reactivity in the more active groups. However, the psychological stress response partly went in the opposite direction: Exercising participants reported a higher mood decrease, suggesting a dissociation of the physiological and psychological stress responses.ConclusionsThe findings suggest that the Cross-Stressor Adaptation hypothesis is also valid for young women; however, only with regard to physiological stress response. The unexpected findings for psychological stress response need to be further explored in experimental studies.
