Exercise Is In! Implicit Exercise and Sedentary‐Lifestyle Bias Held by In‐Groups1

This research examined implicit exercise‐related bias between exercising groups. Participants (N = 53) completed an Implicit Association Test with neutrally valenced exerciser or couch potato exemplars. Participants who explicitly identified as exercisers had greater positive bias toward exercisers and against couch potatoes than did participants who identified as nonexercisers. Similarly, participants who reported greater exercise had significantly greater positive bias toward exercisers than did participants who reported less exercise. Our results expand on existing research on anti‐fat and exercise‐related stereotypes by providing evidence of implicit biases for exercisers and against couch potatoes among those who are already active.     

Self-Affirmation Reduces Biased Processing of Health-Risk Information

An experiment tested whether a positive experience (the endorsement and recall of one's past acts of kindness) would reduce biased processing of self-relevant health-risk information. Women college students (N = 66) who reported high or low levels of daily caffeine use were exposed to both risk-confirming and risk-disconfirming information about the link between caffeine consumption and fibrocystic breast disease (FBD). Participants were randomly assigned to complete an affirmation of their kindness via questionnaire or to a no-affirmation condition. Results indicated that the affirmation manipulation made frequent caffeine drinkers more open, less biased processors of risk-related information. Relative to frequent caffeine drinkers who did not affirm their kindness, frequent caffeine drinkers in the affirmation condition oriented more quickly to the risk-confirming information, rated the risk-confirming information as more convincing than the risk-disconfirming information, and recalled less risk-disconfirming information at a 1-week follow-up. They also reported greater perceived personal control over reducing their level of caffeine consumption. Although frequent caffeine drinkers in the affirmation condition initially reported lower intentions to reduce their caffeine consumption, there was no evidence that they were less likely to decrease their caffeine consumption at the follow-up. The possibility that positive beliefs and experiences function as self-regulatory resources among people confronting threats to health and well-being is discussed.     

Interactive Effects of Exercise Status and Observer Gender on the Impressions Formed of Men

The present study was designed to examine whether men and women differ in the impressions they form of men based on exercise status. Male and female participants (N?=?183) rated a male exercise or control target on both physical and personality variables. Analysis of the physical characteristics revealed a significant condition by gender interaction where male participants rated the control target as significantly less fit (as compared to the exercise target) than did female participants. Analyses also revealed exercise status main effects for both physical and personality characteristics; exercisers were viewed in a more positive light than control targets. The present findings revealed that exercise status might have differential effects on impression formation depending on the gender of the people who are forming the impression.     

Physical health correlates of overprediction of physical discomfort during exercise

This study sought to determine if overprediction of physical discomfort prior to and following exercise was related to a number of self-report and objective measures of physical health status in a general population sample. Cross-sectional findings indicated a significant and specific relation between patterns of discomfort overprediction (vs under- or accurate prediction) and negative self-reported health status and attitudes to exercise, lower levels of physical activity, as well as poorer scores for resting heart rate, cardiorespiratory fitness and body mass index (but not waist:hip ratio). Females were more likely to overpredict discomfort, were less active and had poorer physical health than males. The potential usefulness of the prediction match-mismatch paradigm for studying exercise-related appraisal processes as proximal determinants of physical activity are discussed. Information obtained from such studies could prove useful in public health education campaigns aimed at increasing levels of physical activity in the general population, particularly among the less active.     

Social Support in Cardiac Rehabilitation Exercise Maintenance: Associations with Self‐Efficacy and Health‐Related Quality of Life1

This study examined whether cardiac rehabilitation (CR) maintenance exercise participants who were high and moderate in social support (SS) differed in their types of self‐efficacy and health‐related quality of life, and whether SS was related to self‐efficacy. Measures of SS, self‐efficacy (i.e., walking, scheduling, in‐class efficacy), and health‐related quality of life (HRQL) were administered to 64 CR maintenance exercise participants. A one‐way, between‐groups MANOVA was significant (p < .01), indicating that CR participants higher in SS reported significantly greater self‐efficacy and physical HRQL than did their moderate counterparts. In addition, social support predicted significant variance in task self‐efficacy. The findings suggest that differential perceptions of SS are related to differences in walking, in‐class and scheduling self‐efficacy, and the physical component of HRQL among CR exercise maintainers.     

Age, exercise, and coding performance

We investigated the effects of exercise on the coding performance of young and older subjects. Hypotheses were tested that exercise either facilitates spatial localization or reduces susceptibility to distraction in older subjects. In a balanced design, we administered Digit Symbol and Symbol Digit coding tasks to exercisers and nonexercisers at two age levels under conditions of low or high within-task interference. The findings showed higher performance by the exercisers than by the nonexercisers only at the older age level and only with the Symbol Digit task. These findings support the hypothesis that exercise compensates for a loss of spatial localization skills with age. We found no evidence that susceptibility to distraction either increased with age or was affected by chronic exercise.     

Optimism, abstinence self-efficacy, and self-mastery: a comparative analysis of cognitive resources

The relationship between optimism, abstinence self-efficacy, and self-mastery was examined by investigating levels of these cognitive resources among two samples of recovering substance abusers: Oxford House residents who attended twelve-step groups and twelve-step members who had never lived in an Oxford House. Participants 'levels of optimism were significantly and positively related to both abstinence self-efficacy and self-mastery scores, as abstinence self-efficacy was significantly and positively related to participants' number of days abstinent. Participants who reported having more than 180 days abstinent reported significantly higher levels of abstinence self-efficacy than participants who reported having less than 180 days abstinent. In addition, among participants who reported having less than 180 days abstinent, Oxford House residents reported significantly higher levels of abstinence self-efficacy than twelve-step members. Overall, findings suggest that cognitive resources facilitate substance abusers' recovery and that the Oxford House model might provide high levels of support in their ongoing abstinence.     

Outcome Expectancies and Expectancy Accessibility in Exercise Behavior

Most people do not engage in recommended levels of physical activity. Social cognition research indicates that self‐reported outcome expectancies (OEs) are associated with exercise behavior, but self‐report assessments have limitations. We investigated whether reaction times (RTs) to endorse outcome expectancies would capture unique information about spontaneous cognitive processes associated with exercise behavior. Exercisers and sedentary participants were randomly assigned to complete an exercise test or to rest. Participants completed an OE questionnaire and RT task before and after the test/rest. On the RT task, exercisers endorsed exercise positive outcomes more rapidly than sedentary participants. Furthermore, reported OEs and RTs were independently associated with exercise status. RTs may afford a more comprehensive assessment of the cognitive processes associated with exercise behavior.     

Somatic response to stress, physical symptoms and health service use: The role of current stress

The study examined physical symptoms and health service utilization of subjects high or low on a measure of the tendency to experience stress somatically and high or low on a measure of current stress. High somatic responders reported greater numbers of symptoms than low somatic responders regardless of stress level. However, high somatic responders who were experiencing high levels of current stress reported significantly more symptoms than high somatic responders who were experiencing low levels of stress. These findings indicate that somatic response to stress reflects both a general tendency to focus on physical symptoms, and a specific tendency to focus more on physical symptoms when under stress. Analysis of health service records indicated that high somatic responders had more visits prompted by symptoms than low somatic responders, but did not differ in frequency of health service visits designed to maintain health. The findings further clarify the relationship between somatic response to stress, physical symptoms and health service use.     

Relationships between physical exercise and cognitive abilities in older adults

We investigated relationships between physical exercise and the cognitive abilities of older adults. We hypothesized that the performance of vigorous exercisers would be superior to that of sedentary individuals on measures of reasoning, working memory, and reaction time. We gave a series of cognitive tasks to 62 older men and women who exercised vigorously and 62 sedentary men and women. Multivariate and univariate analyses of variance, with age and education as covariates, indicated that the performance of the exercisers was significantly better on measures of reasoning, working memory, and reaction time. Between-group differences persisted when vocabulary, on which the performance of exercisers was superior, was used as a third covariate. Subsequent analyses showed that neither self-rated health, medical conditions, nor medications contributed to the differences between exercise groups. Results suggest that the possible contribution of physical exercise to individual differences in cognition among older adults should be further investigated.     

Imagery Use and Self‐Determined Motivations in a Community Sample of Exercisers and Non‐Exercisers1

This study examined the patterns of imagery use and motivational self‐determination, and the relationships between them in regular exercisers (RE), non‐exercisers who intend to exercise (NE‐I), and non‐exercisers who do not intend to exercise (NE‐N). A survey was conducted through the random sampling of a large population. The NE‐N group reported using the same amount of imagery as the other 2 groups. NE‐N participants were the least and RE participants the most self‐determined, with NE‐I participants in between. The patterns of association among imagery and self‐determination were different for the NE‐N participants than the other 2 groups. It was concluded that imagery interventions that might be successful with RE and NE‐I participants are unlikely to be effective with NE‐N participants.     

Prospective and Daily Measures of Acute Thoughts, Decisional Struggle, and Coping: Measurement Correspondence and the Prediction of Exercise in Young Adults

Information on the daily stability–variability of decision-making social cognitions has not been obtained. Two purposes were: (1) to examine the correspondence between 1-week prospective and daily measures of acute exercise thoughts, decisional struggle, coping frequency, and coping self-efficacy and (2) prediction of moderate exercise. Seventy-seven experienced exercisers ( M age=22.36 years) completed a 1-week prospective and daily measures of social cognitions. Prospective and aggregated daily acute thoughts were the only non-correspondent measures. Aggregated daily acute thoughts were the only significant predictor of exercise (ß_standardized=.78, p <.01). Daily acute thoughts may be a determinant of moderate exercise in experienced exercisers due to the unpredictable nature of daily events, warranting attention to making daily exercise decisions.     

Exercise type relates to inhibitory and error processing functions in older adults

ABSTRACT

This study investigated the association between exercise type and inhibition of prepotent responses and error detection. Totally, 75 adults (M = 68.88 years) were classified into one of three exercise groups: those who were regular participants in open- or closed-skill forms of exercise, and those who exercised only irregularly. The participants completed a Stroop and task-switching tasks with event-related brain potentials (ERPs) recorded. The results revealed that regular exercisers displayed faster reaction times (RTs) in the Stroop task compared with irregular exercisers. The open-skill exercisers exhibited smaller N200 and larger P300a amplitudes in the Stroop task compared with irregular exercisers. Furthermore, the open-skill exercisers showed a tendency of shorter error-related negativity latencies at the task-witching test. The findings suggest that older adults may gain extra cognitive benefits in areas such as inhibition functioning and error processing from participating in open-skill forms of physical exercises.     

Extraversion and exercise addiction

Extraversion has been suggested as a factor associated with addiction. This claim was tested in relation to exercise addiction. Twelve exercise addicts were compared with 12 nonaddicted individuals who were committed to regular exercise and with 12 nonexercising individuals drawn from the same student population. Addicted exercisers did not differ from nonaddicted exercisers in extraversion, although exercisers as a group were more extraverted than nonexercisers. The results are interpreted as evidence against the claim that extraversion is a component of the addictive personality profile.     

Self-Presentation in Exercise Contexts: Differences Between High and Low Frequency Exercisers

The present study investigated the relationship between cognitive manifestations of self-presentation (social physique anxiety, self-presentational efficacy, impression motivation, and exercise imagery) and exercise behavior in 235 female exercisers. Each participant completed the Social Physique Anxiety Scale, a measure of self-presentational efficacy, the impression motivation subscale of the Self-Presentation in Exercise Questionnaire, and the Exercise Imagery Questionnaire. The results of a MANCOVA indicated high-frequency exercisers reported higher levels of efficacy expectancy, outcome value, and exercise imagery than did low-frequency exercisers. Semi-partial correlations showed efficacy expectancy, outcome expectancy, and appearance imagery each accounted for significant variance in social physique anxiety, independent of other predictors. Self-presentational efficacy expectancy appears to be a potent variable in both exercise behavior and social physique anxiety.     

Moderate Aerobic Exercise, T'ai Chi, and Social Problem-Solving Ability in Relation to Psychological Stress

This study evaluated the importance of exercise mode, social problem-solving ability, gender, and age in relation to anxiety and perceived daily hassles. Adult participants were classified as moderate aerobic exercisers, T'ai Chi exercisers, or sedentary via completion of a questionnaire. Social problem-solving ability, state and trait anxiety, and frequency and severity of daily hassles were measured. As predicted, scores indicating effective social problem-solving ability were associated with fewer reported severe daily hassles and with lower scores on state and trait anxiety. For state and trait anxiety, a main effect of exercise mode emerged after age and gender were controlled. A 3-way interaction involving age, gender, and exercise mode suggested that age and gender moderate the effects of exercise on anxiety, that is, the stress-reducing efficacy of different exercise modes may be dependent on a person's age and/or gender. Implications for theory, research, and practice are discussed.     

The interactive effect of personality, time of day, and caffeine: a test of the arousal model

The personality dimension of introversion/extraversion is one of the few personality dimensions that can be reliably identified from study to study and investigator to investigator. The importance of this demension within personality theory is due both to the stability of the trait and the influential theory of H. J. Eysenck. The basic assumption in Eysenck's theory of introversion/extraversion is that the personality differences between introverts and extraverts reflect some basic difference in the resting level of cortical arousal or activation. Assuming that there is a curvilinear relationship (an inverted U) between levels of stress and performance leads to a test of this arousal theory. That is, moderate increases in stress should hinder the performance of introverts who are presumably already highly aroused. However, the same moderate increase in stress might help the performance of the presumably underaroused extraverts. Revelle, Amaral, and Turriff reported that the administration of moderate doses of caffeine hindered the performance of introverts and helped the performance of extraverts on a cognitive task similar to the verbal test of the Graduate Record Examination. Assuming that caffeine increases arousal, this interaction between introversion/extraversion and drug condition supports Eysenck's theory. This interaction was explored in a series of experiments designed to replicate, extend, and test the generality of the original finding. The interaction between personality and drug condition was replicated and extended to additional cognitive performance tasks. However, these interactions were affected by time of day and stage of practice, and the subscales of introversion/extraversion, impulsivity, and sociability, were differentially affected. In the morning of the first day, low impulsives were hindered and high impulsives helped by caffeine. This pattern reversed in the evening of the first day, and it reversed again in the evening of Day 2. We concluded that the results from the first day of testing require a revision of Eysenck's theory. Instead of a stable difference in arousal between low and high impulsives, it appeared that these groups differed in the phase of their diurnal arousal rhythms. The result is that low impulsives are more aroused in the morning and less aroused in the evening than are the high impulsives. A variety of peripheral or strategic explanations (differences in caffeine consumption, guessing strategies, distraction, etc.) for the observed performance increments and decrements were proposed and tentatively rejected. It seems probable that some fundamental change in the efficiency with which information is processes is responsible for these performance changes.     

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.     

Perceived self-regulation of exercise goals and interfering goals among regular and irregular exercisers: a life space analysis

ObjectivesTo investigate whether adults self-classified as regular and irregular exercisers tend to differentially perceive the self-regulation of their exercise goals (a between groups comparison) and whether the groups’ differ in their self-regulatory perceptions of an exercise goal versus a goal that strongly interferes with exercise (a within groups comparison).DesignsCross-Sectional Survey.MethodsCollege students (N=399, 66% female), who were either regular or irregular exercisers, completed the Goal Systems Assessment Battery [GSAB; Karoly, P., & Ruehlman, L. S. (1995). Goal cognition and its clinical implications: Development and preliminary validation of four motivational assessment instruments. Assessment, 2, 113–129] for the goal of exercise and for a self-selected interfering goal. The GSAB gauges how individuals evaluate multiple functional components of self-regulation.ResultsA doubly multivariate MANOVA revealed a significant interaction between exercise regularity and goal type. Irregular exercisers manifested a pattern of goal regulatory thinking favoring their interfering goal relative to their exercise goal with respect to its value and the extent of their monitoring, planning, social comparison, and self-rewarding their progress toward that goal. Regular exercisers tended not to make such regulatory distinctions.ConclusionsAlthough life pursuits identified as interfering with exercise (e.g. academic goals) generally require more of a psychological investment than engaging in exercise, regular exercisers tend to construe their physical activity goals in a manner that closely matches their ratings of competing life aspirations. A dual focus on exercise goals and their aspirational rivals may inform motivational theory and intervention.
