Effects of endurance training on body-consciousness in women

Translation, Cross-Cultural Adaptation, and Psychometric Validation of the English Version of the Postural Awareness Scale

PURPOSE

The Postural Awareness Scale (PAS) was developed among a sample of German speakers to measure self-reported awareness of body posture. The first aim of this study was to conduct an English translation and cross-cultural adaptation of the PAS. The second aim was to assess psychometric properties of the English version of the PAS.

METHODS

Forward and backward translations were conducted. The translated scale was then pretested in a small sample of English-speaking adults (n = 30), followed by cognitive interviews. Finally, consensus of the translated scale was achieved among an expert committee (n = 5), resulting in the Postural Awareness Scale-English Version (PAS-E). Psychometric properties of the PAS-E were investigated among a sample of individuals with chronic pain (n = 301) by evaluating factor structure, reliability, and construct validity. Analyses of variance were conducted to calculate differences in PAS-E scores between specific subgroups (pain conditions, sex, and history of mindfulness practice). Linear regression analyses investigated whether the scores on the PAS-E predicted levels of pain, stress, and mood.

RESULTS

The results obtained from an exploratory factor analysis showed a two-factor solution and were supported by a confirmatory factor analysis. The scale demonstrated good internal consistency and satisfactory construct validity. No significant differences related to sex at birth or pain duration were found.

CONCLUSION

PAS-E demonstrated good psychometric properties, and therefore, can and should be used both for research and clinical practice.

Mind and Body: Italian Validation of the Postural Awareness Scale

Postural awareness (PA) refers to a subjective conscious awareness of body posture and falls within the framework of mind-body integration. The aim of this research was to validate and evaluate psychometric properties of the Postural Awareness Scale (PAS) in an Italian population sample (n = 928; 45.04% men and 54.96% women; mean age = 29.96 years, standard deviation = 11.44). The results obtained with Velicer's Minimum Average Partial Test, Horn's Parallel Analysis, and exploratory factor analysis showed a two-factor solution, as supported by the confirmatory factor analysis: ease/familiarity with postural awareness and need for attention regulation with postural awareness. Furthermore, the findings highlighted both a good internal consistency (α = 0.76 for the total scale and α = 0.80, α = 0.79 for the two subscales) and a satisfactory construct validity. Furthermore, multivariate analysis of variance was carried out to assess differences in PA between specific subgroup. In particular, the positive effects of physical activity and healthy body weight were confirmed, whereas no significant differences related to gender or age were found. All these findings suggest that the Italian version of the PAS is a rapid instrument with good psychometric properties, which can be useful both for research and clinical practice.

Quality of life of female and male vegetarian and vegan endurance runners compared to omnivores - results from the NURMI study (step 2)

Background

Health-related effects of a vegetarian or vegan diet are known to support parameters positively affecting exercise performance in athletes, whereas knowledge about psyche and wellbeing is sparse. Therefore, the aim of the Nutrition and Running High Mileage (NURMI) Study (Step 2) was to compare Quality of Life (QOL) scores among endurance runners following a vegetarian or vegan diet against those who adhere to an omnivorous diet.

Methods

The study was conducted following a cross-sectional design. A total of 281 recreational runners (159 women, 122 men) completed the WHOQOL-BREF questionnaire consisting of the domains physical health, psychological wellbeing, social relationships and environment, which generates scores on a scale from 4 to 20. Data analysis was performed using ANOVA.

Results

It was found that 123 subjects followed an omnivorous diet and 158 adhered to a vegetarian/vegan diet. There were 173 runners who met the inclusion criteria (‘NURMI-Runners’), among them 103 half-marathoners and 70 marathoners and ultramarathoners, as well as 108 10 km runners as control group. Overall QOL scores were high (~ 16.62 ± 1.91). Men had higher scores than women due to high scores in the physical health and psychological well-being dimensions. Adhering to an omnivorous diet affected environment scores for women and social relationships scores for men. A minor effect concerning race distance was observed in women, where half-marathoners had a higher environmental score than 10-km runners. A moderate diet×race distance interaction on environment scores was shown for men.

Conclusions

The results revealed that endurance runners had a high QOL regardless of the race distance or diet choice. These findings support the notion that adhering to a vegetarian or vegan diet can be an appropriate and equal alternative to an omnivorous diet.

Measuring a new facet of post traumatic growth: Development of a scale of physical post traumatic growth in men with prostate cancer

PURPOSE

This study developed a measure of physical post traumatic growth (physical post traumatic growth inventory; P-PTGI) in men with prostate cancer.

METHODS

A pool of items was created from themes identified in a qualitative study. A quantitative study was then conducted to assess the psychometric properties of the P-PTGI in a sample of 693 prostate cancer survivors.

RESULTS

Tests of dimensionality revealed that the 20-item P-PTGI contained two factors: Health Autonomy and Health Awareness. Results demonstrated that scale score reliability for the P-PTGI and its subscales was excellent. In support of the scale's convergent validity, scores on the P-PTGI correlated positively with mindfulness and quality of life, and correlated negatively with depression and anxiety. A statistically significant correlation between the P-PTGI and another robust indicator of post traumatic growth attests to its concurrent validity.

CONCLUSIONS

While further investigation of the P-PTGI's psychometric properties is required, preliminary findings are promising.

Relations of Body Concerns and Exercise Behavior: A Meta-Analysis

Numerous studies have examined the relations between body concerns and exercise. This meta-analysis is based on 35 studies with exercise programs influencing body concerns. There was an overall effect of .45, suggesting that exercise positively affects body concerns. Moderator variables, such as sex, type of exercise, and length of intervention were examined and discussed. Generally, there were no sex differences in effects of exercise on body concerns, but anaerobic exercise such as weight training generated a stronger effect ( d=.64) than aerobic-type exercises such as jogging ( d=.40).

Body awareness: construct and self-report measures

Objectives

Heightened body awareness can be adaptive and maladaptive. Improving body awareness has been suggested as an approach for treating patients with conditions such as chronic pain, obesity and post-traumatic stress disorder. We assessed the psychometric quality of selected self-report measures and examined their items for underlying definitions of the construct.

Data sources

PubMed, PsychINFO, HaPI, Embase, Digital Dissertations Database.

Review methods

Abstracts were screened; potentially relevant instruments were obtained and systematically reviewed. Instruments were excluded if they exclusively measured anxiety, covered emotions without related physical sensations, used observer ratings only, or were unobtainable. We restricted our study to the proprioceptive and interoceptive channels of body awareness. The psychometric properties of each scale were rated using a structured evaluation according to the method of McDowell. Following a working definition of the multi-dimensional construct, an inter-disciplinary team systematically examined the items of existing body awareness instruments, identified the dimensions queried and used an iterative qualitative process to refine the dimensions of the construct.

Results

From 1,825 abstracts, 39 instruments were screened. 12 were included for psychometric evaluation. Only two were rated as high standard for reliability, four for validity. Four domains of body awareness with 11 sub-domains emerged. Neither a single nor a compilation of several instruments covered all dimensions. Key domains that might potentially differentiate adaptive and maladaptive aspects of body awareness were missing in the reviewed instruments.

Conclusion

Existing self-report instruments do not address important domains of the construct of body awareness, are unable to discern between adaptive and maladaptive aspects of body awareness, or exhibit other psychometric limitations. Restricting the construct to its proprio- and interoceptive channels, we explore the current understanding of the multi-dimensional construct and suggest next steps for further research.

The influence of appearance, health, and future orientations on tanning behavior

OBJECTIVE

To compare the influence of appearance, health, and future orientations on tanning attitudes and behaviors.

METHODS

The study was an online survey of 406 volunteers from a university community.

RESULTS

Appearance and future orientations were more closely related to ultraviolet radiation exposure and protection than was health orientation.

CONCLUSIONS

Future research and interventions may benefit from closer attention to associations between specific motivational orientations and behaviors.

Comments on "the Feldenkrais Method: a dynamic approach to changing motor behavior"

The Feldenkrais Method has recently been discussed to fit within a dynamic systems model of human movement. One basis for this discussion is that small changes in one system--for example, enhanced body awareness--has far reaching implications across the whole of human performance. An alternative view on the Feldenkrais Method is argued here. It is argued that the clinical data do not support the Feldenkrais Method as being an effective way to improve motor performance. Further, it is argued that positive outcomes in pain and other wellness measures following Feldenkrais interventions can be ascribed to self-regulation. As part of this discussion, the role of body awareness, attentional focus, and kinesthesia in motor leaning and control are explored.

Effects of a circuit weight training program on the body images of college students

OBJECTIVE

The present investigation examined the extent to which participation in a 6-week circuit-weight training program produced changes in participants' body images relative to a matched control group.

METHOD

The weight trainers consisted of 39 college students (27 women and 12 men). The control group of 39 individuals did not weight-train currently or within the past year. All participants were pre- and posttested on the Multidimensional Body Self-Relations Questionnaire, the Social Physique Anxiety Scale, and the Physical Self-Efficacy Scale. Weight trainers were also pre- and posttested on muscular strength and assessed on their motives for exercise.

RESULTS

The program successfully increased upper- and lower-body strength. In contrast to the comparison group, weight trainers had a significantly improved evaluation of their appearance, greater body satisfaction, reduced social physique anxiety, and enhanced physical self-efficacy. Outcomes were unrelated to the extent of concurrent aerobic exercise and largely unrelated to exercise motives.

DISCUSSION

Even a relatively brief weight training program can produce improvements in multiple aspects of body image. Further research should investigate weight training as an adjunct to psychosocial treatments of body dissatisfaction.

Analysis of body esteem in female college athletes and nonathletes

This research compared the scores on the three subscales of the Body Esteem Scale of 67 female intercollegiate athletes from various sports, and 57 female nonathlete college students enrolled in regular college classes. Analysis indicated no significant differences between the groups on the Sexual Attractiveness and Weight Concern subscales, but only on the Physical Condition subscale, with athletes reporting higher scores and more positive perceptions of body esteem than nonathletes.

Modifications of body-image induced by virtual reality

In contrast to the great number of publications on body image, only a few papers have focused on the treatment of a disturbed body image. In general, two direct and specific approaches are usually used, a cognitive/behavioural therapy to influence patient's feelings of dissatisfaction and a visuomotor therapy with the aim of influencing bodily awareness. The aim of this study was both to develop a virtual reality environment integrating the two approaches and to test its efficacy on a nonclinical sample of 24 women. Before and after a 10-min. virtual experience all the subjects made ratings on the Figure Rating Scale and the Contour Drawing Rating Scale. Analysis showed a significant reduction in body dissatisfaction without any major side effect.

A comparative evaluation of cognitive-behavioral therapy (CBT) versus exercise therapy (ET) for the treatment of body image disturbance. Preliminary findings

Cognitive-behavioral therapy (CBT) was compared to a combination of aerobic/anaerobic exercise therapy (ET) for the treatment of elevated levels of body image disturbance in college females. CBT consisted of a modification of the 1987 Butters and Cash procedure that was tailored for group intervention; ET consisted of weightlifting and aerobic dancing. Using a counterbalancing procedure, the same therapists conducted both 6-week interventions, which were compared to a nontreated control group. Results revealed equivalent reductions for both treatment groups when compared to controls on measures of body image disturbance reflective of trait and state body weight anxiety, cognitive-behavioral aspects of appearance, and overall body dissatisfaction. Unfortunately, few subjects were available for follow-up analyses, preventing an evaluation of the stability of changes. The findings are discussed with regard to the potential role of fitness training as an adjunct to cognitive-behavioral interventions for body image disturbance.

Body esteem and enrollment in classes with different levels of physical activity

Differences in self-reported scores on the Body Esteem Scale were recorded for college women and men who participated in classes requiring differing amounts of physical activity. Scores for 116 women and 38 men were compared to scores for 99 college women and 60 college men enrolled in classes requiring vigorous or little physical activity, respectively. The correlation between participation and body esteem was also examined. The Body Esteem Scale was given to the subjects during the first and last weeks of one semester. Multivariate analysis of variance of scores indicated significant differences initially among the two groups of women on three subscales, Sexual Attractiveness, Weight Control, and Physical Condition, while mean over-all scores for body esteem were higher for women in the vigorous activity group than in the comparison group. No significant differences were found at the later testing. For men, no significant differences were obtained at either testing.

Changes in body consciousness relate to regularity of exercise training

Previous work has indicated improvement for scores on self-reported measures of body consciousness as aerobic fitness increased. To test whether exercise sufficient to improve aerobic fitness must be sustained on a regular basis to achieve positive changes in body consciousness, two separate periods of exercise training of 2 or 3 weeks duration were completed by nine female volunteers. The two exercise sessions were separated by 10 days of no exercise. Five women, as controls, did not exercise. Despite significant physiological improvement in the exercisers, no changes in self-perceived body self-consciousness were observed. Such changes may depend on the maintenance of a regular exercise regimen or the magnitude of physiological improvement.

Physiological and psychological responses to exercise with an induced attentional focus

In this study techniques were employed to induce exercising subjects to focus attention on themselves or on an external event. A total of 20 adult subjects (10 men and 10 women) were familiarized with a treadmill exercise protocol and then on two subsequent occasions performed submaximal exercise followed by a run to exhaustion under attentional conditions of self-focus (watching themselves in a mirror while listening to their breathing) and external focus (watching and listening to a movie). The order of focus conditions was counterbalanced among subjects. Analysis of postexperimental responses from subjects indicated that the procedures used to induce each type of attentional focus were successful. However, physiological and psychological responses in the two focus conditions were not always uniform for men and women, particularly during light work when men tended to have higher heart rates and significantly lower Rated Perceived Exertion while women had lower heart rates and higher Rated Perceived Exertion under self-focused conditions than under externally focused conditions. Possible explanations for the incongruence of physiological and psychological responses of men and women to the two types of attentional focus are discussed.
