The purpose of this study was to examine the relationships among body mass index (BMI), body image perception, physical activity habits, and exercise stage of change in college-aged females. Volunteers (N = 134) completed a survey of demographics, Stage of Exercise Scale (SOES; Cardinal, 1995a; Cardinal, 1995b), Physical Activity History questionnaire (PAH; Jacobs, Hahn, Haskell, Pirie, & Sidney, 1989), and Body Shape Questionnaire (BSQ; Cooper, Taylor, Cooper, & Fairburn, 1987). Participants were categorized into five exercise stages of change: precontemplation, contemplation, preparation, action, and maintenance. Relationships between the variables were analyzed with Pearson r correlations. Kruskal-Wallis independence tests were also used for analyses. Approximately 60% of the participants reported current physical inactivity or irregular exercise. BMI and body image score were significantly linearly related, with higher body mass indicating more negative body image (r = 30, p <.017). Significant differences existed between exercise stages for physical activity score, X2 (3, N = 134) = 19.98, p <.05. Based upon follow-up tests participants in the maintenance stage had significantly higher physical activity scores than all other stages. No significant differences were found for BMI or body image between exercise stages. Regular exercisers had the highest frequency of disordered eating and weight-preoccupied attitudes and behaviors. The majority of these women were not currently regularly physically active, professed dissatisfaction with their current level of activity, and expressed a fear of being fat. Further study directed at specific factors related to body image and exercise behaviors, as well as the impact of stage-specific interventions are suggested.

In the United States, approximately one in three adults are classified as obese ( Flegal, Kruszon-Moran, Carroll, Fryar, & Ogden, 2016 ), defined as a body mass index (BMI) greater than 30 kg/m 2 . These numbers are even higher among women, with 40.4% of American women being classified as

Previous studies have demonstrated that parents may influence the physical activity (PA) levels of children. The present study sought to determine whether PA-related parenting behaviors were associated with the physical activity and relative weight of children, controlling for other covariates. A community sample of mothers (n = 193) of after-school-program attendees completed questionnaires assessing parental social support for PA, sedentary behavior, and moderate-to-vigorous physical activity. Children (N = 193, 51% girls) were objectively assessed for height and weight via stadiometer and digital scale, and the data were converted to body mass index (BMI) percentile via Centers for Disease Control and Prevention (CDC, 2010a) growth charts. Linear regression analysis revealed that maternal encouragement for child PA was positively related to both child PA and BMI percentile. However, mother-child shared physical activity was negatively related to child BMI percentile. Therefore, varying types of PA-related parenting behaviors may have differential relationships with child PA and relative weight.

This study has two purposes: (1) to observe the step-count patterns of adult women who participated in an eight-month healthy lifestyle-based book club intervention and (2) to describe step-count patterns across seasons and body mass index (BMI) categories. Sixty-two participants (mean age ± SD = 53 ± 9, 92% Caucasians) had complete pedometer data, which was used for data analysis. After weekly, hour-long, discussion-based meetings during months one through four, and bi-monthly meetings during months five through eight, women increased their step counts by 26%. Significant step-count differences were observed among seasons (p < .05), and from pre- to post-intervention (p < .05), with the lowest steps being reported in the fall and the highest in the spring. Women in the obese category continued to increase steps during the winter, while the healthy-weight group decreased steps. There was a significant correlation between the average steps taken during the intervention and changes in BMI from pre- to post-intervention (r = −.26, p < .05). Overall, positive step-count pattern observations were found among adult women participating in a healthy lifestyle-based intervention.

This study is an examintion of the effects of race and income on leisure-time physical activity among women (n = 116). Perceived benefits of and barriers to participating in leisure-time physical activity were also compared. A regression model utilizing social cognitive variables was used to explore factors which may predict physical activity participation. No significant differences emerged between the groups regarding the amount of physical activity they reported either by race or socioeconomic status. Time expenditure emerged significantly different by race (p < .001) and income (p < .000); middle-income women reported time as a barrier more than lower-income women and Whites were likelier to report time as a barrier more than Blacks. Middle-income women perceived greater (p < .01) physical performance benefits from exercise than lower-income women. Social interaction, time expenditure, and body mass index were the strongest predictors of physical activity. The data and findings could be useful for increaseing our understanding of economic and racial disparities in physical activity participation and garnish information for use in constructing interven programs.

The main purpose of this article is to review a series of studies (N = 18) on the physical characteristics, physiological attributes, throwing velocity and accuracy, and on-court performances of female team handball players. Studies were selected from a computerized search in electronic databases (PubMed, SPORT Discus) as well as from a manual search. Five main findings emerged from this review: (1) a tall and heavy build was advantageous in team handball—mean height ranged from 165.9±.3 cm to 179±4 cm and mean body mass ranged from 62.4±6.2 kg to 72.0±6.3 kg; (2) VO2max values of female players were between 47-54 ml·kg-1·min-1; (3) throwing velocity was higher by as much as 11% in elite female players compared to amateur female players; (4) during 90% of playing time, heart rate (HR) was above 85% of HRmax, and the average VO2 was 79% of VO2max in female players; and (5) on-court distance covered averaged approximately 4 km and varied between 2-5 km in female players, depending on the playing position of the player. Most of the studies reviewed were cross-sectional, and only a few reported data on on-court performance. There is a need for additional manipulative studies to determine the influence of various training programs on game performance. In addition, conditioning programs that develop power and strength should be emphasized, and attention should be given to the player’s playing position and skill level.

Social physique anxiety (SPA) is a subtype of social anxiety that stems from self-presentational concerns about the appearance of one’s physique. The purpose of the present study was to examine correlates of SPA among individuals who instruct in a high social evaluation setting. Data from 286 female aerobic instructors (M age = 34.11) were collected on SPA, age, body mass index (BMI), exposure to the exercise setting (number of years spent instructing and participating in aerobic classes), and motive for instructing (leadership, affect enhancement, self-presentational). Hierarchical multiple regression analyses revealed that BMI, age, and motive for instructing accounted for 25% of the variance in SPAS scores, F(6, 223) = 12.11, p < .0001. Women who instructed for self-presentational motives had significantly higher SPA compared to women who instructed for leadership and affect enhancement motives. Contrary to hypothesis, the amount of exposure to the aerobic exercise setting was unrelated to SPA. Based on this result, we suggest that repeated exposure to a physique salient environment does not diminish women’s self-presentational concerns about their bodies.
