There are an abundant number of published studies in which the authors state that post-pubertal men are stronger, faster and more powerful and therefore more proficient than women in many motor skills. The topics of strength and neuromuscular response time are phenomena that have been used in the past as bases for the rationalization that women do not have the physical characteristics that are essential requirements for front-line work as soldiers, firepersons, police officers and construction workers, and also that they are not as proficient as men in other occupations. This paper is a review of physiological and performance data that have contributed to our knowledge base in the areas of strength and neuromuscular response times of women. In addition, data regarding the deterioration of these parameters that occur with aging and the potential determent of this deterioration as a consequence of a lifetime of activity will be considered. Finally, a suggestion will be made that female and male data should be analyzed and reported in ways that eliminate genetic characteristics which bias the data.

Little is known about adolescent girls’ accuracy of perception of physical activity (PA) opportunities in their neighborhood. Furthermore, few studies have explored whether proximity to PA opportunities is associated with girls’ recent use. Participants included 356 high school girls enrolled in New Moves, a school-based physical activity intervention. Objective proximity to neighborhood PA opportunities was assessed using Geographic Information System (GIS) software. Girls self-reported their perceived proximity to resources and recent use of these opportunities. Girls’ perceived proximity of distance to a park, walking/biking trail, and recreational center was associated with recent use of these resources (P = .02, P < .001, P < .001, respectively), whereas associations were not found with objective measures of distance. Both perceived and objective proximity were associated with recent use of a private fitness facility (P = .006 and P = .002, respectively). Perceived proximity to neighborhood PA opportunities is associated with use of those resources among adolescent girls. Increasing awareness of neighborhood opportunities could be a viable method to increasing PA.

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 Canada, as in other neo-liberal states, a physically active lifestyle is discursively constructed as a moral activity, whereas a sedentary lifestyle is criticized as a failure to take charge of one’s health (Bercovitz, 2000; Lupton, 1997). This study aims to understand how Canadian men and women articulate the discursive connections between physical activity and health risks and how those connections are reflected in their reported behaviors. Analysis shows that some of the 37 men and 36 women interviewed not only “talk the talk” regarding physical activity, they also claim to lead an active lifestyle. However, “active” participants were disciplined into frequent physical activity not simply by the discursive effects of the fitness mantra promising better health, but because they enjoyed it. Conversely, the not-active-enough participants were unwilling to fully comply with the requirements of the fitness discourses because they found no pleasure in “exercise.” Despite adopting physical activity as a key strategy to manage their health risks, interviews revealed that the latter group were not docile bodies (Foucault, 1995).

The purpose of this prospective study, which is part of the Finnish Evergreen project, was to study depressive symptoms and positive self-esteem in different physical activity categories among men and women aged 65 and over during an eight-year period. Only subjects (N=663) who participated in both the baseline (1988) and the follow-up (1996) interviews were selected for the analyses. Depressive symptoms and positive self-esteem were assessed using a modified version of Beck’s 13-item scale (RBDI; Raitasalo, 1995). The intensity of physical activity was assessed on a seven-point scale ranging from the performance of necessary chores only to competitive sports. In addition, lifelong physical exercise was assessed by two questions. Number of chronic diseases and marital status were obtained from the participants themselves. Gender, lifelong physical exercise, intensity of physical activity and chronic diseases were associated with depressive symptoms and self-esteem. Physically active men and women and lifelong exercisers reported fewer depressive symptoms than their sedentary counterparts both at baseline and follow-up. The self-esteem scores were fairly similar among both sexes in the different categories of physical activity in both study years. The most active women had higher self-esteem scores than the more sedentary ones. Based upon these results, physical activity and lifelong physical exercise may prevent depressive symptoms and maintain positive self-esteem in older age. Positive measures should therefore be taken to support regular physical activity among older men and women.

The purpose of the study was to investigate how involvement in exercise and participation in team sports were related to the multidimension self-perceptions of middle school females. The study was conducted in 2 middle schools with 181 8th-grade females. Instruments used were the Physical Activity Survey and Harter’s Self-Perception Profile for Children. Results show that participation in team sports was related to four domains of self-perception: social acceptance, athletic competence, scholastic competence, and global self-worth. Informal exercise was related to social acceptance and global self-worth of middle school females. Therefore, it appears that both team sports and exercise may be important in enhancing self-concept in middle school females. Results also show that over half of middle school females in this study participated in three or more team sports during middle school. However, almost half of these students report exercising informally less than three times a week. These results support the increased opportunities of team sports for middle school females.

Athletes are at a high risk for eating disorders due to the pressures placed on them by themselves as well as coaches. The purposes of this study were (1) to determine the knowledge level of eating disorders among cross country coaches, (2) to determine their level of confidence in this knowledge, and (3) to determine reported sources of educational resources. Four schools were randomly selected from each NCAA Division I conference (return rate: 48%). A two-part questionnaire assessed sources of information and knowledge of eating disorders. Literature and sponsored programs were the two most common sources of information. For the 30 knowledge questions, coaches indicated their confidence level on a 4-item Likert-type scale. The knowledge of the majority of coaches was relatively high, and those with higher accuracy also had higher confidence. The confidence level and the percent of coaches answering each question correctly were significantly correlated, r=0.56 (p<0.01) but the confidence level and the percent answering incorrectly were not significantly correlated, r=0.24 (p=0.24). There were no significant differences in knowledge scores considering years of coaching (p=0.67) nor were there any significant differences in the scores between males and females (p=0.17). Although the cross country coaches were quite knowledgeable, additional ways to increase knowledge of eating disorders are needed.

This study examined possible determinants of some of the health behaviors of larger women. Specifically, it was of interest to discern if affect (depression, social physique anxiety) mediated the relationship between self-conceptions (global self-worth, perceived physical appearance) and behavior (disordered eating, physical activity). The investigation was grounded in the model of self-worth forwarded by Harter (1987). A total of 71 overweight or obese women agreed to participate in the study. Data collection involved a researcher meeting individually with each of the participants to record physical assessments as well as responses to a packet of self-report questionnaires. A series of canonical correlation analyses were then conducted to test each of the three conditions for mediation effects outlined by Baron and Kenny (1986). Results suggested that indeed the set of self-conceptions indirectly influenced the set of behaviors via the set of affect variables. Surprisingly, however, involvement in physical activity failed to contribute to the multivariate relationships. The findings further our understanding of how self-conceptions are related to behavior and highlight the value of examining multiple health behaviors in parallel.
Physical inactivity, overweight, and obesity are endemic in the United States and in the developed world, leading to increased morbidity and mortality. More information is needed regarding the physical activity beliefs, attitudes, barriers, and perceived self-control among those who are sedentary and weight-challenged. The purpose of this study was to elicit physical activity beliefs about feasibility, pleasure, and movement descriptions from sedentary, middle-aged, overweight women.
Open-ended questions were used throughout individual interviews with 23 participants (age: M = 52.0, SD = 7.3; BMI: M = 34.2, SD = 9.79); attitudes and beliefs regarding physical activity and movement descriptions were documented. Participants were divided into those who were completely sedentary (12 women) and those who regularly engaged in physical activity (11 women).
A content analysis revealed that sedentary women were less active and had more perceived barriers to physical activity than active women. The most frequently cited perceived barriers were injuries, caregiving responsibilities, time, age, dislike of sweating, and depression. Sedentary women were less likely to report physical activity as pleasurable; they were also more likely to cite having an exercise buddy as an optimal activity situation. The most frequently cited pleasurable activities in both groups were yoga, movement to music, stretching, and walking.
This study provided evidence that perceived barriers to physical activity must be addressed, that low-intensity programs are needed and desired by overweight and sedentary women, and that movement activities must be found that are enjoyable for the target population.

Dancers, like other athletes and performers, are faced with the pressure to obtain a particular body shape and size that stems from varied etiological factors (e.g., personality characteristics, demands of the dance environment) (Robson, 2002). This study examined specific concerns for college dancers by utilizing quantitative and qualitative forms of inquiry. The purpose of the initial phase was to assess weight-related pressures, social physique anxiety, and disordered eating in college female modern dancers (N=107) using the Weight Pressure in Dance (Reel & Gill, 1996), Social Physique Anxiety Scale (Hart, Leary, & Rejeski, 1989), and The Eating Disorder Inventory (Garner, 1991). An overwhelming majority (76%) of the dancers reported pressures to lose weight with the most commonly cited stressor being the mirror followed by costumes, performance advantage, comparison to other dancers, and landing the best roles. The mean social physique anxiety score was moderate, but 35 dancers exhibited a high degree of social physique anxiety. In addition, the dancers had a lower tendency toward disordered eating compared to college females (Garner, 1991). The second phase of the study confirmed that modern dancers experience unique pressures. Through qualitative inquiry, the participants’ individualized experiences related to body image and the culture of modern dance could be shared.
