To determine sex and race differences in muscle power per unit of muscle contraction, knee-extensor muscle power normalized for knee-extensor muscle volume was measured in 79 middle-aged and older adults (30 men and 49 women, age range 50–85 years). Results revealed that women displayed a 38% faster peak movement velocity than men and African Americans had a 14% lower peak movement velocity than Whites of a similar age when expressed per unit of involved muscle (p < .001). As expected, men exhibited greater knee-extensor strength and peak power per unit of muscle than women, but women had a faster knee-extension movement velocity per unit of muscle than men at the same relative strength level. Moreover, African Americans had greater knee-extensor muscle volume than Whites but exhibited lower knee-extensor strength and lower movement velocity per unit of muscle when tested at the same relative strength levels.

A 50-item questionnaire measuring athletes’ attitudes toward seeking a sport psychology consultant (ATSSPCQ) was initially developed and then administered to 48 African American and 177 Caucasian student-athletes at a NCAA Division I university. Principal components factor analyses were conducted to extract initial factors and then varimax orthogonal rotation was performed. The analyses produced three dimensions of athlete attitude that accounted for 35% of the variance: stigma tolerance, confidence in a SPC/recognition of need, and interpersonal openness/willingness to try a SPC. A MANOVA and follow-up discriminant function analyses were then performed to identify the factors that maximized differences between gender and race. Significant differences in stigma tolerance were found for both gender and race. SPCs were stigmatized more by male athletes than by female athletes and more by African American athletes than by Caucasian athletes. No other significant effects were obtained.

The purpose of this study was to identify racial differences in physical activity (PA), fitness, and BMI in female 8th-grade sports participants and nonparticipants. Girls from 31 South Carolina middle schools (N = 1,903, 48% White; mean age = 13.6 ± 0.63) reported PA and previous year sports-team participation, completed a submaximal fitness test, and had height and weight measured. Sports team participation was positively associated with PA and negatively associated with television viewing and BMI, in a dose-response manner. Compared with Whites, African-Americans reported less PA and more television viewing, and had greater BMI scores. Whereas PA intervention programs that incorporate a sports-team component could benefit all girls, African-American girls could be specifically targeted because of their lower physical activity.

In drawing from Herek’s (2007, 2009) sexual stigma and prejudice theory, the purpose of this study was to examine the relationship among prejudice toward sexual minority coaches, religious fundamentalism, sexism, and sexual prejudice and to determine whether race affected these relationships. The authors collected data from 238 parents. Results indicated that Asians expressed greater sexual prejudice than Latinos and Whites, while African Americans expressed more religious fundamentalism than did Whites. There were also differences in the associations among the variables. For African Americans, sexism held the strongest association with prejudice toward sexual minority coaches. While for Asians and Whites, religious fundamentalism held the strongest association, contact with lesbian and gay friends was a significant predictor of prejudice for Asians, but not for the other groups. For Latinos, both religious fundamentalism and sexism were associated with sexual prejudice. The authors discuss the results in terms of theoretical and practical implications.

Purposes of this study included the identification of physical activity (PA) levels, and the types of activity, as well as the determination of racial differences in these factors between African-American (AA) (n=626) and White (WH) (n=226) adolescent females.
PA was measured using a one week recall. Approximately 1/2 of WH and 1/3 of AA female adolescents were sufficiently physically active (Blair, 1992) to produce health benefits. Less than twenty-five percent of study participants met a newly established guideline addressing moderate to vigorous PA (Sallis & Patrick, 1994). Younger adolescents were more active than older adolescents.
Accounting for differences in age and socioeconomic status WH females were more active than AA females. African-American and WH females participated in similar types of activity. Walking was the most frequently cited mode of activity.

Influences on TV viewing time, which is associated with adverse health outcomes such as obesity and diabetes, need clarification. We assessed the relation of neighborhood socioeconomic status (SES) and walkability with TV viewing time in the Black Women’s Health Study, a prospective study of African American women.
We created neighborhood SES and walkability scores using data from the U.S. census and other sources. We estimated odds ratios for TV viewing 5+ hours/day compared with 0–1 hours/day for quintiles of neighborhood SES and walkability scores.
Neighborhood SES was inversely associated with TV viewing time. The odds ratio for watching 5+ hours/day in the highest compared with the lowest quintile of neighborhood SES was 0.66 (95% CI 0.54–0.81). Neighborhood walkability was not associated with TV viewing time.
Neighborhood SES should be considered in devising strategies to combat the high levels of sedentariness prevalent in African American women.

Using intersectionality and hegemony theory, we critically analyze mainstream print news media’s response to Don Imus’ exchange on the 2007 NCAA women’s basketball championship game. Content and textual analysis reveals the following media frames: “invisibility and silence”; “controlling images versus women’s self-definitions”; and, “outside the frame: social issues in sport and society.” The paper situates these media frames within a broader societal context wherein 1) women’s sports are silenced, trivialized and sexualized, 2) media representations of African-American women in the U. S. have historically reproduced racism and sexism, and 3) race and class relations differentially shape dominant understandings of African-American women’s participation in sport. We conclude that news media reproduced monolithic understandings of social inequality, which lacked insight into the intersecting nature of oppression for women, both in sport and in the United States.

The research sought to find the salient perceived characteristics of playgrounds for African-American children and their parents, and to test effects of changes in those characteristics on playground choice.
Thirty-one African-American children and their parents sorted 15 photographs of playgrounds for similarity. Nonmetric multidimensional scaling on the similarity scores and correlations between the resulting dimensions and judged characteristics of each playground revealed salient perceived characteristics. Study 2 had 40 African-American children and their parents view pairs of photographs, manipulated on the salient characteristics, and pick the one to play on (child question) or for the child to play on (parent question). A third study inventoried and observed children’s activities in 14 playgrounds.
Study 1 found seats, fence, playground type, and softness of surface as salient perceived characteristics of the playground. Study 2 found that participants were more likely to pick playgrounds with equipment and playgrounds with a softer surface. Study 3 found higher levels of physical activity for playground settings with equipment.
The findings confirm correlational findings on the desirability of equipment and safety. Communities need to test the effects of changes in playgrounds.

Few studies have compared physical activity (PA) and sedentary activity (SA) by grade and ethnicity, specifically including elementary school students. A cross-sectional probability-based design was used to provide data by ethnicity (African American, Hispanic, and White/Other), gender, and grade (4th, 8th, and 11th) from 2000 to 2002.
Two validated questionnaires (elementary and secondary) assessed self-reported PA and SA. Point-prevalence estimates and 95% confidence intervals were computed.
Over 70% of students reported vigorous PA on ≥3 days/week, but <50% participated in daily physical education. A significant percentage (30% to 50%) of students reported ≥3 hours per day in SA. Fourth-grade boys and girls reported equal PA; however, 8th and 11th grade girls reported lowered vigorous PA. African American 8th- and 11th-grade boys reported the highest PA, but African American children also reported the highest prevalence of SA.
Findings from this study highlight the disparities in physical and sedentary activities by gender, grade, and race/ethnicity, and the need to address these differences with programs and policy. In general, grade level and gender differences were more striking and consistent than racial/ethnic differences.

The purpose of this study was to conduct a secondary analysis by combining 2 pedometer data sets to describe and analyze pedometer-determined steps/day of children by ethnicity and metropolitan status.
Participants were 582 children (309 girls, 273 boys; 53% Hispanic, 26% Caucasian, 21% African American) age 10 to 11 years (M = 10.37 ± 0.48) attending 1 of 10 schools located in urban, suburban, and rural settings. Participants wore a research grade pedometer for at least 3 week/school days. Mean steps/ day were analyzed by gender, ethnicity, and metropolitan status.
Statistical analyses indicated 1) boys (12,853 ± 3831; P < .001) obtained significantly more steps/day than girls (10,409 ± 3136); 2) African American (10,709 ± 3386; P < .05) children accumulated significantly less steps/day than Hispanic (11,845 ± 3901) and Caucasian (11,668 ± 3369) children; and 3) urban (10,856 ± 3706; P < .05) children obtained significantly less steps/day than suburban (12,297 ± 3616) and rural (11,934 ± 3374) children.
Findings support self-report data demonstrating reduced physical activity among African American children and youth, especially girls, and among children and youth living in urban areas. Possible reasons for these discrepancies are explored.
