A serious commitment to sport and exercise may predispose female athletes to the development of eating disorders. The energy restriction and accompanying menstrual disorders that are often associated with eating disorders may increase female athletes’ injury risks. The purpose of this study was to assess NCAA Division I, II, and III female collegiate cross country athletes’ weekly exercise time, rates of injury, menstrual dysfunction, and subclinical eating disorder risks. A paper-pencil survey was completed by athletes (mean age = 19.64 years) from NCAA Division I (n = 82), Division II (n = 103) and Division III (n = 115) colleges across the United States. Division I athletes spent significantly more weekly exercise time (M = 687.97 minutes) than Division II (M = 512.38 minutes, p = .0007) or Division III (M = 501.32 minutes, p = .0003) athletes. When examining rates of menstrual dysfunction, 23 percent reported amenorrhea or oligomenorrhea. Over 60 percent (64.3%) of the athletes reported a performance-related injury, with the knee being the most commonly injured site. 24 percent (23.7%) of the athletes reported having stress fractures. Scores for subclinical eating disorders for Division I athletes were significantly higher (M = 87.11) than Division III athletes (M = 82.94, p = .0042). Division I female athletes may be at an increased risk of developing subclinical eating disorders compared to those competing in Division II or III. Because early identification of those with subclinical eating disorders prevents the progression to eating disorders, further study is warranted.

Background:

This study evaluated a physical activity–related obesity model on mortality.

Methods:

Data from the 1999–2006 NHANES were used (N = 16,077), with follow-up through 2011. Physical activity (PA) was subjectively assessed, with body mass index (BMI) and waist circumference (WC) objectively measured. From these, 12 mutually exclusive groups (G) were evaluated, including: G1: Normal BMI, Normal WC and Active; G2: Normal BMI, Normal WC and Inactive; G3: Normal BMI, High WC and Active; G4: Normal BMI, High WC and Inactive; G5: Overweight BMI, Normal WC and Active; G6: Overweight BMI, Normal WC and Inactive; G7: Overweight BMI, High WC and Active; G8: Overweight BMI, High WC and Inactive; G9: Obese BMI, Normal WC and Active; G10: Obese BMI, Normal WC and Inactive; G11: Obese BMI, High WC and Active; and G12: Obese BMI, High WC and Inactive.

Results:

Compared with G2, the following had a reduced mortality risk: G1, G3, G5, G6, G7, G8, G9, and G11. Compared with G12, the following had a reduced mortality risk: G1, G3, G5, G7, G9, and G11. In each respective group for BMI and WC, the active group had a reduced mortality risk.

Conclusions:

Across all BMI and WC combinations, PA improved mortality risk identification.

The provocative and dynamic interrelationships between the social organization of sport, sexual orientation of women participants, and their concomitant perceptions and behavior represent a fertile area for social psychological research. Sport psychologists have largely avoided, through scholarly discourse, examining lesbianism in sport thereby perpetuating “the silence so loud that it screams.” The purpose of this paper is to identify the harmful intellectual and social consequences of this silence and to advance suggestions for future research directions based on emerging epistemology and theory. It is argued that if the silence is broken using depoliticized functionalist approaches such as sex-role identification and liberal humanism, this will only exacerbate the homophobia and heterosexism that hinders our intellectual pursuit of knowledge in this area and reify the heteropatricarchal oppression of lesbians participating in sport. The rigid socially-constructed isomorphism between sport and masculinity coupled with the social stigma of lesbianism within sport may only be transformed via a paradigmatic shift from traditional functionalism toward a social constructionist approach.

Background:

How addiction severity relates to physical activity (PA), and if PA moderates the relation between PA and lung function among smokers, is unknown. This study explored the independent and interactive associations of nicotine addiction severity and PA with lung function.

Methods:

The study used cross-sectional data from 343 adult smokers aged 40 to 79 participating in the 2009–10 and 2011–12 National Health and Nutrition Examination Survey. Assessed were the independent relations of nicotine addiction severity, as measured by the time to first cigarette (TTFC), and average daily minutes of moderate and vigorous PA with lung function ratio (FEV1/FVC). Additional analysis examined whether PA moderated the relationship between addiction severity and lung function.

Results:

Greater lung function was independently associated with moderate PA and later TTFC, but not vigorous PA, when controlling for cigarettes per day (CPD), past month smoking, ethnicity, years smoked, and gender (P-values < .05). PA did not moderate the association between addiction severity (TTFC) and lung function (P = .441).

Conclusion:

Among middle-aged to older smokers, increased PA and lower addiction severity were associated with greater lung function, independent of CPD. This may inform research into the protective role of PA and identification of risk factors for interventions.

This study explored in depth the process by which sport psychology ideas and techniques are diffused into elite-level swimming programs in the United States. Three stages in the diffusion process were examined: initial exposure, degree of receptivity, and rate of implementation. A questionnaire designed to measure this diffusion process was mailed to the 165 Level 5 coaches in the U.S. Sources through which coaches are exposed to sport psychology were identified, as well as factors influencing levels of receptivity and implementation. Intercorrelations among initial exposure, receptivity, and implementation were also examined and factors were identified that may reduce levels of receptivity and implementation. Findings suggest that despite only a moderate degree of exposure, coaches are generally receptive and willing to implement sport psychology into their programs. Major obstacles to both receptivity and implementation were generally related to structural aspects of amateur swimming in the U.S. or the sport psychology community. Identification of such factors can help the sport psychology community improve the process by which its knowledge base is diffused into the sporting community.

The purpose of this paper is to examine factors related to success in academic publishing for women in exercise science. Two trained investigators conducted hand searches of 7 prominent exercise science journals to ascertain the names of the most prolific women authors between 1991 and 1996. Seventeen (17) women, whose names will not be revealed (due to confidentiality), were identified. Following their identification, women were asked to submit a copy of their vita and complete a questionnaire related to scholarly productivity. Thirteen out of seventeen women agreed to participate in the study, yielding a response rate of 76%. Personal attributes that contributed most to their success in publishing were self-motivation, discipline, and perseverance. Situational or sociological factors mentioned were the availability of mentors, talented collaborators, and institutional or personal support. Some tips for maximizing productivity include having proper preparation and a narrow focus, and developing skills in writing, research design, and analysis. Women reported many gender-related barriers early in their careers, but these barriers faded with experience and reputation establishment. The two most frequent recommendations for ensuring successful collaborations with others were completing work in a timely fashion and being a team player. Sacrifices made for publishing included fewer social interactions and less time for leisure activities and vacations. With the exception of some barriers related to gender, our findings are in agreement with others who have examined correlates of productivity in mixed samples of men and women from a variety of fields.

The Theory of Planned Behavior (TPB) has been extensively used in predictive studies, but there have been considerably fewer experimental tests of the theory. One reason for this is that the guidance on developing concrete intervention strategies from the abstract theory is vague, and there are few exemplars of how to do this. The aim of this article is to provide such an exemplar. The development of an intervention to increase walking in the general public is described, based on the TPB, extended to include postvolitional processes. Identification of target constructs, elicitation of key salient beliefs underpinning these constructs, selection of appropriate behavior change techniques, and technique refinement. Each step is based on available evidence and consistent with theory. Perceived behavioral control (PBC) was identified as the key determinant of walking intentions, with an “intention-behavior gap” noted. A brief intervention was developed, using techniques to increase PBC by rehearsal of previous successful performance of behavior, along with planning techniques to translate motivation into behavior. This systematic approach taken should provide a model for others. The intervention has demonstrated efficacy in producing large changes in objectively measured walking behavior, in 2 separate evaluations reported elsewhere.

Background:

This study aimed to develop and evaluate the construct validity and reliability of modernized social cognitive measures relating to physical activity behaviors in adolescents.

Methods:

An instrument was developed based on constructs from Bandura’s Social Cognitive Theory and included the following scales: self-efficacy, situation (perceived physical environment), social support, behavioral strategies, and outcome expectations and expectancies. The questionnaire was administered in a sample of 171 adolescents (age = 13.6 ± 1.2 years, females = 61%). Confirmatory factor analysis was employed to examine model-fit for each scale using multiple indices, including chi-square index, comparative-fit index (CFI), goodness-of-fit index (GFI), and the root mean square error of approximation (RMSEA). Reliability properties were also examined (ICC and Cronbach’s alpha).

Results:

Each scale represented a statistically sound measure: fit indices indicated each model to be an adequate-to-exact fit to the data; internal consistency was acceptable to good (α = 0.63−0.79); rank order repeatability was strong (ICC = 0.82−0.91).

Conclusions:

Results support the validity and reliability of social cognitive scales relating to physical activity among adolescents. As such, the developed scales have utility for the identification of potential social cognitive correlates of youth physical activity, mediators of physical activity behavior changes and the testing of theoretical models based on Social Cognitive Theory.
