One of the more problematic methodological issues in attributional research has been the accurate classification, by researchers, of causal attributions made by respondents along causal dimensions. Closed-ended and open-ended approaches have been logical but limiting solutions to assessing attributions. Russell (1982) has the Causal Dimension Scale, a measure that allows the respondent to record a causal statement and indicate how he or she perceives that causal attribution in terms of causal dimensions. The present study examined the effects of winning and losing at table-tennis upon causal attributions using the Causal Dimension Scale. Reliability of the measure was assessed in a sport setting and the relationship between respondents' perceptions of attributions in terms of causal dimensions and judges' perception of the same were examined. The Causal Dimension Scale was found to be a reliable measure of how individuals perceive attributions in terms of causal dimensions. Winners' attributions were more internal, stable, and controllable than those of losers but attributions were of an internal, unstable, and controllable nature for both winners and losers.

The purpose of this study was to delineate and further define the behavioral, psychological, and physical characteristics of female athletes with subclinical eating disorders. Subjects consisted of 24 athletes with subclinical eating disorders (SCED) and 24 control athletes. Group classification was determined by scores on the Eating Disorder Inventory (EDI), the Body Shape Questionnaire (BSQ), and a symptom checklist for eating disorders (EDI-SC). Characteristics representative of the female athletes with subclinical eating disorders were derived from an extensive health and dieting history questionnaire and an in-depth interview (the Eating Disorder Examination). Energy intake and expenditure (kcal/d) were estimated using 7-day weighed food records and activity logs. The characteristics most common in the female athletes with subclinical eating disorders included: (a) preoccupation with food, energy intake, and body weight; (b) distorted body image and body weight dissatisfaction; (c) undue influence of body weight on self-evaluation; (d) intense fear of gaining weight even though at or slightly below (-5%) normal weight; (e) attempts to lose weight using one or more pathogenic weight control methods; (g) food intake governed by strict dietary rules, accompanied by extreme feelings of guilt and self-hatred upon breaking a rule; (h) absence of medical disorder to explain energy restriction, weight loss, or maintenance of low body weight; and (i) menstrual dysfunction. Awareness of these characteristics may aid in more timely identification and treatment of female athletes with disordered eating patterns and, perhaps, prevent the development of more serious, clinical eating disorders.

The primary purpose of this study was to determine whether tests performed at the National Hockey League (NHL) Combine could distinguish draft status (ie, the round selected). A secondary aim was to provide performance ranges and percentiles for each of the dependent variables.
A retrospective, cross-sectional study design was used with performance data and draft order from 2001, 2002, and 2003 Combine participants. Draft round was divided into 5 classifications (rounds 1, 2, 3, 4, and 5 through 9), and performances on 12 physical tests served as dependent variables. Three multiple analyses of covariance (MANCOVAs) were used to determine the significance of performance scores at the NHL Combine on draft selection. Age (years), body mass (kg), height (cm), and percentage body fat were treated as covariates.
Overall, MANCOVA results indicated no significant effect of performance on draft selection for 2001, 2002, or 2003. Subsequent univariate tests revealed that no single dependent variable was able to distinguish between draft rounds for any of the 3 years sampled.
Using draft status as an indicator of ice hockey performance, it appears that off-ice tests cannot accurately predict ice hockey playing ability in an elite group of athletes. This might stem from homogeneity of the Combine participants, a lack of validity of the tests, or other factors (eg, on-ice hockey skills, psychological variables, etc) that play a role in draft selection.

To determine the day-to-day variability of older adults’ physical activity, and to evaluate the accuracy of the 10,000-step goal for classifying whether older adults obtain 30 min of MVPA.
Ninety-one adults ages over 60 y wore a Yamax pedometer and Actigraph accelerometer for 7 days. Interday reliability was estimated via two-way ANOVA ICCs, and classification accuracy was evaluated via sensitivity, specificity, and ROC curve analysis.
Interday reliability was high; four of five outcome measures had a reliability of ≥.80 with only 2 days of data. The 10,000-step cut point had high accuracy for identifying days with less than 30 min of MVPA, but poor accuracy for identifying days with more than 30 min of MVPA.
Day-to-day variability in physical activity is lower in older adults than other age groups. The 10,000-step goal is inadequate for determining whether daily physical activity includes 30 min of MVPA in this population.

The purposes were 1) to determine if different leisure-time sedentary behaviors (LTSB), such as TV/video/video game viewing/playing (TV), reading for pleasure (reading), and nonschool computer usage, were associated with childhood overweight status, and 2) to assess the social-ecological correlates of LTSB.
The analytic sample was 33,117 (16,952 boys and 16,165 girls) participants from the 2003 National Survey of Children’s Health. The cut-point for excessive TV and nonschool computer usage was ≥ 2 hr/day. High quantities of daily reading for pleasure were classified as ≥ 31 min/day. Weighted descriptive characteristics were calculated on the sample (means ± SE or frequency). Logistic regression models were used to determine if the LTSB were associated with overweight status and to examine social-ecological correlates.
Over 35% of the sample was overweight. Odds of being overweight were higher in the 2 to 3 hr/day (OR: 1.48, 95% CI: 1.24, 1.76) and ≥ 4 hr/day (OR: 1.52, 95% CI: 1.22, 1.91) daily TV groups compared with none. Reading and nonschool computer usage was not associated with being overweight.
TV was associated with overweight classification; however, nonschool computer usage and reading were not. Several individual, family, and community correlates were associated with high volumes of daily TV viewing.
The growth of sport psychology has brought many positive advances and claims for achievement, but it has also brought controversy. Debate has beset the profession concerning classification (psychologist or consultant?), role (clinician or educator?), clientele (coach, athlete, or administrator?), ethics (whose purpose is to be served and who is being threatened?), and process (performance enhancement, winning, or personal fulfillment?). In this paper, the educational consultant in higher education is offered as a role model to help reduce the confusion and refocus attention on a more widely applicable role. Most sport psychologists today deal directly with athletes, usually elite athletes. However, as with physical skills, psychological skills require time and effort to fully develop. In order to address this time factor, this paper takes the stance that there is a growing need to train experts in the field to focus their efforts on the coach rather than the athlete. The consulting role, focus, and process suggested here could be of value to interested personnel at all levels of sport, and could provide a means for all participants to realize their fullest potential.

Evidence suggests reports describing the reliability of leg-spring (kleg) and joint stiffness (kjoint) measures are contaminated by artifacts originating from digital filtering procedures. In addition, the intraday reliability of kleg and kjoint requires investigation. This study examined the effects of experimental procedures on the inter- and intraday reliability of kleg and kjoint. Thirty-two participants completed 2 trials of single-legged hopping at 1.5, 2.2, and 3.0 Hz at the same time of day across 3 days. On the final test day a fourth experimental bout took place 6 hours before or after participants’ typical testing time. Kinematic and kinetic data were collected throughout. Stiffness was calculated using models of kleg and kjoint. Classifications of measurement agreement were established using thresholds for absolute and relative reliability statistics. Results illustrated that kleg and kankle exhibited strong agreement. In contrast, kknee and khip demonstrated weak-to-moderate consistency. Results suggest limits in kjoint reliability persist despite employment of appropriate filtering procedures. Furthermore, diurnal fluctuations in lower-limb muscle-tendon stiffness exhibit little effect on intraday reliability. The present findings support the existence of kleg as an attractor state during hopping, achieved through fluctuations in kjoint variables. Limits to kjoint reliability appear to represent biological function rather than measurement artifact.

The association between light-intensity activity and cardiovascular disease risk is not well understood. The purpose of this study was to determine the association of light-intensity activity with census-based occupational activity classifications and cardiovascular risk factors among Mexican American adults.
118 Mexican American adults (68.6% female) provided cross-sectional accelerometer and biological data. Self-reported occupations were classified by activity level (sedentary, low, moderate). Participants were classified as At-Risk for BMI, glucose, triglycerides, HDL, blood pressure, waist circumference, and percent body fat.
Participants engaged in > 5 hours of light-intensity activity on average, and those in sedentary occupations engaged in fewer light-intensity activity minutes than low-active or moderately active workers (P < .001). Self-reported occupation explained 14% of the variation in light-intensity activity (P < .001). Participants in moderately active occupations were at increased risk for high %body fat than other workers (P = .01), but no other associations between occupation and cardiovascular risk were detected.
Early work in physical activity underscored the importance of occupational activity. This study presents evidence of a dose-response association for light-intensity activity by occupational category such that workers in sedentary occupations had less light-intensity activity than employees in more active occupations. Future research on how light-intensity activity derived from occupation may reduce the risk of chronic disease will contribute to improved interventions as light-intensity activity participation may be more feasible than meeting current physical activity guidelines.

The authors’ aim was to examine the prevalence of (daily) dietary-supplement (DS) use among elite adolescent athletes and to differentiate use by different types of DS according to their function. Data were analyzed for associations between users of these DS types, sociodemographic, sport-specific characteristics, and opinion on the need for DS. In addition, sources of supply and information were examined. In the framework of the GOAL Study, 1,138 German elite adolescent athletes (14–18 yr) answered questions about DS. The data were analyzed to identify groups at risk for using DS after a classification by supplemental function. Of the young athletes, 91.1% reported DS use during the previous month. (Daily) DS use was significantly associated with sex, kind of sport, and the weekly duration of sporting activity. Furthermore, some athletes were required to use DS by their sporting organization. DS use was more likely in these athletes than in those whose sporting organizations had no such requirement. Overall, DS with short- and long-term supplemental function were mostly associated with the use of magnesium. However, DS with medium-term muscle-building function played an important role among daily users. The main source of information about DS was coaches; main source of supply was parents. Professional education is urgently needed, as 9 out of 10 athletes used DS, and strong positive opinions toward the use of DS were present, particularly in the DS users.

The development of positive attitudes toward physical education has been a longstanding and desirable goal of the program of physical education. The intent of this investigation was to identify those aspects of the program students reported as turning them on to or turning them off from physical education. The critical incident report was the tool used to gather information. The subjects (N = 100) classified the reported incidents as either positive or negative, and their comments were then categorized into five broad categories: (a) teacher, (b) curriculum, (c) atmosphere of the classroom, (d) peer behavior, and (e) perceptions of self. Further classification occurred within each category. The results indicated that the items most frequently mentioned in relation to both positive and negative attitudes related to the teacher and the curriculum. Some interesting patterns evolved both within and between the various categories. The most encouraging aspect of the investigation is that the great majority of causal determinants of negative attitudes are amenable to change. If physical educators value the goal of developing positive attitudes toward physical education, then information gathered in studies such as this should prove valuable to both current physical educators and those involved in teacher education programs.
