A Physical Profile of Elite Female Ice Hockey Players from the United States

Despite impressive numbers of hockey participants, there is little research examining elite female ice hockey players. Therefore, the purpose of this study was to describe the physical characteristics of elite female ice hockey players who were trying out for the 2010 U.S. Women\u27s Ice Hockey team. Twenty-three women participated in the study and were evaluated on: body mass (kg), height (cm), age (y) vertical jump (cm), standing long jump (cm), 1 RM front squat (kg), front squat/body mass (%), 1 RM bench press (kg), bench press/body mass (%), pull ups, and body composition (% body fat). Athletes in this sample were 24.7 + 3.1 years of age, and 169.7 + 6.9 cm tall; on average, they weighed 70.4 + 7.1 kg, and reported percent body fat of 15.8 + 1.9%. Mean vertical jump was 50.3 + 5.7 cm and standing long jump was 214.8 + 10.9 cm. Mean 1RM for upper body strength (bench press) was 65.3 + 12.2 kg (95.1 + 15.5% of body mass) and 1RM for lower body (front squat) was 88.6 + 11.2 kg (127.7 + 16.3% of body mass). This study is the first to report physical characteristics of elite female ice hockey players from the United States. Data should assist strength and conditioning coaches in identifying talent, testing for strengths and weaknesses, comparing future teams to these indicators, and designing programs that will enhance the performance capabilities of female ice hockey athletes

A Pilot Study Examining Exercise Self-Efficacy as a Mediator for Walking Behavior in College-Age Women

Since mechanisms of behavior change are not always evaluated in physical activity interventions, current interventions are limited until these mechanisms are better understood (Bauman, Sallis, Dzewaltowski, & Owen, 2002). Therefore, studies are needed that examine mediating variables, derived from theory, in the design, implementation, and evaluation of interventions. A mediator is a variable that must be included in an intervention in order for a specific change in a dependent variable or outcome to occur (MacKinnon, 2008). MacKinnon (2008) describes several methods of identifying mediators using statistical procedures, including the causal inference approach, difference in coefficients, product of coefficients, structural equation modeling and bootstrap estimates of the mediated effect

Gender-Specific Marketing Strategies Used by Sports Supplements: A Descriptive Study

While the use of sports supplements is common among athletes and active adults, the marketing strategies used by these sports supplement manufacturers remain unknown—especially relative to active and athletic women. This descriptive study aims to describe marketing strategies used, such as color choices, structure function claims, and picture choice, and analyze if there are gender-specific differences within the strategies. A total of 100 best-selling sports supplements were selected from three separate third-party websites. Food products, accessories, and kitchen appliances were excluded. Supplement main webpages and sports supplement-specific webpages were explored to determine which marketing strategies were used and if there were gender-specific differences. Of 169 sports supplement webpages reviewed, only 23.1% (n=39) included pictures that were only/majority female. Only 7.1% (n=12) of supplement bottles used feminine colors, while for supplement pages, only 8.3% (n=14) utilized feminine colors and 43.2% (n=73) used masculine colors. While the number of women athletes continues to grow, sports supplement manufacturers are not using strategies targeted to women. Future research should examine the reasons for this discrepancy and women’s perceptions of purchasing sports supplements targeted to men

A Structural Equation Model Examining the Cultural Relevance of Physical Self-Concept and Self-Esteem in Chinese Children

Objectives: The purposes of this study were to investigate: (1) whether three subscale scores (i.e.,body fat, appearance, and strength) and the global physical self-concept and global self-concept scores of the Physical Self-Description Questionnaire (PSDQ) are applicable to Chinese children; (2) whether there is a gender difference in these relationships; and (3) whether global physical self-concept acts as a mediator of global self-concept. Method: 320 Chinese children aged 7-12 years were recruited. The PSDQ was used to assess two global dimensions (global physical self-concept and global self-concept) and three specific dimensions (body fat, appearance, and strength) of self-worth. The children’s version of the silhouette matching task (SMT) was adopted from Marsh and Roche (1996) to measure children’s body perception. Results: The factor structure of the modified PSDQ model was applicable in young Chinese children, regardless of their gender. Results of structural equation model (SEM) indicated that the model was acceptable. The structural paths of the model and the mediating effect of global physical self-concept on global self-concept were discussed. Conclusion: The present study indicates that the physical self is an increasingly important correlate of self-esteem. It is particularly important relative to perceived self-presentation and social acceptance. Therefore, it is important to consider the impact of the physical self-concept on global self-concept from both cultural and worldwide perspectives

Predictors of Cycling in College Students

Objectives: To (1) assess cycling-related questions that have been added to the electronic version of the American College Health Association National College Health Assessment II (ACHA-NCHA), (2) examine cycling prevalence, and (3) identify predictors of cycling in college students. Participants: Predominately female (69%), undergraduate (89%), and white (85%) students (N = 949) from a large, urban, northwestern, bicycle-friendly university completed the electronic version of the ACHA-NCHA II. Methods: Thirty cycling-related questions were added to the ACHA-NCHA II and a subsample of questions was analyzed. Results: Cycling questions added to the ACHA-NCHA II scale were reliable and valid, based on the psychometric data analysis. More than half (59%) of this sample cycled; of those, 58% cycled for transportation and 44% for recreation. Facilitators and barriers to cycling were different for cycling in general and cycling for transportation. Conclusions: Cycling questions added to the ACHA-NCHA II can be utilized to enhance knowledge relative to cycling on college campuses

A 4-Year Profile of Game Demands in Elite Women\u27s Division I College Basketball

Workload for a Division I women’s collegiate basketball team (0.817 win percentage) was examined by: (a) season, (b) player position, and (c) game outcome (wins vs. losses). Female athletes (n = 6, mean 19.7 ± 1.5 years, at beginning of study) wore Catapult S5 units during 91.8% of games over a 4-year period. Average PlayerLoad, PlayerLoad per minute (PL·min-1), high inertial movement analysis (high-IMA), and jumps were quantified using Catapult Openfield software (version 1.14.1+). Data were checked for normality and log- or square-root-transformed when they were non-normal. A series of linear mixed model analyses were conducted to detect differences in PlayerLoad, PL·min-1, high-IMA, and jumps by season, position, and game outcome. PL·min-1 and jumps data were not normal, so they were transformed, analyses were run; because there were no differences in findings, data are reported in original units to allow for comparisons with other studies. Cohen’s d and confidence intervals were provided as additional information about the strength of reported differences. The 3 most consistent findings were that across a 4-year period, jumps increased, PL·min-1 was higher in guards compared with posts, and high-IMA was higher in losses compared with wins. Other workload patterns were inconsistent, and inappropriate for making conclusive statements. Therefore, comparing jumps across multiple seasons, PL·min-1 by player position and high-IMA in losses are important; in addition, all data can be used to profile National Collegiate Athletic Association Division I women’s basketball players and set game workload expectations

An Examination of Current Practices and Gender Differences in Strength and Conditioning in a Sample of Varsity High School Athletic Programs

Currently, little is known about strength and conditioning programs at the high school level. Therefore, the purpose of this research was to explore current practices in strength and conditioning for varsity high school athletes in selected sports. Specifically examined were: who administers programs for these athletes, what kinds of training activities are done, and whether the responsible party or emphasis changes depending on the gender of the athletes. Coaches of varsity soccer, basketball, and softball/baseball in three large Idaho school districts were asked to complete an online survey. Sixty-seven percent (32/48) of the questionnaires were completed and used for the study. The majority of coaches (84%) provided strength and conditioning opportunities for their athletes, although only 37% required participation. Strength training programs were designed and implemented primarily by either physical education (PE) teachers or head coaches. Compared to coaches of male athletes, coaches of female athletes were less likely to know the credentials of their strength coaches, and they were less likely to use certified coaches to plan and implement their strength and conditioning programs. Most programs included dynamic warm-ups and cool-downs, plyometrics, agility training, speed training, and conditioning, and most programs were conducted three days a week (76%) for sessions lasting between 30 and 59 minutes (63%). Compared to their female counterparts, male athletes were more likely to have required training, participate in strength training year round, and train using more sessions per week. This study provides additional information related to the practice of strength and conditioning in a sample of high school athletic teams

An Examination of the Effectiveness of an 8-Week Bikram Yoga Program on Mindfulness, Perceived Stress, and Physical Fitness

Previous research reports positive effects of yoga on health. The physical and psychological outcomes of participation in Bikram yoga are under-researched despite its increasing popularity, and this type of yoga may be significant with regards to stress management due to its unique method of practice. This study was designed to assess changes in levels of mindfulness, perceived stress, and physical fitness after participation in an 8-week Bikram yoga program. Fifty-one participants aged 20–54 years (mean, 31.57 years) were recruited by word of mouth from a large university located in the Northwestern United States. Participants attended a minimum of 20 Bikram sessions over 8 weeks. Changes in mindfulness (Five-Facet Mindfulness Questionnaire), perceived stress (Perceived Stress Scale), and physical fitness (resting heart rate, 1-mile walk, sit-and-reach, total-body rotation, and single-leg balance) were measured. Eight weeks of Bikram yoga improved mindfulness, perceived stress, cardiorespiratory endurance, flexibility and balance (p \u3c 0.01). Mindfulness was negatively correlated with perceived stress (r=−0.43, p \u3c 0.01) and resting heart rate (r=−0.30, p \u3c 0.05). The results show that Bikram yoga positively affected psychological and physical health in the sample population. This information can be used to further the understanding of mind-body based programs, and how Bikram yoga may give people the tools to decrease perceived stress, potentially having an effect on chronic stress-related illnesses

Predictors of Physical Activity on a College Campus with a High Proportion of Non-traditional Students

Background and purpose: Given the problem of obesity, physical inactivity and sedentary lifestyles among college students in the US, this study presents demographic, psychosocial, personal and environmental predictors of physical activity (PA) on an individual college campus with a high percentage of non-traditional students. Methods: The National College Health Assessment (NCHA) survey was completed by college students at a large Northwestern university [N = 949; Male = 292 (31.1%); female = 647 (68.9%); mean age = 26.5 (SD = 9.0) years] during Fall 2011. Results: Sixty-eight percent of participants did not meet both moderate to vigorous physical activity (MVPA) and strength exercise (SE) recommendations. Good perceived health status and on-campus housing status were associated with a higher probability of meeting the MVPA and SE recommendations (p <.05), with the former also predictive of SE. High Interest in PA, high PA knowledge, low stress, male gender and young age explained additional variance in meeting the SE recommendation (p <.05). Conclusion: Most students did not participate in the recommended level of MVPA and SE. On this campus, efforts directed to increasing PA knowledge might facilitate an increase in SE. Efforts to promote exercise as a stress reliever may also increase SE participation

Evaluation of an Internet–Short Message Service–Based Intervention for Promoting Physical Activity in Hong Kong Chinese Adolescent School Children: A Pilot Study

Evaluation of acceptability and preliminary efficacy of an Internet and short message service (SMS) intervention for promoting physical activity (PA) in Hong Kong Chinese school children. An 8-week quasi-experimental study non-randomly assigned 78 school children (mean age=12.8 years) to (a) an intervention group that received a stage-matched, Internet PA program two times a week and tailored SMS messages daily; or (b) a no-treatment control. Data were collected from September 2008 until June 2009. Acceptability measures included exposure rate and participant\u27s satisfaction. Efficacy measures were changes in stage of motivational readiness (SMR) and self-reported PA level. Intervention participants demonstrated significant pre-post increments in SMR (Z=−2.558, p=0.011) and self-reported PA level [F(1, 76)=4.50, p=0.04]. There was a non-significant trend between groups in both SMR (p=0.24) and PA (p=0.13). Despite the similar ratings of satisfaction between Internet (M=3.12±0.74) and SMS (M=3.12±0.84), participants displayed distinct patterns of exposure with 66% exhibiting a weekly login rate of 0.5 times/person and an average of 3.75 minutes/visit/person. In contrast, 79% of participants read an average of 1.3 SMS/person/week and 47% voluntarily replied to 3.8 SMS/person. These findings demonstrate the acceptability and preliminary efficacy of an Internet-SMS-based intervention for promoting PA in Hong Kong school children. The divergent exposure rates between the Internet and SMS may be a unique pattern for adolescents in early SMR. Future research should be cognizant of the importance of SMR since it may influence utilization and/or adherence
