Background:

Healthcare professionals are influential sources of health information and guidance for people of all ages. However healthcare providers do not routinely address physical activity (PA). Engaging health professionals in a national plan for physical activity will depend upon whether proven strategies can be found to promote PA within clinical settings.

Methods:

The literature on promoting PA in healthcare settings was reviewed, as were recommendations from healthcare organizations and evidence-gathering entities about whether and how PA should be promoted in healthcare.

Key recommendations:

Evidence is mixed about whether interventions based in healthcare settings and offered by healthcare providers can improve PA behaviors in patients. Brief stand-alone counseling by physicians has not been shown to be efficacious, but office-based screening and advice to be active, followed by telephone or community support for PA has proven effective in creating lasting PA behavior improvement. Healthcare delivery models that optimize the organization of services across clinical and community resources may be very compatible with PA promotion in health care. Because of the importance of PA to health, healthcare providers are encouraged to consider adding PA as a vital sign for each medical visit for individuals aged 6 years and older.

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.

Although group size has been one of the most frequently examined small-group variables, it has rarely been studied in sport. In Study 1 the effects of number of team members on cohesion and performance were examined. Teams of 3, 6, and 9 members participated in a 3-on-3 basketball league. Discriminant function analyses indicated that team size was related to pre-and postseason task cohesion and postseason social cohesion. Study 2 determined effects of action-unit size (number from one team on the field of action) on enjoyment and cohesion. Relationships between these outcomes and five more immediate outcomes were also investigated. As predicted, enjoyment and cohesion decreased as size increased. This decrease was also observed for the more immediate outcomes of exercise/fatigue, influence/responsibility, and organization/strategy whereas feelings of crowding increased with size. The best predictor of enjoyment was exercise/fatigue in smaller units and reduced influence/responsibility in large units. Organization/strategy was the best predictor of cohesion for all action-unit sizes.

Background:

Physical inactivity and related health consequences are serious public health threats. Effective strategies to facilitate and support active-living opportunities must be implemented at national, state, and local levels. San Antonio, Texas, health department officials launched the Active Living Council of San Antonio (ALCSA) to engage the community in developing a 3- to 5-year plan to promote active living.

Methods:

A steering committee set preliminary ALCSA aims and established a multisector membership structure modeled after the US National Physical Activity Plan (NPAP). ALCSA adopted governance standards, increased knowledge of physical activity and health, and engaged in an 18-month collaborative master plan writing process.

Results:

ALCSA selected overarching strategies and evidence-based strategies for each societal sector and adapted strategies to the local context, including tactics, measures of success, and timelines. Community and expert engagement led to a localized plan reflecting national recommendations, the Active Living Plan for a Healthier San Antonio.

Conclusion:

Multisector collaborations among governmental agencies and community organizations, which were successfully developed in this case to produce the first-ever local adaptation of the NPAP, require clearly defined expectations. Lessons learned in ALCSA’s organizational and plan development can serve as a model for future community-driven efforts to increase active living.

, & DeSouza, 2012 ). Organizational polices, the ways that programs are designed and delivered, and the nature and quality of the interactions that youth athletes have with coaches, parents, and peers all influence the optimization of positive development outcomes in the sport domain ( Fraser-Thomas et

Many initiatives have been developed to facilitate older adults’ engagement in physical activity (PA) and document its benefits. One example is Texercise, a 12-week program with a focus on increasing participants’ self-efficacy. The goal of this paper is to augment the knowledgebase of PA program implementation and dissemination by elucidating the experience of Texercise implementation as perceived by multiple stakeholders. We conducted 28 semistructured stakeholder interviews and categorized the responses into four preset themes: (1) program delivery and advocacy; (2) value/merit of the program; (3) successes/challenges of offering and sustaining the program; and (4) recommendations for enhancing implementation and delivery. We identified emergent subthemes through further analysis. Many perceptions that are broadly applicable to community organizations emerged. Our findings highlight the importance of stakeholder support when embedding PA programs in communities. Furthermore, the findings are crucial to understanding underlying processes that support widespread program dissemination and sustainability.

Gender differences in managerial aspirations and managerial potential have been advanced as possible explanations for the structuring of organizations along gender lines, with women concentrated in lower level jobs and under-represented in managerial positions. These hypothesized gender differences were examined in a sample of male and female physical education and non-physical education students. Analysis of variance results showed that the effects of gender, faculty, or their interaction on managerial aspirations were not significant. The main effects of aspiration level, faculty, and gender on the set of managerial potential variables were significant. Aspirants scored higher than nonaspirants on self-assurance, decisiveness, and need for dominance. Non-physical education students scored higher on need for dominance than did physical education students. Males were higher in need for autonomy and need for dominance, while females were higher in decisiveness.

Introduction:

The aim was to identify barriers and opportunities facing community health physiotherapists in delivering a home-based balance exercise program to address mild balance dysfunction and, secondly, to understand the perspectives of older people in adopting this program.

Method:

Focus groups, written surveys, and data recording sheets were used with nine older people and five physiotherapists. Focus groups were audio taped, transcribed, and coded independently by two researchers.

Results:

Thematic content analysis was undertaken. Emerging themes were: engaging in preventive health (various benefits, enhancing independence); adoption of strategies (acceptable design and implementation feasibility); exercising in context (convenience, practicality, and safety); and broader implementation issues (program design, proactive health messages, and a solid evidence base).

Conclusion:

The views of older people and physiotherapists were sought to understand the adoption of a previously successful home-based program for mild balance dysfunction. Understanding the unique context and circumstances for individuals and organizations will enhance adoption.

The sport of wrestling often encourages participants to engage in extreme weight loss practices in order to compete in a weight class one to three weight categories below normal weight. This review discusses the prevalence of the problem, methods wrestlers use to accomplish weight loss, and the health and performance consequences of rapid weight loss, with particular emphasis on weight cycling and minimal safe wrestling weight assessment. Some useful and practical recommendations for minimizing extreme weight loss practices are presented. Several state wrestling associations have adjusted their rules and regulations based on recommendations by organizations such as the American College of Sports Medicine to reduce the prevalence of the problem. Nevertheless, extreme weight loss continues to be a concern among health professionals, particularly with regard to health and performance.

The concept of motor equivalent combinations of arm muscles, or M-modes, was investigated during reaching to insert a pointer into a cylindrical target with and without an elbow perturbation. Five M-modes across 15 arm/scapula muscles were identified by principal component analysis with factor extraction. The relationship between small changes in the M-modes and changes in the position/orientation of the pointer were investigated by linear regression analyses. The results revealed a motor equivalent organization of the M-modes for perturbed compared with nonperturbed reaches, both with respect to hand position and orientation, especially in the first 100-ms postperturbation. Similar findings were obtained for motor equivalence computed based on changes in the joint configuration, although the kinematically defined motor equivalence was stronger for pointer orientation. The results support the hypothesis that the nervous system organizes muscles into M-modes and flexibly scales M-mode activation to preserve stable values of variables directly related to performance success.
