Sport psychology professionals have increasingly utilized technology for providing performance enhancement and clinical services. Some uncertainty exists amongst professionals to the ethical nature of providing services using technology. The purpose of this study was to survey Certified Consultants of the Association for Applied Sport Psychology (AASP) on the frequency and perceived ethicality of their technology use for providing performance enhancement and clinical services. A secondary purpose was to investigate differences in perceived ethicality between consultants with professional licensure compared to unlicensed professionals. Results suggest overall technology use for service delivery by consultants is low. Technologies used to provide clinical services displayed significantly lower ethical ratings compared to their use for performance enhancement purposes. Differences between licensed consultants and those who are unlicensed emerged for the ethical perceptions of providing performance enhancement services via email, cell phone, and videoconferencing, as well as for clinical services provided via cell phone.

Price dispersion reflects ignorance in the marketplace in which different prices exist from the same or different sellers for a similar good. One of the sources of price dispersion is uncertain demand for a business’s good or service. Ticket markets are good opportunities to examine a firm’s pricing strategy under demand uncertainty, because professional sports teams have to price their tickets well in advance of the actual event and before actual demand is known. The purpose of the present research is to examine the relationship between price dispersion and regular season average attendance in Major League Baseball. Using a two-step generalized method of moments (GMM) model, the present research finds that an increase in price dispersion leads to a decrease in average attendance.

Physical activity has clear health benefits but there remains uncertainty about how it affects health care costs.
To examine how physical activity is associated with changes in health expenditure for a national sample age 54 to 69 y, and estimate how this association varies across people with different chronic diseases and health behaviors.
Data were from the Health and Retirement Study, a national longitudinal survey of late middle age Americans.
Correcting for baseline differences in active and inactive groups, physical activity was associated with reduced health care costs of about 7% over 2 y (or $483 annually).
Regular physical activity in late middle age may lower health expenditure over time, and the effect is likely to be more pronounced for the obese, smokers, and individuals with some baseline health problems. While substantially large for the health care system, our estimates are much smaller than health-unadjusted comparisons or cross-sectional effects.
This article reports on time management in an elite sports context. It aims at characterizing how coaches experience dealing with athletes’ time management in a sport and academic institute and their constraints. Ten male coaches participated in this study. Each coach was asked to describe his time management activity during the season. Inductive and deductive analysis revealed two main results. The first showed the coaches dealt with a stringent set of constraints concerned with: (a) season organization, (b) training period and task sequencing, (c) the institute’s set times, and (d) the uncertainty linked to the evolution of training. The second emphasized that the coaches used three complex operating modes: (a) the use of organizational routines based on reference to past experience, (b) season shared time management, and (c) time management based on flexible plans. The results are discussed in relation to research that has considered planning and time management.
What do disability labels give us and what do they steal from us? How possible is it to live our lives without categories when life is necessarily categorical? In this brief provocation, I want to explore the disability labels through recourse to three perspectives that have much to say about categorization, disability, and the human condition: the biopsychological, the biopolitical, and, what I term, an in-between-all politics. It is my view that disability categories intervene in the world in some complex and often contradictory ways. One way of living with contradictions is to work across disciplinary boundaries, thus situating ourselves across divides and embracing uncertainty and contradiction to enhance all our lives. I will conclude with some interdisciplinary thoughts for the field of adapted physical activity.

The Canadian Sport Policy advocates for increased interaction among sport organizations as a means to create a more efficient and effective system. The purpose of this study was to explore the existence and nature of linkages among a network of community basketball providers. Network theory focuses on the interconnections of organizations by considering the structural, social, and economic bonds of cooperative behavior. Quantitative data were collected via a questionnaire and analyzed using network software UCINET 6 to assess the numbers and types of linkages among a network of community basketball organizations (n = 10) in one geographical region. Next, in-depth, semistructured interviews were conducted with leaders from the organizations and from their provincial/national governing bodies (n = 11) to assess the barriers to linkages among these organizations. Results indicated a loosely coupled network, wherein issues of power and dependence, uncertainty, and the lack of managerial structures to initiate and manage linkages prevailed.

Objective methods can improve accuracy of physical activity measurement in field studies but uncertainties remain about their use.
Children age 11 years from the Avon Longitudinal Study of Parents and Children (ALSPAC), were asked to wear a uni-axial accelerometer (MTI Actigraph) for 7 days.
Of 7159 children who attended for assessment, 5595 (78%) provided valid measures. The reliability coefficient for 3 days of recording was .7 and the power to detect a difference of 0.07 SDs (P ≤ .05) was > 90%. Measures tended to be higher on the first day of recording (17 counts/min; 95% CI, 10–24) and if children wore the monitor for fewer days, but these differences were small. The children who provided valid measures of activity were different from those who did not, but the differences were modest.
Objective measures of physical activity can be incorporated into large longitudinal studies of children.
This article uses economic theory to examine the variables that affect the competitive balance in a professional sports league and the impact of revenue sharing. The generally accepted proposition that revenue sharing does not affect the competitive balance in a profi t-maximizing league has been challenged by many. It is shown that the competitive balance and the impact of revenue sharing not only depend on the relative size of the market of the clubs, but that they are also affected by the objectives of the club owners and the importance to spectators of absolute team quality and uncertainty of outcome. Furthermore, the clubs’ hiring strategies, including the talent supply conditions, turn out to be important elements affecting competitive balance and the impact of revenue sharing.

Research describing load-monitoring techniques for team sport is plentiful. Much of this research is conducted retrospectively and typically involves recreational or semielite teams. Load-monitoring research conducted on professional team sports is largely observational. Challenges exist for the practitioner in implementing peer-reviewed research into the applied setting. These challenges include match scheduling, player adherence, manager/coach buy-in, sport traditions, and staff availability. External-load monitoring often attracts questions surrounding technology reliability and validity, while internal-load monitoring makes some assumptions about player adherence, as well as having some uncertainty around the impact these measures have on player performance This commentary outlines examples of load-monitoring research, discusses the issues associated with the application of this research in an elite team-sport setting, and suggests practical adjustments to the existing research where necessary.

The Journal of Physical Activity and Health seems likely to develop as a vehicle for practical, evidence-based answers to problems concerning physical activity and health, issues that have important implications for public health policy. There is strong epidemiological evidence for an association between the regular practice of physical activity and preventive or therapeutic benefit in a wide range of chronic health conditions,1-4 and already many professional groups have been eager to pre¬pare position statements, indicating their assessments of an appropriate minimum weekly dose of physical activity to maintain health.5 Unfortunately, there have been substantial discrepancies between successive recommendations, and uncertainties in the message are one probable factor, limiting its acceptance by both the general public and immediate health-care providers.6,7 The purpose of this brief commentary is to suggest some areas of investigation that would help in formulating a clear and consistent message. Topics discussed include the desired health outcome, the shape of the dose–response relationship, the impact of confounding variables, the quality of the evidence accepted, the basis for shaping the message, and the need for multiple messages.
