Over the past 18 years, Zelaznik and colleagues have promoted what is known as the event-emergent timing distinction. According to this framework, control of timing can be based upon a neurological clock-like process or upon an emergent process. I review the highlights of this research program that supports this distinction, then describe a new line of research that examines whether timing is a goal of the task or a consequence of other movement constraints. These results highlight the importance of goals in the control of timing.

The neural control of balance during locomotion is currently not well understood, even in the light of considerable advances in research on balance during standing. In this paper, we lay out the control problem for this task and present a list of different strategies available to the central nervous system to solve this problem. We discuss the biomechanics of the walking body, using a simplified model that iteratively gains degrees of freedom and complexity. Each addition allows for different control strategies, which we introduce in turn: foot placement shift, ankle strategy, hip strategy, and push-off modulation. The dynamics of the biomechanical system are discussed using the phase space representation, which allows illustrating the mechanical effect of the different control mechanisms. This also enables us to demonstrate the effects of common general stability strategies, such as increasing step width and cadence.
The last decade has witnessed an increase in the number of moderate to large-scale nonpharmacologic stroke recovery trials. While a majority, having tested the superiority of a particular evidence-based intervention, returned negative findings, the rehabilitation research community has gained an important perspective for future efforts. We offer our interpretation first, on why most of the past decade’s trials failed in the sense of not supporting the primary superiority hypothesis, and, second, we provide our perspective on how to solve this problem and thereby inform the next generation of neurorehabilitation clinical trials. The first large-scale randomized controlled trial (RCT) ever conducted in neurorehabilitation was the Extremity Constraint Induced Movement Therapy Evaluation (EXCITE) trial. The majority of stroke recovery trials that followed were based on a prevailing, but as yet immature science of brain-behavior mechanisms for recovery and limited practical know-how about how to select the most meaningful outcomes. The research community had been seduced by a set of preclinical studies, ignited by the 1990’s revolution in neuroscience and an oversimplified premise that high doses of task-oriented training was the most important ingredient to foster recovery. Here, we highlight recent qualitative and quantitative evidence, both mechanistic and theory-driven, that integrates crucial social and personal factors to inform a more mature science better suited for the next generation of recovery-supportive rehabilitation clinical trials.
3 WINS Fitness is a student-delivered free exercise program for the community delivered in public parks. We believe this program, which operates without external funding and has been sustained for 6 years, is one significant solution to reducing the level of physical inactivity in the United States. The operative 3 WINS in our program are participant health, community health, and student professional development. The primary focus has been underserved communities, and our current eight programs in Los Angeles, serve over 300 participants regularly. Three challenges to the program are student empowerment, faculty understanding and involvement, and establishing the relationship between university and parks, which represent a vital partnership. However, the accomplishment of undergraduate students having such a dynamic impact on public health underscores the need for encouraging this sustainable and innovative strategy to increase the physical activity levels of communities across America.

Successful campus-community partnerships provide universities enhanced visibility in the community, and offer university students opportunities to engage in real-world educational experiences through service learning and internships. In addition, the participating community agency/program benefits from an infusion of ambitious students that can help the agency/program further its mission, and increase its visibility and reach. Within the areas of health promotion and wellness, campus-community partnerships have become an essential component in the delivery of prevention services and the development of public health infrastructure. The purpose of this paper is to share the experiences of two universities in their development of campus-community partnerships in the areas of health and wellness.

Many kinesiology departments engage in partnerships that aim to promote positive youth development through physical activity. These partnerships are often enhanced by mutually beneficial goals and shared decision making between university and community partners. This paper describes how sport has been at the center of two university-community partnerships that have helped to teach life skills to youth. We draw upon our experience working with community partners to illuminate challenges and opportunities for youth-focused partnerships. The programs include an emphasis on sustainability. As kinesiology programs continue to enhance their efforts to partner and support youth development, case studies such as this may help inform our efforts.

This paper explores the use of collaboration theory and the consensus building framework to develop institutional strategic alliances at two North American postsecondary institutions. Collaboration between institutional and/or external partners offers rich opportunities to develop creative programming that provides students with opportunities for service learning situated in a well-planned curriculum. The collaboration development capitalizes on mutually beneficial outcomes for all partners and affords more informed decision making and impact than if partners were working individually. This paper highlights two successful partnerships and outlines the future direction of those collaborative alliances.

Civic engagement and service learning opportunities provide students with unique real-world experiences they are unable to acquire in a traditional in-class setting. Students develop a commitment to the community in which they live, exposure to other populations, leadership abilities, skills to work successfully within a team, and a chance to learn from failure. The Carnegie Foundation for the Advancement of Teaching has recognized the importance of such opportunities and has added the Community Engagement Classification to the restructured Carnegie Classifications of Institutions of Higher Education. The purpose of this paper is to provide a synthesis of the literature that addresses civic engagement and service learning opportunities and to describe a university class that was designed to provide undergraduate students with a capstone service learning experience promoting wellness for older adults in the community. Data that were collected to evaluate the success of the class are also described.

Temple University Owls Athletic Training Society (OATS), committed to education and community involvement, formed a relationship with Lanning Square Elementary School (LSE). Located less than 10 miles from campus in Camden, NJ, a high incidence of poverty, violence, and one-parent families is the norm. Through a grant, OATS adopted the fifth-grade classes at LSE for 1 year, beginning with letter exchanges between OATS students and elementary students. OATS traveled to LSE for their holiday party, met their pen pals, and provided healthy snacks. In the spring, the LSE completed a health/wellness unit and visited Temple. Students shared several health activities including learning about bones/muscles in the anatomy laboratory, stretching properly, and exercising. They received lunch and Temple mementos. OATS raised money the following year to continue the project. This allowed OATS and administrators to participate positively in our community, promote diversity, and introduce healthy lifestyles to youngsters.
