Creating An Interprofessional Collaborative Research Opportunity For Physical And Occupational Therapy Students, Anne Fleischer, Mary Insana Fisher, Shirley P. O'Brien

Physical Therapy Faculty Publications

Physical therapy (PT) and occupational therapy (OT) professional associations assert the importance that entry-level therapists learn and apply the knowledge and skills necessary for interprofessional collaborative practice; however, the majority of PT and OT programs do not have the other discipline at their university. A challenge exists for the creation of a transparent active learning opportunity promoting interprofessional student engagement when the two professions do not reside in the same university. This case study provides a model for how to feasibly create an interprofessional experience for students in universities that do not include a complementary or collaborative allied health professional …

Barbosa, Alana De Sena Souza, Marco Bergamin, Vitor E. Valenti, Julien S. Baker, Guilherme L. Shimojo, Jonato Prestes, Whitley J. Stone, Danilo Sales Bocalini, Rogério Brandão Wichi

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 1198-1205, 2019. The physical demands of soccer combined with the rigor of the competitive season may have a substantial impact on autonomic modulation in field soccer athletes. The number of sudden death cases associated with soccer may be related to the physical training required to maintain performance and fitness, minimal time for recovery, and recurrent game participation. It is possible to identify individuals at risk of cardiovascular events by measuring heart rate variability (HRV), which is an indirect method for assessing autonomic activity. Therefore, the objective of this study was to analyze HRV before …

Running Economy - A Comprehensive Review For Passive Force Generation, Christos Ziliaskoudis, Song-Young Park, Sang-Ho Lee

Health and Kinesiology Faculty Publications

Running economy is considered a major determinant of distance running performance. Enhancing the body’s ability for passive force generation could have a positive effect on running economy by minimizing the energy cost required for the propulsion of the body. Thus, the purpose of this comprehensive review was to provide a list of modifiable factors that promote this ability. The interest was focused on lower-limb stiffness, as it is a factor of great influence and at the same time can be modified with training and specific biomechanical adjustments. Although it appears that no clear instructions can be provided to athletes and …

Embodied Gestalts: Unstable Visual Phenomena Become Stable When They Are Stimuli For Competitive Action Selection, Dobromir Dotov, Michael T. Turvey, Till D. Frank

Journal Articles

An animal’s environment is rich with affordances. Different possible actions are specified by visual information while competing for dominance over neural dynamics. Affordance competition models account for this in terms of winner-takes-all cross-inhibition dynamics. Multistable phenomena also reveal how the visual system deals with ambiguity. Their key property is spontaneous instability, in forms such as alternating dominance in binocular rivalry. Theoretical models of self-inhibition or self-organized instability posit that the instability is tied to some kind of neural adaptation and that its functional significance is to enable flexible perceptual transitions. We hypothesized that the two perspectives are interlinked. Spontaneous instability …

Technology In University Physical Activity Courses: A Mini-Ethnographic Case Study, Dannon G. Cox, Jennifer M. Krause, Mark A. Smith

The Qualitative Report

As younger generations become increasingly reliant on technology, higher educational institutions must continually attempt to stay with or ahead of the curve to foster 21st century teaching and learning. College and university physical activity courses (PACs) are encouraged to incorporate technology for effective pedagogical practices. No qualitative research has specifically examined the culture of PACs instructors’ attitudes and experiences with technology as a pedagogical tool. A mini-ethnographic case study explored the use of technology among seven graduate teaching assistants who shared their pedagogical experiences, teaching practices, and perceptions of technology within PACs. Using an interpretive phenomenological analysis, composite narrative accounts …

Adult males (n = 10) with >1 year RT experience performed six sets to failure with 90% of 10 repetition maximum in the squat, bench press, and pull-down. Changes (∆) from pre- to immediately (IP), 24 and 48 h post-RT were calculated for neuromuscular performance markers (counter-movement jump peak power and mean concentric bench press and squat velocity with load corresponding to 1.0 m∙s⁻¹) and perceived recovery and soreness scales. Post-waking natural logarithm of the root-mean square of successive …

Crises In The Aquatic Profession, Robert Keig Stallman

International Journal of Aquatic Research and Education

In this paper, I propose there are several crises in the aquatic profession and I explain what they are and how to address them using research and my own observations. I use an innovative questioning process to do this by asking you the reader a series of questions after which I explain each. The first crisis has to do with the quantity of trained swimming instructors relative to the population that they serve. In many western European and North American high income countries (HICs), the teacher:student ratios are declining and it is getting increasingly difficult to hire trained swim instructors. …
