The Importance of Hydration

Introduction to what it means to be hydrated. How important is hydration for your health? How much fluid should you be drinking? Does the type of fluid you drink matter? What about when you exercise? Do you know what your sweat rate is

A Simulation Pedagogical Approach to Engaging Generalist Pre-service Teachers in Physical Education Online: The GoPro Trial 1.0

There has been a continuous increase in enrolments within teacher education programs in recent years delivered via online and external modes. Such levels of enrolment have raised discussion around the theory-practice nexus and whether pre-service teachers (PSTs) can optimally engage with practical learning components via online platforms. This paper provides insight into the potential and feasibility of using GoPro video technology as an innovation in online teacher education delivery of practical physical education (PE) classes. Upon completion of the university semester, qualitative data was collected detailing the generalist PSTs’ perceptions relating to the potential of using GoPro video footage to capture practical PE classes. Field note observations also documented implementation considerations for integrating GoPro technology into practical PE lessons. The findings from the GoPro trial provide valuable insight for teacher education providers for future planning and delivery of university practical PE classes onlin

Ulnar Collateral Ligament Reconstruction with Traditional Docking Compared to Novel Surgical Techniques

Background: Ulnar Collateral Ligament Reconstruction (UCLR) is a surgical procedure on one of the main ligaments that provides normal stability for the elbow joint against excessive valgus stress. Damage to this ligament is common in athletes performing overhead throwing activities, primarily baseball players, due to excessive valgus stress during the throwing motion. The most common form of treatment for this type of injury is reconstructive surgery of the ligament, especially if athletes wish to return to sport participation. This type of surgery is extremely invasive and requires extensive post-operative rehabilitation in order to facilitate return to play. To date, many surgical techniques have been proposed and evaluated, but there are no conclusive comparison studies on patient outcomes following UCLR. Purpose: The purpose of this paper is to analyze previous studies on UCLR techniques and determine if there is a single superior surgical method leading to improved biomechanical outcomes and decreased failure measures. Our focused clinical question was identifying if the traditional docking technique compared to novel docking techniques during UCLR superior in relation to biomechanical outcomes and failure measures in cadaveric tissue. Methodology: The study design in this paper is a critically appraised topic. Various scholarly databases such as PubMed, MEDLINE and SportDiscus were utilized to search for studies related to UCLR surgical techniques. After an initial search, a list of fifteen relevant studies were identified. Each study was then scrutinized and evaluated to meet predetermined inclusion criteria and a minimum score of 6/9 on the PEDro scale. All studies not meeting these requirements were excluded. This left a total of five articles which were then used to answer the clinical question for this paper. The inclusion criteria involved meeting a cadaveric age of 16-60 y, objective measures of valgus testing, angular displacement, stiffness and modes of failure as post-operative outcomes. Further, we included studies that had a minimum of seven cadaver pairs tested, and studies were required to compare traditional docking to at least one novel technique. Results: All five studies involved compared at least one novel surgical technique to the docking technique. Four studies found no significant overall difference between the native and reconstructed states of any surgical technique. One study found no overall significant difference, but did identify slight differences in biomechanical properties. Discussion: All conclusions from individual studies demonstrate comparable findings between all UCLR techniques. Biomechanics, kinematics and failure modes in the acute stages following surgery in cadavers are similar between UCLR techniques. Despite all that has been done, additional research is still necessary to determine a superior surgical technique

Health and Physical Education Teacher Education 2.0: Pre-service Teachers’ Perceptions on Developing Digital Twitter Skills

The advent of Web 2.0 technologies such as Twitter are reflective of an improved capacity for global educative collaboration. Yet there is an absence of research determining the potential of social media within Health and Physical Education Teacher Education (H-PETE). The aim of this paper was to therefore determine pre-service teachers’ (PSTs) perceptions of the potential of using Twitter within H-PETE training. The study was underpinned by a constructivist online learning framework. PSTs (n=35) enrolled at a regional Australian university were recruited to participate via online survey. Themes revealed PSTs perceived Twitter could be valuable during H-PETE for facilitating learning, technology engagement, capturing international insight, enhancing collaboration and communication. In contrast, PSTs described potential barriers to using Twitter relating to receiving adequate training, privacy, excessive technology use, determining Twitter’s functionality and application across educational contexts. Unpacking PSTs’ perceptions of the potential of Twitter within H-PETE can contribute to the pedagogical decisions made by teacher educators to improve social media uptake in PSTs

Should Educators be ‘Wrapping School Playgrounds in Cotton Wool’ to Encourage Physical Activity? Exploring Primary and Secondary Students’ Voices from the School Playground

Physical activity in school playgrounds has changed considerably over recent decades to reflect a climate of ‘surplus safety’. A growing culture of surplus safety can be attributed to a desire of parents and teachers responsible for children to protect school students from danger. The aim of this research was to examine students’ perceptions of playground safety influences on physical activity during school breaks from the perspectives of the ‘users’ of school playgrounds. Data collection consisted of seven focus groups (4 primary school & 3 secondary school) conducted across four schools (2 primary & 2 secondary). During this study, the focus group discussions consisted of 54 children (32 primary & 22 secondary; 50% females; 50% males). Social-Ecological Model levels of school playground safety influence identified by both primary and secondary school students included intrapersonal safety influences (risk taking, preventing boredom, misbehaviour); interpersonal safety influences (teacher responsibilities, teacher support, peer support, teacher intimidation and bullying/territorial issues); physical environment safety influences (surfacing, protection from the weather, safe structures, protective equipment, playground space, hydration, school security and passive smoking protection) and policy/organisational safety influences (designated play areas, playground rules, further supervision, maintenance). This research addresses an important gap in the literature by providing useful information for teacher educators of the multiple safety influences on students’ participation in playground physical activity

The Influences on Teaching Perspectives of Australian Physical Education Teacher Education Students: The First-Year Influences on Teaching Perspectives Exploratory (FIT-PE) Study

There has been a paucity of literature investigating the teaching beliefs and intentions of Australian physical education teacher education (PETE) students that enter teacher training. The First-year Influences on Teaching Perspectives Exploratory (FIT-PE) study explores the teaching perspectives of first year PETE students; including teaching perspectives predicted as being dominant and important for physical education teaching. The teaching perspectives inventory (TPI) was administered to 105 Australian PETE students. Independent t-tests and one-way ANOVA statistical tests were conducted to compare average teaching perspective summary scores across demographic variables. The FIT-PE study findings revealed 18 year olds (compared to 20-25 year olds) and PETE students from rural backgrounds (compared to regional) had significantly higher average summary scores for the transmission (content-oriented) teaching perspective. This paper provides reflective opportunities for teacher training programs of the underlying core teaching values (beliefs and intentions) of students at the entry point of PETE training

Rapid and robust spin state amplification

Electron and nuclear spins have been employed in many of the early demonstrations of quantum technology (QT). However applications in real world QT are limited by the difficulty of measuring single spins. Here we show that it is possible to rapidly and robustly amplify a spin state using a lattice of ancillary spins. The model we employ corresponds to an extremely simple experimental system: a homogenous Ising-coupled spin lattice in one, two or three dimensions, driven by a continuous microwave field. We establish that the process can operate at finite temperature (imperfect initial polarisation) and under the effects of various forms of decoherence.Comment: 5 pages, 2 figure
