Is there a link between previous exposure to sport injury psychology education and UK sport injury rehabilitation professionals' attitudes and behaviour towards sport psychology?

Objectives: The use of sport psychology strategies during sport injury rehabilitation can lead to several positive outcomes such as improved adherence and self-efficacy. The purpose of this study was to compare the sport psychology related attitudes and behaviours of UK sport injury rehabilitation professionals (SIRPs) who had studied the psychological aspects of sport injury to those who had not. Participants and design: Ninety-four SIRPs (54 physiotherapists and 40 sports therapists with a mean of 9.22 years' experience of working in sport) completed an online survey and were grouped according to their level of previous exposure to sport injury psychology education at an undergraduate/postgraduate level. Analyses were undertaken to establish whether there were any differences in sport psychology related attitude (MANOVA), usage (MANOVA), and referral behaviours (chi square) between the groups. Results: The MANOVA and chi square tests conducted revealed that those who had studied the psychological aspects of sport injury reported using significantly more sport psychology in their practice and making more referrals to sport psychologists. Conclusions: It was concluded that sport injury psychology education appears to be effective in increasing the sport psychology related behaviours (use of sport psychology and referral) of SIRPs and should be integrated into professional training

The impact of a sport psychology education intervention on physiotherapists

The purpose of this study was to measure the impact of an online sport psychology education module on the attitudes and behaviours of qualified sports physiotherapists in the UK. Ninety-five sport physiotherapists studied either a sport psychology module or a control module, and their attitudes and behaviours towards sport psychology were measured prior to studying the module and at three points over a six-month period following its completion. It was found that those who had studied the sport psychology module demonstrated an improvement in their attitudes towards sport psychology immediately following its completion that was significantly higher than those who had studied the control module. Use of sport psychology also increased following the sport psychology module, with significant differences seen between the intervention and control group on the sport psychology subscale, indicating that those who had studied the sport psychology module were integrating more sport psychology techniques into their practice than those who had studied the control module. It was concluded that the online sport psychology module was effective in improving the attitudes and behaviours of UK physiotherapists and that more sport psychology education opportunities should be made available

Baffle Type Energy Dissipator for Pipe Outlets

The baffle type energy dissipator described in this paper was developed through laboratory experimentation for use in soil conservation work. It is designed to reduce the energy in high velocity pipe flow so that the water may be discharged safely into an erodible channel. This structure can be adapted to meet the many field conditions encountered in erosion control work in agriculture and elsewhere, such as at pipe outlets draining terraces or ditches, highway culverts, and drop inlet spillway outlets. Pipe sizes commonly used in such applications range from 10 to 48 in in diameter and have flows from 10 to 250 cfs discharging into channels of various widths

Interactions of short-term and chronic treadmill training with aging of the left ventricle of the heart

With aging, there is a decline in cardiac function accompanying increasing risk of arrhythmias. These effects are likely to be mechanistically associated with age-associated changes in calcium regulation within cardiac myocytes. Previous studies suggest that lifelong exercise can potentially reduce age-associated changes in the heart. Although exercise itself is associated with changes in cardiac function, little is known about the interactions of aging and exercise with respect to myocyte calcium regulation. To investigate this, adult (12 months) and old (24 months) C57/Bl6 mice were trained using moderate-intensity treadmill running. In response to 10 weeks’ training, comparable cardiac hypertrophic responses were observed, although aging independently associated with additional cardiac hypertrophy. Old animals also showed increased L- and T-type calcium channels, the sodium–calcium exchange, sarcoendoplasmic reticulum calcium ATPase, and collagen (by 50%, 92%, 66%, 88%, and 113% respectively). Short-term exercise training increased D-type and T-type calcium channels in old animals only, whereas an increase in sodium–calcium exchange was seen only in adult animals. Long-term (12 months) training generally opposed the effects of aging. Significant hypertrophy remained in long-term trained old animals, but levels of sarcoendoplasmic reticulum calcium ATPase, sodium–calcium exchange, and collagen were not significantly different from those found in the adult trained animals

The cardiomyocyte "redox rheostat": Redox signalling via the AMPK-mTOR axis and regulation of gene and protein expression balancing survival and death.

Reactive oxygen species (ROS) play a key role in development of heart failure but, at a cellular level, their effects range from cytoprotection to induction of cell death. Understanding how this is regulated is crucial to develop novel strategies to ameliorate only the detrimental effects. Here, we revisited the fundamental hypothesis that the level of ROS per se is a key factor in the cellular response by applying different concentrations of H2O2 to cardiomyocytes. High concentrations rapidly reduced intracellular ATP and inhibited protein synthesis. This was associated with activation of AMPK which phosphorylated and inhibited Raptor, a crucial component of mTOR complex-1 that regulates protein synthesis. Inhibition of protein synthesis by high concentrations of H2O2 prevents synthesis of immediate early gene products required for downstream gene expression, and such mRNAs (many encoding proteins required to deal with oxidant stress) were only induced by lower concentrations. Lower concentrations of H2O2 promoted mTOR phosphorylation, associated with differential recruitment of some mRNAs to the polysomes for translation. Some of the upregulated genes induced by low H2O2 levels are cytoprotective. We identified p21Cip1/WAF1 as one such protein, and preventing its upregulation enhanced the rate of cardiomyocyte apoptosis. The data support the concept of a "redox rheostat" in which different degrees of ROS influence cell energetics and intracellular signalling pathways to regulate mRNA and protein expression. This sliding scale determines cell fate, modulating survival vs death

Optimising in situ gamma measurements to identify the presence of radioactive particles in land areas

High-coverage in situ surveys with gamma detectors are the best means of identifying small hotspots of activity, such as radioactive particles, in land areas. Scanning surveys can produce rapid results, but the probabilities of obtaining false positive or false negative errors are often unknown, and they may not satisfy other criteria such as estimation of mass activity concentrations. An alternative is to use portable gamma-detectors that are set up at a series of locations in a systematic sampling pattern, where any positive measurements are subsequently followed up in order to determine the exact location, extent and nature of the target source. The preliminary survey is typically designed using settings of detector height, measurement spacing and counting time that are based on convenience, rather than using settings that have been calculated to meet requirements. This paper introduces the basis of a repeatable method of setting these parameters at the outset of a survey, for pre-defined probabilities of false positive and false negative errors in locating spatially small radioactive particles in land areas. It is shown that an un-collimated detector is more effective than a collimated detector that might typically be used in the field

PIRATE: A Remotely-Operable Telescope Facility for Research and Education

We introduce PIRATE, a new remotely-operable telescope facility for use in research and education, constructed from 'off-the-shelf' hardware, operated by The Open University. We focus on the PIRATE Mark 1 operational phase where PIRATE was equipped with a widely- used 0.35m Schmidt-Cassegrain system (now replaced with a 0.425m corrected Dall Kirkham astrograph). Situated at the Observatori Astronomic de Mallorca, PIRATE is currently used to follow up potential transiting extrasolar planet candidates produced by the SuperWASP North experiment, as well as to hunt for novae in M31 and other nearby galaxies. It is operated by a mixture of commercially available software and proprietary software developed at the Open University. We discuss problems associated with performing precision time series photometry when using a German Equatorial Mount, investigating the overall performance of such 'off-the-shelf' solutions in both research and teaching applications. We conclude that PIRATE is a cost-effective research facility, and also provides exciting prospects for undergraduate astronomy. PIRATE has broken new ground in offering practical astronomy education to distance-learning students in their own homes.Comment: Accepted for publication in PASP. 14 pages, 11 figure

The Reliability of an Abbreviated Test of Alertness

In certain types of work a short test of mental alertness is quite important: (1) because of the lack of time and means required to administer a full length test, and (2) because of the motivation of the examinees. The Otis Self-Administering Test has met this demand to some extent but it implies a certain amount of education and takes at least 20 minutes. A survey of test materials indicated some coml1ination of the Army Alpha and Beta tests had possibilities for this type of measuring instrument. A research was undertaken to adapt some of these types of materials to a short test of alertness
