The multi-stage fitness test as a predictor of endurance fitness in wheelchair athletes

Abstract

The aims of this study were two-fold: (1) to consider the criterion-related validity of the multi-stage fitness test (MSFT) by comparing the predicted maximal oxygen uptake ([Vdot]O_2max) and distance travelled with peak oxygen uptake ([Vdot]O_2peak) measured using a wheelchair ergometer (n = 24); and (2) to assess the reliability of the MSFT in a sub-sample of wheelchair athletes (n = 10) measured on two occasions. Twenty-four trained male wheelchair basketball players (mean age 29 years, s = 6) took part in the study. All participants performed a continuous incremental wheelchair ergometer test to volitional exhaustion to determine [Vdot]O_2peak, and the MSFT on an indoor wooden basketball court. Mean ergometer [Vdot]O_2peak was 2.66 litres · min^?1 (s = 0.49) and peak heart rate was 188 beats · min^?1 (s = 10). The group mean MSFT distance travelled was 2056 m (s = 272) and mean peak heart rate was 186 beats · min^?1 (s = 11). Low to moderate correlations (ρ = 0.39 to 0.58; 95% confidence interval [CI]: ?0.02 to 0.69 and 0.23 to 0.80) were found between distance travelled in the MSFT and different expressions of wheelchair ergometer [Vdot]O_2peak. There was a mean bias of ?1.9 beats · min^?1 (95% CI: ?5.9 to 2.0) and standard error of measurement of 6.6 beats · min^?1 (95% CI: 5.4 to 8.8) between the ergometer and MSFT peak heart rates. A similar comparison of ergometer and predicted MSFT [Vdot]O_2peak values revealed a large mean systematic bias of 15.3 ml · kg^?1 · min^?1 (95% CI: 13.2 to 17.4) and standard error of measurement of 3.5 ml · kg^?1 · min^?1 (95% CI: 2.8 to 4.6). Small standard errors of measurement for MSFT distance travelled (86 m; 95% CI: 59 to 157) and MSFT peak heart rate (2.4 beats · min^?1; 95% CI: 1.7 to 4.5) suggest that these variables can be measured reliably. The results suggest that the multi-stage fitness test provides reliable data with this population, but does not fully reflect the aerobic capacity of wheelchair athletes directly.     

Supporting Veteran Transitions to the Academic Setting: VA on Campus

In this case study, we assessed academic functioning, service satisfaction, and needs of student veterans at a community college who had accessed the Veterans Health Administration (VHA) Student Veteran Health Program (SVHP) (n = 36). The SVHP provides outreach and behavioral health services directly on a large community college campus to overcome common barriers to engagement in mental health care (e.g., distance from a VA medical center). Academic difficulties that were most commonly reported were in the areas of retention of information, meeting deadlines, and cooperation with other students. Overall, the majority of student veterans who received services in the SVHP were satisfied (76.5%). Services targeting attention and concentration and utilization of educational benefits were highlighted as important by student veterans. This case study of VA services delivered within the community college setting provides important insights into how to design VA services to target the needs of student veterans. Specific recommendations for supporting student veterans on a community college campus are discussed.     

A combined microfluidic-microstencil method for patterning biomolecules and cells

Despite the myriad of soft lithography based micropatterning methods available to researchers, it is still challenging to define small features (10–100 μm) that are spaced far apart (1–10 mm). In this report, we describe a combined microfluidic-microstencil patterning method that can produce multifunctional substrates of small features, O(10 μm), with a large pitch, O(1 mm). In that, we fabricate microstencils using an UV curable polyurethane (Norland Optical Adhesive 81) with dense arrays of 10–100 μm holes. Overlaying arrays of microfluidic channels over these microstencils allow for the control of the spacing between features and the ability to pattern multiple substrates. We show that this method is capable of patterning soluble proteins, fibrillar insoluble collagen, liposomes, cells, and nanoparticles. We demonstrate the utility of the method by measuring platelet adhesion under flow to three adhesive proteins (insoluble fibrillar collagen, laminin, and reconstituted acid solubilized collagen fibers) in a single assay.     

Implementing the 2014 SEND reforms in England: perspectives from SENCOs

This article is based on research conducted within two years of the 2014 SEND (special educational needs and disability) reforms being in force and reports on the experiences of five SENCOs (special educational needs coordinators) on implementing the reforms in London schools. The research was conducted primarily to inform professional practice and improve delivery of the principles underpinning the reforms. The research deployed an adapted version of SWOT analysis as a tool for seeking the views of SENCOs on the perceived benefits and challenges of the SEND reforms. The findings demonstrate that SENCOs broadly support the principles of the reforms. However, SENCOs find some of the procedures in the 2015 SEND Code of Practice as proving problematic. There still remains a significant focus on managing administrative processes, rather than bringing about a fundamental change to school culture and educational provision. The article concludes by making several recommendations on ways to reduce bureaucracy for SENCOs and increase their focus on classroom practice.     

Excluding Primary School Children – The Outcomes Six Years On

This article reports and discusses a study which followed up, through case records, 726 children excluded permanently, indefinitely or for fixed–term periods in 1993/4 in 10 LEAs. The outcomes at secondary level in 1998/9 were found to be moderately poor with the problems intensifying for half the sample. Forty six per cent had further primary school exclusions and 36 per cent received exclusions in their secondary education. Looked–after children and those with special educational needs fared worse and achieved less. Case studies showed the kinds of commitment and support that can work even with very difficult cases.     

Dependence or independence in education? two cases from post-colonial South-East Asia

This paper seeks to question how far the dependency theory is universally valid and whether it can be applied to all sections of the education system. The first part examines some of the arguments in favour of continuing dependency and points out weaknesses in the theory especially in relation to educational dependency. It argues that the complex interrelationships of education and society often far outweigh any lasting vestiges of colonial involvement from outside. The second part of the paper seeks to test the validity of educational dependency. By examining one country that avoided any formal colonial control, Thailand, and another that was colonised by the British for over 170 years, Malaysia, it shows that the internal political framework of a society can far outweigh any attempts at external control; and that where external involvement is sought it is often done willingly and not necessarily on terms of subservience. Educational borrowing can be as much on the terms of the recipient as it is of the donor. The surprising thing is not the levels of dependence, but the levels of independence in both societies.     

Policy learning and innovation theory: an interactive and co-evolving process

This paper explores links between the development of innovation theory since the late 1970s, and the evolution of innovation policy ideas, primarily in the 1990s. The argument is that there is a close connection between theory and policy, so that theory and policy learning can be seen as an integrated, co-evolving and interactive process. We analyse the theory-policy learning link in terms of two phases. We suggest that the complex economic crisis of the 1970s created an opening for rival analyses of events. During the 1980s, the development of evolutionary theories (pioneered by Nelson and Winter) and of empirically-based theories of the innovation process (pioneered by Nathan Rosenberg) created a framework in which policy agencies could consider heterodox ideas concerning objectives and instruments of public policy. By the early 1990s policy-makers, particularly in Europe, came to see RTD and innovation policies not just as important arenas of action in themselves, but as instruments towards more wide ranging policy objectives. The policy agencies involved, though hierarchical, were characterised by relatively open structures that permitted a degree of intellectual diversity: so organisations like the OECD and the European Commission played a central role, whereas the World Bank, for example, did not. Increasing policy interest stimulated a second phase of research in the 1990s, sponsored both nationally and by various EU programmes, in which expanding the innovation-oriented knowledge base became a significant objective for policy-makers. The paper argues that the theory-policy link has been central to the intellectual development of this field, which would have been impossible within the constraints of existing disciplinary structures and university funding systems. At the same time the analytical achievements have permitted a wide expansion in the conceptualization of policy targets and in the design of instruments available to policy-makers. In a sense, this is itself an evolutionary story: of a crisis and a conjunctural niche that permitted the creation and (so far) survival of a set of diverse and certainly non-conventional ideas.
