Effect of Toe Clips during Bicycle Ergometry on [Vdot]O2 max

Abstract

Previous investigators have yielded conflicting results in testing the hypothesis that the use of toe clips during bicycle ergometry produces a higher maximal oxygen uptake ([Vdot]O ₂ max) than testing without toe clips. Eight men, four competitive cyclists and four competitive distance runners volunteered to participate in three randomized [Vdot]O ₂ max tests: 1) a treadmill running lest, 2) a bicycle ergometer test using standard toe clips, and 3) a test on the same ergometer without toe clips. The highest mean [Vdot]O ₂ max was observed in the treadmill condition as expected. However, no statistically significant difference in mean [Vdot]O ₂ max or performance time was observed between the toe-clip and no toe-clip conditions. Based on these results, the research hypothesis was rejected and no favorable physiological effect may be attributed to the use of toe clips.     

Response Timing Accuracy of Long-Distance Movements

Abstract

The purpose of the study was to compare the effectiveness of the Red Cross and Silvia methods of teaching beginning swimming. College women (N = 76), who were beginners in swimming, served as subjects. Pretests indicated no differences among the four classes prior to instruction. Reliability coefficients of the post-tests for distance and survival time (test-retest method) ranged from .70 to .98. ANOVA procedures utilizing front crawl distance, back crawl distance, survival time, and length of time required to pass the Red Cross combined tests as dependent variables resulted in superiority of the Silvia method over the Red Cross method in each analysis.     

Optimization of the felge on parallel bars

The felge, or undersomersault, on parallel bars has become an important skill in men's artistic gymnastics as it forms the basis of many complex variations. To receive no deductions from the judges, the felge must be performed without demonstrating the use of strength to achieve the final handstand position. Two male gymnasts each performed nine trials of the felge from handstand to handstand while data were recorded using an automatic motion capture system. The highest and lowest scoring trials of each gymnast, as determined by four international judges, were chosen for further analysis. The technique used by each gymnast was optimized using a computer simulation model so that the final handstand position could be achieved with straight arms. Two separate optimizations found different techniques identified in the coaching literature that are used by gymnasts. Optimum simulations resulted in improved performances through a combination of increased vertical velocity and height of the mass centre at release. Although the optimum technique found close to the gymnasts' own technique was more demanding in terms of the strength required, it offered the potential for more consistent performance and future developments in skill complexity.     

Health-inclusive higher education: listening to students with disabilities or chronic illnesses

This paper reports on a small-scale project undertaken with tertiary students who identified as having an impairment either at enrolment or by registering with the university's Disability Support Unit (DSU). The aim of the study was to explore with these students ways in which the university was currently meeting their academic support needs and the ways in which these needs might be better met. Consistent with the definition of disability within the Australian Disability Discrimination Act, it became apparent that a significant number of students who identified with that definition, or sought help from disability services, also presented with needs arising from chronic illness. The majority of participants cited an emotional or psychological illness, rather than a physical, intellectual or sensory one, as a possible precursor to difficulties in engagement with the university. We conclude by considering whether commonly used institutional categories are apposite to an understanding of the ways in which students perceive themselves and, importantly, their engagement with the university and success within it.     

Parental Participation in Paired Reading: a controlled study

Abstract A double‐blind controlled study of the effects of Paired Reading was carried out with 33 failing readers and their parents. The children were aged 8 to 11 and had reading delays of at least 18 months. After a mean time of 7.6 hours of Paired Reading at home, spread over six weeks, the children made gains of 2.43 months for reading accuracy and 4.36 months for reading comprehension compared with a control group which experienced respective gains of 0.81 months and 1.69 months. The differences were statistically significant for accuracy but not for comprehension. The conclusions of previous Paired Reading studies are discussed in the light of these results and suggestions are made for the evaluation of future, similar projects.     

The Virtual Field Station (VFS): using a virtual reality environment for ecological fieldwork in A-Level biological studies—Case Study 3

Case studies are one way of producing the evidential base necessary for ICT to become embedded in everyday teaching and learning. Such case studies are vital for the purposes of generalisation. Also, teacher generated case-studies have the benefit of being research that is done by teachers in conjunction with Higher Education support and mediation, as opposed to research being done to teachers by Higher Education. One such teacher-generated case study at the cutting edge of ICT researches the effectiveness of a Virtual Field Station for the teaching of an A Level biology topic. The subject was the exotic one of the Mediterranean sea turtle. Student fieldwork involving these fascinating creatures is desirable but difficult, as the sea turtle's habitat is the archipelago of the Aegean Sea. The paper argues that a Virtual Field Centre is an effective substitute for actuality in terms of the development of student knowledge and understanding for examination purposes. As such, it is an innovative development that sits at the forefront of an area of Science Education that is rapidly developing, ie ICT-mediated teaching and learning.
