Heart rate prescribed walking training improves cardiorespiratory fitness but not glycaemic control in people with type 2 diabetes

Abstract

In this study, we examined the effects of a supervised, heart rate intensity prescribed walking training programme on cardiorespiratory fitness and glycaemic control in people with type 2 diabetes mellitus. After receiving local ethics approval, 27 individuals (21 males, 6 females) with type 2 diabetes were randomly assigned to an experimental (“walking”) or control group. Participants completed a Balke-Ware test to determine peak heart rate, peak oxygen consumption ([Vdot]O_2peak), and peak gradient. The walking group then completed a 7-week (four sessions a week) supervised, heart rate prescribed walking training programme, whereas the control group continued daily life. After training, participants completed another Balke-Ware test. Fasting blood glucose and glycosylated haemoglobin were measured at rest. The results showed that walking training elicited 80% (s = 2) of peak heart rate and a rating of perceived exertion of 11 (s = 1). Peak heart rate and [Vdot]O_2peak were higher in the walking than in the control group after training (P < 0.05). Based on the peak gradient before training, the respiratory exchange ratio was significantly lower (P < 0.05) and there was a strong trend for [Vdot]O₂ (P = 0.09) and heart rate (P = 0.09) to be lower after training at the same gradient in the walking compared with the control group. These improvements increased walking peak gradient by 5 min (s = 4 min) compared with the control (P < 0.05). There was no change in fasting blood glucose or glycosylated haemoglobin after training. Despite no change in glycaemic control, heart rate prescribed walking improved peak and sub-maximal cardiorespiratory responses. The beneficial adaptations support the use of heart rate monitoring during walking in people with type 2 diabetes mellitus.     

Personal Backgrounds of Effective Teaching

Planning time for giving students effective feedback is an important and challenging aspect of the teaching and learning process. In our article we describe and analyze how we engage students as partners in providing formative feedback in time for students to modify their own thinking or behavior to improve learning. We have found ways to provide formative feedback more frequently and to involve students in providing effective formative feedback to each other. The four techniques we describe are the following: a) three-color group quiz with feedback on product, process, and progress; b) midterm student conferencing; c) shared revision of student generated questions and statements; and d) timely feedback using collaborative assignment blogs. These techniques give feedback in time for revisions to occur, provide scaffolding for learners, inform instruction, and most importantly, involve students as partners in assessment. These pedagogical strategies show that the resulting benefits of improved instruction, enhanced student learning, and better student products are worth the time and effort and contribute to a productive classroom climate where the focus is on learning more than on grading. Formative feedback involving students as partners is a key strategy to enhance the teaching and learning process.     

Student teachers in school practice: an analysis of learning opportunities

Abstract

Over the past decade, educational policy in Britain, as in other industrial nations, has been increasingly driven by the concern that higher education should serve the needs of the economy more effectively. The report Highly Qualified People: supply and demand reflects this concern and attempts to establish from employers Britain's likely requirement, in the 1990s, for such expensively educated labour. Though the report concluded that Britain needed more graduates over the next few years, closer scrutiny of its data suggests a very different conclusion ‐ not that Britain needs more graduates to prosper, but rather that Britain needs first to prosper before it is likely to want the graduates it already produces.

     

TRAINING OLDER AND YOUNGER ADULTS TO USE SOFTWARE

Forty‐six subjects (22 young, 24 old) received three training sessions with software (Borland's “Sidekick"). Each session lasted a maximum of S h. The fourth session was a test. Subjects were randomly assigned to two learning environments, partnered or individual, and half were given a computer “jargon” sheet before training. All instructions were written, learning was self‐paced, and tasks were formulated according to discovery‐method guidelines. Attitudes toward computers were measured before Session 1 and on completion of Session 3. The results showed that older adults took twice as long as younger ones but achieved nearly equal performance levels, exceeding young adults in one condition but falling slightly below them in others. Older adults requested help two to three times as frequently. Session 3 attitude scores were positively correlated with the mark achieved on the final test, and changes in attitudes were related to training conditions.     

The role and the training of teacher-counsellors

The example of teachers not seeking counselling was used. Some reasons for this situation were given as well as one possible way to change it by providing early information and training during the students' regular studies. My hope is that if teachers have the necessary information, abilities and positive experiences, when they have problems, it should be easier for them to use counsellors than it is for other today.Teachers were used as an example of how one group could be encounraged to make use of counsellors. However, similar strategies could be used with other groups whose jobs involve high personal stress (for example social workers, medical doctors etc.). The example of teachers was also used to show how change can be introduced within a system. Here it might be useful to develop the ability to work with a counsellor during the regular education, so that it becomes part of their understanding of their professional role.
