Relationship between laboratory-measured variables and heart rate during an ultra-endurance triathlon

The aim of the present study was to examine the relationship between the performance heart rate during an ultra-endurance triathlon and the heart rate corresponding to several demarcation points measured during laboratory-based progressive cycle ergometry and treadmill running. Less than one month before an ultra-endurance triathlon, 21 well-trained ultra-endurance triathletes (mean +/- s: age 35 +/- 6 years, height 1.77 +/- 0.05 m, mass 74.0 +/- 6.9 kg, = 4.75 +/- 0.42 l x min(-1)) performed progressive exercise tests of cycle ergometry and treadmill running for the determination of peak oxygen uptake (VO2peak), heart rate corresponding to the first and second ventilatory thresholds, as well as the heart rate deflection point. Portable telemetry units recorded heart rate at 60 s increments throughout the ultra-endurance triathlon. Heart rate during the cycle and run phases of the ultra-endurance triathlon (148 +/- 9 and 143 +/- 13 beats x min(-1) respectively) were significantly (P < 0.05) less than the second ventilatory thresholds (160 +/- 13 and 165 +/- 14 beats x min(-1) respectively) and heart rate deflection points (170 +/- 13 and 179 +/- 9 beats x min(-1) respectively). However, mean heart rate during the cycle and run phases of the ultra-endurance triathlon were significantly related to (r = 0.76 and 0.66; P < 0.01), and not significantly different from, the first ventilatory thresholds (146 +/- 12 and 148 +/- 15 beats x min(-1) respectively). Furthermore, the difference between heart rate during the cycle phase of the ultra-endurance triathlon and heart rate at the first ventilatory threshold was related to marathon run time (r = 0.61; P < 0.01) and overall ultra-endurance triathlon time (r = 0.45; P < 0.05). The results suggest that triathletes perform the cycle and run phases of the ultra-endurance triathlon at an exercise intensity near their first ventilatory threshold.     

Home birth: the wave of the future?

A childbirth educator expresses frustration with a medical system that does not work for women or for many maternity care providers. She suggests out-of-hospital birth as an alternative. This column explores the safety of home birth, women's experiences of home birth, and the issues related to home birth once again being the standard. Childbirth educators are encouraged to present home birth as a viable choice.     

Inclusion of students with emotional and behavioural disorders in general education settings: a scoping review of research in the US

ABSTRACT

Inclusion of students with disabilities in general education settings has been an international focus for over two decades. In the US, federal laws [e.g. Individuals with Disabilities Education Improvement Act (IDEIA). 2004. H.R. 1350, 108th Congress] mandate access to the general education curriculum for all students, including those with disabilities. These mandates codify a philosophical orientation of least restrictive environment, within a free appropriate public education, while explicitly requiring evidence-based practices. The policies support and protect inclusive practices for individuals with emotional and behavioural disabilities, yet the state of the empirical literature is unknown. A review is needed to provide an overview of the research and reveal the breadth of the literature. To this end, scoping review methodology was used to map the state of the literature. This particular approach is recommended for topics with myriad and complex definitions and issues, as is the case with inclusive education. Results map six themes (professional and student experience, strategy effectiveness, policy and programmes, perception of influencing factors, teacher training, teacher knowledge) and reveal several gaps in the literature. Recommendations are made for systematic review, meta-analyses, and individual studies to address the gaps in the literature.     

CURRICULUM AND IDEOLOGY: INDOCTRINATION AS AN INAPPROPRIATE APPROACH TO CONSERVATIVE JEWISH EDUCATION

Education is a dynamic discipline. Dynamic because an educational system does not stand on its own, apart from the social structure of which it is an extension. It must be steeped with its culture's moral and sociological beliefs in order to ensure the survival and growth of that particular culture through each new generation.     

‘RE teachers do get drunk you know’: becoming a religious education teacher in the twenty-first century

In terms of the attention that they have attracted from researchers, and in comparison with teachers of other subjects, religious education specialists would seem to be a neglected and marginalized group. This paper looks at some of the reasons why this might be and also describes a study that is using a life history approach to explore what it is like to be a religious education teacher at the turn of the millennium.
