A Comparison of Autonomic Nervous System Activity between Physically Trained and Untrained Individuals

Abstract

The study is concerned with the comparison of autonomic nervous system (ANS) activity between highly trained collegiate track and field athletes and untrained individuals. An ANS test battery consisting of six individual measures of autonomic activity was used: (a) sublingual temperature, (b) salivary output, (c) volar skin resistance, (d) palmar skin resistance, (e) diastolic blood pressure, and (f) heart period. One group of athletes, track runners, were found to have a mean autonomic balance score significantly higher (at the .02 level) than the norm group of college students. The autonomic scores of field event athletes, however, were not significantly different from the norm. An analysis of the type of ANS activity demonstrated by the runners showed a dominance by the parasympathetic as compared to a mixed pattern demonstrated by the normative sample. It was concluded that highly trained track runners demonstrated a significantly higher autonomic balance score than did normal college students, and that their resting autonomic pattern was predominantly parasympathetic. There was evidence to indicate that equality of performance in the running events in track, and possibly other athletic events, may be partially predictable from autonomic balance scores.

Introducing a fifth pedagogy: experience‐based strategies for facilitating learning in natural environments

Educators have identified four categories of ‘productive pedagogies’ that are considered to lead to authentic student engagement and learning in the classroom. This study was designed to explore and extend these pedagogies in the context of learning in natural environments, in particular, through the programmes of Queensland environmental education centres. In‐depth interview and observation data were collected from students, classroom teachers and centre teachers who had participated in 12 environmental education programmes across Queensland, in order to identify the strategies that are most effective in facilitating learning in the natural environment. A fifth productive pedagogy category, ‘experience‐based learning’, is proposed. Experience‐based learning is particularly important in addressing students’ environmental attitudes and actions. The implications for the delivery of environmental education programmes both within and outside the classroom are discussed.
