Background

Jim Cotter is a Professor at the School of Physical Education (Lecturer 2001-6). Jim obtained his BSc (1987, Physiology), BPhEd (1988, Distinction) and MPhEd (1992, Distinction) at Otago before heading to Australia to complete a PhD in Environmental Physiology at the University of Wollongong (1998). Following a lectureship there in 1997, he worked as a Research Scientist in the Australian Defence Science & Technology Organisation for three years (1998-2001), investigating human tolerance and adaptation under adverse ergonomic and environmental conditions. Now at The University of Otago, he researches, teaches and provides service in these fields in both health and performance contexts.

Research

Jim has three interrelated research interests

  1. Which exercise stressors are important for health- and performance-related fitness adaptations; especially the separate and interactive roles and dose:response relations of different forms of stress (e.g., heat, hypoxia, hypohydration).
  2. Such stressors are also environmental stressors, so to what extent can stressful environments supplement or replace those of exercise conditioning.
  3. Thermoregulatory, cerebrovascular and cardiovascular control and determinants of tolerance under heat, hydrative or orthostatic stress, and subsequently the effects of physical and physiological strategies to reduce physiological strain and maximise tolerance.

Techniques used in the projects include measurement of body temperature, on-line sweat rate and composition, perfusion of the whole-body, brain and isolated limbs, blood volume and composition, respiratory function, perceived status, work performance, blood glucose, and plasma concentrations of cytokines, fluid-regulatory and stress hormones and oxidative stress markers. Funding for projects has been obtained from Lottery Health NZ, IOC Medical Commission, ITU, FINA, NZ Academy of Sport, SPARC, Otago Medical Research Foundation, NZ Rugby Union, Otago University, and industry.
