Jim Cotter

Steering Group

Professor Jim Cotter is an exercise and environmental physiologist, working in the School of Physical Education, Sport and Exercise Sciences at the University of Otago.

His research interests lie in:

  • Acute and adaptive effects of the discrete stressors that comprise exercise and natural environments;
  • Heat stress and dehydration
  • Cerebrovascular health
  • Behaviour in stress physiology

Jim’s recent and current focus is on the extent and mechanisms by which:

  • different forms and patterns of heat stress affect human tolerance and adaptation;
  • physical activity and environmental stressors affect the human brain; and
  • behaviour and chronic illnesses modulate the acute and adaptive effects of heat stress.
  • Heat, humidity and dehydration act alone and together on work tolerance.


  • Exercise physiology
  • Environmental physiology
