Runners needed

UCT/ MRC Research Unit for Exercise Science and SISSA is investigating exercise-induced heatstroke (EIH).


UCT/ MRC Research Unit for Exercise Science and SISSA is investigating exercise-induced heatstroke (EIH).

Looking for

  • Runners (capable of running 10km under 65 minutes) eager to aid in discovering the causes of EIH.
  • Runners (capable of running 10km under 65 minutes), who have previously experienced EIH (confirmed by a doctor) and who are willing to find out more about its causes.


  • Regular runner (3x times a week): 18-45 years of age
  • Be able to visit the Sports Science Institute of South Africa 5 times
  • Testing includes:
    1) medical examination and questionnaire
    2) 15ml x blood and urine samples per visit
    3) 4 x 10km time trials in varying environmental and nutritional conditions on a treadmill in the environmental chamber
    4) 4 x ingestion of disposable temperature monitoring pills
    5) genetic testing (heatstroke patients only)
    6) 1 x muscle biopsy (if willing, both groups)

Benefits to recruits

  • General medical examination and anthropometric measurements by a qualified doctor.
  • Non-EIH individuals gain insight into various aspects of their bodies’ physiological responses to exercise i.e. thermoregulatory, immunological and other, which may assist in optimising future training strategies.
  • EIH individuals will receive medical, physiological and genetic tests, which aim at explaining the reasons for their previous susceptibility to EIH and assessing their current state of heat tolerance.
  • Muscle fibre analysis, including fibre type determination (if muscle biopsy taken)

Sports Science Institute of South Africa, Cape Town
