Summary

A randomised, crossover, counterbalanced repeated measures study will be conducted to examine the effect of acute heat exposure on rate of change in blood glucose concentration during 40 minutes of moderate-intensity exercise and for 30 minutes after exercise. Participants will complete two experimental conditions during two separate laboratory visits, with the order of conditions randomised. One condition will be a temperate condition of 20°C with 50% relative humidity (Temperate), the other will be 40°C with 50% relative humidity (Heat). Visits will be identical, including time of day, except for the condition. Visits will be separated by 24h. Testing will take place in the laboratories of the Research Institute for Sport and Exercise Sciences at Liverpool John Moores University.
