| Food |
Participants consume the test foods 1 in a hot environment. After 30 minutes of sitting rest, in a hot environment, participants perform cycling exercise at 60% of their maximal oxygen uptake in a hot environment until their core temperature reach at 38 degrees Celsius or perform cycling exercise up to 45 min. The primary and secondary outcomes are evaluated over the experimental period.
