While final core body temperature was significantly higher on the natural than synthetic grass (38.4 \u00b0C [0.3 \u00b0C] vs 38.2 \u00b0C [0.4 \u00b0C]),\u00a0there were no significant differences in delta core temperature, as well as heart rate, thermal comfort, or RPE. <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> Higher skin temperatures, thermal sensation, and sweat rates suggest that exercising on synthetic grass in hot conditions may increase some markers of heat strain during exercise.
