Durin a race the body temperature of a runner increases?

During a race, a runner's body temperature increases due to the metabolic heat generated by muscle activity. As the intensity of exercise rises, the body works harder to produce energy, leading to elevated heat production. To regulate this temperature, the body activates mechanisms such as sweating and increased blood flow to the skin, facilitating heat dissipation. Maintaining an optimal body temperature is crucial for performance and preventing overheating.
