What percentage of the heat of locomotion is dissipated through sweating?

The correct answer indicates that 70% of the heat generated during locomotion is dissipated through sweating. This process is crucial for horses, especially during exertion, as they do not have as many sweat glands as humans, but those they do have are highly efficient in regulating body temperature.

As a horse engages in physical activity, muscle contractions generate significant heat. To prevent overheating, the horse's body utilizes sweating as a means of thermoregulation. The evaporation of sweat from the skin surface removes this excess heat from the body, enabling the horse to continue performing optimally without succumbing to heat stress.

Understanding this percentage highlights the importance of proper hydration and management during activities for horses, as excessive sweating can lead to dehydration and other health issues. Thus, this knowledge is essential for horse owners and caretakers to ensure the wellbeing of their equine companions during training and competition.
