A person’s size and gender can play a role in how they sweat and where they sweat. women typically sweat less than men. women have fewer sweat glands but they also have less muscle mass so they produce less heat.
To measure sweat rate in the body
To prevent dehydration, marathoners, triathletes and other athletes find their sweat rate so they know how much water they need to drink during an activity and measuring the sweat rate.
Weigh the body on a set of scales.
Do an intensive physical activity for an hour like running ideally in the condition in which they will compete. The amount of weight lost measured as sweat rate.
One pound (0.45 kilograms) of weight loss equals 16 ounces (0.47 liters) of sweat loss. This rate can vary somewhat based on the intensity of the activity, humidity, blood sugar rate and other factors. Considering the amount of water the athlete needs to drink in that hour of activity increasingly.
