In the late 1960s, aerobics emerged as a system of organized exercise developed by Dr. Kenneth Cooper, who was interested in using exercise to condition your cardiovascular system, according to “We Are the Champions: The Politics of Sports and Popular Music” by Ken McLeod. With the introduction of dance moves and music in the 1970s, aerobics became a popular form of exercise primarily among women. Since then, many aerobic variants, such as step aerobics, dancing and spinning, have taken off. Because aerobics is designed for cardiovascular fitness and will elevate your body temperature, you’ll sweat to cool off.
Aerobics Regimen
An aerobics class can provide a rigorous cardiovascular workout. A mid-tempo class may run anywhere from 20 to 30 minutes and raise your heart rate to between 130 and 140 beats per minute. If you’re participating in a high-impact class, you can expect your heart rate to increase to anywhere from 135 to 160 bpm. Even a low-impact class in which exercises -- lunges, squats, step touches and marching -- are performed close to the ground will get your heart pumping and your body covered with sweat.
Thermoregulation
When you exercise in an aerobics class, your muscles generate more heat. To maintain your body temperature within safe limits – 98.6 degrees F – this excess heat must be dispersed. If your temperature rises above these limits, you’ll overheat, which wreaks havoc on normal physiological functions. Your body’s most effective way to remove heat is sweat. Your capillaries carry water to the surface of your skin. Once the water seeps out of your pores, it evaporates and cools your body. You lose about 600 kcal of energy for every liter of sweat that evaporates, according to “The Complete Guide to Sports Nutrition” by Anita Bean.
Amount of Sweat
How much you sweat depends on how hard you’re exercising in the aerobics class as well as the heat and humidity of your environment. In general, you’ll lose about a liter of fluid for every hour of exercise. If you’re exercising in a hot and humid place, you can lose twice that amount, according to Bean. The amount you sweat also depends on your genetics. Some people just don’t sweat as much as others. A smaller thinner body produces less sweat, which is why women tend to sweat less than men. In addition, if you’re fit, your body’s thermoregulatory system is typically in better working order and you’ll tend to sweat more.
Dehydration
Hydrate before, during and after you perform aerobics. If you lose too much fluid, you risk dehydration. Because there’s less fluid in your blood, your heart has to pump that much more blood to your muscles to sustain your performance. This condition takes a hefty toll on your lungs, heart and circulatory system. Losing just 2 percent of your weight in fluid during an aerobics class can decrease your maximal aerobic capacity by as much as 20 percent, according to Bean. When you lose 4 percent of your weight in water, you may experience such symptoms as vomiting, diarrhea and nausea. The more fluid you lose, the more serious the effects of dehydration. You’ll also sweat less because less blood is being transported to your skin.
