The converse can also be true. The client in either case must be encouraged to proceed slowly as the different systems catch up to each other in their conditioning levels. Heartrate Variables Many things can affect the exerciser s heartrate response. Some participants feel that the amount of sweat they produce determines the intensity of the workout. Sweat glands are not pipelines to fat stores.
Sweat is simply the body s cooling system, much like a home or car air-conditioning system.
The heartrate will increase as the body cools itself because the cooling mechanism needs increased blood flow. Working out in a pool with warmer than normal water, a warm air temperature, high humidity, direct sunlight, and little air circulation or working out in a pool wearing a complete unitard or a swimcap will increase the heartrate. But this increase will not correlate to an increase in caloric or oxygen consumption. The heart is simply trying to help the body dissipate heat. The result would be additional heart stress, rather than heart training.
