Other health related effects of exercise include reductions in bone density loss and in the rate of occurrence of stroke, and improvements in the functioning of the immune system, management of diabetes, and the control of joint pain in arthritis. In short, being fit generally indicates a healthy condition. Being unfit makes you susceptible to various diseases. Aerobic fitness indicates the capability to perform prolonged work.
Fit people can work or play for prolonged periods without fatigue.
Unfit people are limited in what they can do. The UFT is a new, patented, method to measure aerobic fitness. It provides, for the first time, a quick and easy way to predict a very important health and fitness indicator - maximal oxygen uptake. The UFT consists of stepping on a stool for 30 seconds at a comfortable rate, while the pulse is monitored. Certain pulse characteristics, plus age, sex, and weight are used to calculate your fitness.
