hi guys,
Fitness has been defined in relation to a concept called physical work capacity, or how much work the body can do. A person's fitness can be determined in a laboratory by looking at how much energy they can produce on a cycle ergometer when cycling at a specific heart rate, or on an athletic track by looking at how far they can run in a set time. Fitness can also be understood in relation to a number of components including endurance, flexibility, strength and power. You need to be fit to play many sports, including football, hockey and tennis.
Health, on the other hand, is a broader concept that includes being free from and resilient to disease, mental and spiritual wellbeing, and the quality of our social relationships. Normally, being fit and being healthy go hand in hand, but this isn't always the case. For example, you can be very fit, through playing football for example, but suffer a major health problem such as alcoholism.
Understanding the difference between fitness and health is important because the level of exercise you need to be healthy is less than that needed to get and keep you fit.
