Explanation:
For the purpose of determining one's state physical fitness, body composition is often used as a contributing indicator and is measured via the ratio between fat tissue and muscle tissue. Â Maintaining a higher level of muscle than fatty tissue keeps the metabolism functioning at a higher level because muscle burns more energy and fat. Â Ironically, muscle tissue can even burn fat as a fuel source. Â Therefore, the presence of more of muscle tissue is indicative of a higher level of physical fitness. Â
The density of muscle tissue is higher than that of fat tissue. Â Therefore, a person with a significantly higher ratio of muscle to fatty tissue, may actually weight more than another person of equal size whose ratio is of fat to muscle is higher.
As a general rule, one would expect that the individual with a greater amount of muscle tissue is in better physical condition. Â However, it is important to remember that moderation, even in the amount of muscle tissue, is preferred. Â The human body needs fat, as it is an essential building block for the nervous system, provides insulation, acts as a shock absorber for organs, and is an excellent source of fuel.
