Speed running, also known as sprinting, is characterized by a runner's ability to cover short distances as fast as possible. On the other hand, fatigue resistant running -- also known as long distance running -- is a style of running in which a runner maintains a moderate speed over a long period of time. The ratio of slow-twitch to fast-twitch skeletal muscle fibers in an athlete's body can help determine if he is better suited for a sprinting style or a long distance style of running.
In 1930, Gerard Berchet, a researcher working for Dupont, began investigating the polymerization of 6-aminocaproic acid. By 1935, Berchet completed his work, which resulted in the synthesis of polyamide 66, also known as nylon. Today, it's difficult to imagine what the world would be like without nylon. From mountaineering equipment to Christmas decorations, nylon has become one of the most widely-used polymers. In some applications, such as in designing nylon mountaineering rope, it's important to know the fatigue strength of the polymer.

Fatigue occurs when a material is subjected to alternating, or cyclic, stress over a long period of time. This repeated motion weakens the material in a similar manner to when you repeatedly exercise a particular muscle in your body; you become tired and unable to continue.

Fatigue and stress ratio are two key concepts used in the fatigue testing of materials.

Muscles are the tissues in the body that push and pull bones and joints. Muscles are composed of smooth, cardiac and skeletal muscle fibers and utilize energy to perform physical tasks. Muscles fatigue over time after they perform work. They then require time to recover before they can act in full force once again. An accelerometer measures the acceleration of an object, and can be used to measure the acceleration of body parts as well. Therefore, it can be used to measure muscle fatigue.
