Molecules in cold objects move slower than that of warm objects (Burdge, 2014). It should then follow that a cold muscle will have less strength than a warm muscle. In order to better understand this, it is necessary to understand the physiological process. A muscle is stimulated by an action potential (Kincaid, 1999). An action potential is affected by temperature because molecules are affected by temperature (Buzantu, 2009). The contraction of a muscle occurs when calcium ions allow myosin to bind with actin in the sarcomere (Fox, 2009). Since calcium ions are atoms they too suffer from the effects of temperature. The strength of a muscle contraction is based on two things, the number of motor units recruited or temporal summation (Taylor,
