Figure 2-4. Length tension curve of an FCT fiber.
2-27. TEMPERATURE AND TENSION
a. The degree of elasticity (stretchability) of an FCT is more or less proportional
to its temperature. The cooler it is, the less stretchable and the more subject to damage
it is. On the other hand, as the fiber becomes warmer, its stretchability and resistance
to damage increase.
b. This characteristic is the basis of warm-up exercises before participating in
strenuous activities such as sports. By exercising to the point of sensible perspiration
(para 2-7c), the body, temperature
to the desired level.
At this level, the FCT
are able to stretch and withstand the various forces applied to them.
