Freezing point of muscle
What exactly is the freezing point of muscle? I know it's not liquid so does that mean it's already frozen. At what temperature does muscle turn to hard brittle fibers that shatter when stretched beyond their frozen limits? I think I hit that temperature this morning during my 2 mile run for the APFT. After I ran I got into my car to go home and every muscle in my body ached. Even the muscles I hadn't used were killing me. As I rotated the wheel to make a left turn my radial muscles cringed in protest as their frozen fibers were flexed. Now, my muscles are all sore. Maybe I need to loosen and warm them up again with a jog then get a massage... That could work. Basically, frozen muscles aren't fun. Nope...
1. The mean depression of the freezing point for the resting muscle
of the bull frog was found to be 0.42°C.
2. The mean depression of the freezing point for the completely
fatigued muscle of the bull frog was found to be 0.57°C.
3. The mean difference in freezing points for resting and fatigued
muscle is 0.15°C. This is equivalent to the depression of the freezing
point of an 0.08 M solution of a non-electrolyte.
4. On account of the magnitude of the increase in the depression of
the freezing point as a result of fatigue, it is concluded that the in-
creased imbibition of fatigued muscle is caused entirely by the in-
crease in concentration of dissolved substances, ions and molecules,
within the muscle.
5. The freezing point of muscle fatigued in the body with circulation
intact is identical to that of the resting muscle of the same individual.
Oh and look what I found:
