Hypothetically, if the threshold is normally -60mV, but now we have too much calcium on board, our threshold is now -50mv. That is a difference of 40mV that the cell has to account for in order to depolarize. In skeletal muscle, this can cause weakness, fatigue, etc. Too little calcium will cause the threshold to become more negative (gets closer to the resting membrane potential).
OK, this is probably going to come with you laughing at me... Once in a while I wake up with the back of my head sweating, and it`s more common when I take a nap during the day.
In many cases, not sweating enough during a workout just means that you have to exercise longer and more intensely. Sweating is your body's way of regulating its temperature. Your body excretes fluids through your sweat glands when your body temperature increases due to hot weather, exercise and nervousness.Sweating is, therefore, a healthy and necessary bodily mechanism.If you're not sweating during your workouts, it may be due to a variety of factors.our body excretes fluids through your sweat glands when your body temperature increases due to hot weather, exercise and nervousness.
