Causes Dizziness, Cramps And Fainting After Hard Work?

Explain why when we work hard or do sports there will be r n1. dizziness r n2. cramps r n3. fainting r n4. Sweating r n This is related to the phase of muscle relaxation r nFrom starch + h2o u0026gt; glucos + o2 u0026gt; energy ATp + co2 + lactic acid. r nPlease explain with the above relationship one by one why this incident happened.

1 Answer:


From the information you have conveyed, in general muscle contraction and relaxation depends on the activity of the Ca pump and also the activity of ATP (adenosine triphosphate). When Ca and ATP are released, muscle contractions will run according to their function and purpose.

Meanwhile, when calcium re-enters the sarcoplasmic reticulum, and ATP starts to decrease, the relaxation phase will take place,

What affects the function of ATP in muscle contraction are:

1. oxygen

2, glucose in the glycolysis cycle

During the muscle contraction process, the muscle contraction process using ATP energy will decrease, causing the formation of lactic acid. This excessive formation of lactic acid will cause complaints of fatigue and pain or discomfort in the muscles.

Thus, if the energy reserves cannot be processed into energy through the glycolysis process, the complaints that often occur are: dizziness, cramps, fainting, cold sweat, which is a form of compensation for muscle fatigue, the high need for glycolysis that cannot be met, especially in Krebs cycle.

That is the information we can convey.
