Reasons for Fatigue & Muscle Pain

Muscle pain can be the cause of many things, but muscle pain caused by fatigue is likely due to over working the muscles. When muscles undergo intense physical activity, fatigue is the almost always the aftermath.

Cause

• Muscles tear when they are exercised and rebuild themselves afterward. The body has to focus on rebuilding the muscles and directs more energy to that area much like when you are sick, your body has to fight germs and you experience fatigue due to fever.

Overexercising

• When working out, you should never go past the point when you can't lift three-fourths of the weight you normally lift at the beginning of your workout. Going past that point tears your muscles to a degree that you will feel fatigued for the next few days.

Inactivity

• If you workout after a long period of inactivity, it will feel like a "shock" to your muscles, which became used to not working out. The body has to adapt in very little time to this sudden change and you will feel fatigue and muscle pain due to it.

Good Fatigue

• Feeling sore is not a bad sign; it means that you have done an effective workout. If you feel sore to the point that it hurts to do regular everyday activities, that is bad fatigue.

Calcium

• When you exercise, the calcium channels leak and force the muscles to contract. This causes soreness but not to a significant degree.
