Are you worried that you’re overtraining? InsideTracker can help you find out by measuring your blood level of Creatine Kinase, an enzyme that is found in muscle cells. When your muscles are healthy and uninjured, there is very little CK in your blood. When muscles cells rupture from over-exertion, CK spills into your blood. Symptoms of high levels of CK include muscle pain, cramps, and fatigue. As levels of Creatine Kinase increase, the amount of muscle cramping and damage rises, the athlete feels fatigued faster, and the risk of injury increases. Excess Creatine Kinase also slows recovery from training and from injuries. InsideTracker will tell you what your optimal Creatine Kinase levels should be based on your age, gender, ethnicity, activity level, and lifestyle. To repair the muscle damage indicated by high CK levels, you need to consume more protein, from foods such as meats or beans, and to modify your exercise program to allow time for recovery.show more
