Creatine kinase, encoded by the CKM gene, is an enzyme which influences the energy systems used in your cells.  Your FitnessGenes result tells you whether you carry a CKM genotype that is found more commonly in endurance or strength athletes.  CKM levels are also related to the ability to process oxygen which is important for speed and endurance.
