Rocky Moutain ACSM conference - homocysteine

I was fortunate enough to attend the Rocky Mountain ACSM conference last weekend. During the two weekend days, I learned about nutrition, exercise, muscle mitochondria, exercise adherence, and homocysteine. Today I want to relay some information about the workshop that involved homocysteine. Homocysteine is an intermediate compound that can turn into an amino acid called methionine or cysteine. This process requires vitamin B12 or B6 and folate. Regulating homocysteine level is importance because high levels of homocysteine is indicative of endothelial lining, such as the blood vessels, damage. So, does exercising increase or decrease homocysteine level? According to research, by a presenter named Dr. Lanae Joubert, most increase in homocysteine level occurred when the subjects were exercising strenuously or for a long time. This research seemed to indicate that overexercising can be worse than light activity.
