Concerned about my daught, who is, until the last couple weeks, the one of the top cross country skiers in the nation. She cannot train nor race what so ever. Her resting hr is high, ANA positive. Back in the Fall she experienced drastic weight loss due to braces, but recovered it back within a month. Eventhough she had consistently completed in the top 3's in provincial and national races, her energy was never there until a race 2 weeks ago. She was complaining of sore knees, deep sore muscles and slightly tired. Can a ANA (+) test suggest overtraining, or can there be an autoimmunity problem, such as Hashimato's, or even Lymes disease?
