I have further information and it is a faulty valve, and blood pressure is the issue, or a sudden spike in blood pressure. So, it is more of an issue with big loads, she is a fresman and has never lifted and has Hamstring issues. She is not released by the doctor to lift which means anything in the weight room as far as they are concerned. My guess is her quads are to strong for the hamstring, only speculation, but my question is, what to do outside the weight room to improve hamstring strength? And could anyone foresee a problem with med ball or multi-throws with the shot? I'm guessing the load is not high enough to spike blood pressure.
