Recently I underwent a Bruce Protocol as a part of my exercise physiology lab an obtained a VO2 of 50 but when i received a printout of my ECG it was pointed out to me there was not a Q wave in my QRS complex. I have no signs or symptoms of any cardiovascular problems. Can someone explain why there is an absence of the downward deflection in the QRS.

I would actually have to seen the electrocardiogram to answer your question. However, please be aware that the Q wave may be quite tiny in some of the leads and might be interpreted as not being present. In the left chest leads a small Q wave indicates that the early electrical impulse is moving away from the lead, and that is normal.
I am assuming that your electrocardiographic exercise test using the Bruce Protocol was read as normal by the attending physician, though you don't tell us how long you exercised and what stage you achieved.
Please be aware that I am unable to diagnose medical conditions online.
