Yes: If you are very physically fit, a 44-50 resting pr is great. Your pr should increase with exercise unless you have a heart rhythm disorder which will require a thorough investigation.

Yes: Even if your resting heart rate is low, it is likely that your sinus node rate (pacemaker in the normal heart) will respond with an increase in heart rate during exercise.
