Warm ups

I tried out a few routines to warm up for practice and competition. I first went with a rigorous bike warm up for 5 minutes.  Then I tried drills.  I've settled on a simple routine involving 2 minutes on a stationary bike and stretching.  Followed by sprints on a court.  Ideally at the end of my warmup, my heart rate has peaked around 150 and settled down to 125.  I begin to fatigue and lose focus when my HR exceeds 180. During my warmup I want to avoid extending my heart rate beyond 150.  Doing drills is not a good thing for me at this stage of my fitness development because it raises my heart rate beyond 170.  A precipitous drop from 180 can also affect my concentration.  So I shouldn't start peak my HR early.

I've heard from a doctor and other athletes that my heart rate is high for someone who plays sports.  I don't know what my HR was when I competed in my twenties and thirties, but I'm relatively certain that I don't work up my aerobic condition enough to have a steady low HR.  Still I don't want my HR to hit 190 which it did this week when I practiced after a full dinner.  I must remember to hold my food intake on active days or nights.
