I played 1 hour and 20 min of tennis today and wore my HR monitor. We played at a fast pace (took little or no breaks between the interchanges). My avg HR was 141, my max was 173. During the last 15 or 20 min my HR was almost always between 160-173, and it would reach the 170s at the greatest of ease (after just a 2 or 3 shots in a rally).
But while it was in the 160s I didn't feel "winded." I was even breathing out of my nose. So how do I interpret this?
Obviously I was more taxed near the end based on the fact that my HR was reaching 170 so much more readily than in the first 15-20 min of the match. Yet at 170 bpm I'm not panting. I'm scared that my HR is that high but I'm really not out of breath.
(1) Is there anything I can take away from this observation?
(2) Should I be careful not to keep my HR above 160 like that for very long?
I see my HR above 160 for 15-20 minutes like that and I get nervous that I am putting my life in danger.
Thanks,
James
