I observe my heartbeat throughout every coaching session for atleast a 12 months now. I solely get out of breath, after I method my max heartbeat and my coronary heart is clearly not capable of sustain with the oxygen demand.
An different statement is, that double/single and the tempo of the match have a serious impression on my heartbeat. Doubles is sort of at all times within the vary of 70-90% of my max heartbeat, customary single is sort of at all times above 90%. 90% matches will exhaust me fairly rapidly after 30-40mins, whereas 80-90% matches can go on for hours.
So I assume, that your health just isn’t but capable of sustain with the tempo of those matches/coaching classes.
I’d advocate two issues, first off go to a doc and lets test your well being situation, you simply do not wish to danger any well being points together with your coronary heart contemplating that you’re already not that younger any longer and that badminton is a really demanding sport. And take a look at the Polar OH1, a really exact pusle sensor (nearly as exact as a belt, simply neglect about any pulse sensor clocks) which is very easy to deal with (simply wrap it round arm) and don’t want a connection to your good telephone throughout exercise.
