Q+A: I'm 40. Is a maximum heart rate of 202 safe?

Q I’m in my mid-40s, push myself quite hard in training, and feel great and in good shape. However, after buying a heart rate monitor, I was shocked to find that my resting heart rate was 46, and that I could reach a maximum of 202bpm during hard efforts. Is this safe, or am I pushing myself too hard and likely to go out with a bang?

A Far from being a cause for distress, your impressive heart rate range is something to boast about! A resting rate of 46 indicates that your heart is well conditioned and efficient, with an excellent stroke volume (volume of blood pumped per beat). A useful analogy to help you understand what this means for your body is to imagine using a bucket to bail out a leaky boat. The bigger the bucket, the fewer times you must fill and tip out the bucket in order to keep the leak from sinking the boat. Your low resting heart rate indicates that you have a big bucket. The fact that your stroke volume is relatively high, and your maximum heart rate is over 200bpm is a good thing, because it means that you have a large cardiac output (flow of blood in litres per minute = heart rate x stroke volume). Cardiac output is argued to be the main limiting factor to your maximal oxygen uptake, and the more oxygen you can process, the more efficiently you use energy – an obvious benefit for endurance performance.

To put your mind at ease, some elite cyclists have resting heart rates as low as 36bpm, and it is not unusual to see heart rates of over 200bpm. However, your 202bpm is impressive for someone in their 40s, because maximum heart rate declines as we get older. The rough rule of thumb for estimating your ‘age-predicted’ maximum heart rate is to subtract 0.8 times your age from 214 for men, or subtract 0.9 times your age from 209 for women. The fact that your maximum is higher than the number that this equation predicts is not a cause for concern. Maximum heart rates are not as fixed as is sometimes believed, and it is also thought that the decline in maximum heart rate is less marked in those who are physically active. So far from ‘going out with a bang’, it looks as if you’ll be able to enjoy a high level of performance for many years to come.

When I have been running for about 15mins half of my face goes red and hot and the other side stays white and cold. I do various other sports and this does not happen. It is so obvious sometimes that it looks like someone has painted a line down the middle of my face. Is there anyone else that seems to have this condition as even the doctor has no idea.

Hi Nikki, I have had the same conundrum for some years now. I started with my right arm not sweating and feeling cooler than my left, which seemed to sweat normally or maybe a bit more than usual. I also discovered that the right side of my face stayed pale and the left hand side was red and perspiring. I was referred to a neurologist, in Oxford, and his answer was that it was a "conundrum." It hasn't affected me adversely in any way. I'm not sure if I should be glad that I'm not the only one with a similar condition, and neither are you.

it's called harlequin syndrome!


usually confined to the face, occasionally involves the arm also.

usually just an innocent phenomenon due to an asymmetry in the nerve supply to the face

You learn something every day. Though you'd think the condition could have been given a better name - it implies you're wearing a hat with bells on !

I was going to scream after reading this "advice", but then I realized it´s from 2000. If the guy asking took her advice, there´s no doubt in my mind the guy´s been dead for many years...

Too bad you trust your health to very first person that identifies himself as a "Dr.". I´m sure she slept perfectly well that night...

 Please guys, do your own research!!

Do you think it might be referring to the original Q&A article, rather than the topic it's spawned?

Otherwise, yeah, baffled too.
