Hi,

Im 21 and 155lbs, im not too fat, infact most people say i need to gain weight (i have a little bit of a tummy, but nothing too bad, the rest of my body is pretty much under-developed).

Anyway, ive done no excercise at all for about 5/6 years, and lived off junk food. About 3 weeks ago i joined a gym and have been doing quite a bit of CV, my heart rate is normally about 165-170 while on the bike and stepper thing. Anyway, today i thought i would try to jog to see how ive come along (i tried jogging before joining the gym and could only do about 3/4 mins jogging before having to stop). When i got on i found that jogging was no problem and i done a good 30 minute jog without getting tired or needing to stop at all, but one thing that did scare me was that my heart rate went as high as 183, althought i was still comfortable at this 183 beats per minute it seemed a little high to me, what do you guys think?

Cheers

Allan

According to Sam Fox’s maximum heart rate formula, 220 minus your age, you should be able get your heart rate to 199 beats per minute without any difficulty. However, there are some caveats.

In 1970, heart specialist Sam Fox and researcher William Haskell were on a plane to a meeting. Looking over the data on some research papers, Sam Fox observed that the maximum heart rate appeared to be 220 minus one’s age without putting his theory through the rigours of scientific testing.

The formula is wrong in that the maximum heart rate is related to your fitness level. A fit 60 year old can get his heart rate to 210 without any difficulty while an unfit 20 year old will struggle at 120. Your legs act like a second heart to pump the blood back toward the heart. The stronger your legs are, the greater the quantity of blood that is driven to the heart. This is known as the Bainbridge reflex. How quickly you can contract and relax your leg muscles determine how fast the heart beats. Stronger legs will produce a faster heart rate while weaker legs results in a lower rate.

If you can get your heart rate to 183 and not feel light-headed or dizzy, you have proper conditioning. You can measure your fitness level by taking your heart rate as soon as you stop a vigorous exercise, and take it again one minute later. If the rate drop is greater than 30 beats per minute, consider yourself as better than average, but if the rate falls less than 20, you have room for improvement. The faster your heart rate returns to its resting rate, the fitter you are.
