I have always preferred perceived exertion. Not very scientific, but it's easy to understand and figure out. I generally tell people: "If you can sing a song, you could be working harder, but if you can't get your breath or talk, you need to slow down."

Especially with older people, if we are doing something that is making them hold their breath, I ask them to count down with me. You can't talk and hold your breath!

It is interesting!! But I don't have time to read up on it..and don't want it too technical that I can't understand it. When it can be brought down to simpler terms...I will look into it!! lol :)

emoticon Thank you for that insight in aquatics and heart rate!

Now that the thinking is being updated, I'll bet everyone is going to look back and say, "Well, of COURSE it should have never been calculated based on age!!!"

Not only that, but since I've been researching this, I found that there have been various modifications to the original (220 - age), but those calculations, too, won't stand up under this newer, science-based way of thinking.

Here are the modifications I just referred to:

"In 2001, a University of Colorado team also concluded that the standard heart rate equation was inaccurate for both men and women. They devised a similar formula they said applied to both sexes maximum heart rate equals 208 minus 0.7 times age "

But then it was believed...

"...the right formula for calculating a womans maximum heart rate is a little more complicated:
206 minus 88 percent of a womans age..."

Both quotes from above are from this article:

I sure hope there's more comments on this topic! I'm finding it interesting!

In aquatic exercise, we haven't used target heart rates for a long time because heart rates are lower in the water than for an equivalent intensity on land. Perceived Rate of Exertion is what we use instead. It's subjective and doesn't generate any solid numbers, but it is still useful for the average exerciser.

I have long felt that 220-age numbers were pretty artificial since a friend was driving himself crazy trying to get up to a number calculated that way. He finally saw a cardiologist about it. The doctor told him that because he had been an active athlete for so long, his heart was a little larger than average and its strong muscle pumped out a lot of blood with each beat. So there was no need to beat as fast as the 220-age number!

Someone asked me a heart rate calculation question the other day, and when I went to refresh myself before trying to answer, I was surprised to find there seems to be some UPDATED thinking on this matter.

Before I share the article link that I hope you'll read, here are a few things to glance at that you're going to read in it:

Example:
= Not all 50 year olds wear the same size shoe.
= Not all 50 year olds are in the same fitness shape.
Thus, heart rate would be a huge variable for each 50 year old.

Another illustration (if you WERE using the age-related calculation) would be comparing a 50 year old tiny lady's heart rate calculation versus a 50 year old Amazon-built woman's heart rate calculation. Being the exact same for both just wouldn't make any sense.

Okay, so here's that article to get you started with the science:

/does-your
-heart-rate-really-matter


Just so you know... this is a LOT for me to absorb!

I'm hoping that we can get a discussion going because... well, I need to try to get the NEW information in... so I can discard the outdated information! LOL

P.S. I also had read in a book by Brian Sharkey basically this same information. But I can't find it online (by him) in order to add a link. I feel that he wrote things in a less "scienc-ey" way and it was a bit easier to understand.
