More than likely a silly question but...

Is 45 minutes of a heart rate cycling between 140 to 165 as a result of doing seven sets of deads physiologicially the same as 45 minutes of the same heart rates on the eliptical trainer as regards heart health?

I realize that there is a profound difference as to the impact on the rest of the body, but is there any difference between the two specifically regarding cardiac function?

thanks,

preacher

Preacher - in short, no. Your heart is not particularly concerned about which exercise method is elevating your heart rate...just that it is elevated. If it is at 140 to 165 for DL's, Tabata squats or running intervals the benefit to the heart is the same. The difference comes as a result of varying levels of initensity, duration and frequency.

Though maligned with no lack of frequency here in the message boards low intensity, aerobic exercise done for extended periods builds a certain kind of fitness short duration intensity cannot. The argument is made for the advantages of shorter duration training, but if you are going to go long, some of your training has to be of long duration.

Your DL's are going to have a profoundly more significant and developmental effect on you than running for the same period of time at the same intensity, but your heart won't appreciate that difference.

Take a look at books by Jeff Galloway, Jack Daniels and Phil Maffetone and for a really scientific teatment of the subject take a look at "Training Lactate Pulserate".

Thanks Eugene,

That is what I expected, but this will help settle an argument that came up at the gym today.

Randy - My pleasure. What changes things is the level of intensity that you use. If you run, lift, row or bike at the same level of intensity (ie heart rate) the CV development will be the same. But don't compare mall walking for 20 minutes with a 20 minute CF workout. Completely different animal there.

Scott Brown in the foreground the best all around athlete on our team, Micha Lundborg in the middle who just recently got his muscle up and can now do 42 pullups and Brian "Rhabdo" Anderson furthest away who can do 37 pullups is just a few pounds away from a below parallel squat with 300 pounds. Tough crew. They are clearly UICF.
