Supertraining

Hello C. Chaney,

I'm not completely sure on this one, but think that it is just as subjective
as a finger print and can be found out or better estimated via a VO2M test
as I seem to recall reading one of Swains books [I think the simplified
metabolic equations] where there was a comparison or equation relating VO2M
to HRM.

The 220 was based off of an estimation of an infants hear rate at birth, so
the HRM of 220-Age is a good generalized estimation; however, there have
been some who identified the 220 for males and 226 for females. 

Both the ACSM and NSCA have accepted and published the HRR or Karvonen
[(220-age-RHR)*(55-90%) + RHR] method for CV prescription and have grown
away from the HMR [(220-Age)*(55-90%)].  NASM has flipped from the HRR
[1998] back to that of the HRM [more recent times] for cardiovascular
training as well, so this is one of the items that can also create some
additional confusion as well. I could not get a straight answer from NASM
for the reasoning other than "It's just better." I know that it is a small
number variation, but what is your opinion of the methods of HRM vs. HRR? 

Thank you,

Subject: [Supertraining] Max heart rate

 

I had a client ask a strange question the other day. His question 
was "what is the max heart rate that a person can maintain and sustain 
will working cardio conditioning until the body will shut down." My 
educated guess was 220. But know that the body will voluntarily slow 
down with the fatigue and lactic acid overcoming the person. Has there 
been any studies or a definite answers for this type of performance.

Thank you for you time on reading my question.
