Strength & Endurance, Pt 3 - Systemic and Cardiovascular Responses to Training

Nice summary of a lot of challenging to summarize research.

A question about the arterial stiffness issue: shouldn't there be a way of measuring the end point of interest -- namely, the probability of a cardiac event -- in relation to resistance training -- as opposed to the less obvious end point of increased stiffness? Is there any evidence as to whether those who practice resistance training are more or less likely to have a heart attack or stroke than those who train in the endurance end of the spectrum or maybe even those who don't train?

Hi Tallison,

In looking through the current research in preparation for our presentation, I did not come across any such data. A few things we do know from the literature:

1) Both strength training and endurance training measurably improve several markers of cardiovascular disease
2) Physical strength and aerobic fitness have both been shown to positively affect all cause mortality (which would indicate that both would make you less likely to suffer from a MI or CVA, but the data does not expressly say that)
3) Being sedentary is not good for your long term cardiovascular health when compared to doing any sort of exercise or physical activity.

For now, all we can do is base our conclusions off of the data that we currently have available.
