Default Training polarization (Stephen Seiler)

Surprisingly, the MSU library doesn't have access to it, so I put in an
interlibrary loan request with the town library. It should come soon, as
I think they receive articles by email. I'll let you know.

No reason recreational runners should be higher in Norway that I know
of. It depends a lot on age. Mine was last tested (5200' altitude) at
59 when I was 52 yrs old (max HRM = 184), which is considered high -
they called it "Olympic level" - and it looks now like I may have even
developed exercise-induced asthma by then. That test wasn't in ski
season and I wasn't really a runner, tho I often jogged the downhills on
hikes.

I'm looking at the video and the polarized training group VO2 max was
61 +/- 8.4 and the other group was 64.1 +/- 7.3. Mean difference in 10k
times for those who actually trained as instructed was 7.0 +/- 3.6% vs.
1.6 +/- 4% (n for polarized training group not given, tho Seiler seems
to imply everyone). Both those group VO2 max's suggest recreational
runners who train and maybe race a lot and who do so in part because
they were born with healthy oxygen handling capacities that bring
results which reinforce their interest.

Thanks for the offer. The first slide on this section is at 27:!6 of
the video. Title of study is "Does Polarized Training Improve
Performance in Recreational Runners" Journal of Sport Physiology and
Performance, 2013 (Iker Munoz,Seiler, ....) (ePublished ahead of
print) VO2 Max was around 62--I have no idea if that's typical or
high (I assume "recreational athlete" in Norway may be at a bit of a
higher level than here in the States.)
