Health And General Life Care: [Supertraining] Re: Strength Training for a 800m runner(In Season)

Ralph

I'm not sure that I made myself clear in the posts, no-one is asking Brian
not to do time on the track and I'm certain that his coach would be doing
intervals, however I'm fairly certain that since Brian has worked hard
developing strength in the off season that has contributed well to improved
running, and that he should maintain that strength in manner that best
relates to the use of type II muscle fibre.

My in season programme last somewhere between 20 and 45 minutes. Twice or
three times per week depending on how close to the race day.

With regards to anaerobic vrs aerobic usage, these are interesting, however
I often wonder how many of the aerobic markers relate to the body trying to
catch up the anaerobic expenditure of energy. In the 100m sprint for
instance in a 10 second burst, who would imagine that aerobic systems are
challenged at all, but 20 odd percent of bio markers indicate aerobic work -
perhaps due to the body catching up with the anaerobic muscle performance, I
would have thought the same for the 400, except that because the race goes
on longer there is longer for the aerobic systems to get involved in
processing the anaerobic work of the muscles. The reason I believe this is
that in order to move the body body powerfully and fast the work must
involve significant contributions from type II a & b muscles. Type IIb have
very little aerobic contribution, but would load the systems with products
from anaerobic energy systems. Type IIa muscle are much more capable of
converting anaerobic products and using glycogen for restoring the ATP
resulting in markers of apparent aerobic respiration. Any comments?

I agree that intervals are good, some good studies on that
topic were just recently posted. I'm still convinced that appropriate time in the gym is
important. If Brian is going to run the 400m hurdle later this year, I'm
not sure that he should drop to much explosion from his work out and
continue with speed work. If the 800m indoor season is part of development
for that race, then the whole season needs to be kept in balance.
