This extract
provides good insight on how our bodies work during running - from
the running on legs to the exchange of potassium and sodium in the
cells - and demonstrates how modern research is changing training.
It is a bit long but it is user-friendly, not burdened with a lot
of technical terms but in language we can understand.
You don't need to be an expert in exercise physiology to run fast,
but you'll surely run faster if your training program is shaped by
the most recent sports science'and if you continually keep up to
date. Elite runners are usually fortunate enough to have coaches
with expertise in exercise physiology who tailor their training
based on the newest thinking in athletic performance. On the other
hand, self-coached runners'like the rest of us'are required to make
our own training decisions. To make good decisions, we need to
understand the basic physiological objectives of training and the
cause-effect relationships between the various types of training and
these objectives.
How do you train to lose weight? You don't. If your primary goal is
to lose weight, see a weight loss counselor. If your primary goal is
to become a better runner, and you happen to be carrying a few extra
pounds, you're best off training and eating for maximum performance.
That is, training and eating the same way you would if you were
already at an ideal weight. Your weight will take care of itself.
Ultimately, quality training is more beneficial than caloric
restriction for body composition (i.e., body fat percentage, a truer
measure of health and fitness than weight, which is linked to height
and body type). In fact, numerous studies have shown that caloric
restriction negatively affects training.
This one is technical but has good speed training regimens.
