Main differences in training were that the world class skiers trained ~30%
more volume (hours), and performed more specific speed work.

“When I was young, I was too
slow. I thought I must learn to
run fast by practicing to run fast,
so I ran 100 meters fast 20
times. Then I came back, slow,
slow, slow.” Emil Zatopek
Gerschler’s Sessions: The purpose of each effort
was to get the pulse up to about 180 beats per
minute. After the effort, 90 seconds of recovery was
allowed to get the pulse back down to 120
-
125 beats
per minute. Then the next effort was undertaken. If
the recovery took longer than 90 seconds, the effort
had been too fast.
Rudolph Harbig
1939 Reindell and Waldomer Gershler Emil Zatopek
1948ish
Despite what you read on the internet or in fitness magazines,
interval training has been around a long time!
‘‘It is an important but unsolved question which
type of training is most effective: to maintain a
level representing 90% of the maximal oxygen
uptake for 40 min, or to tax 100% of the
oxygen uptake capacity for 16 min’’
(Åstrand & Rodahl, Textbook of Work
Physiology, 1970). Per Åstrand in 1963

EFFORT MATCHING MODEL
Distribution of individual response to training by group-averaged change in
VO2peak (l/min), power at VO2peak (W), and Power at 4mM blood lactate
concentration (W).
Averaged response for each subject was categorized as negative to trivial:
<4% improvement, moderate: 4–9% improvement, or large:>9%
improvement. The distribution of individual responses was significantly
different among the four groups (P<0.05).

Does this change make a consistent difference

Redrawn after an example provided by J. Stanley

There is some new evidence supporting block training schemes,
and microcycle manipulation may make a difference over
time, but little research has been done on this so far.

Almost all International medal winning endurance athletes have done some training
at altitude (typically 2000-2500m). So, optimization of blood oxygen delivery by stimulating
enhanced red blood cell production may be critical at the world class level. BUT, this is the last
few percent, not the foundation of training, AND there is big individual response variation
and substantial risk of a negative training outcome.
Young athletes and their coaches should do all the other things right, and build a good
endurance training platform before investing lots of time and money on altitude camps.

Heat acclimatization is very important if competitions are held under hot conditions.
Fortunately, a 5-7d acclimatization period is consistently shown to improve
heat removal capacity and heat tolerance. However, effects of «heat adaption» on
performance under normal ambient conditions are probably trivial.

Pacing and racing are sometimes very different. Optimal pace for a given distance
requires both sensitivity to perceptual signals, and practice. Pack racing does not always
involve doing what is «optimal» for the fastest individual time. Therefore specific
«race» training may require a different strategy……
However, both pacing for optimal performance time and race training for optimal race
placement both build on your maximal capacity, which is a function of your committment
To the lower levels of the training hierarchy!

Showing up fit for fight on race day can be worth 0.5-3%, and a lot of research
has been done on the tapering process. Here is a nice article that discusses
that contemporary research, but also some other views (if it ain’t broke don’t fix it).
