3. This presentation will be different.
◦ The first part will be philosophical
◦ The 2nd part will be fun stuff- real world
examples and application
◦ The last part will be controversial
4. Evidence based?
only 13% of all treatments used by doctors have good
evidence
an additional 21% of treatments that are “likely”
beneficial.
What about the other 66%?
Is Science Bad? No, but…
You have to understand it‟s limitations in
order to know how to use it.
5. Science conforms to the individual:
Average vs. Individual
Research focuses on the average.
Responder vs. non responder in coach speak is actually an
issue of applying the correct stimulus
Do we really expect 4mi tempo at X pace to work for
everyone?
Timmons et al.(2011) put it best when talking about the
non-responder phenomenon:
“It is also an observation that is largely ignored by the
majority of researchers interested in the health benefits
of exercise training, presumably because the focus has
been on the “average” health benefits within a population
and the desire to have a simple health promotion
message.”
6. ◦ Measurement
We overemphasize the importance of what we can
measure.
Science evolves based on what we can measure at the
time.
VO2max
Vollaard et al. (2009) “Moreover, we demonstrate that
VO2max and aerobic performance associate with distinct and
separate physiological and biochemical endpoints,
suggesting that proposed models for the determinants of
endurance performance may need to be revisited (pg. 1483)”.
7. Researchers=
No change
Coaches=WHY
the individual
differences?

increase I sure think it
works!)

"Live high - train low" using normobaric hypoxia: A double-blinded, placebo-
controlled study.
8. The isolation approach:
Scientist- break It down to isolate a variable
X effects Y and Y is RELATED to performance so it
should work…
Coach- Global approach
X effects A,B,C,D, etc. How everything interacts is
more important
All sorts of other crap
(population, equipment, study
length, long term vs. short term, etc.)
9. 1. Deciding whether something is
useful:
Stool test
1.Practical- Does it work in the
“real world.”
2. Research- Is there scientific
research on it and does it confirm
that it works?
3. Theory- Is there a legitimate,
non-pseudoscientific, theory for
why it might work?
10. 2. Using scientific Knowledge to formulate Real
world ideas
Use knowledge of HOW body works and learn
how to apply that knowledge.

18. Using Smart Phones
◦ Data base
◦ Rate:

Workout rating
“Pop” in legs
Injuries/Soreness
◦ Simple Reaction Test

Looks at neural fatigue somewhat
◦ Look for trends and correlate to training logs

20. Fasted Runs
◦ Theory-low glycogen is signal for adaptation. Shifts fuel
usage towards more fat
◦ Research- Drust et al.(2009), Yeo et al. (2008)
◦ Practical-Lydiard, Cerutty, Van Aaken,Kenyans,
Canadians (!?)
Practical- start with running before breakfast for 30min,
slowly increase up to close to 2hrs for marathoners. 1-2x a
week depending on goal/time. EASY training after
(RECOVER)
Adapting the gut
◦ Can increase the amount of Carbohydrate our gut can
process=enhanced marathon performance with lower GI
stress
◦ Practical experience- eat dinner, go run- after a week
you‟ll be fine with no GI problems.

Interventions: The Potential Benefits of “Low Carbohydrate” Training. Kinesiology

21. Knowledge:
◦ Research shows knowledge of external feedback affects
performance
◦ Real world experience shows people occasionally
“rebound” after looking like death in a race because they
realize they are close to finish…
Real World Solution
◦ Take it all away.
◦ Blind Feedback workouts- do workouts without
knowledge of how long the rep is, what exact pace
is, when surges will come,etc.
◦ Switches focus to training on dealing with internal
cues/feedback and improves psychological drive during
uncertainty.
22. Knowledge:
◦ “The greater the ability of the athlete to oppose fatigue (by maintaining
strength levels), the smaller the drop in speed and consequently the better the
performance.” Miguel et al. 2004
◦ 400m race- (Numella et al. 1992,1994)
Force production drops 16% after 300m and 25% after 400m.
Increase in muscle activity (measured by EMG) to compensate for
failure of muscle fibers that were doing the work.
Kick development:
◦ 1.Increase maximum fibers recruited
Flat Sprints, Hill Sprints, Power work
◦ 2. Improve ability to use for prolonged time
Circuits, alternations, hills+flats
◦ 3. Learn to recruit them under high acidity
fast workouts with bounding/hills
2x500(200 at faster than 800 pace, 100m bound at near mile pace, 200m kick in)
full rest between
Works by 1st part Increase lactate/fatigue, 2nd part increases fibers recruited, last part
teaches you to use those fibers while fatigued
Circuits with fast speed running, max intensity bounding and exercises

Why care?
•Interactions matter:
•AMPK inhibits mTOR
•Do endurance work AFTER strength and you inhibit hypertrophy
•Knowledge of stimulus
•Explains why training does what:
•AMPK and CaMK can both Increase mitochondria.
•AMPK= activated through endurance.
•CaMK= activated through intense intervals.

27. 1. Remember the Brain?
◦ Most new research/ideas revolve on the change in
mindset.
◦ The brain is a smart controller, synthesizing
information, making calculations based on complex
algorithm, and dictating what happens.
◦ Input/Feedback is key.
2. Body is well designed.
◦ Timing matters, and knowing when to manipulate
matters.
28. Baron et al.(2012). The role of emotions on pacing
strategies and
performance in middle and long duration sport
events
29. •Feedback
•Block with drugs and pacing is erratic (out hard and die)
•Deception
•Castle et al.- exercise in heat is effected by what
thermometer reads
•Ness and Patton- changed labels of weights after 5 weeks,
athletes lifted 20lb more for their max
•Knowing vs. not knowing (distance, reps, pace, etc.)
•Manipulating psychological drive
•dissociative cognitive strategy
•TRAINING- Training improves our ability to assimilate feedback and
use it better in regards to riding that edge/pacing.
•Become an Expert!

exercise may be the „competition‟
between psychological drives and
physiological homeostatic control
mechanisms” St. Clair Gibson,2013

32. Anti-inflammatory
◦ At what point during the inflammatory cycle do you
impede?
Refueling
◦ Low Glycogen needed for certain types of adaptations
Hydration
◦ In adapting to high heat/humidity, research shows need
some dehydration to get beneficial effects
Supplement intake
◦ Hepcidin rises post workout for ~3-4hrs…limits Iron
absorption
Taking iron pill in that window…decreases absorption…
33. Don‟t over recover.
Periodize recovery so you use it when you
need it
◦ Base and Pre competition phase
Damage is good
Selectively use recovery modalities when athlete is on
“edge”
◦ Peaking
Slight increase in recovery modalities because
emphasis shifts from training to racing
34. Testosterone and muscle growth
◦ Elevated systemic hormones does not effect muscle
hypertrophy
Chronically supraphysiological levels (i.e. drugs) aids
muscle growth, not what we get in regular acute
exercise.
Compression Socks
◦ Blood Flow not the issue
◦ Modulates muscle “tuning” (think vibrations)
Stretching
Hands over head
◦ Let your kids fall over
Elevations in ostensibly anabolic hormones with resistance exercise enhance neither
training2 induced muscle hypertrophy nor strength of the elbow flexors. J Appl Physiol (
35. Cushioning and

Running surface-
◦ “hard” surfaces not evil

to it.

37. Use Science, don‟t be married to it.
Stimulus-> Adaptation
◦ What adaptation are you looking for?
Lab vs. Real World
Average vs. Individuals
Know what you‟re testing for and what the
measurement means.
