7. “We did no Olympic lifting (many roads lead to
Rome) but we were explosive as f*** and
won alot of games in the 4th quarter.
Ask anyone we played, you better bring your
hard hat cause its gonna be a war!!! Now
they're just plain soft !!!!!!”
8. “It was enough to get the big guys to reactively
bound over hurdles but when we left they could
all do it with minimal ground contact time
(strive for .15 secs on ground). Now they
do all this Olympic lifting and they are less
explosive!!!!”
9. “Listen you are either a researcher, a data
collector, a phoney, or a coach. I chose to coach.
All my energies went to making my
athletes better! (name) and I only tested
occasionally. We did not want to waste time
losing a training day. You'll see your
athletes getting better.”
10. “Coaches who program speed on day 1 then
agilities on day 2 are just plain stupid!!!!”

“The Colts lead the NFL with 83 games missed due to injury. The Colts
led the NFL in that department last year as well with 89 games missed.
They were second in 2009… the Colts have only had one season when
they had a season where the number of games missed due to injury
was lower than the league average, 2005.”

54. “Squat lifts likely cause of stress fractures in young
athletes, study finds”
“The squat exercise significantly increases the sacral
slope altering the sagittal alignment of the lumbar spine
and pelvis, resulting in horizontalization of the sacrum.
This was most noticeable during the back squat. The
changes would be expected to increase the lumbar
extension forces on the posterior elements of the lumbar
spine and may play a role in adolescent pars fractures.”

64. Vision Training
Contrary to the claims made by proponents of generalized visual training, we found
no evidence that the visual training programmes led to improvements in either
vision or motor performance above and beyond those resulting simply from test
familiarity… (Abernethy et al. 2001.)

strength after 4 weeks of detraining.”

Zaichkowsky, L. D. (1996). The effects of strength training and detraining on children. The Journal of
Strength & Conditioning Research, 10(2), 109-114.
The effects of an 8-week strength training program followed by an 8-week detraining period were
evaluated in 11 boys and 4 girls, ages 7 to 12 years. Three boys and 6 girls matched for age and
level of maturity served as controls. Progressive strength training was performed twice a week on child-
size equipment. Subjects were tested on the following measures: 6 repetition maximum (RIM) leg
extension, 6-RM chest press, vertical jump, and flexibility. Strength training significantly (p < 0.05;
ANOVA) increased 6-RM strength on the leg extension (53.5%) and chest press (41.1%), whereas control
group gains averaged 7.9%. Strength training did not significantly affect other variables. Detraining
resulted in a significant loss of upper (-19.3%) and lower body (-28.1%) strength in the experimental
group. The results suggest that participation in a short-term strength training program will increase the
strength of children; however, strength gains regress toward untrained control values during the
detraining period.

dead tired, like drenched in sweat like I was in a
rainstorm tired…”
“All those guys have improved since last year… I can
definitely see the improvement.”
“Really, I feel like doing that type of training, my
abilities have improved tremendously…”
"I'll get him in crazy shape. You see how he was

81. Coach, I feel faster! I feel more explosive!
How do you know?
83. Scientific Inquiry
What is “explosiveness”?
What is the evidence of “explosiveness”?

Analyzing and Interpret the results
91. Facts or Opinions
Olympic lifting is the best way to develop power. (Stated as a
fact)
I think Olympic lifting is the best way to develop power.
I think Olympic lifting is one of the best ways to develop
power.
Olympic lifting might be one possibility for developing power.
92. Causation or Correlation
We are more powerful because of our use of the Olympic lifts. (Stated as
knowing causation)
We've become more powerful in the lower body from the Olympic lifts.
We've become more powerful in the lower body from the Olympic lifts, as our
measurements by vertical jump indicate.
Olympic lifts are part of our program, which as a whole, has been successful in
enhancing our vertical jump ability, indicating some changes in lower body
power.
95. It’s not the system, method, or
tool… it’s the coach (teacher).
A good coach supersedes all else.
96. Coaching vs. Training vs. Exercising
• Coach (practice logic and reasoning)
• Be present (5 senses, along with COMMON
sense)
• Practicality, because time and energy are finite.
• Observe and reflect (notes)
• Collect data (testing, attendance, self-reporting)
