2. What is Periodization?
• Subdivision of the ATP into shorter periods/cycles
(issurin, 2010)
• Goal: Achieve peak performance while remaining
injury free (or as close to as possible)
www.mensjournal.com
3. What is Periodization?
“A training plan whereby peak performance is
brought about through the potentiation of
biomotors and the management of fatigue and
accommodation” (Turner, 2011)
4. What is Periodization?
• Inverse relationship
between Vol. and Int.
• Applied in cyclic basis:
Macro-, meso-, and
microcycles from high
volume to high intensity
• General to special tasks
• Cumulative Training Effect
Turner, 2011; Issurin, 2010
6. Recovery and Adaptation
• Overload and Recovery = Adaptation +
Peaking
Turner, 2011
Basic model of periodization entailing little
variation and relatively flat workloads within each
mesocycle.
8. General Adaptation Syndrome
• Overload principle
• Stress response is
the same regardless
of the stressor
Turner, 2011
The GAS paradigm that suggests that the body’s response to
stress is always the same despite the stressor. Here, the
body undergoes an alarm phase and a resistance phase
before supercompensation is experienced.
P = performance; T = time.
9. Stimulus-Fatigue-Recovery-Adaptation
Theory (SFRA)
• Fatigue accumulates in
proportion to the strength
and duration of the
stimulus (stress)
• The body then rests,
fatigue dissipates, then
adaptation occurs
(supercompensation)
The stimulus-fatigue-recovery-adaptation theory
concept suggests that fatigue accumulates in proportion
to the strength and duration of a stimulus, and then
after rest, fatigue is dissipated and supercompensation
occurs. P = performance; T = time.
Turner, 2011
10. Fitness-Fatigue Paradigm
• Most prevailing theory
of training and
adaptation
The fitness-fatigue paradigm suggests that fitness (top curve) and
fatigue (bottom curve) occur concurrently, and only when fatigue has
dissipated, does fitness gains become apparent and athlete
preparedness (blue line) becomes apparent and optimized (x-axis,
time).
Turner, 2011
11. Fitness-Fatigue Paradigm
The traditional approach to the design of periodized training, which is attributed to
the work of Matveyev, (y axis, volume load; x axis, week).
Turner, 2011
12. Why The Need to Change Focus?
• ‘The principle of diminishing returns”
(Zatsiorsky and Kraemer, 2006)
• Nervous system no longer challenged to
adapt.
• Exercise deletion and re-presentation.
• Change volume, frequency, or intensity.
• Too much variability = reduce opportunity to
adapt.
13. Advanced Models of Periodization
The conjugate sequence system pioneered by Verkhoshansky. This system involves periods of
planned overreaching followed by periods of restitution.
Turner, 2011
14. The Taper
• Progressive increase in volume and load =
cumulative fatigue and overstress of the
neuroendocrine system
• Reduce volume load in the final days before
competition.
• Aim: Optimize performance
• Goal: Dissipate accumulated fatigue
• Leads to significant increase in performance
(Houmard, 1994)
15. The Taper
• 3 Types:
– Step
– Linear
– Exponential
• Optimal:
– 2-weeks (Bosquet,
2007)
– 1-4 weeks (Mujika
and Padilla, 2003)

17. Take-Home Message
• Structure your season into specific training blocks
• Within each block, 60-70% of all sessions are devoted to 2-3
targets.
• Focus on developing your aerobic base before shifting into a
specific phase
• Ensure sufficient recovery after high volume weeks/sessions
• Factor in detraining or lower load weeks strategically within each
mesocycle
• Take longer recovery after high to maximum effort sessions.
• Don’t schedule two consecutive high or maximum volume sessions
with high cognitive or tactical involvement
• Taper
• Figure out what works for you – we are all different!

Editor's Notes
ATP: Annual Training Cycle
endurance coaches and athletes manipulate training intensity and volume during their annual training plan in order to avoid stagnation in adaptation (caused mainly by training monotony) and to potentially augment training adaptations
Cumulative training effect: Changes in physiological capabilities and level of physical/technical abilities resulting from a long-lasting athletic performance.
Most pronounced change is in aerobic abilities (aerobic enzyme increase)
The greater the number of loading steps, the greater the number of unloading steps required.
Training adaptations take place during the recovery periods – goal is to reduce accumulated fatigue.
Professional athletes can go home and rest, while the semi-pro or amateur has to go work – implications for recovery.
Three principles of recovery: The general adaptation syndrome (GAS), the stimulus-fatigue-recovery-adaptation theory, and the ditness-fatigue theory
1:1, 2:1. 3:1 4:1 loading patterns
The alarm phase (phase 1) = recognition and initial response to the session (fatigue, stiffness, or DOMS).
The resistance phase (phase 2) is initiated in which the body is returned to either its pre-exercise session homeostasis or its new adapted higher state (i.e., supercompensation occurs).
Finally, and assuming that the accumulation of stress is too great (e.g., the absence of an unloading week), the exhaustion phase (phase 3) occurs
Concept also suggests that is the stress is not applied with suffecient frequency (density), detraining occurs.
Basically, involution time is influenced by the length of the preperation period (the greater the prep period the greater the residual effects) – therefore the subsequent prep periods in one macrocycle can actually decrease.
The fitness-fatigue paradigm suggests that fitness (top curve) and fatigue (bottom curve) occur concurrently, and only when fatigue has dissipated, does fitness gains become apparent and athlete
Unlike the GAS and SFRA concepts, which assume that fitness and fatigue share a cause and effect relationship, the Fit-Fat model suggests that they demonstrate an inverse relationship.
Implies that strategies that maximize fitness and minimize fatigue will have the greatest potential to optimize athlete preparedness
if the athlete is too tired to repeat the same exercise with an acceptable quality they may still be able to perform another
Conjugated Sequence – periods of planned overreaching followed by periods of restitution
A step
taper involves an immediate and abrupt
decrease in training volume for example,
decreasing the volume load by 50%
on the first day of the taper and
maintaining this throughout. A linear
taper involves gradually decreasing
the volume load in a linear fashion
for example, by 5% of initial values
every workout. The exponential taper
decreases volume at a rate proportional
to its current value (half-life), for
example, by 5% of the previous session
values every workout. In addition,
exponential tapers can have fast or
slow decay rates.
