1/21

General Theories of Training

One Factor Theory (Supercompensation)

Two Factor Theory (Fitness-Fatigue)


2/21

One Factor Theory

(Supercompensation)

One exercise bout depletes biochemical substances

During the restoration, these substances achieve levels

above initial levels (e.g. glycogen)

Zatsiorsky, 2006 Science and Practice of Strength Training

Implications

Must optimize interval between workouts

Time workout for supercompensation

phase (How do you know?)

Training load optimal to induce

supercompensation

What substance(s) should be used as themarker (s)? Could these be used as

overtraining markers?


5/21

Periodization

wChanges in exercise stimulus over a specific period tokeep an individual from overtraining

wCycle of five phases: four active phases followed by oneactive recovery phase

wEach phase gradually decreases volume and graduallyincreases intensity


6/21

Periodization

McArdle, Katch, and Katch, 2001.


7/21

Overloading microcycle

AKA Impact microcycle



8/21

Two Factor Theory

(Fitness-Fatigue) Includes fast and slow changing elements of

preparedness

Physical fitness is slow changing

The fast changing is similar to the one factortheory

Immediate training effect combine fitness gainand fatigue

Fitness long lasting (72 hours), moderate

magnitude Fatigue is large in magnitude, short duration (24

hours?)

Terminology/Considerations

Acute effects: Effects during exercise

Immediate effects: Effects observedfollowing an exercise bout.

Cumulative effects: Additive effects ofseveral bouts of exercise

Delayed effects: not apparent until a

period of training is complete Residuals effects: remain after training

ends


11/21

Other major challenges

Providing overload without

Inducing overtraining syndrome

Causing injury


12/21

Review

What physiological elements contribute to

maximal velocity in a sprinter?

How would you train these elements?

acceleration


16/21

Measuring Explosive strength

Index of Explosive strength

IES=Fm/Tm Reactivity coefficient

RC=Fm/(TmW) w=athletes weight

Force gradient

S-gradient=F0.5/T0.5 A-gradient

F0.5/(Tmax-T0.5)


17/21

Strength vs. acceleration


18/21

Explosive strength

Results of Resistance Training on Muscle Strength

in Males

w Increased muscle size (hypertrophy).

w Alterations of neural control of trained muscle.
