9. Principles of Strength Training
Overload . . .
Overload might be achieved by increasing the
Resistance
Repetitions or sets

11.Principles of Strength Training
Specificity . . .
Effects of the conditioning program are ________to the
type of stress applied and to the particular ________of
the body that is exercised.
“If the body is placed under stress of varying intensities

adapting specifically to the imposed demands” (Allman
1974).
12.Principles of Strength Training

varying exercise selection, intensity, volume, and
load.
15. Periodization
