Introduction
“The human body is an adaptable living organism. It is
nothing more than an interdependent matrix system that
communicates with and amongst itself all day long
through electronically charged molecules-you are an
ever evolving and fluctuating organism that is selfregulating and supercompensating-you are nothing
more than a bio-electrical field that is hell bent on one
function--SURVIVAL!”

Physical Conditioning
Strength Characteristics
Isometric force: time curve indicating maximal strength, maximal rate of force development, and force at
200 ms for untrained, heavy-resistance strength-trained, and explosive-strength-trained subjects
(adapted from Häkkinen et al., 1985 a, b).
What is Strength?

The ability to exert a force against a resistance.
F=ma (Newton’s 2nd Law of Motion)

Dynamic strength is defined as the maximal ability
(capacity) of a muscle to exert force or torque at a
specified velocity (Knuttgen & Kraemer, 1987)
What is Strength?
Force-velocity curve showing how power can be related to these qualities
What is Conditioning?







Capacity for training
Building blocks for future work
‘Prevention’ of injury
Physical preparation
3-D Training
Lower level training – pre-strength
Auxiliary training – parallel to strength
Planning & Organising
“If you fail to plan, you plan to fail”

Priorities
Priorities
“Be careful over emphasising qualities that are not
specific to the primary components or objectives of
the training cycle, because you will have too many
qualities competing for the draw on the nervous
system.”
Charlie Francis

Warm-ups
‘Core’ conditioning
Drills
Plyometrics
Hurdle work
Lifting technique
Injury prevention / muscle balance
Assisted running / jumping (Ritzdorf, 1998)

Decreasing the external loads when performing jumps is a
good stimulus to develop the velocity component of
explosive strength.

Good Coaching/Good Training
“Repetition is the mother of learning”
Latin Proverb
“Precise repetition is the mother of excellence”

Quality is better than quantity, but a larger
quantity of quality work is best

“Intension to move the bar quickly rather than the
actual speed of the bar is the goal” (Young & Bilby,
1993)
Better recruitment of motor units
Synchronisation
Muscles activated at higher frequency

Monitoring Directs Training

Monitoring on a regular basis could be important in
helping the coach to determine which component is
deficient so that training can be implemented to
address the deficiency and to provide motivation to
the athlete.
