Training
- Strength Training
Better performances can be the product of a
number of factors. This product is primarily the outcome of efficient technique,
the progression of speed and the maturing competitive attitude on a sound
basis of general endurance, all round strength and general mobility. The
development of all round strength is best achieved via circuit training
and then progressing this through strength training. Weight training is
the most widely used and popular method of increasing strength.
A
muscle will only strengthen when forced to operate beyond its customary
intensity (overload). Overload can be progressed by increasing the :
-
resistance e.g. adding 10kg to the barbell .
-
number of repetitions with a particular weight.
-
number of sets of the exercise
-
intensity, i.e. reducing the recovery periods.
The
exercise must be specific to the type of strength required, and is therefore
related to the particular demands of the event (specificity). The coach
should have knowledge of the predominant types of muscular activity associated
with the particular event, the movement pattern involved and the type of
strength required. Exercises should be identified that will produce the
desired development. Although specificity is important, it is necessary
in every schedule to include exercises of a general nature - e.g.
-
Power Clean
-
Bench Press
-
Back Squats
-
Sit Ups
-
Shoulder Press
-
Chest Press
-
Lat Pull downs
-
Lower Back Extensions
-
Tricep Press
-
Calf Raise
-
Bicep Curls
-
Leg Curls
-
Leg Extension
These
general exercises give a balanced development, and provide a strong base
upon which highly specific exercise can be built.
The
amount of weight to be used should be based on a percentage of the maximum
amount of weight that can be lifted one time, generally referred to as one
repetition maximum (1RM). The maximum number of repetitions performed before
fatigue prohibits the completion of an additional repetition is a function
of the weight used, referred to as repetition maximum (RM), and reflects
the intensity of the exercise. A weight load that produces fatigue on the
third repetition is termed a three repetition maximum (3RM) and corresponds
to approximately 85% of the weight that could be lifted for 1RM.
The
number of repetitions performed to fatigue is an important consideration
in designing a strength training programme. The greatest strength gains
appear to result from working with 4-6RM. Increasing this to 12-20RM favours
the increase in muscle endurance and mass.
Three
sets of 8-12RM performed 3 days a week is a typical strength training programme.
The optimal number of sets of an exercise to develop muscle strength remains
controversial. In a number of studies comparing multiple set programmes
to produce greater strength gains than a single set, the majority of studies
indicate that there is not a significant difference.
Handling
heavy weights in the pursuit of strength will require a recovery of 3-5
minutes between sets, but only minimum recovery should be taken if strength
endurance is the aim. The majority of athletic events are fast and dynamic,
and therefore this quality must be reflected in the athlete's strength work.
This
is really linked with recovery since the body must be allowed to recover
from the strenuous demands of strength training. As a 'rule of thumb' 48
hours should elapse between sessions. If training strenuously, any athlete
will find it extremely difficult to maintain the same level of lifting at
each session, and the total poundage lifted in each session would be better
to be varied (e.g. a high, low and medium volume session) each week.
There
are variable resistance machines and free weights. Variable resistance machines
are effective tools for building strength and muscle tone and are designed
to work the target muscle in isolation, without the assistance of the surrounding
muscles. Free weights (barbells, dumbbells and machines that provide the
same equal resistance to a muscle) allow you not only to target a particular
muscle group but to engage other muscles that assist in the work. Once they
are conditioned, these assisting muscles help you to increase the weight
you use in training the target muscles in order to stimulate the most growth
in muscle fibers. The assisting muscles help stabilize the body, support
limbs and maintain posture during a lift. Lifting free weights improves
your co-ordination by improving the neuromuscular pathways that connect
your muscles to the central nervous system.
Simple
Sets e.g. 3 x 8 with 70% - meaning
three sets of eight repetitions with a weight of 70% of maximum for one
repetition. This is the system that all novice lifters should work on, because
the high number of repetitions enables the lifter to learn correct technique,
and thereby reduce the risk of injury.
Pyramid
System Here the load is increased and the repetitions are reduced (e.g.
100kg x10, 120kg x 5, 130kg x 4, 140kg x 3, 150kg x 2, 160kg x 1). Pyramid
lifting is only for experienced lifters who have an established good technique.
Super
Setting This consists of performing two or three exercises continuously,
without rest in between sets, until all exercises have been performed. The
normal 'between sets' rest is taken before the next circuit of exercises
is commenced.
Training
Programmes
Use
the above notes to assist you in the preparation of a general weight training
programme, to develop your general strength, and a specific weight training
programme to develop your specific strength to meet to the demands of your
event/sport.
Strength
training is safe when properly supervised and controlled. Every weight room
should have a set of of rues and regulations pertaining to safety and they
should be on public display. Rules may vary from one weight room to another
but some very basic rules apply to them all:
-
Train only when a qualified coach is present
- Follow your training schedule
-
Work in pairs - one lifting the other spotting
- No horseplay
-
Wear the correct clothing and shoes
-
No eating, drinking or smoking
-
No personal stereos with headphones
-
Help and respect other athletes
-
Only athletes who are working out should be in the weight room
-
Make sure you and your athletes are fully aware of the safety rules applying
to - the weight training room(s) you use.
Weight
training requires supervision to ensure sound technique in pursuit of safety
and efficiency.
One of the misconceptions in the sports world
is that a sportsperson gets in shape by just playing or taking part in his/her
chosen sport. If a stationary level of performance, consistent ability in
executing a few limited skills, is your goal then engaging only in your
sport will keep you there.
However,
if you want the utmost efficiency, consistent improvement, and balanced
abilities sportsmen and women must participate in year round conditioning
programmes. The bottom line in sports conditioning and fitness training
is stress. Not mental stress, but adaptive body stress. Sportsmen and women
must put their bodies under a certain amount of stress to increase physical
capabilities.
Exercise
scientists have identified nine elements that comprise the definition of
fitness. The following lists each of the nine elements and an example of
how they are used:
Strength
- the extent to which muscles can exert force by contracting against resistance
(holding or restraining an object or person)
|
Power
- the ability to exert maximum muscular contraction instantly in an explosive
burst of movements (lumping or sprint starting)
|
Agility
- the ability to perform a series of explosive power movements in rapid
succession in opposing directions (ZigZag running or cutting movements.
|
Balance
- the ability to control the body's position, either stationary (e.g.
a handstand) or while moving (e.g. a gymnastics stunt)
|
Flexibility
- the ability to achieve an extended range of motion without being impeded
by excess tissue, i.e. fat or muscle (Executing a leg split)
|
Local
Muscle Endurance - a single muscle's
ability to perform sustained work (Rowing or cycling)
|
Cardiovascular
Endurance - the heart's ability
to deliver blood to working muscles and their ability to use it (Running
long distances)
|
Strength
Endurance - a muscle's ability
to perform a maximum contracture time after time (Continuous explosive
rebounding through an entire basketball game)
|
Co-ordination
-
the ability to integrate the above listed components so that effective
movements are achieved.
Of
all the nine elements of fitness, strength and cardiac respiratory qualities
are the most important to develop because they enhance all the other components
of the conditioning equation.

Speed
and strength are integral components of fitness found in varying degrees
in virtually all athletic movements. Simply put the combination of speed
and strength is power. For many years coaches and athletes have sought to
improve power in order to enhance performance. Throughout this century and
no doubt long before, jumping, bounding and hopping exercises have been
used in various ways to enhance athletic performance. In recent years this
distinct method of training for power or explosiveness has been termed plyometrics.
Whatever the origins of the word the term is used to describe the method
of training which seeks to enhance the explosive reaction of the individual
through powerful muscular contractions as a result of rapid eccentric contractions.
The
maximum force that a muscle can develop is attained during a rapid eccentric
contraction. However, it should be realized that muscles seldom perform
one type of contraction in isolation during athletic movements. When a concentric
contraction occurs (muscle shortens) immediately following an eccentric
contraction (muscle lengthens) then the force generated can be dramatically
increased. If a muscle is stretched, much of the energy required to stretch
it is lost as heat, but some of this energy can be stored by the elastic
components of the muscle. This stored energy is available to the muscle
only during a subsequent contraction. It is important to realize that this
energy boost is lost if the eccentric contraction is not followed immediately
by a concentric effort. To express this greater force the muscle must contract
within the shortest time possible. This whole process is frequently called
the stretch shortening cycle and is the underlying mechanism of plyometric
training.
The
golden rule of any conditioning programme is specificity. This means that
the movement you perform in training should match, as closely as possible,
the movements encountered during competition. If you are rugby player practicing
for the line-out or a volleyball player interested in increasing vertical
jump height, then drop jumping or box jumping may be the right exercise.
However if you are a javelin thrower aiming for a more explosive launch,
then upper body plyometrics is far more appropriate.
Circuit
training is an excellent way to simultaneously improve mobility and build
strength and stamina. The circuit training format utilizes a group of 6
to 10 strength exercises that are completed one exercise after another.
Each exercise is performed for a specified number of repetitions or for
a prescribed time period before moving on to the next exercise. The exercises
within each circuit are separated by brief, timed rest intervals, and each
circuit is separated by a longer rest period. The total number of circuits
performed during a training session may vary from two to six depending on
your training level (beginner, intermediate, or advanced), your period of
training (preparation or competition) and your training objective.
