TYPES OF RESISTANCE TRAINING -Isotonic -Isometric -Isokinetic By Belinda Vella
Isotonic Resistance Training
Isotonic resistance training is the most common form of strength training which uses free weights such as dumbbells and barbells.
It is said to occurs when through out the range of movement the weight remains constant.
Isotonic Contractions
Muscle length is said to change during both;
Concentric Contractions
Eccentric Contractions
Concentric Contractions
Isotonic concentric contractions causes shortening in muscle length. Concentric contractions are evident when an individual is moving against the resistance or weight.

Athlete moves the weight or resistance in the same direction to which they are moving. They then pull the weight down faster than it would naturally move with gravity
Isotonic eccentric contractions see the lengthening of muscles occur. Eccentric contractions are evident when an athlete moves in the same direction as the weight or resistance. The passage is then slowed so that movement is slower than it naturally would with gravity.
Sports
Isotonic resistance training is used in the following sports;
Javelin
Squash
Basketball
Rock climbing
50m butterfly
Advantages & Disadvantages
Advantages include;
Easy to do
Overload is easy to administer
Cheap
Can imitate movements specific to a sport
Disadvantages include;
Poor technique can lead to injury
Fatigue occurs
Cannot create the same tension within a muscle
Isometric Resistance Training
Isometric resistance training involve muscular actions in which the length of the muscle does not change and there is no visible movement at the joint.
They occur against an immovable resistance.
Isometric Exercises
Isometric exercises may be completed with sub maximal muscle action. For instance full body exercises that involve sub maximal contractions include;
Plank Bridge Side Bridge Hundred Breaths Exercise
Advantages & Disadvantages
Advantages include;
Cheap, uses no expensive equipment
Relatively few injuries occur in this method
Specific muscle weaknesses can be developed
Disadvantages include;
Develops strengths at one angle only
Time consuming
Isokinetic Resistance Training
Isokinetic resistance training is the newest form of resistance training. Isokinetic resistance training allows a person to operate at a constant speed against a weight or resistance.
This method uses machinery designed to develop strength through a full range of motion.
The harder you push, the harder the machine pushes back.
Isokinetic resistance training allows for the duplication of certain sports movements. For instance; throwing and kicking.
Advantages & Disadvantages
Advantages include;
Resistance can be easily altered
Develops strength through a full range of motion
Strength is developed relatively safely
Disadvantages include;
Machines are expensive
Does not develop ligament and tendon strength as much as isotonic training because the machine provides the stability of the resistance
Injury may occur with inexperienced individuals
