Isotonic concentric Isotonic concentric contractions causes contractions causes shortening in muscle shortening in muscle length. Concentric length. Concentric contractions are evident contractions are evident when an individual is when an individual is moving against the moving against the resistance or weight.resistance or weight.

Athlete moves the Athlete moves the weight or resistance in weight or resistance in the same direction to the same direction to which they are which they are moving. They then moving. They then pull the weight down pull the weight down faster than it would faster than it would naturally move with naturally move with gravitygravity

contractions see the contractions see the lengthening of muscles lengthening of muscles occur. Eccentric contractions occur. Eccentric contractions are evident when an athlete are evident when an athlete moves in the same direction moves in the same direction as the weight or resistance. as the weight or resistance. The passage is then slowed The passage is then slowed so that movement is slower so that movement is slower than it naturally would with than it naturally would with gravity. gravity.

Isometric Resistance TrainingIsometric Resistance Training
Isometric resistance training Isometric resistance training involve muscular involve muscular actions in which the length of the muscle does actions in which the length of the muscle does not change and there is no visible movement at not change and there is no visible movement at the joint.the joint.
They occur against an immovable resistance. They occur against an immovable resistance.
Isometric ExercisesIsometric Exercises
Isometric exercises may be completed with Isometric exercises may be completed with sub maximal muscle action. For instance full sub maximal muscle action. For instance full body exercises that involve sub maximal body exercises that involve sub maximal contractions include; contractions include;
Plank Bridge Side Bridge Hundred Breaths Exercise

Disadvantages include;Disadvantages include; Develops strengths at one angle onlyDevelops strengths at one angle only Time consumingTime consuming
Isokinetic Resistance TrainingIsokinetic Resistance Training
Isokinetic resistance training is the newest Isokinetic resistance training is the newest form of resistance training. Isokinetic form of resistance training. Isokinetic resistance training allows a person to operate resistance training allows a person to operate at a constant speed against a weight or at a constant speed against a weight or resistance. resistance.
This method uses machinery designed to This method uses machinery designed to develop strength through a full range of develop strength through a full range of motion. motion.
The harder you push, the harder the machine pushes The harder you push, the harder the machine pushes back.back.
Isokinetic resistance training allows for the Isokinetic resistance training allows for the duplication of certain sports movements. For duplication of certain sports movements. For instance; throwing and kicking. instance; throwing and kicking.
