Types of Muscle Contraction 3 Different types of muscle contraction that are used in a variety of situations Isometric Eccentric Concentric
Isometrics Isometrics are when there is a muscle contraction, but not change in muscle length Great strengthening tool, used when pain is felt in a ROM Example: Planks, Pushing a wall, wall squat Can exert considerable force on an immovable object, even though not movement occurs
Concentric Most widely known form of muscle contraction During contraction, muscle length shortens to overcome resistance Example: Bicep curl
Eccentric Commonly underutilized muscle strengthening technique Resistance is greater than the muscular force being produced Leads to a lengthening of the muscle while contracting, instead of a shortening Not to say that the weight has to be too heavy to lift
Resistance Training Techniques There are a countless number of ways to improve in strength training Functional Exercises Isometrics Progressive Resistance Exercise Isokinetics Plyometrics
Functional Exercises What does functional mean to you? Functional has to do with “sport specific” exercises Ladder drills LAX stick Football Basketball “Kinetic Chain”
