Total muscle weakness isotonic isometric isokinestic

Total muscle weakness always the same?!

1. Total muscle weakness different for the types of muscle activation

Because there are different types of muscle exercise, I think you also have to make a difference in experienced total muscle weakness.

  • Isotonic: Isotonic contraction is the force generated by a muscle while contracting, when the muscle lengthens and shortens during movement, with the force remaining constant. Therefore, when picking up a glass to take a drink your muscles would use the same force throughout the movement up and down, which is nearly impossible. During normal muscle contraction the force varies throughout the movement. A more accurate term is dynamic contraction, meaning the muscle tension varies as it moves the glass. (…) [Read more]
  • Isometric: If you push against something that is immovable you are experiencing isometric contractions. This may also be called static tension. Isometric exercise involves muscle contraction without the muscle or joints moving. (…) [Read more]
  • Isokinetic: Isokinetic exercises are used in therapeutic settings. Using a dynamometer to control the contraction, isokinetic exercise helps build strength in stroke victims or people who have limited used of their muscles. An isokinetic contraction is a dynamic contraction, but the speed of the entire movement is controlled by the machine. (…)  [Read more]

2. Total muscle weakness with respect to isotonic, isometric and isokinestic muscle activation

  • At Specialized Kinesiology we use ISOTONIC muscle testing. Total muscle weakness experienced while performing this test often times is easy to correct. For anchoring the correction for total muscle weakness it may be required to perform a timeline correction. The person is passive in this action.
  • I wonder if you can experience total muscle weakness while performing Isometric excercise?
  • I can imagine total muscle weakness while performing Isokinetic excercise is something totally different in experience. I can imagine it feels like having “no power” at all. This is because the force is controlled by the person himself.
