Question

what is the difference between active and passive insufficiency with explanation and example

Answer 1

assive Insufficiency

Passive insufficiency occurs when the muscle fails to extend far enough. This happens since a full stretch at multiple joints cannot occur. This position is the longest possible length of a muscle.

The muscle can generate hardly any active tension, the tension created when your muscle contracts, while remaining in this position since the contraction sites place too far apart. It does generate great passive tension though, which results from the stretching of the tissue.

Anytime you feel a deep stretch in the muscles, such when reaching to touch your toes, you experience passive insufficiency. Improving flexibility through stretching often places muscles in passive insufficiency, though with more control than you would have under a heavy load.

Active Insufficiency

Active insufficiency occurs when the muscle fails to shorten enough. You may feel this as a cramping sensation because the muscle bunches up like a ball of yarn. This is the shortest possible length of a muscle.

The excessive overlap of the potential contraction sites will result in little active or passive tension.

Flex your wrist completely. Your palm should approach the soft belly of your forearm. Attempt to tighten your fist. You will notice that it feels impossible it to close your fist fully or with much force compared to closing your hand in a slightly extended position, as happens when normally grasping an object.

Answer 2

Answer:

Passive insufficiency;

takes place when a muscle does not stretch as required .It normally occurs as a result of limitation from the joints  this is the longest a muscle stretch can go.

muscles find it hard to regenerate, When your muscles contract , while remaining in the same  position it prompts the muscles  to generate active tension which is a result of stretching tissues.

Active Insufficiency;

Takes place at the point when the muscles refuse to  shorten . They depict their shortest size and can cause muscle cramps .
