Q

three overarching types of muscle actions:

A

  2. isometric: Muscle tension is created without a change in muscle length and no visible movement of the joint.
  3. isokinetic: The speed of movement is fixed, and resistance varies with the force exerted. It requires sophisticated training equipment often seen in rehabilitation or exercise physiology laboratories
51
Q

Isotonic muscle action

Q

global muscles can be categorized into subsystems, which include

  2. posterior oblique (POS): latissimus dorsi, thoracolumbar fascia (connective tissue of the low-back), and contralateral gluteus maximus.
  3. anterior oblique (AOS): similar to the POS, just on the anterior side of the body - obliques, the adductor (inner) thigh muscles, and the hip external rotators
  4. lateral subsystem: (LS) is made up of the lateral hip (gluteus medius) and medial thigh muscles (adductors) and the contralateral quadratus lumborum, all of which provide movement in the frontal plane
85
Q

classifications of levers

A
  1. first: have the fulcrum in the middle, like a seesaw. Nodding the head is an example of a first-class lever, with the top of the spinal column as the fulcrum (Levangie et al., 2019).
  2. second: resistance in the middle with the fulcrum and effort on either side, similar to a load in a wheelbarrow where the axle and wheel are the fulcrum points. The body acts as a second-class lever when one engages in a full-body push-up or calf raise
  3. third class: effort placed between the resistance and the fulcrum. The effort always travels a shorter distance and must be greater than the resistance. Most limbs of the human body operate as third-class levers. An example of a third-class lever is the human forearm; the fulcrum is the elbow, the effort is applied by the biceps brachii muscle, and the load is in the hand
