Activity and Exercise

Question 1

Physical activity and physical exercise

Answer 1

Physical activity (PA) is any movement produced by skeletal muscles that
results in energy expenditure (e.g., occupational, sports, conditioning, and
household activities). Physical exercise is a subset of PA that is planned,
structured, and repetitive and has a final or an intermediate objective, such
as the improvement or maintenance of physical fitness

Question 2

Isotonic exercises

Answer 2

Isotonic exercises (e.g., walking, swimming,
jogging, and bicycling) cause muscle contraction and change in muscle
length (isotonic contraction)

Question 3

Isometric

exercises

Answer 3

Isometric
exercises (e.g., quadriceps set exercises and contraction of the gluteal muscles) involve tightening or tensing muscles without moving body
parts (isometric contraction).This form of exercise is ideal for patients who
do not tolerate increased activity, such as a patient who is immobilized in
bed

Question 4

Resistive isometric

Answer 4

Resistive isometric exercises are those in which an individual contracts
the muscle while pushing against a stationary object or resisting the
movement of an object. Examples of resistive isometric
exercises are push-ups and hip lifting.
