Explain why head circles and arm circles are considered dangerous exercises.
Head circles can strain or injure the neck by rotating it through an excessive range, and arm circles can overstress the shoulder joint and cause injury.
Why should you allow a minimum of 24 hours of rest between intense stretching activities?
A minimum of 24 hours allows the muscles and connective tissues to recover and repair, reducing soreness and the risk of overuse injuries.
Compare and contrast static and dynamic flexibility.
Static flexibility is the ability to hold a stretch or position without moving. Dynamic flexibility is the ability to move a joint through its range of motion during active movement. Both describe range of motion, but static flexibility is measured while still and dynamic flexibility while moving.
Why do activities like yoga, ballet, and gymnastics require better than normal flexibility?
Yoga, ballet, and gymnastics require better-than-normal flexibility because they involve large ranges of motion, extended body positions, and controlled movements that ordinary daily activities usually do not require.
Compare and contrast the exercise principles of progression and overload.
Overload means placing greater-than-normal demands on the body during exercise. Progression means gradually increasing the overload over time—for example, by adding weight, repetitions, duration, or intensity—as fitness improves.
Explain what is meant by balance stretching.
Balance stretching means stretching both sides of the body and opposing muscle groups evenly, rather than stretching one side or muscle group much more than the other.
Explain why regular exercise is the best way to prevent flexibility issues.
Regular exercise helps maintain flexibility by moving the joints through their ranges of motion, reducing muscle tightness, and keeping the muscles strong enough to support normal movement.
How can stiff and tight muscles result in back pain?
Stiff and tight muscles can pull the pelvis and spine out of proper alignment, limit normal movement, and place extra strain on the back muscles and joints, which can result in back pain.
