Topic Test Stretching

A. concentrating your stretching on your legs and back

B. They can constrict the nerves in the spinal column.

C. targeting a particular area for improvement

C. trunk life

Stiff and tight muscles can constrict nerves in the back. When these nerves are constricted, it can result in sensations of pain throughout the back, especially the lower back.

A. frequency, intensity, time, and type

D. ten and twenty minutes

Stretching a muscle slowly prevents it from overextending and being damaged. When stretches occur too quickly, such as with bouncing, the muscle can be seriously damaged during the uncontrolled motions.

Static is holding usually 30-60 seconds per stretch. Best way to increase your flexibility. Dynamic is movement based to loosen up joint.

Static flexibility tests are more common than dynamic tests because they are easier to replicate. It is difficult to standardize motion-based tests between different subjects, while static tests are simple and easy to standardize because the metrics are fixed and not open to interpretation.

Both types of hurdle stretches loosen up the hamstring in the same way. But the hurdle stretch with the leg pointed back puts sideways torque on the back knee and can result in injury. So while the potential benefit of the exercises are the same, one risks serious injury to the knee.

B. Resting between workouts helps to prevent injuries.

All of these activities involve assuming and holding precise forms and positions. Holding these controlled positions requires a level of static flexibility beyond that required by everyday activities.

Both progression and overload are concerned with slowly increasing the intensity and challenge of the exercises of a workout. Overload arises from the need to increase exercise intensity to maintain a challenging workout: as a body adapts to a given exercise level, the difficulty must be increased to keep challenging the body and making progress. Progression is closely related to overload and also requires that an exercise program gradually become more difficult. Progression, however, is focused on the increased goals of an exercise program rather than the adaptation of the human body.

B. Age, gender, and joint structure cannot be changed.
