Question

susan and laura are having a disagreement over who has more muscular strength. susan is a distance runner and laura is a sprinter. which girl would be more likely to have more muscular strength?
a. susan because her muscles can contract repeatedly over a longer period of time.
b. laura because her muscles can produce more force for a single event.
c. laura because her muscles can remain contracted over a longer period of time.
d. susan because her muscles work together to produce great force to take her the distance.
when comparing a well - designed muscular strength workout to a well - designed muscular endurance workout, you would conclude that __________.
a. fewer repetitions with heavier weights would build muscular strength, while less weight and more repetitions would build muscular endurance
b. more weight and more repetitions build strength, while less weight and fewer repetitions build endurance
c. moderate weight with high repetitions builds strength, while heavy weight with low repetitions builds endurance
d. less weight with low repetitions builds strength, and moderate weight with low repetitions builds endurance
select the statement that accurately describes the muscular system.
a. the muscular system is composed of two different types of muscles.
b. the muscular system is composed of muscles, tendons, and ligaments.
c. the muscular system is responsible for controlling the actions of smooth and cardiac muscles.
how can tight muscles result in back pain?
a. they contain sensitive nerves that become painful when tight.
b. they can constrict the nerves in the spinal column.
c. tight muscles stretch surrounding tissues and organs.
d. they improve posture, which results in back pain.
a goniometer measures __________.
a. a joints maximum range of motion
b. a joints minimum range of motion
c. a joints flexion
d. extension and hyperextension
which statement best describes the factors that affect muscular endurance?
a. size of the muscle cells, ability to store fuel, and blood supply to the muscles
b. number of muscles, amount of exercise, and type of person
c. level of flexibility, amount of exercise, and ability to store fuel
d. blood supply to the muscle, type of exercise, and type of muscle cells
w might being too strong actually restrict a joints range of motion?

Explanation:

• First question: Sprinters (Laura) focus on producing maximum force for a short - term, single - event (like a 100 - meter dash), which is related to muscular strength. Distance runners (Susan) focus on muscular endurance (contracting repeatedly over time). So, Laura has more muscular strength because her muscles can produce more force for a single event.
• Second question: Muscular strength workouts typically use fewer repetitions with heavier weights to build strength. Muscular endurance workouts use more repetitions with less weight.
• Third question: The muscular system is composed of three types of muscles (skeletal, smooth, cardiac), not two. It is not composed of ligaments. The nervous system controls smooth and cardiac muscles. The muscular system is composed of muscles, tendons (connect muscle to bone).
• Fourth question: Tight muscles can constrict nerves in the spinal column, leading to back pain. Muscles are not inherently sensitive in a way that just being tight causes pain (A is wrong). Tight muscles don't stretch surrounding tissues and organs in a way that causes back pain (C is wrong). Tight muscles usually don't improve posture (D is wrong).
• Fifth question: A goniometer is a device that measures a joint's maximum range of motion. It is not for minimum range (B), just flexion (C) or just extension and hyperextension (D).
• Sixth question: Muscular endurance is affected by the size of muscle cells (more mitochondria in endurance - trained cells), ability to store fuel (glycogen), and blood supply (to deliver oxygen). The number of muscles (B), level of flexibility (C), and type of exercise (D - type of exercise affects but not as comprehensively as A) are not the best descriptors.

Answer:

1. B. Laura because her muscles can produce more force for a single event.
2. A. fewer repetitions with heavier weights would build muscular strength, while less weight and more repetitions would build muscular endurance
3. None of the options A, B, C are correct. The muscular system is composed of muscles and tendons. (If we assume there is a typo and the intended correct option is not present, but based on the given options, there is an error in the question's options)
4. B. They can constrict the nerves in the spinal column.
5. A. a joint's maximum range of motion
6. A. size of the muscle cells, ability to store fuel, and blood supply to the muscles
