Answer:
When the body is stressed, muscles tense up. Muscle tension is almost a reflex reaction to stress—the body’s way of guarding against injury and pain.
With sudden onset stress, the muscles tense up all at once, and then release their tension when the stress passes. Chronic stress causes the muscles in the body to be in a more or less constant state of guardedness. When muscles are taut and tense for long periods of time, this may trigger other reactions of the body and even promote stress-related disorders.
Explanation:
For example, both tension-type headache and migraine headache are associated with chronic muscle tension in the area of the shoulders, neck and head. Musculoskeletal pain in the low back and upper extremities has also been linked to stress, especially job stress.

prevents the cause of injuries, reducing muscle strain and improve muscle
performance. The answer is letter D. The goal of warming up is to increase body

your muscles, and brings fluids to your joints. It will improve the performance
in exercising by actively moving the joints and increase in muscular
performance at the same time eliminating injuries along the way. </span>
