Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration
I should assume it warming up. You warm up before you play any sport right? Playing sports is exercising.
Hope this helps you!!
Answer:
A, C, D and E
Explanation:
In the assessment of legs, there are many systems that are combined for that part of the body to function optimally.
The reason that all the options are relevant in this question (except for B) specifically referring to legs, is that option B (the cardiovascular system) is not a main indicator of a problem with that part of the body specifically.
If something is wrong with the leg of a patient, there is a small likelihood of it being related to the cardiovascular system, because if the cardiovascular system is causing something to be wrong in the legs, it should not be limited to that section of the body. Hence, the other options are correct, but not option B.
Twisting or pulling a muscle or tendon can result in a strain. It can also be caused by a single instance of improper lifting or by over stressing the back muscles. A chronic strain usually results from overuse involving prolonged, repetitive movement of the muscles and tendons. In addition, there are several factors that put a person at greater risk for a back strain or sprain, including excessively curving the lower back, being overweight, having weak back or abdominal muscles, and tight hamstrings (muscles in the back of the thighs). Playing sports that involve pushing and pulling—such as weightlifting and football—also increases the risk of a low-back injury. Chronic strains happen slowly over time from prolonged, repetitive overuse of muscles. Chronic strains develop from using the same muscle groups in the same pattern, causing even small stresses to build on one another. Causes of chronic strain include:
Improper body mechanics or using the wrong muscle groups for a task, such as repeatedly lifting heavy objects using your back instead of your legs
Improper sports mechanics or techniques, such as habitually gripping a tennis racket too tightly or an incorrect golf swing
Participation in the same exercises in the same way, day after day
Poor posture
Use of the wrong equipment, such as running shoes without the proper support for your foot type
