<u>Answer</u>:
Squatting to a pet dog before a run will activity create tension in the legs.
<u>Explanation</u>:
Tension in muscle contraction generates tension in the muscle fibers. In natural movements of locomotion the muscle contractions produce changes in length and tension in the muscle fibers of skeletal muscle. The sliding of protein filaments past to each other inside skeletal muscle fiber produces a contraction.
When the muscles is stretched or shortened beyond its normal level a tension which resist the change in the muscle length is felt. Among the above mentioned options the maximum tension can be observed in the following order: squatting to pet a dog > stretching your legs before a run > pressing a car's accelerator pedal > standing for five minutes (no active tension).
