Answer:
The use of different shoes causes different areas of the skeletal muscles to be activated, if the shoes have a heel or have a greater length in the heel sector, the calf contracts and remains hypertonic.
Explanation:
In addition, it must be considered that the dress shoe has a low impact base, therefore it tends to affect the worker's posture, low back pain and even possible affections in the arch area of the foot.
If we use more heels in the heel sector, the muscular balance is compensated, activating the muscles of the lower limb, mainly the calf and the anterior part of the quadriceps.
Resistance also influences <u>total</u> blood flow. Resistance is defined as the amount of <u>friction</u> the blood experiences as it travels through the blood vessels. Blood flow is always <u>opposed</u> by resistance. Friction is due to the contact between <u>blood</u> and the blood vessel wall. The term <u>peripheral resistance</u> is typically used when discussing the resistance of blood in the blood vessels (as opposed to the resistance of blood in the heart). Several factors affect this friction, including blood <u>viscocity</u> , blood vessel <u>length</u> , and the <u>size of the lumen </u>of blood vessels (as indicated by vessel radius).
