The increase in lactic acid concentration in the muscle fiber's site doesn't allow the calcium ions flow from the sarcoplasmic reticulum to bind with the troponin of the actin site.Therefore the tropomysin doesn't clear the way from myosin cross-bridges to bind with the troponin which leads to the further muscle contraction.So from that point the entire muscle action ceases, till the lactic acid drains itself to be converted into useful products to be used by the body.But this is only in the case of trained athletes and in case of untrained, sedentary human, the lactic acid concentration takes a leasure-long time to get removed from the site followed by long lasting DOMS (delayed onset of muscle soreness) after any exercise and the opposite action is true in case of trained athletes.

How does the accumulation of lactic acid in muscles contribute to the development of muscle fatigue?
When muscles work hard, they produce lactic acid as a byproduct. The accumulation of lactic acid can lower the pH level in muscles, leading to fatigue. This can interfere with muscle contractions and reduce their ability to generate force, causing muscle fatigue.
What are some exercises that can help strengthen the muscles in the lower back and prevent injuries for individuals who are prone to experiencing lower back pain and issues with their posture, such as the prone y raises?

What are the primary knee extension muscles and how do they contribute to the movement of the knee joint?
The primary knee extension muscles are the quadriceps muscles, which include the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. These muscles work together to straighten the knee joint by contracting and pulling on the patellar tendon, which in turn moves the lower leg forward and extends the knee.
How does the skeletal and muscular systems work together to raise and lower the forearm?
The biceps and triceps muscles work synergistically; the biceps muscles contracting concentrically and the triceps muscles contracting eccentrically when the forearm lifts, and it's the exact reverse when the forearm lowers.
What are the benefits of using a calves machine at the gym for strengthening and toning your lower leg muscles?

What are four reasons to cool down after exercise?
Lactic acid builds up in your muscles when exercising and is being burned off at the same rate. When cooling down lactic acid is still being burned but being produced as a lower rate. If you don't cool down the acid wont break down and will cause your muscles to cramp. I might have left something out, I'm about 90% sure on this answer
