Complete tetanus
Lactic acid builds up and causes muscle burn.
The biceps muscle relaxes!!!!!=)
Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same. Although the term contraction implies shortening, when referring to the muscular system, it means muscle fibers generating tension with the help of motor neurons (the terms twitch tension, twitch force, and fiber contraction are also used).
Charley horse is a type of muscle spasm that typically occurs in the leg. The muscle spasm causes the muscle to contract by itself and it cannot be relaxed normally.
Anaerobic respiration occurs whenever oxygen can't be delivered to the muscle when it needs to contract.

Sudden pain that occurs in the calf muscle during activity may be the result of a pulled or torn calf muscle. This is called a calf strain or a calf pull. It occurs when part of the muscles of the lower leg (gastrocnemius or soleus) are stretched beyond their ability to withstand the tension. This stretching can result in small microtears to the muscle fibers or, in a severe injury, a complete rupture of the muscle fibers.
In rugby when you are pushing against each other( in a rugby scrum) your muscles contract but stay the same length and this is isometric contraction. Even though you are using a lot of force your muscles stay the same length.
Rock tension is stress that occurs when forces act to stretch an object. Tension occurs at divergent play boundaries, when two tectonic plates pull away from each other.
Not sure but I think this person may be looking for the gastrocnemius muscle it is situated in the calf of your leg Sudden pain that occurs in the calf muscle during activity may be the result of a pulled or torn calf muscle. This is called a calf strain or a calf pull. It occurs when part of the muscles of the lower leg (gastrocnemius or soleus) are stretched beyond their ability to withstand the tension. This stretching can result in small microtears to the muscle fibers or, in a severe injury, a complete rupture of the muscle fibers, and when this happens you will be in no doubt due to the pain
The electrical impulse reaches all the muscle tissue in the ventricles, and the ventricles contract. This electrical conduction pattern occurs approx. every 0.8 seconds.
