Not inherently, no. Stretching a muscle means that the muscle is lengthening, it is stretching from a given position of shortness.
Muscles CAN tear during a stretch, this is certainly a risk. This depends on a lot of factors, like how far it is being stretched, the amount of passive tension in the muscle, the amount of active tension, the speed of the stretch, the amount of external force (if any) being used, the stability, the joint alignment, etc.
stretching cant prevent micro tears, but it can help in repairing them. for the bests results, do an aerobic activity first to get your blood flowing, then stretch to allow the blood to fill the micro tears. sourness is also caused by the swelling of the muscles caused by the micro tears. stretching also helps this.
When a muscle is pushed to far with exertion, small tears can occur in the muscle tissue. The pain associated with this damage when the muscle is used is called a pulled muscle.
When one tears it muscles while working out in the gym or carrying something heavy, the muscle tissue will break. After it breaks, muscle tissue will slowly repair, piece by piece. And thus, after a day or two, the muscle will recover, if not, see a doctor. ATTENTION: IT CAN BE DANGEROUS.
When you do excessive work, your muscles can become strained beyond their limits. This causes very tiny tears in the muscle tissues. (This is why you feel sore after a workout.) When your body is given time to heal, the torn tissue is mended with more muscle tissue. This is what causes an increase in muscle mass.
Going from 14ga to 8ga is actually skipping two sizes, 12ga and 10ga. Skipping sizes when stretching is always a bad idea, no matter what piercing. So to answer your question, no its not okay to skip sizes when stretching your septum. It can cause blowouts or tears. Tears create a risk of infection and can lead to scar tissue that prevents stretching down the line. Good luck stretching :)
micro tears in muscle fibres
Tears aren't just made out of water, they are made from tear film and a microscopically three-layered structure.
If this lump showed up all of a sudden during vigorous activities like sports, you have likely strained a muscle. A strained muscle by definition is microscopic tears in the muscle tissue. These are graded I, II, III, or IV. Grade I is minor and with a little rest will heal on its own in a week or two. Grade II is a little more torn tissue, with more pain, requiring at least two weeks of resting, icing, and gentle stretching to heal. A lump in the muscle can appear as a secondary muscle spasm. Grade III is a large amount of the muscle torn. It is very painful even, at rest, and usually develops a lump or dent in the muscle body from the torn tissue. Grade IV is a complete muscle tear which oddly, after it tears usually is not painful. There is always a definite lump of muscle near its attachment because it is no longer held at both ends of the muscle. Depending on which muscle is torn, it is often aided to heal but not surgically repaired. I almost forgot..... If the lump came about over a longer period of time, like weeks or months, have it checked by a doctor.
"Dynamic" means that you are in motion while you perform the exercise. An example of dynamic stretching would be putting your toes on the edge of a step and bouncing as your heels drop below the edge. This would stretch the gastrocnemius. Dynamic stretching can be dangerous because it can lead to muscle tears and other injuries if done improperly so you should learn proper stretching techniques from a qualified trainer.
Static stretching (stationary stretches) is important after exercise to prevent cramping and tightness in muscles that can develop into muscle tears and strains later on. Before exercise static stretching should be kept to a minimum as it limits power from the muscles. Dynamic stretches should be used before exercise to prevent injury and properly warm up the body. Generally stretching is important because it prevents injury during and after exercise.
It breaks down the nerve system. Then it tears apart tissue, muscle and your body won't be regulated very well from the brain. So heart shuts off.
The destruction of the micro-filaments (actin, myosin) in a muscle cell that enable it to contract. The destruction of these filaments prevent the function of that muscle cell. A large amount of micro tears in a large amount of muscle cells contributes to the soreness present during weight training and is what triggers the body into producing stronger muscles.
