Is it really good to practice abdominal muscles with V-shaped sit-ups?

A article a while ago "Stop doing sit-ups and crunches anymore!"

Many people are starting to ask?

Domestic track and field athletes gymnasts and ball players are doing it. If it hurts the spine, this move should have disappeared long ago!"

First, injuring your spine while sitting ups? (2012 article) mentioned:

Traditional sit-ups (Sit-ups) produces at least 3350 Newtons of compression force on the spine, which is a great pressure on the lower back. The National Institute of Occupational Safety and Health (USNIOSH) declares that the compression force of more than 3000 Newtons is unsafe for the human body.

The study also pointed out that the effect of sit-ups is no different from the movements that use stability to train core movements. International Firefighters Association (International Association of.Fire Fighters accepted the research results, removed the sit-up fitness test items and agreed to replace them with plank support.

In addition, the research also included sit-ups and back-friendly core stabilization. Exercises) For comparison, including bird-dog-style movements, there is no difference in the effects of the two types. In fact, those who have done core movements have made significant progress in the military sit-up test.

Is "Core stable movements that are more friendly to the lower back" so important?

Are you supposed to think about this question: "How many athletes have problems with back discomfort or pain? Or, how many people have problems with back pain?"

If the public or athlete has long-term tightness, discomfort or pain in the lower back (lumbar spine), they are training Shouldn't you give too much pressure to these areas during practice? Or should you change the training method?

Once discomfort/pain occurs, the body instinctively avoids these areas and completes the movements through other or compensatory methods. Is it possible to cause sports injuries in other parts?

The above problems are not only used for sit-ups or changes, but also for any movement, such as: back squat lift. Squat: The movement itself is not dangerous, and it is dangerous to be unprepared.
