Why are sit-ups unscientific?

　　Sit-ups are a well-known fitness exercise, but in fact it is not scientific and has many hidden dangers. The following is a detailed analysis for everyone from multiple aspects.

Easy to cause lumbar disc herniation and spinal injury

　　Increased disc pressure: During sit-ups, the spine will bear greater pressure, especially the lumbar spine. Repeated bending movements will cause excessive compression of the intervertebral disc, increasing the risk of disc degeneration and annulus fibrosus rupture, thereby causing lumbar disc herniation.

　　Destroy the physiological curvature of the spine: Under normal circumstances, the spine has a natural physiological curvature. When doing sit-ups, the curvature of the spine will change. This will destroy the stability of the spine in the long term, lead to spinal injury, and may also cause chronic low back pain。

Causing muscle compensation problems

　　Iliopsoas muscle compensation: When many people do sit-ups, due to irregular movements, they over-rely on the iliopsoas muscles instead of the abdominal muscles. Not only is this ineffective exercise Abdominal muscles can also lead to overdevelopment of the iliopsoas muscles, further increasing the burden on the spine.

　　Other muscle compensation: In addition to the iliopsoas, muscles in the neck, shoulders and other parts of the body may also participate in compensation. This will over-fatigue the muscles in these areas, increase the risk of sports injuries, and also affect the effectiveness of core muscle exercises.

Not consistent with exercise physiology principles

　　Lack of dynamic stability training: Sit-ups are mainly a single flexion and extension movement and lack training on the dynamic stability of the body. In daily life and sports, we need more dynamic core stability, and sit-ups cannot meet this need.

　　Not conducive to nerve conduction and metabolic activation: Scientific exercise should be able to promote nerve conduction and metabolic activation. The action pattern of sit-ups is relatively simple and cannot fully activate the nervous system and metabolic system of the body, which is harmful to the overall body. healthy The promotion effect is limited.

There are biomechanical risks and contraindications for rehabilitation medicine

　　biomechanical risks: From a biomechanical perspective, sit-ups will produce large shear forces and cause damage to the microstructure of the spine. This damage may not be noticeable in the short term, but long-term accumulation can have serious consequences for spinal health.

　　Rehabilitation medicine contraindications: For people who already have lumbar vertebrae disease For people with cervical spondylosis, cervical spondylosis, etc., sit-ups are a taboo movement in rehabilitation medicine. Performing sit-ups may aggravate the condition and be detrimental to recovery.

There are better alternative sports

　　Core training moves: You can choose some more scientific core training movements, such as plank support, abdominal muscle anti-torsion, etc. These movements can better exercise the core muscles, improve core stability, and reduce pressure on the spine.

　　functional training: Functional training emphasizes the overall movement and coordination of the body and can better simulate movement patterns in daily life and sports. Compared with sit-ups, functional training is more practical and safer.

　　In the process of fitness, choosing the right exercise method is crucial. Understanding the disadvantages of sit-ups can allow us to better protect the body and avoid sports injuries.
