We need to know something about hula hoops first. Viscera? And the anatomy of the thoracoabdominal cavity and the thoracoabdominal wall.
Modern hula hoop appeared in the United States in 1957, which originated from the hula hoop equipment used by native American dances. Because of its strong participation, Xian Yi, old and young, once launched, has been widely loved by people. The manufacturer began mass production in 1958, which made the sport popular in the United States and soon swept the world from the United States. In its heyday, Caron, as one of the major manufacturers, produced 50,000 hula hoops every day to meet the market demand.
But it didn't last long. In the 1980s, people's enthusiasm for this sport gradually cooled down, so that many young people don't even know the existence of hula hoop now. However, related topics are still mentioned and circulated from time to time, such as hula hoop will hurt internal organs and whether hula hoop can help lose weight.
Hula hoop is generally divided into children's diameter of 7 1 cm and adults' diameter of1.02m; At the same time, according to the material and weight, it can be divided into ordinary type and weighted type.
Which muscles participate in hula hoop?
Hula hoops can be placed on the waist, limbs or neck, and the hula hoops can be kept rotating by human strength. Taking the waist-turning hula hoop as the classic mode, people keep turning their hips in one direction, and the trunk of the human body rotates like a spindle with the spine as the axis to maintain the rotation of the hula hoop.
Turning hula hoop involves almost all muscles and joints in the whole body. Hip and spine are the most important and largest range of motion, and the power mainly comes from the movement of trunk and hip muscles.
The main muscles involved in the back are trapezius superficialis, latissimus dorsi, erector spinae and gluteus maximus. The deep layer mainly includes quadratus lumborum, psoas major and psoas minor in the waist, gluteus minimus, iliopsoas muscle and iliopsoas muscle in the waist and buttocks. The muscles in front of the trunk are mainly located in the front side wall of the abdomen, including external oblique muscle, internal oblique muscle, rectus abdominis muscle and transverse abdominal muscle.
Other movements of the neck, lower limbs and upper limbs depend on the corresponding muscle groups in their respective regions. These movements mainly cooperate with the movements of hip joint and spine to keep the balance and coordination of body movements.
Hula hoop is not strenuous exercise.
A woman weighing 50 kg can usually burn about 165 calories by doing hula hoop for 30 minutes, while a man weighing 70 kg can burn about 200 calories for 30 minutes. It is roughly equivalent to swimming or skipping rope at a speed of 40~50 meters per minute, which is equivalent to moderate intensity+aerobic exercise. It can be seen that the intensity of hula hoop exercise is moderate, not strenuous exercise.
On the other hand, from the anatomical and functional relationship, the muscles in the chest and abdomen wall and the organs and tissues in the chest and abdomen are isolated from each other, and the internal organs are protected by the chest and abdomen, which is usually not affected by the muscle movement force and will not cause damage.
Even organs with loose and long mesothelium and ligaments such as stomach and large intestine, as well as ovaries and fallopian tubes, may occasionally cause torsion during strenuous exercise, which is common in all strenuous exercises and not unique to hula hoops.
Another form of visceral injury that people often worry about is visceral ptosis, such as gastroptosis. In fact, the main cause of visceral prolapse is the influence of individual organizational characteristics, such as weak ligaments and fascia, and weak abdominal wall tissue, especially muscle tissue. It has nothing to do with hula hoop and other sports. In fact, hula hoop and other sports can also exercise and strengthen the abdominal wall tissue, which is conducive to preventing and improving organ prolapse.
The above is theoretically speaking, hula hoop rotation will not cause internal organ damage. In fact, by searching the medical literature database, only a few people are related to hula hoop. Visceral damage? Case report. For example, in a case report, a 26-year-old woman with type Kloc-0 diabetes was hospitalized for five days because of high fever and pain in her left waist. Abdominal ultrasound and CT examination found a hematoma around her left kidney. The patient recalled that his only strenuous exercise recently was hula hoop, so he suspected that it might be related to it. In fact, we know that correlation does not mean causality. The patient has 1 type diabetes as the basic disease, so the relationship between perirenal hematoma and hula hoop rotation cannot be determined.
To sum up, no matter in theory or practice, the argument that hula hoop causes visceral injury is untenable.
