Turning hula hoop can consume about 5 calories per kilogram per hour. Taking a weight of 45 kg as an example, you can consume about 45 (kg) *5 calories =225 calories per hour. But it is best not to turn the hula hoop for more than half an hour every day, otherwise it may lead to visceral displacement. There are reminders on some regular hula hoop packaging bags, just like there are "smoking is harmful to health" on cigarette cases. Hula hoop used to be a popular fitness method. Adults and children love it. I don't know when hula hoop has become a way for ladies to lose weight, especially some middle-aged women, who have fat on their waist and abdomen, shake it downstairs or in the park for a while after dinner every day, trying to lose weight by shaking hula hoop. But fitness experts suggest that shaking the hula hoop can't help you lose weight, but it will hurt you after a long time. Hula-hoop shaking is a simple waist exercise, and the amount of exercise is very small. It is not realistic to achieve slimming effect by this exercise alone. Losing weight does not mean that you are not fat when you move, but you need to exercise all over your body to consume fat. Only by extending the exercise time and continuing to exercise can we finally consume body fat. Short-term exercise belongs to anaerobic exercise, which will only lead to muscle soreness and will not consume fat. The hula hoop twists and swings just at the junction of thoracolumbar vertebrae. When the spine is excessively twisted or the abdominal pressure suddenly increases, it may lead to the sudden change of the pressure in the spinal canal, which may lead to the rupture of blood vessels and excessive torsion of the waist, which may easily lead to lumbar muscle strain, lumbar facet joint hyperplasia and lumbar disc herniation. Fitness experts believe that it is not impossible to use hula hoop as a leisure sport. However, it is necessary to shake the hula hoop scientifically, otherwise it will be counterproductive. The first thing to note is that the exercise time should not be too long. The best continuous exercise time for normal adults is 15~20 minutes. Hula hoop should not be too heavy, the size should not be too big, and the weight is probably the degree that the index finger and middle finger can bear the weight; People with lumbar muscle strain, spinal injury and osteoporosis are not suitable for this sport. The best fat-reducing exercise is aerobic exercise, which should last for 30 ~ 50 minutes, such as swimming, running and cycling.
