I love the spinning bicycle network online a few days ago, I saw such a report "American Medical Journal: Excessive exercise on spinning bikes will seriously harm the body", specially reprinted to hope that every rider who loves spinning bikes can understand a bit. According to the British "Independent" reported on June 13, medical research shows that although spinning exercise is a very effective fitness method, high-intensity spinning exercise is very dangerous for beginners and may even cause kidney damag
In recent years, the spinning class has been widely welcomed by the public because of its rich and interesting, high calorie consumption and conducive to weight loss in the lower body. However, a new study in the American Journal of Medicine points out that there are health risks in high-intensity spinning courses, especially for fitness beginners, which may cause muscle damage and eventually cause rhabdomyolysis.
Rhabdomyolysis may occur when the human body suffers from severe muscle damage. As the muscle is deprived of oxygen, it decomposes and releases its internal solubles into the human bloodstream (which can lead to serious complications such as kidney failure). Typically, this can happen to victims of severe crush injuries, such as building collapses, falling buildings, or car accidents. However, doctors now point out that for beginners, a high-intensity spinning class can lead to similar consequences.
In general, 50% of patients with rhabdomyolysis do not notice the condition, without any obvious symptoms, and the body will repair itself for a period of time. But those who suffer severe muscle damage during training may experience serious health problems such as yellow urine, muscle aches, dizziness, nausea, and weakness.
According to research data from the American Academy of Family Physicians, common complications of rhabdomyolysis include elevated blood myoglobin levels, or cardiac arrest and renal failure. The first author of the study, Dr. Moline Brogan, a nephrologist from the Westchester Medical Center, pointed out that for safety reasons, the spinning class must be accompanied by detailed guidelines.
Dr. Brogan said in an interview with "Today's Show": "Sports bike is an excellent exercise program, but people should also pay attention to the training intensity when starting a cycling class, and understand the relevant spinning bike attention. Matters. Because during the cycling class, the body's largest muscle group, the quadriceps and gluteus maximus, are simultaneously trained in high-intensity, and exercise safety must be guaranteed."
Personal trainer "Robert Arica" from the Equinox Fitness Center in New York, USA, said he agreed with Dr. Brogan. When asked if the spinning class will cause permanent damage to the human body, Arica said: "In fact, the risk of spinning bike itself is very low, but it also depends on the individual's movement. In comparison, spinning is For a more complicated training course, beginners need to understand the spinning considerations associated with it, and need to warm up before the exercise, instead of starting to step on the spinning bike as soon as they come up."
Fortunately, for most people, especially those who have regular exercise habits, participating in a spinning class does not cause rhabdomyolysis. But for those who do not exercise regularly, but also challenge the physical limits, people who take high-intensity exercises such as spinning courses may cause serious side effects and damage the kidneys.
