Disadvantages of riding a bike:
First of all, the most controversial injury: "the impact on sex."
Reason: Riding a bicycle will oppress the society, affect local blood circulation, cause discomfort, and even cause prostatitis and "impotence".
Female * * * hyperemia and swelling: Some female patients commute to work by bike for a long time. If the seat is too high, too hard or the handlebar is uncomfortable, their weight will be concentrated on the seat, which will react on the upper urethra and external sphincter through the narrow front end of the seat, causing urinary system congestion, causing dysuria or frequent urination, urgency, or congestion, swelling and other inflammation.
Second, the undisputed injury: the injury of the opponent.
Reason: It is mainly caused by long-term compression of upper limbs during riding, minimal exercise and reduced blood circulation of upper limbs.
Countermeasures: When riding for a long time, you should get off the bus every hour or so to exercise your upper limbs. In addition, strengthen targeted exercises of upper limbs, such as shooting and dumbbells.
Third, injuries that should be paid attention to: cervical and lumbar injuries.
Reason: Mainly riding posture. When a cyclist leans forward excessively (such as riding a sports car), in order to observe the front, he must raise his head and lift his neck. This is a compulsive posture, which will cause tension in the neck muscles. The waist bears the heaviest burden when riding a bike.
Therefore, long-distance riding for a long time may lead to strain of neck muscles and waist muscles.
Countermeasures: When riding for a long time, pay attention to changing the riding posture. The correct riding posture is: the upper body is low and the head leans forward slightly; The arms naturally bend, which is convenient for waist bending, reduces the center of gravity of the body, and prevents the impact force generated by car bumps from spreading to the whole body; Hold your hands lightly and forcefully, and sit firmly on your hips. In order to ensure the correct riding posture, we must do a good job in vehicle selection, seat selection, seat adjustment and handlebar adjustment according to our actual situation.
Fourth, injuries that cannot be ignored: fractures and brain injuries.
Cause: the road is bumpy, the speed is too fast, and the traffic rules are not obeyed.
Riding hard on bumpy roads, bumping up and down, and colliding may all cause coccyx fractures.
When people and cars rush into the road, rampage, run red lights, ride bicycles or ride bicycles in an emergency, cyclists may lose their balance because of nervousness. Coupled with the speed and inertia of the car, he often couldn't stop the car and leaned forward and fell to the ground, causing head injuries.
5. Possible small danger: urinary calculi.
Reason: It is mainly due to excessive sweating when riding, resulting in less urine volume and high concentration of metabolites in urine.
Countermeasures: When you go out to ride, you must bring enough water.
Sixth, the riding posture of bicycles will make you develop bad habits, and teenagers with hunchbacks are the best victims.
