The hidden danger of cycling: the influence on fertility
The reason is that riding a bicycle will oppress * * *, affect blood circulation, and seriously cause diseases such as prostatitis.
Male fertility
Many men who ride bicycles will feel pain, heaviness, defecation, numbness, urgency and discomfort after riding.
The reason for these discomforts is that riding a bicycle is due to the compression of the prostate, which leads to congestion and swelling. Improper saddle can also lead to male diseases.
Many women don't pay attention to the height of the seat when riding a bicycle, which makes the weight excessively concentrated on the seat.
Female hyperemia and swelling
Some female patients commute to work by bike for a long time. If the seat is too high or too hard or the handlebar is uncomfortable, their weight will be concentrated on the seat, pressing the upper urethra and external sphincter, causing congestion in the urinary system, causing dysuria or frequent and urgent urination. Or cause inflammation such as congestion and swelling.
Countermeasures
1. Choose the right car.
When choosing a bike, you must choose the right bike according to your height, weight and even body proportion. You can also adjust your bike according to your own situation. In a word, you should make your bike serve you and become an active member in your healthy and fashionable life.
2. Select and adjust the car seat
If the seat is too high and the cyclist is short, it will not only cause discomfort during exercise, but also cause uncoordinated movements and bring discomfort to the seat. Therefore, it is necessary to pay attention to selecting the appropriate cushion and adjusting the height of the cushion.
The hidden danger of cycling: the injury of opponents
The main reason is that the upper limbs are compressed for a long time, the exercise is very small, and the blood circulation of the upper limbs decreases during riding.
Many people will feel numbness and pain in their hands after riding bicycles for a long time, and even writing with pens and eating with chopsticks will be affected. Doctors call this condition carpal tunnel syndrome.
There is a foot carpal tunnel at the junction of wrist joint and palm, which is composed of pea-sized pisiform bone and fibers. The ulnar nerve passes through the tunnel and distributes to the ulnar side of the hand.
When riding a bicycle, if you hold the handlebar tightly with both hands and the ulnar side of your palm touches the handlebar, pisiform bone will get stuck in it. When pedaling uphill or against the wind, accelerating or leaning forward, the wrist joint will inevitably stretch back excessively, which will stretch the ulnar nerve; At the same time, the supporting force of the upper limb increases, and the pressure in the ulnar carpal tunnel also increases, thus causing the above symptoms.
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.
Hidden danger of cycling: injury to cervical spine and lumbar spine
The main reason is 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, which is a compulsive behavior and 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, you should pay attention to changing your 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.
Hidden dangers of cycling: fracture and brain injury
The reason is that 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.
The hidden danger of cycling: urinary calculi
The main reason is that after sweating a lot when riding, the urine volume is small and the concentration of metabolites in urine is too high.
Countermeasures
When you go out for a ride, be sure to bring enough water.
The hidden danger of cycling: forming bad habits
Although riding a bicycle does have some disadvantages, we should mainly pay attention to the riding posture and be prepared for long-distance riding, so we don't have to worry too much about the harm of riding a bicycle.
Correct riding posture
1, cushion angle
Generally, the cushion needs to be installed horizontally, or the front end is slightly lower, but try not to tilt the front end.
Some people often complain about hip pain after riding a bicycle, which may be caused by excessive pressure on PP or the inner thigh at the front end of the seat cushion. At this time, you need to check whether your seat cushion is horizontal or not, and even adjust the nose of the seat cushion slightly downward, which can reduce the wear on the crotch.
Another effective way to reduce wear is to put on padded cycling pants.
2. Cushion height
If the height of the cushion is not appropriate, there will be knee pain after long-distance riding, and many times the injury of the human knee can not be recovered. The doctor can only help you prevent the disease from getting worse. It is necessary to pay attention to the setting of the height of the cushion, so that maintaining the correct posture will not damage the joints.
In my experience, the most suitable height of a car seat, when the pedal reaches the lowest point, the legs can be easily straightened and the knees can be bent, but when the legs are slightly straightened, the knees can be slightly bent, so that blood can pass through the knees during riding.
Of course, if you are not used to new bicycles and adjusting the seat cushion too high, you can lower it first and then raise it slowly, and safety is the first.
3, back, neck posture
When riding, the back needs to be straight, but not vertical. You should lean forward and stand upright. You should lean forward from your hips, not from your waist or back chest. Otherwise, you will become a Luo Guo or a shrimp, not only to look good, but also to keep your spine as straight as possible. Otherwise, riding for a long time will make your back uncomfortable.
Keep your neck naturally straight, not too low or too stiff, or your neck will ache-if you feel your neck is low and your head is drooping, you need to rest, so go and rest as soon as possible.
Bicycle is an indispensable tool for green travel, so while riding, look at what needs attention, so as to avoid it, ride healthily and keep healthy.
Bicycle equipment
Cycling suit
Its function is to help you sweat and make your body feel dry. Judging from summer clothes, they are generally composed of short-sleeved shirts and shorts similar to T-shirts. Most of the materials are polyester * * * polyester * *, and there are also some patented materials of big companies.
For example, Lycra * * * Lycra * * and COOLMAX of DuPont Company in the United States. Clothes are mostly tight-fitting in order to reduce wind resistance and rub the bike. When riding, the front of the coat is shorter than the back, and there will be three storage pockets at the back, which can store light items, which is very convenient.
You can pick up and put things freely by hand during riding. Shorts will have padded crotch to increase riding comfort.
Kettle for boiling water
This is necessary. Water is the source of life. How can it be missing? The average kettle has a capacity of 600,750,900 ml. It would be great if you could install two kettles on your bike.
The design of the spout is also specially prepared for riding, which can ensure that it is convenient for you to take out the kettle and drink water when riding, as long as one hand cooperates with the spout. Remember! Don't block your sight by drinking water while riding.
eyeglasses
Bicycle glasses must meet the requirements of ultraviolet protection, unbreakable, good ventilation and face-fitting design. Ultraviolet protection is generally the standard UV400, and unbreakable means that it will not hurt the human body when it is hit. Good ventilation is to keep the line of sight clear, and the face-to-face design is to prevent foreign objects from entering the eyes.
gloves
Improve the comfort of the hands when riding, and protect the hands when falling off the car. With short fingers in summer, you can control your bike better.
Additional weight bag
The necessary tools mentioned above can be put in the air pump. Of course, if the bag has enough capacity, it can also hold other items. Those who have seen it will see:
