Cyclist injuries and worries

Print Article


The bike is seeking your body and improves your health. But sometimes it overwork your body or cause injury. "Cyclo health" and sports doctor help you make the point for not only enjoy the benefits of cycling.

Most often, pedal causes a healthy physical stimulation which causes a beneficial adaptation to your shape. However, excessive stress becomes aggression and can cause damage. Your heart, especially put to use, may be the victim of a failure! Your joints, tirelessly repeating the same movement, start from time to time to suffer! Even your bones may break during a fall! Let's try to understand each of these concerns to avoid or cure.

The discomfort

If suddenly very tired over you, so feel your head spinning, you are the victim of a malaise! Your heart can not pump enough blood to your head and your brain lack of oxygen. This inability of the heart is sometimes triggered a succession of irregular and ineffective heartbeats caused by severe heart disease! When this symptom occurs just stopped effort, it can be a "vagal malaise" more Benin: the heart abruptly slows while the blood vessels leading to the legs remain largely open. The blood rushes ejected less powerfully in the lower limbs at the expense of your brain! You are on the verge of fainting! Spontaneously, you lie ... and the blood returns to your skull, you recover gradually. In practice, any discomfort is serious until proven otherwise! Any discomfort imposes a medical examination! If your doctor confirms that it is a vasovagal reaction, you take care to eat properly throughout your ride. You will put a point of honor to train regularly. Above all, you will not stop abruptly, especially after strenuous exercise! At the end of exit, you program a "return to calm" during which you will slow down gradually for at least 5 to 10 minutes.


If you have a headache during or after exercise several origins can be considered. Hypertension is the first case to evoke especially if you "feel type in your head to the rhythm of your heartbeat." A medical evaluation is essential to avoid the rupture of a small vessel of the brain! If your pain is localized over an eye, it may be sinusitis. In winter, cold air enters the airways and irritate these cavities slightly infected. Take care of your sinusitis and protecting the roll down your face with a scarf or mask. If you suffer after your workout, it might be a real headache favored by fatigue. From the beginning of the crisis, take a traditional pain medication. Next time, reduce the duration and intensity of your workout. Feel free to discuss this with your doctor especially if your symptoms are resistant to such good advice!

The scaphoid fracture

On the occasion a small fall on the hand, you risk a scaphoid fracture. Be very careful because this lesion is not very painful and can be confused with a simple wrist sprain. Unfortunately, in the absence of rigorous treatment, the scaphoid does not consolidate correctly and wrist spoils very quickly. A few years later, your articulation makes you suffer and becomes steeper. Indeed, the scaphoid is a small bone vital to the proper functioning of the wrist. In the manner of a puzzle, the hand is made up of many small tightened and stabilized by the scaphoid bone. If it is not consolidated, the puzzle falls apart at the slightest movement and unwanted friction wear irremediably the joint. After a fall on the hand and wrist pain, it is essential to consult your doctor. Usually simple radiographs allow for the diagnosis of the fracture. In these circumstances, a strict immobilization of three months is needed. The resin maintains the base of the thumb and wrist. Some specialists also take the bend during the first 6 weeks to avoid rotation of the hand. In case of movement of fractured bone fragments, it must operate for remboîter and screw. With the resin, you can keep fit on your bike but it should not go bowling because access to the brake lever is not at all clear!

Clavicle fracture.

In falling, if you do not have time to get your hands forward to break your scaphoid ... you hit the floor with your shoulder ... and you may collarbone fracture. This time, the pain is intense and often deformation is visible under the skin! Clavicle connects the front of the thorax to the arm by means of the scapula. When it breaks, the bone fragments are often slightly displaced but exceptional that we should make to align and secure with a metal plate. To stop your collarbone broken during its consolidation, your doctor has two solutions. Either it puts you a band with which you keep the elbow to the body, or it keeps your shoulders well back with a thong in eight crossing in the back. In any case, we must keep the equipment for three to four weeks. A few days after your fall, when the pains have faded, try to pedal a bike very stable room, back straight, without holding the handlebars. This way you can keep a minimum of fitness.

The prices of fracture

On a good somersault bike, your bust can hit the tarmac. Odds to protect your heart and your lungs are used as bumper and can break. This type of trauma really suffer. Consult your doctor to achieve the necessary balance. But know that a simple contusion of the chest with some muscle spasms also cause severe pain. If the X-ray confirmed the fracture you sore for at least 1 month including coughing or turning in your bed Some doctors may suggest the establishment of circular bands to reduce the amplitude of respiratory movements painful. However, no rigorous asset chest is only possible ... under penalty of suffocation! While it is mostly painkillers and muscle relaxants drugs that contribute to your relief during this difficult time. Again, it is possible to gradually make the bike. Start straightened in the saddle and then 10 to 15 days after injury try to catch some time the handlebars. At first, to limit movement odds, avoid too intense workouts causing shortness of breath.

Muscle contusions

When you fall, your muscles can also be bruised. The fibers are crushed and small blood vessels through the muscles can tear. To promote healing, it is imperative to limit the volume of the hematoma. Although the shock has seemed trivial, shorten your exit and go directly to reduce muscle lacerations. Upon your return, glaze the traumatized area for at least 20 minutes while protecting your skin with a cloth. Cold closes the blood vessels and decreases bleeding. If your thigh or calf banged on the frame, surround them with a slightly compressive band and elevate your leg by putting your ankle on a chair. Your doctor may need to prescribe an ultrasound to assess the size of the hematoma and possible to do punctured. A few days after injury, when the lesion is bleeding more, it is good to remake muscle function smoothly. Pressure variations obtained through alternating contractions / relaxations promote the drainage of residual hematoma. Moderate stretching it possible to direct the healing of muscle fibers. quiet bike and physiotherapy help you recover!


A cramp is a powerful contraction, painful and involuntary muscle or an entire muscle group. It is caused by rapid diffusion through the muscle cell an electric current commanding the sliding of the fibers. Many contributing factors are to accrue to initiate this process. The nervous system contributes in two ways. First, it sometimes imposes a shortened position to muscle. A bike, the calf raised heel is now more often a victim of cramp. Second, in cold weather, it forces the muscles to stay toned to produce heat. The electric wave is creating more easily when there is an imbalance in muscle minerals. The acid accumulation and lack of available power disrupt the proper distribution of electrical charges. So to avoid cramps, you should cover your legs at the first frost. It is necessary to gradually warm up and the right amount your effort. Throughout the release, even in winter, it is imperative to make an effort to drink containing sugar and minerals. If your calf manifest some inclination to cramp, stretch the heel down when the crank is facing down. Keep pedaling avoiding over-stretching it. Just make sure you press your pedals, give up for a time to actively flex the knee.

The kneecap pain

Your head is located at the lower end of the large muscle of the thigh, the quadriceps. As you pedal, the latter powerfully shrinks, expands your knee, while rubbing your patella on the femur. Pain may occur if your bike is set incorrectly, if you abuse the large gears or if you run out of physical preparation. These sufferings are favored by a joint in which the patella is not properly seated. They can also activate at the time of a front impact of the knee. To avoid them and look after them, trying to raise a little stool to reduce the crushing of the patella when the knee is bent. Moulinez and turn the legs to at least 80 revolutions per minute. Opt for automatic pedals releasing rotations and do not overtighten resistance heaving. Stretch and strengthen your thigh to your muscle more smoothly guide your ball. It is strongly recommended to consult your after falling on the knee. It surely will offer to take anti-inflammatories. In addition, it will avoid pedaling too vigorously for a few weeks. The advice of a doctor of the sport and the realization of radiographs can be useful to take stock of the shape of your articulation between the patella and the femur. In case of anomaly, some rehabilitation and protective drugs of cartilage can complete a practice of good conduct cycling.

The patellar tendinitis

The patellar tendon is the fibrous cord connecting the bottom of the ball joint at the upper end of the tibia. Usually this tendon suffers when put in elastic tension repeated particularly in disciplines where races and jumps accumulate. A bike, this injury is much more exceptional. It is caused by the percussion tip ball against the banks of bone corridor in which it slides, when it tries to enter. To avoid this problem, it is imperative that the ball remains in the rail throughout the pedaling cycle. For this, we must not be too that the knee extension when the handle is down. The seat post should not be too high. If you feel that the bottom of the kneecap pain, just on its tip, try a little lower your saddle. The usual settings criteria normally used to keep a ball engage well in his lane. Take care to do leg stretches to loosen your tendon. Free spins on your clipless pedals to support the parallelism between the patella and its sliding rail. In the absence of relief, ask your doctor sport. An X-ray and ultrasound used to take stock of the tissue damage. Physiotherapy and anti-inflammatory may help to overcome the difficult hurdle.

Low back pain

Drive hours, leaning forward occasionally causes in low back pain. In this position, the front side of the intervertebral disc, these small shock absorbers between the vertebrae, eventually settle. To limit your suffering and decompress your disks, it is advisable to change positions. Feel free to completely straighten you and time to time and to dig back. To less pull your spine, raise a little your stem and make sure your saddle nose is not facing up. In order to reduce these tensions, make relaxation of muscles located in the back of your thighs and along your back. Reduce twisting of your spine by fixing your shoulders with a wide grip on the handlebar. Stabilize your pelvis slightly lowering your saddle. If any difference in length of your legs, adjust the height of the stem on the shorter leg. If, despite this good advice your pain persists, make an appointment with your doctor sport, it probably will look for a herniated disc and will prescribe physiotherapy.

Tendinitis of the crow's feet.

The tendons of the crow's feet are comprised of 3 fibrous cords that differ in the manner of a paw gallinacean. They connect the muscles in the inner thigh at their point of attachment on the top of the tibia. He suffers when subjected to excessive traction. As you know now, it is the elastic tension starts that attack especially tendons. Also, this injury it is rare. It is most common among convicts of the road. Most often, it takes cares of material to trigger the pain. Two problems can usually be the cause of increased traction on the inside of the knee, first, a wedge blocking foot too much external rotation; secondly, an axis of twisted pedal up on the occasion of a fall and tilting the knee to the frame. To be relieved, it is essential to repair your bike and change the setting of your dock so that the toe is directed more inward. Sometimes you have to add, for some time, an anti-inflammatory and physiotherapy treatments to soothe the irritation.

The external-iliac endofibrose.

The external iliac artery causes blood carrying oxygen to the muscles of your thighs. It passes in front of your hip. Every pedal stroke, she bend ... especially amply as you ride lying on the handlebars! A force to twist, she abyss and walls trying to repair by forming a thick scar. This last part can clog the artery. Again, rest assured, you will not be victim of this disease by walking twice a week. This injury does not appear within 10 000 km per year! Often, the cyclist suffers only one leg, the one he pushes harder. His pain is slowly moved when his muscle oxygen deficiency during a more intense work. It is typically triggered by a start or during a breakaway. He often described too tight shorts sensation. To make the diagnosis, one must go to a specialized hospital service to pedal a stationary bike. The doctor then found that the pressure in the leg arteries decreases the effort intensifies instead of increasing! Before operating, the surgeon desires to view the artery partially obstructed on a radiograph in which is injected a contrast medium into the blood vessels. To prevent this damage, passionate riders take care to avoid "unnecessary kilometers" by seeking the most effective training program. It will also not abusing attitudes too flexed guy "against the clock".


Hemorrhoids are varicose veins located around the anus. During your riding, these enlarged veins undergo numerous friction against the saddle. Sometimes they get irritated, bleed or become infected. If you are subject, a saddle with a hole next to the perineum is recommended. Avoid driving too often saddle nose. Alternate sitting work and dancer to decompress your gluteal area. Be draconian perineal hygiene and clean your cycling shorts after each output. Opt for a synthetic chamois retaining its flexibility despite repeated washing. Beyond this these tips, bleeding or pain around the anus require medical attention. Your doctor will probably suggest you to add to these recommendations a traditional treatment cream base and activator of venous return. It will seek a clot type complication or infection. Above all, it will take care to eliminate a digestive cancer symptoms responsible neighbors.

The "fire walk"

When the sunny days come back, when you prolong your workouts of Sunday, you may suffer the "fire walk"! This is a burning sensation in the foot favored by blood stagnation. In fact, venous return is not always easy when pedaling. The knees and hips are flexed and crank will amply vessels that cross. The arch is suspended in the air and the blood that accumulates is not easily removed. Finally intense efforts may be responsible for respiratory blockages that disrupt the aspiration of blood to the bust. To limit the "fire walk", choose shoes the coating allows air to flow above and do not over tighten the Velcro. Breathe fully and do not tilt too torso. If necessary, get off your bike and walk without shoes and wet your feet. Consider practicing complementary physical activities. Jogging or hiking are working your arch and boost your venous return.

The Iroman lack of iron, the other sports too!

Doctor St├ęphane CASCUA.

Iron is essential to your health and performance. It is a central component of hemoglobin. The latter is contained in red blood cells and gives it color. It is the iron that captures oxygen when blood passes through the lungs. It carries the precious gas to muscles. When they arrived, it drops its cargo which then allows the burning of energy substances and muscle contraction.

When you run or when you jump, your heels hit the ground and the fat pad of the foot of the plant is crushed. It is through many blood vessels. These red blood cells burst and release their hemoglobin. Iron is released into the blood and pass into urine.

Muscle contains a twin sister of hemoglobin, myoglobin. The latter also contains a lot of iron which sets some oxygen. This small local reserve allows starting the contraction before the blood vessels do not provide the necessary complement. When you experience aches, your muscle membranes are victims of micro-fissures. Myoglobin and iron leaves the muscle and gaining the blood. The precious metal is eliminated in the urine.

When you make an effort, the majority of blood flow is directed towards your muscles. There remains very little to the digestive tract and the bladder wall. These organs suffer from lack of oxygen and are shaken with every stride. Small areas are damaged and start to bleed. Red blood cells and iron are lost in the feces and in urine.

You enter the assiduous why athletes often lack iron, especially if they do not take care to concoct "menus and recipes" adapted. Sports are even more concerned since all these iron losses are added the massive elimination of blood during menstruation!

That is why it is good to occasionally perform a blood test to assess the stock in body iron. This levy is necessary when it comes to review a state of fatigue. It unnecessary to dose iron in the blood because the body is able to keep within the limits of normal while the reserves are at their lowest! It is necessary to measure levels of "serum ferritin" because this structure is the storage form of iron.

The bone is strengthened or crack in contact sports

Doctor St├ęphane CASCUA.

Each sports movement constitutes a solicitation for the bone structure. At each reception process, the tibia runner undergoes vibratory impacts. Unrolling not, the hiker twists slightly small bone in his foot. Even the body-builders, powerfully contracting its muscles, pulls on his bone.

Each strain injures a little bone of sports. Fortunately, during the rest period, the bone trying to rebuild. If time allows, if they bring him the necessary food, it is repaired! It reconstructs even louder than before as if to prepare for new mechanical attacks. This phenomenon is called by coaches cycle decompensation / overcompensation. This process has been described in many body organs and functions: muscle, stock energy, hormones, etc. It is a key driver of growth.

Thus, it was shown that the well-trained marathoner had stronger bones than sedentary. Indeed, its more dense bone structure, higher in fiber and calcium. In addition, the microscopic architecture of the bone is perfectly oriented along the axis of mechanical stresses.

Indeed, the chemical structure of the bone is comparable to reinforced concrete. The protein network is the steel rods. Calcium is comparable to concrete mired these metal axes. At the hip and pelvis direction of the bone structure is very characteristic. On a radiograph, it is found that the fibers leave the femur, the thigh bone, tilt in, come from hip to withstand the weight of the body resting on the hips. The lines of force from the right leg and left leg meet in the middle of the basin and support each other in the manner of the nave of a church.

Physical activity associated with a sufficiently high protein diet, vitamin D and calcium is a great engine of bone construction. This cocktail is particularly useful to hinge periods of life. During growth, it is necessary to eat 4-5 dairy products every day to build strong bones. It should also move: it is essential to practice a sport requiring the running and jumping at least 3 times a week for 30 minutes. In the absence of impact, bones harden less. It has been shown that a young competitive swimmer had lower bone density than sedentary because he was deprived of gravity during those long hours of pool training. In addition, bone densification stops 25 years. At this age you have made up your bone capital for life!

In adulthood, sport reinforces very hard bone and the amount of calcium necessary for the maintenance of bone is still debated. In case of fracture, the rest of the broken area needed a few weeks to allow to "ensnare" the broken area. In addition, gradually increasing mechanical stress are indispensable to "mechanize" the callus. Again, they help to guide the fabric of the bone in the center of the constraints to prepare him for his mission. An increase in calcium intake in consolidation period is proposed by some doctors without that interest has been really shown.

After menopause, the bone structure is gradually degraded to make the brittle bones is osteoporosis. Ladies, remember, your resistance to hip fracture depends on your diet and your sport for 25 years! If physical activity after menopause can no longer denser bones, reduces the loss of bone tissue. So it is advisable to go see jumping around or jog. It is also good to make the soft gym to maintain bone strength to strength. To make the most of this stimulation, it is again necessary to take 4-5 dairy products daily. It should also go out every day to enjoy the sun and make the vitamin D essential for the absorption and calcium binding. Fresh coordinating sports such as Thai Chi or "balance workshops" have proven effective in reducing the risk of falls and fractures.

If the sporting activity is excessive, the micro-cracks caused by impacts on the bones fail to consolidate over the rest. Rather, these lesions worsen in the next workout. Finally the splits right through bone, it breaks without any violent trauma. It is the stress fracture. In a postmenopausal woman, it was demonstrated that 6 hours of sport load per week may be sufficient to break insidiously bones. Among younger adults, this type of injury is favored by dietary deficiencies and hormonal disorders. Lack of calcium, vitamin D and protein alters the rebuild bone victim of microcracks in the exercise. Insufficiency sex hormones reduces the stimulation microscopic chemical plants be responsible for the synthesis of bone tissue. Functional changes occur when the deep depletion of the body. That kind of burnout is most often diagnosed in women because it causes menstrual irregularities and a cessation of menses. The victim is found in a state of "early menopause". In humans this hormone suffering is more insidious but it exists and its effects on bone density are comparable. The sports overwork cocktail, dietary deficiencies and disappearance of rules typically found in young women anorexic. Faced with a stress fracture, the sports physician must remain vigilant. It should not simply treat a "bone". It has an obligation to support a whole person, he is responsible for seeking overtraining or behavioral disorders.
