Throwing Injuries In Children

children baseball throwing injury Little Leaguer Youth Pitcher Elbow

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

In baseball, especially at the beginning of the season, there is an increase in elbow problems amoung young players. The most common elbow problem is the medial apophysitis named « Little Leaguer or Youth Pitcher Elbow ».

The elbow joint is composed of 3 bones : upper arm bone (humerus) and 2 bones in the forearms (radius and ulna). Muscles, ligaments and tendons keep the elbow joints together.

Little Leaguer Elbow

This injury occurs when repetitive throwing creates an extremely strong pull on the tendons and ligaments of the elbow. The pain felt to prominence inside the elbow.

« Pitcher’s elbow » can become serious if the case gets worse. Repeated pull can tear ligaments and tendons of the bones. The tear can take tiny pieces of bone like when a plant takes piece of the soil when it uprooted. This can destabilize bone growth, which can create a deformity.

Symptoms

« Pitcher’s elbow » can cause pain in the elbow. If any of these symptoms occur, it’s recommended to stop the throws :

  • Elbow pain
  • Decreased movement amplitude
  • Locking or snagging in the elbow joint

Treatment

Elbow injuries by lanching movements can become complicated cases, if they’aren’t treated.

Non-surgical treatment

Younger children respond better to non-surgical treatment :

  • Stop throwing because continuing to do this can create major complications and may reduce a child’s ability to remain active in a throwing sport.
  • Use an ice bag to decrease swelling
  • If the pain continues after a few days of complete rest in the affected area or if the pain reoccurs when the throwing starts, stop the activity again until the child is treated.
  • Improve the technique of launched

Surgical treatment

Surgery is sometimes necessary for serious injuries, mainly for girls older than 12 years old and boys older than 14 years old.

Depending on the child’s injury, surgery may includes bone fragment removal, bone grafting or reattaching a ligament back to the bone.

Recovery time

The recovery time depends on the age of the athlete and the severity of the injury. If the injury detected early and the modification of the activity begins, there will be little time required for the athlete to start the sport again.

However, if the athlete continues to play despite the pain and other symptoms, it will take several months to heal the injury. Or it’s possible that the injury becomes permanent.

Prevent

The recommendation for a child to be safe is 15 for 8-10 years old, 100 for 11-12 years old and 125 for 13-14 years old. This involves training and competitions. To avoid pitching injury, young pitchers should play 3-4 inning each game.

Abs Stretching

abs stretching anatomy

What’s up ? This is THE stephane ANDRE ! I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Lying on your stomach on your hands with your arms extended :

  • Straighten up your chest slowly by tilting your head back slightly

  • Maintain this position for few seconds while breathing slowly to feel the stretching of your abs.

Variant

It’s possible to make this movement with your hands on a bench and your feet on the floor, or you’re lying on your back on a big ball (Swissball).

Note

Stretching of abs can be an important element in some sports like throwing sports, especially the javelin. In this type of sports, it’s essential to have good flexibility and a good abdominal amplitude to make the movement perfectly.

Attention

Abs stretching are to be avoided in case of lumbar pathology.

Note

The position tilted forward (anteversion) of women’s pelvis allows a portion of the child’s weight to be transferred to the abs. By analogy, abs muscles can be compared to a « hammock ».

Floor Hip Abductions

foor hip abductions

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Lie on your side with your head and shoulders on line :

  • Raise your leg to an angle of 70 degrees (at the most off the floor, always keeping you knee extended).

 

  • Back to the starting position

 

gluteal muscles iseertions

This exercise works gluteus medius and gluteus maximus, It’s possible to make this movement with a large amplitude or a small amplitude. You can do an isometric contraction holding the position for a few seconds at the end of abduction.

Individual Variations In Hip Mobility

hip mobility

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Without taking into account the individual differences in muscle elasticity and ligament laxity, it’s bone shape of the hip joint that determines the main variation in hip mobility.

It’s mainly in the amplitude of hip abduction that bone configuration plays an important role.

Examples

  • An almost horizontal femoral neck (coxo vara) with an upper edge of the important cotyloid cavity and covering, will limit abduction movements.

  • An almost vertical femoral neck (coxa valga) with an upper edge of the less important cotyloid cavity will facilitate abduction movements.

This means that it is useless to raise the leg very high laterally if the morphology doesn’t allow it.

Attention

If someone forces the hip’s abductions, femur’s neck will bump on the cotyloid cavity edge. And this person will compensate the lateral raise of the leg with a pelvic tilt on the femur head of the other leg. It should be added that forcing oneself to make abduction sets may, over time, create microtraumas in some people that will cause excessive development of the cotyloid cavity upper edge. This has the consequence of limiting the hip’s mobility and creating painful inflammations.

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

bridge anatomy

Lie on your back with your hands flat on the floor. Your arms along your body with your knees bent :

  • Inhale and lift your buttocks from the floor by pushing hard on your feet

  • Maintain the position 2 seconds and go down your pelvis without touching the floor.

  • Exhale and start again.

This exercise mainly works hamstrings and gluteus maximus.

This movement is to be done with sets of high reps because the goal is to feel the contraction at the end of every repetition.

Note

Easy and effective, this exercise is very popular in aerobics classes.

Variant

Bench bridge :

bench bridge anatomy

Lie on your back with your hands flat on the floor. Your arms along your body with your thighs vertical and your feet on the bench :

  • Inhale and lift your buttocks from the floor by pushing hard on your feet

  • Maintain the position 2 seconds and go down your pelvis without touching the floor.

  • Exhale and start again.

This exercise works gluteus maximus and especially hamstrings because hamstrings works more here than bridge on the floor.

This movement is to be done slowly, the main thing is to feel the muscles contraction. Sets of 10 to 15 reps give better results.

With calves on the bench, you’ll work even more intensely your harmstings with gastrocnemius muscles.

You can also do this movement with a small amplitude without touch your buttocks on the floor and looking for the burning sensation.

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Kneeling on one leg and the other under the torso. You’re resting on your elbows or on your hands and your arms outstretched :

  • Tuck your opposite leg under your chest

  • Move your tucked leg to the rear until your hip is fully extended.

floor hip extension

This exercise performed :

  • Outstretched leg works hamstring and gluteus maximus

  • Flexed leg works gluteus maximus in a less intense way

Adapt Your Training To Your Morphology (Part 2)

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Legs

Improve your squat position

anatomy body squat morphology knee big belly

To reduce the lower back’s effort and limit the hamstrings tension, it’s possible to do like powerlifters by putting the barbell on posterior deltoids.

This technique decreases the cantilever and increases the power of lifting from the back. This allows you to lift heavier weights.

By using powerlifter of weightlifting shoes (solid raised heel) or a wedge under the heels, this reduces the cantilever by having the buttocks not too back by the advancing knees. This allows for greater amplitudes with the thighs flexion.

With that, we feel better the quadriceps work by limiting the torso’s inclinaison and the work of the gluteus maximus and spinal erectors.

The low barbell and raised heel combination allows you to lift heavier weights. This technique is recommended for rangy people and people with stiff ankles to correct their positioning at squat.

Front squat to target quadriceps

anatomy body squat morphology knee big belly

Front squat limits the torso’s inclinaison. This has the effect of reducing the work of the lower back, decrease the tension of hamstrings muscles and adductor magnus muscle.

On the other hand, front squat increases the cantilever, which forces quadriceps to make more effort to extend the thigh on the leg.

Which means it’s the perfect squat for thighs. But it’s not possible to lift heavyweights like the classic squat and it’s recommended to do it with heels elevated for better stability.

For rangy people, front squat is very hard to do. The torso of rangy people is more inclined, which make it more difficult to hold the barbell which may fall forward during the execution of the movement.

Spread the legs to less incline the torso

anatomy body squat morphology knee big belly

There is a squat’s technique to limit the torso’s inclination. This involves spreading the legs with the feet outward. Some powerlifters do this technique with the legs almost wide apart. With the legs apart, this limits the legs flexion.

To be able to squat with the legs apart, it’s necessary to have an adequate bone conformation of the hip joint and to be flexible of the thighs adductor muscle. Which means, it’s a technique that can’t be used by everyone.

The advantage of the big belly

anatomy body squat morphology knee big belly

Having a big belly for squat and deadlift allow to compress it against the thighs. This helps to limit the inclination of the torso and the back’s rounding. This has the effect of protecting the lower back and limiting the risk of herniated disc.

It’s for this reason that we can see a lot of heavyweight champion of powerlifting or weightlifting with a big belly. They take care to keep their belly fat with an excessively rich diet.

Different forms of knees

anatomy body squat morphology knee big belly

In bodybuilding, it’s important to take into account the different morphologies of the individual and especially for the knees.

Arched legs (genu varum) are not more risky than normal legs. For people with X legs (genu varum) or people who can overly extend the thighs (genu recurvatum), it’s often recommanded to not do leg exercises with very heavy weights.

Cases of genu valgum are often :

  • In people who were overweight during their youth when leg bones weren’t fully developed and still « malleable ». Legs are deformed because of the overload. Now, they have this X shape.

  • In women. The fact that women have wider hips to have children, this influences the femurs direction which are generally more inclined.

For people with genu valgum. If the genu valgum is to excessive, the joint would be overused. The medial collateral ligament would be extremely tense. The lateral meniscus, the articular surfaces coated with cartilage of the external condyle of the femur, and the external lateral tuberosity of the tibia would be subjected to excessive friction, which would cause pathologies of wear.

For people with genu recurvatum. These are people who are essentially very flexible named hyperlaxes or women whose muscular and ligamentous hyperlaxity is related to reproductive function.

Rarely pathological, knees with genu recurvatum can sometimes have some problems like the meniscus pinching. This can happen when the knees are rapidly expanding and the meniscus haven’t had enough time to slip, or during an exercise with a heavy weight that has forced the hyperextension of the thigh.

It’s for this reason that it’s recommended to people suffering from a genu recuvatum pathological never to totally block the knees at the end of extension to the squat or to the leg press.

Note

For 2 people who are the same size, it’s important to consider the torso-leg ratio.

anatomy body squat morphology knee big belly

Type A :

People with proportionally long legs and a short torso will have trouble doing a proper squat without tilting their torso excessively forward.

On the other hand, the short torso (which limits the cantilever) facilitates the execution of the good-morning, classic deadlift and Romanian deadlift.

Type B :

People with proportionally short legs and a long torso will have the facility to squat safety without tilting their torso excessively forward. It’s for this reason that the great champions of powerlifting squat specialist have this type of morphology.
