Overuse Injuries

overuse injuries sport injury

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.

There are 2 types of injuries : Acute injuries and overuse injuries. Acute injuries are usually caused by a single traumatic event. Here are some examples :

  • Wrist fractures

  • Ankle sprains

  • Shoulder dislocations

Acute injuries are less common in sport than overuse injuries. Overuse injuries are usually subtle and appear over time, making them difficult to diagnose and treat. Here is some example :

  • Tennis elbows

  • Swimmer’s shoulder

  • Pitcher’s elbow

  • Runner’s knee

  • Achilles tendinitis

  • Shin splints

Why

Human body is extraordinary to adapt to physical stress. We’re used of thinking that « stress » is bad for our emotional well-being, but physical stress is simply doing an exercise or activity. This is beneficial for our muscles, tendons, ligaments and bones. This physical stress causes an internal process called remodeling. Remodeling process involves both the breakdown and the build up of tissue. It’s necessary to have a good balance between 2, if breakdown occurs more rapidly than buildup, an overuse injury occurs.

Causes

Usually, it’s training errors that cause overuse injuries. These errors are too fast acceleration of intensity or duration or activity frequency. These injuries can also happen to people who return to the sport/activity after an injury. They try to make up for lost time as quickly as possible to reach the level they had before the injury. Doing an exercise with a good technique is important to avoid overuse injuries. When the exercise’s technique is bad, it creates overuse injuries. It’s for this reason that coaches, athletic trainers and teachers can play a preventive role so that athletes avoid overuse injures.

There are people who more easily have overuse injuries. An unbalance between strength and flexibility around certain joints predisposes some people to have this type of injury. Body alignment, such as knock-knees, bowlegs, unequal leg lengths and flat or high arched feet, also impact overuse injuries. There are also people who have weak links because of old wounds, incomplete rehabilitation of wounds or others anatomy factors.

Other factors must also be taken into account as equipment such as the type of running shoe or ballet shoe and terrain (hard versus soft surface in aerobic dance or running).

Diagnosis

Generally the diagnosis is based on the athlete’s history and physical examination. It’s recommended to make a diagnosis with a sports medicine specialist with a specific interest and knowledge of your sport. In some situations X-rays, bone scan and MRI may be necessary.

Treatment

Here are some recommendations for treating an overuse injuries :

  • Cutting back the intensity, duration and frequency of an activity

  • Adopting a hard/easy workout schedule and crosstraining with other activities to maintain fitness levels

  • Learning about proper training and technique from a coach or athletic trainer

  • Performing proper warm-up activities before and cool down after

  • Using ice after an activity for minor aches and pain

  • Using anti-inflammatory medications as necessary

If symptoms persist, a sport medicine specialist may create a more detailed treatment plan for your specific condition. This may involve an exam of your training program and an evaluation of predisposing factors.

Prevention

Majority of overuse injuries can be avoided with a proper training program, common sense and learning to listen your own body. The quote : « No pain, no gain » doesn’t apply here. The 10% rule helps a lot to get things to the next level.

In general, you should increase the training’s intensity to a maximum of 10% per week. This allows your body to have enough time for recovery and response. This rule should be used to increase pace or milestone for walkers or runners. Or for the weights amount to increase for strength training programs. In strength training, add flexibility exercises and core stability exercises help tremendously to minimize overuse injuries.

It’s recommended to seek advice from sports medicine specialist or athletic trainer to prevent chronic or recurring problems. Your training program can also be modified to maintain fitness levels safety while you recover from your injuries. You must return to the sport only if an authorization is granted by a health professional.

Remember, it’s very important to warm-up before training and cool down after training.

Stats

3.5 millions of children are treated for overuse injures every year.

Adapt Your Training To Your Morphology (Part 2)

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

If you didn’t read Part 1, click here.

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.

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.

How To Do Trap Bar Deadlift

 trap bar deadlift

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

 

Audio file :

Standing in the center of the trap bar (be careful, if you’re badly centered in the trap bar, there will be a lateral instability). Your legs are slightly spread with your back rigid and a little bit arched :

Bend your legs to have your thighs a little closer to the horizontal. This position may be different from one person to another depending on the morphology and ankles flexibility. For example, a person who has long femurs and long arms will have thighs a little higher than the horizontal. A person with short femurs and short arms will have thighs horizontally

With your arms outstretched, take the handle, being careful to center the grip of your hands. Be careful with a heavy weight because a non-centered grip will rock the trap bar forward or backward.

Inhale and block your breathing. Squeeze your abs and your lumbar region. Lift the trap bar by straightening your legs being careful to not round your back during movement. Exhale at the end of the effort.

trap bar deadlift

Maintain the extension of your body (your body is straight) for 2 seconds and go down with the trap bar keeping your abs and your lumbar region squeezed

The trap bar deadlift works all your muscles body as the classic deadlift . The difference is that the central position of the bar makes it possible to limit the tilt of your torso which reduces the intensity of the work of the glutes and the lumbar region and transfer a part of the effort towards the quadriceps.

It’s for this reason that the trap bar deadlift can be included in a specific program to work the thighs and can replace squat in some cases.

The upper part of the trapezius work deeply with heavier weights.

Note

For people who suffer from lower back, this exercise is safer than the classic deadlift.

How To Do Stiff-Legged Deadlifts

stiff legged deadlifts

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

Podcast :

Standing with your feet slightly apart. The barbell is on the floor in front of you :

  • Inhale, bend your torso forward with your back arched. If you can keep your legs straight or slightly bent.

  • Take the barbell with a pronated grip and straighten your body with your back rigid (your back is not more arched than the starting position). It’s at the hips level that the tilt occurs. Exhale at the end of the movement.

  • Returns to the starting position without the barbell touch the floor and do it again.

To avoid to have injuries, keep your back straight, it’s important.

This exercise works all the spinal erectors, it’s the muscles that run along each side of your spine. These are the muscles that allow you to straighten your spine.

When you straighten your torso, during the tilt forward of your hips, this exercise works the gluteus maximus and hamstrings (except the thigh biceps short head).

This exercise stretches the back of your thighs when you return to the starting position.

It’s possible to raise your feet compared to to the barbell (with a plate weight or a step) so that the exercise is more effective.

Note

This exercise can be used as a stretching movement for hamstring with light weights.

The heavier the weight and the greater the gluteus will work compared to the hamstrings to straighten your hips.
