Don’t Forget Your Back

Most of us spend a large portion of the day hunched forward.  Think about when you are working on the computer, cooking, driving or even relaxing.  Your typical posture during these activities is head and neck forward, shoulders rounded forward, back curved and hips flexed.    When you remain in this position for an extended period of time, the muscles in the front of the body tend to shorten or contract, while the muscles in the back of the body tend to weaken.    This can be a set up for back, neck and shoulder problems and in addition, tends to make you look shorter, heavier and less confident.

Stretching before and after exercise as well as during the day is often overlooked in the rush to “get your workout in”.   Stretching however, has numerous benefits.   According to a study published in the Annals of Physical Medicine and Rehabilitation Medicine in September 2016, by I Fekhfekh, et al, dynamic muscle stretching of the knee musculature actually resulted in an increase strength gain in those muscles.  Interestingly, this study also found a decrease in the postural stability of the knee after stretching.    In English, it appears that stretching helps your to build strength, but may decrease the stability of the muscles you stretch at least temporarily.

In general, stretching helps to improve flexibility, joint range of motion, and usually is helpful for injury prevention.    Stretching helps by increasing blood flow to the muscles stretched.  This increased blood flow carries important nutrients to your muscles to allow for muscle growth and repair.  In addition, the increased blood flow helps to wash away muscle “waste” which leads to decreased soreness and inflammation of the muscle.

If allowed to remain in a contracted position for a prolonged period of time, our muscles will shorten.  For example if you spend a large portion of your day sitting in a chair or driving, the muscles in the front of the hips, your hip flexors will shorten.  These muscles have a direct effect on both your posture and your back health.

 

So what should you do?

It is important to stretch the muscles in the front of the body at least daily.

Exercises that focus on the hip flexors:

-Kneeling hip flexor stretch  – in the position of a lunge, allow your back knee to touch the floor and drive the hip of your front leg forward.  This will stretch the hip flexor of the knee on the floor

–Pigeon stretch – extend your right leg straight back and bring the heel of your left leg underneath your right hip.  Then drive your hips forward towards the ground.  Stretch and repeat on the other side.

– Yoga poses such as: low lunge, crescent lunge, upward facing dog, and revolving side angle pose

 

Stretches that focus on the chest muscles and prevent rounded shoulders:

– Door Frame stretch- stand in a doorway or at the corner of a room with your arms up like you were going to stop traffic.  Line your arms up from the elbow to the hand with the doorframe or in the corners of the wall.   Step towards the door and you should feel a stretch in your chest (pectoralis “pec” muscles) and hold for 20-30 seconds.

– Wall slides – stand with your back to the wall and keep your shoulders against the wall.  Walk forward 1-2 steps and slide your arms up and down the wall and squeeze your shoulder blades together.  You should feel a stretch in your upper chest muscles.

–Shoulder squeeze stretch –  clasp your hands together behind your back and slowly try to lift your hands.  Squeeze your shoulder blades together to stretch out the chest wall.

– Yoga poses include : bridge pose, camel pose, cobra pose and cow face pose

 

Stretches for your neck:

– Chin Tucks (Neck Retraction) – keep your shoulders back and your head in a neutral position (eyes facing forwards, chin level) slowly move your head backwards until you feel a slight stretch in the back of your neck.  Hold for 10-20 seconds and repeat.  If needed you can apply a gentle pressure on your chin with your fingertips to press your chin backwards and deepen the stretch.

Incorporating these exercises into your daily routine will help to prevent shortening of the muscles in the front of the body which leads to poor posture and often pain of the neck and back.  As always, if you are having pain which persists you should be evaluated by a certified health care professional to ensure that these exercises are safe for you.

This week we primarily discussed stretching exercises to prevent muscle contraction, and next week we will discuss the importance of strengthening the back muscles to further combat the issues of a hunched posture.

Common Causes of Knee Pain

The primary function of the knee is to bend and straighten the leg, to allow for a smooth gait during walking and running and to allow for jumping.    It is very common to develop knee pain in both new and seasoned exercisers.  Often the type of pain which develops is related to the type of exercise being done.

To understand knee pain, it is helpful to have a basic understanding of knee anatomy.

The knee joint can be divided into intra-articular and extra-articular compartments.

Intra-articular – structure inside the knee  joint

Extra-articular – everything else

The knee joint is where the surfaces of the leg bones meet and interact.  In order for the bones to move smoothly against each other and to provide additional stability, there is articular cartilage or cushioning shock absorber called the meniscus on both sides of the knee joint.  There are also many important ligaments which connect one bone to another and provide stability.  In addition, there are fluid filled sacs called bursae which allow for separation between solid tissues so that smooth movement can occur.

To help visualize the components of the knee, let’s break it down into 3 parts.

  • The anterior (front) of the knee
    •  Knee cap or patella
    •  Quadriceps tendon
  •  The medial aspect (side) of the knee  closest to the other knee
    • Medial meniscus (cushion)
    • Medial part of the joint capsule (the whole joint capsule encloses the entire knee)
    • Medial Ligaments  (provide stability for the knee and connect bone to bone)
  •  The Lateral aspect (outer) part of the knee
    • Lateral part of joint capsule
    • Lateral meniscus
    • Lateral ligaments

The knee is actually more complex then described above and does have the ability for rotation in addition to bending and straightening and other components not described above.  For the purpose of this article, we will focus on basic knee motions and components.

Now that we have a basic understand of the knee, let’s focus on what can go wrong with the knee.

In general, knee pain can be caused by:

  • Injuries due to trauma
  • Overuse injuries due to
    • Body misalignment
    • Muscle imbalances
  • Degenerative conditions
  • Injuries in the hips or feet

Patellofemoral syndrome (Anterior knee pain – front of the knee)

Common in new exerciser, especially runners and jumpers.  This is usually due to irritation between the patella (knee cap) and femur (thigh bone).  This pain can occur with increased jumping, squatting, running and climbing stairs.  Usually pain occurs if there is repeated stress on the knee or if there is a sudden significant increase in physical activity.   It is often treated with rest, ice, elevation and compression (RICE) and specific exercises to strengthen muscles surrounding the knee, and core.

Structural Injuries 

Knee injury can also result from structural changes or damage such as a dislocation, slippage or tears of the menisci or ligaments surrounding the knee.

Meniscal Injuries – The meniscus serves as a shock absorber for the joint.  Injuries of the meniscus can be the result of a twisting injury and can cause considerable pain, joint swelling, difficulty with stairs and the sensation of locking of the knee.  Occasionally the pain in the joint due to meniscal injuries will cause the brain to “shut off” the quadriceps at the knee causing the knee to “give way”.

Ligament Injuries – Ligament tears, such as a tear of the ACL (anterior cruciate ligament) can occur with a twisting injury and results in knee instability and may require surgical intervention depending on the degree of the tear.  It is common to sense a “pop” and immediate leg instability with this injury.    If surgery is used to repair the ACL, recovery is long and only low impact exercises are recommended initially to strengthen the muscles around the joint.  In contrast, PCL (posterior cruciate ligament) tears often can be treated non surgically with physical therapy and if indicated bracing.   When ligaments are torn or lax (loosened) it is common to have the sensation of poor balance or joint instability.

Tendon Injuries – Tendons are tissues that connect muscle to bone.  Typically, complete tendon ruptures are abrupt and result in the inability to move the joint.  The quadriceps tendon is quite large and a significant amount of degeneration must be present for it to rupture.  More often this injury is the result of a high force injury.   A completely torn tendon requires surgical intervention, but a partially torn one, will likely heal with immobilization followed by physical therapy.

Overuse injuries

Overuse injuries such as bursitis (inflammation of bursae), tendonitis (inflammation of the tendons), muscle strains, and Iliotibial band syndrome are usually the result of repetitive stress on a muscle, tendon or bursa.  Usually there is a component of body malalignment, muscle strength imbalance, improper shoe wear, or poor form which leads to the development of these conditions.  Treatment may include RICE (rest, ice, elevation, and compression) along with a detailed musculoskeletal exam to determine the etiology of the injury.  This will allow for a proper treatment plan to prevent recurrence.

Arthritis

Arthritis can be divided into Osteoarthritis (wear and tear), Rheumatoid (immune mediated), Gout (due to gout crystal build up) and Septic (due to infections).   Arthritis may be the result of poor diet or gluten sensitivity in some individuals.   While some forms of arthritis are genetic, diet modifications, weight loss, proper shoe wear and exercise may help to offset the severity of these conditions.

Fish Oils

Fatty acids have many important uses in our bodies.  Fatty acids come in different shapes and sizes, and are named based on their size and chemical structure. Omega-3 fatty acids are a specific class of fatty acids that are utilized by our bodies and are used as the precursors for anti-inflammatory compounds.

Essential Fatty Acids are those that cannot be made by our bodies and must be consumed as part of our diet.  The name Omega -3 Fatty acid describes a class of different length fatty acids which all contain a similar chemical structure.

The most well-known Omega 3 fatty acids are ALA (alpha linolenic acid), EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).

ALA is found in:

  • Flaxseed
  • English walnuts
  • Brussel sprouts
  • Salmon
  • Sardines
  • Chia
  • Hemp
  • Tofu
  • Spinach
  • Other plant foods

The body in theory has the ability to convert ALA into DHA and EPA.  However, this pathway is influenced by dietary intake and does not work optimally in all people.  Therefore, it is often helpful to consume foods with DHA and EPA in case the body is unable to make these compounds in the needed amounts.   There are multiple studies that have shown the health benefits of DHA and EPA and I will describe these in more detail later in this article.

EPA and DHA are more difficult to obtain with a strict vegetarian diet.  Sea plants and certain fermented foods do contain small amounts of DHA, but DHA is not found in land based plants.  DHA makes up about 20% of the brain by weight, and is found in most fish, eggs, and milk and cheeses obtained from grass fed animals.   EPA is found in most fish, especially salmon and sardines.  The amount of EPA and DHA in fish is dependent on their diet.  Farmed fish are sometimes supplemented with processed Omega-3 fatty acids to increase the concentration found in these fish.

Multiple studies have demonstrated the beneficial effects of Omega-3 fatty acids, specifically EPA and DHA, for our general health and well-being.  Below is a summary of my review of the literature, and the findings in various studies:

  • Fish oils lower blood sugar and decrease liver fat stores
  • Increasing DHA and EPA decreases the incidence of metabolic syndrome by 20%
  • EPA and DHA supplementation helps to lower blood pressure (at approx. 1gm/day)
  • In obese patients, insulin sensitivity is improved with supplementation of EPA and DHA (at approx. 1 gm/day)
  • Higher levels of EPA consumption lower risk of CHF (congestive heart failure) and increase survival in patients with heart failure by 35% – thought to be because of the effect on the heart muscle pumping ability
  • Omega-3 fatty acids improve exercise-induced asthma and increase pulmonary function 5-fold based on pulmonary function tests
  • Fish oils help to slow neuro-inflammation and may slow progression of neuro-degenerative disorders (eg. Alzheimers, Parkinson’s)
  • Mild cognitive dementia improves with supplementation of 900mg of DHA
  • Omega-3 Fatty acids may slow or reverse nerve damage from diabetes

So what should you do?   All fish oils are not created equally.  Fish oil in its natural state obtained directly from the diet is probably best, but it is difficult to eat the amount needed by our bodies.   The next best option is supplementing our diet with at least 2.5 grams/day of EPA and DHA in the form of a pharmaceutical grade, highly refined Omega-3 fatty acid supplement (if ok with your doctor).  Unrefined fish oils can have many contaminants such as PCBs and Mercury.   Most fish oils sold over the counter have a very low concentration of EPA and DHA and contain “other Omega-3 fatty acids” which require our bodies to convert them into an active form.    As was stated earlier, ALA intake is important, but this needs to be converted into DHA and EPA in order to be effectively utilized in the anti-inflammatory pathway.

One final note is that while Omega-3 fatty acids such as ALA, EPA, and DHA are the precursors of anti-inflammatory mediators in our body, Omega-6 fatty acids such as AA (arachidonic acid) are the precursors of the pro-inflammatory mediators in our body.  Omega-6 fatty acids are found in many cooking oils such as corn, palm, sunflower, safflower and soybean oil.   The western diet is very high in omega-6 fatty acids and relatively low in omega-3 fatty acids.  By increasing the amount of omega-3 fatty acid consumption and decreasing omega-6 fatty acid consumption, the inflammatory state of the body is improved.  This is thought to have a beneficial effect of chronic inflammatory disease states such as arthritis.

Exercising With Arthritis

 

We have all different levels of fitness. Some individuals have been exercising for years, while other individuals have never exercised a day in their lives.  We are all at different levels in terms of our cardiovascular fitness, our muscle strength and flexibility and our overall health.   It is quite important to remain active in spite of arthritis.  In fact, movement in people with arthritis is crucial to health and well-being.

Despite what we once thought, it is my experience that it is possible to modify the severity of certain types of arthritis.   In my mind, arthritis, chronic pain and other autoimmune diseases are the result of multiple factors.  All these factors such as genetics, environmental exposures, nutritional deficiencies, dietary influences, and gut health to name a few factors, all line up as if you were to “win” in the slots.  When this potent combination occurs in your body, havoc ensues.   The result is inflammation and chronic disease.   While you can’t change your genes per se, it is now thought that you can change or modify your gene expression.  In addition, you can certainly modify some of the other risk factors just mentioned to offset the severity of your debility.

In most cases, moderate exercise is essential to health and well being.  Proper, varied forms of exercise raises heart rate, raises endorphins, improves muscle strength, improves balance, improves flexibility and increases blood flow throughout the body including the muscles and joints.  In the case of arthritis, there is inflammation in the joint capsule and the bones themselves which leads to severe pain and often deterioration.     The nerve endings in the joint become super sensitive and pain can be unbearable.

Believe it or not, your choice of diet can directly impact your ability to exercise. When you consume an Anti-Inflammatory Diet, often you will notice you will able able to exercise with less pain is because this diet eliminates many known triggers for arthritis.

 

Some examples of arthritis triggers include:

  • Fried and processed foods
  • Thought to be due to compounds called AGE – (advanced glycation end products) These products are the result of heating, grilling, and frying foods.  The body utilizes pro-inflammatory molecules called cytokines in an effort to break them down and the result is excess inflammation in general as well as in the vascular system (blood vessels).
  • Sugary foods
  • Dairy
  • Alcohol
  • Foods/Oils with Omega-6 fatty acids – such as vegetable oil (safflower), corn oil, fried foods, certain nuts and seeds, mayonnaise

 

Some examples of beneficial foods include:

  • Foods containing high levels of Omega-3 Fatty acids – (ex. salmon, herring)
  • Avocados
  • Flax seed
  • Cherries and other berries (contain anthocyanins that are thought to be anti-inflammatory)
  • Leafy vegetables, broccoli – contain vitamin D
  • Green tea – has EGCG (epigallocatechin-3-gallate) a powerful antioxidant
  • Vitamin C containing foods (ex. papaya, brussel spouts, broccoli, citrus fruits)
  • Garlic, onions and leeks

 

It is very important to listen to your body.  Pay attention to the foods you are eating and the way you feel.  Often times, foods that are considered healthy may cause issues for you.  If you suffer from arthritis, try rotating your foods (i.e. do not eat the same food everyday).   If there are certain foods you think might bother you, wait 3 days in between eating them.  Then pay attention to the way you feel when you re-introduce those foods.  If you notice you have more difficulty with pain or decreased ability to exercise try eliminating the offending foods for a week or two.

Typically, it will take several weeks of following the diet closely before you see results with regard to decreased pain from inflammation.

When exercising with arthritis, it is important to modify your exercises as per trainer recommendations.  If exercises hurt, if possible, discuss with your trainers to find another way to exercise that muscle group.  In the beginning, there may be some exercises you simply cannot do.  What is important is that you are attempting to exercise.  With each passing week you will find that you can do a little more than the previous week.  Progress may be slow, with ups and downs.  As always, if despite closely following the diet, you are still having issues, it might be time to seek the advice of a health care professional.
