Preventing & Healing Repetitive Strain Injuries – Part 3

 Author: Julie Donnelly, LMT

 

These past two weeks we took a look at how muscles move the body, and why muscles cause pain. Then we looked at why strengthening isn’t always the best thing to do, in fact how it could even cause more pain. And finally today we’ll discuss why stretching can actually cause muscles to tear.  I call this the Stretching Misconception.

Stretching Shouldn’t Hurt!

Have you ever felt so tight when you tried to move a joint that you decided to stretch?  The odds are that you answered “yes” to that question.  However, many people complain that they feel worse after stretching than they did before stretching.

Before getting into the specifics of the stretching misconception there are two words that need to be clarified. Many people confuse the word “spasm” with “cramp”. A cramp (also called a “Charlie horse”) normally involves all of the fibers of a muscle, and is when a muscle suddenly contracts totally. A spasm is like tying a knot in the center of the muscle and while it may only involve a few fibers; there can be multiple spasms throughout the muscle.

Each spasm feels like a bump when you slide your fingers deeply down the length of the muscle. These spasms normally form over an extended period of time, often from repetitive strain on the muscle fibers. Spasms are at the heart of the stretching misconception, so it is important that you think of a spasm as a knot in the muscle fibers in order to understand why it can hurt to stretch.

As I mentioned in Part I of this series, a muscle begins on a stationary bone, crosses over a joint, and then inserts into a moveable bone. When the muscle pulls on the moveable bone, the joint moves, however, if the muscle has a “knot” in it you can actually cause micro-tears to the fibers as you stretch.

How Stretching Can Hurt Your Muscles

Stretching Analogy 1Think of this analogy: visualize a strong tree with a rope tied to it. The rope is the perfect length to attach to a flexible tree without bending the second tree. You can imagine if you pulled on the rope the flexible tree would bend over, and if you let go of the rope, the flexible tree would stand up straight again.  This is a simple explanation of how a muscle pulls on a bone and causes the joint to move.

However, if you tied a knot in the rope, the tree would bend. If you tied a second knot, the tree would bend even further. If Stretching Analogy 2you then tried to stretch the rope so the flexible tree was standing straight, you would cause the knot to get tighter and the remaining rope would have to overstretch on both sides of the knot in order for the flexible tree to stand up straight.

This is exactly what is happening when you have a spasm, or multiple spasms, in your muscle. As you stretch you are causing the knot within the muscle to get tighter, and you are also causing the fibers on either side of the spasm to overstretch. This overstretching may cause the fibers to actually tear either along the length of the muscle, or where the fibers attach to the bone at either end of the muscle. This can be avoided by simply massaging the muscle to release the spasm before you stretch.

It’s now easy to understand why the repetitive movements that you do on a regular basis will cause the muscle to ultimately shorten into knots that we call spasms or trigger points.  As I mentioned, when you try to stretch a spasm you can be causing yourself potential problems, and may even tear the muscle fibers.

Fortunately there is a solution. First you need to release the spasms that are causing the muscle to tie up into a knot, and then you can safely stretch. TriggerPointYoga was designed and developed to first eliminate the spasms in the muscle you will be stretching, and then continues to give four separate session of traditional yoga poses – two for the upper body and two for the lower body.  You will gain flexibility and range-of-motion without injuring your muscle fibers.

Preventing & Healing Repetitive Strain Injuries – Part 2

 Author: Julie Donnelly, LMT

bicepsIn part I of this series we explored “how” muscles cause joint pain and prevent us from moving easily and without pain. In Part II we’ll take a look at the “why.”

When a person can’t freely move a joint they are frequently told they need to strengthen the muscle that moves the joint, but this is often a serious misconception. Let’s look at this further so it will become clear.

Most people have heard the term Repetitive Strain Injury (RSI), but they don’t have a clear concept of how that affects them on a daily basis.

Repetitive Strain Injuries (RSIs)

Repetitive strain injuries happen when a muscle does the same movement over and over, causing the muscle to develop an excess of Hydrogen ions (H+), which is a part of lactic acid. Lactic acid was once thought to be the “bad guy” that created spasms/knots in your muscles.  Then research showed that lactic acid has two components, one is called lactate and it is an important piece of energy production, and the other is H+, which is the acid byproduct of energy production and is the cause of the spasms.

Your body has the ability to flush out H+, but if you are exercising, or repetitively doing the same movement, you are creating more H+ than your body can eliminate.  The scales tip and the excess lactic acid will cause the muscle fibers to contract into a spasm.  The spasm is usually formed slowly so you don’t notice it until it is so evolved that the fibers are twisted into a knot and are putting a strain on the insertion point at the joint.

Strengthening vs Lengthening

When you can’t bend a joint, such as your elbow, you are often told to strengthen the muscle that pulls on the joint, in this case, the biceps.  However, you actually need to lengthen your triceps.

In fact, I tell my clients to first look at the area where they are feeling pain, and then find out which muscle inserts at that point. If you can’t bend a joint, I tell people to look at what muscles should be stretching to enable the joint to move. The likelihood is great that the tight muscle is the cause your problem.

You’ll be amazed at how quickly you will regain full range-of-motion when you release the “straps that are holding you bound” by lengthening the contracted muscles.

Another piece of the strengthening misconception occurs when a person feels they are losing power in their muscle.  Many times the person isn’t feeling any pain in their body, just a general feeling of loss of strength. You know you are exercising, but still you aren’t as strong as you were, so you feel you need to increase your strengthening exercises.

How Strengthening Can Hurt Your Muscles

To demonstrate this topic we’ll use the biceps of the upper arm as our example.  I do a lot of my work with endurance athletes, athletes who are power lifters or simply individuals who exercise to the extreme.  I’ve seen how they are in severe pain, sometimes to the point where they can’t do even the simplest movements without having not only pain but also losing power.

Often they lose power because the pain is too sharp when they go to lift the weight, or do pull ups. Other times they just feel like they are having weakness in the muscle, which makes them more determined to exercise that muscle even more.  What has happened is the muscle is now too short to have any pulling power.

an upper body athletesLook at the graphic to the left.  Many endurance athletes look just like this drawing, and some people think this is the picture of strength.  However what is happening is the biceps muscles have been shortened to the point where he can’t completely straighten his arm, so he has actually lost power.

But you don’t need to be an endurance athlete to have this experience.  If any muscle in your body is shortened by spasms, whether they are from doing a repetitive movement or from exercise, you will also lose strength in those muscle fibers.

Consider this: if you couldn’t move your body, but you wanted to pull a heavy object toward you, you would stretch your arm out all the way and then pull on the object. If you stepped closer to the object so your arm is now bent, you can see that you wouldn’t have as much strength to move the heavy object.  In the same way, when a muscle is already shortened by either a spasm or a static contraction, it won’t have the full pulling power it needs to function properly. You need to lengthen the fibers to their optimal length so they can pull with full strength.

You stretch, but often people will complain that the muscles aren’t stretching, or they hurt worse after the stretch than they did before stretching. This brings us to the “stretching misconception,” which will be explained in Part III of this trilogy.

What Is The Planetary Diet?

Is Your Diet Destroying The Planet?

Author: Dr. Stephen Chaney

 

Earth Day has come and gone, but you are still committed to saving the planet. You save energy. You recycle. You drive an electric car. But is your diet destroying the planet?

This is not a new question, but a recent commission of international scientists has conducted a comprehensive study into our diet and its effect on our health and our environment. Their report (W. Willet et al, The Lancet, 393, issue 10170, 447-492, 2019 ) serves as a dire warning of what will happen if we don’t change our ways. I touched on this report briefly in a previous issue of “Health Tips From The Professor,” What Is The Flexitarian Diet , but this topic is important enough that it deserves an issue all its own.

The commission carefully evaluated diet and food production methods and asked three questions:

  • Are they good for us?
  • Are they good for the planet?
  • Are they sustainable? Will they be able to meet the needs of the projected population of 10 billion people in 2050 without degrading our environment.

The commission described the typical American diet as a “lose-lose diet.” It is bad for our health. It is bad for the planet. And it is not sustainable.

In its place they carefully designed their version of a primarily plant-based diet they called a “win-win diet.”  It is good for our health. It is good for the planet. And, it is sustainable.

In their publication they refer to their diet as the “universal healthy reference diet” (What else would you expect from a committee?). However, it has become popularly known as the “Planetary Diet.”

I have spoken before about the importance of a primarily plant-based diet for our health. In that context it is a personal choice. It is optional.

However, this report is a wake-up call. It puts a primarily plant-based diet in an entirely different context. It is essential for the survival of our planet. It is no longer optional.

If you care about global warming…If you care about saving our planet, there is no other choice.

How Was The Study Done?

The study (W. Willet et al, The Lancet, 393, issue 10170, 447-492, 2019 ) was the report of the EAT-Lancet Commission on Healthy Diets from Sustainable Food Systems. This Commission convened 30 of the top experts from across the globe to prepare a science-based evaluation of the effect of diet on both health and sustainable food production through the year 2050. The Commission included world class experts on healthy diets, agricultural methods, climate change, and earth sciences. The Commission reviewed 356 published studies in preparing their report.

 

Is Your Diet Destroying The Planet?

When they looked at the effect of food production on the environment, the Commission concluded:

  • “Strong evidence indicates that food production is among the largest drivers of global environmental change.” Specifically, the commission reported:
  • Agriculture occupies 40% of global land (58% of that is for pasture use).
  • Food production is responsible for 30% of global greenhouse gas emissions and 70% of freshwater use.
  • Conversion of natural ecosystems to croplands and pastures is the largest factor causing species to be threatened with extinction. Specifically, 80% of extinction threats to mammals and bird species are due to agricultural practices.
  • Overuse and misuse of nitrogen and phosphorous in fertilizers causes eutrophication. In case you are wondering, eutrophication is defined as the process by which a body of water becomes enriched in dissolved nutrients (such as phosphates from commercial fertilizer) that stimulate the growth of algae and other aquatic plant life, usually resulting in the depletion of dissolved oxygen. This creates dead zones in lakes and coastal regions where fish and other marine organisms cannot survive.
  • About 60% of world fish stocks are fully fished and more than 30% are overfished. Because of this, catch by global marine fisheries has been declining since 1996.
  • “Reaching the Paris Agreement of limiting global warming…is not possible by only decarbonizing the global energy systems. Transformation to healthy diets from sustainable food systems is essential to achieving the Paris Agreement.”
  • The world’s population is expected to increase to 10 billion by 2050. The current system of food production is unsustainable.

When they looked at the effect of the foods we eat on the environment, the Commission concluded:

  • Beef and lamb are the biggest contributors to greenhouse gas emissions and land use.
  • The concern about land use is obvious because of the large amount of pasture land required to raise cattle and sheep.
  • The concern about greenhouse gas emissions is because cattle and sheep are ruminants. They not only breathe out CO2, but they also release methane into the atmosphere from fermentation in their rumens of the food they eat. Methane is a potent greenhouse gas, and it persists in the atmosphere 25 times longer than CO2. The single most important thing we can do as individuals to reduce greenhouse gas emissions is to eat less beef and lamb. [Note: grass fed cattle produce more greenhouse gas emissions than cattle raised on corn because they require 3 years to bring to market rather than 2 years.]
  • In terms of energy use beef, lamb, pork, chicken, dairy and eggs all require much more energy to produce than any of the plant foods.
  • In terms of eutrophication, beef, lamb, and pork, all cause much more eutrophication than any plant food. Dairy and eggs cause more eutrophication than any plant food except fruits.
  • In contrast, plant crops reduce greenhouse gas emissions by removing CO2 from the atmosphere.

 

What Is The Planetary Diet?

In the words of the Commission: “[The Planetary Diet] largely consists of vegetables, fruits, whole grains, legumes, nuts, and unsaturated oils. It includes a low to moderate amount of seafood, poultry, and eggs. It includes no or a very low amount of red meat, processed meat, sugar, refined grains, and starchy vegetables.”

When described in that fashion it sounds very much like other healthy diets such as semi-vegetarian, Mediterranean, DASH, and Flexitarian. However, what truly distinguishes it from the other diets is the restrictions placed on the non-plant portion of the diet to make it both environmentally friendly and sustainable. Here is a more detailed description of the diet:

  • It starts with a vegetarian diet. Vegetables, fruits, beans, nuts, soy foods, and whole grains are the foundation of the diet.
  • It allows the option of adding one serving of dairy a day (It turns out that cows produce much less greenhouse emissions per serving of dairy than per serving of beef. That’s because cows take several years to mature before they can be converted to meat, and they are emitting greenhouse gases the entire time).
  • It allows the option of adding one 3 oz serving of fish or poultry or one egg per day.
  • It allows the option of swapping seafood, poultry, or egg for a 3 oz serving of red meat no more than once a week. If you want a 12 oz steak, that would be no more than once a month.

This is obviously very different from the way most Americans currently eat. According to the Commission:

  • “This would require greater than 50% reduction in consumption of unhealthy foods, such as red meat and sugar, and greater than 100% increase in the consumption of healthy foods, such as nuts, fruits, vegetables, and legumes.”
  • “In addition to the benefits for the environment, “dietary changes from current diets to healthy diets are likely to substantially benefit human health, averting about 10.8-11.6 million deaths per year globally.”

What Else Did The Commission Recommend?

In addition to changes in our diets, the Commission also recommended several changes in the way food is produced. Here are a few of them.

  • Reduce greenhouse gas emissions from the fuel used to transport food to market.
  • Reduce food losses and waste by at least 50%.
  • Make radical improvements in the efficiency of fertilizer and water use. In terms of fertilizer, the change would be two-fold:
    • In developed countries, reduce fertilizer use and put in place systems to capture runoff and recycle the phosphorous.
    • In third world countries, make fertilizer more available so that crop yields can be increased, something the Commission refer to as eliminating the “yield gap” between third world and developed countries.
  • Stop the expansion of new agricultural land use into natural ecosystems and put in place policies aimed at restoring and re-foresting degraded land.
  • Manage the world’s oceans effectively to ensure that fish stocks are used responsibly and global aquaculture (fish farm) production is expanded sustainability.

What we can do: While most of these are government level policies, we can contribute to the first three by reducing personal food waste and purchasing organic produce locally whenever possible.

What Does This Mean For You?

If you are a vegan, you are probably asking why the Commission did not recommend a completely plant-based diet. The answer is that a vegan diet is perfect for the health of our planet. However, the Commission wanted to make a diet that was as consumer-friendly as possible and still meet their goals of a healthy, environmentally friendly, and sustainable diet.

If you are eating a typical American diet or one of the fad diets that encourage meat consumption, you are probably wondering how you can ever make such drastic changes to your diet. The answer is “one step at a time.”  If you have read my books “Slaying The Food Myths” or “Slaying the Supplement Myths,”  you know that my wife and I did not change our diet overnight. Our diet evolved to something very close to the Planetary Diet over a period of years.

The Commission also purposely designed the Planetary Diet so that you “never have to say never” to your favorite foods. Three ounces of red meat a week does not sound like much, but it allows you a juicy steak once a month.

Sometimes you just need to develop a new mindset. As I shared in my books, my father prided himself on grilling the perfect steak. I love steaks, but I decided to set a few parameters. I don’t waste my red meat calories on anything besides filet mignon at a fine restaurant. It must be a special occasion, and someone else must be buying. That limits it to 2-3 times a year. I still get to enjoy good steak, and I stay well within the parameters of the Planetary diet.

Develop your strategy for enjoying some of your favorite foods within the parameters of the Planetary Diet and have fun with it.

The Bottom Line

 

Is your diet destroying the planet? This is not a new question, but a recent commission of international scientists has conducted a comprehensive study into our diet and its effect on our health and our environment. Their report serves as a dire warning of what will happen to us and our planet if we don’t change our ways.
