The Negative Effects of Gatorade

Gatorade has long been a popular sports drink, especially for kids. It is marketed as an electrolyte replacement drink for athletes. Electrolytes are substances that contain free ions and conduct electricity1. In the human body, electrolytes are responsible for regulating nerve and muscle function, blood pH, hydration, blood pressure, and damaged tissue repair1. Some examples of electrolytes that are in our bodies are sodium, potassium, magnesium, and chloride1. The levels of electrolytes in our blood change when water levels in our body change, for example, during altered hydration status1. When we sweat, we lose mostly sodium and potassium, and they must be replaced in order to maintain the proper balance in our bodies1. According to ACSM, two pounds of sweat contain an average of 800 mg of sodium (ranges between 200-1600 mg) and 200 mg of potassium (ranges between 120—600 mg)2.

Gatorade has three different lines of sports drinks: G2, Gatorade Protein Recover, and Gatorade Thirst Quencher. All Gatorade products have a list of difficult-to-pronounce-ingredients, and many of these ingredients are forms of sugar or artificial sweeteners. In fact, sugar is the second ingredient after water; the ingredient list on a food label lists the ingredients in descending order of prominence and weight. Therefore, Gatorade products are mostly sugar and water. In fact, Gatorade Thirst Quencher has a whopping 14 g of sugar, coming mostly from sucrose syrup and glucose-fructose syrup. “The American Heart Association recommends that no more than half of your daily discretionary calorie allowance come from added sugars. For most American women, this is no more than 100 calories per day and no more than 150 per day for men (or about 6 teaspoons a day for women and 9 teaspoons a day for men)3.” This is about 24g of sugar for women and 36g of sugar for men.

Excessive sugar in the diet can be very bad for your health, and it is important to try to limit the amount of added sugar in your diet. Sugar that is naturally occurring in fruit and milk is perfectly fine; it is the added sugars that need to be decreased. Consumers need to beware because sugars are hidden in many different kinds of foods, such as salad dressings and crackers4.

One negative consequence of excessive sugar intake is weight gain and obesity. Sugar is very calorie dense, and as stated before, it is added to numerous foods and drinks4. Additionally, eating a lot of sugary foods displaces more nutritious foods in the diet, and these foods don’t provide the same satiety as healthful foods, and therefore cause overeating4. A second issue with added sugars is that they increase the risk for higher triglycerides, lower HDL, and higher HDL, which contribute to an increased risk of coronary heart disease4. Lastly, sugar contributes to tooth decay4.

The G2 line of Gatorade has fewer calories and less sugar; but it does have sugar alcohols instead. Sugar alcohols are a type of reduced-calorie sweetener5 that provides fewer calories than regular sugar. They do increase blood sugar levels, but less dramatically than regular sugar5. On a positive note, they do not cause tooth decay. Sugar alcohols can have some negative GI side effects, such as bloating and diarrhea6

Another huge problem with Gatorade is the amount of food additives and colorings added to the products. For example, one additive is monopotassium phosphate, which is not only used as a food additive, but also a as a fertilizer and fungicide7. It is a bit scary to be ingesting an ingredient used to fertilize plants. Additionally some flavors of Gatorade contain brominated vegetable oil (BVO), a food additive used as an emulsifier in drinks with citrus flavoring10. Bromine – part of BVO – is an element found in flame retardants9! Some research shows that it may build up in the body leading to thyroid problems, memory loss, and skin and nerve problems9. It has been banned in Japan and Europe10. In January 2013, Pepsico announced they had plans to remove BVO from Gatorade; however, there are no current plans to remove it from Mountain Dew10.

Gatorade is also filled with many food coloring, such as blue 1 and red 40. Many studies have showed a link between children and hyperactivity due to food additives11. In fact, 35 years of research has shown that many children with ADHD show significant improvement in their symptoms when they eliminate artificial food colors from their diet12.

Many popular athletes endorse Gatorade and some may use it to replace electrolytes during sporting events and training. Gatorade isn’t completely bad; it does replace sodium and potassium and help restore electrolyte balance and hydration status. Athletes are paid to endorse products, and they may not do their due diligence to find better and healthier alternatives.

A Better Alternative:
If you are looking for an electrolyte replacement drink, there are better alternatives available. Thorne Performance, a line of supplements geared towards athletes and their needs, has created, Catalyte, an electrolyte and energy restoration complex. Catalyte is all-natural and does not contain calories, sugar, additives, or caffeine. It is also gluten and soy free. Catalyte comes in a lemon lime flavor and the product is easy to mix. In fact, the Catalyte powder formula contains vitamins and minerals that, when mixed with pure water, makes a tasty electrolyte supplement that helps repair and rebuild muscle.

You can learn more about Catalyte and other Thorne Performance products on our website www.purefitclubnutrition.com. Again, there are other good products on the market, but Pure Fitness believes in the quality of the products at Thorne.4›

Pain Related to daily Activities

Our daily activities can actually cause muscle imbalances. No matter your line of work, you probably have some type of routine, repetitive activities. This can overwork some muscles and under-work others and is one reason many people often say, “I do not know how this happened. One day I felt pain but I’ve never had an injury.”

The body is a balanced system of levers and disrupting that balance can put joints at a mechanical disadvantage, causing unnatural and inefficient movements. The muscles that work harder tighten while the opposite weaker muscles lengthen causing impingement of joint spaces and other joint irregularities. This extra wear on the joints and ligaments can also cause arthritis, bulging disks and even tiny fractures in the spine. For example, an office worker who sits incorrectly all day with chin forward, shoulders rounded and leaning over toward the computer will likely have anterior shoulder, low back and neck pain. Think about the amount of times you get up and down in one day. If you are doing so incorrectly the force on your spine eventually will cause some type of break down. This postural distortion eventually can cause all sorts of problems such as pain, poor sleep, scar tissue build up and muscle atrophy, just to name a few. The problem is people go to the doctor and take medication for pain and are told to do routine, impersonal everyday exercises.

Unfortunately, medication can often be a mask that only exaggerates the problem and introduces new side effects. And general, routine exercises don’t fit every person. People have different lifestyles and do different things. One person may have back pain due to a hip dysfunction while another may have a thoracic issue so exercises need to be tailored to the individual.

An effective exercise prescription needs to not only consider your job but your daily activities and workout routine. Did you know stretching alone can alleviate most basic everyday complaints? Exercise and stretching related to daily activities can benefit any person because if you feel better at work you will perform better. If a job is stressful it can actually cause tension in the neck and back, and pain from tight muscles can trigger stress and thus the start of a cycle.

What Makes Up the Core

The foundation of your core is much more than just your abdominal muscles. It includes muscles that lie deep within your torso, right up to your neck, and your shoulders.  The core includes the following structures:

  •      Multifidus –A very deep muscle that runs from the neck (C3) to the lumbar spine (L5). Approximately two thirds of the static support in your back is produced through contraction of the Multifidus muscle.
  •      Interspinales, Intertransversarii, Rotatores – Deep structures that attach directly to the spinal column. These are very important for rotatory motion and lateral stability.
  •      Internal/External Obliques & Transversus Abdominis –These structures transmit a compressive force, and act to increase intra-abdominal pressure that stabilizes the lumbar spine.
  •      Erector Spinae – These muscles help to balance all the forces involved in spinal flexion.
  •      Quadratus Lumborum – This muscle stabilizes the  12th rib during respiration and laterally flexes the trunk.
  •      Thoracolumbar Fascia – This area supplies tensile support to the lumbar spine, and is used for load transfer throughout the lumbar region.

These muscles connect to the spine, pelvis, and shoulders to create a solid foundation of support.  When these core muscles are strong, flexible, and move freely, then the athlete is able to generate controlled, powerful movements in his/her arms and legs.

Imbalances Weaken Your Core

Training long hours does not guarantee that you have core stability.  In fact, spending too much time working within one plane of motion often creates core imbalances.  Add these imbalances to stresses caused by poor posture during running, and the repetitive motions of swimming, and you have an equation for the development of a weak core.

Often the athlete tries to correct these imbalances by heading to the gym to strengthen weakened areas.  Unfortunately, since many weight machines only work through one plane of motion (usually sagittal), these strengthening exercises only reinforce core instability.

Imbalances Affect Performance and Lead to Injury

Optimum posture is based on the attainment of a balance between primary muscle movers and their opposing muscles.  This is referred to as a force coupled relationship – when muscles act in opposition to each other to create a movement.  An imbalance is created when one muscle group is overworked in comparison to its opposing structure.

Most cyclists focus on their hamstrings, quadriceps, and gluteals and forget about the importance of core stability.

Consider how many hours the triathelete spends bent over in a flexed position on the aero bars, with no rotational or side bending motions. A strong core is needed to counter-balance these forces.

With a focus on the core, a cyclist can generate more power and can sustain a higher level of intensity for longer periods.

A stronger core also means less stress on the primary muscle movers and a delay in the build up of lactic acid.

Even minor changes such as brake position can affect core stability.

  • If the brake handle position is too low, the cyclist is forced to reach too far forward with their forearms.
  • This reaching position forces the cyclist to raise their head forcing the pelvic girdle posterior. This position cause a restriction in several key muscles in the core, thus reducing performance.
  • The ideal position for the forearms is to have the elbows bent and the forearms flattened out. In this position, the cyclist head drops into a more comfortable aerodynamic position, and the pelvis tilts forward. In this position, the cyclist is able to use all the core muscles with improved efficiency

Following the Kinetic Chain

Consider how the chronic shortening of just one muscle can affect performance and cause injuries.  There are multitude of different muscle groups we could focus on, but for our example we will chose the rectus abdominus muscle.

rectus abdominus is often shortened by doing crunches, hanging leg raises, or by spending an excessive amount of time bent over the aero bars.

The rectus abdominus attaches from the fifth to the seventh ribs.  As this muscle shortens, it has the effect of:

  •  Pulling the chest down and moving the shoulders and head forward.
  •  As the shoulders move forward, the arms and hands move inward (also called medial rotation).

If we follow the kinetic chain, what started as a shortening of an abdominal structures ends up affecting posture, shoulder rotation, arm position, and even the positioning of the hands.

Running

Now consider how a shortened rectus abdominus affects a triatheletes performance during running. Although opinions about the ‘ideal running form’ vary greatly, most authorities will agree that the less energy you expend, the more effective your running style.

The following table illustrates how an imbalance in the rectus abdominus decreases the runners ability to run efficiently.

Common running recommendations
(Runners World Online)
How a shortened rectus abdominus affects your running
Run upright. Your back should be straight, roughly at a 90-degree angle to the ground.

Look straight ahead. Your eyes should be focused straight down the road on a point moving about 10 meters in front of you. This helps to keep you in a straight line.

Swing your arms naturally. The angle at the elbow between your upper and lower arms should be about 90 degrees. Your hands should be loosely cupped, about belly level.

A shortened rectus abdominus will pull the runners posture forward. This causes a braking action that reduces running economy.

As the rectus is shortened, it pulls the chest forward and pushes the head down.  In order to look straight ahead as instructed, the athlete wastes a considerable amount of force in trying to overcome the contracted rectus abdominus.

As the shoulders move forward, a shortened rectus abdominus causes the arms to rotate internally. This makes keeping your arms relaxed at the recommended 90-degree angle much more difficult, again reducing running economy.

This is only one example. When performing a biomechanical analysis, it is very common to see numerous imbalances of which the athlete is completely unaware.

Protein in Your Diet

Proteins are complex organic compounds. The basic structure of protein is a chain of amino acids.

Function
Every cell in the human body contains protein. It is a major part of the skin, muscles, organs, and glands. Protein is also found in all body fluids, except bile and urine.

You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development during childhood, adolescence, and pregnancy.

Food Sources
Protein-containing foods are grouped as either complete or incomplete proteins.

Complete proteins contain all nine essential amino acids. Complete proteins are found in animal foods such as meat, fish, poultry, eggs, milk, and milk products such as yogurt and cheese. Soybeans are the only plant protein considered to be a complete protein.

Incomplete proteins lack one or more of the essential amino acids. Sources of incomplete protein include beans, peas, nuts, seeds, and grain. A small amount of incomplete protein is also found in vegetables.

Plant proteins can be combined to provide all of the essential amino acids and form a complete protein. Examples of combined, complete plant proteins are rice and beans, wheat cereal, and corn and beans.

Side Effects
A diet high in meat can contribute to high cholesterol levels or other diseases such as gout. A high-protein diet may also put a strain on the kidneys.

Recommendations
A nutritionally balanced diet provides adequate protein. Protein supplements are rarely needed by healthy people.

Vegetarians are able to get adequate amounts of essential amino by eating a variety of plant proteins.

The amount of recommended daily protein depends upon your age and health. Two to three servings of protein-rich food will meet the daily needs of most adults.
