Sport Specialization

Q:
There is pressure to have our elementary age children specialize (focus) on a single sport.  Is there research on this topic?

A:
Over the last 25 years, specializing in a single sport at a young age has become more and more common.  The reasons for specializing vary but the most common reason cited is the fear of a child falling behind kids that are participating in a structured single sport program.

Early research on this topic provided inconclusive answers.  Recent research has found many negative effects on children specializing in a single sport.  These include:

  1. Children specializing in a single sport account for 50% of overuse injuries
  2. Early specialization leads to burnout and inactivity as an adult
  3. Early specialization is a predictor of future injury. A Loyola University study found specialized athletes are 70% to 93% more likely to be injured than children who played multiple sports
  4. Early specialization results in higher stress levels and lack of enjoyment

Beyond the negatives, the following benefits arise from early multi-sport participation:
  1. Better decision making, pattern recognition, and increased creativity
  2. Better overall motor/athletic development and sport skill transfer
  3. Increased motivation, ownership of the sports experience, and confidence

A final topic to note:  Research also found that unstructured “free play” is important.  As “free play” provides a high level of enjoyment, increases motor skills, emotional ability, creativity; and results in greater sport engagement.

Protein Consumption

Q:
Can you consume too much protein?  Is it dangerous?

A: 
According to a study published in the Journal of Nutrition, on average, Americans consume between one-and-a-half to two times more protein than the daily recommended intake established by the World Health Organization.

It is also common for athletes and bodybuilders to believe a higher protein diet is critical to achieve peak performance or results.  In reality, the athletes or bodybuilders are either already getting enough protein or their higher protein needs are being met with the higher caloric diet required to meet the caloric demands of the activity.

Is it dangerous? More research is needed on this subject, but in general:

1)      In most cases, you do not need more protein or a protein supplement.
2)      Diets with a healthy mix of lean non-processed animal protein and plant protein (grains, vegetables, legumes) are best.
3)      Some research has indicated that high protein diets are linked to kidney disease, prostate cancer, and colon cancer.
4)      Diets higher in animal protein or with fatty or processed animal proteins have a higher risk to the diseases listed above as well as heart disease.

The Impact of Air Conditioning on Health

Q:
During the hot days of summer, is spending too much time in air conditioned buildings bad for your health?

A:
Numerous institutions and scholars list air conditioning as one of the greatest achievements of the 20th century.  They are widely used in westernized countries and global use is growing rapidly, but is it bad for you?

Below are the common positives and negatives impacts on health:

         Positive: Combat heat related illnesses (heat stroke). According to the Centers for Disease Control and Prevention, air conditioning is the number one protective factor against heat-related illness and death.  Age groups most susceptible are children under 4 and adults over 65.

         Positive: Helps manage allergies and asthma. Air conditioning can help filter out airborne pollen.  It also lowers indoor humidity, which in-turn decreases the growth of dust mites or mold.

         Negative: Mold and fungus. If regular maintenance and air filter changes do not occur, air conditioning can be a breeding ground for bacteria and fungus due to the moisture that accumulates in the evaporator coils.

         Negative: Weather acclimation/exercise.  Never venturing out in hot weather will prevent acclimation to the heat thus causing us to stay inside even more.  The more time spent inside the more likely the person is to be sedentary.

Blood Thinners

Q: 
How do “blood thinners” reduce blood viscosity?

A: 
Blood Thinners have no impact on the viscosity (thickness) of blood.  Instead, blood thinners prevent the blood from clotting or existing clots from getting larger.  They do not dissolve existing clots.

Blood thinners fall into two categories:  anticoagulants and antiplatelets. Anticoagulants, such as heparin, lengthen the time it takes to form a clot.  Antiplatelets, such as aspirin, prevent blood cells called platelets from clumping together to form a clot.

Blood thinners are prescribed to treat some types of heart disease, to those with a higher risk of stroke, or a higher risk of clotting. 

Although beneficial, blood thinners may increase the risk of serious bleeding due to cuts or injuries.  Our first line of defense should be proper nutrition and exercise to combat diseases.

Burning Sensation in Lungs During Exercise

Q:
What causes my lungs to have a burning sensation during exercise?

A:
At some point in our lives, we all have experienced a burning sensation in our lungs or airway while we were exercising.  What causes this feeling?
         Fitness level/activity intensity - If you are new to exercise, coming off a layoff, or increasing the activity’s intensity level you will tax your respiratory system.  When you tax your respiratory system, you breathe through your mouth and not your nose.  Mouth breathing will dry the mucus membranes and can result in a burning sensation.

         Air temperature/dry air - Cold air can be uncomfortable, but the air is warmed to body temperature before it reaches the lungs.  The burning sensation when exercising in cold temperatures is due to the fact that cold temperatures have dry air.  Dry air aggravates the lungs and airway and can lead to a burning sensation.

         Illness - Acute conditions that originate in or affect the lungs or airways (bronchitis, pneumonia) have a burning sensation associated with the illness.  Exercise may intensify the feeling.

         Environmental – Exercising in an environment heavy in irritants or pollutants will have a negative impact on the respiratory system and may lead to a burning sensation.

         Chronic Respiratory Disease – Chronic diseases, such as exercise-induced asthma, result in the airway constricting during exercise and can lead to a burning sensation.

WebMD Magazine "Training Day" Article


The June 2016 issue of WedMD magazine published an article by Kara Mayer Robinson in its “Living Healthy” section highlighting the importance of adding weekly strength training to your exercise regimen.  Not only does the article touch on important benefits of strength training, such as increased muscle and bone strength, improved posture, reduction to the likelihood of injury, and improved metabolism, but it also provides a solid list of recommendations for optimizing your results.  The purpose of this post is to provide a summary of these recommendations, as many of them fall in line with the training philosophies here at Fitness First. 

Target Every Zone- In order to reduce the likelihood of muscle imbalances and posture problems, it is important to aim for two to three strength training sessions a week targeting every muscle group.  This will ensure proper muscle symmetry and balance, as well as provide attention to any muscle groups that may be lacking. 

Focus on Form- At no point during an exercise should form be compromised to achieve more repetitions.  Fitness First focuses on the importance of quality movements as opposed to focusing on the quantity of movements.  This ensures a safe, efficient, and effective approach to strength training.

Add Weight Without Compromising Form- Progression is an importance aspect of achieving your desired results from strength training.  An appropriate resistance should be utilized for every activity until a desired repetition range can be achieved without compromising form.  Adding resistance gradually and sensibly is a good rule of thumb.

Take Time Off- Strength training causes micro-trauma to muscle tissue and it requires rest and recovery to repair itself.  This tearing of the muscle tissue and repairing process is what leads to increases in muscle strength.  Aim for at least 48 hours betweens training sessions. 

Don’t Hold Your Breath- It is important to maintain a normal breathing pattern as you perform any strength training exercise.  This will help ensure optimal delivery of oxygenated blood to the muscles during activity.  It also helps reduce issues related to hyperventilation, which can lead to the premature termination of an exercise due to central nervous system defense mechanisms. 

Don’t Go Fast- We’ve been saying this all along at Fitness First! This article gets it right by saying that slow, controlled movements are better, no matter the type of resistance being used.

Don’t Quit Too Soon- The article hits the nail on the head with this tip.  Performing repetitions until you cant do any more with good form is imperative for maximizing a training session.  Training to “failure” or fatigue means an adequate stimulus has been provided to the muscle tissue for it to adapt, rebuild, and ultimately get stronger.  That is the purpose of strength training, right?

Don’t Fall Into a Rut- Mixing things up periodically is important to navigate around boredom and burnout during exercise.  It is easy to create habits, but eventually new challenges are needed both physically and mentally.  At Fitness First, we address this by alternating workouts so that not every session is exactly the same.  After 20 sessions, we redesign a client’s exercise prescription, providing variety with equipment, activities, and overload protocols.  We take input from the client for activity selection and use our expertise to design routines that provide a comprehensive approach to total-body strength training.

The WedMD magazine article highlights many important strength training recommendations.  The bolded points above are cornerstones to the training philosophy at Fitness First.  All of these guidelines form a foundation for training safely, efficiently, and effectively.

June is National Dairy Month

June is National Dairy Month!

"National Dairy Month is a great way to start the summer with nutrient-rich dairy foods. From calcium to potassium, dairy products like milk contain nine essential nutrients which may help to better manage your weight, reduce your risk for high blood pressure, osteoporosis and certain cancers. Whether it's protein to help build and repair the muscle tissue of active bodies or vitamin A to help maintain healthy skin, dairy products are a natural nutrient powerhouse. Those are just a few of the reasons that you should celebrate dairy not just in June, but all year long."
-International Dairy Foods Association


Are you aware of these other dairy facts?
1. An eight-ounce glass of milk, one-ounce of most cheeses and an eight-ounce container of yogurt have as much protein as one egg.
2. Yogurt contains live and active cultures, or probiotics. Probiotics can help maintain a healthy digestive system.
3. Cheese contributes high-quality protein as well as calcium, phosphorus and vitamin A to the diet.
Now that you know, kick off your summer with nutrient-rich dairy foods and put your new knowledge to work for your health!

Fitness Level and Sweating

Q:
How does fitness level impact the amount that a person will sweat?

A:
There are a number of factors that determine how much sweat a person will produce.  Some of these factors include:  gender, body composition, number of sweat glands, skin surface area, environmental conditions, and genetics.

Another factor is fitness level.  People that are in better shape are capable of sweating more and generally do.  The reason people in better shape are capable of sweating more is due to the fact that their higher fitness level allows them to do more physical work.

The more work you do, the more heat your body generates, and the more sweat you will produce to regulate body temperature.

Facial, Mouth, and Head Injuries

Q:  Why is spring considered the worst time of the year for facial, mouth, and head injuries?

A:  Spring is the worst time of year for these injuries.  As a matter of fact, April is National Facial Protection Month.  April was named National Facial Protection month and is sponsored by several Sport and Dental associations due to the large number of injuries from people getting outside and participating in outdoor activities.

Research by the American Academy of Pediatric Dentistry’s Policy on Prevention of Sports-related Orofacial Injuries found that 10% to 39% of all dental injuries in children are related to sport injuries. Research also found that three of the five most common causes of childhood injuries are bicycling, playgrounds and soccer.

Most of the injuries could have been prevented or minimized by following the below guidelines:

        Use a mouth guard to protect your teeth.
        Wear a helmet.  Not just for sports like football or hockey.  Wear when playing sports such as softball, baseball, bicycling, and skateboarding.
        Ensure for proper vision (20/20) and wear protective eye gear.
        Use face shields to protect your face from flying objects and balls.
        Be alert.  Be conscience of your surroundings and minimize distractions.

The Drug-Food Interaction

Q:
Why shouldn’t you eat or drink certain citrus fruits while taking certain medications?

A:
Grapefruits, Seville oranges, Tangelos, and the juices made from them have many health benefits, but they can also interfere with some prescription and non-prescription medications.

The interference is generally called drug-food interaction.  Specifically, the fruits and juices speed up the rate of absorption in the body.  With a faster rate of absorption, the drug enters the bloodstream more quickly.  Abnormally high drug levels can have negative side effects on the body and negatively impact the performance of the drug.

It is believed that a natural chemical found in the fruit blocks the enzyme in the body that regulates the drug absorption rate.

The drugs impacted most are the prescription drugs used to lower cholesterol, known as Statins.  However, not all Statins are impacted the same.  Statins that are taken orally, such as Lipitor, are impacted the most because the drug-food interaction occurs in the digestive tract.

Negative side effects of the drug-food interaction may include the following:
        muscle breakdown
        liver damage
        digestive problems

Drug-food interactions are well known and patients should be provided guidance with the applicable prescriptions.

What causes a side ache when running or swimming?

Q:  What causes a side ache when running or swimming?

A:  Side ache refers to the nagging abdominal pain that tends to result from running or swimming.  The scientific term, "exercise-related transient abdominal pain" (ETAP), has plagued exercise enthusiasts for centuries and yet there is still no definitive explanation to the cause of the pain.  Below are the three leading theories:

Drinking before exercise - One recent study found people that consumed reconstituted fruit juices and beverages that were high in carbohydrates before exercise were prone to get ETAP.  ETAP didn’t seem to be related to the volume of the beverage consumed.

Diaphragmatic ischemia - During exercise, blood flow is increased to the working muscles and reduced to other parts of the body.  The theory suggests that the decreased blood flow (ischemia) to the diaphragm (muscle which expands your lungs for breathing) causes localized pain.  However, recent studies have found that runners prone to ETAP had no difference in inhalation strength compared to non-prone runners.  The findings imply that poor blood flow to the diaphragm was not a major cause of ETAP.

Ligament irritation - This theory suggests impact during exercise pulls the organs in your abdomen down, putting stress on the ligaments in the upper abdomen and results in pain.  However, side aches affect up to 75% of swimmers. Swimming does not involve the up-and-down strain found in running. Therefore, the up-and-down strain does not fully explain the origin of all ETAP.

Several theories exist, but they all have some short comings.

The Health Benefits of Eating Oatmeal

Q:  January is National Oatmeal Month.  What are the benefits of adding oatmeal to your diet?

A:  Each month the Whole Grains Council recognizes a staple of the worlds’ grains.  January is Oatmeal’s month because more oatmeal is purchased in January than any other month of the year.  The main reasons for this behavior are fewer fruits and vegetables are in season and people create a new year’s resolution to eat healthier.

Eating oatmeal has many health benefits.  Below are some of the many benefits or potential benefits:

        Helps lower LDL "bad" cholesterol and may help reduce the risk of heart disease.
        May help lower blood pressure.
        May help reduce your risk of type II diabetes due to the soluble fiber helping control blood sugar.
        Oats are high in beta-glucans, a starch that stimulates the immune system.
        Early introduction of oats in children's diets may help reduce the risk of asthma.
        Higher in protein and healthy fats, but lower in carbohydrates compared to other grains.
        Contain anti-oxidant and anti-inflammatory characteristics.
        Other grains have their bran and germ removed.  Oats almost never have the bran and germ removed; meaning the whole grain is present.  Australian researchers found oatmeal rated #1 among breakfast foods for making you feel full and rated #3 for making you feeling satisfied.

Even though January is National Oatmeal Month, it is important to remember the many health benefits of including oats and oatmeal in a balanced diet year-round.

Cool and Warm Season Vegetables

Q:
Do some vegetables grow better in cool weather?  If so, does the cooler weather limit their nutritional value?

A:
Vegetables generally fall into two categories:  cool season and warm season.  As the names imply, cool season vegetables have adapted to cool climates and grow best in temperatures below 70 degrees Fahrenheit. Warm season vegetables have adapted to warmer climates and must be planted when night temperatures stay above 45 degrees Fahrenheit.

Since cool season vegetables grow best in cooler temperatures, the vegetable’s appearance, nutritional value, and flavor are at their peak when their growing season remains below 70 degrees.  When temperatures rise about 70 degrees in late spring and summer, the vegetables start producing seed stalk and they develop a woody/bitter flavor.

Here in Minnesota, we have the opportunity to grow cool season vegetables in the spring and in the fall.  Cool season vegetables tend to be leafy or root vegetables and include cabbage, carrots, broccoli, spinach, onions, radishes, lettuce and turnips.  Some cool season vegetables can tolerate some frost and will continue to grow even when temperatures are in the low 40’s, which allows some vegetables to be harvested into  October.
