Like many of you, I have always enjoyed the outdoors...walking, running, biking, hiking etc. However, recently, I have been more concerned about being safe, (getting older and more cautious, distracted drivers) when doing these activities on the side of the road.

Almost 15 percent of all motor vehicle injuries to people happened to those not in cars but while walking, running or hiking, so one needs to be safe. In fact, over 4,000 walkers or runners were fatally hit by a motor vehicle according to the Centers for Disease Control (CDC). These statistics continue to increase as the number of distractions to drivers increases (phone calls, texts, etc). Consequently, walkers, runners and cyclists must be more aware than ever to prevent injury from motor vehicles and stay safe.

Five high risk factors for walkers, runners and cyclists:

• After dark
• At rush hour in high traffic
• Walk or run “with” instead of “into” traffic flow
• More than one other person with you
• Headphones

 “Runner’s World” offers the following recommendations to stay safe:

• Leave word. Tell somebody or leave a note at home about where you plan to go and how long you plan to be out. That way your loved ones will know to come look for you if needed.
• Protect yourself: If your route is in a high crime area, avoid dawn and dusk, carry self-defense spray, exercise with a partner, leave jewelry at home and vary your route and routine.
• Identify yourself. Run with proper ID, and carry a cell phone with emergency contacts taped to its back.
• Pretend you're invisible. Don’t assume a driver sees you. In fact, imagine that a driver can’t see you, and behave accordingly.
• Face traffic. Except for cyclists, walking and running “into” oncoming traffic is best. It’s easier to see, and react to, oncoming cars. And cars will see you more clearly too.
• Make room. If traffic gets heavy, or the road narrows, be prepared to move onto the sidewalk or shoulder of the road. When walking or running into traffic, stay as far left as possible. When biking, favor the far right side of the road.
• Be seen. Wear high-visibility, brightly colored clothing. When out near or after sunset, reflective materials are a must. (If you don't own reflective clothing, a lightweight reflective vest is a great option.) And use a headlamp or handheld light so you can see where you're going, and drivers can see you. The light should have a bright LED (drivers see blinking red as a hazard).
• Unplug your ears. Avoid using iPods or wearing headphones—you need to be able to hear approaching vehicles. If you do use headphones, do so with the volume low and just one earbud in.
• Watch the hills. When they crest hills, drivers' vision can suddenly be impaired by factors like sun glare or backdrops.
• Beware of high-risk drivers. Steer clear of potential problem areas like entrances to parking lots, bars, and restaurants, where there may be heavy traffic.
• Watch for early birds and night owls. At odd hours be extra careful. Early in the morning and very late at night, people may be overtired and not as attentive.
• Mind your manners. At a stop sign or light, wait for the driver to wave you through—then acknowledge with your own polite wave. That acknowledgement will make the driver feel more inclined to do it again for the next walker or runner. Use hand signals (as you would on a bicycle) to show which way you plan to turn.

CYCLISTS -

• Stay on the right and obey traffic rules.
• Wear a helmet
• Use hand signals when turning
• Wear visible clothing and have reflectors on your bike
• Carry a tire patch and first aid kit
• Maintain your bike
• Watch for pedestrians, parked cars, loose gravel and cracks and potholes.

The 27^th Steamtown Marathon is three months away and, despite the warm weather, many local runners are deep into training. With serious heat waves of summer, any prolonged endurance activity in minimal to moderate heat can be dangerous if not prepared. Adequate hydration is critically important, not only to those training for a marathon but also for other outdoor endurance activities such as cycling, hiking, long distance power walking, etc

Next to oxygen, water is the nutrient most needed for life. A person can live without food for a month, but most can survive only three to four days without water. Even though proper hydration is essential for health, water gets overlooked as one of the six basic nutrients. Dehydration occurs when the amount of water taken into the body is less than the amount that is being lost. Dehydration can happen very rapidly (i.e. in less than eight hours); the consequences can be life threatening and the symptoms can be alarmingly swift.

In the body, water is needed to regulate body temperature, carry nutrients, remove toxins and waste materials, and provide the medium in which all cellular chemical reactions take place. Fluid balance is vital for body functions. A significant decrease in the total amount of body fluids leads to dehydration. Fluids can be lost through the urine, skin, or lungs. Along with fluids, essential electrolytes, such as sodium and potassium, are also perilously depleted in a dehydrated individual.

The risk of dehydration is not limited to endurance athletes and outdoor enthusiasts. Dehydration is the most common fluid and electrolyte disorder of frail elders, both in long term care facilities and in the community! Elders aged 85 to 99 years are six times more likely to be hospitalized for dehydration than those aged 65 to 69 years.

Is water adequate to prevent dehydration? Will a sports drink improve my performance? While some answers to these questions apply generally to all, others vary according to the temperature, humidity, length of time and intensity of the activity and condition of the athlete. 

Proper hydration is essential for the comfort and safety of the recreational and serious athlete. Hydration is critical to maintain cardiovascular function, body temperature and muscle performance. As temperature, humidity, intensity, and duration of exercise increase, so too does the importance of proper hydration. Excessive sweating can lead to a loss of blood volume which requires the heart to work much harder to circulate you blood through your body.

Dehydration is a major cause of fatigue, loss of coordination, and muscle cramping leading to poor performance. Prehydration, (drinking before exercise) is the first step in preventing dehydration. Marathon runners, other long-distance runners, and cyclists often prehydrate1-2 days before a big event. Rehydration, (drinking during or after exercise) is the second step in preventing dehydration. While athletes may be more vulnerable to dehydration, all persons engaging in exercise would benefit from increased performance, delayed muscle fatigue and pain by maintaining adequate hydration. Proper prehydration would include drinking 12-16 ounces of water 1-2 hours before exercise.  Athletes with other health issues should consult their family physician before engaging in long distance endurance sports.

American College of Sports Medicine Hydration Recommendations:

• Eat foods high in carbohydrates and low in fat. Drink plenty of fluids between exercise sessions. The best fluids are plain water or fluids without sugar, caffeine or alcohol.
• Drink 17 oz or 2+ cups of fluid 2 hours before exercise
• Drink every 15 minutes during exercise.
• Keep drinks cooler than the air temperature. Drinks should be readily available.
• If you exercise more than 60 minutes, you may benefit from a sports drink containing a carbohydrate. The carbohydrate drink should not exceed 8% solution
• If you exercise more than 60 minutes, take 30-60 grams of carbohydrate per hour to delay fatigue and fuel muscle contractions.
• If you exercise more than 60 minutes, include (.5-.7 g per gallon) sodium in your drink of choice. This will also encourage additional drinking.
• Drink 24 ounces of water for every 2 pounds you lose after your workout. This is based on pre and post exercise weight.
• If you exercise more than 90 minutes, sports drinks may be helpful. 60 to 100 calories per 8 ounces of drink will help supply the needed calories for performance.
• Avoid caffeine. While the energy is good, it acts as a diuretic to rid the body of fluid. This is counterproductive for the high-level athlete.

Fall is here, cross-country running season has begun and the 26^th Steamtown Marathon is only a few weeks away! With that in mind, running injuries, some very specific to women, are on the increase…

While driving to or from work have you noticed more local running enthusiasts in the past few years? Moreover, have your noticed that most of the runners are women? Scranton Running Company has contributed to NEPA’s participation in a national trend; more women are engaged in running than men! Female runners account for 9.7 million runners (57%) while 7 million males run on a national level.

With this surge, the female runner has been subjected to a host of related injuries, including shin splints, which often lead to stress fractures. New research has found that stress fractures may be related to the loss of weight and body mass associated with the sport.

A recent study from Ohio State University found that female runners with a Body Mass Index (BMI) below 19 may have a higher risk of developing stress fractures than women with a BMI of 19 or above. Furthermore, the study also found that these women took longer to recover from these injuries.

According to Timothy Miller, MD, “When body mass index is very low and muscle mass is depleted, there is nowhere for the shock of running to be absorbed other than directly into the bones. Until some muscle mass is developed and BMI is optimized, runners remain at increased risk of developing a stress fracture,”

The study also found that female runners with a BMI of 19 or higher with severe stress fractures required 13 weeks to recover from their injuries and return to running. Runners with a BMI lower than 19, however, took more than 17 weeks to recover.

They concluded that women should know their BMI and consult with a medical professional to maintain a healthy number. Additionally, women should cross-train and include resistance training to improve the strength and muscle mass of the lower extremities to prevent injury.

The current BMI wisdom, according to the National Institutes of Health, is 19.8 for men and 24 for women, however, strong and competitive women tend to have a BMI of 26. A BMI of 18 is considered malnourished.

What is BMI?

Body mass index (BMI) is a measure of body fat based on height and weight of adult men and women over 20 years of age, according to the National Institutes of Health.

BMI = (weight in pounds / height in inches squared) X 703)

Example 1: a person who weighs150 pounds and is 68 inches (5 feet 8 inches) tall has a BMI of 22.8

Example 2: a person who weighs 110 pounds and is 66 inches (5 feet 5 inches) tall has a BMI of 17.7

Underweight      < 18.5%

Normal weight      18.5 to 24.9%

Overweight      25 to 29.9%

Obesity            30 and over

What is a stress fracture?

A stress fracture is fatigue damage to bone with partial or complete disruption of the cortex of the bone from repetitive loading. While standard x-rays may not reveal the problem, a bone scan, and MRI will. It usually occurs in the long bones of the leg, mostly the tibia (shin bone) but also the femur (thigh) and foot. Occasionally, it occurs in the arm.

Who is at risk for stress fractures?

FEMALE RUNNERS WITH BMI LOWER THAN 19 – is a primary risk factor.

10-21% of all competitive athletes are at risk for stress fractures. Track, cross country and military recruits are at greatest risk. Females are twice as likely as males to have a stress fracture. Other athletes at risk are: sprinters, soccer and basketball players, jumpers, ballet dancers are at risk in the leg and foot. Gymnasts are also vulnerable in the spine while rowers, baseball pitchers, golfers and tennis players can experience the fracture with much less frequency in the ribs & arm.           

The problem is much more prevalent in weight bearing repetitive, loading sports in which leanness is emphasized (ballet, cheerleading) or provides an advantage (distance running, gymnastics).

Stress fractures usually begin with a manageable, poorly localized pain with or immediately after activity such as a shin splint. Over time, pain becomes more localized and tender during activity and then progresses to pain with daily activity and at rest.

Other Causes of Stress Fractures

• Overuse, Overload, Over training – is the number one cause. Running too many miles with too much intensity with too much frequency is the perfect formula.
• Inadequate Fitness Level – or activity level prior to the stress fracture. For example, the high school runner takes the summer off and then quickly accelerates his/her program to quickly for cross-country in August/September.
• Poor Biomechanics – when your feet hit the ground the forces are absorbed and transferred to the rest of the body. If the biomechanics of feet are not perfect, then the forces are not absorbed and another body part bears too much force. For example, flat or pronated feet poorly absorb the shock and pull the tendons of the foot and shin.
• Recent Change in Training Schedule – sudden increased intensity or speed
• Recent Change in Running Surface – sudden change to a hard or soft surface
• Recent Change in Footwear – shoes too hard or too soft, too much control or too little control, too much pronation or too much supination
• Overweight – running with an extra 10 pounds and attempting to return to running as a method of weight loss
• Underweight – the underweight female athlete is at high risk for stress fractures. If underweight and have a history of menstral irregularities or and eating disorder, the risk of stress fracture increases significantly
• History of Stress Fractures – makes the athlete two times as likely to have another

Prevention & Treatment

• Maintain Ideal BMI – 24 for female runners
• If Overweight – gradual exercise with diet, not too much too quickly - Mix run & walk every 10 minutes
• If Underweight – improve diet maintain healthy body fat%
• Alternate Training – cross train with non-weight bearing activities: bike, swim, elliptical
• Perform lower body weight training – to strengthen the muscles of the lower body, thighs, knees, ankles, feet.
• Gradually Build Up Fitness Level – wean into activity 1-2 miles, then add ½ mile at a time
• Correct Biomechanics - Orthotics, Running shoes, see a Podiatrist
• Gradual Change in Training Schedule
• Gradual Change in Surfaces – ½ run on soft surface, ½ run on hard surface
• Gradual Change in Foot ware – walk in new shoes first, then run 1-2 miles
• Consult Family Physician/Orthopedic Physical Therapist/Nutritionist

“The woods are lovely, dark, and deep,

But I have promises to keep,

And miles to go before I sleep,

And miles to go before I sleep.”  Robert Frost

The purpose of this column is to present an alternative to traditional running that will allow training on more interesting and less stressful surfaces such as those used when hiking, mountain biking and horse riding trails in the beautiful woods of Northeast Pennsylvania…”trail running!”

I remember my trail running days with fondness. One day, when the temperatures soared above 90 and my wife pleaded with me to avoid running in the heat (she was wise), as a typical runner, I needed hit the road. As I set out on State Road 348 just on the periphery of Lackawanna State Park in Dalton, the sun was beating down on me. I happened to see a sign that read, “Orchard Trail, Bull Hill Trail, Tree Line Trail.” I thought it might be a good idea to find some shade and decided to run on this path normally used for hiking, mountain biking and horseback riding. It turned out to be a great decision. While I was forced to run 25% slower due to the uneven terrain (rocks, tree roots, stumps), I was able to practice “light running” techniques by running with short strides on the balls of my feet. I felt much more refreshed as I avoided the direct sunlight under the cover of the trees.

Furthermore, I enjoyed the up close view of nature as I ran by cool streams and wet mossy rocks. I saw beautiful flowers, rhododendron, and mountain laurel. I observed deer, chipmunks and birds. In my quest to avoid the hot sun, I discovered the beautiful underworld of “trail running” – a growing trend in today’s running community. If you, like me, enjoyed pounding the pavement for many years, trail running can help you rediscover why you love to run. It is beautiful, peaceful, natural and unique. It is fun to get in touch with your inner child as you run in the woods and get muddy. Trail running makes running fun…and it’s good for your joints!

The trail running community purports that trail running is popular because it satisfies a primal need for man to move through nature, derived from hunter/gatherer days. Others who promote trail running feel the popularity is due to the many advantages it offers. One, trail running prevents impact injuries due to soft surfaces. Two, the training style of running with shorter strides on the ball of the foot, lessens impact. Three, this type of running will develop stronger ankles and trunk core muscles while improving balance, coordination and proprioception from running on uneven surfaces. Lastly, the ability to release copious amounts of endorphins while breathing fresh air instead of roadside fumes is invaluable.

Trail Running Gear

• Clothing - Trail running clothes can be the same as those worn for road running except be sure you don’t mind if they get dirty and a little torn or snagged.
• Shoes – While you can begin trail running in the same shoes you road run in, you will find that a different pair is necessary due to excess dirt and water. Also, if you decide to get into trail running, it is worth purchasing trail shoes which are stronger, more water proof and offer better traction.
• Water – a hand held water bottle or a water bottle belt is essential. The belt offers little pouches for money, keys, ID, and power bars for longer runs.
• Insect Repellent - a must for mosquitoes and ticks! 
• Headlamp – necessary for evening runs because it gets very dark in the woods. Also, it gets dark earlier in the woods than on the roads and you need to see the terrain clearly.
• Change of Clothes – it is a good idea to have a first-aid kit, towel and change of clothes in your car to change into before you drive home.
• Cell Phone – just in case of an emergency.

Tips to Begin Trail Running

• Find a Trail – Start by asking around. Hikers, mountain bikers, and horseback riders are a good start. The American Trail Running Association has a website with a free directory of trails in the United States. PA State Parks such as Lackawanna State Park in Dalton, offer many options (www.visitPAparks.com) or download the app AllTrails. Learn the difference between “non technical trails” which are wider with a paved, dirt or gravel base and much easier than “technical trails” which are narrow, rocky, hilly and challenging.
• Run Slowly – To be safe, run 25% slower when running a trail in the woods. Use a short stride and land on the ball of your foot. Forget about the pace, feel the dirt under your feet, work on balance and stability. It is a different type of running.
• Walk – Don’t hesitate to walk when necessary, especially up rocky and slippery hills.
• Keep Your Eye on the Trail – Pay careful attention to the terrain by looking 5 to 10 feet ahead.
• Anticipate Slippery Rocks and Stumps - Pick your feet up higher and bend your hips and knees more when necessary to avoid tripping over a log. Walk over obstacles if necessary.
• Keep a Distance – Don’t crowd the trail. You may have to share it with other runners, bikers and hikers. Pass with care.
• Be Safe/Be Prepared– Remember the first-aid kit, cell phone, extra clothes and food in the car and make sure someone knows where you plan to run. Run with a friend.

PREVENTION OF RUNNING INJURIES

It is two months away from the 25^th Steamtown Marathon. This column is dedicated to those dedicated runners preparing for the big day, Sunday, October 9, 2022.

Congratulations and thank you to Bill King, founder and race director, and his band of brothers, for their tireless efforts organizing and sustaining a great race that instills pride for all people of NEPA. It has inspired many people, including me, to transfer the discipline and determination required to complete a marathon by overcoming challenges one mile at a time.

Now, a little marathon history: In 490 B.C. Phedippides, ran 25 miles from Marathon to Athens to deliver an important military message and died immediately. Ironically, the first marathon of the modern Olympic Games in 1896 in Athens was won by Spiridon Louis, a humble Greek peasant, who stopped along the way for a glass of wine and told the owner of the tavern that he would win the race. He was determined to pace himself properly, as he knew the dusty, hilly path better than anyone in the field. He was greeted with jubilation and become a hero and legend.

HOW TO PREVENT RUNNING INJURIES

Avoid the “terrible too’s”

• Avoid overtraining: number one cause of injury
  • Too much intensity
  • Too many miles
  • Too soon
  • Follow the 10% rule
    • Do not increase weekly mileage by > 10% each week

Only run miles needed to meet your goals

• Following the mantra that more must be better will lead to injury
• Accumulating “junk miles” causes the body to break down

Avoid inconsistent training

• Occurs when you have missed several sessions and you attempt to “catch up” by adding additional miles

Avoid repeating hard workouts without any easy workouts in between

• Do not run two hard workouts on consecutive days
  • Long runs
  • Hill repeats
  • Races
  • Speedwork
  • Allow for recovery, re-building and reduction of injury risk
    • Day of rest
    • Cross training

Consider cross training to avoid overtraining without compromising fitness level

• Reduces chance of injury
  • Balances muscle groups
    • Strengthens non-running muscles and rests the running muscles(Quadriceps and adductors)
  • Develops body parts that running neglects
  • Reduces stress on joints
    • Low-impact
    • Swimming
    • Water running
    • Cycling
    • Cross country skiing
    • Stair climbers
  • Maintain/improve cardiovascular fitness
    • Increases aerobic capacity
    • Burns additional calories
  • Avoids  boredom of running
    • Provides mental break from sport to avoid burn-out
      • Especially for the long distance events (marathons)
      • Try hiking!
  • Allows  continued training despite injury
    • Maintain fitness level while recovering from injury
    • Reduces frustration of inability to run

Treat your feet right

• Avoid worn out shoes
  • Most common cause of injury
  • Reduced shock absorption, cushioning and stability
    • Increases stress and impact
    • Muscle fatigue, shin splints and joint pain (especially knees) may be a signal
  • Replace every 300-400 miles
    • Dependent on running style, body weight and running surface
      • Smaller/lighter runners closer to 400
      • Heavier runners closer to 300
      • Running on hard surfaces
        • Replace shoes sooner than if running on treadmill
  • Record new shoe purchase
    • Calendar
    • Training log
    • Inside shoe
  • Purchase a second pair halfway through the life of the initial pair
    • Rotate shoes
      • Running in different shoes on alternating days provides even stress distribution on feet
    • Extends shoe life
    • Having a fresh pair as a reference
      • Will recognize when old ones need to be replaced
  • Shoe type
    • Most important piece of equipment
    •  Appropriate for foot type and weight
      • Flat foot: motion control
      • High arch: cushioning
    • Specialty running store
      • Scranton Running Co
    • Tennis shoes not appropriate
  • Biomechanical problem
    • Heel lifts or orthotics

Visit your doctor regularly and listen to your body.

Spring is just around the corner so it is time for running enthusiasts to lace up their sneakers, get outside and run! Runners are addicted to running for good reason. There is nothing like it! No exercise offers so much in such little time. For example, the caloric expenditure while running is higher than for most other exercises, including biking. Also, it allows for fresh air and beautiful scenery with a minimal investment in clothing or equipment.  It requires little skill and time to learn. Runners suffer from less depression, colds and flu symptoms, and experience less pain due to an endorphine release (natural chemical in the brain associated with euphoria and pain control) that is greater than found in other sports and activities. These are some of the motives that cause people to run every day, in spite of the constant loading and wear and tear on the joints.

To be a competitive runner and have longevity in the sport, optimal form is necessary. Moreover, a recent study shows that a runner can decrease the stresses on the lower body and reduce the incidence of stress fractures when trained to run with proper form using visual feedback while on a treadmill. The application of this information has significant implications for training programs for runners for the prevention and recovery from injury. One such low impact method is called the “Pose Running Technique,” by Dr. Nicholas Romanov. It is a “soft landing” method which promotes; an S-like body position with slightly bent knees, a slightly forward lean at the ankles to employ gravity and momentum, lifting the feet up under the hips, and landing on the ball of the foot under the body to absorb the center of mass.

It is my opinion, that the best runners, with the least injuries, such as Jordan Hoyt, speedster from Abington Heights, employ these techniques naturally. Additionally, many of the world’s best runners use coaches and trainers to assist them in their quest for success and injury prevention by using perfect form. However, for the rest of us, we must learn to maximize the efficient use of the body as it works with, not against gravity. We must learn to run “soft” to prevent injuries.

PROPER FORM

Head Position

A slight upward tilt of the head to allow a view of the horizon ahead should be most comfortable. Avoid looking down or up to extremes. Do not rock or rotate the head while running.

Shoulder Position

Loose and relaxed shoulders set the tone for a good run. Keep them level without tilting side to side or rotating left to right.  Avoid holding the shoulders in a tight and high position.  

Arms

Loose and relaxed arms also set the tone for a good run. A good arm swing is always in forward motion in a linear direction and stays between the waist and lower chest. Never clench the fist. Do not rotate or twist the arms across the body.

Torso

If the head, shoulders and arms are in correct position, then the torso will be upright. An erect running posture is necessary to promote efficient movement and breathing. The posture that you assume when taking a deep breath is the correct torso position for good breathing while running. 

Hips

The hips will follow the position of the parts above in a linear forward direction. However, if the torso leans forward because the head hangs down then the hips will tilt downward. If the arms swing and torso rotates side to side, then the hips will also rotate.

Legs/Stride

Sprinters need to lift the knees high to thrust the lower legs forward. Long distance runners cannot maintain a high knee lift for a long period of time, however, a slight knee lift with a shorter but quicker stride is more efficient. Proper running requires the foot to softly strike the ground with the knee slightly bent. If the knee is fully extended in front of the body upon impact, the stride is too long and the force too great.

Ankles/Feet

To excel as a runner, when the foot hits the ground it should land lightly, between the heel and the midfoot. The ankle is flexed and rolls quickly forward to the toes to push off the ground with maximum force. The calf muscle propels the runner forward. Efficient running has a quiet and springy landing. A loud foot slap on impact is a sign of poor form and results in excessive force transferred to the lower leg. The foot should spend as little time as possible in contact with the ground…thus a soft runner “floats” when they run.

OVERTRAINING CAN LEAD TO STRESS FRACTURES

After enduring the challenges of a cold and snowy winter, late spring and early summer is the time of year when long distance runners ramp up their training in preparation for the some of the best half and full marathons in the fall: Steamtown, Philadelphia, New York, Marine Corps in DC to name a few. But, runners beware; overtraining can lead to stress fractures.

I would like to introduce this topic with some marathon history. In 490 B.C. Athens was under attack by the Persians and was outnumbered more than two to one. The Athenians fought bravely and defeated the enemy in the town of Marathon to keep the intruders 26 miles away from their families in Athens. To keep the anxious citizens of Athens calm, leaders immediately ordered a foot soldier, Phedippides, to the capital to share the news. Phedippides ran, in full armor, for 26 miles from Marathon to Athens, delivered the message and died immediately. Now, people do the same thing of their own free will!

In the modern age, marathon and recreational runners enjoy testing their mental and physical stamina in pursuit of fitness and wellness. If not careful, many runners (and other competitive athletes) will develop pain in their shins (shin splints). Unfortunately, in many of these well-intended athletes, this problem can lead to a much more severe and advanced problem with shin splints called a stress fracture. Some very good athletes have been hindered by this problem.

What is a stress fracture?

A stress fracture is fatigue damage to bone with partial or complete disruption of the cortex of the bone from repetitive loading. While standard x-rays may not reveal the problem, a bone scan, and MRI will. It usually occurs in the long bones of the leg, mostly the tibia (shin) but also the femur (thigh) and foot. Occasionally, it occurs in the arm.

Who is at risk?

10-21% of all competitive athletes are at risk for stress fractures. Track, cross country and military recruits are at greatest risk. Females are twice as likely as males to have a stress fracture. Other athletes at risk are sprinters, soccer and basketball players, jumpers, ballet dancers are at risk in the leg and foot. Gymnasts are also vulnerable in the spine while rowers, baseball pitchers, golfers and tennis players can experience the fracture with much less frequency in the ribs & arm.           

The problem is much more prevalent in weight bearing repetitive, loading sports in which leanness is emphasized (ballet, cheerleading) or provides an advantage (distance running, gymnastics).

Stress fractures usually begin with a manageable, poorly localized pain with or immediately after activity such as a shin splint. Over time, pain becomes more localized and tender during activity and then progresses to pain with daily activity and at rest.

Causes of Stress Fractures

1. Overuse, Overload, Overtraining – is the number one cause. Running too many miles with too much intensity with too much frequency is the perfect formula.
2. Inadequate Fitness Level – or inadequate activity level prior to the stress fracture. For example, the high school runner takes the summer off and then quickly accelerates his/her program too quickly for cross-country in August/September.
3. Poor Biomechanics – when your feet hit the ground the forces are absorbed and transferred to the rest of the body. If the biomechanics of feet are not perfect, then the forces are not absorbed and another body part bears too much force. For example, flat or pronated feet poorly absorb the shock and pull the tendons of the foot and shin.
4. Recent Change in Training Schedule – sudden increased intensity or speed
5. Recent Change in Running Surface – sudden change to a hard or soft surface
6. Recent Change in Footwear – shoes too hard or too soft, too much control or too little control, too much pronation or too much supination
7. Overweight – running with an extra 10 pounds and attempting to return to running as a method of weight loss
8. Underweight – the underweight female athlete is at high risk for stress fractures. If underweight and have a history of menstral irregularities or and eating disorder, the risk of stress fracture increases significantly
9. History of Stress Fractures – makes the athlete two times as likely to have another

Treatment & Management

1. Alternate Training – cross train with non-weight bearing activities: bike, swim, elliptical
2. Gradually Build Up Fitness Level – wean into activity 1-2 miles, then add ½ mile at a time
3. Correct Biomechanics - Orthotics, Running shoes, see a Podiatrist
4. Gradual Change in Training Schedule
5. Gradual Change in Surfaces – ½ run on soft surface, ½ run on hard surface
6. Gradual Change in Footwear – walk in new shoes first, then run 1-2 miles
7. If Overweight – gradual exercise with diet, not too much too quickly. Mix run & walk every 10 minutes
8. If Underweight – improve diet maintain healthly body fat%
9. Consult Family Physician – Early management often involves immobilization, rest, pain medicine 4-6 weeks for healing. non weight bearing cross training such as the recumbent bike, swimming, elliptical.
10. Physical Therapy- Physical therapy modalities such as ultrasound, cold with electrical stimulation, biomechanical taping or orthotic supports, and exercises for foot, ankle muscles.

Visit your doctor regularly and listen to your body.
