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.

Several years ago, while hiking to the bottom of the Grand Canyon with my family, my wife Esther developed “canyon knee,” also known as “hiker’s knee” or in medical terms, “patellar tendonitis.” Regardless of the term, the end result was that she had severe pain in the tendon below her knee cap and was unable to walk up the trail to get out of the canyon. In addition to ice, rest, bracing, and non-steroidal anti inflammatory medications, the National Park Ranger insisted that she use two trekking poles on her ascent to the rim.

Prior to that experience, I always thought that “walking, hiking sticks or trekking poles” were for show or those in need of a walking aide. Well, I could not have been more incorrect. Needless to say, Esther made it out of the canyon safely and, with the use of our life saving trekking poles; we have lived “happily ever after!” Now, 15 years later, I rarely walk more than 5 miles without my poles.

As a result of this experience, I have been recommending walking or trekking poles to my patients. These poles are an essential part of hiking or distance walking gear, for the novice and expert alike. Specifically, for those over 50 who have degenerative arthritis and pain in their lower back, hips, knees, ankles or feet, these simple devices have been shown to improve the efficiency of the exercise and lessen the impact on the spine and lower extremities. Additionally, using poles reduces the likelihood of ankle sprains and falls during walking. Trekking poles are also a safe option for those with compromised balance. If you want to walk distances for exercise and need a little stability but don’t want the stigma of a cane, trekking poles are for you.

History of the Hiking Stick:

Early explorers, Europeans and Native Americans have been using walking sticks for centuries. More recently, in the 1968 classic hiker’s bible, “The Complete Walker,” Colin Fletcher praised his “walking staff” for its multipurpose use: for balance and assistance with walking and climbing, protection from rattlesnakes, and for use as a fishing rod. Today, these sticks are now versatile poles made from light-weight materials.

Trekking Pole Features:

Trekking poles are made of light-weight aluminum and vary in cost and quality. But, like most things, “you get what you pay for!” These hollow tubes can telescope to fit any person and collapse to pack in luggage for travel. Better poles offer multiple removable tips for various uses, conditions and terrains. For example, abasket to prevent sinking too deeply in snow, mud or sand; a blunt rubber tip for hard surfaces like asphalt or concrete, or the pointed metal tip to grip ice or hard dirt/gravel. Better quality poles offer an ergonomic hand grip and strap and a spring system to absorb shock through your hands, wrists and arms upon impact.

The poles should be properly adjusted to fit each individual. When your hand is griping the handle the elbow should be at a 90 degree angle. Proper use is simple; just walk with a normal gait pattern of opposite arm and leg swing. For example, left leg and right arm/pole swings forward to plant while the left arm/pole remain behind with the right leg .  

This pattern is reciprocated with as normal gait advances (opposite arm and leg). I have been very pleased with my moderately priced poles (Cascade Mountain Tech from Dick’s Sporting Goods ($34.99 per pole). Prices range from $19.99 to 79.95 per pole. dickssportinggoods.com; montem.com; leki.com; rei.com. However, if you travel frequently to hike the State and National Parks, you may want to purchase more expensive poles that collapse and retighten more efficiently. (montem.com; leki.com;)

Research:

There are numerous studies to support the use of trekking poles, especially research that supports their use for health and safety. One study compared hikers in 3 different conditions; no backpack, a pack with 15% body weight and a pack with 30% body weight. Biomechanical analysis was performed blindly on the three groups and a significant reduction in forces on lower extremity joints (hip, knee, and ankle) was noted for all three groups when using poles compared to those not using poles.

Another study confirmed that trekking poles reduced the incidence of ankle fractures through improved balance and stability. Additional studies support the theory that trekking poles reduce exercise induced muscle soreness from hiking or walking steep terrain and another study found that while less energy is expended in the lower body muscles using poles, increase energy is used in the upper body; therefore, the net caloric expenditure is equal as it is simply transferred from the legs to the arms.

Reasons to Use Trekking Poles:

• Reduced Stress on Lower Back, Hips, Knees, Ankles and Feet – Biomechanical studies confirm that using trekking poles creates less stress on the lower back and joints of the lower body. Those with a history of degenerative arthritis and pain in these areas are wise to consider this when planning to hike or walk distances for exercise.
• Improved Stability and Balance/Less Injury – Studies have found that those using trekking poles were less likely to suffer sprains, strains and even fractures of the lower body, especially the ankle, due in great part to the improved balance and stability. This benefit is found not only on uneven terrain, but also for those walking distances and may have age-related balance issues.
• Upper Body Workout – One comment I have heard from those questioning the value of trekking poles is that they do not want to make their walking/hiking exercise too easy because they desire a “good workout.” Studies show that the caloric expenditure is equal to exercise without using poles as the energy is simply transferred from the legs to the arms.
• Improve Walking Posture and Stride - It is common when walking distances, especially if carrying a backpack, to lean your trunk forward. Using poles has been found to promote a more upright posture while walking.
• Less Perception of Cardiovascular Exertion - While cardiovascular demands increased with pole walking, subjects reported less exertion when using poles. 
• Reduced Exercise Induced Muscle Soreness - Studies testing the blood for chemicals associated with muscle damage found less exercise induced muscle soreness/tissue damage and delayed onset muscle soreness among pole users. This was reported to be critical in walkers and hikers who participated in their activities several days in a row to complete the task such as hiking in and out of a canyon.

In conclusion, it is important to remember that trekking poles for hiking or distance walking are much more than a style statement. They are proven to be an invaluable tool for health, safety and wellness by reducing lower extremity joint stress, improving stability and balance, and enhancing efficiency for muscle recovery.

November is also Native American Heritage Month!

Happy Thanksgiving! Like most of you, I am most thankful for the love and support of my family and friends. I am also very thankful for health and wellness. But this year, the year of the global pandemic which has limited my access to the warm hugs and smiles of those I love, I am more grateful than ever for simple things…the beauty of nature and the great outdoors in NEPA!

With this in mind, I am also grateful to the first environmentalists in the Americas…Native Americans! Long before John Muir and the Sierra Club, Native Americans were stewards of the planet. Native Americans feel that everything in nature has a soul… living creatures, trees, mountains, rocks and even water! Therefore, they believe that all of nature must be treated with respect and honor.  Today, when being outdoors in nature is more important than ever, we are the beneficiaries of their stewardship. Now it is our turn to enjoy, respect and protect nature for future generations!

GET THE HECK OUTSIDE!

Research shows that spending time outdoors has many positive effects on your health. With a little imagination, one can find many year round activity options in Northeastern Pennsylvania. While swimming, boating, kayaking, biking and golfing may be winding down, consider other options this winter. With proper equipment and clothing, walking, running, hiking, fat-tire biking, snowshoeing, cross-country and downhill skiing can be enjoyed. Studies show that even less vigorous activities such as barbequing or reading a good book on the porch are healthier than being indoors... so bundle up next to a good fire pit or outdoor propane heater and get outdoors!

Even before the pandemic, it was reported that Americans spend 90% of their lives indoors and that number increases with age. Worse yet, for some, venturing outdoors is considered risky behavior with fear of the sun, heat, ticks, wind, cold, mosquitoes and other creatures of God. Well, the truth of the matter is the risk of being one with nature is far less than the ill effects of a life stuck indoors. Please consider the following benefits of spending time outdoors.

• Nature’s Vitamin D – Current research suggests that Vitamin D (The Sunshine Vitamin), may offer significant disease prevention and healing powers for osteoporosis, some forms of cancer and heart disease. Of all the methods of getting an adequate amount of Vitamin D, none is more fun than spending time outdoors in the sunlight. It seems that health concerns of ultraviolet light, sun burn and skin cancer have created an overreaction to the point of Vitamin D deficiency in many. Balance and common sense go a long way. One can attain normal levels of Vitamin D by being outdoors in the sun and exposing their arms and legs for 10 -15 minutes a few times per week. Additional time in the sun warrants sunscreen and Vitamin D supplements can be used if necessary.

• Increase Activity Level – While exercising indoors in a gym is valuable, research shows that time spent indoors is associated with being sedentary and being sedentary is associated with obesity, especially in children. Some studies show that children in the United States spend an average of 6 ½ hours per day with electronic devices such as computers, video games and television. It is also reported that a child’s activity level more than doubles when they are outdoors. So, get out of the office, house and gym as often as possible. Consider weight training at the gym and doing cardio by walking, biking or running outdoors.    

• Improved Mental Health – It is well documented that light affects mood. So, unless you live in a glass house or a light box, getting outdoors is important to your mental health. Furthermore, studies show that exercising outdoors in the presence of nature, even for as little as 5- 10 minutes has additional mental health benefits. For those less active, read or listen to music outdoors next to a fire.

• Improved Concentration – Richard Louv, author of the book, “Last Child in the Woods,” coined the term, nature-deficit disorder.” This term is supported by research that found children with ADHD focus better when outdoors. Furthermore, it was discovered that these children scored higher on concentration tests following a walk in the park than they did after a walk in their residential neighborhoods or downtown areas, showing the benefit of the “green outdoors.”

• Improved Health and Healing – Researchers at the University of Pittsburgh found that patients recovering from surgery recovered faster with less pain and shorter hospital stays when they were exposed to natural light. Next time you’re recovering from an illness, discuss this with your physician.
• Improved Breathing – In general, breathing fresh air is good for you. Some exceptions might be those with severe allergy problems when the pollen count is high. In spite of this, it may be better to take allergy medicine and enjoy the benefits of being outdoors than to be stuck inside. Many pulmonologists believe people with pulmonary problems would benefit from outdoor activities such as a 10-15 minute walk because they are prone to osteoporosis and Vitamin D deficiency.  Local pulmonologist, Dr. Gregory Cali, DO, agrees and also adds that studies do not show that high humidity is dangerous for respiratory patients but it may be uncomfortable. In cold temperatures, those with pulmonary problems must avoid directly breathing cold air by covering up their mouths when walking outdoors. Overall, the benefits far outweigh the risks.
