Last week, this column discussed the many benefits of snowshoeing as an option for those in NEPA to get outdoors and enjoy the winter. Today’s column will present another option for outdoor exercise when the weather is inclement…winter walking or running.

We live in such a beautiful environment. Each season brings its own unique beauty and winter is no different. Most will not have to abandon outdoor activities, but you must make some adjustments in equipment, clothing and food for each season and temperature changes that go with it. These tips are also appropriate for those who qualified for the Boston Marathon in the spring and will be training all winter, as well as those who enjoy walking and running throughout the winter for exercise. Consider the importance of making changes and adjustments in training as well as clothing and equipment, according to the weather and temperature.

SHOES AND EQUIPMENT for WINTER:

There are running shoes specifically designed for use in wet, cold and sloppy winter conditions. These running shoes, which can also be used for walking, are considered “winterized” because they offer waterproofing, sealed seams, gaiter collars to keep out snow and slop, slip resistant fabric, anti-roll stability features, anti-microbial material and aggressive tread patterns for traction on slippery surfaces. Some shoe recommendations for both walkers and runners include:

• Salomon – SpeedCross or SpikeCross - $ 200.
• Topo MTN Racer 3 - $150.
• Brooks – Ghost 16 GTX - $170

Additionally, I am a strong proponent of walking with trekking poles for improved balance and safety when brisk walking in winter conditions. They are light weight, adjustable, and collapsible. Some examples are:  Trekology Trek Z 2.0 – 45. and REI Co-op Trailmade $79.00. Also, an old pair of ski poles will work just fine.

Winter CLOTHING AND TRAINING:

Over the past several years great strides have been made on understanding the effects of extreme temperatures on performance. Current wisdom from the University of Otago in New Zealand has found:

• WARM-UP - Spend more time warming up followed by slow gentle stretching in cold temps.
• THE BRAIN - Can anticipate changes in body temperature, with feedback from the skin, and will adjust the intensity automatically. Subconsciously, the brain calculates the outside temperature and the duration of the activity and will automatically slow down the performance even before fatigue occurs. If the performer attempts to override the brain, the cerebrum responds by creating severe symptoms and sensations of exhaustion such as those associated with heat strain or hypothermia. Therefore, the temperature in which you intensely perform will overpower even the fittest athletes.
• STRATEGIES FOR OPTMIMAL PERFORMANCE IN COLD TEMPERATURE -
• Researchers developed various strategies for athletes to stabilize their core temperatures in extreme hot or extreme cold conditions.
  • BELOW 45 DEGREES FAHRENHEIT – CAUTION/COLD: Humans possess limited physiological defenses against the cold.
    • Clothing – it is important to layer clothing. Use performance apparel such as UnderArmor (headgear, gloves, shirts and pants) to allow sweat to breath away from the skin to the next layer of clothing. Use a facemask to cover your mouth and nose to prevent frost bite and warm air before it enters the lungs. Chemical hand and toe warmers are great. Wear running shoes designed for winter conditions when surfaces are slippery.
      • Warm-Up – gently warm up inside but don’t break a sweat. Wait for your running partner in the warm car or house until they arrive. The best warm up in very cold weather is to begin your activity SLOWLY! Runner’s, for example, should run a ¼ the normal pace for 3-5 minutes, then ½ pace for 3-5 minutes, then ¾ pace for 3-5 minutes to prevent injuries. After 10 to 15 minutes, you may open up the throttle.
      • Safety – is important. Be alert for icy patches and poor visibility for cars. Wear fluorescent and reflective colors running in fog, dusk or dawn. Run in daylight with the warmth of the sun when possible.
      • Cross-Train- if it is very snowy, skip the run and try cross-country skiing or snowshoe walking or jogging for a change. It is a great running substitute and vigorous workout!
      • Food & Drink – is different for activities in the cold. For short-term exposure (1-4 hours) make sure you fill your muscles with lots of glycogen by getting 4 grams of carbohydrates for every pound of body weight. During exercise consume extra carbs by drinking 5 to 6 ounces of sports drink every 15-20 minutes. Hikers and campers performing vigorous activity in the cold for days at a time will require extra fat in their diet and on their bodies to store for energy. This is no time to count calories or fat intake, as anyone who has climbed the high peak knows!
  • 45 TO 50 DEGREES FAHRENHEIT – OPTIMAL Many physiologists and outdoor enthusiasts consider this temperature range to be optimal. It still requires 10 minutes of slow warm-up by ½ to ¾ pace running or cycling. Also, layers are advisable to start off warm, keep warm and shed before you become overheated. Food and drink requirements are still important as with all long duration activities but may be ¼ to ½ the above requirements.

Part I of II

When I was a young boy growing up in NEPA, one of my favorite winter things was to walk in the freshly fallen snow. I loved the feel of fresh crisp air through my lungs, the mesmerizing sparkle of snow falling in the moonlight, the peaceful sound of silence as pedestrian and motor traffic came to a halt and only thing audible was the muffled sound of my boots as they crunched the snow beneath… for me, if it is sizzling hot in hell, it snows in heaven! Well, I am happy to share with you, as I struggle to hold on tightly to my “inner child,” I am as excited and inspired by a walk in the snow today, as I was 45 years ago. It is my hope, that this column will inspire my readers to consider a beautiful walk in the snow to rediscover their “inner child.”  

While there are many options and opportunities available to enjoy winter in NEPA such as downhill skiing, cross country skiing, winter mountain biking, ice skating, and sled riding, none is as easy and natural as snowshoeing.

The advantages are many:

• There is NO learning curve - if you can walk, you can shoe
• There is little to no risk of injury - it requires more endurance than coordination
• The equipment is inexpensive - as compared to skis
• The walking and hiking trails are free - Lackawanna State Park, Rails to Trails or the snow covered streets of your neighborhood
• The aerobic exercise is great and caloric expenditure tremendous. According to Weightwatchers, a person weighing 150 pounds will burn approximately 650 to 700 calories per hour of snowshoeing

As a result, the popularity of snowshoeing is growing rapidly. According to the Outdoor Industry Association, the number of snowshoe participants have increased by 7.5% to 4.1 million in 2011 and 40.7% overall since 2008.  

History (Raquettes GV, Quebec, Canada  info@gvsnowshoes.com)

While the advent of the wheel is estimated to have been approximately 3,500 BC, the snowshoe had already been established and developed by 6,000 BC according to Stone Age engravings found in Norway. The snowshoe was an instrumental tool used by early humans to cross the Bering Strait into North America.

Some historians feel the snowshoe developed, like many great inventions, as an imitation of nature. For example, animals such as the snowshoe hare use expansive feet to increase their surface area, limit sinking and move more efficiently through the deep snow. Hardwood frames with leather webbed lacing comprised the early snowshoes used by fur trappers, traders, and Native Americans. More recently, materials have advanced and light but durable aluminum frames comprise snowshoes that are used by park rangers and winter recreation enthusiasts.    

Equipment - Choosing the right snowshoe

3 Types:

1. Recreational Hiking Snowshoes - Recreation shoes are a good choice for beginners to be used on easy terrain, paths and    trails.
2. Aerobic/Fitness Snowshoes - Aerobic shoes offer a sleeker and lighter design for those interested in running or cross-training.
3. Hiking/Backpacking Snowshoes - Hiking shoes offer a strong and durable frame, slightly wider base of support and strong flexible bindings for difficult terrain.

Cost of Snowshoeing:

Like all sporting equipment, you usually get what you pay for. Snowshoes range in cost from $50.00 to $300.00. Most people will be fine in a good pair for under $100.00. LL Bean and Dick’s Sporting Goods and Sierra Store offer several affordable options.

Some equipment examples are Tubbs Wayfinder Flat - $199 and Redfeather  - $82.00. Ski poles are recommended for efficiency when snowshoeing. Traditional ski poles or adjustable hiking poles can be used. Warm and supportive winter boots or hiking shoes are essential.

Now you are ready to go! The next time a snow storm dumps 8 – 10 inches on NEPA, get outside BEFORE the streets are plowed. Put on you warm winter boots, strap them into the bindings of your new snowshoes and walk out your front door and explore your neighborhood as you have never seen it before...white, clean, glistening, crisp and quiet. Let your mind wander, enjoy winter and rediscover your inner child!

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.
