Congratulations to more than 1,000 courageous runners who finished the 27th Annual Steamtown Marathon today. Most, if not all of you are waking up this morning with a little less jump in your step than you had yesterday.
As active people by nature, many of you will resist the logic of rest, despite the pain and stiffness in your muscles and joints. Therefore, I would like to offer some words of wisdom, based on science, to encourage you to adequately rest and allow your body to recover.
With adequate rest and recovery, an elite runner can quickly regain full form in 3-4 weeks, while an average runner may require 4-6 weeks. Meb Keflezighi, an elite American runner and winner of the 2014 Boston Marathon, is an excellent example of the merits of rest and recovery. However, he discovered it by accident…following the 2012 New York City Marathon, Meb developed a foot infection which required three weeks rest. With the Olympic Trials just 70 days away, Meb quickly regained his pre-injury fitness level to win the 2012 US Olympic Marathon Trials and join the US Olympic Team in London. It may be that his injury was fortuitous and allowed him adequate recovery time, (that he might not have otherwise allowed), preparing him for intensive training leading up to the trials.
The Effects of Running 26.2 Miles on the Body:
(RunNow.com - Jim Peskett)
One of the most obvious effects of running a marathon is significant muscle and joint pain and stiffness. It will set in after you sit for a while and attempt to get up and move around. For most, it will be more pronounced the day after the marathon, as you get out of bed and limp to the bathroom. Studies show that the leg muscles, (especially the calf muscles) display significant inflammation and necrosis (dead tissue) in the fibers of the muscle. In other words, the trauma to the muscles is so severe that tissue damage causes muscle cells to die. Consequently, studies found that muscle strength, power and endurance is compromised and required significant time to recover… sometimes as long as 4-6 weeks!
Additionally, many runners report severe bone and joint pain following the race. Some studies report findings of microfractures or bone bruising from the repeated and prolonged pounding of the marathon. It is purported that the stress on the joints may be related to: weight and body type, running shoes, running style and mechanics. While not dangerous, again, it is important to respect the stress placed on the body and allow adequate healing…LISTEN TO YOUR BODY!
Creatine kinase is an enzyme found in the brain, skeletal muscles and heart. It is found in elevated levels in the presence of cellular damage to these tissues, for example, following a heart attack. Similarly, significantly elevated creatine kinase levels are found in the blood of runners up to 4 days post marathon, demonstrating extensive tissue damage at the cellular level. It is important to note, that these enzyme markers are present, even if a runner does not experience muscle soreness. So, adequate rest for healing and recovery is required, regardless of soreness.
It is not a coincidence that the runners are more likely to contract colds and flu after intensive training or running 26.2 miles. The immune system is severely compromised after a marathon and without adequate recovery; a runner can become ill and ultimately lose more training time or will underperform.
FALSE: As stated above, enzyme levels that indicate cellular damage to the tissues are present in the post-marathon runner, even in those without significant pain.
FALSE: In addition to rest, drink, drink, drink - 24 ounces of water for every 2 pounds you lose after the marathon. This is based on pre and post exercise weight. You just burned 2,600 calories so avoid diet soft drinks. You need the glucose (sugar) boost. Also, don’t drink alcohol and use minimal amounts of caffeine (the equivalent of 1-2 cups of coffee). First, drink plenty of water and sports drinks (Gatorade) to prevent a diuretic like caffeine from messing up your fluid balance.
FALSE: Studies clearly show that the VO2 Max, (the best measurement of a runner’s endurance and fitness), is unchanged after one week of inactivity. And, after two weeks, the loss is less than 6% and can be regained quickly. Moreover, it is important to remember, without adequate rest and recovery, performance is comprised, not by the loss of VO2 Max, but by muscle-skeletal tissue damage, which renders the leg muscles of the runner weaker. Remember Meb Keflezighi!

Fall is here, cross-country running season has begun and the 26th 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.
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
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.
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.
