An increasing number of people in the United States are hoping to complete a marathon.听Since 1990, the number of marathon finishers per year has more than doubled, and the number of marathons with over a thousand finishers has nearly quadrupled.1听Marathons attract听a large community of runners and athletes seeking out longer races and new recreational challenges as well as people hoping to get in shape. Non-traditional running events and half marathons have seen a significant increase in participation as well.2听Both full- and half-marathons require months of training that mandate perseverance, healthy eating, consistent training and a lot of motivation.听Health care professionals, for example a certified medical assistant, need to be prepared to aid patients that may have concerns听about tackling such a massive undertaking. People looking to run their first marathon will likely have questions about diet, injury and general health.
A marathon’s effect on the heart
The heart undergoes significant stress when training for a marathon听due to the intensive cardiovascular regimen needed to properly train, along with actually running the race itself. Regular exercise is considered essential to a healthy lifestyle, however, endurance exercise can overuse the heart muscle and increase the听risk of听arrhythmias, a condition that causes the heart to beat irregularly.3听Arrhythmia can mean the heart is beating too slow, too fast or erratically. Several studies suggest that听the heart can weaken due to too much exercise overall.4 Other evidence suggests endurance running puts participants at risk of myocardial damage.5听In addition,听running a marathon can put people with heart conditionsat risk of additional injury.6听A Swedish study conducted by the听Department of Cardiology at the Karolinska Institute听found that an extreme amount of exercise as well as a听notable lack of exercise raises the risk of atrial fibrillation.7听This study found that men who exercised regularly in moderation had a lower risk of atrial fibrillation than those that either neglected to exercise or exercise everyday. Doctors and other health care professionals can utilize this information to alert patients and help them understand the potential risks of running a full-length marathon.
Eating right for a marathon
Running a marathon necessitates a long-term change in diet to accommodate for听the overall changes in levels of endurance exercise and calorie consumption.听Many first-time marathon runners might not be prepared to alter their eating habits to fit their new workout plan. Health care professionals can assist in this process by recommending foods that not only听complement heavy exercise, but also听prepare runners for the physiological and psychological challenges of running for hours on end.听A good training diet is heavy in nutrients, carbohydrates and protein.听Daily calorie and nutrient consumption should be monitored and aligned with each day’s running schedule. Learning how to properly fuel up helps prevent muscle fatigue, which听in turn can听reduce risk of injury.8听A healthy marathon diet can further benefit runners by strengthening the immune system and restoring muscle tissue more efficiently.9 Each person has individual nutritional needs.As such,听discussing and tracking one’s听diet can be an effective way to help marathon runners perform their best. A great way to help patients with their marathon diet is to encourage听them to maintain a food log, giving them a detailed profile of their daily caloric intake.
Training safely and avoiding injury
Another question most first-time marathon runners will probably have regards the听risk of injury. Marathons are associated with chronic injuries such as听runner’s knee, patellofemoral pain syndrome, and iliotibial band friction syndrome.10听Other possible conditions include shin splints, plantar fasciitis and stress fractures. Helping protect runners from these type of injuries means, first and foremost, encouraging them to voice any pains they experience, as these听could potentially lead to more harmful, long term problems. Health care professionals should talk to patients interested in running marathons about the importance of properly resting听and icing sore muscles, stretching, and investing in proper footwear.11 Finding the right running shoes can limit risk of injury, so being able to recommend a local running store or specialist can assist patients. When runners try to push their bodies beyond what they are capable of, they are putting themselves听in jeopardy of sustaining a serious injury. For medical personnel, working with first-time marathon runners and endurance race veterans alike requires cooperation to form individual goals and workout plans. Seasoned runners are exposed to higher risk听of chronic injuries that can require continual attention. Helping any runner properly prepare and understand the limitations of their body will help听to avoid damaging听effects to the heart and various joints. Health care professionals should consider what a patient is capable of physically accomplishing and help them achieve those goals safely. 1“Annual Reports” Running USA.
