Taking part in a marathon is not easy and definitely not suitable for everyone because one needs to run for a distance of about 42 km. In October 2007, a 35-year-old police officer running in the Chicago Marathon collapsed and died. In Singapore, a 25-year-old army captain also died after finishing a half marathon in August 2007.
Does this mean that marathon is a dangerous sport? Before drawing any conclusion, let us hear what the experts have said about marathon.
In fact, statistics showed that sudden death during running a marathon is very rare. In Singapore, there is only one death in every 15,000 to 18,000 healthy runners each year. The more common one are ailments such as musculoskeletal and heat injuries, according to experts.
People with uncontrolled hypertension and ischemic heart disease should not take part in marathons. This is because unforeseen stresses from heat, dehydration and physical or psychological pressures could well strain the cardiovascular system. People suspected of other medical conditions should get a pre-race screen.
Once results of screening confirm one’s fitness for running marathon, he or she should then undergo adequate training. The runner should at least have completed a distance run of 30 to 32 km at some point during the training for a marathon. The purpose is to allow acclimatization to weather, testing the type of clothing need, knowing energy and fluid needs, and gauging body's limits.
Running for 42 km straight is very likely to wear out the body. The human body begins to experience fatigue as soon as the carbohydrate stores are depleted. Therefore, a high-carbohydrate meal should be taken before the big race to provided sufficient fluid and energy for a run. Meanwhile, do not try new food just before a race as this could cause gastrointestinal discomfort. Instead, opt for safe food choices such as bananas or power bars.
During the run, the runner should monitor his or her physical state because the day's temperature and humidity could also affect the body adversely. Under the hot weather, blood is diverted to the skin for heat dissipation. This, coupled with fluid loss from sweating, will affect the body's ability to deliver oxygen and energy to the muscles. Such disturbance of the body’s heat regulation would trigger the occurrence of heat stroke. The result could be fatal if multiple organ complications emerge.
Hence, the runner should be aware of such as high internal temperatures and significant changes in one's mental state. In addition, unusual chest pains or palpitations, disorientation or confusion could also indicate cardiac-related conditions and other injuries.
If runners could observe points mentioned above, they might minimize their risk of having fatal consequence during the marathon event.
