The swimming race is the most hectic part of the triathlon competition, as the competitors collide when vying for positions.
There are several possible reasons due to which the swimming part of triathlons is the most dangerous. For example, falling unconscious in deep waters can be fatal, even just a few seconds. In addition, plunge in cold water is one of the triggers recognized to sudden death.
The death is often due to fatal arrhythmias mediated by surges of adrenaline, such as immersion in cold water. It is believed that many deaths are secondary to a phenomenon called Pulmonary Edema Induced by Swimming, which is well known in swimmers and divers, and is caused by elevated pressures in the lungs as a direct result of body reflexes secondary to the cold water.
The exact mechanism is not fully understood, but is believed to be a combination of constriction of the blood vessels and accumulation of blood.
The dangers of running a triathlon
The triathlon is an event of ultra-endurance that test the limits of the tenacity of human. The overwhelming demands that will make up the body in the three disciplines are often the main attraction for the sport. Unfortunately, reported cases of sudden death in the triathlon have generated concern about the safety of this event.
despite this, there remains a lack of information on the prevalence and causes of deaths in triathlon. More importantly, there are unanswered questions about if and how the athletes should undergo a cardiac test prior to participation.
Factors associated with mortality in triathlons
Data from two large-scale registries, americans obtained reports post-mortem of medical examiners. In general there were 14 deaths during this period which corresponds to 1.5 per 100,000 participants. Most of the deaths occurred in men (80 percent) and runners of middle age (median age 44 years).
All the deaths occurred during the swim leg of the race, in addition to a death on a bike, that came as a result of injuries in the neck after a fall. Only nine of the 14 deaths had post-mortem data.
a Number of important findings were made. In the first place, the mortality rate does not seem to be related to the factors of race, the duration of the race, the type of place swimming and the start-up method of swimming (for example, mass, wave or time trial).
In the second place, the victims appear to have included athletes from a wide range of experiences in triathlon and the deaths were not limited to triathletes inexperienced. Among the main recommendations presented to the athletes was “to visit your doctor for a physical examination with emphasis on heart health before participating”
how to perform a screening of the athletes for triathlon?
The final question is whether triathletes should undergo a screening heart prior to participation. The detection is a novel concept in triathlons and marathons, which attract a large number of participants of different ages and experiences. however, in professional sports competitive, the screening is now a common place and even mandatory in some countries. It is supported by a number of agencies professional sports such as FIFA and the International Olympic Committee.
The most causes documented deaths in athletes are treatable and can be easily detected by simple tests, such as a path with heart (ekg) and an ultrasound of heart (echocardiogram).
athletes, including of course the athletes, are advised to visit your doctor for a physical examination with emphasis on heart health before participating.
The death is often due to fatal arrhythmias mediated by surges of adrenaline, such as immersion in cold water. It is believed that many deaths are secondary to a phenomenon called Pulmonary Edema, and most of these athletes are treatable and detectable.
That this will not desmotive to swim in open water. Though if there is the possibility of a strike, the percentage is low. Just keep in mind to visit your physician before you dispute demanding proof of this kind.
