How to protect yourself from Sudden Death - IMMDA advisory
Running in Marathons and half Marathons brings intrinsic risks, which sometimes result in Sudden death - always widely reported in the mass media. At a scientific meeting held in Barcelona on 20 March the International Marathon Medical Directors’ Association (IMMDA) considered how risks can at least partly be offset through understanding and respecting the distance.
Current theory behind Sudden Death in endurance running suggests that this very often arises from underlying conditions of which the runner was not previously aware. Exercise can increase the risk of cardiac incidents, including heart attack and death, but the risk is reduced by regular exercise (above all by exercise honed into a specific training programme). Striving to surpass the runner’s established level (as all competitors do, in a race) may bring various mechanisms into play that can have a seriously adverse effect.
These include:
i) the release of muscle enzymes which may activate platelets and produce a clot and a less oxygenated blood flow to the cardiac muscle
ii) risks associated with increased caffeine consumption (above 200mg) during endurance exercise.
iii) the dilution of sodium within the body (Hyponatremia). This is preventable if runners drink for thirst, take sports drinks and salt, and do not take non steroidal antiinflammatories while running.
iv) a significantly increased effort over the last mile; increased adrenaline levels could drive a susceptible cardiac muscle into an unhealthy rhythm or even a stoppage.
To reduce risks, IMMDA suggests that runners should:
1. Adjust their ambitions to their preparedness; they should not only be sufficiently trained, but also define a personal goal and a corresponding race plan that is appropriate for their level of training and fitness.
2. Undergo a yearly medical examination in which exercise, plans, goals are fully discussed.
3. Consume one 81mg aspirin on the morning of a long run or walk of 10km or more, if there is nomedical contra-indication.
4. Consume less than 200mg caffeine before and during a race of 10km or more.
5. Only drink a sports drink or its equivalent during a workout of 10km or more.
6. Drink only for thirst
7. Not take any non steroidal antiinflammatory during a run or walk of 10km or more.
8. Consume some salt (if no medical contra-indication) during a run or walk of 10km or more.
9. During the last mile, maintain pace and avoid sprinting the last part of the race.
