author’s opinion that one should not specifically<br />

train for 15oo metres. The training should rather be<br />

directed towards 800 metres, where if the blend is<br />

correct a fast 800 metres and a fast 1500 metres<br />

will be experienced. The rule that athletes should<br />

train at times faster than racing pace applies to 5k<br />

and 10k, and probably for marathon runners, too.<br />

Heat and cold<br />

Sports Medicine, 37, (2007), 4/5, pp. 400-403<br />

The medical work load seems to increase both with<br />

heat and humidity, and with cold and rainy conditions.<br />

Heat tolerance during exercise is variable and<br />

heat intolerance may contribute to collapse and<br />

increase medical encounters. Exposure to cold, wet<br />

conditions results in increasing incidence of<br />

hypothermia in exhausted marathon runners. Finishline<br />

encounters and course dropouts increase<br />

as conditions cool and warm away from the most<br />

advantageous conditions in the 4.4-15°(2 (40-59°F)<br />

wet bulb globe temperature (WBGT) range. The risk<br />

of requiring medical attention and not finishing rises<br />

considerably when the WBGT is > 15.5°(2 (60°F).<br />

Comparing the correlation coefficients of the Boston<br />

Marathon and Twin Cities Marathon data suggests<br />

that the risks of medical problems and not finishing<br />

are associated with the warmest temperature of the<br />

race and not the start temperature. The community<br />

consequences of races conducted in hot and<br />

humid conditions can be significant, particularly<br />

when the WBGT is >15.5°C. The emergency medical<br />

systems can be overwhelmed with a surge of<br />

patients, some very ill, and the emergency call<br />

response times drop to unacceptable levels blocking<br />

access for the citizens of the community. With<br />

respect to marathon encounters, heat stress<br />

increases both the finish-line medical encounter rate<br />

and the on course drop-out rate, and seems to<br />

increase the incidence of hyponatraemia and heat<br />

stroke. Cold conditions increase the drop-out rate<br />

along the course and, if associated with wet conditions,<br />

also increase the encounter rate.<br />

Exertional heat stroke in the marathon<br />

Sports Medicine, 37, (2007), 4/5, pp. 440-443<br />

Exertional heat stroke (EHS) during or following a<br />

marathon race can be fatal if not promptly recognised<br />

and treated. EHS is a true medical emergency<br />

and immediate cooling markedly improves the outcomes.<br />

It is critical to recognise EHS and stop the<br />

cell damage before the cascade of heat-induced tissue<br />

changes becomes irreversible. The goal is to<br />

keep the area that is >40.5°C under the body temperature<br />
