Средние и длинные дистанции<br />
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 />
versus time curve at
