Summer running obviously increases the core body temperature. On average a
runner will expend 500-1500 kcal/hr depending on the experience and fitness of
the runner. Body metabolism means that energy produced is 25% efficient. 75% of
energy is used for the production of heat; this can be difficult during summer
running.
We recommend you drink adequate fluid 30-45 minutes before running and then
a cupful every 10-15 minutes. Experts have recommended 6-8 oz every 20 minutes
while you run. Most popular sports drinks have a low level of electrolytes and
also carbohydrates to helps speed up glycogen replacement. After exercise you
should try and drink more water than necessary to speed up recovery.
Some runners prefer the taste of sports drinks in comparison to plain
water. Experts have also recommended the use of carbohydrate protein drinks or
milkshakes to rapidly replenish glycogen stores after a run. These drinks also
help to catabolize muscles for energy and help muscles repair quickly after a
run. The above advice can be used for all types of running conditions but is
especially important during summer running. This is due to the warmer
environment deplenishing glycogen stores more quickly. In most cases runners
suffer from heat stroke and heat exhaustion due to poor hydration.
Acclimatization
It is advisable to gradually build up your tolerance for running in warmer
conditions. To acclimatize to the heat you should spend 1-2 weeks running from
2-6 miles a day and then gradually building up your mileage in the heat. You may
wish to run in the morning or late evening when the humidity is at its lowest.
Alternatively if you are worried about your personal safety then a treadmill in
an air conditioned gym may be a safer option.
