Hydration
During Running
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 a safer option.
Miscellaneous Tips
• Use sunscreen
to prevent sunburn to your skin.
• Replace running shoes every 300-400 miles.
• Do not break in new running shoes before you race or
before a long run.
• Make sure you wear you running socks when you are buying
running shoes.
• Try and wear synthetic fibre socks which will help to
evaporate moisture away from your skin and prevent blisters.
• Control excessive foot sweating during summer running.
• Wear light weight shorts and t-shirts to allow for evaporation
of moisture.
• Monitor any medical conditions you may have such as
high blood pressure. Certain conditions can increase by summer
running.
• DO NOT over estimate your
fitness, have realistic running targets.
