Hydration – The Other Equestrian Athlete
Fluids, not the sexiest of topics, but you know what is definitely not sexy? Dehydration. This week, as part of my series on nutrition and ‘The other equestrian athlete’ I want to talk about an often underrated topic – Hydration.
Due to the format of equestrian sports food and nutrition plays a lesser role than it does in sports such as triathalon or marathon, however hydration is of vital importance. If athletes who are getting around in the middle of the day in black leather boots, coats and helmets are not sweating large amounts, placing themselves at risk of dehydration, then I don’t know who is.
At it’s mildest dehydration is annoying. However, at its worst, it can be fatal. It is fairly well accepted that dehydration can impact upon athletic performance. Even a loss as small as 1% of body weight can lead to impaired performance. For someone my size (~70kg or 154 pounds) that’s a loss of just 700ml!
How does dehydration affect our body?
- Decreased ability to control the temperature of your body. Remember that we sweat primarily to help ourselves cool off, if we have lost fluid, we decrease our ability to cool off.
- Fatigue (tiring quickly)
- Feeling as though exercise is harder than it actually is
- Impaired cognitive function (thinking less clearly or the feeling of thinking slowly)
- Impaired nervous system function (dizziness, light headedbess)
- Increased heart rate
- Increased gastrointestinal distress (eg. nausea, vomiting and diarrhoea)
I was rudely reminded of the uncomfortable side effects of dehydration at my last dressage competition where Nonie and I debuted at medium. As if moving up a level wasn’t enough to deal with! I ended up with a nasty headache (which could only be fixed by codine) and very fatigued.
One of the problems with dehydration is that it also decreases the amount of fluid that the digestive system absorbs which means that once you are dehydrated it can be difficult to correct. As they say, prevention is better than a cure!
So what can we do to ensure we optimal hydration?
As a starting point to prevent dehydration you can aim to:
- Drink ~500ml of water with your breakfast
- Drink an extra cup of fluid for every hour of exercise
- Replace 125-150% of your fluid losses in the six hours following exercise. This information sheet produced by the Sports Dietitian’s Australia, explains how you can actually figure out how much sweat you loose during exercise
- Avoid excessive amounts of caffeinated drinks during the day
- DON’T rely on your thirst as a reminder to drink adequate amounts of fluid. The colour of your urine is one indicator of your hydration status.
What about sports drinks?
In general water offers a cheap and easy way to replace fluid losses, particularly in sports which are low in intensity and duration (ie riding)However if the weather is particularly hot, or you are working a number of horses across the day or riding for longer periods of time, sports drinks such as Gatorade or Powerade (which contain salt and other electrolytes which are lost in sweat) can be beneficial for replacing fluid losses. Sports drinks are best consumed whilst you are actually exercising.
