Hydration and performance in sports -
If water loss through sweat starts occurring at a higher rate than fluid intake, then dehydration will start to take over and affect both sweating and heat dissipation from working muscles.
Catching and treating dehydration early is key to staying in the game. Read up on identifying, testing for, and correcting dehydration in this article by GoHealth Urgent Care. Did you know that not staying properly hydrated can reduce exercise endurance nearly in half?
For instance, if your endurance time is minutes, dehydration can drop your endurance time down to 55 minutes. Some effects of dehydration include a reduction in blood volume, decreased skin blood flow, decreased sweat rate, increased core temperature, and an increased rate of muscle glycogen use.
Dehydration can not only impact your performance physically but it can also negatively impact your mental game. Your cognitive performance is just as important as your physical performance. Dehydration can lead to slower reaction times, increased fatigue, and poor concentration.
The climate plays a role in hydration levels as well. Shoutout to the intense Arizona heat for providing even more reasons to stay properly hydrated all year long.
Luckily, there are ways to ensure proper hydration before your activity, during your activity, and after your activity. Yes, all three times are equally important.
A quick way to calculate how much water you need in a day is to take half your weight in pounds and convert it to ounces per day. For example, if you weigh pounds, you would need 80 ounces of water.
One regular bottle of water is roughly 16 ounces, so you would need at least 5 bottles per day for proper hydration. Follow these tips to develop your hydration strategy based on your individual needs to stay ahead of your competition.
Hydration is something that can often be dismissed. Critical reasons are that it helps regulate our body temperature, keeps joints in minimal friction, delivers nutrients to cells, proper organ functions, stable sleeping cycles, maintains brain function, better performance prevents constipation, and many more direct and indirect benefits.
Staying adequately hydrated is the key to prevent injuries caused by muscle fatigue which in turn leads to increased chances for injury. Also, Learn about foods to speed up muscle recovery.
The average person should drink L water a day at a minimum, plus approx ml-1L fluids for every hour of exercise. Drinking excessive amounts of water without additional electrolytes, i. sodium can cause electrolyte imbalances and reduced concentrations in blood, called hyponatremia.
While there are no official guidelines for drinking water, it is recommended you drink from 2 to 3 litres of water drank little and often throughout the day, plus ml-1L per hour of exercise.
It is recommended that you drink to ml of water two hours before any form of exercise. During exercise, you lose plenty of fluid through sweat to regulate body heat. To replace fluid through sweat, we need to drink sufficient water.
During exercise, athletes will typically lose anywhere between 0. This can depend on training duration, but water is still the first point of call. Sweat contains electrolytes such as sodium and water, so simply drinking only water when sweat rates are high during prolonged training could be susceptible to hyponatremia, an imbalance between body water and sodium levels causing a diluted effect.
Electrolytes aid absorption across the intestine, retain body water in cells and are also involved in muscle and nerve function. Carbohydrates may also be required during high-volume training, but without adequate hydration, they will not be adequately absorbed.
It also contains a small number of carbohydrates that are sufficient to fuel your training and boost brain and muscle function without unwanted GI problems. During exercise or any physical activity, which can include daily chores like gardening or hoovering, our core body temperature will rise.
When this occurs, our body will automatically respond by trying to maintain a level of homeostasis by cooling itself down thermoregulation.
So, there is a great importance of water for athletes. By doing this, the body will start to sweat, allowing water to be evaporated from the skin and release heat. During prolonged periods of exercise, sweat rates can increase and lead to dehydration if fluids are not consumed to alleviate this deficit.
This will ultimately impair exercise performance and, in severe conditions, can be hazardous to health. Calculating your sweat rate is a practical and important technique for getting the most from your nutrition to maximise performance.
Weighing yourself before and after training and measuring how much you drink during that session is all you need to get a good estimate. Drinking 1. Otherwise, it will be passed out in the urine. But, when considering other nutritional requirements after training, your body may also need protein and carbohydrates.
Milk is a natural source of protein, carbohydrates, and sodium and is more effective for hydration, protein synthesis, and glycogen replenishment than commercialised sports drinks.
So if you have milk to hand, then this could be your best choice. Another factor to consider is the weather. Therefore, it would be prudent to include more fluids with added sodium during and after training.
Dehydration increases your chances of underperforming through various cardio strains and thermal strains of heat illness. So, how does dehydration affect sports performance? Turning up dehydrated puts added pressure on your body to supply muscles with nutrients and oxygen, meaning your heart needs to work much harder to meet that demand resulting in premature fatigue.
Colour, volume, and smell are good indicators of hydration status — dark colour, small amounts, and strong smells can all signal dehydration. Monitoring hydration status should be a key part of your training!
See the urine colour chart to manage your hydration practices. During exercise, you should attempt to replace some of the water lost through sweat, but this should never be done at the expense of gastrointestinal GI discomfort. See below. Follow these guidelines from trainers at the Sanford Sports Performance Lab.
Proper hydration starts before you hit the court, field or gym. Start off your training sessions or competitions with all the fluids you need to perform safely and at your best. The goal is to have regular urinations that are light yellow in color.
Adults should drink about 6 to 12 oz. of water or sports drink every 15 to 20 minutes. One mouthful of water is about one ounce. Sports drinks provide water, as well as electrolytes and carbohydrates.
Electrolytes help regulate the balance of fluids in your body, making them essential for hydration. Drinking a sports drink helps replenish the electrolytes you lost while sweating. Carbs serve as a fuel source to help you maintain activity without hitting a wall.

Water maintains pefrormance volume, regulates body temperature and is involved in muscle contractions 1. Consuming liquids replenishes the fluids lost during exercise. Restoring fluids maintains normal muscle function, helps prevent a decrease in physical performance and reduces the risk of heat stress 1. The symptoms of exertional heat stress are tachycardia, hypotension, hyperventilation, vomiting, diarrhea, seizures and coma 4.
