As lactic acid is produced by the breakdown of glycogen, pH decreases causing skeletal muscle fatigue 5. The athletes in a dehydrated state had an increased level of cortisol, which competes for certain enzymatic receptors in the body reducing the level of testosterone, the primary hormone required for muscle growth.

Additionally, increased cortisol concentration reduces the amount of testosterone released as a response to resistance-specific weight training 3.

Studies on water intake are limited in data compared to intake of other nutrients. There is no ideal amount of water that should be consumed. Despite the lacking data, the Institute of Medicine has declared an estimated ideal volume of water that people should consumed daily.

Male adults above the age of 18 should consume about 4 litres. Females above the age of 18 should drink about 3 litres of water. Water is involved in the majority of chemical reactions involved in athletic performance.

It is important that athletes are hydrated before, during and after physical activity to achieve their maximal physical performance. June Jeukendrup, Asker E. Sport Nutrition : An Introduction to Energy Production and Performance.

The Effects of Hydration on Athletic Performance Despite the commonly known importance of water in our bodies, many athletes do not seriously consider the effects of hydration during and after athletic performance.

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. However, if you are doing intensive exercises or training, you might want to consider taking sports drinks that contain carbs and electrolytes like sodium and potassium, which you lose while sweating.

Water is the best for all kinds of exercises, and it does well for any physical activity. However, energy drinks and sports drinks claim to improve energy levels, increase resistance and endurance, and improve performance.

Energy drinks may contain caffeine which helps to promote alertness for improved energy levels and sports performance during intensive training and competition. Caffeine has been shown to increase energy and fight muscle fatigue amongst adults. In conclusion, you might benefit from moderate consumption of either sports drinks or caffeinated drinks like coffee before training.

Staying hydrated is vital for athletes who undertake larger than normal volumes of training, and therefore must drink a lot more fluids to match that loss through sweat. Dehydration impairs performance and therefore must be avoided to maintain training intensity.

Normal people who go to the gym and exercise frequently also need to prioritize hydration. Athletes can measure their hydration status by analyzing their urine color and frequency of urination. Urine should be a clear, straw-like color to show good hydration levels, and going more frequently, whereas a darker yellow color, stronger smell, and going less often suggest dehydration.

Drinks that are classed as diuretics, mainly alcohol and caffeinated drinks over ~mg, may be linked to dehydration.

A urine color test is a very reliable and practical way of assessing hydration status. Monitoring sweat rates are a great way for athletes to determine the correct amount of fluid they need after exercise to rehydrate. Athletes will generally sweat more in hotter conditions and climates, therefore needing to drink more to rehydrate during and after training.

Having a sweat patch test done during training helps to accurately analyze your total sweat and sodium losses so you know how much and what type of drinks you need to consume to stay fully hydrated to maximize performance. Water is important for hydration but you can have too much of a good thing, meaning that drinking too much water can be detrimental to sports performance.

Drinking too much water can create an imbalance between the amount of water and sodium in your body, which can lead to Hyponatremia. Athletes will be okay only drinking water for shorter training sessions, typically 1 hour or less.

Dehydration causes: 1 Premature fatigue 2 increased heart rate 3 impaired thermoregulation 4 reduced concentration and cognitive function 5 greater reliance on muscle glycogen for energy 6 higher RPE 7 joint stiffness.

Sweat is made up of water but also contains vital electrolytes such as sodium, potassium, and chloride. Consuming drinks or supplements that contain these electrolytes helps to rehydrate better than water alone. Water is irreplaceable. Sports drinks can be beneficial if you use them to complement water instead of using them to substitute water.

The main ingredient of sports drinks is water, but the addition of electrolytes and carbohydrates make them a good energy drink during intense training sessions.

Drinking enough fluids to ensure your urine is a clear color and you are well hydrated before training is key. A good rule of thumb is to drink ml two hours before exercise. So long as you are well hydrated before you start training, you can drink to thirst for sessions less than 2 hours long.

On the other hand, some sports like cycling and triathlon that require strategic hydration strategies for their events will need to practice these during training to match their measured sweat rates.

Measuring the changes in your body weight during training will give you a good idea of how much to drink to rehydrate. Weighing yourself before and after training to calculate your weight loss e. This will be different for everyone based on their body weight and activity levels, but a good daily target is to consume 30ml per kg of body mass, plus an extra ml-1L per hour of exercise.

When playing sport it is important to stay well hydrated. Hydration is ensuring the body has sufficient water to do its basic everyday functions properly i. transport blood around the body. Sports drinks contain electrolytes like sodium which can help the body to better retain water when exercise lasts longer than 90 minutes.

Athletes should aim to drink approx 0. Being hydrated helps the body to cool down more effectively. It also lubricates joints, supports brain function and aids the transport of oxygen and nutrients to the working muscles, all of which are impaired in a dehydrated state.

Sweat rate is the amount or rate at which a person sweats. To calculate sweat rate, measure weight before and after a workout. The difference in the weight indicates how well the athlete is staying hydrated and whether it's within the healthy guidelines.

The weight difference plus any fluids consumed during workout equals the sweat rate. Understanding this number will guide the amount of fluid needed during the workouts or practices.

If young athletes are working out for one hour or less, water is generally sufficient to keep hydrated. Sports drinks may be recommended in certain situations including when:.

In these situations, experts recommend a sports drink containing at least to mg of sodium per 8oz. This will replace fluid and electrolytes lost through sweat.

Regulated blood pressure. Improved circulation. Staying hydrated also improves blood flow and circulation and thus the delivery of oxygen and nutrients to working muscles. Good hydration also helps remove metabolic by-products and waste from muscles, while replacing the water that is lost through sweat.
