Hydration during night-time endurance events -
That way, you can work out exactly how much you should be drinking. You can , talk to your GP or an accredited sports dietitian External Link for a fluids plan.
Remember, this is your sweat rate when exercising at a particular ambient temperature. Your sweat rate will change with the temperature, so it can be useful to measure your sweat rate at different times of the year.
Water is the best drink to satisfy thirst and replace fluid lost during exercise. Drink water before you start exercising, too. Water boasts a huge list of benefits. Some athletes use sports drinks that contain electrolytes and carbohydrates, which have concentrations that allow the body to refuel during exercise.
Sports drinks may be useful if your activity is moderate to vigorous in intensity for more than 60 minutes see the Australian Dietary Guidelines External Link. However, sports drinks can be high in sugar, so consume them only if necessary.
Remember that fruit and vegetables contain a high proportion of water, so a fruit snack such as oranges can help your fluid replacement. To adequately rehydrate after your exercise session, aim to drink one and a half times the fluid you lost while exercising.
Spread it over the next two to six hours. You need to drink more fluid than you lost while exercising because you continue to lose fluid through sweating and urination for some time after you have finished your session.

But taken endurnce the extreme as Body cleanse detox often isendurancd Performance enhancement software reminds me of the famous Henry L. it is more dilute so whenever you produce sweat you lose proportionally more water than sodium.
As a result, your blood becomes saltier rather than more dilute as you start to dehydrate. Those rising blood sodium concentrations are a key part of what drives you to become thirsty. So if you drink water only in response to thirst, you should only ever dilute the blood back down to an acceptable level before the cycle repeats itself.
You should never end up badly diluted hyponatremic unless you drink ahead of thirst which would dilute your blood sodium more than necessary or go for hours and hours drinking only water without replacing any salt. But in general, the idea of drinking solely to thirst seems an acceptable defense against hyponatremia in most cases.
There is, I believe, a huge difference. The environment that we now enjoy in much of the developed world—specifically in terms of our free and ready access to water and salt—is also very different from that of our ancestors.
And even if you are perfectly aware of your thirst signals as a general rule, the elite athletes we work with are very in touch with their bodiesthe demanding and complex nature of competition can make it difficult to find physically and tactically ideal moments to hydrate.
Drinking water to thirst is very likely sufficient for short and light activities where sweat losses are low to moderate, but the data is a lot less clear for longer and hotter eventswhere sweat loss can be considerable over many hours.
It was even copied by many of his competitors, presumably because it worked. More recent research showed that triathletes who were given salt tablets vs. a placebo during a middle distance race were ~26 min faster on average. The study also showed that the group taking salts rehydrated more effectively than the control group.
This certainly tallies with my own experiences using sodium supplements during long, hot races. Sports drinks are arguably overused by a lot of people, but they have been proven time and time again to provide performance-enhancing benefits to athletes and humans in general in the right scenarios.
There are lots of scenarios where just drinking water to thirst is sensible, like for basic day-to-day hydration. And for many people training or racing shorter events in cool to moderate conditions, drinking water to thirst will be sufficient most of the time.
There may be some benefit to having a basic hydration plan to follow, or in taking steps to ensure you start properly hydrated.
Your plan should be individualized and flexible enough to be tweaked on the go. It should also utilize biofeedback including a big reliance on your sense of thirst to determine how much fluid and sodium you take in. Taking this free online Sweat Test can help you get started.

What do you eat the night before a race?Hydration during night-time endurance events -
btn, a. Triathlons are among the most grueling endurance events, demanding peak physical and mental performance from athletes. Given the challenging nature of these competitions, athletes are constantly seeking ways to enhance their performance.
One aspect that could be useful in targeting is the risk of dehydration and fatigue. One strategy that has gained attention is hyperhydration, or intentionally over-hydrating before an event. The concept behind hyperhydration is grounded in the belief that having a surplus of fluids can provide advantages in endurance performance, thermoregulation, and overall physiological well-being during the event.
It is a valuable strategy when fluid losses cannot be compensated by fluid intake during exercise. It is important to note that water alone is not helpful in hyperhydrating.
The use of sodium or glycerol has been investigated to improve total body water in athletes because of their osmotic capacity to induce water storage.
Dehydration concerns many athletes, especially during endurance events where fluid loss through sweat can be substantial. Hyperhydration is a preemptive measure to counteract fluid losses during the event, potentially reducing the risk of dehydration-related performance declines.
Adequate hydration helps regulate body temperature, a critical factor in endurance sports. Dehydration can result in vasoconstriction of blood to the skin to assist your cardiac function. In doing so, one of your main mechanisms of cooling is reduced.
Hyperhydration could offset this by ensuring enough blood volume in your system to keep the heart working efficiently and reduce vasoconstriction. It has also been hypothesized that hyperhydration assists with central cooling.
Every one-percent body weight loss results in an increase of core temperature by ~0. This is one mechanism of how heat stress impacts the body and performance. Some studies suggest maintaining optimal hydration levels can positively influence endurance performance.
This is related to the negative influence that reduced blood volume from dehydration can have on cardiac output. Less blood volume results in less cardiac output. This is another mechanism of how stress impacts the body. Proper hydration is vital for physical performance. It is also crucial for mental clarity and focus.
Dehydration can lead to reduced focus and decreased accuracy in attention. Being dehydrated by just t wo percent has been found to impair performance in tasks requiring attention, psychomotor, and immediate memory skills, all of which are required to stay focused and safe during a workout or race.
Hydrated athletes can experience enhanced confidence and a more positive mindset, contributing to overall race-day success. Hydration status can impact fatigue levels, as even mild dehydration can decrease energy and physical capacity.
Hyperhydration may stave off early-onset fatigue during the event. Athletes might hyperhydrate to minimize the need for fluid intake during the event. This can be particularly useful when access to fluids might be limited, or if athletes are concerned large amounts of fluid in-race will cause gastrointestinal distress.
Glycerol and sodium are often used with hyperhydration strategies to enhance fluid retention and maintain electrolyte balance. Glycerol is a sugar alcohol used as an osmotic agent. You can purchase Glycerol from food manufacturing suppliers as it is a thickener and sweetener food additive.
Glycerol can attract and hold water, effectively increasing the total body water. The mechanism by which glycerol assists in hyperhydration is through its osmotic effect. As it does so, it draws water with it due to its osmotic properties. Previously it was banned by WADA in for its role as a plasma volume expander.
In , this was overturned and is now an approved supplement with evidence to support its use in appropriate environmental conditions. Sodium is an essential electrolyte crucial in maintaining fluid balance within the body.
Sodium assists hyperhydration by influencing fluid retention. Sodium affects kidney function by promoting water reabsorption and reducing urine output via the stimulation of antidiuretic hormone ADH. In this sense, sodium ingestion with fluids effectively retains consumed fluids, and is potentially more effective than glycerol.
For more on this, check out How Much Salt Do You Need While Training and Racing? Published in Sports Medicine , the aforementioned systematic review included 38 studies and participants investigating the impact of pre-exercise hyperhydration on exercise performance, physiological outcomes, and gastrointestinal symptoms in triathletes.
Only one study included exclusively female participants. Because of these limitations, it is essential to consider all findings with an open mind and accept that this is not a black-and-white topic. The increased plasma volume resulted from the increased hydration status.
The improved cardiac function outlined likely contributed to the positive findings related to TTE. Seven studies investigated the impact of hyperhydration on TTE. Five of these studies did report a significant increase in TTE after both glycerol and sodium loading.
Hyperhydration may improve endurance performance, although results are conflicting and equivocal. One study that simulated a triathlon found a 5. The running studies found no difference in TT performance when comparing glycerol or sodium to placebo. The cycling studies included in the review had varying results with no significant improvement in TT performance.
However, most of the studies had limited duration minutes , somewhat defeating the purpose of hyperhydration. One thing to keep in mind: Medications and some foods can change the color of urine, so if you are on antimalarials, antibiotics, or a number of other medications, these simple color rules may not apply.
Yes, athletes do need to consume more than the recommended amount on training days. They can start with the to ounce recommendation and add fluids according to how long they are training. One way to see how much additional fluid you need is by determining your sweat rate. To do that, weigh yourself before and after a one-hour workout, and drink 16 to 20 ounces of fluids per pound that you lost.
If it is dark yellow, you need to drink! A general rule of thumb is to drink about four to five ounces every 15 minutes of exercise , but again, that varies depending on the individual, and the type and intensity of exercise, says Milton.
Dehydration may also contribute to painful muscle cramping , which can impact athletic performance. If an athlete drinks an excessive amounts of water without replacing electrolytes, they can cause a dilution of electrolytes in the body, which can lead to a dangerous condition called hyponatremia low sodium levels in the blood , Kissane explains.
Another option is to consume something salty, such as pretzels, before the workout and have it with fluids. Overhydration can lead to exercise-associated hyponatremia, which means you have too much water and not enough sodium in your blood.
Symptoms of hyponatremia include nausea and vomiting, headache , confusion, and muscle weakness or cramps. If hyponatremia becomes severe, there is risk for seizures, coma, and even death. A recent study published in Wilderness and Environmental Medicine found that to help avoid hyponatremia, you should consume sodium or salty snacks along with fluids, and drink to thirst—being careful not to drink too much.
The best thing to do is have a sports drink with electrolytes and avoid very high sodium supplements. You can also tell by the frequency of urination. Another way is to check your skin. If you pinch your arm and the skin snaps back quickly, it is a sign of better hydration, Milton adds.
