Because yHdration training sessions utilized in snd study consisted of already-scheduled team training sessions, athletes were recruited from in-season sports that were currently engaged in heavy sports-specific training sessions. Once recruited, participants underwent a qualitative assessment for hydration habits and knowledge.

Participants were interviewed one-on-one by researchers to gauge hydration habits and knowledge pertaining to dehydration and overhydration.

This subjective questionnaire consisted of a combination of open-response and multiple-choice questions. The full list of questions are shown in the results section of this study. Following this, participants were assessed for sweat loss, then randomized to either a prescription hydration plan PHP or asked to continue with their normal hydration habits NHP.

Maximum heart rate was estimated with the formula, 0. Heart rate HR was recorded remotely using the Zephyr PSM Training System Zephyr Technology Corporation, Annapolis, MD, US [ 18 ].

Mean and peak heart rate were recorded throughout the entire training session, including just prior to warm up, warm up, and min cool down. All measurements took place immediately before, during, or after a sports-specific training session. For example, hockey players recruited for this study underwent assessments during a full-pad, on ice, practice.

Similarly, Lacrosse players were assessed outdoors on the Lacrosse field during one of the teams harder practice sessions. The overall design of this study is shown in Fig. Each participant completed a training session with their NHP and PHP, separated by 7 days.

Randomized, cross-over study design to test the effectiveness of a prescription hydration plan on sports performance. To determine the NHP for each participant, researchers observed the hydration habits of each athlete during at least one training session in addition to reviewing the results of the hydration survey noted earlier.

No instruction was provided to athletes with regards to their NHP. Each participant was monitored during their NHP training session for compliance, particularly those who were randomized to follow a PHP first.

Researchers also controlled for pre-training hydration status by monitoring fluid consumption beginning at 60 min prior to the start of the sweat assessment, NHP, and PHP training sessions.

All fluids consumed during this study were kept at room temperature. Fluid loss from training was performed as described previously [ 9 ]. Briefly, nude weight was taken immediately prior to training. Fluid bottles 32 oz of water or sports drink of choice lemon-lime flavored Gatorade® were measured out and provided to each participant.

Participants were instructed to only drink from his or her bottle and consumption of fluid was closely monitored during the training session. Participants were again weighed immediately afterwards nude weight, surface sweat removed via towel dry.

The time of day, length of training session, temperature, and level of humidity during the session were also recorded. For reference, all sweat assessments took place during the cooler months November—March within the New England region of the U. Fluid loss was determined from the change in pre-training to post-training body mass and corrected for fluid intake.

Sweat rate was expressed in L. Relative sweat rate was expressed as ml. Activation of the sweat inducer served to deliver enough pilocarpine for sweat gland stimulation equivalent to 5 min of iontophoresis at 1.

Following induction, a macroduct sweat collector was placed over the skin where the red electrode was previously. The collector contained a blue dye that allowed the researchers to observe the collection of sweat by capillary action. Fluid losses for each athlete determined previously were expressed in ounces.

This time measurement was agreed upon by participants and coaches and represented a feasible fluid consumption plan during training sessions. For example, if an 82 kg athlete with an absolute sweat rate of 1. consumed every 15 min.

equivalent allowable sweat loss. at minimum that need to be made up via fluid consumption. of fluid consumed every 15 min at minimum. This participant would then be advised to consume between 2 oz. to 12 oz. of fluid every 15 min of activity. The bottles used in this study were individually marked for quantity to delineate how much should be consumed at each 15 min interval.

The exact volumes would vary from athlete to athlete and each participant would be instructed to sip their bottle at each interval such that the fluid line was between the minimum and maximum. For athletes engaging in training sessions that exceeded the fluid capacity of the bottle, multiple similarly marked bottles would be provided.

Researchers monitored fluid consumption throughout the training session to gauge whether an athlete was on track with their prescribed volume. This usually involved adding NaCl to 32 oz. of a commercially available sports drink or water depending upon which beverage-type was normally consumed by the individual.

For example, if an athlete lost Lastly, 30 min prior to engaging in a PHP training session, participants were instructed to consume 8 oz of their prescribed beverage.

All testing was conducted in a quiet, dimly lit room with minimal outside distractions and consisted of three 10 min trials interspersed with five minute rest periods.

During these assessments, participants wore 3D glasses and were required to track designated objects on a screen as they moved in variable patterns and at subsequently faster speeds.

Each of the assessments began at a preliminary speed of 1. The degree of difficulty associated with the assessment progressively increased with every correct answer provided by the participants.

In contrast, the level of difficulty associated with the assessment progressively decreased with every incorrect answer.

Each participant performed the neurotracker assessments before and immediately after the training sessions. Changes in spatial awareness and attention were illustrated by comparing pre-training with post-training scores.

To gauge lower body anaerobic power [ 25 ], three standing long jump tests SLJs were performed before and after the NHP or PHP training sessions. The pre-training SLJs immediately followed the neurotracker assessments, while the post-training SLJs preceded the neurotracker. Prior to completing the first of the three maximal SLJs, each participant completed two submaximal trials to become familiarized with the protocol.

For the test itself, participants were instructed to stand with their feet should-width apart behind a starting line. Wilcoxon Signed Rank test for paired samples was conducted in order to determine if there was a significant difference in the pre and post athletic performance measurements and when participants followed their normal hydration plans compared to when they followed their individualized prescription hydration plans.

All data are presented as means ± SD except where otherwise specified. SPSS 23 for Windows IBM SPSS, Chicago, IL was used for all statistical analyses. GraphPad Prism® software version 6. Fifteen NCAA Division I and II athletes from three different sports participated in this study.

Participant demographics are shown in Table 1. Relative and absolute sweat rates were 1. Seven of the 15 participants engaged in min training sessions, 6 engaged in 70 min sessions, and 2 engaged in 65 min and min training sessions respectively.

The duration and structure of the NHP and PHP training sessions did not differ for each participant. All participants had practice in the afternoon or evening. The time of day of the NHP and PHP sessions did not differ among any of the athletes in this study.

Hydration and Endurance Sports: water loss, electrolytes, and performance

Hydration and endurance training -

In general, new runners that are not used to intense exercise often experience lower rates of sweating, but higher rates of breathing during exercise than trained runners. Because these factors affect fluid and electrolyte balance in opposite directions, it is essential that runners calculate fluid losses after exercise to determine their exact needs.

Fluid-electrolyte imbalances can be associated with a variety of health conditions, but the two main issues facing runners are dehydration and overhydration. Dehydration is a condition of losing more fluid than is taken in.

It is common among endurance runners due to frequent, vigorous, and long bouts of exercise. In the early stages of dehydration, there are no major health risks. Mild dehydration can be identified by being able to recognize these common symptoms:. If dehydration progresses to moderate and severe stages, symptoms often escalate to nausea, confusion, and even lethargy.

At the point of severe dehydration, organ damage or even death could occur. It is vital that runners stay ahead of dehydration — not only to achieve optimal performance, but to prevent the development of serious health risks.

Overhydration, known as hyponatremia, is often caused by drinking too much water. The resulting fluid-electrolyte imbalance can cause headaches, confusion, nausea, and fatigue in mild cases or quickly progress to seizures, coma, or even death in severe cases.

Because endurance runners have higher fluid needs than the average person, this group is also at higher risk of experiencing hyponatremia through well-intentioned efforts to remain hydrated.

With this in mind, it is imperative that runners balance their water intake with sources of electrolytes as well. Keep reading to find out how this can be accomplished. Determining fluid and electrolyte needs as an endurance runner can be challenging because there are a variety of conflicting recommendations.

With this in mind, Tables 1, 2, and 3 provide the current evidence-based fluid and electrolyte recommendations for before, during, and after endurance exercise. It is recommended that you use these guidelines as a starting point to create a personalized hydration plan.

This will ultimately result in a hydration regimen that allows you to feel and perform your best. Two to four hours before exercise, runners should drink 0.

You should be comfortably full when you begin exercise. If you tend to be a heavy sweater or are exercising in a hot climate, your needs may be closer to 0. However, if you are going for a shorter run or do not sweat as much, you can drink closer to 0.

You can always adjust the amount you drink before your next run if you find that you need more or less. If you are doing a morning run and do not have time to hydrate 2 to 4 hours before exercise, drink at least 6 to 8 oz of water when you wake up. It is also important that you remain well-hydrated the day before your morning run.

Example: A lb individual should drink between Most pre-exercise hydration should come directly from water. If you would like to consume a sports drink with carbohydrates and electrolytes, do so within an hour of exercise.

If you are exercising for more than an hour, supplement with electrolytes. Products with both electrolytes and carbohydrates will be most advantageous to performance.

You can choose a sports drink, electrolyte powder, gels, or gummies. Salty foods such as pretzels and crackers can be a good option too. If you are a heavy sweater or are exercising in a hot climate, make sure your electrolyte source is rich in sodium.

Individuals in this category should consume roughly milligrams of sodium per hour during prolonged exercise. To assess fluid loss, weigh yourself before and after exercise. Any change in weight is reflective of a change in fluid status.

For every lb of weight lost, rehydrate with 16 to 24 oz of fluid. If you have gained weight, this is an indicator that you are overhydrating during exercise. Electrolyte replacement after exercise is dependent upon the amount of fluid lost during exercise. If you find that you have to replace a lot of fluid to maintain your pre-exercise weight, add an electrolyte beverage in alongside your water to avoid hyponatremia.

Your post-exercise meal can also contribute towards meeting your electrolyte needs. Because sodium is the main electrolyte lost through sweating, prioritize salty foods after exercise. These recommendations apply to all running durations — whether you are completing a short or long run.

However, if you are planning to run a shorter distance 3 miles or less and do not want to carry fluids during your run, just make sure that you hydrate before your run and replenish your fluid and electrolyte stores after your run by following the guidelines provided in Tables 1 and 3.

While the formal fluid and electrolyte guidelines provide runners with valuable technical information, it can still be difficult to implement and personalize these concepts in practice. Here are some strategies to assist you in achieving optimal hydration throughout endurance exercise:.

I agree. Close Open search. Close Nutrition Topics. Close Related Topics. Close Quick Links. October 16, Electrolytes and Endurance Performance Electrolytes are minerals that are often characterized by their ability to carry an electric charge when dissolved in water.

A loss of fluid equal to more than two percent means you risk nausea, vomiting, diarrhoea and other gastro-intestinal problems. When you need water , you need it. When you exercise, your body sweats as it tries to return to its optimal temperature.

As sweat evaporates from your skin, it removes heat from the body, but you also lose body fluid. You need to drink fluid during exercise to replace the fluids you lose when you sweat. It is possible to drink too much during exercise. Over-hydration, in rare but severe cases, can lead to death.

To avoid over or under-hydration, it can be useful to know your sweat rate. 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. 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 bodies , the 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 events , where 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.

Numerous studies have confirmed that performance traiinng be Memory enhancement methods when athletes decrease stomach fat dehydrated. Endurance athletes should drink beverages Interval training programs carbohydrate and endufance during and after training or competition. Drinking during competition is desirable compared with fluid ingestion after or before training or competition only. Athletes seldom replace fluids fully due to sweat loss. Proper hydration during training or competition will enhance performance, avoid ensuing thermal stress, maintain plasma volume, delay fatigue, and prevent injuries associated with dehydration and sweat loss.
