Basically, exercise will cause muscle fatigue which will, in turn, increase excitatory afferent activity and decrease inhibitory afferent activity.

This leads to altered neuromuscular control which then affects alpha motor neuron activity leading to EAMC. Although, it is important to recognise the number of factors that will determine the severity e.

exercise intensity, duration, conditioning level Hyponatraemia is caused when an individual consumes fluids low in sodium or sodium-free water and does not replace the necessary electrolytes lost As a result, marathon runners seem to be prone to hyponatraemia when they do not implement effective hydration strategies There also seems to be a relationship between the severity of the symptoms e.

nausea, headache, confusion and fatigue and the amount by which blood sodium concentration have fallen Dehydration and Death As previously touched upon, there can be serious health risks for individuals who exercise whilst dehydrated. In some extreme cases, there have even been several reports of death due to heat stroke, with dehydration said to be a contributing factor To prevent this from occurring, there are natural neurophysiological processes in place to maintain homeostasis.

Thermoregulation is the process in which heat is dissipated from the body in order to maintain an optimal core temperature 37 °C It is proposed that dehydration reduces cardiovascular function, which, therefore leads to a decrease in skin blood flow and the inability to lose heat via sweat 8, 21, To summarise, given the impact hydration can have not only on performance but also on health, this firmly demonstrates the importance of having some form of hydration strategy in place to ensure athletes are well-informed and monitored.

Urine Specific Gravity USG Urine Specific Gravity USG is the density of a urine sample compared to the density of water 6. The density of the sample is determined by its osmolality, as well as the concentration of a number of molecules such as urea, protein and glucose.

Bioelectrical Impedance Analysis BIA Bioelectrical Impedance Analysis testing can take the form of many types, these include:. This article will mainly focus on SF-BIA because it is of relatively low cost, portability and practicality Whilst it has been criticised for its poor accuracy in subjects that have significantly altered hydration levels e.

in clinical settings , it can still be used to estimate total body water TBW in subjects that are normally hydrated; such as athletes The science behind this approach is quite simple: it involves an alternating current passing through the body 50 kHz and the resistance to the current is measured 6.

There are a number of ways that this can done, such as using gel electrodes that are placed on both wrists and ankles or using a stand-on platform with hand-held devices 6.

This method is seen to be safe, rapid and easy to administer, however, the machine used to calculate the estimations can be quite costly. The positive side of that is that there is minimal technical skill required to work the machine.

The accuracy and precision of results can be affected by a number of factors 25 such as:. Body Weight Changes Body weight changes have been used in the past to measure acute changes in hydration status It is assumed that 1 ml of sweat represents 1 g of mass lost 2.

The mass loss can then be used to express the post-training BW as a percentage of pre-training BW through the following equation:. For example, if an athlete weighed in at 78 kg before training and weighed out at However, it is important to note that there are many factors that could limit the reliability and validity of the results.

Using this method assumes that all mass lost during exercise is only due to sweat, but many other factors can contribute towards mass loss Some of these include:.

However, it is important to understand the different variables that can affect the reliability of the results. Urinary Indices Hydration status can be measured by monitoring characteristics such as volume, colour conductance and osmolality 6. Under normal conditions, the amount of urinary volume excreted can range from 1.

When exercise commences, water conservation mechanisms are activated in the kidneys to ensure that both plasma volume and intracellular water are maintained, this has an effect on the aforementioned urinary characteristics.

how much the athlete has urinated that day requires a large amount of compliance and cooperation from the athlete; however, a more qualitative method can be used, such as asking the athlete the frequency of urination during the day 6. Both approaches require a degree of athlete education to ensure that the data collected is accurate.

Measuring urine osmolality involves the collection of urine and using a freezing point osmometer to determine the number of solutes e. NaCl per kg of solution 6. This requires a trained technician and also expensive equipment, though there is an alternative.

The use of a Sparta 5 Conductance Metre has been validated in previous research A 6-point Likert Scale can be used to estimate hydration status through urinary colour Copies of the scale can be distributed between athletes.

This is non-invasive, non-expensive and simple to use, however, the athlete must be educated to ensure that they use to scale correctly and must take note of the results. These methods to estimate hydration status through urinary indices may prove invalid if there are large acute ingestions of fluid after exercise 30, This may produce diluted urine and mask their true hydration status 6.

Methods must be put in place to ensure that hydration testing is completed as soon as possible after exercise so that the data collected is as accurate and precise as possible. Blood Indices It is thought that a number of blood-borne indices can be used to test the dehydration status of an athlete.

Hypertonic dehydration e. from profuse sweating can be detected through changes in plasma osmolality and plasma sodium 30, 32 , whilst hypotonic or isotonic dehydration can be detected through serial haematocrit or haemoglobin measurements This method requires a properly trained professional to ensure that safe and sterile measurements are taken with the appropriate laboratory equipment.

Examples of which are outlined below:. This method of hydration testing can be costly, invasive and labour-intensive 6. Due to the fact that it requires blood sampling, there will always be a risk of infection, bruising and vein damage.

From this study, they concluded that urinary measures may be more accurate during conditions of mild dehydration; which other research supports This could be due to the fact that urine is more concentrated to maintain normal blood chemistry during exercise 6.

Plasma sodium has been found to increase under conditions of dehydration This study aimed to investigate the use of plasma sodium as a marker of dehydration during exercise in heat. It involved 2 hours of cycling 3. Results show an increase in plasma sodium from baseline measurements, and an extra 20 minutes of cycling 1.

One study compared haematocrit and haemoglobin levels to levels of total body water both before and after an exercise intervention lasting 14 days It showed that blood indices correlated with total body water throughout the study, suggesting that these may be useful for situations of hypotonic and isotonic dehydration.

Whilst plasma osmolality, blood sodium, haematocrit and haemoglobin may provide accurate information regarding hydration status, the limitations outlined earlier seem to outweigh the benefits at this point in time.

Further research and engineering are needed to provide a more practical approach when using these measurements. Limitations regarding hydration testing primarily appear to be related to its practicality in the field.

For example, it would be impractical to have an entire AFL or Rugby League team use BIA after every training session or to use USG to estimate hydration level.

BW changes , measurement accuracy will, most likely, be sacrificed. Coaches, fitness and medical staff must communicate what they feel is the most appropriate method for their particular sport.

A further issue with hydration testing can be the priority that this measurement takes in the eyes of the fitness and medical staff. Coaches outside of an elite environment may not have the time or resources to hydration test their athletes, potentially putting their performance and health at risk.

Future research in the area of hydration testing should focus on determining if current methods can be altered so that they can provide an even more valid and reliable measurement as well as addressing the following issues:.

Hydration testing is a very important part of any athletic programme and can prevent serious performance and health deficiencies. There are methods available which are valid, inexpensive and non-time-consuming, but the confounding variables that may affect results must be addressed.

Future research is required to assess whether urinary and blood indices can be used as hydration tests in a practical sense. William is a recent graduate from Deakin University with a Bachelor of Exercise and Sport Science.
