- Abstract
Background. Proper level of hydration during sports is essential factor that affects efficiency of an organism and therefore impacts the athlete's results. Orienteering is finding one's location and moving between checkpoints marked on a map. Due to its specificity, the discipline brings a lot of limitations for fluid intake and keeping the proper level of hydration. The aim of the study was to evaluate the hydration level and average degree of dehydration among the runners whilst performing the sport in correlation to the terrain they were moving around. Methods. The study was conducted in the period from December 2017 to February 2018. The test group consisted of 42 runners. The competitors made two 10km long running trials. The first test took place in a moderately flat terrain and the second trial took place in a moderately mountainous area. Before each of the running tests participants completed a short proprietary questionnaire on hydration aspects of the trial day. Before the running tests, each participant of the study was subjected to anthropometric measurements. Results. Among 56% of runners, BMI values indicated abnormal body weight - overweight or obese. Before participating in the flat terrain trial, the subjects drank an average of 746.67ml. Then, during the run, their body weight decreased on average by 1.12% compared to the body weight before the test. Before participating in the trial in a mountain area, the average fluid consumption was 419.23ml. The average percentage weight loss during the mountain run in relation to the body weight before the test was 1.24%. The hydration level was determined by marking the number in the questionnaire that corresponded to the urine color produced before the running test. Most of the runners showed an incorrect hydration status before the run, both in the flat terrain (n = 24, 61.54% improperly watered) and in the mountain terrain (n = 23, 58.97% improperly watered). Conclusions. Most of the runners ran with a water shortage or dehydrated, and therefore drank too little fluids. Moreover, the athletes dehydrated similarly in both trials, but slightly more in the mountain run; for competitors who were not properly hydrated prior to the run in the mountains, the percentage weight loss was higher than for competitors who were hydrated prior to that race. Measurements of body circumference and skin-fat folds may be helpful in testing athletes' dehydration.
