“…There are also changes in the specific gravity of urine, which increases as a result of exhaustion and increase in water loss. The following changes were noted in the study by Jablan (2017). Immediately after exercise, the osmolarity was 1.03 ± 0.006, to change slightly after 1.0 hours to 1.03 ± 0.007.…”

“…To have a full picture of the changes taking place, the copper concentration was also measured. Its urine concentration remained high compared to baseline, while iron levels (although above normal) tended to decrease (Jablan, 2017). Cobalt helps in the absorption of iron, which in turn leads to increased body efficiency.…”

“…A significant increase in the level of minerals, i.e. calcium, phosphorus, potassium and sodium in the urine of participants of mountain ultramarathon was observed immediately after the run, with a constant increase in the concentration of calcium and phosphorus, a slow decrease in the concentration of potassium and a variable level of calcium (Table 1), after the period of 24. hours (Jablan, 2017).…”

“…However, in studies conducted by Jablan (2017), an increase in the level of trace elements (Table 1) in the antioxidant defense system (Se, Zn and Mn) was observed, which increased immediately after the race and returned to baseline after the observation period (24 hours). This could reflect a higher synthesis of antioxidant enzymes as an adaptive response to oxidative stress that occurred during endurance activity (Jablan, 2017).…”

During long lasting physical exercise and physical training, a large number of changes occur in the human body. The body homeostasis is disturbed, and observed changes include kidney function. The most common observed symptom is a decrease in the amount of urine excreted due to an increase in the secondary absorption of water during exercise. During long lasting physical exercise the filtration in the glomeruli is impaired, and thus the composition of urine is changing. Differences in the amount of minerals excreted are noted, as a result of water loss, and urine osmolarity increases. Those changes are depend largely on the type of undertaken physical activity, its duration, as well as the individual predisposition of the examined physical active human. Therefore, in individual studies, the results differ significantly, and it is impossible to draw unequivocal conclusions.

Exposure to toxic metals and metalloids is a significant public health concern and can seriously affect human health. The aim of this study was to establish the presence of toxic metals and metalloids in the urine of non‐professional sportsmen who participated in a mountain ultramarathon using a benchtop total reflection x‐ray fluorescence (TXRF) system. TXRF allows for easy and rapid sample preparation and is therefore a potential candidate for simple and cost‐effective analysis. In this work, the TXRF‐Mo system was used for multielement analysis of the urine samples of 21 non‐professional athletes who ran a 53 km mountain ultra‐marathon. Urine samples were collected at four time points, at the beginning of the race (pre‐race samples), immediately, and 12 and 24 h post‐race. Al, As, Ba, Ni, Pb, Rb, Sr, V, and Tl were detected in the collected urine samples. The accuracy and precision of the proposed methods were verified by the analysis of reference materials (Seronorm™ Trace Elements Urine Level 2). The TXRF results were in agreement with the reference values and no significant differences were observed at the 95% confidence level. The detection limits for the elements of interest were also reasonable considering their concentration ranges in real samples. Changes were observed over time with increasing average urinary metals and metalloids levels, but only two significant results, were an increase in As and Rb. The results indicate a high degree of inter‐subject variability. The results obtained show that the content of toxic metals and metalloids increases in the urine samples collected after the race, which could confirm the statement that physical activity can increase the excretion of toxic metals and metalloids from the body. The simplicity of the TXRF method as well as its fast performance make it suitable for routine analysis.
