    The effect of liquid losses in trainings during competition period on some biochemical values of u18 male judokas ( age 15-17)
    (Natl Olympic Committee Ukraine, Kharkov Regional Branch, 2017) Celik, Nuri Muhammet; Beyleroglu, Malik; Soyal, Mehmet; Ciris, Vahit
    Purpose: The purpose of this study is to investigate the effect of liquid losses occurring in training sessions during the competition period on some biochemical values of the male Judokas competing in the U18 category. Material: The values of the 17 male athletes, who were included in the national team at least once, were checked in our study which compares the values of athletes before the competition and immediately after the competition. Urine Density, Urine pH, BUN, Creatine and Potassium values from the biochemistry values were measured besides the age, height and weight of the athletes participating in the study. Results: As a result of the measurements made; it was found that the kg pre-test averages of the participant athletes were 67,82 +/- 17,87, post-test averages were 64,88 +/- 16,89, Urine Density pre-test averages were 1.017,94 +/- 7,08, post-test averages were 1.025 +/- 8,48, Urine pH pre-test averages were 6,15 +/- 0,70, post-test averages were 5,82 +/- 0,50, BUN pre-test averages were 15,65 +/- 3,14, post-test averages were 24,35 +/- 3,60, Creatine pre-test averages were 0,48 +/- 0,20, post-test averages were 0,93 +/- 0,41, K Potassium pre-test averages were 4,16 +/- 0,35, post-test averages were 4,95 +/- 0,64. As a result of the statistical analysis, although there was no significant difference in urine pH pretest and post-test values, statistically significant difference was found between pre-test and post-test values in other selected parameters (p <0,05). Conclusions: As a result; it is thought that in our country in which the adjustment of the weight class is made unconsciously and unplanned, this will lead to the health problems of the athletes in many ways, especially in the later ages. Particularly in the professional sense, the health problems, which athletes who enter weight competitions and who enter at least 10 international competitions in the Olympic sense for the Judo branch a year can experience in the later ages as a result of such exhaustion, should be well considered. The the significant differences in studies in the literature and in our work also indicate that acute and rapid dehydration causes athletes to be harmed in terms of health and leads to the loss of performance. The result of our study is that the athletes should be prompted for weight control in a planned way to prevent the adjusting weight by acute and excessive dehydration.

    The Relationship between the Isocapnic Buffering Phase and Ventilatory Threshold in Endurance Athletes and Team Sport Athletes during an Incremental Exercise Test
    (Annals Applied Sport Science, 2018) Eryilmaz, Selcen Korkmaz; Polat, Metin; Soyal, Mehmet; Aydogan, Sami
    Background. There is sparse literature examining the ICB phase of aerobic-and anaerobic-trained athletes. Measurements of ICB phase values of athletes can help to evaluate the sport's physiological demands and understand the physiological adaptations in response to physical training. Objectives. The purpose of this study was to examine the relationship between the isocapnic buffering (ICB) phase and the maximal oxygen uptake (VO2max) as well as the ventilatory threshold (VT) in trained athletes. Methods. Twenty-eight male endurance athletes and forty male team sports athletes underwent an incremental treadmill test to determine their VT, respiratory compensation point (RCP), and VO2max. The ICB phase was calculated as the difference in Oxygen uptake (VO2) between the RCP and VT and expressed in either absolute or relative values. Results. The VO2max, maximal running speed, time to exhaustion, VO2 at the VT and RCP, running speed at the VT, and VT expressed as % VO2max was higher in the endurance athletes than in the team sport athletes (p < 0.01), whereas the RCP expressed as % VO2max and running speed at the RCP showed similar values in both groups (p > 0.05). Both the absolute and relative ICB phase values were found to be significantly higher in team sports athletes than in endurance athletes (p < 0.001). The relative ICB phase was significantly negatively correlated with the VO2max (-r = 0.517, p < 0.001), the VO2 at the VT (-r = 0.755, p < 0.001), and the VO2 at the RCP (r = -0.517, p = 0.001). Conclusion. The current findings suggest that, for trained athletes, the magnitude of the ICB phase is more closely related to the VT rather than the VO2max and RCP. Presumably, the high-intensity intermittent-type exercises performed by team sports athletes may have improved their buffering capacity, leading to a shift in the RCP without a change in the VT, and consequently enhancing the ICB phase.
