(2018-01-01) Ceylan B.; Gurses V.; Akgul M.; Baydil B.; Franchini E.
Background. Judo is an Olympic sport where physical fitness is of great importance as well as technique and tactics. Physical and physiological conditions of the athletes are very important for a better judo performance and there is still a need for more data related to these determinants. Problem and aim. There is a need for more data concerning anthropological determinants of judo athletes. Thus, the aim of this study was to evaluate anthropometric profile, Wingate and Special Judo Fitness Test (SJFT) performance. Methods. The following tests and measurements were conducted in order to investigate anthropometric profile, Wingate and Special Judo Fitness Test (SJFT) performance of male (n=7) and female (n=10) judo athletes from Turkish Olympic judo team: anthropometric measurements, Wingate anaerobic test (WanT) and SJFT. An independent Student t test was used to compare male and female athletes. Pearson product correlation was used to verify the relationship between variables. Effect sizes were calculated following the recommendations by Rhea (2004). Results. There were differences between male and female athletes in the following variables; fat-free mass, body fat percentage, peak and mean power, HR after the set A and in the SJFT index (p < 0.05).Large and very large correlations were found between anthropometric measurements, SJFT parameters and WanT performance results (p < 0.01). Large correlation was found between fat-free mass and HR values during SJFT sets (p < 0.05). Conclusions. It can be concluded that the higher the fat percentage, the lower is the performance in activities involving body displacement. In conclusion, sex and weight differences should be taken into consideration while evaluating judo athletes and because higher fat-free mass means better SJFT performance, the training program should be organized to decrease or maintain body fat and increase muscle mass.
Dehydration and acute weight gain of athletes before sport competitions
(2018-01-01) Gurses V.V.; Ceylan B.; Sakir M.; Baydil B.; Hussein H.A.; Badau D.
The aim of this study was to evaluate the extent of acute weight gain, dehydration and rehydration in judo athletes before official competitions. The results showed that judo athletes are competing in dehydrated conditions and thus preventive measurements should be taken to prevent athletes’ disadvantageous health circumstances related to acute weight gain and dehydration.
Differences among three measures of reaction time based on hand laterality in individual sports
(2018-06-01) Badau D.; Baydil B.; Badau A.
(1) Aim: The study aimed at assessing simple-reaction, recognition and cognitive-reaction times to visual stimuli among student athletes: boxing, gymnastics, taekwondo, judo, karate and wrestling, using computer games tests. (2) Methods: Our study involved 332 students and athletes. We applied three types of computer tests to measure the dominant and non-dominant hands: the simple motor reaction time through the Human Benchmark test, the recognition time by the Hit-the-dots and the cognitive reaction time by the Trail making test part B. (3) Results: For dominant and non-dominant hands, better results of individual sports were for: simply reaction time—boxing; recognition reaction time—taekwondo; cognitive reaction—judo. (4) Conclusions: Athletes had better simple reaction with the left hand than with the right hand. Athletes had better recognition and cognitive reaction time with the right hand than with the left hand regardless of the dominant hand. The outcomes of our study indicate that the reaction times of left and right hands were influenced by the hand laterality, the type of applied stimulus, the stress complexity of tests and the type of practiced sport.
Physiological impact of wearing a surgical face mask during walking in the covid-19 pandemic
(2021-01-01) Akgul M.S.; Ozcan N.; Uzun M.E.; Gurses V.V.; Baydil B.
Background and Study Aim Common use of surgical face masks is recommended for social and individual health due to the COVID-19 pandemic. However, there is no systematic report for responses of organism to wearing a surgical face mask during different exercises. In this context the purpose of this study was to examine the impacts of wearing a surgical face mask during a one-hour brisk walking. Material and Methods A total of thirty male (n=16) and female (n=14) volunteers (mean age and BMI of 32±1.07 years and 25.1±0.68 kg/m2, respectively) completed the protocol. This was a multiple cross-over trial for healthy volunteers. All participants took a one-hour brisk walking with and without a surgical face mask. Specific physiological measurements (HR-heart rate; BP-blood pressure, SaO2-arterial oxygen content) were compared before and immediately after two brisk walking. Each subject served their own control. Results The evaluation found that there was no statistically significant difference between the mean HR and blood pressure values during the brisk walking with and without a surgical face mask, while there was a statistically significant difference in the SaO2 values on behalf of no-mask-walking (p<0.05). Conclusions: The use of surgical face masks in healthy volunteers causes a decrease in SaO2 during brisk walking. However, it does not affect the mean pulse rate and blood pressure. Although there was a statistically significant decrease in the SaO2 parameter during mask-walking, it is possible to state that brisk walking with a surgical face mask does not have a physiologically negative impact, because this decrease is in ranges that are accepted to be normal.
Serum macro-micro element responses to acute maximal physical exercise
(2013-07-30) Baydil B.
Purpose: In this study, it was aimed to examine the effect of acute maximal physical exercise on some macro - micro element levels in women. Method: Blood samples of subjects were drawn 2 times in total; shortly before and after the exercise. The flame atomic absorption spectrophotometric method used for analysis of zinc, calcium, magnesium and copper levels. Serum sodium and potassium concentrations were measured using ion selective electrodes. Results: It was found that there was significant increases for the zinc, calcium, magnesium, potassium and significant decrease for copper (p<0.01) while non-significant difference was found for the sodium parameter (p>0.01). Conclusion: As result our findings show that acute maximal physical exercise can lead to some changes on mineral metabolism in human. Such a diversity of results in the literature, indicate the importance of factors such as duration and intensity of exercise, fitness status of the participants, pre-exercise levels of mineral etc. © IDOSI Publications, 2013.

Weigh-in time affects hydration status and acute weight gain in combat sports: A comparison of judo and wrestling
(2021-01-01) Ceylan B.; Baydil B.; Aydos L.
This study aimed to investigate the effect of weigh-in time on hydration status and acute weight gain (AWG). Twenty-seven men judo athletes and 23 men wrestlers voluntarily participated in this study. Body mass and urine specific gravity (USG) of the athletes were measured just before official weigh-in and competition. Two-way analysis of variance (split-plot ANOVA) with repeated measurements (time x sport) were used to determine differences in AWG and USG between groups and measurement times. In case of significant difference between sports, t-tests were applied. There was a significant main effect of time (p<0.01, ES=0.25) on USG. A significant difference was found in USG between official weigh-in and start of the competition in wrestlers (p<0.01) but not in judo athletes. There was significant difference in AWG and AWG% between sports (p<0.01). Moreover, most of the athletes presented high level of dehydration before both official weigh-in and competition. In conclusion, judo athletes could not rehydrate as much as wrestlers despite 15h of recovery. It can be suggested that the period between official weigh-in and competition would be shortened to prevent non-optimal hydration status and rapid weight gain, with caution to allow sufficient recovery period.
