Öğe An Exercise Prescription for COVID-19 Pandemic(Professional Medical Publications, 2020) Aktug, Zait Burak; Demir, Nazlim AktugCOVID-19 is an alarming public health concern worldwide. COVID-19 is highly contagious and has no approved treatment or vaccine yet. Therefore, the best strategy is prevention. Studies have shown that a healthy lifestyle, regular exercise, balanced eating, and quality sleep are the key elements for protection from this disease. We are going through a distressful period as a nation and as the human race in general. We need to manage this period in the best way possible in physiological and psychological terms. Physical activity is one of the major steps in managing this period in a healthy way. Individuals should be provided information about exercise so that they can perform correct physical activities within their means. This article presents an exercise prescription that can be followed in the days of the COVID-19 pandemic.Öğe Do the exercises performed with a theraband have an effect on knee muscle strength balances?(Ios Press, 2020) Aktug, Zait BurakBACKGROUND: In the current literature, exercises performed using fitness equipment and body weight have been used in order to decrease the bilateral deficit (BLD) and increase the hamstring-quadriceps (H/Q) ratio. No studies have previously investigated the effect of therabands, which are both portable and practical to be used anywhere, in regard to the BLD and H/Q ratio. OBJECTIVES: The purpose of this study was to investigate the effect of several 10-week lower extremity exercises performed through therabands on the BLD and H/Q ratio. METHODS: Twenty-seven voluntary male soccer players participated in the study. The players were categorized into the control group (CG) (n = 14) and the theraband exercise group (TBG) (n = 13). Theraband exercises for the lower extremity were performed by the soccer players in the TBG for four days every week over a 10-week period. The dominant (D) and non-dominant (ND) leg concentric extension and flexion of the soccer players were determined through an isokinetic dynamometer at 30 degrees s(-1) and 240 degrees s(-1) angular velocities. The data were analyzed through SPSS 24. To determine the difference between the BLD, H/Q ratios, and pre- and post-test of peak torque (PT), the Wilcoxon test was employed. RESULTS: As a result of the analysis, it was found that the BLD for the TBG decreased, which was statistically significant (p < 0.05), whereas there were no statistically significant differences for the H/Q ratio for both the CG and TBG; the D and ND leg H/Q rate of the TBG at 240 degrees s(-1) angular velocity increased in the post-test. CONCLUSIONS: It was found that the exercises performed with the theraband were extremely efficient at increasing the PT and decreasing the BLD.Öğe Estimating the England Premier League Ranking with Artificial Neural Network(Taylor & Francis Inc, 2021) Aka, Hasan; Aktug, Zait Burak; Kilic, FarukThe aim of this study is to estimate the teams' league rankings at the end of the season by using different parameters peculiar to soccer with artificial neural networks (ANNs). In this study, the values belonging to stealing the ball, number of passes (pass on target, forward pass, and pass before goal scoring), number of possessions during the match, attack time resulting in the goal scoring and number of shots in 1140 competitions played in 2015/2016, 2016/2017, and 2017/2018 England Premier League seasons have been evaluated. Season ranking in the 2017/2018 season has been estimated by analyzing the data in the first two seasons (2015/2016, 2016/2017). All data have been separated randomly for training and test. League ranking has been modeled numerically as 0 and 1. Because the generated value is between 0 and 1, the league ranking has been obtained by multiplying this value by 100 for a trained network. Thanks to the ANN model developed by training and testing according to the findings, the training, validation, test, and all regression values of the English Premier League have been obtained as 0.99779, 0.98123, 0.96981, and 0.98769, respectively. With respect to this result, it has been seen that number of shot, stealing the ball, attack time, and number of possessions parameters are determinant in team ranking at the end of the season along with the other parameters in the England Premier League. We think that analyzing matches with the ANN model provides fast and objective results for team managers, trainers, athletes, and betting shops.Öğe Investigation the effect of weightlifting training on apelin level and hematologic parameters of professional handball players.(Scientific Publishers of India, 2018) Dundar, Aykut; Murathan, Fatih; Aktug, Zait Burak; Servi, TayfunObjectives: Apelin is a member of myokines which has recently been characterized. The purpose of this study was to examine the effects of a weightlifting training (WT) program on some biochemical (glucose, insulin and apelin) and haematological parameters in professional male handball players. It was hypothesized that significant increase would be found in apelin levels of subjects Material and methods: Ten professional handball players (Trained Handball Player Group, THG) completed 6-week WT. Ten sedentary subjects (Trained Sedentary Group, TSG) also completed WT to compare with THG and investigate the effect of being a handball player. Ten subjects have been considered as control group (Control Group, CG). Results: The apelin levels of THG and TSG have been increased significantly (p<0.05) but the increase in THG (55%) is more than TSG (38%). CG subjects did not exhibit any significant changes during the 6-week period (p>0.05). Conclusion: It has been concluded that the WT has an important role on apelin level, especially in professional handball players. © 2018, Scientific Publishers of India.

Materials and Methods: 30 volunteer male athletes who professionally play soccer participated in the study, and the participants were randomly divided into experimental and control groups. The functional performance of the lower extremities, lumbar extensor endurance and mobility of the subjects were measured twice - before and immediately after the Still Technique and placebo applications. Subjects' lower extremity functional performance was determined by the Single Leg Hop Test, lumbar extensor endurance by the Beiring-Sorensen Extensor Endurance Test, and mobility skill by the Modified Schober Test. Results: According to the results of the statistical analysis, there was a significant difference between the pre-test and posttest values of the lumbar extensor endurance tests of the experimental group in favor of the posttest; however, there was no significant difference in lower extremity functional performance and mobility values, and it was determined that they improved in the post-test. Conclusions: Releasing the thoracolumbar fascia tissue with osteopathic technique before exercise in athletes can acutely increase performance by positively affecting muscle contraction.Öğe The comparison of the pulmonary functions of the individuals having regular exercises and sedentary individuals.(SCIENTIFIC PUBLISHERS INDIA, 2016) Marangoz, Irfan; Aktug, Zait Burak; Celenk, Cagri; Top, Elif; Eroglu, Huseyin; Akil, MustafaThe object of our study is to determine the differences between the pulmonary functions of individuals having regular and long-term exercises, and sedentary individuals. The study included 29 athletes having regular and long-term exercises, and 27 sedentary individuals who are not interested in any sports branches actively. The parameters such as Forced Expiratory Volume in 1st Second (FEV1), Forced Vital Capacity (FVC), Peak Expiratory Flow (PEF), Vital Capacity (VC), and Maximum Voluntary Ventilation (MVV) of the individuals included in the study have been examined and the results have been analysed with MIR MiniSpir (Via del Maggiolino Roma-Italy) Spirometer. The arithmetic means and standard deviations of data have been obtained in the statistical evaluation. As a result of the findings obtained, Independent Samples t-test has been applied. No significant difference has been found among the age, height, body weight, Body Mass Index (BMI), FEV1 and PEF values of the groups at the end of the test (P>0.05); however, a significant difference has been found among MVV, FVC, and VC values (P<0.05). When the results of the study are evaluated in accordance with literature data, it has been found out that no difference is present between the FEV1 and PEF values of individuals having long-term and regular exercises, and sedentary individuals; however, there is a significant difference among MVV, FVC and VC values. Therefore, it has been found out that the pulmonary functions (MVV, FVC, and VC) of individuals having regular exercises have improved better than that of sedentary individuals.Öğe The Effect of Combining Blood Flow Restriction with the Nordic Hamstring Exercise on Hamstring Strength: Randomized Controlled Trial(Mdpi, 2024) Piskin, Necdet Eray; Yavuz, Gonul; Aktug, Zait Burak; Aldhahi, Monira I.; Al-Mhanna, Sameer Badri; Gulu, Mehmet(1) Background: It is a matter of curiosity what effect the blood flow restriction (BFR) method, which is usually combined with low-intensity resistance exercises, will have when used with high-intensity eccentric exercises. (2) Methods: The present study examined the effects of combining BFR with nordic hamstring exercises (NHEs) on hamstring muscle strength, bilateral deficit (BLD), and training volume. Thirty young female volleyball players, who trained three times a week, participated voluntarily in the study. These players were stratified into three groups, each comprising ten individuals: a control group (CG), an NHE group, and an NHE + BFR group. Hamstring muscle strength and BLD values were determined using an H-BORD device, while training volume was measured in terms of sets and repetitions. (3) Results: Statistical analysis revealed that there were no statistically significant differences in non-dominant and dominant leg peak torque parameters in the exercise groups (F = 2.65; p = 0.097; eta p2 = 0.17; F = 1.15; p = 0.0334; eta p2 = 0.084), while the total training volume was lower in the NHE + BFR group. (4) Conclusions: As a result, it was seen that adding the BFR method to NHE did not provide additional gains. However, due to the low training volume of BFR + NHE, it may be recommended to apply BFR together with NHE to athlete groups.Öğe The effect of fatigue in elite young female wrestlers upon balance performance and reaction time(SCIENTIFIC PUBLISHERS INDIA, 2016) Iri, Ruchan; Aktug, Zait Burak; Koc, Mustafa; Sahin, Ibrahim; Murathan, FatihThe purpose of the study was to investigate the effect of fatigue in Turkish National Team Young Female Wrestlers upon balance performance and reaction time. Totally 17 female wrestlers with 18.58 +/- 2.26 years age average, 165.65 +/- 6.88 cm height average, 62.55 +/- 9.35 kg weight average, and 22.53 +/- 2.03 kg/m(2) body mass index were included into the study voluntarily. The wrestlers participated into the research were asked to make a match in accordance with the real conditions. Static-dynamic balance performance and reaction time tests were performed to the female wrestlers as rested before and as fatigue after the match. Static-dynamic balance measurements of the wrestlers were determined using Biodex Balance System, visual reaction time measurements were determined using MOART Lafayette Reaction Measurement Device, and fatigue levels were determined using handheld Lactate analyser. Whereas negative relationship (p<0.005, r=-0.577) was found between after match (fatigue) lactate level and after match static balance (p<0.005, r=-0.505) and dynamic balance, after match lactate level was determined not to have a significant relationship with after match reaction time (p>0.005, r=0.395). Consequently, the balance skill as one of the most important requirements of high performance in wrestling was determined to deteriorate through the increase at fatigue level. Moreover, although no significant relationship was found between fatigue and reaction time, the time for fatigue reaction time was noticed to be higher rather than rested reaction time.Öğe The effect of lower extremity masses and volumes on the balance performance of athletes(SCIENTIFIC PUBLISHERS INDIA, 2016) Akil, Mustafa; Celenk, Cagri; Aktug, Zait Burak; Marangoz, Irfan; Yilmazi, Taner; Top, ElifOur study aims to investigate the effects of lower extremity mass and volume characteristics of elite athletes on the balance performances. The study has included 42 elite athletes totally with an average age of 23.45 +/- 2.50 years, average height of 173.64 +/- 6.96 cm, average weight of 79.55 +/- 14.19 kg and average body mass index of 26.22 +/- 3.06. The calf, femur, foot and leg volumes of the subjects included in the study have been determined by means of Frustum method however, calf, femur, foot and leg masses of the subjects have been determined by means of Hanavan method. The static and dynamic balance performance of athletes has been measured by Biodex Balance System. Dynamic balance performance has been detected in the levels of 2, 4 and 8. When dynamic balance performances have been evaluated, it has been found that there is a significant difference in low-level balance test (p>0.05), and a positive difference has been found between the masses and volumes of calf (r=0.437), femur (r=0.609), foot (r=0.344) and leg (r=0.607) in terms of good and moderate level of balance performances (p<0.05). According to the results obtained, the masses and volumes of calf, femur, foot and leg of the athletes have affected the balance performances and, as the difficulty level of the balance performance increases, the lower extremity mass and volumes affect the balance performance much more. In conclusion, it has been found that lower extremity masses and volumes affect the balance performance of the athletes positively, and lower extremity mass and volumes are required to be improved enough in the branches that put an emphasis on balance.Öğe The Estimation of the Set Results in 2016/2017 Vestel Venus Sultans League Games by Artificial Neural Network(Univ Extremadura, Fac Ciencias Deporte, 2021) Aka, Hasan; Akarcesme, Cengiz; Aktug, Zait Burak; Ozden, SemihThe objective of this study is to estimate the set result via Artificial Neural Network (ANN) by considering the scores of the volleyball teams at technical time-outs (8th and 16th points) and 21st point. In the study, 132 games, 984 sets and 4152 points that were played and scored during a season by 12 teams playing in 2016/2017 Vestel Venus Sultans League were examined separately. 85% of all sets that teams played in one season were randomly reserved for training and 15% for test. Verbally winning or losing was modeled as 0 (zero) or 1 (one) numerically. Since the produced value was between the ranges of 0 - 1, for a trained network, it was multiplied with 100 and thus the possibility of winning was obtained. Consequently, it was determined that the developed model estimated the set result for many teams (test dataset) with an accuracy rate over 95%. By means of competition analysis to be made using ANN model in volleyball, it is thought that technical officers can reach fast and accurate conclusions at the moment of the set is played. It can be said that these conclusions will provide technical officers with a warning mechanism to take necessary technical and tactical measures while the set is being played.
