Öğe Analysis of the influence of somatotype difference on motoric parameters such as vertical jump, sit and reach flexibility and 30-m sprint(Edizioni Minerva Medica, 2018) Senol, Deniz; Ozbag, Davut; Kafkas, Muhammed E.; Acak, Mahmut; Baysal, Ozlem; Sahin Kafkas, Armagan; Taskiran, CelalBACKGROUND: The purpose of this study is to show the somatotype features of young people with no symptoms and to find out whether motoric parameters such as vertical jump, flexibility and 30-m sprint were influenced by somatotype differences. METHODS: The study included 146 participants (88 males, 58 females) who had no symptoms. The Heath-Carter formula was used to find out the somatotypes of the participants and each participant's anthropometric measurements were found. Vertical jump, flexibility and 30-meter sprint test were measured to evaluate motoric parameters of male and female. RESULTS: In men, athletes with central type somatotype had the best score in vertical jump test with 53 cm, athletes with endomorphic mesomorph somatotype had the best score in sit and reach flexibility test with 30 cm, and athletes with balanced mesomorph somatotype had the best score in 30-m sprint test with 4.36 s. In women, athletes with endomorphic mesomorph somatotype had the best score in vertical jump test with 40 cm, athletes with Endomorphic Mesomorph somatotype had the best score in sit and reach flexibility test with 33.5 cm, and athletes with mesomorph endomorph somatotype had the best score in 30-m sprint test with 5.22 s. No statistically significant difference was found in male and female between different somatotypes and motoric parameters (P>0.05). CONCLUSIONS: Although there were no statistically significant differences, it emerged that different somatotypes were more successful than others. An anatomic body structure specific for the sport branch influences performance greatly.Öğe Analysis of the influence of somatotype difference on motoric parameters such as vertical jump, sit and reach flexibility and 30-m sprint(EDIZIONI MINERVA MEDICA, CORSO BRAMANTE 83-85 INT JOURNALS DEPT., 10126 TURIN, ITALY, 2018) Senol, Deniz; Ozbağ, Davut; Kafkas, Muhammed E.; Acak, Mahmut; Baysal, Özlem; Şahin Kafkas, Armağan; Taşkıran, Celal; Özen, GökmenBACKGROUND: The purpose of this study is to show the somatotype features of young people with no symptoms and to find out whether motoric parameters such as vertical jump, flexibility and 30-m sprint were influenced by somatotype differences.

Neuro performance study on healthy individuals(2019) Senol, Deniz; Kisaoglu, Aysegul; Canbolat, Mustafa; Calisgan, Elisa; Acak, Mahmut; Duz, Serkan; Ozbag, DavutAim: The purpose of this study is to find out whether visual and auditory reaction time (VRT and ART) is influenced by Ramadan fasting in healthy individuals in terms of neuro performance. Materials and Methods: 60 healthy individuals (30 male, 30 female) with the mean age of 20.22±1.45 years participated in the study. First reaction measurement was collected on the second week of the date Ramadan fasting started and this period was called fasting period. Second reaction measurement was collected five days after Ramadan fasting ended and this period was called post-fasting period. VRT and ART of the samples who participated in the study were made with reaction timer device. 10 trials for sound and light stimuli were taken from each sample. The first five trials were considered as exercise and the average of the last five trials was determined as reaction time. The analysis of VRT and ART in fasting and post-fasting periods was conducted with Wilcoxon matched pairs test. In addition, Mann Whitney U test was used to analyze whether there were differences between fasting and post-fasting periods of males and females in terms of VRT and ART. Results: No statistical difference was found between the VRT and ART of males and females in fasting and post-fasting period (p>0.05). Conclusion: In this study which examined the effect of fasting on VRT and ART, it was found that males and females who participated in this study were not negatively influenced by Ramadan fasting in terms of neuro performance.Öğe The clinical effects of somatotype difference on isokinetic knee muscle strength and dynamic balance scores(Baycınar medıcal publ-baycınar tıbbı yayıncılık, ornek mh dr suphı ezgı sk saray apt no 11 d 6, atasehır, ıstanbul 34704, turkey, 2018) Şenol, Deniz; Özbağ, Davut; Kafkas, Muhammed Emin; Acak, Mahmut; Baysal, Özlem; Kafkas, Armağan Şahin; Taşkıran, Celal; Çay, Mahmut; Yağar, Derya; Özen, GökmenObjectives: The aim of this study was to present the somatotype features of young individuals without any symptoms and to identify whether isokinetic knee muscle strength and dynamic balance scores are affected by somatotype difference. Patients and methods: A total of 146 participants (88 males, 58 females; mean age 22.5 +/- 1.9 years; range 19 to 28 years) who had no symptoms were included in this study. Somatotypes of the participants were calculated using the Heath-Carter formula, and anthropometric measurements were taken from each participant. Knee flexion and extension muscle strengths at angular speeds of 90 degrees/sec, 120 degrees/sec and 150 degrees/sec were measured from the dominant and non-dominant limbs of the participants. Total balance, anterior/posterior balance, and medial/lateral measurements were made to evaluate dynamic balance performances. Results: Six different somatotypes were found. Endomorphic mesomorph was the most common somatotype in 56 participants. There was no significant somatotype difference in men and women for dominant and non-dominant knee extension and flexion peak strength values at angular speeds of 90 degrees/sec, 120 degrees/sec and 150 degrees/sec (p>0.05). No significant difference was found between the balance scores of men and women who had different somatotypes (p>0.05). Conclusion: Anatomic structure of the body, which is suitable for the sports branch, has an increasing effect on performance.Öğe The clinical effects of somatotype difference on isokinetic knee muscle strength and dynamic balance scores (vol 64, pg 28, 2018)(Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2020) Senol, Deniz; Ozbag, Davut; Kafkas, Muhammed Emin; Acak, Mahmut; Baysal, Ozlem; Kafkas, Armagan Sahin; Taskiran, Celal[Abstract Not Available]Öğe Deaf Athlete: Is There Any Difference Beyond The Hearing Loss?(Expert Projects Publishing, 2016) Akgul Ercan, Ebru; Kilic, Alparslan; Savas, Seyfi; Acak, Mahmut; Biyikli, Zeynep; Tore, Hasan FehmiRegular physical activity and sport is important for enhanced physical fitness and skill performance of deaf athletes. However there are few data in the literature about their medical considerations. In this study we aimed to determine the morphological findings and cardiac status of the deaf athletes and compare then with the normal ones. Thirty deaf and twenty-two normal male athletes without cardiovascular diseases participated in the study. Transthoracic echocardiography and exercise stress testing were performed. Tissue Doppler imaging (TDI)-derived myocardial performance index (MPI) was also evaluated. VO2 max and heart rate recovery were calculated after exercise stress testing. Total cholesterol, LDL and trigliseride levels were significantly increased in the deaf athletes, but they were still found to be in normal ranges according to age and risk factor profile (p<0.05). End-diastolic diameter and left ventricular mass index were found to be significantly increased in the controls when compared with the deaf athletes (p<0.001). Heart rate recovery at 1 minute did not show any difference in the deaf group when compared with the control group (p>0.05). MPI calculated from TDI-derived variables was found to be 0.41 +/- 0.073 in the deaf group and 0.46 +/- 0.061 in the controls respectively and significantly decreased in the deaf (p<0.05). Beyond having a hearing loss, the deaf athletes have many cardiac structural and functional differences from their normal counterparts. The factors that give rise to these differences have to be revealed by further research.Öğe Development of the Effect of Video Assistant Referee Application on Football Parameters(Mdpi, 2022) Buyukcelebi, Hakan; Duz, Serkan; Acak, Mahmut; Nalbant, Umut; Svatora, Karel; Gabrys, Tomasz; Karayigit, RaciThe Video Assistant Referee (VAR) application is a technological development that gives referees the chance to review their critical decisions. The current study aimed to determine the effect of the VAR system in international football organizations on the game over the years. The sample of the study consists of 115 football matches, specifically 64 matches played in the 2018 FIFA World Cup and 51 matches played in the 2020 European Football Championship. In the competitions handled, the number of goals, the number of yellow cards, the number of red cards, the first half time, the second half time, the total match time, the number of penalties and the number of offsides were examined. The Mann-Whitney U test was used to compare two independent groups. As a result, in the 2020 European Football Championship, there was a decrease in the second half time (p = 0.01) and total match time (p = 0.01), and a significant increase in the number of offsides (p = 0.03) compared to the 2018 FIFA World Cup. On the other hand, there was no significant difference between the two tournaments in the variables of number of goals, number of yellow cards, number of red cards, half time and penalty shootout (p > 0.05). In light of the data obtained, it can be said that the effect of the VAR system on the spirit of the game will decrease as the share of the VAR system in the pauses during the competition decreases over the years. The data revealed in the study may be a clue to explaining why the effect of the VAR system on game dynamics and game spirit has decreased over the years. Therefore, the concerns of football stakeholders about the effects of the system on the game may gradually decrease with the arrangements made for VAR.Öğe The Effect of Electrical Muscle Stimulation (EMS) Enhanced Schroth Method Training on Cobb Angle and Quality of Life in Patients with Scoliosis(Lahore Medical Research Center Llp, 2022) Kurak, Kemal; Altunhan, Abdullah; Acak, Mahmut; Korkmaz, Mehmet Fatih; Duz, SerkanAim: Different treatment models are applied in cases that affect the quality of life of individuals with scoliosis. It has been stated that exercise applications, especially used in addition to physical therapy, are effective in the treatment process of patients with scoliosis. In recent years, Electrical muscle stimulation (EMS) has been used to increase the performance of athletes. Accordingly, this study was planned to examine the effect of Electrical muscle stimulation (EMS) application on scoliosis cobb angle and quality of life in patients with scoliosis. Methods: Twenty-four female scoliosis patients with scoliosis Cobb angle between 250 and 400 in the thoracic region between the ages of 14-26 participated in the study. The patients participating in the study were divided into three different groups as EMS Schroth exercise group (EMSS=8), Schroth exercise group (SE=8) and control group (CG=8). In addition, height, body weight, body mass index (BMI), Cobb angle measurements were taken for each group before and after the study. Scoliosis Research Society 22 scale (SRS-22) was used for these measurements. SPSS 25 statistical package program was used to evaluate the data. Since the data were not normally distributed, Mann Whitney U-test was used for pairwise comparisons. Kruskal Wallis H-tests were used to compare more than two groups. The level of significance was accepted as P<0.05 in the evaluations. Results: It was determined that there was no statistically significant difference between the age, weight, height and BMI of the EMSS, SE and CG participants and it was found that the EMSS cobb angle decreased statistically. Also, it was stated that there was a stable and very slight decrease in the SE cobb angle. It was determined that there was a statistically significant difference in the negative direction in the CG cobb angle. It was determined that there was a significant change in SRS-22 scale values in all sub-dimensions of EMSS and SE, and there was no statistically significant difference in the pre-test and post-test mean scores of the other sub dimensions except the pain sub-dimension of the CG scale. Conclusion: EMS exercises will save time in terms of faster recovery of patients in the treatment of scoliosis. Besides, it will be very beneficial in terms of time and cost by shortening the rehabilitation period of athletes after sports injuries.Öğe The Effect of Plyometric Training Combined with Electrical Muscle Stimulation on Sports Performance Parameters in Basketball Players(2021) İlbak, İsmail; Acak, MahmutToday, there are various training methods used to increase athletic performan- ce. One of these methods is artificial electrical muscle stimulation (EMS) used as strength maintenance and development training. The objective of the study is to examine the effects of plyometric training applications combined with EMS on sportive performance in basketball players. A total of 20 basketball players between the ages of 15-20 participated in the research. Participants were randomly divided into two equal groups: plyometric (PA) and plyometric training combined with EMS (PEMS). At the beginning and end of the study, the participants’ height, body weight, vertical jump, 20m sprint, agility, balance and repeated sprint performance measurements were taken. In the findings of the study, there was a statistically sig- nificant difference between the pre-test and post-test scores of the PEMS and PA groups, among all sportive performance parameters. However, it was determined that there was no statistically significant difference between the groups in vertical jump, balance, agility, 20m sprint and repeated sprint performances. As a result, it can be said that both plyometric training and EMS training combined with pl- yometric training are two effective methods that can be used to improve sportive performance.Öğe The Effect of Plyometric Training Combined with Electrical Muscle Stimulation on Sports Performance Parameters in Basketball Players(2022) İlbak, İsmail; Acak, MahmutToday, there are various training methods used to increase athletic performan- ce.

Designed insoles was adjusted according to height, length and function of the sole of each participant with pes planus in order to improve the physical parameters of them. A total of 34 participants (17 males and 17 females) with pes planus participated in the study. Height, weight, percent body fat, 30-m sprint test, vertical jump, 12-min Cooper test and Visual Analog Scale (VAS) measurement were obtained before the study and after 1 year later. Wilcoxon signed rank test was conducted to examine whether there were any differences between the pre- and post-test measurements. It was determined that individually designed insoles reduced body weight and BMI, made positive improvements in 30-m speed, vertical jump and 12-min Cooper scores, and significant decrease in VAS scores. In conclusion, it is seen that individually designed insoles have beneficial role in normalizing forces acting on the foot and improve the physical performance parameters of individuals with pes planus. Future studies are needed to explore the long-term effects of individually designed insoles and prefabricated insoles.Öğe THE EFFECTS OF KINESIO TAPING ON LATERAL EPICONDYLE PAIN AND HANDGRIP MUSCLE STRENGTH DURING TENNIS TOURNAMENT(Univ Zagreb, Fac Kinesiology, 2017) Kafkas, Muhammed Emin; Kafkas, Armagan; Durmus, Bekir; Acak, Mahmut[Abstract Not Available]Öğe THE EMOTIONAL INTELLIGENCE OF STUDENTS WHO ARE SITTING A SPECIAL-ABILITY EXAMINATION(Soc Personality Res Inc, 2010) Coban, Bilal; Karademir, Tamer; Acak, Mahmut; Devecioglu, SebahattinWe aimed to detect the differences in emotional intelligence in young people according to some sociodemographic variables. A total of 170 people who were sitting a special-ability examination in order to gain a place in the physical education and sports teaching department at a university formed the sample. We found that there were statistically significant differences in emotional intelligence levels according to the variables of age, hometown, participation in social and sports activities, self-description, and description of family, as well as in the behaviors of the families towards the adolescent. There were no significant differences according to gender, alma mater, or the income level of the family.Öğe The impact of existing and modify wrestling shoes on foot posture deformities in 12-13 years old athletes(Iermakov S S, 2022) Coskuner, Zeki; Acak, Mahmut; Buyukcelebi, Hakan; Ozen, Gokmen; Kurak, KemalBackground and Study Aim In the early years when sports footwear became compulsory, the importance of shoe design was not considered in terms of athletes' health. Since the early years of wrestling shoe use, these gears have been manufactured according to the rules of competition, and modifications have been very limited. In this regard, this study aims to determine the effect of existing wrestling shoes on foot deformation. Material and Methods The study was carried out with the participation of 108 young male athletes who had the same training on the same ground for three years in the Wrestling Training Center. The athletes were divided into two groups, an experimental and a control group. While the control group wore wrestling shoes produced by widely used brands, the experimental group wore newly designed wrestling shoes. Foot arch values and images of both groups were determined using a podoscope device at the beginning and end of the study. The evaluations were made according to the Staheli arch index. Results The results of the statistical analysis revealed that differences were found in the footprint measurement values of the control group. It was determined that this difference in the footprints was greater among the freestyle wrestlers. The decrease in the averages between the first and second measurement values of the group using the newly designed wrestling shoes was found to be highly positive and in a linear direction. Also, it was determined that the pain score values of the control group were higher than the scores of the experimental group after training. Conclusions The results revealed that there were deformations in the feet of the control group wrestlers wearing available wrestling shoes. It was observed that freestyle wrestling athletes had more deformation than Greco-Roman style wrestlers, and leg pains were more prevalent after training and competitions. Based on these results, it was concluded that the design of wrestling shoes produced with today's technology needs to be redesigned.Öğe Postural Control of The Elite Deaf Football Players(2015) Atalay Güzel, Nevin; Çınar Medeni, Özge; Acak, Mahmut; Savaş, SeyfiObjectives: Childhood hearing impairment is a common chronic condition that may have a major impact on postural control. The aim of this study was to determine the postural control of the elite deaf football players and compare normal-hearing football players and sedentary deaf controls. Eighteen deaf football players, ten deaf sedentary controls, ten normal-hearing sedentary controls were included in study. Methods: Postural stability was assessed both on bilateral stance and on single-limb stance with Biodex-Balance System on static surface, in eyes-open condition. Limits of stability testing were performed on bilateral stance. Results: Statistically significant results were found in medial-lateral index (MLI) score of dominant and non-dominant legs among three groups respectively (p=0.027, p=0.045). In limits of stability testing significant differences were found for overall direction (p=0.008) and right direction (p=0.017) among three groups. There was a significant difference in MLI score of non-dominant leg (p=0.012) and in right direction of limits of stability test (p=0.016) between deaf athletes and deaf controls. Also there were significant differences found in MLI score of dominant legs (p=0.023) and overall (p<0.001) and right (p=0.008) direction of limits of stability test between deaf controls and healthy controlsÖğe Prevelance of flatfoot in secondary school students and its relationship with obesity(2020) Korkmaz, Mehmet Fatih; Acak, Mahmut; Duz, Serkan; Bozduman, ÖmerAbstract: The aim of this study is to determine the flatfoot prevalence of secondary school students and to investigate the relationship between obesity. As the population of the study consists of 28540 students between the ages of 10 and 18 living in Yeşilyurt and Battalgazi districts of Malatya province, the sample consisted of 3493 people, 1593 women and 1903 men. It was found that, 16.7% of women (9.8% flexible, 6.9% rigid), 16.1% of men (9.3% flexible, 6.8% rigid) had pes planus. It was determined that 19.6% of the participants had problems in their feet and 9.7% of them had flexible, 6.9% had rigid pes planus and 3% had high arch. It was observed that 31.2% of overweight participants were flexible and 15.6% were rigid pes planus while 21.2% of the obese participants were flexible and 37.7% were rigid pes planus. The mean of visual analogue scale (VAS) scores in which the participants evaluated the pain in the lower part of the leg during the day was 6.0±.08, in students with flexible pes planus and 8.5±1.11 in students with rigid pes planus. As a result of the study, no significant relationship was found between gender and flatfoot, but there was a significant relationship between flatfoot and obesity in all age groups.Öğe Self-esteem levels among hearing Impaired athletes participating in the European Futsal championship(Sila Science, 2012) Acak, MahmutThis study examined the self-esteem levels of hearing impaired sportsmen living in different European countries according to certain variables. Data were collected form 103 male and 32 female athletes with at least 55 db hearing loss in both ears, who participated in 3rd European Deaf Futsal Championship, held in Switzerland. The ages of the athletes participating in the study ranged between 18 and 39 (average 24.49 years). The 10-item short form of the scale developed by Rosenberg was used to determine the self-esteem levels of the participants. A statistically significant difference was found in self-esteem levels according to gender, with higher self-esteem levels among hearing impaired males ((x) over bar = 1.20) than females ((x) over bar = 2.12). Self-esteem levels also varied significantly according to educational status, with higher self-esteem among hearing impaired university graduates than high school and secondary school graduates ((x) over bar = 0.82). More academic studies should be conducted to meet the expectations of hearing impaired people in every field and in order to create a highly-qualified and ideal impaired people, and so the availability of activities should be increased. Academic studies of other hearing athletes are important in terms of examining the impacts of the topic.
