Farklı Zeminlerde Oynanan Profesyonel Tenis Maçlarında Yaşın, Cinsiyetin Ve Boy Uzunluğunun Kat Edilen Mesafe Üzerindeki Etkileri
(2020) Dağdelen, Sina; Söğüt, Mustafa
Bu araştırmanın amaçlarını farklı zeminlerde oynanan profesyonel tenis maçlarında yaşın, cinsiyetin ve boy uzunluğunun maç süresince kat edilen toplam mesafe (TM), ortalama puan mesafesi (OPM) ve ortalama set mesafesi (OSM) üzerindeki etkilerini incelemek ve mesafe değişkenleri ile yaş ve boy uzunluğu arasındaki ilişkilerin incelenmesi oluşturmuştur. Araştırmaya 2018 yılında düzenlenen Wimbledon ve US Open tenis turnuvalarında ana tablo fikstürlerinde yer alan ve turnuvaların resmi internet adreslerinde antropometrik özellikler ile mesafe değişkenlerine ait verileri bulunan profesyonel erkek (n= 84) ve kadın (n= 94) oyuncular dahil edilmiştir. Araştırma bulguları hem erkek hem de kadın oyuncularda mesafe değişkenlerinde yaşa göre istatistiksel olarak anlamlı bir farklılık olmadığını göstermiştir. Göreceli olarak uzun boylu kadın oyuncuların hem çim hem de beton zeminde, OSM ve OPM değişkenlerde kısa boylu oyunculara göre daha az mesafe kat ettikleri bulunmuştur. Diğer yandan, sonuçlar, OPM değişkeninde cinsiyete göre istatistiksel olarak anlamlı bir farklılık olmadığını, OSM değişkeninde ise kadın oyuncuların istatistiksel olarak daha fazla mesafe kat ettiklerini göstermiştir. Korelasyon analizleri, her iki zemininde de mesafe değişkenleri ile yaş arasında istatistiksel olarak anlamlı bir ilişki olmadığını göstermiştir. Bununla birlikte, erkek oyuncularda beton zeminde ve kadın oyuncularda çim zeminde OSM ve OPM ile boy uzunluğu arasında istatistiksel olarak anlamlı ve negatif yönde bir ilişki bulunmuştur. Sonuç olarak, bu araştırma çim ve beton zeminlerde oynanan profesyonel tenis maçlarında kat edilen mesafe değişkenlerinin cinsiyet ve boy uzunluğuna göre değişim gösterdiğini vurgulamıştır.

(2019) Cengizhan, Pelin Aksen; Cobanoglu, Gamze; Gökdoğan, Çagatay Müslüm; Zorlular, Ali; Akaras, Esedullah; Örer, Gamze Erikoğlu; Kafa, Nihan
Aim: The purpose of this study was to identify relationships between postural stability, core muscle endurance and agility in basketball players. Materials and Methods: 21 professional male basketball players [age: 17.±0.63 (years), body weight: 78.69±9.22 (kg), height: 186±7 (cm), BMI: 22.72±2.26 (kg/cm²)] were included to this study. Three balance variables were measured using Biodex Biosway™. Core muscle endurance was measured using three core endurance tests proposed by Mcgill. Agility was assessed by Hexagonal Obstacle Test (HOT). Results: The analysis results showed that postural stability is associated with HOT (r: 0.457). In addition, the postural stability was related to extension muscle endurance test and side bridge test (respectively, r: -0.501 and r: -0.468). There is no correlation between HOT and core muscle endurance test in basketball players. Conclusion: The athletes with good postural stability were better core muscle endurance and agility. It is important to apply exercise programs that enhance postural stability and increase core muscle endurance to improve sportive success.

(GDANSK UNIV PHYSICAL EDUCATION & SPORT, 2020) Ari, Erdal; Deliceoglu, Gokhan
Background: Maturation is an important factor for exercise. The maturation effect on some anthropometric and motoric characteristics of students aged eight years was examined in this study. Material and methods: 535 primary education students voluntarily participated in this study. Anthropometric measurements (weight, height, sitting height, stroke length, stroke rate, leg length and body mass index), flexibility, handgrip strength, vertical jump (squat and countermovement jump), tapping (skipping) test paramaters (step frequency, flight times and contact times to ground of right and left foot, step/speed ratio), postural sway (anterior-posterior, medial lateral and total postural sway), visual reaction and reaction time, 20 meters sprint time, agility values were measured. The test parameters were compared in terms of gender and maturation level (early, normal and delayed maturation) by parametric (independent samples T-test, one way ANOVA) and non-parametric (Mann Whitney-U and Kruskal Wallis-H) tests. Results: A significant difference was indicated between boy and girl students in most of the test parameters (p < 0.05). The analysis results indicated that students at early maturation level had better test values (p < 0.05). Conclusions: The maturation factor positively affected some anthropometric and motoric parameters of students aged eight years.

(MATTIOLI 1885, 2020) Ersoy, Buse; Bilge, Murat; Caglar, Emine; Michalsik, Lars Bojsen
Study Objectives: The purpose of this study was to examine the impact of functional sprint training on the movement components affecting speed in youth basketball players. Methods: The subjects in this study consisted of three groups; a research group (RG(,age) = 12,5 +/- 0,3, n = 16), a basketball group (BG(,age) = 12,5 +/- 0,3, n = 16), and a control group (CG(,age) = 12,2 +/- 0,4, n = 16). In addition to normal basketball training RG performed functional sprint training known as A-B-C training while. BG performed only basketball training. CG did not perform any kind of training. The subjects in the RG and BG carried out a total of 24 training sessions during in eight-week period with 3 times x 45 min's training per week. All three groups were tested before and after the functional sprint training intervention using a group of well-known agility and sprint tests (Illinois, T-drill, 505 agility test, and a 20-m acceleration test). Results: Differences were found between BG and CG in the percentage of developmental values in 10-20 m (p < 0.05) in favor of BG, between RG and both BG and CG in the T-drill and Illinois agility test percentage of developmental values (p < 0.01) in favor of RG and between CG and both RG and BG in the 505 agility test percentage of developmental values (p < 0.05) against CG. Conclusion: The present findings show that 8 weeks of functional sprint training performed 3 times x 45 min per week had a marked effect on some movement components influencing speed ability in youth basketball players.
The roles of some agility performance parameters on the linear, single sprint skills of young male basketball and handball players
(MATTIOLI 1885, 2020) Bilge, Murat; Çağlar, Emine; Saavedra, Jose M.
Study Objectives: This study aimed to examine the roles of some agility parameters on the linear, single sprint skills among young male basketball and handball players. Methods: The participants in this study were male basketball players (BP) (n = 15, +/- SD= 15.30 +/- 0.48) and handball players (HP) (n = 32, +/- SD = 16.81 +/- 1.63) who trained regularly, and a control group (CG) (n = 31, +/- SD = 15.87 +/- 0.80). They participated in 0 to 30 m linear speed tests, a T test, a 505 agility test, and an Illinois agility test. Changes in direction, side stepping, reversing direction, and running backward were the main sub-parameters of agility performance that constituted the independent variables. A multiple regression analysis was conducted if these independent variables predicted the 0 to10 m, 10 to 30 m, and 0 to 30 m sprint performances separately. One way ANOVA was performed to determine group differences in all the independent variables. Results: The ANOVA revealed statistically significant differences between groups for the independent variables (p < 0.001). The Tukey HSD test indicated that all three groups significantly differed from each other. Conclusion: As a result, it can be concluded that agility parameters contributed to speed skills. It is recommended that the exercises that include agility parameters should be used when designing training, especially in team sports.

(MATTIOLI 1885, 2020) Yalcinkaya, Nehir; Cetin, Onat; Beyleroglu, Malik; Isik, Ozkan; Eker, Salih; Bilge, Murat
Study Objectives: The aim of this study was to investigate the effect of an alkaline diet with step aerobic exercises for 8-week in sedentary women on their body composition and aerobic exercise performances. Methods: 22 sedentary women (age = 49.18 +/- 6.28) voluntarily participated in the study (n = 11 alkaline diet group; n = 11 acidic diet group). Alkaline diet and acidic diet programs were applied to the sedentary women together with step aerobic exercises for 8 weeks. This research was designed as a randomized controlled trial model. Body composition (total body weight, fat mass, and free-fat mass), aerobic exercise performance indicators (Bruce treadmill test, lactate accumulation, estimated VO2Max, and rating of perceived exertion) were measured before and after diet and exercise programs. Results: The results of the body weight, fat mass, lactate accumulation, and rating of perceived exertion levels of the group consuming an alkaline diet together with the eight-week step aerobic exercises showed a higher decrease and aerobic exercise performance duration and VO2Max levels indicated a higher increase than acidic diet group. Conclusion: The alkaline diet with reduced acid value together with 8-week step aerobic exercises in sedentary women, has a high rate of positive effects on body composition and aerobic exercise performances.
Total Dietary Antioxidant Intake Including Polyphenol Content: Is It Capable to Fight against Increased Oxidants within the Body of Ultra-Endurance Athletes?
(MDPI, 2020) Devrim-Lanpir, Asli; Bilgic, Pelin; Kocahan, Tugba; Deliceoglu, Gokhan; Rosemann, Thomas; Knechtle, Beat
The role of dietary antioxidants on exhaustive exercise-induced oxidative stress has been well investigated. However, the contribution of total dietary antioxidant capacity on exogenous antioxidant defense and exercise performance has commonly been disregarded. The aims of the present investigation were to examine (i) the effects of dietary total antioxidant intake on body antioxidant mechanisms, and (ii) an exhaustive exercise-induced oxidative damage in ultra-endurance athletes. The study included 24 ultra-marathon runners and long-distance triathletes (12 male and 12 female) who underwent an acute exhaustive exercise test (a cycle ergometer (45 min at 65% VO(2)max) immediately followed by a treadmill test (75% VO(2)max to exhaustion). Oxidative stress-related biomarkers (8-isoprostaglandin F2alpha (8-iso PGF2a), total oxidant status (TOS, total antioxidant status (TAS)) in plasma were collected before and after exercise. Oxidative stress index was calculated to assess the aspect of redox balance. Blood lactate concentrations and heart rate were measured at the 3rd and 6th min after exercise. Dietary antioxidant intake was calculated using the ferric reducing ability of plasma (FRAP) assay. Dietary total antioxidant intake of the subjects was negatively correlated with pre-exercise TOS concentrations (rs = -0.641 in male, and rs = -0.741 in females) and post- vs. pre- ( increment ) 8-iso PGF2a levels (rs = -0.702 in male;p= 0.016, and rs = -0.682 in females;p= 0.024), and positively correlated with increment TAS concentrations (rs = 0.893 in males;p= 0.001, and rs = 0.769 in females;p= 0.002) and post- exercise lactate concentrations (rs = 0.795 for males;p= 0.006, and rs = 0.642 for females;p= 0.024). A positive meaningful (p= 0.013) interaction was observed between time at exhaustion and dietary antioxidant intake (rs = 0.692) in males, but not in females. In conclusion, the determination of total dietary antioxidant intake in ultra-endurance athletes may be crucial for gaining a better perspective on body antioxidant defense against exhaustive exercise-induced oxidative stress. However, the effects of dietary antioxidant on exercise performance and recovery rate needs further investigation.

Study Objectives: The objective of this study was to examine the effect of three weeks of dry-land training on functional strength and swimming performance in addition to eight weeks of swimming training of 15 female athletes in the 10-12 years age group with at least three years of training history. A total of 30 athletes between the ages of 10-12 participated in the study; it was divided into control and experimental groups. Methods: Muscle strength tests and swimming performance tests (50 In freestyle, 400 m freestyle, critical swimming speed tests) were applied to all groups before and after the test at eight week intervals. 'The dry-land training program applied to the experimental group was prepared for the 10 most frequently used muscle groups in swimming branch in the literature. Descriptive statistics were applied to the obtained data. The normality of data were analyzed with Kolmogorov-Smirnov test and it was found that the data showed a normal distribution. Paired samples t test was used for within group comparisons in the analysis of data and independent samples t test was used for comparison of measurement times of the groups. Results: Trapezius middle left-right deltoid anterior left-right, deltoid middle-right, triceps brachii left-right, gluteus maximus left-right, tensor facia latasol-right, biceps femoris left-right, quadriceps femoris left-right; a statistically significant difference was found between the groups in terms of 400 m free style and 50 m free style critical swimming speed variability (p <0.05). When the pre-test and post-test values of the experimental group were compared, Trapezius middle left, deltoid anterior left-right, biceps brachii left-right, brachio radialis left-right, gluteus maximus left-right, tensor fasia lata left-right, biceps femoris left-right, quadriceps femoris left-right statistically significant differences were found in 400 m free style, 50 m free style critical swimming speed variables (p <0.01). When the developmental values of the experimental and control groups were examined, trapezius middle-left, deltoid anterior left-right, deltoid middle-left, biceps brachii left-right, brachio radialis left-right, gluteus maximus left-right, tensor facia lata left, biceps phemoris left-right, quadriceps femoris left-right; statistically significant differences were found in 400 m free style and 50 m free style critical swimming speed variables (p <0.05). Conclusion: Dry-land training has a positive effect on swimming and functional strength performance in 10-12 years old strength swimmers.
Skeletal muscle fatigue does not affect shooting accuracy of handball players
(Ios Press, 2019) Akyuz, Beyza; Avsar, Pinar Arpinar; Bilge, Murat; Deliceoglu, Gokhan; Korkusuz, Feza
BACKGROUND: Shooting accuracy and ball speed are important factors relating to scoring in handball that could be affected by skeletal muscle fatigue. OBJECTIVE: To explore the effects of muscle fatigue on male handball players' shooting accuracy and ball speed. METHODS: Sixteen elite handball players (M-age = 17.1 +/- 1.7 years) participated in the laboratory and the field-testing sessions. Running speeds equal to 75% of participants' maximal oxygen uptake (VO2max) values from laboratory tests were used as the initial velocity for the 30-15 intermittent fitness test (30-15(IFT)) in the fatigue protocol. Participants shot to the target at random visual signals placed behind the target before and after fatigue. In order to measure wrist acceleration and ball speed, an accelerometer and a radar gun are used respectively and numbers of accurate and inaccurate shots also recorded. RESULTS: There were no significant differences between pre-fatigue and post-fatigue protocols in terms of accurate and inaccurate shots, and ball speed. Only wrist acceleration in the Y axis (M-pre(-fatigue) = 33.12, SD = 1.17msec; M-post - fatigue = 34.50, SD = 1.21msec) was affected by the fatigue protocol in inaccurate shots (p = 0.042). CONCLUSIONS: Muscular fatigue does not affect shooting accuracy and ball speed in male handball players.
Is there any predictive equation to determine resting metabolic rate in ultra-endurance athletes?
(Mattioli 1885, 2019) Devrim-Lanpir, Asli; Kocahan, Tugba; Deliceoglu, Gokhan; Tortu, Erkan; Bilgic, Pelin
Background/aims: Only a few studies determined some equations to predict resting metabolic rate (RMR) in endurance athletes, however the validity in ultra-endurance athletes, such as triathletes and ultra-marathoners, had not been examined previously. The aim of this study was to assess the accuracy of commonly used RMR predictive equations (Harris-Benedict, Mifflin-St. Jeor, Cunningham, WHO/FAO/UNU (calculated by using body mass and height and body mass alone), Wang, and Sabounchi (Structure 4, 5, and 11) equations) comparing with measured RMR in ultra-endurance athletes. Methods: Male (n=15) and female (n=15) ultra-endurance athletes age 23 to 55 years from Ankyra Sports Club were included. The Bland-Altman plot was performed to determine mean bias and limits of agreement between measured and predicted RMRs. Linear regression analysis was used to determine the accuracy of each predictive equation by computing the standard en-or of estimate and root-mean-squared prediction error (RMSPE). Results: Mifflin-St. Jeor equation was found to be the best predictive equation with lowest RMSPE (275.85 kcal/day for men and 388.34 kcal/day for women) and mean difference (3.04 +/- 285.51 kcal/day for men and 185.57 +/- 353.10 for women) in ultra-endurance athletes. The Cunningham equation could be used in estimating RMR in male athletes (RMSPE, 310.77 kcal/day, the bias between measured vs. predicted RMR, 147.68 +/- 283.04 kcal/day). Conclusions: The Mifflin- St. Jeor and Cunningham equations for men and the Mifflin-St. Jeor equation in women could be used with caution in the absence of indirect calorimetry in ultra-endurance athletes. All other predictions significantly underestimated RMR for both sexes.
Stature: Does it really make a difference in match-play outcomes among professional tennis players?
(Routledge Journals, Taylor & Francis Ltd, 2018) Sogut, Mustafa
The purpose of this study was to determine the effects of body height on match-play characteristics among professional tennis players participated in the 2017 Wimbledon Championships. Anthropometric features and 11 match-play statistics of 119 players (male=60, female=59) were obtained from the official web page of the tournament and/or from the ATP and WTA. They were divided into three consecutive sub-groups according to their heights. Results revealed that, regardless of gender, players in the tallest group had significantly produced higher speed on both first and second serve than the players in the other groups. Tallest male players exhibited significantly greater scores on the percentage of first serve points won and aces per set than the players in the shortest group. Conversely, players in the shortest groups achieved significantly more percentage of return point than the players in the tallest groups. Height was found to be significantly and positively correlated with both first and second serve speeds, and aces performed per set and significantly and negatively associated with percentage of return points won in both genders. These findings highlight the considerable advantages and disadvantages of stature on serve and return related match outcomes in a grass court tournament.
A comparison between core exercises with Theraband and Swiss Ball in terms of core stabilization and balance performance
(Ios Press, 2018) Aksen-Cengizhan, Pelin; Onay, Derya; Sever, Ozan; Dogan, Ali Ahmet
BACKGROUND: Core exercises include exercises to train muscles that control and stabilize the movements of the abdomen, waist, and hip. Thanks to these exercises, the control and balance of the body are increased. Exercises on unstable surfaces increase the level of muscle activity, and by using elastic resistance tools, one or more joints can be simultaneously and efficiently trained. OBJECTIVE: To compare core exercises with Theraband and Swiss Ball in terms of core stabilization and balance performance. METHOD: A total of 22 women who perform recreational sports between 25 and 46 years of age participated in the study. The participants were separated into two groups: Swiss Ball (SBC, n = 11) and Theraband (TBC, n = 11). Both groups were subjected to core exercise programs for 6 weeks, 3 days a week, around 40 minutes per day. Prior to and after the 6-week exercises, body composition, core stabilization, Star Excursion Balance Test (SEBT), and Stork balance test scores were compared. RESULTS: No difference was found between groups in terms of pre-test values. While the weight and body mass index values decreased in all groups, the balance and core stabilization test scores increased significantly. With the exception of the SEBT, which has increased significantly in the TBC group, there were no differences between the groups in none of the scores. CONCLUSION: As both training methods lead to positive effect on the tested variables, the choice of the specific method should probably be decided based on individual preference and the training environment.
Screen Time Differences among Turkish University Students as an Indicator of Sedentary Lifestyle and Inactivity
(Fac Teacher Education, 2017) Caglar, Emine; Bilgili, Naile; Karaca, Ayda; Deliceoglu, Gokhan
The aim of the present study was to examine the screen time differences as an indicator of sedentary lifestyle in terms of some socio-demographic variables among university students. A total of 2209 university student (M-age = 20.80, SD = 1.61 years) participated in this study. The demographic information and screen time data were collected by using a survey form. The screen time refers to the combined time spent on watching TV/video, watching/playing/working on a computer, and playing video games. Two x three factorial ANOVA revealed significant gender and socioeconomic status differences in the screen time. The male students and those with a high socio-economic status had higher screen time. In addition, one-way ANOVA showed significant screen time differences in terms of parental education level and place of residence (p < .001). The students living in dormitories and those whose parents had lower education level had lower screen time. Also, the students who had an opportunity to access technological devices in their place of residence and in their bedrooms had higher screen time than the students who did not have these facilities (p<.001). The screen time as a sedentary behavior among university students is quite high and these findings can be taken into account as a warning indicating increases in the sedentary lifestyle of these young adults.

(Montenegrin Sports Acad, 2015) Gunay, Mehmet; Cengizhan, Pelin Aksen; Ozsari, Mehmet
This study was carried out with the aim of determining the PA levels of the trainers working in Kastamonu in terms of gender and marital status variables. This study was applied to trainers from 15 different branches in the competitions organized by Kastamonu Directorate of Youth and Sports and Kastamonu Directorate of National Education. A total of 51 trainers participated in the study voluntarily; 19 of them were female; their mean age was 26.53 +/- 9.08 years, their mean height was 167.37 +/- 5.37 m and their mean weight was 60.37 +/- 7.30 kg. 32 of the trainers were male; their mean age was 35.41 +/- 8.10, their mean height was 179.69 +/- 6.25 m and their mean weight was 83.94 +/- 12.11 kg. Since the PA levels of the trainers working in the city center of Kastamonu were studied, the number of subjects was 51. In this study, in order to determine the physical activity level of the trainers, Physical Activity Evaluation Survey (PAAQ) has been used. SPSS 15.0 was used to analyze the data in the dual comparisons, the nonparametric Mann-Whitney U Test has been applied. According to gender, there was no significant difference in met/week values of all indexes (p>0.05); also according to marital status, there was significant difference in met/week value of work index (p<0.05, U=183,500). As a result, according to gender, while it was found that PA levels of male trainers were higher in work (p>0.05, U=230,500) and sport indexes (p>0.05, U= 282,000), PA levels of female trainers were found higher in home index. On the other hand, it was also determined that according to marital status, PA levels of single trainers were higher than married trainers in work index.
A study of the effects of explosive strength exercises on some blood parameters, technical and conditional characteristics of female basketball players in the 15-17 age group
(Edizioni Minerva Medica, 2015) Cengizhan, P. Aksen
Aim. This study analyzed the effects of explosive strength exercises on some blood parameters, technical and conditional characteristics of female basketball players aged 15-17 years. Methods. A total of 20 female basketball players volunteered to participate in a 6-week physical training program. Two groups were formed: the training group (N.=10, age 14.80 +/- 1.14 years, height 161.20 +/- 5.07 cm, weight 54.30 +/- 8.64 kg) performed explosive strength exercises in addition to technical exercises, while control group (N.=10, age 14.90 +/- 0.99 years, height 164.60 +/- 7.77 cm, weight 59.70 +/- 15.83 kg) performed only technical exercises. Venous blood samples (5 mL) for blood parameter analysis were taken from both groups before the beginning of the training program and then after motor and technical tests at completion of the program. The data of both groups prior to and after exercise were compared with the Wilcoxon test and the intergroup comparisons performed with the chi-square test. Data were analyzed with the SPSS 19.0 package program. A P value of 0.05 was considered significant. Results. Comparison of blood profiles and motor and technical test values before and after completion of the exercise program showed statistically significant differences in body weight and systolic blood pressure, reaction time of left hand to light, agility, right and left hand grip strength, leg and back strength, flexibility, 10 x 5 m, 20 m and 30 m sprint time, cholesterol, iron-binding capacity and sodium, urea, creatinine, gamma-glutamyltransferase (GGT), uric acid and albumin, lactate dehydrogenase (LDH), and creatine kinase (CK) values. Conclusion. Explosive strength exercises performed for 6 weeks have a positive impact on motor characteristics such as leg, back and grip strength, agility, speed and continuity in speed, in addition to certain blood parameters such as iron-binding capacity, sodium, urea, CK, GGT, uric acid, and albumin. Physical exercises and strength training decrease the levels of CK and LDH, two enzymes with a role in determining skeletal muscle damage. Explosive strength exercises improve muscle tolerance to damage.

(Acad Physical Education-Katowice, 2012) Bilge, Murat
The development of men's handball was analyzed using data from the Olympic, World and European Championships held within the last eight years. The most obvious change, especially within these last nine tournaments, was that men's handball was played more dynamically and rapidly, both in attack and defense, especially by European teams. The first aim of this study was to conduct a technical analysis of current handball and to determine factors related to success in this sport discipline. The second aim was to compare the data of European Championships with other tournaments, considering the success of European teams in Men's World Handball. The technical variables used to compare the tournaments included: the average number of attacks, the efficiency of attacks, the efficiency of goal throws, fast break goals per game, the efficiency of fast breaks, the efficiency Of the goalkeeper, saves by the goalkeeper per game, number of turnovers per game, and the efficiency of position throws (wing, pivot, back court, break-through, fast break, and 7-meter). This technical analysis used cumulative statistics from the European Handball Federation and International Handball Federation. ANOVA revealed significant differences between the first eight teams in the European Championships and their counterparts in the other two tournaments (Olympics and World Championships) in terms of several technical variables. The results showed that the efficiency of fast break, pivot position and back court players affected the ranking in favor of the European teams in significant international tournaments.

This study aims to determine the rates of injuries, the types of injuries and what part of the body is mostly injured in professional taekwondo sportsmen during competitions. This study involves 287 sportsmen participated in the interuniversity Taekwando championship in Ordu. Injuries during a match of the championship was determined by a team. The characteristics and types of injuries, the sportsmen’s verbal expressions were registered by a pre-determined team, and it was mentioned about how these injuries occurred, in which part of the body the injuries were seen. Among 287 sportsmen in this study, 178 sportsmen were male, 109 ones were female. 46 universities took part in this championship. The championship lasted three days and total 271 competitions were done. 539 injuries were determined in total. The mostly seen type of injury was hematoma (43%), the mostly injured part was in lower extremities 416 (77%), most of the injuries were ones seen in defense (36%). No injuries were not observed in neck, shoulder, spine or trunk and cerebral injuries were not also observed. As a result of the study, it was explained that most of the injuries seen in the taekwondo competitions did not require the medical intervention and the lower extremities were mostly injured in these competitions. In the light of these findings, it could be said that these parts be protected during the competitions and the defense techniques be different.

Amaç: Elit erkek plaj voleybolu ile salon voleybolu sporcularının sıçrama performansı ve diz eklemikas kuvvetinin karşılaştırılmasıdır. Gereç ve Yöntemler: Çalışma 6 erkek plaj voleybolu sporcusu, 6 erkeksalon voleybolu sporcusu ve kontrol grubunda 6 erkek sedanter birey olmak üzere toplam 18 katılımcı ilegerçekleştirildi. Katılımcıların sıçrama performansları opto jump test cihaz kullanılarak, kas kuvvetleri Iso-Med 2000 cihazı kullanılarak değerlendirildi. Grupların sıçrama performansları ve diz eklemi fleksör veekstansör kas kuvveti arasındaki farklılıkları belirlemek için Kruskall Wallis testi uygulandı. Gruplar arasındakifarklılığın hangi gruplardan kaynaklandığını belirlemek amacıyla Mann-Whitney U testi uygulandı.Anlamlılık düzeyi p0,05 olarak alındı. Bulgular: Grupların skuat, aktif ve serbest sıçrama değerleri arasındaistatistiksel olarak anlamlı farklılık olduğu ve plaj voleybolu sporcularının sıçrama mesafelerinin en fazla olduğubelirlendi (p0,05). 60/sn açısal hızda salon voleybolu sporcularının diz eklemi ekstansör kaslarının izokinetikkas kuvvetinin daha fazla olduğu saptandı (p0,05). 60/sn açısal hızda diz eklemi fleksör kas kuvvetininise plaj voleybolu sporcularında daha fazla olduğu bulundu (p0,05). 60 ve 180/sn açısal hızda hamstring/quadricepskas kuvvet oranlarının gruplar arasında farklı olduğu, kontrol grubundaki bireylerin kas kuvvet oranınınen fazla, salon voleybolu grubunda ise en az olduğu belirlendi (p0,05). Sonuç: Plaj voleybolu sporcularınınsıçrama performansı ve diz eklemi fleksör kaslarının kas kuvvetinin daha fazla olduğu ve diz eklemi ekstansörlerialeyhinde kuvvet dengesizliği olduğu; salon voleybolu sporcularının diz eklemi ekstansör kas kuvvetinindaha fazla olduğu ve diz eklemi fleksörleri aleyhinde kuvvet dengesizliği olduğu saptandı. Voleybolsporcularında sıçrama performansı ve diz eklemi fleksör kas kuvvetini artırmak için kumda; diz eklemi ekstansörkas kuvvetini artırmak için ise terafleks gibi sert zemin üzerinde antrenman yapılması önerilmektedir.
Tabancalı Atıcılık Sporcularında Ayak Basış Genişliği, Postural Salınım, Üst Ekstremite İzometrik Kas Kuvveti ve Atış Performansı Arasındaki İlişkinin İncelenmesi
(2019) Kocahan, Tuğba; Akınoğlu, Bihter; Genç, Abdullah; Kabak, Banu; Deliceoğlu, Gökhan; Hasanoğlu, Adnan
Amaç: Tabancalı atıcılık sporcularında ayak genişliği, postural salınım, üst ekstremite izometrikkas kuvveti ve atış performansı arasındaki ilişkinin incelenmesidir. Gereç ve Yöntemler: Araştırmanınörneklem grubunu 12 tabancalı atıcılık milli takım sporcusu oluşturdu. Sporcuların atış anındaki postural salınımları Kistler marka Body Sway Modülü ile izometrik kas kuvveti IsoMed 2000 izokinetikkas kuvvet ölçüm cihazı ile değerlendirildi. Atış performansları, 2017-2018 yılları arasında atıcılık resmimüsabaka sonuçlarının ortalamaları alınarak değerlendirildi. Veriler arasındaki ilişki Spearman korelasyon analizi ile incelendi. Bulgular: Omuz abdüktör kaslarının izometrik kas kuvveti ile atış performansı arasında anlamlı ve orta düzey bir ilişki olduğu belirlendi. Omuz addüktör kaslarının izometrikkas kuvveti ile atış performansı arasında anlamlı bir ilişki olmadığı saptandı. Sporcuların alışılmış ayakaçıklığı ile total salınım hızı, anterior-posterior salınım hızı ve total salınım alanı arasında anlamlı veyüksek düzeyde bir ilişki olduğu bulundu. Aynı zamanda, alışılmış ayak açıklığı ile medio-lateral salınım alanı arasında anlamlı ve orta düzey bir ilişki olduğu belirlendi. Omuz genişliğinin ½ ve ¾ ayakaçıklıkları ile postural salınım arasında anlamlı bir ilişki olmadığı görüldü. Sonuç: Bu çalışma, ulusal veuluslararası düzeyde spor yapan tabancalı atıcılık sporcularında omuz abdüktör kaslarının izometrikkas kuvvetinin atış performansını etkilediği, alışılmış ayak açıklığı ile salınım hızı arasında ilişki olduğu ve alışılmış ayak açıklığı sınırları dışındaki ayak açıklıklarının ise postural salınım ve salınım hızıüzerinde etkisi olmadığını göstermiştir. Bu bağlamda atıcılık sporcularında alışılmış ayak açıklığında yapılacak omuz abdüktör kaslarına yönelik kuvvet egzersizlerinin atış performansını iyileştirebileceğidüşünülmektedir.
