Öğe An Examination of Volunteer Motivation Among Individuals Participating in Sports Events Across Different Disciplines(Bayburt University, 2025) Güzel, Sema; Yaman, M. Sibel; Yel, Kader; Çakır, Zekai; Gönen, Mevlüt; Ceyhan, Mehmet Ali; Aydemir, BurakhanThe purpose of this study is to determine the motivation levels of volunteers involved in sports events and to examine whether these levels differ according to selected demographic and sport-related variables. Volunteer motivation is addressed as a multidimensional construct encompassing individual interests, goal orientation, and social solidarity. Designed as a descriptive study based on the relational survey model, the research was conducted with 399 volunteers actively engaged in various individual and team sports. Data were collected using Google Forms, which included the Sports Events Volunteer Motivation Scale (SEVMS) and a demographic information form developed by the researcher. The internal consistency coefficient of the scale for the present sample was calculated to be 0.810. Data analysis included independent samples t-tests, one-way analysis of variance (ANOVA), and Pearson correlation analysis. The findings indicate that volunteer motivation exhibits a multidimensional structure. The total motivation score was found to be strongly associated with the purposive and solidarity dimensions of motivation. Statistically significant differences were identified in total motivation and several sub-dimensions according to gender, active participation in sports, type of sport, income level, and age. Higher motivation levels were observed among individuals who actively engage in sports, participate in team sports, belong to higher-income groups, and are aged 27 years or older. Nevertheless, the effect sizes were predominantly small to small-to-moderate, suggesting that these variables exert a statistically significant yet limited influence on volunteer motivation. In conclusion, sports volunteering appears to be shaped by both individual and social–communal components, underscoring its inherently multidimensional nature. Accordingly, volunteer management practices in sports organisations should be supported by flexible and inclusive programs that are responsive to diverse motivational profiles..Öğe Çeşitli antrenman metotlarının taekwondocularda bazı biyomotor ve fizyolojik özelliklere etkisi(Bayburt Üniversitesi, 2024) Aydemir, Burakhan; Kul, MuratBu çalışmanın amacı, çeşitli antrenman metotlarının taekwondocularda bazı biyomotor ve fizyolojik özelliklere etkisini incelemektir. Kontrol gruplu deneysel model kullanılarak yapılan bu çalışmada 3 farklı araştırma grubuyla uygulama yapılmıştır. Araştırma gruplarının tümü 2023 yılında aktif olarak taekwondo sporunda lisanslı sporcu olmakla birlikte Trabzon ilinde ikamet eden müsabık sporculardan oluşmaktadır. Katılımcıların yaş guruplarının belirlenmesi ise ulusal/uluslararası turnuvalarda en fazla sporcunun katılım sağladığı gençler kategorisinde (14-17 yaş) yarışmacı olmalarına dikkate alınmıştır. Bu gruplar Deney Grubu 1 (taekwondoya özgü pliometrik antrenman), Deney Grubu 2 (taekwondoya özgü direnç lastiği antrenmanı) ve Kontrol Grubu (taekwondo antrenmanı) olarak adlandırılarak rastgele atama yapılarak belirlenmiştir. İlgili gruplara uygulanan 8 haftalık antrenman döneminin öncesinden ve sonrasında 20 metre sürat testi, 5-10-5 çeviklik testi, dikey sıçrama testi, stork denge testi, rast test, yoyo testi, taekwondo tekme frekansı performansı ve taekwondo elektronik yelek vuruş testleri uygulanmıştır. Gruplardan elde edilen verilerin SPSS (25. sürüm) yazılımıyla tanımlayıcı analizlerinin yapılmasının ardından araştırmada yer alan pliometrik, direnç ve kontrol gruplarının biyomotor ve fizyolojik gelişimlerinin grup içi (ön test-son test) karşılaştırmalarında wilcoxon işaretli sıralar testi, grupların ön ve son testlerinin gruplararası karşılaştırmalarında ise kruskal wallis testi kullanılmıştır. Kruskal wallis testi sonucunun anlamlı çıktığı durumlarda farkın hangi gruplar arasında olduğunu belirlemek amacıyla posthoc çoklu karşılaştırma testlerinden düzeltilmiş bonferroni kullanılmıştır. Biyomotor test sonuçları incelendiğinde denge ve eseklik parametreleri taekwondoya özgü direnç lastği ile antrenman yapan grup lehine sonuçlar göstermiştir. Fizyolojik test sonuçları incelendiğinde, max güç, yorgunluk indeksi, relative güç ve maxVo2 parametreleri pliometrik antrenman yapan grup lehine sonuçlar geöstermiştir. Elektronik yelek vurş testi gruplar arası farklılıkların incelendiği sonuçlara göre ise palding ve yopchagi tekiklerinde direnç lastiği ile antrenman yapan grup lehine sonuçlar görülürken, burgu palding tekniği pliometrik antrenman yapan grubun lehine sonuçlar göstermiştir. Sonuç olarak; direk ve patlayıcı vuruşların yapıldığı teknikler için taekwondoya özgü direnç lastiği antrenmanlarının etkisi bulunurken, atletik ve dönerek yapılan daha zor vuruşlarda pliometrik antrenmanların etkisi bulunmuştur.

The study utilized two different training methods: plyometric exercises on sand and plyometric exercises on taekwondo mats, with a control group performing only regular taekwondo training. The study included 66 athletes, all with at least 5 years of taekwondo experience, from Trabzon, Turkey, in 2024. Participants were divided into two experimental groups: Group 1, performing plyometric exercises on sand, and Group 2, performing plyometric exercises on taekwondo mats. After an 8week training program, biomotor and technical performance tests were applied to all groups for comparison. The data were tested for normal distribution using the Kolmogorov-Smirnov test, and since the data did not show normal distribution, non-parametric tests were used for analysis. Wilcoxon tests were applied for within-group comparisons, while Kruskal-Wallis tests were used for between-group comparisons. In cases where significant differences were found, Post hoc multiple comparison tests with Bonferroni correction were used to identify which groups showed the differences. The results showed that all groups demonstrated significant improvements in biomotor and technical performance parameters after the training programs. Group 1, the sand-based plyometric training group, showed more pronounced improvements in speed, agility, jump, balance, and technical performance parameters. The findings suggest that sand-based plyometric training has a significant impact on sports requiring speed, power, endurance, and technical skills, such as taekwondo.Öğe Examination of the Relationship Between MaxVo2 Values and Various Parameters of Football Players Playing in Amateur Football Team(METİN YAMAN, 2024) Kul, Murat; Aydemir, BurakhanFootball has been a sport that has been followed with interest from past to present and has attracted the masses. The game of football, played within the framework of certain rules, has also become a large sector in terms of sports economy. It is stated that the highest level of performance and all physiological characteristics should be analyzed in the football branch, as it consists of various movement sequences and includes versatile skills. In the literature, performance is defined as the score obtained from physical, physiological and biomotor data. In this context, this study aims to examine the relationship between MaxVo2 values and Various Parameters of football players playing in an amateur football team. In the study where the relationship between MaxVo2 values of football players and various parameters was examined, the correlational method, one of the quantitative research methods, was used. The research group consists of football players playing for Ağasar Çepni Football Club in the Trabzon 1st Amateur Football League. Average age of participants; 26.06±4.56, average height; 175.17±5.74, body weight (kg); It consists of 18 volunteer football players whose age is 73.79±11.11. SPSS.22 program was used in the statistical analysis of the data. Descriptive analyzes of football players were calculated as mean and standard deviation. Relationships between variables were determined using the Pearson correlation test. The significance level was taken as pÖğe Investigation Of The Relationship Between Brief Resilience Levels Of Taekwondo Players And Their Levels Of State And Trait Anxiety(Hasan ŞAHAN, 2023) Aydemir, Burakhan; Kul, Murat; Kırkbir, FatihThe study aimed to examine the relationship between the psychological resilience levels of taekwondo players and their state and trait anxiety levels.Taekwondo is a martial art originating from the Far East. Taekwondo is a very popular sport in our country because it is an Olympic sport. In the literature, the contribution of Taekwondo sport to both physical and mental development is expressed. Normally, 3 rounds are played over 2 minutes, and the competition may conclude at the end of the 2nd round, provided that the athletes close the rounds with a 2-0 advantage. Athletes play an average of 6-8 competitions a day and experience a high physical and mental process until the end of the day. It is thought that the competition process may cause some psychological processes in athletes. In this process; Athletes are expected to experience some psychological processes such as anxiety, worry, fear and stress. The universe of the study consisted of 270 taekwondo athletes participating in the U-21 Taekwondo Turkey Championship. While 130 of the participants were male athletes, the remaining 140 were female participants. While 72 participants were national athletes, the age range of the total participants was found to be 16-20. The data were collected from the athletes through a questionnaire during the Turkish Taekwondo Championships. The athletes were informed before the weigh-in and they were asked to fill in the questionnaires on a voluntary basis. The completed questionnaires were collected from the athletes and stored. The socio-demographic information form for the demographic information of the athletes, the Brief Psychological Resilience Scale, and the STAI-I and STAI-II Anxiety Scales (Stated and Continuous) were used to collect the data. The analyses done in line with the options specified by the athletes were made in the SPSS 23.0 program. After the reverse items of the scales were translated, the scores obtained from the scales were summed. Then, the data were evaluated with Kolmogorov Smirnov analysis of normality. According to the results of the normality test, it was determined that the data showed normality. According to the demographic variables of the athletes, t-test was used in independent groups for paired groups and Tukey-corrected One Way Anova test was used for groups of more than two. Pearson correlation analysis was used to evaluate the relationship between the self-esteem mean score and the resilience scale mean score. The results were evaluated at the pÖğe Validity and Reliability of a Novel AI-Based System in Athletic Performance Assessment: The Case of DeepSport(Mdpi, 2025) Aydemir, Burakhan; Aydogan, Muhammed Talha; Boz, Emre; Kul, Murat; Kirkbir, Fatih; Ozkara, Abdullah BoraThis study aimed to examine the validity and reliability of the AI-based DeepSport application by comparing its outcomes with those from the reference device, OptoJump. The primary dependent variables measured were jump height and anaerobic power during vertical jump assessments. Twelve elite male basketball players voluntarily participated in the study (age = 21.53 +/- 1.14 years; sports experience = 6.47 +/- 1.01 years). DeepSport uses AI-based image processing from standard cameras, while OptoJump uses optical sensor technology. Both DeepSport and OptoJump systems were utilized to assess participants' Countermovement Jump (CMJ) and Squat Jump (SJ) performances. A G*Power (version 3.1.9.7) analysis determined the required sample size, adopting a 95% confidence level, 90% test power, and an effect size of 0.25. Validity assessments were conducted using Bland-Altman plots and ordinary least products (OLP) regression analysis, while reliability was evaluated through intraclass correlation coefficient (ICC), coefficient of variation (CV), standard error of measurement (SEM), and smallest detectable change (SDC) analyses. DeepSport showed excellent reliability in CMJ and SJ tests with ICC values > 0.90, and CV ranged between 2.12% and 4.95%. Results were consistent with OptoJump, showing no significant differences according to t-test results (p > 0.05). Bland-Altman analyses indicated no systematic bias and random distribution. These findings confirm that both DeepSport and OptoJump devices demonstrate high reliability and consistency, suggesting their validity and reliability for use in athlete performance assessments by coaches and athletes.
