This study was conducted to investigate the effect of core exercise program on vertical jump, speed, agility and strength parameters in junior male soccer players. In the study, pretest-posttest control group design, one of the experimental models of quantitative research method, was used. The experimental group of the study consisted of 12 male soccer players (X̄year: 12,16±,83) who underwent core exercise 3 days a week for six weeks in addition to regular soccer training, while the control group of the study consisted of 12 male athletes (X̄year: 12,25±,62) who underwent only regular soccer training. Leg strength, core strength, vertical jump, 30 m sprint and agility tests were administered to the athletes who voluntarily participated in the study before and after six weeks of training. The normality level of the data was determined by Shapiro-Wilk test. Independent Sample T Test for independent groups and Paired Sample T Test for dependent groups were used to analyze the normally distributed data. According to the findings of the study, there was a statistically significant difference between the pre-test - post-test measurement values of all performance tests of the experimental group and core strength, vertical jump, 30 m sprint and agility tests of the experimental and control groups (p0.05), while no significant difference was found in the control group (p0.05). According to the results of the study, it can be said that the core exercise program applied to male football players has positive effects on the development of vertical jump, speed, agility and strength parameters.Keywords: Core exercise, Football, Jumping, Speed, Strength

This study was conducted to determine the effect of four weeks of high intensity interval training on blood oxygen saturation, body composition and some performance parameters in young male football players. Pre-test-post-test control group experimental method was used in the study. Twelve experimental (age: 16,33,77 years; height: 171,50,6,23 cm; body weight: 58,33,5,19 kg) and 12 control (age: 16,50,52 years; height: 168,58,5,68 cm; body weight: 58,05,4,60 kg) male football players aged 15-17 years, who regularly exercise and have been playing football for at least 3 years participated in the study. In the study, the experimental group performed high intensity interval training 3 days a week in addition to football training for 4 weeks. The control group only performed routine football training. In the study, height and body weight, resting heart rate, systolic and diastolic blood pressure, blood oxygen saturation, body composition, 20 m sprint test, Illinois agility test and Yo-Yo interval running test were applied as pre and post tests. The normality level of the data was determined by Shapiro-Wilk test. Independent Sample T Test for independent groups and Paired Sample T Test for dependent groups were used to analyse the normally distributed data. According to the findings of the study, while statistical significance was determined in blood oxygen saturation, body composition, Illinois agility test and Yo-Yo interval running parameters of the experimental group (p0.05). According to the results of the study, it can be said that 4-week high intensity interval training has positive effects on blood oxygen saturation, body composition and performance parameters in young male football players.

The purpose of this study was to examine whether the addition of a 6-week French Contrast Method (FCM) to routine soccer training affects agility, vertical

Myofascial release techniques, particularly when applied using foam rollers, have gained prominence in sports science due to their potential benefits in enhancing athletic performance. This study delves into the impact of this technique on swimmers, a group where flexibility, jump capacity, and short-distance speed are paramount.The research engaged 12 male swimmers, all of whom had been active in the sport for a minimum of three years. Their average age stood at 19.58±.66 years, with an average height of 176.83±8.49 cm and body weight of 75.43±6.62 kg. Following a 5-minute low-intensity warm-up run, participants underwent 10 minutes of dynamic stretching exercises targeting major muscle groups involved in swimming. This was followed by a self-myofascial release (SMR) protocol using foam rollers, focusing on muscle areas most prone to tension and strain in swimmers. These protocols were applied consecutively at 48-hour intervals and at consistent times of the day to ensure uniformity.Post-protocol assessments revealed varying impacts on performance metrics. While the countermovement jump measurements remained statistically unchanged (p0.05), significant improvements were observed in the 15 m swimming (t: 2,307, p: ,041), squat jump (t:,-2,541, p:,027), and flexibility (t:-2,491, p:,030) tests (p0.05).These findings underscore the potential of integrating myofascial release techniques with foam rollers into swimmers' training regimens. Not only does this approach enhance specific performance parameters like squat jump and flexibility, but it also offers broader implications for the athletic community, emphasizing the importance of muscle relaxation and flexibility in achieving peak performance. Future research could delve deeper into the long-term impacts of such techniques and explore their efficacy across different athletic disciplines.Keywords: Flexibility, Foam roller, Jumping, Myofascial Release, Swimming

Bu araştırmanın amacı, lise öğrencilerinin fiziksel aktiviteye katılım motivasyonlarının incelenmesidir. Araştırmanın evrenini Mersin merkez ilçelerindeki liselerde öğrenim gören öğrenciler oluştururken, örneklemini ise bu liselerde öğrenimine devam eden 407 erkek ve kadın öğrenci oluşturmuştur. Araştırmada veri toplama araçları olarak Demir ve Cicioğlu (2018) tarafından geliştirilen Fiziksel Aktiviteye Katılım Motivasyonu Ölçeği (FAKMÖ)” ile kişisel bilgi formu kullanılmıştır. Araştırmanın veri analizinde SPSS paket programı kullanılmış olup veriler normal dağılım gösterdiği için ikili karşılaştırmalar Independent sample (t-test), çoklu karşılaştırmalar tek yönlü varyans analizi ANOVA testi ile analiz edilmiştir. Gruplar arasındaki farkın kaynağını belirlemek için ise post-hoc testlerden ‘’Tukey testi’’ kullanılmış ve anlamlılık düzeyi p<0.05 olarak kabul edilmiştir. Araştırmada cinsiyet, sınıf, lise türü, haftalık fiziksel aktivite seviyesi, düzenli spor yapma ve spor kulübünde oynama değişkenlerinde istatistiksel açıdan anlamlı farklılıklar tespit edilmiştir (p<0.05).Sonuç olarak erkeklerin, alt sınıf öğrencilerinin ve egzersize daha fazla vakit ayıran grupların fiziksel aktiviteye katılım motivasyonlarının daha yüksek olduğu belirlenmiştir. Dolayısıyla fiziksel aktiviteye katılım sürelerinin artırılmasının hem adölesan dönemde gençlerin fiziksel ve sosyal gelişimlerine önemli katkılar sağlayacağı hem de birçok sağlık probleminin önüne geçerek daha sağlıklı bir yaşam sürme olasılığını artıracağı söylenebilir.

The purpose of this study is to examine the relationships between university students’ healthy lifestyle behaviors and their knowledge and risk perception levels regarding cardiovascular diseases, and to identify the factors that predict healthy lifestyle behaviors. In this context, the predictive role of demographic variables, health history, lifestyle habits, and knowledge level about cardiovascular diseases on healthy lifestyle behaviors was evaluated. The research was conducted using data obtained from 489 full-time students aged 18 and over studying at a state university in the Mediterranean Region. A quantitative cross-sectional correlational design was adopted to examine the determinants of healthy lifestyle behaviours among university students. The data collection tools used in the study were the “Cardiovascular Disease Risk Factors Knowledge Level (CARRIF-KL) Scale” and the “Healthy Lifestyle Behaviors Scale-II (HLBS-II)”. The data were analyzed using Pearson correlation analysis and four-stage hierarchical multiple regression analysis. A preliminary power analysis was performed using the total R² value as a guide to determine the sample size required for hierarchical multiple regression. The findings showed that knowledge about cardiovascular diseases, awareness of risk factors, and cognitive awareness of the consequences of risky behaviors are important and positive predictors of healthy lifestyle behaviors. Furthermore, lifestyle habits such as smoking, consumption of processed foods, and frequent exposure to stress were found to be important negative predictors of these behaviors. In this regard, the study emphasizes the importance of both risk perception and informative interventions in promoting healthy lifestyle habits among young adults.
