Öğe Acute Effects of Self-Myofascial Release Through Foam Roller and Static Stretching Methods on Vertical Jump Performance of Taekwondo Players(Researchtrentz Acad Publ Education Services, 2022) Akarsu, Mehmet; Kurhan, Cihad Onur; Ilbak, Ismail; Altuntop, Recep; Gonc, Mesut; Stojanovic, Stefan; Purenovic-Ivanovic, TijanaThe objective of this research is to examine the acute effects of self-myofascial release through foam roller and static stretching methods on the vertical jump performance of taekwondo players. In this cross-sectional study, a randomized controlled experimental method, one of the quantitative research models, was used. 21 taekwondo players participated in this research voluntarily. The mean age of the participants was 15.95 +/-,865; the mean height was 172.90 +/- 3,846 and the mean body weight was 61,86 +/- 5,379. On the first day of the study, low-paced jogging was performed for 5 minutes at a heart rate of 120 (RS V800) and then their vertical jump performance was measured. On the second day of the research, low-paced jogging was performed for 5 minutes, and then a static stretching protocol was applied to taekwondo players, and then their vertical jump performance was measured. On the third day of the research, low-paced jogging was performed for 5 minutes and then self-myofascial release through foam roller protocol was applied to taekwondo players and then their vertical jump performances were measured. As a result of the research, it was determined that there was no statistical difference between 5 minutes of jogging at a slow pace and static stretching. However, it was determined that there were statistically significant differences both between 5 minutes of jogging at a slow pace and self-myofascial release and between static stretching and self-myofascial release (p<0.05). In conclusion, it can be said that self-myofascial release through foam roller exercises can affect vertical jump performance positively and at an acute level.Öğe The Effects of Different Stretching Techniques Used in Warm-Up on the Triggering of Post-Activation Performance Enhancement in Soccer Players(Mdpi, 2024) Kurak, Kemal; Ilbak, Ismail; Stojanovic, Stefan; Bayer, Ramazan; Purenovic-Ivanovic, Tijana; Palka, Tomasz; Ambrozy, TadeuszThe aim of this research was to investigate the effects of different stretching techniques used during warm-up exercises prior to post-activation performance enhancement (PAPE) on the explosive lower extremity strength performance of soccer players. This cross-sectional study involved the participation of 13 male soccer players with an average age of 22.38 +/- 1.75, body height of 174.38 +/- 3.94, and body mass of 72.30 +/- 4.13. To determine the participants' maximal strength performance, one repeated maximal strength (1-RM) squat exercise was applied. The PAPE protocol was then implemented with a squat exercise consisting of three repetitions at 80% of 1-RM. The warm-up protocols consisted of 5 min of cycling, followed by dynamic stretching, static stretching, or proprioceptive neuromuscular facilitation (PNF) stretching exercises. These protocols were applied on four different days with a 72 h interval. A vertical jump test was conducted to measure the participants' explosive strength performance. The research data were analyzed using IBM Statistics (SPSS version 26.0, Armonk, NY, USA) software. The findings of this study revealed statistically significant differences in vertical jump performance values after PAPE among participants based on the different stretching techniques used during warm-up (p = 0.00). In this context, the research concluded that dynamic stretching is the optimal stretching technique during warm-up exercises before PAPE to maximize its effects. On the other hand, static stretching was found to negatively affect performance by absorbing the PAPE effect.Öğe Effects of Swimming on the Body Composition of Individuals with Down Syndrome: A Systematic Review(Anadolu Univ, 2022) Sekban, Gulsah; Stojanovic, Stefan; Ilkim, Mehmet; Ilbak, Ismail; Jorgic, BojanIn the literature, it has been determined that various training models are applied to optimize the body health and body composition of individuals with Down Syndrome (DS). Although it has been reported in review studies that many training models are effective in improving the body health and body composition of individuals with DS, there is no consensus among researchers about how swimming exercises affect the body health and body composition of individuals with DS. In this context, the aim of the research is to reach a conclusion by utilizing the studies examining the effects of swimming on the body compositions of individuals with DS. This research was designed using the systematic review method and findings were obtained through this method. A total of 8689 articles were found in the search made on Web of Science and Google Scholar databases, and as a result of the evaluation made within the scope of the inclusion and exclusion criteria of the research, 8 articles were included in the research. As a result of the research findings, it has been concluded that there is no consensus among researchers about the effects of swimming on the body composition of individuals with DS, and also that very few studies have been conducted on this subject. Therefore, it is recommended to conduct more research on this subject.Öğe Examination of Anthropometric Profiles of Individuals Who Exercise in the Gym(Lahore Medical & Dental Coll, 2022) Kilincarslan, Gokmen; Ilbak, Ismail; Sadir, YunusBackground: Anthropometric measurements frequently used in sports sciences and public health is to be informed about the body composition of individuals are simple, cheap, easy and reliable methods. Some of these measurements are body mass index (BMI), waist circumference and waist hip ratio (WHR) measurements. Aim: The aim of this study is to examine the BMI and WHR values of the individuals who exercise at least two a weak in the gym in terms of age and gender by benefiting from anthropometric measurement methods. Methods: The study involved 528 volunteer individuals, including 72 men (13.6%) and 456 women (86.4%) between the ages of 18 and 65 who exercised in the gym at least two days a week in Malatya, Turkey. The mean age of the participants was 28.56 +/- 9.96, the height average was 1.65 +/-.08 and the body weight average was 72.60 +/- 14.35. The heights of all participants were taken with a wall-mounted stadiometer (Holtain Ltd., England), their body weights were taken with an electronic scale (Seca, Germany), and their diameter-circumference measurements (hip, waist) were taken with a gullick meter. Results: According to the age variable of the research group, it was determined that there was a low, positive and linear relationship between BMI (r=,361; p<0.05) and WHR (r=,272; p<0.05), and this relationship was statistically significant. In addition, it was determined that there was a statistically significant difference between BMI and WHR averages depending on the gender variable (p<0.05). Conclusion: As a result, there is an increase in BMI and WHR with the progress of the age. Similarly, as a result of the increase of BMI, WHR is also increased. While the mean BMI is higher in women than in men, WHR is higher in men than in women.Öğe Examination of the Effects of Autogenic Training on the Reaction Time Performance of the National Badminton Athletes(Lahore Medical Research Center Llp, 2021) Ugurlu, Dondu; Ilbak, Ismail; Akarsu, MehmetBackground: Although there is a consensus among researchers that autogenic training has positive effects on the psychological state of athletes, there have not been enough studies on its effects on physical performance yet. Therefore, the effects of autogenic training on physical performance is an important question that remains to be clarified. The fact that there is no research examining the effects of autogenic training on reaction time performance constitutes the original value of the study. Aim: The aim of the study is to examine the effects of autogenic training applied during 8 weeks on the visual and auditory reaction time performances of national badminton athletes. Methods: 15 male (experimental group=8 and control group=7) national badminton player between the ages of 18-23 residing in the province of Malatya participated in the study voluntarily. In addition to the training program, autogenic training was applied to the experimental group for 8 weeks, 3 days a week, after warming up. The control group continued their regular training. In order to determine the effects of the training, the pre-test and post-test was applied to the participants. SPSS 23 Package Program was used for the analysis of the data. The data were evaluated with the Mann-Whitney U test, one of the Non-Parametric tests. The significance level was taken as p<.05. Results: The mean age of the experimental group (N=8) was 19.88 +/- 1.81, the mean height was 173.75 +/- 4.10, and the mean body weight was 68.13 +/- 5.52. The mean age of the control group (N=7) was 19.72 +/- 1.80, the mean height was 175.72 +/- 7.87, and the mean body weight was 67.58 +/- 6.61.It was observed that there was no statistically significant difference between the right and left hand visual reaction times and the right and left hand auditory reaction times of the experimental and control groups (p>.05). Conclusion: As a result, autogenic training does not have a statistically significant effect on the visual and auditory reaction time of national badminton athletes.Öğe Investigation of maximal strength performance in terms of training time routine(Iermakov S S, 2024) Ilbak, Ismail; Eken, Ozgur; Stojanovic, Stefan; Joksimovic, Marko; Pavlovic, Ratko; Radulovic, NikolaBackground and Study Aim In recent years, there has been a growing interest in understanding the relationship between daily training time, circadian rhythms, and athletic performance. The connection between daily training time, circadian rhythms, and athletic performance continues to be a subject of research debate. Therefore, the aim of this research is to investigate whether maximal strength performance is affected by daily training time routines. Material and Methods This cross-sectional study involved a total of 36 male bodybuilding athletes, who were divided into three equal groups (n=12); Noon Group, Afternoon Group, and Evening Group. The distinguishing feature amongst the groups was that they had been training at different times of the day for the past 6 months, and within each group, athletes had been training at the same time of day (Noon Group 12:00-14:00; Afternoon Group 17:00-19:00; Evening Group 21:00-23:00). A one -repetition maximum squat test was administered to each group with there being a 72 -hour interval between the tests. Results The findings from the research indicate that there is a relationship between athletes' daily training time routines and maximal strength performance. Athletes perform at their best during the time that corresponds to their daily training routine. The analysis reveals a statistically significant advantage in 1-RM squat performance for athletes adhering to their daily training time routines at various times of the day (p <0.001). Notably, Group Noon, Group Afternoon, and Group Evening achieved their highest 1-RM squat performance when following their respective daily training time routines. Conclusions Results underscore the importance of aligning training schedules with athletes' natural rhythms, enhancing performance optimization strategies. It is believed that effective planning for training time by coaches and conditioning experts, taking into account competition times, would be a valuable strategy.Öğe Investigation of the Acute Effects of Self-Myofascial Release Technique on Jump Performance Applied to Plantar Myofascial through Tennis Ball(Anadolu Univ, 2022) Ceviker, Abdulkerim; Eroglu, Seref; Ilbak, Ismail; Stojanovic, StefanThe aim of this study was to examine the acute effects of self-myofascial release technique applied to the plantar myofascial through tennis ball on jumping performance of taekwondo athletes. Randomized controlled experimental method was used in this cross-sectional study. 46 competitive taekwondo athletes with >= 3 years' experience participated in research voluntarily. Participants were randomly divided into two groups: control (mean age: 21.21 +/- 2.27; height 173.08 +/- 4.89; body weight 63.17 +/- 7.06) and experimental (mean age: 21.00 +/- 2.55; height 170.56 +/- 5.06; body weight 57.60 +/- 8.46). As a pre-test, the vertical jump performance values of both groups were taken after 5 minutes of running and 4-5 minutes of rest. After 48 hours, the vertical jump performance values of the control group were taken again after 5 minutes of running only. The vertical jump performance values of the experimental group were obtained after the self-myofascial release technique, which consists of three sets applied for 20 seconds each, following a 5-minute slow pace run. SPSS (SPSS version 26.0, Armonk, NY) was used to analyze the research data. As a result of the findings obtained in the study, it was observed that there were no statistically significant differences between the vertical jump performance pretest-posttest values of the control and experimental groups (p<.05). As a result, it was concluded that the self-myofascial release technique applied to the plantar myofascial by means of a tennis ball did not have an acute effect on the jumping performance of taekwondo athletes.
