    Acute effects of different warm-up methods on free kick performance in amputee soccer players; [Effetti acuti dei diversi metodi di riscaldamento sul rendimento dei giocatori amputati nel battere i calci di punizione]
    (Edizioni Minerva Medica, 2018) Yildiz S.; Kayihan G.; Gelen E.; Çilli M.; Özkan A.
    BACKGROUND: There are studies documenting the detrimental effects of static stretching and useful effects of dynamic exercises. However, there is no study which has researched the acute effects of different warm-up exercises on free kick performances in amputee soccer. The purpose of this study was to compare the acute effects of static stretching and dynamic warm-up exercise on free kick performance in amputee soccer players. METHODS: Twelve amputee soccer players playing for the national team (mean age 28±7 years) were investigated in our study. This study was designed to determine the acute effects of 3 different warm-up (WU) methods static stretching (SS), dynamic exercises (DYN) and control (NS) on anaerobic performance (free kick speed performance) RESULTS: Although significant differences (P<0.001) were found for DYN and NS when the free kick speed levels of the soccer players were compared pre and post-test; no obvious difference (P>0.05) was found for SS. The data shows that there is a significant increase in free kick speed for DYN and NS according to pre and post-tests results. CONCLUSIONS: The results of this study suggest that it may be desirable for amputee soccer players to perform dynamic exercises before performing activities that require a high power output. © 2018 Edizioni Minerva Medica.

    The relationship between reaction time, agility and speed performance in high-level soccer players
    (A. CARBONE Editore, 2020) Yildiz S.; Ates O.; Gelen E.; Cirak E.; Bakici D.; Sert V.; Kayihan G.; Ozkan A.
    Purpose: In soccer, reaction time (RT), speed and agility are important athletic skills that affect the performance of athletes. The aim of our study was to examine the relationship between these three athletic skills. Materials and methods: In this study, 73 high-level, active soccer players having at least 5 years of game experience (training age 10.72.9 years) participated voluntarily. The physical characteristics of the soccer players were: height (177.85.5 cm), weight (73.68.1 kg), and age (22.02.7 years). The participant's tests which were taken on non-consecutive days measured RT (Visual reaction test, Lafayette, Multi-Operational Apparatus for Reaction Time (MOART) system), speed (15 m, Fusion Sport, Smart Speed) and agility (open skills (OS) and closed skills (CS), Fusion Sport, Smart Speed). Results: A significant correlation was found between agility (CS) and speed (p0.05) however, there was no significant relationship between reaction time and agility (OS and CS) (p0.05). Conclusion: The important athletic skills of speed and quick change of direction were shown to have an effect on each other. It may be of benefit to add change of direction drills to training programs in order to improve the speed performance of the athletes. © 2020 A. CARBONE Editore. All rights reserved.

    Acute effects of static stretching and massage on flexibility and jumping performance
    (International Society of Musculoskeletal and Neuronal Interactions, 2020) Yildiz S.; Gelen E.; Çilli M.; Karaca H.; Kayihan G.; Ozkan A.; Sayaca C.
    Objective: The purpose of this study was to evaluate the effects of static stretching and the application of massage on flexibility and jump performance. Methods: Thirty-five athletes studying Physical Education at University (mean age 23.6±1.3 years, mean height 177.8±6.3 cm and mean weight 72.2±6.7 kg) performed one of three different warm-up protocols on non-consecutive days. Protocols included static stretching [SS], combined static stretching and massage [SSM], and neither stretching nor massage [CONT]. The athletes performed flexibility, countermovement jump (CMJ) and squat jump (SJ) tests. Results: SS and SSM protocols demonstrated 12% (p<0.05) and 16% (p<0.05) respectively greater flexibility than the CONT protocol. SJ and CMJ performances were significantly decreased 10.4% (p<0.05) and 5.5% (p<0.05) respectively after the SS protocol. There was no significant difference between SSM and CONT protocol in terms of SJ and CMJ performance. Conclusion: This research indicates that whereas static stretching increases the flexibility it decreases the jumping performance of the athletes. On the other hand, the application of massage immediately following static stretching increases flexibility but does not reduce jumping performance. Considering the known negative acute effects of static stretching on performance, the application of massage is thought to be beneficial in alleviating such effects. © 2020, International Society of Musculoskeletal and Neuronal Interactions.
