    The Acute Effects of Various Dynamic Stretching Exercises on Jump Performance and Range of Motion
    (Universidad de Murcia, 2025) Savaan, Mustafa; Pmar, Yeliz; Pmar, Salih; Savaşan, Mustafa; Pinar, Salih; Pinar, Yeliz
    This study aimed to investigate the acute effects of different dynamic stretching (DS) protocols on vertical jump performance and range of motion (ROM). Thirty healthy male participants, with an average age of 23.48 years, body weight of 76.90 kg, and height of 181.87 cm, who had engaged in recreational exercise for at least two years, participated voluntarily. A "cross-controlled randomized" experimental design was utilized to assess four distinct DS protocols: a-DS at 100 bpm for 30", b-DS at 100 bpm for 75" s, c-DS at 150 bpm for 30", and d-DS at 150 bpm for 75". Acute ROM was measured using the Passive Straight Leg Raise Test (PSLR), while jump performance was assessed via countermovement jump (CMJ). Data were analyzed using repeated measures ANOVA and paired samples T-tests with significance set at p<.05. All four DS techniques significantly increased angles measured by PSLR following application (p <.05). CMJ values also showed significant improvements in both groups subjected to the shorter protocols lasting 30"at either tempo (p <.05). Consideration should be given to application duration and tempo when planning DS exercises, as structured warmup routines can enhance flexibility and optimize athletic performance.

    Determining the Injury Risk Levels of Kyorugi and Poomsae Taekwondo Athletes and Comparing Them With Selected Athletic Performance Parameters
    (Stowarzyszenie Idokan Polska-Idokan Poland Assoc, 2025) Ergin, Ceren z.; Pinar, Yeliz; Sani, Fatih; Cumbur, Cansel; Ramazanoglu, Nusret
    Background. Different disciplines within the same sport can lead to varying injury risks and performance requirements due to differences in energy systems, techniques, and competition rules. Problem and aim. This study assesses and compares injury risk levels among taekwondo athletes in the kyorugi and poomsae disciplines alongside selected athletic performance parameters. Material and Method. The study included 10 women (22 +/- 2.37 years) and 10 men (22 +/- 1.25 years) from the kyorugi discipline, and 10 women (19.4 +/- 2.55 years) and 10 men (18.8 +/- 3.29 years) from poomsae. All participants had competed in licensed elite-level competitions for at least 4 years. Injury risk and performance were evaluated using the Y balance test (YBT), reactive strength index (RSI), and functional movement screen (FMS). Results. Significant differences were found between male kyorugi and poomsae athletes in rotary stability (p=0.042), dominant leg Y balance (p=0.012), and composite scores (p=0.012). For female athletes, differences in dominant leg Y balance (p=0.049), anterior reach (p=0.027), RSI (p=0.001), and jump height (p=0.001) were noted. Female poomsae athletes had RSI values below normative standards. According to the YBT, the male poomsae group had the lowest number of athletes at risk of injury, whereas the female kyorugi group had the highest. Conclusions. Generally, taekwondo athletes displayed low injury risks based on FMS and YBT values, with moderate to low RSI risk levels. Increased reactive strength may correlate with higher injury risk. Female poomsae athletes should work to improve RSI scores, while kyorugi athletes should focus on strategies to address asymmetry-related injuries.
