Article 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, YelizThis 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.Article Citation - WoS: 4Citation - Scopus: 4The Direct and Indirect Effects of Irrational Beliefs on Perceived Performance: The Mediation Role of Emotions and Automatic Thoughts(Springer, 2023) Urfa, Osman; Asci, Fevziye HulyaThe aim of this study was to examine the relationship between irrational beliefs and perceived performance and the atemporal mediator role of emotions and automatic thoughts in this relationship. A cross-sectional study design with a convenient sampling method was used in the study. Participants included 395 athletes from basketball, football, handball, and volleyball and consisted of 267 male (Mage = 20.73, SD = 2.37) and 128 female (Mage = 21.33, SD = 2.17) athletes who voluntarily participated in the study. Data was analyzed via a path analysis and irrational beliefs were shown to negatively predict positive emotions and positive automatic thoughts, but these beliefs positively predicted negative emotions and negative automatic thoughts. The direct effect of irrational beliefs on perceived performance was not significant, but its indirect effect on perceived performance through emotions and automatic thoughts was significant. Irrational beliefs negatively predict perceived performance through emotions and automatic thoughts. It is concluded that emotions and automatic thoughts play a significant role in the relationship between irrational beliefs and perceived performance.
