    The Effect of Hamstring Eccentric Strength and Asymmetry on Acceleration and Vertical Jump Performance in Professional Female Soccer Players
    Badau, A; Cengiz, SS; Karesi, H; Er, B
    The aim of this study was to investigate the relationship between eccentric hamstring muscle strength and acceleration and vertical jump in professional female soccer players. Twentieth professional female soccer players actively playing soccer participated in the study voluntarily with age (arithmetic mean +/- standard deviation) 18.31 +/- 5,97. The NORDBORD device was used to measure the participants' hamstring eccentric force output, the SmartspeedTM Contact Mat was used for vertical jump performance and the FUSIONSPORTS SmartspeedTM PRO photocell (Fusion Sport, Queensland, Australia) was used for 0-20m sprint performance measurements. When the relationship between eccentric hamstring strength parameters, vertical jump and sprint performance of the participants was analyzed, no significance was found. It is seen that there is a negative relationship between VJ and 0-5m at a moderate level (r=-586, p=.022) and a negative relationship between VJ and 0-20m at a high level (r=-.793, p=-.000). Since the studies examining the relationship between Hamstring Strength and Sprint performance are limited in number, it is not possible to reach a definite conclusion, more comprehensive and more studies are needed.

    The Relationship between Sleep Quality and Posture: A Study on University Students
    Badau, A; Badau, D; Cengiz, SS; Coskun, ES
    The aim of this study is to investigate body posture, physical exercises, head-neck relationship, and sleep quality among university students. A total of 96 students, with an average age of 20.86 +/- 1.24 years and an average BMI of 23.41 +/- 2.56, voluntarily participated in the study. The REEDCO Posture Evaluation (RPE) was used to assess the participants' body posture scores. Head and neck measurements were taken using the Apecs-AI Posture Evaluation and Correction System (R) (Apecs Posture Analysis Pro Plus Version 8.2.6). Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Pearson correlation analysis indicated that increased caffeine consumption was associated with poorer sleep quality (r = 0.267, p < 0.05). Additionally, increased participation in physical activities was associated with improved sleep quality, with those engaging in sports having better sleep quality scores (r = -0.278, p < 0.05). As physical activity increased, REEDCO scores decreased (r = -0.423, p < 0.05), while scores for right head (r = 0.210, p < 0.05) and left head (r = 0.247, p < 0.05) increased. Significant negative correlations were found between REEDCO scores and right head (r = -0.296, p < 0.05) and left head (r = -0.463, p < 0.05) scores. In conclusion, due to the limited number of studies investigating head-neck relationships and sleep quality, definitive conclusions cannot be drawn; further and more comprehensive research is needed.
