Öğe Comparison and Relationship of Quadriceps Femoris Angle, Muscle Strength, and Balance in Athletes and Non-Athletes(Springer Heidelberg, 2023) Unuvar, Bayram Sonmez; Torlak, Mustafa Savas; Gercek, Hasan; Tufekci, Osman; Erdagi, Kenan; Isik, BulentObjectiveQ-angle is an important parameter to assess quadriceps muscle's function and its effect on knee. The present study aims to investigate the potential relationships between Q-angle, muscle strength, and balance in both athlete and non-athlete populations.MethodsFifty-six athletes and non-athletes aged between 18 and 20 were included in this cross-sectional study. The Q-angle of each participant was measured using a universal goniometer. Muscle strength was evaluated using hand-held dynamometer, and static and dynamic balance were assessed using the one-leg stand test and Y balance test, respectively.ResultsOur findings revealed that athletes had a significantly smaller Q angle than non-athletes (p < 0.05). Furthermore, male participants had both higher muscle strength and better static balance with eyes closed than female participants (p < 0.05). Similarly, athletes had both higher muscle strength and better static balance than non-athletes (p < 0.05). Moreover, we found that the dominant limb had a significantly smaller Q angle than the non-dominant limb (p < 0.05). However, we did not observe a significant relationship between Q angle and dynamic balance (p > 0.05).ConclusionOur study suggests that individuals who participate in sports have lower Q angle values than those who do not participate in sports. Additionally, gender differences may exist in muscle strength and static balance. Furthermore, the Q angle was found to be lower in the non-dominant extremity compared to the dominant extremity. Finally, our study revealed a significant association between Q angle and knee muscle strength and static balance. Further research is needed to elucidate the underlying mechanisms of these relationships.Öğe A different marker to determine arrhythmia potential between elite active cyclists and veterans: T peak T end(Wiley-Blackwell, 2015) Gormus, Z. Isik Solak; Isik, Bulent; Ciftci, Ozgur; Icli, Abdullah; Togan, Turhan; Aslan, Huseyin; Kutlu, Selim[Abstract Not Availabe]Öğe The effects of acute moderate intensity training on hematological parameters in elite para-badminton athletes(Imr Press, 2022) Erdogdu, Murat; Yuksel, Mehmet Fatih; Isik, Bulent; Boyali, Ekrem; Erdagi, Kenan; Sevindi, TarikBackground and objective: The knowledge on the effects of para-badminton sport on physiological parameters is relatively limited in the literature. This study aims to examine the effects of moderate intensity badminton training on the hematological parameters of elite para-badminton athletes. Methods: A total of 12 para-badminton athletes, 6 female and 6 male, with international competitive experience in the Turkish Para-Badminton National Team, participated in the study. A 90-minute badminton training was applied to the athletes for their technical and tactical development. A 4 mL blood sample was taken before and after the training. Hematological parameters were analyzed from these blood samples. White blood cells, red blood cells, platelets count, and their particular subgroups such as hemoglobin, hematocrit, granulocytes, and lymphocytes were examined as the hematological parameters in this study. Results: The findings revealed that the female para-badminton athletes exhibited a significant increase in white blood cells, granulocytes percentage, red blood cells, hemoglobin, hematocrit, platelets values after training compared to pre-training. It was determined that there were significant increases in white blood cells, granulocytes, granulocytes percentage, red blood cells, and hematocrit values for male para-badminton athletes after training compared to pre-training, and significant decreases in lymphocytes percentage values. Conclusion: In conclusion, the present study showed that a single 90-minute moderate-intensity badminton training session leads to physiological changes on the blood parameters of elite parabadminton athletes. These changes, which differ by gender, can affect the health and performance of the athlete.Öğe QUADRICEPS FEMORIS ANGLE OF ELITE AND NON-ELITE ATHLETES IN OLYMPIC STYLE WEIGHTLIFTING(Khyber Medical Univ, 2022) Erdagi, Kenan; Altunok, Mehmet Kaan; Tufekci, Osman; Ozel, Raif; Isik, Bulent; Unuvar, Sonmez BayramOBJECTIVE: To find out the quadriceps femoris angle (Q-angle) values of elite and non-elite athletes in Olympic style weightlifting. METHODS: This study included 22 male elite athletes that won medals in international Olympic style weightlifting championships and 22 male non-elite athletes who won medals in national Olympic style weightlifting championships. A goniometer was used to determine the angle of the quadriceps femoris muscle while the athletes were in supine position and the muscle was inactivated. Anthropometric measurements of right-left thigh and lower leg length, right-left thigh and calf girth, and pelvic width of athletes were obtained. One repetition maximum of snatch, clean and jerk and leg strength of the athletes was recorded. To study demographic characteristics and some anthropometric values of lower extremity of the athletes, t-Test was conducted for independent groups. To compare anthropometric measurements of rightleft lower extremity and right-left Q-angle values, paired sample t-Test was used. Right-left Q-angle values and relations among other variables were studied by Pearson correlation analysis. SPSS was used for all analyses. RESULTS: Mean age was 19.73 +/- 2.97 years and 18.73 +/- 1.55 years for of elite and non-elite athletes respectively. No significant difference was observed in demographic characteristics and in some anthropometric values of lower extremity of elite and non-elite athletes (p>0.05). However, right-left Q-angle o ovalues of non-elite athletes (10.14 +/- 1.55 degrees and 10.14 +/- 1.52 degrees, respectively) were ohigher than the right-left Q-angle values of elite athletes (8.32 +/- 1.39 degrees and o8.32 +/- 1.32 degrees, respectively) [p<0.003]. CONCLUSIONS: Olympic style weightlifting, which is maintained in elite level, affects the quadriceps femoris angle.
