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 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.Öğe A study on the determination of handgrip strength of Olympic style weightlifting athletes(Iermakov S S, 2020) Erdagi, Kenan; Tufekci, Osman; Yeseri, Mustafa; Yuksel, Mehmet F.; Turgut, Nimet; Eroglu, Burak E.Purpose: Handgrip strength is widely accepted as a functionality parameter to assess upper extremity performance. The measurement of hand grip strength by dynamometry is a low cost, non-invasive method of simple applicability.The present study is based on the association of dominant and non-dominant handgrip strength with demographic and anthropometric characteristics; height, body weight, body mass index, upper arm length, forearm length, hand length, forearm circumference, upper arm circumference. Material: The study included 70 male athletes in olympic style weightlifting (age: 18.06 +/- 2.18, height:1.74 +/-.06 m, body weight: 76.09 +/- 13.04 kg). A total of 70 sedentary individuals as a control group (age 18.11 +/-.18, height:1.75 +/-.04 m, body weight: 74.01 +/- 13.94 kg) were also taken to compare study findings.The data obtained was analyzed by SPPS for Windows, version 25. Handgrip strength measurements were obtained by a Jamar dynamometer, according to the recommendations of the American Association of Hand Therapists. Results: It was found that the values of dominant and non-dominant handgrip strength, upper arm circumference and forearm circumference length of the weightlifting athletes were higher than those of sedentary individuals (p<.001). No asymmetry was observed in dominant and non-dominant handgrip strength values of the athletes and sedentary individuals. The correlations were noted between dominant and non-dominant handgrip strength values of weightlifting athletes and demographic characteristics, some anthropometric characteristics of upper extremity and weightlifting performance. Conclusions: The variability of handgrip strength might largely be explained by some anthropometric characteristics of upper extremity.Öğe A study on the determination of handgrip strength of Olympic style weightlifting athletes(Iermakov S S, 2020) Erdagi, Kenan; Tufekci, Osman; Yeseri, Mustafa; Yuksel, Mehmet F.; Turgut, Nimet; Eroglu, Burak E.Purpose: Handgrip strength is widely accepted as a functionality parameter to assess upper extremity performance.
