    Is the vitamin D level important on isokinetic muscle strength in adolescent athletes?
    (Alanya Alaaddin Keykubat Üniversitesi, 2019) Ercan, Sabriye
    Aim: To determine the relation between vitamin D levels and isokinetic muscular strength in athletes, and to compare the muscular strength between athletes with and without vitamin D deficiency. Methods: The records in the sports medicine clinic were examined, where the general medical examinations and performance analyses of the athletes had been conducted. The data of the athletes were examined, whose serum 25-OH vitamin D levels had been determined and isokinetic knee flexion-extension muscular strength test had been conducted. Age, height, body weight, discipline of sports, the year of beginning to sports and training duration per week (hours/week) were recorded for each athlete. The athletes were separated into two groups as vitamin D levels below 20 ng/mL (Group 1) and above 20 ng/mL (Group 2). Results: There was not any statistically significant difference between the demographic data and training data of the groups (p> 0.05). Vitamin D deficiency was found in 44% of all the athletes. The average vitamin D level was 13.8 ng/mL for Group 1, and 27.2 ng/mL for Group 2 (p:0.001). The serum calcium and serum phosphor levels were similar (p> 0.05). The isokinetic muscular strength test did not yield a difference between the two groups. It was found that vitamin D levels did not show any correlation with demographic data, training details and with any parameter of muscular strength (p> 0.05). Conclusion: In this study, there are no difference in effect of vitamin D on muscle strength, but significant results could be obtained in other studies with large participants.

    Isokinetic evaluation of adolescent athletes with os good schlatter disease
    (Alanya Alaaddin Keykubat Üniversitesi, 2018) Aydin, Canan Gonen; Kargın, Deniz; Bayhan, Avni İlhan; Ercan, Sabriye; Örsçelik, Aydan
    Aim: Os Good Schlatter Disease (OGS) is a common condition for sportspeople during the growth period. The etiology is still unclear. Its definition is traction apophysis. The OGS knees are thought to have stronger muscle power. The aim of this study is to evaluate muscle strength in OGS knees. Materials and methods: We examined 96 athletes who applied to our clinic. We evaluated the muscular strength by separating the knees in two groups as the knees with OGS and without OGS. Knee muscle strength was measured in 60 and 180 degrees/second with isokinetic dynamometer CYBEX NORM (CSMI Humac Norm, ABD). Peak torque (PT), peak torque/body weight (PT/BW) and agonist/antagonist (flexor/extensor, AG/AN) values were collected. Independent samples t-test was used for statistical evaluation. Results: At 60 degrees, we found a significant difference between PTE, PTF, PT / BW E and PT / BW F (p= 0.02, p= 0.002). PTE, PDF, PT/ BWF were statistically significant also at 180 degrees (p= 0,00 ). Conclusion: Muscle strengths of the non-OGS group were statistically stronger than those of OGS group. In order to demonstrate better performance of the athletes with OGS, training plans should be conducted to increase their muscle strength.
