Publication The effect of static stretching of peroneal and tibialis anterior muscles on reaction time a randomized controlled study(Lippincott Williams & Wilkins, 2019-02-01) Arslan, Gufat; Şekir, Ufuk; ŞEKİR, UFUK; İlhan, Osman; Akova, Bedrettin; AKOVA, BEDRETTİN; Bursa Uludağ Üniversitesi/Tıp Fakültesi; 0000-0003-2735-8697; 0000-0003-1044-8805; AAM-4348-2020; AAI-4550-2021; ABC-8182-2021Objective: The aim of this study was to investigate the acute and chronic effects of static stretching on peroneal and tibialis anterior reaction characteristics.Design: All 23 participants who volunteered for this study were randomly divided into static (n = 12) and control (n = 11) groups. The subjects in the static stretching group performed stretching exercises for the ankle evertor and dorsiflexor muscles 5 days a week for 6 wks. Peroneal and tibialis anterior muscle reaction characteristics were evaluated at the beginning (2 times for acute effect) and end of this period. Electromyographic activity parameters of the muscles were measured using an ankle inversion tilting platform that simulated a sudden ankle inversion. The following were the four different ankle inversion conditions: (a) ankle-neutral, 15-degree inversion; (b) ankle-neutral, 30-degree inversion; (c) ankle-20-degree plantarflexion, 15-degree inversion; and (d) ankle-20-degree plantarflexion, 30-degree inversion.Results: Either in terms of acute or chronic effects, no significant differences were found after static stretching exercises for peroneal and tibialis anterior muscle reaction time, reaction duration, and muscle activity evaluated in four positions on the ankle inversion simulation platform (P > 0.05).Conclusions: In light of these results, it is possible to state that the short duration of static stretching exercises can still be applied before sports activities.Publication Effects of muscle architecture on eccentric exercise induced muscle damage responses(Uludağ Üiversitesi, Spor Tıp Bölümü, 2021-12-01) Senisik, Seher Cagdas; Akova, Bedrettin; Şekir, Ufuk; Gür, Hakan; AKOVA, BEDRETTİN; ŞEKİR, UFUK; GÜR, HAKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Spor Hekimliği Anabilim Dalı; 0000-0003-1044-8805; 0000-0003-2735-8697; AAI-4550-2021; AAM-4348-2020; JQZ-4279-2023There is a need to investigate the role of muscle architecture on muscle damage responses induced by exercise. The aim of this study was to determine the effect of muscle architecture and muscle length on eccentric exercise-induced muscle damage responses. Eccentric exercise-induced muscle damage was performed randomly to the elbow flexor (EF), knee extensor (KE), and knee flexor (KF) muscle groups with two week intervals in 12 sedentary male subjects. Before and after each eccentric exercise (immediately after, on the 1st, 2nd, 3rd, and 7th days) range of motion, delayed onset muscle soreness, creatine kinase activity, myoglobin concentration and isometric peak torque in short and long muscle positions were evaluated. Furthermore, muscle volume and pennation angle of each muscle group was evaluated before initiating the eccentric exercise protocol. Pennation angle and muscle volume was significantly higher and the workload per unit muscle volume was significantly lower in the KE muscles compared with the KF and EF muscles (p < 0.01). EF muscles showed significantly higher pain levels at post-exercise days 1 and 3 compared with the KE (p < 0.01 -0.001) and KF (p < 0.01) muscles. The deficits in range of motion were higher in the EF muscles compared to the KE and KF muscles immediately after (day 0, p < 0.01), day 1 (p < 0.05 -0.01), and day 3 (p < 0.05) evaluations. The EF muscles represented significantly greater increases in CK and Mb levels at day 1, 3, and 7 than the KE muscles (p < 0.05 -0.01). The CK and Mb levels were also significantly higher in the KF muscles compared with the KE muscles (p < 0.05, p < 0.01 respectively). The KF and EF muscles represented higher isometric peak torque deficits in all the post -exercise evaluations at muscle short position (p < 0.05 -0.001) compared with the KE muscle after eccentric exercise. Isometric peak torque deficits in muscle lengthened position was significantly higher in EF in all the post-exercise evaluations compared with the KE muscle (p < 0.05 -0.01). According to the results of this study it can be concluded that muscle structural differences may be one of the responsible factors for the different muscle damage responses following eccentric exercise in various muscle groups.Publication Covid-19 pandemic and anxiety related factors in patients treated in the emergency department(Mre Press, 2020-10-01) Durak, Vahide Aslihan; DURAK, VAHİDE ASLIHAN; Günay, Seyda; GÜNAY POLATKAN, ŞEYDA; Sığırlı, Deniz; SIĞIRLI, DENİZ; Akova, Bedrettin; AKOVA, BEDRETTİN; Armağan, Erol; ARMAĞAN, EROL; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Acil Tıp Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Kardiyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi /Spor Hekimliği Anabilim Dalı; 0000-0003-0836-7862; 0000-0003-1044-8805; AAA-7472-2021; AAI-4550-2021; AAH-8846-2021; AAI-5350-2021Aims: A novel coronavirus, now known as SARS-CoV-2019, suddenly emerged in Wuhan, China and within threemonths of the initial outbreak, the virus had spread rapidly to neighboring countries causing a pandemic. After the first case was announced, emergency departments were immediately reorganized as pandemic clinics. Special areas with maximum precautions were designed to evaluate patients. The majority of studies on this pandemic have focused on the treatment of respiratory symptoms and comorbidities in intensive care units. In this study, we sought to determine those factors that contributed to the anxiety level during the COVID-19 pandemic using the 'State' subscale of State-Trait Anxiety Inventory (STAI-S). Methods: A survey was performed in the emergency department by using an online questionnaire which consisted of demographic variables, questions about the opinions and behaviors of patients during the pandemic, diagnostic test results for COVID-19, and treatment methods. Results: There was a statistically significant difference between employment status (p < 0.001), monthly income (p < 0.001), the food consumption changes during the pandemic period (p = 0.001) and the estimated end-date for the COVID-19 pandemic (p < 0.001) and total STAI-S points. Conclusions: Our study has identified factors which significantly increase anxiety during the COVID-19 pandemic and identified those individuals who may benefit from psychiatric and social support.Publication Acute effects of static stretching on peak and end-range hamstring-to-quadriceps functional ratios(Baishideng Publishing Group Inc, 2015-10-18) Şekir, Ufuk; Arabacı, Ramiz; Akova, Bedrettin; ŞEKİR, UFUK; ARABACI, RAMİZ; AKOVA, BEDRETTİN; Uludağ Üniversitesi/Tıp Fakültesi/Spor Hekimliği Anabilim Dalı; Uludağ Üniversitesi/Spor Bilimleri Fakültesi/Beden Eğitimi ve Spor Bölümü; 0000-0003-2735-8697; 0000-0003-1044-8805; R-5044-2018; ABI-4831-2020; AAI-4550-2021; AAM-4348-2020AIM: To evaluate if static stretching influences peak and end-range functional hamstring-to-quadriceps (H/Q) strength ratios in elite women athletes.METHODS: Eleven healthy female athletes in an elite competitive level participated to the study. All the participants fulfilled the static stretching or non-stretching (control) intervention protocol in a randomized design on different days. Two static unassisted stretching exercises, one in standing and one in sitting position, were used to stretch both the hamstring and quadriceps muscles during these protocols. The total time for the static stretching was 6 +/- 1 min. The isokinetic peak torque measurements for the hamstring and quadriceps muscles in eccentric and concentric modes and the calculations for the functional H/Q strength ratios at angular velocities of 60 degrees/s and 180 degrees/s were made before (pre) and after (post) the control or stretching intervention. The strength measurements and functional strength ratio calculations were based during the entire-and end-range of knee extension.RESULTS: The pre-test scores for quadriceps and hamstring peak torque and end range values were not significantly different between the groups (P > 0.05). Subsequently, although the control group did not exhibit significant changes in quadriceps and hamstring muscle strength (P > 0.05), static stretching decreased eccentric and concentric quadriceps muscle strength at both the 60 degrees/s and 180 degrees/s test speeds (P < 0.01). Similarly, static stretching also decreased eccentric and concentric hamstring muscle strength at both the 60 degrees/s and 180 degrees/s test speeds (P < 0.01). On the other hand, when the functional H/Q strength ratios were taken into consideration, the pre-intervention values were not significant different between the groups both during the entire and end range of knee extension (P > 0.05). Furthermore, the functional H/Q strength ratios exhibited no significant alterations during the entire and end ranges of knee extension both in the static stretching or the control intervention (P > 0.05).CONCLUSION: According to our results, static stretching routine does not influence functional H/Q ratio. Athletes can confidently perform static stretching during their warm-up routines.
