Publication Open Access The association between isokinetic strength and strength asymmetry and jump performance in female volleyball players(2023-01-01) AYBERK, BAHAR; ÖZGÜL, BAHAR; POLAT, MİNE GÜLDEN; ATİK B., AYBERK B., ÖZGÜL B., POLAT M. G.Purpose: Since the use of normalized isokinetic strength was recently proposed to analyze sportive performance, it was aimed to examine relative isokinetic muscle strength as well as absolute strength in jump performance. Secondly, the investigation of the relationship between extremity-based and inter-extremity strength asymmetry and selected jump tasks was aimed. Methods: Thirty female professional volleyball players (23.70 ± 5.27 years) who has at least four training sessions per week participated to study during the pre-season period Peak torque (PT) of knee flexors and extensors at the speed of 60º/s and 180º/s were evaluated using isokinetic dynamometer. Jump height (cm) and relative power (W/kg) of vertical countermovement jump (CMJ) and squat jump (SJ) were tested by optojump photoelectric system. Results: A positive moderate correlation between PT and relative PT(rPT) at both speeds with jump height was detected (r = 0.365–0.594). It was found that jump power had a positive moderate to good correlation with PT(r = 0.557–0.731) and low to moderate correlation with rPT (r = 0.314–0.601). No significant correlation was found between hamstring/quadriceps ratio and bilateral muscle asymmetry with jump parameters (p > 0.05). Conclusions: Due to the relatively low level of relationship between normalized strength and performance, we suggest carrying out further studies examining the effects of normalized parameters on performance. Considering the findings based on strength asymmetry, the coordinated action of the relevant muscles may come to the forefront during the performance, rather than muscle strength.Publication Open Access Randomized controlled trial of an E-learningprogram for physiotherapy students to improve the management of rotator cuff related shoulder pain: a study protocol(2022-02-01) AYBERK, BAHAR; POLAT, MİNE GÜLDEN; Ayberk B., Polat M. G.Background:The majority of shoulder complaints are occurred due to rotator cuff pathologies. Although conservative treatments including physiotherapy are acknowledged as the first-line treatment approach in the management of shoulder pain, the uptake of physiotherapy practice is variable. One possible explanation of this could be the poor evidence-based knowledge mobilization to practice. The aim of the study was to evaluate the efficacy of an E-learning program on physiotherapy students\" knowledge of evidence-based Rotator cuff-related shoulder pain (RCRSP) management and their confidence in applying this care compared to a control group.Methods:A randomized controlled study will be carried with 146 fourth-year physiotherapy students. Students will be assigned to one of two groups: E-learning (N=73) or control (N=73). The outcomes will be: (1) RCRSP knowledge and clinical reasoning skills, and (2) self-reported confidence in RCRSP knowledge and clinical reasoning abilities. Both measurements will be held at baseline and post-intervention.Conclusions:This is the first trial to investigate if a specifically designed E-learning program besides a regular learning curriculum, improves students’ knowledge and self-confidence in the RCRSP management. Enhancing students’ after-graduation readiness to manage patients with RCRSP may help to allow patients access to evidence-informed physiotherapists.Trial registration:This trial was registered on clinicalTrials.gov on 17 June 2021 (NCT04952623)KeywordsE-learning, Rotator cuff injuries, Physiotherapy educationPublication Open Access ACUTE EFFECTS OF KINESIOTAPING ON BALANCE IN SALSA DANCERS(TURKEY ASSOC PHYSIOTHERAPISTS, 2020-08-22) AYBERK, BAHAR; Ayberk, Bahar; Uysal, Halil HakanPurpose: Non-professional salsa dance is a social, physical activity highly in demand. Since it is a vigorous physical activity, dancers are prone to have an injury during a dance performance, mainly in the ankle joint. In this study, the acute effects of kinesiotaping (KT) on balance in salsa dancers were investigated. Methods: This study was a single-blind randomized placebo-controlled trial, in which a total of 20 amateur salsa dancers (mean age=26.35 +/- 4.74 years), voluntarily participated. Participants were divided into two groups randomly by using a sealed envelope randomization method: KT Group (n=10) and Placebo-KT Group (n=10). A muscle correction technique that covers the ankle and peroneal muscle group were applied to KT Group one day after pre-tests. An I shaped placebo KT application was performed for the Placebo-KT Group. Flamingo balance test (FBT) and the Star Excursion Balance Test (SEBT) were used to assess balance performance. All tests were repeated immediately after the application. Results: In the intragroup analysis of the KT Group, SEBT scores showed a statistically significant increase (p<0.05) while there was no increase in FBT scores (p>0.05). We found no statistically significant difference in the intragroup analysis of Placebo-KT Group and the intergroup analysis of KT Group and Placebo-KT Group for both SEBT and FBT scores (p>0.05). Conclusion: While KT application has been found to be effective in improving dynamic balance, it was not effective in improving static balance performance.Publication Open Access Covid-19 Pandemisi Sırasında Üniversite Öğrencilerinin Fiziksel Aktivite, Depresyon, Stres, Uyku ve Yaşam Kalitesi Düzeylerinin İncelenmesi(2022-01-01) AYBERK, BAHAR; TİMURTAŞ E., AVCI E. E., AYBERK B., DEMİRBÜKEN İ., POLAT M. G.Amaç: Çalışmamızın amacı Covid-19 döneminde üniversite öğrencilerinin fiziksel aktivite, stres, depresyon ve uyku düzeylerinin, yaşam kalitesi ile ilişkisini araştırmaktı. Gereç ve Yöntem: Çalışmaya yaş ortalaması 20,51,4 yıl, boy ortalaması 166,98,0 cm, vücut kitle indeksi (VKI) 21,43,0 kg/cm2 olan 273 gönüllü katılımcı (229 kadın, 44 erkek) dahil oldu.

Methods: Eighteen male volleyball players volunteered to participate. All participants attended both MET trial for the GHJ horizontal abductors and sham trial. Preintervention and postintervention internal rotation (IR) and external rotation ROM and GHJ rotators isokinetic peak torque values were measured. Repeated measures one-way ANOVA and Bonferroni correction were used for analyzing the differences in the ROM and isokinetic parameters among the trials. Significance was defined as P <= .05. Results: The experimental group had a significantly greater increase in GHJ IR ROM postintervention compared to the control group (P = .005). No significant difference between the experimental group and control group was found for external rotation ROM (P > .05). However, a significant increase between the control/experimental and sham trials was found for external rotation ROM postintervention (P = .005). Besides, 60 degrees internal rotator (P = .001) and external rotator (P = .008), and 180 degrees internal rotator (P = .019) and external rotator (P = .049) peak torque values showed significant increase between the experimental and control/sham trials. Conclusion: A single application of an MET for the posterior shoulder provides immediate improvement in GHJ IR ROM and isokinetic peak torque values of both GHJ internal and external rotators in asymptomatic volleyball players.
