Öğe An online pilates exercise program is effective on proprioception and core muscle endurance in a randomized controlled trial(Springer London Ltd, 2022) Suner-Keklik, Sinem; Numanoglu-Akbas, Ayse; Cobanoglu, Gamze; Kafa, Nihan; Guzel, Nevin A.Background Proprioception is important for stability of body segments, postural control, and functionality. However, there are no studies in literature showing effects of online Pilates exercises that create proprioceptive inputs on vertebra on trunk proprioception. Aims This study aims to reveal effect of online Pilates exercises conducted on trunk proprioception and core muscle endurance in healthy individuals. Methods We included thirty-three healthy individuals between ages of 18 and 25 in study. Individuals were randomly divided into two groups. There were 17 individuals in Pilates group (PG), and 16 individuals in control group (CG). The PG was given online Pilates exercises by the physiotherapist in groups 3 days a week for 6 weeks, 1 h a day. There was no exercise program recommended for individuals in CG. We evaluated trunk proprioception with an inclinometer, core muscle endurance with three core endurance tests created by McGill, and prone bridge tests. All evaluations completed just before start of study and 2 days after 6-week training. Results Two groups had similar demographic characteristics, and there was no difference between baseline measurements (p > 0.05). While improvement observed in PG in trunk proprioception and all of core muscle endurance tests (p < 0.05), no statistically significant difference reported in CG (p > 0.05). Conclusions We revealed that online Pilates exercises performed at mat level for 6 weeks in healthy individuals had positive effects on trunk proprioception and core muscle endurance with this study. Contribution of Pilates exercises to development of both muscular endurance and proprioceptive senses, even if performed at a distance, is important.Öğe Comparison of Shoulder Muscle Strength of Deaf and Healthy Basketball Players(Nevzat Demirci, 2020) Suner-Keklik, Sinem; Cobanoglu, Gamze; Savas, Seyfi; Seven, Barış; Kafa, Nihan; Guzel, Nevin A.Purpose: It has still not been made clear whether the audio inputs from the environment may have on the muscle strength characteristics of people who spend long periods of their lives with hearing loss. The purpose is to evaluate shoulder muscle strength and endurance of deaf basketball (DB) players and to compare them with healthy basketball (HB) players. Methods: The study was carried out with a total of 26-man players including 13 players (years: 24±3) in DB group and 13 players (years: 22±2) in HB group. Internal rotator (IR) and external rotator (ER) muscles strength of shoulder dominant and non-dominant side was measured using an isokinetic dynamometer. Results: According to isokinetic test results, there was not a difference between two groups on either dominant or nondominant side in terms of ER and IR Nm/kg (p>0.05). The ER / IR ratio was different between the two groups in favor of HB players (p=0.017). The strength parameters of dominant extremities of players in both groups were found to be higher than nondominant extremity. Conclusions: As a result, IR and ER muscle strengths were similar in two groups, both groups were at risk for musculoskeletal injuries in terms of ER/IR ratio. It could be speculated that it is essential to design training programs with additional ER strengthening exercises to improve the balance between IR and ER muscles and minimize risk of injury. The dominant extremity was found to be stronger in both groups. In our opinion, symmetrical movement patterns will positively affect performance on dominant extremity. © 2019 AME Publishing CompanyÖğe GENDER DIFFERENCES IN GAIT PARAMETERS OF HEALTHY ADULT INDIVIDUALS(Dokuz Eylul Univ Inst Health Sciences, 2023) Suner-Keklik, Sinem; Cobanoglu, Gamze; Ecemis, Zeynep Berfu; Guzel, Nevin A.Purpose: Anatomical and biomechanical differences between male and female are also known to cause differences in gait patterns. However, the results of the studies are contradictory. Furthermore, these studies focused only on some of the spatiotemporal parameters, and pelvic movements were not analyzed. The aim of the present study is to reveal the difference in gait parameters between male and female. Material and Methods: 44 female and 39 males were included in the study. BTS G-Walk system was used to evaluate the gait. After the accelerometer was placed, the participants were asked to walk 8 m. Spatiotemporal parameters and pelvic kinematics were recorded. Results: Given the spatiotemporal parameters, it was found that male and female were similar in terms of speed, % stride length and step length (p>0.05), while gait cycle duration, stride length, swing phase and single support phases were higher in male; and stance phase, first double support phases, cadence were found to be higher in female (p<0.05). In pelvic kinematics, male and female were similar in terms of rotation total range, gait cycle, pelvic tilt, obliquity and rotation symmetry index (p>0.05), while pelvic tilt total range was higher in male and obliquity total range was higher in female (p<0.05). Conclusion: The fact that gait differs not only in spatiotemporal parameters but also in pelvic oscillations due to anthropometric and biomechanical differences between male and female has shown that when evaluating individuals in the clinic, they should be compared and interpreted according to their own gender groups.Öğe Reliability and criterion validity of the Turkish version of the Recent Physical Activity Questionnaire(Gdansk Univ Physical Education & Sport, 2025) Dasdemir, Kubra Ayse; Suner-keklik, Sinem; Cobanoglu, Gamze; Guzel, Nevin A.Background: This study aims to determine reliability and criterion validity of the Turkish version of the Recent Physical Activity Questionnaire (RPAQ). Materials and methods: The study included 146 individuals aged 18-45 years. Translation and cultural adaptation of the questionnaire was performed with regard to an appropriate procedure. Test-retest reliability was analyzed in terms of intraclass correlation coefficient (ICC). For assessment of validity of the questionnaire, the criterion validity method was used. Criterion validity was evaluated using a pedometer, which is an objective measurement tool. The correlation between the total number of steps recorded during a week and RPAQ scores was examined. The validity was evaluated using Spearman correlation analysis. Results: The ICC value was 0.96 for total PAEE (physical activity energy expenditure) and between 0.77 and 0.97 for home, work, recreation, and transportation PAEE. The duration of intensity levels varied between 0.80 and 0.97. Test-retest reliability of RPAQ was high. A moderate correlation (r = 0.472) was found between the total value of RPAQ and the number of steps, and a weak- to-moderate correlation (r = 0.210-0.442) was found for other dimensions. No correlation was found with home activities. Conclusion: The Turkish version of RPAQ is valid and reliable. RPAQ can be used to assess the physical activity level of the Turkish population.Öğe Results Muscle Strength and Thickness After Anterior Cruciate Ligament Reconstruction with Hamstring Tendon Autografts: An Ultrasonographic and Isokinetic Evaluation(Galenos Publ House, 2021) Suner-Keklik, Sinem; Guzel, Nevin A.; Cobanoglu, Gamze; Gunendi, Zafer; Kafa, Nihan; Ataoglu, Muhammed BaybarsBACKGROUND/AIMS: This study aimed to compare the muscle strength and thickness of individuals who underwent anterior cruciate ligament (ACL) reconstruction using a hamstring tendon graft for at least 12 months with uninvolved limbs and healthy controls. MATERIALS and METHODS: This study included 25 individuals who underwent ACL reconstruction [age: 29.56 +/- 8.25 years; Body Mass Index (BMI): 27.27 +/- 3.89 kg/cm(2)] and 25 healthy participants (age: 27.12 +/- 5.94 years; BMI: 24.70 +/- 3.03 kg/cm2). Muscle thicknesses of the vastus medialis oblique (VMO), rectus femoris (RF), biceps femoris (BF), and semitendinosus-semimembranosus (SS) muscles were evaluated by ultrasonographic measurement. Muscle strength measurements using an isokinetic system were performed. RESULTS: VMO (p<0.001) and RF (p<0.001) muscle thickness were higher in the uninvolved limb than in the surgical limb. The concentric quadriceps muscle (p=0.029), eccentric quadriceps muscle (p=0.012), and eccentric hamstring muscle strengths (p=0.001) were significantly higher in uninvolved limb, which was similar concentric hamstring muscle strength (p>0.05). Muscle thickness and muscle strength of the control group and the surgical limbs were similar (p>0.05). CONCLUSION: An average of 3 years has passed since the operation; however, VMO and RF muscle atrophy and decreased hamstring and quadriceps muscle strength continued. These results revealed that the use of the limb, which has not fully achieved its functionality, is limited, and individuals try to compensate for this situation by the uninvolved limb.Öğe Static balance and proprioception evaluation in deaf national basketball players(Gdansk Univ Physical Education & Sport, 2021) Cobanoglu, Gamze; Suner-Keklik, Sinem; Gokdogan, Cagatay; Kafa, Nihan; Savas, Seyfi; Guzel, Nevin A.Background: Because of the proximity of anatomical structures involved in auditory and vestibular functions, complications concerning the inner ear may lead to problems involving both systems. This study investigated whether static balance and knee proprioception in deaf basketball players are different from those in individuals with normal hearing. Material and methods: 12 deaf national basketball players and 13 individuals with normal hearing were included. Static balance was evaluated using the Biodex-BioSway Balance System. Knee proprioception was assessed using a Dualer IQ Digital Inclinometer with the active angle repetition test. Results: The dominant-side mediolateral stability index and non-dominant-side overall, anteroposterior, and mediolateral stability index scores of deaf basketball players in the postural stability test were different compared with those of the individuals with normal hearing (p<0.05). There was no statistically significant difference between the two groups in terms of knee proprioception (p>0.05). Conclusions: Although there was no difference in knee proprioception in deaf basketball players, it is noteworthy that their postural stability was more impaired compared with that in individuals with normal hearing. Despite regular exercise, deaf basketball players had poorer balance than individuals with normal hearing. Therefore, balance and vestibular exercises should be added to the training programs of these athletes.Öğe What is the Optimal Frequency for Ankle Muscles During Whole-Body Vibration Exercises?(Int Journal Applied Exercise Physiology, 2019) Tor, Omer Burak; Ecemis, Zeynep Berfu; Cobanoglu, Gamze; Suner-Keklik, Sinem; Kafa, Nihan; Soylu, Ruhi; Guzel, Nevin A.Usage of the whole-body vibration (WBV) is effective in preventing the ankle injuries caused by increasing neuromuscular activity. The aim of this study was to investigate effective frequencies for neuromuscular activity of ankle muscles. A single-group, repeated-measures study design was used. Twenty-three healthy subjects (age 23.91 +/- 3.07, BMI 22.66 +/- 3.39) participated in this study. This study investigated the effects of WBV on the EMG responses of the Tibialis Anterior (TA), Peroneus Longus (PL), Gastrocnemius Medial (GM) and Lateral heads (GL). The muscle activity was measured with an 8-channel EMG Noraxon MiniDTS system (Noraxon, USA, Inc, Scottsdale, AZ) during 0, 20, 40 and 60 Hz of vibration. The Physio Plate (R) vibration platform (Physio Plate (R), Domino S.R.L, San Vendemiano, Italy) was used to deliver mechanical vibration. Compared with no vibration condition; EMG activity of all ankle muscles were significantly increased from at 60 Hz (123 % in TA, 64 % in PL, 53 % in GM, 77 % in GL) (p<0.01). At 40 Hz of vibration frequency, EMG responses of GM and GL was significantly increased (27 % and 53%, respectively) (p<0.01). Only GL was significantly increased of 33 % at 20 Hz (p<0.01). It could be concluded that using higher frequencies at whole-body vibration exercises are more effective than lower frequencies on ankle muscles' EMG activities. During squat exercises on the WBV platform, higher frequencies should be used to increase ankle muscle activation.Öğe WHOLE-BODY VIBRATION EFFECT ON MUSCLE ACTIVATIONS: WHICH ONE IS THE MOST EFFECTIVE, LOW FREQUENCY OR HIGH FREQUENCY?(Turkey Assoc Physiotherapists, 2024) Ecemis, Zeynep Berfu; Tor, Omer Burak; Cobanoglu, Gamze; Suner-keklik, Sinem; Kafa, Nihan; Guzel, Nevin A.Purpose: Whole Body Vibration (WBV) is a practice that passively applies mechanical oscillations to an individual from a support surface. The tonic vibration reflex response depends on the vibration localization, frequency, amplitude, and initial length of the muscle, but there is no consensus on what the optimal frequency should be. This study was conducted to examine the activation differences of lower extremity muscles at low and high frequencies during squat exercise on WBV. Methods: This study involved 16 healthy individuals (Age = 23.66 +/- 2.33 years, Body Mass Index = 22.59 +/- 3.86 kg/m2). WBV application was performed on a vertical vibration platform (GLOBUS Physioplate (R)). Participants performed static half-squats on WBV for 20 seconds under vibrating (20 Hz and 60 Hz; 2-3 mm amplitude) conditions. An 8-channel Electromyography (EMG) Noraxon MiniDTS system was used to measure the activation of the Gluteus Medius (GMed), Gluteus Maximus (GMax), Vastus Lateralis (VL), and Vastus Medialis (VM) muscles. Results: It was observed that there was a difference between the two frequencies for the activation of the VM, VL, and GMed muscles (p = 0.004, 0.001, 0.002, respectively). Vibration frequencies of GMed, VL, and VM muscle activities at high frequency were increased compared to low frequency. GMax did not show any statistically significant change between the two vibration conditions (p=0.013). Conclusions: Physiotherapists and trainers should prefer high frequencies in WBV applications, especially when they need to improve the neuromuscular response in the quadriceps and gluteus medius muscles.
