The aim of this study was to evaluate the effect of different joint positions, rotator cuff muscle fatigue and experience on shoulder proprioceptive sense among male volleyball players. The participants of the study were 20 experienced (Mage= 20.7 ? 2.8) and 20 inexperienced (Mage= 17.1 ? 1.0) male volleyball players being members of first league volleyball teams. Measurements were made by Biodex System 3 pro (Biodex Medical Systems, Inc., New York, USA) and only dominant extremities were assessed. Shoulder proprioceptive sense was determined by measuring participant2s perception of joint position sense with the joint at 90? abduction, external rotation and 90? abduction, neutral rotation. Participants were tested at a speed of 2 deg/s before and after exercising on an isokinetic testing machine until fatigued. Fatigue protocol was practiced at 60 deg/s and it was terminated when the internal rotation maximal peak torque decreased by 50%. There was significant difference between proprioceptive sense of inexperienced volleyball players at 10?-20? (p< .01) and 15?-20? (p< .05) in external rotation before fatigue. The difference between before and after fatigue proprioceptive sense of experienced volleyball players at 20? (p< .05) was found statistically significant, whereas the significant difference was observed between before and after fatigue proprioceptive sense of inexperienced players at 10? (p< .01) and 15? (p< .05) in internal rotation. It was concluded that the effect of fatigue on proprioceptive sense is related with experience, but experience itself had no effect on proprioceptive sense.

Shoulder proprioception in male tennis players between ages 14-16
Boyar, Alaaddin; Korkusuz, Feza; Department of Physical Education and Sports (2006)
Proprioceptive information appear to play an important role in stability and movements of shoulder joint in sporting activities especially in tennis. The purpose of this study was to measure the shoulder proprioceptive differences, and assess proprioceptive sense between dominant and non-dominant shoulders between male tennis players and controls between ages 14 - 16. 15 young male tennis players with a mean age 14.6 ± 0.7 years and 15 young male sedentary individuals with a mean age 14.8 ± 0.9 years partic...
Variations in Central Adiposity, Cardiovascular Fitness, and Objectively Measured Physical Activity According to Weight Status in Children (9-11 Years)
Söğüt, Mustafa; Clark, Cain C. T.; Nikolaidis, Pantelis Theodoros; Rosemann, Thomas; Knechtle, Beat (Frontiers Media SA, 2019-07-24)
The purpose of this study was twofold: first, to compare the central adiposity (CA), cardiovascular fitness (CF), and physical activity (PA) in children with different weight status, and second, to determine the associations between moderate to vigorous physical activity (MVPA) and measures of adiposity [CA and body mass index (BMI)] and CF. A sample of 244 children (boys = 120 and girls = 124), 9.7-10.8 years of age (10.3 +/- 0.3 years), was measured for stature, body mass, waist circumferences, and 20-m m...
The Effects of dynamic and static stretching protocols on power, agility and flexibility in elite wrestlers
Çelebi, Murat; Kirazcı, Sadettin; Department of Physical Education and Sports (2014)
The purpose of this study was to investigate the effects of static stretching (SS), dynamic stretching (DS) and no stretching (NS) protocols on power, agility and flexibility in competitive wrestlers. 34 competitive male athletes were recruited for Standing Long Jump, T-Drill and Sit and Reach Test to test power, agility and flexibility of the subjects respectively. The participants performed one of the tests on each day. After the analysis of repeated measures of ANOVA, the results indicated that the measu...
Effects of muscle fatigue on shooting accuracy in handball players
Şimşek, Beyza; Korkusuz, Feza; Department of Physical Education and Sports (2012)
The purpose of the study was to investigate the effects of muscle fatigue on shooting accuracy in male handball players. Sixteen elite young male handball players (age: 17.12±1.74 year; height: 185.26±7.17; body mass: 78.93±11.07) volunteered to participate in the study. The study composed of laboratory and field test sessions. In the laboratory test, maximal oxygen consumption (VO2max) obtained from treadmill running test, blood lactate concentration, heart rate monitoring at resting and every 3 minutes du...
Effects of swiss ball training on knee joint reposition sense, core strength and dynamic balance in sedentary collegiate students
Cuğ, Mutlu; Korkusuz, Feza; Department of Physical Education and Sports (2012)
The purpose of this study was to investigate the effects of Swiss ball training on (1) knee joint reposition sense (knee proprioception), (2) core muscle strength and (3) dynamic balance in sedentary collegiate students. In this thesis, two different participant groups and two different training methods were used. In order to evaluate the effect of Swiss ball training on knee proprioception and core strength, 3 days per week training was conducted throughout 10 weeks (Study 1). In order to evaluate the effe...
