Article Citation - WoS: 2Citation - Scopus: 1Isokinetic Knee Muscular Strength Is Associated With Hematologic Variables in Female Modern Dancers(Spanish Assoc Sports Performance Analysis-aearedo, 2018) Agopyan, Ani; Tekin, DemetIt is important to expose the risk factor in injury in the context of the health and the careers of dancers. Female are at greater risk of developing anemia than men, yet scarce data exist on anemia associated outcomes in female dancers. The aim of the present study was to investigate the relationships between bilateral isokinetic knee extensor and flexor muscles strength, and biochemical hematologic parameters in female modern dancers. Concentric isokinetic peak torque [(PT)-N.m], peak torque % body weight [(PT% BW)-N.m.kg(-1)], average peak torque [(AVGPT)-N.m] and total work [(TW)-J)] of the knee extensor and flexor muscles were measured at a velocity of 60 degrees, 180 degrees and 300 degrees s(-1). To determine hematological parameters [red blood cell count (RBC), hematocrit (Hct), and Hb] were determined. The dancers of LHG and HHG had significant differences (p <= 0.05) for hematological parameters. HHG dancers' strength production in extensors muscles of PT, TW and AVGPT in non-dominant left leg (p <= 0.05) were significantly higher than LHG dancers. There were significant (p <= 0.05) negative correlations between TW (300 degrees s(-1)) of left leg extensor muscles and RBC, Hct and Hb variables. Isokinetic knee muscular strength is associated with hematologic variables in female modern dancers. The current study provides evidence that the low-level hematologic parameters has decreased performance on torque production of extensors knee muscles in non-dominant leg during isokinetic muscle strength endurance in female modern dancers.Article Citation - WoS: 4Citation - Scopus: 6A Systematic Approach for Improving the Software Management Process(World Scientific Publ Co Pte Ltd, 2019) Birgun, Semra; Cerkezoglu, Burcu TanrikutInformation technology is an indispensable element in applications in today's industrial era. In addition to modern management approaches, software just as well as hardware is of great importance to ensure competitive advantage if the company needs to keep pace with industrial requirements. Information sector can be seen as a competition opportunity for emerging countries. To be able to exploit this opportunity, companies need to be agile and innovative. In this paper, we suggest a process innovation which is intended to be a new model for designing an efficient and effective software process. The model was applied at a software company, and the results of this study are reported here. Lean and agile approaches were used, and as a result, the firm achieved significant improvements in cost, time, labor force, quality, internal and external customer satisfaction, speed, reliability and productivity.Article Citation - WoS: 5Citation - Scopus: 6Skeletal Muscle Fatigue Does Not Affect Shooting Accuracy of Handball Players(Ios Press, 2019) Akyuz, Beyza; Avsar, Pinar Arpinar; Bilge, Murat; Deliceoglu, Gokhan; Korkusuz, FezaBACKGROUND: Shooting accuracy and ball speed are important factors relating to scoring in handball that could be affected by skeletal muscle fatigue. OBJECTIVE: To explore the effects of muscle fatigue on male handball players' shooting accuracy and ball speed. METHODS: Sixteen elite handball players (M-age = 17.1 +/- 1.7 years) participated in the laboratory and the field-testing sessions. Running speeds equal to 75% of participants' maximal oxygen uptake (VO2max) values from laboratory tests were used as the initial velocity for the 30-15 intermittent fitness test (30-15(IFT)) in the fatigue protocol. Participants shot to the target at random visual signals placed behind the target before and after fatigue. In order to measure wrist acceleration and ball speed, an accelerometer and a radar gun are used respectively and numbers of accurate and inaccurate shots also recorded. RESULTS: There were no significant differences between pre-fatigue and post-fatigue protocols in terms of accurate and inaccurate shots, and ball speed. Only wrist acceleration in the Y axis (M-pre(-fatigue) = 33.12, SD = 1.17msec; M-post - fatigue = 34.50, SD = 1.21msec) was affected by the fatigue protocol in inaccurate shots (p = 0.042). CONCLUSIONS: Muscular fatigue does not affect shooting accuracy and ball speed in male handball players.
