Article The Effect of Combined Core Training Intervention on Ball Throwing Velocity and Jump Performance in Competitive Young Female Handball Players(Iermakov S.S., 2025) Akalp, Ugur; Pinar, Salih; Pinar, YelizBackground and Study Aim Handball is a dynamic team sport that requires a combination of technical, tactical, and physical abilities. Among the key physical components, throwing velocity and vertical jump performance are essential for successful gameplay. These skills rely not only on upper and lower limb strength but also on core muscle function. The aim of this study is to investigate the impact of a combined core training intervention on ball throwing velocity and vertical jump performance in young competitive female handball players. Material and Methods A total of 28 young female handball players ((X) over bar = 17.21 +/- 0.74 years, 169 +/- 5 cm body height, 62.07 +/- 7.43 kg body weight) participated in the study. They were divided into an experimental group (EG = 14) and a control group (CG = 14). Both groups underwent a pretest to assess ball throwing velocity and vertical jump performance. After the initial measurements, the CG followed a standard training regimen. The EG completed an intervention program comprising six combined core exercises, performed three times per week for eight weeks. The same measurements were repeated after the program. A 2x2 repeated measures ANOVA was used to determine differences between EG and CG. The main effects of time (pretest and posttest), group, and the time*group interaction were evaluated. Results No changes were observed in the ball throwing velocity or jump performance of the CG between pretest and posttest. However, significant improvements were found in the EG for both ball throwing velocity and vertical jump performance (F = 47.467, p <.001, eta(2) =.646). Conclusions Designing core training programs in a sport-specific manner plays a significant role in developing athletes who require both general and specialized training.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.
