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: 4Accentuated Eccentric Load Training: Traditional Set Versus Cluster Set(Iermakov S S, 2022) Ersoz, Mehmet; Pinar, Salih; Kaya, SelmanBackground and Study Aim Material and MethodsThis study aims to comparatively analyse the effects of cluster set (CS) and traditional set (TS) applications on strength and power outputs in accentuated eccentric load (AEL) training. Thirty-two amateur male football players with at least 2 years of strength training history participated in the study (Xage: 18,78 +/- 0,83 years, Xheight:166,73 +/- 8,61 cm., Xbody weight: 69,59 +/- 6,03 kg.). Participants were randomly divided into two groups: CS (n=16) and TS (n=16). In both groups, the same "AEL Training" was applied and different set models were used. Augmented eccentric load (AEL) training was performed with 3 sets of 8 repetitions, 50% concentric and 80% eccentric of 1 Repetition Maximum (1-RM) and with a fast lifting tempo. The sets were completed with 20 seconds of rest after every two repetitions in the AEL-CS group and without any rest between repetitions in the AEL-TS group, and the training sessions were performed twice a week for 4 weeks. Countermovement jump (CMJ), 50cm drop jump-reactive strenght index (DJ-RSI) test, 1-RM strenght test, 10-20-30m sprint test and Illinois Agility Test (IAT) were performed on the athletes before and after the training.ResultsWhen analysing the data obtained in this study, Skewness and Kurtosis values and Kolmogorov-Smirnov values were examined to determine homogeneity. In order to compare the pre-test and post-test averages between groups, ANOVA was used for Repeated Measures, and Sample T Test was used to compare the pre-test and post-test averages within groups. The statistical significance level was determined as p<0.05. When the groups were compared, the difference in the improvement rate averages was tested. At the end of the four-week study, drop jump-reactive strength index (DJ-RSI), countermovement jump (CMJ), Illinois Agility Test (IAT) 10-20-30m sprint values and 1-RM values were improved percentage-wise in both AEL-CS and AEL-TS groups. Between the groups, a significant difference was observed between DJ-RSI, CMJ, and 10-20-m Sprint Test results (p<0.05). When we compare the results within groups, it can be concluded that the AEL-CS group showed more improvement in terms of strength, change of direction (COD) skills and Sprint compared to the AEL-TS group.ConclusionsIn conclusion, it can be advised to use cluster set in accentuated eccentric load training in order to improve strength, Sprint and COD skills.Article Citation - WoS: 1Effects of Triphasic Training Model Combined With Two Different Cluster Sets on Vertical Jump and Reactive Strength Index(Iermakov S S, 2022) Kaya, Selman; Pinar, SalihBackground and Study Aim This study aims to examine the effects of the Triphasic Training Model (TTM) applied with different set designs (15-30 sec intra-set) on reactive strength index (RSI) and vertical jump values. Material and Methods Sixteen male athletes over 18 with at least three years of strength training experience (2 days a week) actively engaged in sports participated in the study. The study group was divided into two groups by calculating the relative strengths. The 15-second cluster set (C15) group exercises were performed with 15 seconds of rest between repetitions, and the 30-second cluster-set (C30) group practiced the exercises with 30 seconds of rest between repetitions. The triphasic training model was applied to all study groups for six weeks. Countermovement jump (CMJ) and drop jump tests were performed on the athletes before and after the training. Optojump brand photocell system was used for CMJ and RSI tests. For the RSI test, the desk height was determined as 40cm. Kolmogorov-Smirnov values were examined to assess the homogeneity of the data. To compare the means between groups, ANOVA was used for Repeated Measures, and a t-test was used to compare the pretest-posttest mean of the groups. The statistical significance level was determined as p<0.05. Results After triphasic training, CMJ and RSI values of both C15 and C30 groups increased (p<0.05). When the within-group pretest-posttest values were examined, it was seen that the C30 group showed more improvement than the C15 group. Conclusions As a result, it was seen that the triphasic training model applied twice a week for six weeks improved the CMJ and RSI values of the athletes, and it was more effective to use C30 instead of C15 in the use of cluster sets.
