FACTORS AFFECTING BALL VELOCITY IN WELL-TRAINED FEMALE HANDBALL PLAYERS

In this study, we aimed to analyze whether a relationship between anthropometric and physical performance characteristics and ball velocity in different throwing techniques of well-trained female handball players exists. Twelve well-trained female handball players (age, 22.47±4.57 years; body mass, 66.70±11.05 kg; height, 167.33±7.41 cm; handball experience, 9.91±3.47 years) from a local team that participated in Turkey’s First Women’s Handball League were recruited in this study. Anthropometric measurements, body indexes, physical performance, and ball velocity were evaluated in all subjects. A positive relationship was found between ball velocity in 9-m throw after three steps a jump and arm span, bi-iliac breadth, and bi-acromial breadth (r2=0.49; p=0.03, r2=0.50; p=0.03 and r2=0.57; p=0.02, respectively) as well as between ball velocity in 9-m throw after three steps and a jump and Monourier index (r2=0.52; p<0.04). Ball velocity in 9-m throw after three steps and a jump was negatively related to Cormic index (r2=-0.52; p<0.04). Multiple linear regression analysis showed that all performance parameters affect neither the 7-m throw (R=0.85, R2=0.73; F(4-7)=1.61; p>0.33) nor the 9-m throw three steps after and a jump (R=0.88, R2=0.77; F(4-7)=1.96; p>0.26). However, a moderate positive relationship between 9-m throw after three steps and a jump and grip strength (r=0.54; p=0.03) and vertical jump height (r=0.53; p=0.03) was noted. Neither 7-m standing throw nor 9-m throw after three steps and a jump correlated with other variables. Arm span, bi-iliac breadth, bi-acromial breadth, Monourier index score, Cormic index score, vertical jump height, and grip strength may have a positive or negative effect on 9-m throw after three steps and a jump in well-trained female handball players. The results of this study may be useful in the identification of handball skills.  Article visualizations

Investigation of Academic Self Efficacy of University Students in the Sports Area

The purpose of this research; was to investigate the academic self-efficacy of the university students studying in the field of sports according to various variables. The sample group of the study consisted of 386 (female, 42.7% male, 57.3%) volunteer university students who were educated in physical education and sports teaching, sports management and coaching education departments by convenience sampling method. In order to collect the necessary information, a personal information form was used to determine the demographic characteristics of the participants and “Academic Self-Efficacy Scale'', which was conducted by Ekici (2012) was used for Turkish validity and reliability study. Kolmogorov-Smirnov test was applied to determine whether the data showed normal distribution. In the analysis of the data, independent sample t test was applied according to gender variable. One-Way ANOVA test was used in the analysis of the place where the participants' grew up, age, university, department, class variables and LSD test was used to determine the significant difference. Pearson Correlation test was used to determine the relationship between academic self-efficacy sub-dimensions and a significant relationship was found. As a result of the study, while there were no differences in terms of gender, age, university and department variables in academic self-efficacy subscales, a significant difference was found in the place where their families lived and class variables. When the results of the study were evaluated; it can be said that demographic variables are not an important factor in academic self-efficacy of the students

Examination the Effects of Aerobic and Resistance Exercise on Body Compositions of Sedentary Male Individuals

The present study was conducted to determine the effects of 8-week aerobic and resistance training on body composition values of sedentary male individuals. A total of 30 healthy sedentary male subjects volunteered to participate in the study and were divided into two groups randomly: aerobic training group (n = 15, age = 34.0 ± 5.22 years), and resistance training group (n = 15, age = 34.2 ± 6.12). Body heights of the participants were measured and their body compositions body weight (BW), body mass index (BMI), basal metabolic rate (BMR), body fat percentage (BFP), body fat mass (BFM), lean body mass (LBM) were measured with bioelectric impedance analysis (BIA) device, and then evaluated. Their resting heart rates were determined, and maximum heart rates were calculated with the Karvonen formula. The Brzycki Equation was used to predict one-repetition maximum strength. There were statistically significant decreases in BW, BMI, BFP and BFM values of the aerobic training group (p0.05). BW and BMI values of the resistance training group did not show a significant difference in pre-test and post-test (p>0.05). Significant decreases were found in BFP and BFM values (p0.05). In conclusion, it was found out that regular aerobic and resistance training caused positive effects on body composition of sedentary male individuals

The relations between the academic success levels of the boys playing basketball and certain variables

Aim: The aim of this study is to investigate the relation between the academic success levels of the boys playing basketball and certain variables such as age, basketball playing times, the number of the weekly average trainings and motoric skills.Material and Methods: 93 students participated voluntarily in the study from three different sports clubs. The ages in which the participants started basketball varied between 10 and 13, and their durations of weekly trainings differed from each other. The end-of-the-year academic success average points of the participants were considered in determining the academic success levels; and the International Physical Performance Test Profile (IPPTP) (Kamar, 2008) was used in measuring the motoric skills. The issue of whether there was a significant difference between the participants was determined by using the SPSS 21.0 Package Program together with the One-Way ANOVA Test.Results: According to the findings, it was determined that there were no relations between the academic success rates and the basketball playing durations, the number of weekly trainings, and their motoric skills (p>0.05). On the other hand, a statistically significant difference was determined between the age variable and the academic success levels (p<0.05).Conclusions: No significant differences were detected between the motoric skills, number of trainings, starting basketball dates and the academic success levels of the sportsmen who receive basic basketball training (which contribute to the development of motoric skills) with different numbers of weekly training and with different basketball starting dates; while a negative significance was detected between the age variable and academic success

Motor Coordination in Primary School Students: The Role of Age, Sex, and Physical Activity Participation in Turkey

Motor coordination (MC) is an essential skill underpinning precise and controlled movements, contributing significantly to daily functioning and overall performance. The developmental trajectory of MC in children is intricately shaped by a spectrum of factors encompassing age, gender, and physical activity engagement. Delving into the complex interrelation of these variables holds the potential to unravel nuanced developmental trends and offer targeted avenues for interventions aimed at augmenting motor proficiency in the pediatric population. This study aimed to assess the differences in MC of primary school students based on sex, age, and physical activity participation (PAP). A total of 848 students from public primary schools, aged between 6–9 years, including 412 boys and 436 girls. The MC was measured using Körperkoordinationstest für Kinder (KTK3+) test battery, which included Jumping sideways (JS), Balancing backward (BB), Moving sideways (MS), and Eye–Hand Coordination (EHC). One-way multivariate analysis of variance (MANOVA) was used to determine the binary and triple interactions of sex, age, and PAP variables on the MC parameters of the participants. The study revealed that boys aged 6–9 had higher scores than girls on eye–hand coordination (EHC) (p p p < 0.05). The double co-effects or triple co-effects of age, sex, and PAP parameters do not influence the KTK parameters. This study presents evidence supporting sex differences in the motor skills of children within this age range and highlights the potential impact of age and physical activity on motor development

Association of Physiological Performance, Physical Fitness, and Academic Achievement in Secondary School Students

This study aimed to compare the physiological performance and physical fitness based on the academic achievement levels of secondary school students and to explore the effect of gender on the relationship between physiological performance, physical fitness, and academic achievement. In this cross-sectional study, 304 children aged 13–14 years were recruited. To assess physical fitness, students performed a 20 m sprint test, a pro-agility test, a one-mile endurance run/walk test, and a countermovement jump test. At the end of the one-mile endurance run/walk test, the estimated VO2peak value of the participants was calculated. The physiological performance of the students was determined by measuring their resting heart rate and blood pressure. Students were grouped into three categories based on their academic achievement levels. The assessment of academic achievement considered their scores from the previous academic year. The scores were divided into three levels: poor (average score of 69 points or less), average (scores ranging from 70 to 84 points), and good (scores of 85 points or higher). The study revealed a notable disparity among students’ VO2Max measurements based on their academic achievement (F = 8.938, p 2 = 0.056). However, we observed that the group with poor academic achievement displayed lower diastolic blood pressure values than the groups with average and good performances. Finally, no significant gender differences were evident in the relationship between academic achievement and any of the physical and physiological parameters

Effectiveness of Vertical versus Horizontal Plyometric Training on Stretch-Shortening Cycle Performance Enhancement in Adolescent Soccer Players

Abstract: Plyometric exercise is a major tool for improving explosive actions. This study aimed to compare the efficacy of a vertical and horizontal plyometric training program on stretch-shortening performance variables in adolescent soccer players. Thirty-two male soccer players (aged 12.09 ± 0.89 years, with soccer experience 5.37 ± 1.58 years) were divided into horizontal plyometric, vertical plyometric, or control groups. The horizontal and vertical plyometric groups participated in a 6-week training program that was performed twice per week, with a 48-h interval, in conjunction with regular soccer training. The control group participated only in regular soccer training. Vertical jump height, reactive strength index, leg stiffness, ground contact time, standing long jump distance, agility, and 10 and 20 m sprint performances were tested as stretch-shortening performance variables of the participants. Stretch-shortening performance variables were assessed before and after completion of the training program. The results showed that either horizontal or vertical plyometric training had no effect on VJH, RSI, GCT, or Kleg performance (F = 2.14, 1.32, 0.66, 1.03; p &gt; 0.05). Furthermore, there was no effect on SLJ, 10 m sprint, 20 m sprint, or agility performance (F = 2.06, 0.14, 0.06, 0.27; p &gt; 0.05). A 6-week horizontal or vertical plyometric intervention was found to be insufficient to elicit stretchshortening performance enhancement in adolescent male soccer players. Although there was no performance change in any group, it was observed that the players enjoyed plyometric training. Therefore, coaches could safely use plyometric exercises to design enjoyable training programs
