Gross motor coordination in junior tennis players

The purpose of this study was twofold: (1) to determine the gross motor coordination performance levels of junior tennis players and (2) to analyse the effects of age and gender. Participants were junior male (n=50) and female (n=51) tennis players aged 6-14. Korperkoordinationstest fur Kinder (KTK) was used to assess the gross motor coordination of the participants. Results revealed that none of the participants performed lower than normal level in motor coordination. Besides, 40.6% of the participants performed above normal level. No gender differences were found on all subtests of KTK and also on total motor quotient. Although older players performed better on each test than their younger counterparts for the raw scores, no significant age effect was observed on motor quotient scores among different age groups.


A Comparison of Serve Speed and Motor Coordination between Elite and Club Level Tennis Players
Söğüt, Mustafa (Walter de Gruyter GmbH, 2017-01-01)
The purpose of this study was to compare the serve speed and motor coordination of elite and club level junior tennis players aged 11-14 years. Participants (n=35) were assigned to one of the two groups according to their experience, weekly training volume and competition level. Serve speed was assessed with a sports radar gun. Motor coordination was evaluated by means of the Korperkoordinationstest fur Kinder. The main results revealed that serve speed and motor coordination performance levels of the elite...
A Multivariate Approach to Assessing Anaerobic Power Following a Plyometric Training Program
Koçak, Mehmet Settar (Ovid Technologies (Wolters Kluwer Health), 1997-01-01)
This study used a multivariate approach to assess anaerobic power in 20 athletes and 20 nonathletes undergoing 6 weeks of plyometric training, and 20 controls. A 3 x 2 mixed model MANOVA was done to analyze the pre-and posttest scores of vertical jump, 50-m dash, and Margaria-Kalamen stairclimbing test. The Group x Test interaction was significant (p < 0.001). Both groups that underwent plyometric training improved significantly (p < 0.01) on all tests of anaerobic power. Of the dependent measures, the Marg...
Physical Activity Level Sport Participation and Parental Education Level in Turkish Junior High School Students
Koçak, Mehmet Settar; KİN İŞLER, AYŞE; ÇİÇEK, ŞEREF (Human Kinetics, 2002-01-01)
This study examined physical activity level, sport participation, and parental education level in 333 female and 359 male Turkish junior high school students. Student's physical activity level, sport participation, and parental education level were determined by a questionnaire with three sections. Independent samples t-test results revealed higher physical activity level and chi-square results indicated higher sport participation for boys when compared with girls. In addition significant negative correlati...
Evaluation of body composition using three different methods compared to dual-energy X-ray absorptiometry
Duz, Serkan; Koçak, Mehmet Settar; Korkusuz, Feza (Informa UK Limited, 2009-01-01)
In this study, we compared the simple methods of skinfolds, ultrasound, and bioelectrical impedance analysis (BIA) against the standard of dual-energy X-ray absorptiometry (DEXA) in the assessment of body fat in normoactive Turkish male and female university students. We wished to develop new regression equations to more accurately predict percent body fat from skinfolds and ultrasound for this group of individuals. One hundred and four male (age 22.22.5 years; height 1.770.06 m; mass 74.910.4 kg) and one h...
Impact of Social-Ecologic Intervention on Physical Activity Knowledge and Behaviors of Rural Students
CENGİZ, CEVDET; İnce, Mustafa Levent (Human Kinetics, 2014-11-01)
Background: The purpose of the study was to determine the effects of a social-ecologic intervention on health-related fitness (HRF) knowledge and behaviors of students (n = 62) living in rural areas. Methods: A prepost test control group design was constructed. In addition, qualitative data were collected by focus group discussions in the experimental group. Physical activity environment of a middle school was changed based on the social-ecologic model (SEM) with a focus on intrapersonal, interpersonal, com...
