The purpose of the present study was to examine effects of slope and height of starting block on swimming start performance. Total 6 six competitive swimmers (Mage = 17.9years, SD = 1.18; MBW = 82.65kg, SD = 1.38; Mheight = 180.83cm, SD = 2.93) participated in this study. 3-dimensional motion analysis and 2-dimensional dynamic data analysis techniques used to evaluate block phase of swimming start. Kinematic and kinetic data obtained by using four different block settings. Multiple two-way within subject ANOVAs conducted to investigate main and interaction effects of block slope and block hight on kinetic and kinematic variables. Results indicated that, center of mass distance to the front edge, movement and block times, maximum horizontal force, average and maximum vertical forces, vertical impulse, take-off vertical velocity were significantly affected by block slope. In conclusion, results of this study indicates that block slope is the primary determinant of variations in block phase and substantially affects vertical components. On the other hand, horizontal impulse and horizontal take-off velocity, which are accepted as decisive variables of block phase remained unchanged. This study provides evidence of how block settings can affect swimming start performance.

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...
Effect of Foundation Soil Stiffness on the Seismic Performance of Integral Bridges Dicleli, Murat (Informa UK Limited, 2011-05-01) In this study, the effect of foundation soil stiffness on the seismic performance of integral bridges (IBs) is investigated. For this purpose, nonlinear structural models of a two-span TB with four different foundation soil stiffness types (loose, medium, medium-dense and dense sands) are built. In the nonlinear structural models, nonlinear soil structure interaction including free-field effects is considered. Then, the nonlinear time history analyses of the TB models are conducted using a set of ground mot...
Effects of Small-Sided Games Training versus High-Intensity Interval Training Approaches in Young Basketball Players Arslan, Ersan; Kilit, Bulent; Clemente, Filipe Manuel; Murawska-Cialowicz, Eugenia; Soylu, Yusuf; Söğüt, Mustafa; AKÇA, FIRAT; Gokkaya, Mine; Silva, Ana Filipa (2022-03-01) This study aimed to investigate the effects of the 6-week small-sided games training (SSGs) vs. high-intensity interval training (HIIT) on the psychophysiological and performance responses, and technical skills of young basketball players. Thirty-two male players (age: 14.5 +/- 0.5 years of age) were randomly divided into SSGs group (n = 16) and HIIT group (n = 16) training methods thrice per week for 6 weeks. The players in the SSGs group performed two 5-8 min of 2 vs. 2 with 2 min rest periods, while the ...
Effects of self-paced high-intensity interval training and moderate- intensity continuous training on the physical performance and psychophysiological responses in recreationally active young adults Soylu, Yusuf; ARSLAN, ERŞAN; Söğüt, Mustafa; Kilit, Bulent; Clemente, Filipe (2021-01-01) This study aimed to compare the effects of 8-week self-paced high-intensity interval training (HIIT) vs. self-paced moderate-intensity continuous training (MICT) on the physical performance and psychophysiological responses of young adults. Twenty-eight recreationally active young adults (age: 21.1 +/- 1.6 years) were randomly assigned to either the self-paced HIIT (n = 14) or the MICT (n = 14) group training protocol. The HIIT consisted of two 12-24 x 30 seconds of high-intensity runs interspersed by 30 se...
Fluid migration and rheological properties of different origin G-class cements in oil well drilling applications Kök, Mustafa Verşan (2018-01-01) In the first part of this study the effect of free water on fluid migration potential is tested for different cement slurries using standard API G-class quality tests. Static gel strength analyser is also used to measure the static gel strength of cement slurries. Three different class G type cement samples were tested according to their free fluid values which are 2.5%, 5%, 3.12% respectively, and it is found that A-type cement, with lowest free fluid content, has the lowest potential for fluid migration. ...
