In contemporary research literature, inconsistencies regarding the validity and reliability of different brands of global positioning systems (GPSs) have been reported regarding the positioning of GPS units on athletes. For this reason, the present work investigates the validity and reliability of the measurements of GPS units placed at different l...
This study aimed to determine the relationships of locomotor profile (combination of a player’s maximal oxygen uptake and running economy)—measured by the final velocity attained at 30-15 Intermittent Fitness Test (VIFT) and the anaerobic speed reserve (ASR)—with the body composition, countermovement jump (CMJ), sprinting performances, and change-o...
The aim of this study is to examine how physical performance has changed after 15 weeks (109 days) long-term absence of organized training in youth soccer players imposed by the stay at home orders. A total of sixty-eight young male soccer players from different age categories (U15, U16, U17 and U19) voluntarily participated in the prospective coho...
The purpose of this study was two-fold: (i) analyze the variations of locomotor profile, sprinting, change-of-direction (COD) and jumping performances between different youth age-groups; and (ii) test the interaction effect of athletic performance with playing positions. A cross-sectional study design was followed. A total of 124 youth soccer playe...
In the last decade, in parallel with the growing interest and development in the health and fitness sector in the world and in our country, the interest in the concept of “coaching”, which is used to guide individuals about exercise for various reasons, has increased. Thus, according to the American College of Sports Medicine, both personal fitness...
The purpose of the present study was to investigate the relationship between repeated sprint ability, isokinetic knee strength and anaerobic performance in futsal players. 13 male futsal players (age: 24.38± 2.46 years) participated in this study voluntarily. Repeated sprint ability (RSA) with and without change-of direction (COD) were determined b...
The aim of this study was to evaluate the relationship between vertical jump and change of direction ability with different agility test performances of soccer players. Twenty-six male soccer players (age=9.4±0.5 years, height=138.8±8.7 cm, weight=31.1±5.6 kg, body mass index=16.0±2.0 kg.m-2) from U9-U10 age categories of a first division team in T...
The aim of this study is to evaluate anaerobic power values and repeated change-of-direction ability of futsal players. Twelve elite futsal players (age: 27,25 ± 4,55, height: 172,58 ± 5,74, weight: 75,00 ± 9,69) participated in the study voluntarily. Repeated Change-of-Direction (RCOD) test developed by Wong. et al. (2012) was applied to determine...
This study aimed to analyse technical and tactical aspects of Turkish Futsal National Team (TFNT) which participated in UEFA Futsal EURO 2012 for the first time. Technical and tactical data collected via video display of the matches played by the TFNT in the championship were analyzed through the video analysis program “eAnalyze Soccer Voice,” and...
The aim of this study is to determine the changes in heart rate (HR) and lactate levels (LA) in elite futsal players throughout a game. Eight elit futsal players (24±2,8 year, 174,33±4,33 cm, 71,488±3,31 kg, 9,31±2,78 % fat mass) with a mean playing experience of 3,4 years participated in this study voluntarily. Heart rate was recorded for five tim...
The aim of this study was to compare the repeated straight-line sprint (RSL) and repeated shuttle sprint (RSS) performances of futsal players. Twelve male futsal players (age: 24.45±2.69 years) participated in this study voluntarily. Repeated sprint abilities were determined by 6x25m repeated straight line sprint test and 6x (2x12.5m) repeated shut...

Today, the use of technology is increasing rapidly. This increase is becoming much more accessible, especially through mobile devices. On the other hand, the need for instant monitoring and continuous assessment of the performance of athletes in professional sports has become a must for fitness professionals and coaches. From this point of view, the aim of this study is to analyze the performance test and measurement methods, which have become economically and easily measurable via smart phones, together with their validity and reliability in the scientific field.
