Only a few studies which have investigated body components of youth soccer players, and studies that look at electrical characteristics used by rheobase and chronaxie as well as body components are even scarcer. Therefore, we feel that there is a need for a study investigating objective clinical analysis of the body components (body structure and body composition) and electrical characteristics of both youth soccer players and non-athletes. Sixty subjects participated in our study, comprising of thirty youth soccer players and thirty non-athletes. The Inbody 520 was used to measure and analyze body composition and the Duo 500 was employed to measure electrical characteristics. It was observed that the soccer players showed markedly lower total impedance compared to the non-athletes. In both legs, it was particularly noted that there were significant differences between the right and left sides. The soccer players showed a higher skeletal muscle mass and lean/ideal lean × 100% compared to the non-athletes. Furthermore, the soccer players had a lower rheobase and higher chronaxie. A comparison of the genders showed a similar pattern. In this study, we were able to separate the differences in body components and electrical characteristics between the subject groups using a systemic approach. Future studies on diverse types of athletes would contribute further to the development of clinical physiotherapy and sports rehabilitation.展开更多

Since players are the centered component of this approach, players＇ perception can provide useful information for coaches in order to enhance cognitive learning of game play and improve game performance. Thus, the purpose of this study was to determine the players＇ perception for implementing the game-centered approach in coaching. Approximately 30 min of interviews with open-ended questions were conducted with five female collegiate soccer players. The game-centered approach helped participants to recognize their weaknesses and their strengths, to think more tactically and to adapt their performance from practices to competitions. Players were encouraged to tactically analyze their performance, emphasize cognitive learning of game play, and construct game knowledge. The cognitive learning helped players to easily transfer their game performance into competitions. Additionally, there was a positive impact on the players＇ motivation while they experienced enjoyment, challenges, and teamwork. Cognitive learning of game play, the performance adaptability for competitions, as well as the improving players＇ motivation was supported during the game-centered approach. Results provided helpful information for coaches to improve the effectiveness of practices which are truly useful to competitions.展开更多

This consideration is part of our study, which aims to evaluate and quantify the difference between the workload of an amateur footballer and an elite one. All this is allowed by match analysis made by GPS evaluation method for amateur and video tracking for elite. The examined teams were playing in 7th Italian league, and we used 10 GPS to track 6 games, 5 for each team. For every team and every game were analysed a forward, a central midfielder, a wide midfielder, a central defender and a full back （Age 25.3 ＋ 4.2, Weight 74.5 Kg a： 5.3, Height 1.76 cm ＋ 5.2）. In our study, we used a 20 Hz GPS （thanks to Advanced Research Group in Sport, School of Health and Sport Science with K-Sport Universal, Italy） to detect performance data, and then we compared the outcome with matches performance data from elite players gather from scientific literature. Data analysis shows that elite players reach higher values in almost all parameters taken into account. In particular, they obtained higher value in meters per minutes, High Speed Distance （〉 16 Km/h）, High Metabolic Power Distance （〉 20 W/Kg） and in high and very high and acceleration （2 m/s, 3 m/s, 〉 3 m/s） and deceleration （-2 m/s, -3 m/s, 〉 -3 m/s）. This study can be useful to select and catalogue player performance model, in order to better understand the real value of a player, and to help coaches and teams to identify talent, at least in physical values.展开更多

To date, only two scientific publications have attempted to review the main findings of studies published in this area. However, one of them was published about 20 years ago, when women＇s football was still in its infancy and there were only a few studies to report on. The other review was more recent. Nonetheless, its main focus was on the game and training demands of senior elite female players. Thus, information on female footballers of lower competitive levels and younger age groups was not included. Consequently, an updated review is needed in this area. The present article therefore aims to provide an overview of a series of studies that have been published so far on the specific characteristics of female football players and the demands of match-play. Mean values reported in the literature for age （12-27 years）, body height （155-174 cm）, body mass （48-72 kg）, percent body fat （13%-29%）, maximal oxygen uptake （45.1-55.5 mL/kg/min）, Yo-Yo Intermittent Recovery Test Level l （780-1379 m）, maximum heart rate （189-202 bpm）, 30 m sprint times （4.34-4.96 s）, and counter- movement jump or vertical jump （28-50 cm） vary mostly according to the players＇ competitive level and positional role. There are also some special considerations that coaches and other practitioners should he aware of when working with female athletes such as the menstrual cycle, potential pregnancy and lactation, common injury risks （particularly knee and head injuries） and health concerns （e.g., female athlete triad, iron deficiency, and anemia） that may affect players＇ football performance, health or return to play. Reported mean values for total distance covered （4-13 km）, distance covered at high-speed （0.2-1.7 km）, average/peak heart rate （74%-87%/94%-99% HRmax）, average/peak oxygen uptake （52%-77%/96%-98% VO2max）, and blood lactate （2.2-7.3 mmol/L） during women＇s football match-play vary according to the players＇ competitive level and positional role. Methodological differences may account for the discrepancy of the reported values as well. Finally, this review also aims to identify literature gaps that require further scientific research in women＇s football and to derive a few practical recom-mendations. The information presented in this report provides an objective point of reference about player characteristics and game demands at various levels of women＇s football, which can help coaches and sport scientists to design more effective training programs and science-based strategies for the further improvement of players＇ football performance, health, game standards, and positive image of this sport.展开更多
