With the fast developing pace of the situation and the increasing requirements for undergraduates＇ English level, the available Syllabus is obviously far from satisfaction. This paper, from six perspectives, expounds the inadequacies and drawbacks of the Syllabus. It points out that college English teaching and the Syllabus need reform and should keep pace with the times.展开更多

Methods： Seventy-four male collegiate soccer players took part in the study and were randomly assigned to FIFA 11＋ with acute vibration group （FIFA ＋ WBV）, FIFA 11＋ with isometric squat group （FIFA ＋ IS） or a control group consisting of the F1FA 11＋ alone （Con）. The warm-up consisted of the FIFA 11＋ and was administered to all participants. The participants in the acute vibration group were exposed to 30 s whole body vibration in squat position immediately post warm-up. The isometric group completed an isometric squat for 30 s immediately post warm-up. Results： RSI significantly improved pre- to post-intervention amongst FIFA ＋ WBV （p 〈 0.001） due to a decrease in contact time （p 〈 0.001） in comparison to FIFA ＋ IS and Con, but 505 agility was not affected. Conclusion： The results of this study suggest the inclusion of an acute bout of WBV post FIFA 11＋ warm-up produces a neuromuscular response leading to an improvement in RSI. Future research is required to examine the exact mechanisms behind these improvements amongst other populations and over time course of the performance.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
