真实和坦诚

我们曾经勾画了最初的自我评估过程。我要再次强调在评价自己的强项和弱点上,真实和坦诚是一切的基础。有了对自我的诚实,你才能准确地找到需要改进和提高的地方。     

穿越与防穿越

网球运动需要改变

今天的网球比赛早已不同以往,在最近的印象里,似乎没有哪一周我们不会听到选手受伤,或者旧伤复发的消息。相反,在冠军巡回赛（即元老赛）中,那些退役的名将们周游世界,在友谊赛和表演赛中奋力拼搏,使观众开心。

夏日天堂

既然大型运动会都喜欢每四年举办一次,那么热爱运动的人也喜欢用四年来计算自己的寿命,世界杯总提醒你去回忆四年前的事情,而不是去年,你会记清啤酒的颜色,和周围朋友红肿的双眼。虽然网球是如此不同,它总是在年复一年,但幸运的是,总有其他运动来给它设置一个大的周期,     

Sporting Events Organized in Venice: Male Boating and the Amazing Case of Women's Rowing Contests

In Venice between the middle ages and the modern era, a number of cultural entertainments as well as sporting contests and popular games were performed to celebrate the carnival and other important religious and civil events; these might include state visits of important people from abroad. Under control of the government, the organizers and participants of these events were of both noble and modest origins. Among them were the rival Castellani and Nicolotti groups who were common people living in the two main districts of Venice, and the well off young members of the Venetian aristocracy enrolled in numerous Compagnie della Calza (Companies of the Hosiery). The Castellani and Nicolotti regularly competed in popular games, such as the Gioco del Ponte, the Forze d'Ercole, the Moresca dance and in different kinds of boat races; the aristocrats enjoyed to personally practice sports such as hunting, fishing, horse riding and ball games. In addition, the latter collaborated in important state events leading to feasts and theatrical performances, and organized popular games, mock naval battles and regattas together with those in power. Among the regattas, the female rowing contests that started to take place in the middle ages was a unique, as, in general, the Venetian women were only allowed to be the gracious spectators in the numerous festivities organized for important visitors celebrating the glory of Venice. Drawing on both ancient and modern sources the paper will mainly focus on the less familiar Companies of the Hosiery and their contribute in the organization of mock naval battles and regattas till 1797, when Venice definitively lost its independency under Napoleon the First. Special stress will be given to the humble female rowers who were able to overcome the usual gender barriers training and racing for their own pleasure and amusement; they gave birth to an early model of female emancipation.

对网球衍生而来的短网与软网项目的分析

本文通过文献资料法、对比分析法和逻辑分析等方法,对网球、短式网球和软式网球的场地、器材、比赛规则和方法及发展现状做出详细的分析。短式网球和软式网球是从网球运动中衍生出来的运动项目,这三种不同的运动项目具有颇多的相似之处,但富有不同的内涵。网球的发展相当完善,网球人口众多。短式网球比较特殊,主要针对青少年儿童,软式网球发展不乐观。     

Tennis

The study investigated differences in the one‐ (SH) and two‐handed (DH) backhands when hit flat, across‐court (AC) and down‐the‐line (DL), and with heavy topspin DL (TDL). The ability to disguise each of these backhands when hitting the above strokes was also assessed. Eighteen college‐level male tennis players, identified as having a high performance topspin SH (n = 6) or DH (n = 12) backhand drive, participated in the study. Players were required to hit three AC, DL and TDL backhands from the baseline with their preferred technique, while being filmed with two high‐speed video cameras operating at 200 Hz. The highest horizontal velocity backhand for each stroke was analysed. Results indicated that the sequential coordination of five body segments (hips, shoulder, upper arm, forearm, and hand/racquet rotations) was required for the execution of the SH stroke. The same number of segments were generally coordinated in the DH stroke (hips, shoulders, and varying degrees of upper arm and forearm rotations followed by hand/racquet movement). Mature players produced comparable racquet horizontal velocities 0.005 s prior to impact using either the SH or DH backhand technique. The SH backhand was characterised by a more rotated shoulder alignment than the DH stroke (SH: 119.1°; DH: 83.4°) at the completion of the backswing. At impact the ball was impacted further in front (SH: 0.59 m; DH: 0.40 m) and a similar distance to the side of the body (SH: 0.75 m; DH: 0.70 m). Players using the DH backhand technique delayed the horizontal acceleration of the racquet towards the ball (SH: 0.13 s; DH: 0.08 s prior to impact) and thus were capable of displaying a similar hitting motion closer to impact than players with a SH technique.     

Tennis

This study investigated the effect of the larger diameter (Type 3) tennis ball on performance and muscle activation in the serve. Sixteen male advanced tennis players performed serves using regular size and Type 3 tennis balls. Ball speed, surface electromyography, and serve accuracy were measured. There were no significant differences in mean initial serve speeds between balls, but accuracy was significantly greater (19.3%) with the Type 3 ball than with the regular ball. A consistent temporal sequence of muscle activation and significant differences in mean activation of different muscles were observed. However, ball type had no effect on mean arm muscle activation. These data, combined with a previous study, suggest that play with the larger ball is not likely to increase the risk of overuse injury, but serving accuracy may increase compared to play with the regular ball.     

场地类型

草地球场是历史最悠久的场地类型。草地的特点是球落地后与地面的摩擦小,球的弹跳低,反弹速度快,因此被称为发球上网型选手的天堂。草地球场对草的特质、气候要求极高,维护费用昂贵,之后逐渐被硬地所取代。在大满贯创办初期,四大满贯都属于草地球场,法网在1928年改为红土,美网和澳网之后都改为硬地,目前,知名的草地比赛几乎全部集中在英国。土场的特点是球落地
