Question: Information: - Cross-country skiing is a form of skiing where skiers rely on their own locomotion to move across snow-covered terrain, rather than using ski lifts or other forms of assistance. Cross-country skiing is widely practised as a sport and recreational activity; however, some still use it as a means of transportation. Variants of cross-country skiing are adapted to a range of terrain which spans unimproved, sometimes mountainous terrain to groomed courses that are specifically designed for the sport. - Skeleton is a winter sliding sport in which a person rides a small sled, known as a skeleton bobsled (or -sleigh) down a frozen track while lying face down (prone), as well as the name of the sled employed. Unlike other sliding sports of bobsleigh and luge, the race always involves single riders. Like bobsleigh, but unlike luge, the race begins with a running start from the opening gate at the top of the course. The sport (and the sled) were named from the bony appearance of the sled. - Bobsleigh or bobsled is a winter sport in which teams of two or four teammates make timed runs down narrow, twisting, banked, iced tracks in a gravity-powered sled. The timed runs are combined to calculate the final score. - Horst Koschka ( born September 8 , 1943 in Altenberg ) is a retired East German biathlete . He represented the sports club Sportvereinigung ( SV ) Dynamo / SG Dynamo Zinnwald . - Chess is a two-player strategy board game played on a chessboard, a checkered gameboard with 64squares arranged in an eight-by-eight grid. Chess is played by millions of people worldwide, both amateurs and professionals. - SG Dynamo Zinnwald is a sector of SV Dynamo located in Altenberg, Saxony. Sometimes referred to as SSV Altenberg, it was founded in October 1992. Sports covered. The main sports covered by the club are biathlon, bobsleigh, luge, mountain biking, and Skeleton (sport). This is due to the terrain surrounding Altenberg and the bobsleigh, luge, and skeleton track located in the area. Secondary sports covered by the club are alpine skiing, chess, dance, cross-country skiing, football (soccer), nordic combined, and table tennis. - Table tennis, also known as ping pong, is a sport in which two or four players hit a lightweight ball back and forth across a table using a small bat. The game takes place on a hard table divided by a net. Except for the initial serve, the rules are generally as follows: players must allow a ball played toward them to bounce one time on their side of the table, and must return it so that it bounces on the opposite side at least once. A point is scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. Spinning the ball alters its trajectory and limits an opponent's options, giving the hitter a great advantage. - The Sportvereinigung Dynamo ("Dynamo Sports Association") was the sport organization of the security agencies (Volkspolizei, Ministry for State Security and customs) of former East Germany. The sports club was founded on 27 March 1953 and was headquartered in Hohenschonhausen in East Berlin. From the date of its inception until 23 November 1989 the president of the SV Dynamo was Erich Mielke, who was also the Minister of State Security. Dynamo was created in accordance with the multi-sports club model developed in the Soviet Union and adopted throughout Eastern Europe. From the beginning it had an overtly political as well as sporting agenda and its many successes were always portrayed as a triumph of the GDR state. During the German reunification in 1989 the SV Dynamo was liquidated. At its height the association had a membership of over 280,000 active members. Athletes of the association enjoyed considerable success both in national and international competitions, winning for example more than 200 olympic medals. After the German reunification the systematic doping of Dynamo athletes from 1971 until 1989 was revealed in German media reports. The systematic doping of athletes was done under the supervision of the Staatssicherheit and with full backing of the government. - The biathlon is a winter sport that combines cross-country skiing and rifle shooting. - Nordic combined is a winter sport in which athletes compete in cross-country skiing and ski jumping. Nordic combined at the Winter Olympics and the FIS Nordic Combined World Cup are ongoing. - Alpine skiing, or downhill skiing, is the sport or recreation of sliding down snow-covered hills on skis with fixed-heel bindings. It is characterized by the requirement for mechanical assistance getting to the top of the hill, since the equipment does not allow efficient walking or hiking, unlike cross-country skis which use free-heel bindings. It is typically practiced at ski resorts which provide services such as ski lifts, artificial snow making and grooming, first aid, and restaurants. Back-country skiers use alpine skiing equipment to ski off the marked pistes, in some cases with the assistance of snowmobiles, helicopters or snowcats. Alpine skiing has been an event at the Winter Olympic Games since 1936 (except for the 1940 games). - A luge is a small one- or two-person sled on which one sleds supine (face up) and feet-first. Steering is done by flexing the sled's runners with the calf of each leg or exerting opposite shoulder pressure to the seat. Racing sleds weigh 2125 kilograms (4655lb) for singles and 2530 kilograms (5566lb) for doubles. Luge is also the name of an Olympic sport. Lugers can reach speeds of 140km per hour (87mph). Manuel Pfister of Austria, reached a top speed of 154km per hour (95.69mph) on the track in Whistler, Canada prior to the 2010 Winter Olympics. Lugers compete against a timer, and on artificial tracks they are timed to a thousandth of a second, making luge one of the most precisely timed sports in the world. The first recorded use of the term "luge" is 1905, from the Savoy/Swiss dialect of French "luge" meaning "small coasting sled", and is possibly from a Gaulish word with the same root as English sled.
