WRunning is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground. This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
WAn aid station is a temporary facility established to provide supplies to endurance event participants or medical first aid and provisions during major events, disaster response situations, or military operations.
WBiathlon orienteering or orienteering shooting is a multisport consisting of shooting and orienteering. The sport is organized internationally by the International Biathlon Orienteering Federation (IBOF), and is mainly practiced in the Nordic countries as well as a few other European countries. Competitions are organised in Denmark by Danish Military Sports Association (DMSA), in Sweden by the civilian Swedish Multisport Association and in Finland by the Finnish Reservist Sports Federation (FRSF).
WFootspeed, or sprint speed, is the maximum speed at which a human can run. It is affected by many factors, varies greatly throughout the population, and is important in athletics and many sports, such as association football, rugby football, American football, track and field, field hockey, baseball, and basketball.
WGlobal Running Day is a day that celebrates the sport of running. It is held annually on the first Wednesday of June. Participants of all ages and abilities pledge to take part in some type of running activity by submitting their names through the Global Running Day website. Global Running Day 2019 took place on June 5.
WIlka Groenewold is a German television presenter and athlete.
WPace, also called rhythm or tempo, is the rate of activity or movement, such as in running or the flow of events in an entertainment piece.
WA pacemaker or pacesetter, sometimes informally called a rabbit, is a runner who leads a middle- or long-distance running event for the first section to ensure a fast time and avoid excessive tactical racing. Pacemakers are frequently employed by race organisers for world record attempts with specific instructions for lap times. Some athletes have essentially become professional pacemakers. A competitor who chooses the tactic of leading in order to win is called a front-runner rather than a pacemaker.
WPronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three cardinal plane components: subtalar eversion, ankle dorsiflexion, and forefoot abduction, these three distinct motions of the foot occur simultaneously during the pronation phase. Pronation is a normal, desirable, and necessary component of the gait cycle. Pronation is the first half of the stance phase, whereas supination starts the propulsive phase as the heel begins to lift off the ground.
WTransponder timing is a technique for measuring performance in sport events. A transponder working on a radio-frequency identification (RFID) basis is attached to the athlete and emits a unique code that is detected by radio receivers located at the strategic points in an event.
