Buoyancy
Buoyancy the force acting perpendicular to the direction of flow or in the opposite direction of gravity upon an object which in subjected to a flow of a fluid or a gas around it. In sport buoyancy plays an important role especially in water sports and aeronautic sport, but also in ski jumping and in track and field (javelin and discus throw). In swimming the utilization of buoyancy is specifically taught in beginner’s classes in order to achieve a horizontal body position in the water. Various additional buoyancy aids such as belts and cork boards are also used. The amount of buoyancy depends on the characteristics of the flowing medium (e.G. Salt concentration and flow of the water, wind force and direction). In the dead sea, e.G. Buoyancy in high enough (25% salt concentration) to make resting on the water without any movement possible. Buoyancy in water or air represents a primary movement experience for the human being. (H.Haag &g. Haag, dictionary, 2003, 101 p.)
