Definition With physical laws, we try to improve and optimize the individual swimming styles even further. These include static buoyancy, hydrodynamic buoyancy and the various ways of moving around in the water. It uses biomechanical principles and physics. Static buoyancy Almost everyone manages to drift on the water surface without any buoyancy aid. This apparent … Physical laws in swimming
Laws for bodies gliding in water A body moving in water produces various complicated effects that need to be explained to understand swimming. Forces arising in water are divided into braking and driving forces. The total resistance, which counteracts the human body in the water, consists of three forms: The frictional resistance is caused by … Laws for bodies gliding in water | Physical laws in swimming
Body shapes and flow Not the frontal area of a body as previously assumed, but the ratio of frontal area to body length plays the most important role in the resistance in water. This can be illustrated by the following example. If you pull a plate and a cylinder with the same front surface through … Body shapes and flow | Physical laws in swimming
Drive concepts Conventional drive concept: With the conventional drive concept, the body parts used for propulsion are moved in a straight line and in the opposite direction to the swimming direction (actio = reactio). Large masses of water are moved with increasing speed but little propulsion (paddle wheel steamer). Classical drive concept: drive by means … Drive concepts | Physical laws in swimming
What constitutes a good methodological concept? Playing can only be learned by playing. This principle is fundamental to the education of children. Individual technical characteristics such as good throwing power etc. do not yet do justice to the situational characteristics of handball. Children and youths have to interact with fellow players in constantly changing game … The methodological concept of the DHB
Typical errors Typical backhand errors The tennis racket is not held with the backhand but with the forehand gripFollowing: too much palmar flexion in the wrist, overloading of the wrist Result: too much palmar flexion in the wrist, overloading of the wrist Only slight rotation of the upper bodyFollowing: no body tension, shorter acceleration distance, … Typical errors | Backhand ambidextrous
Introduction The backhand, as the basic stroke in tennis, is clearly less popular with players than the forehand. Since the backhand is hit on the left side of the body in right-handed players, it does not allow the player any freedom of stroke arm. “The tennis player stands in his own way when hitting the … Backhand ambidextrous
Definition Today’s dolphin swimming developed in the 1930s when swimmers started breaststroke, simultaneously bringing their arms forward above the water surface. This arm action was combined with a conventional breaststroke. The resulting combination was and is still used today in the German Swimming Association (DSV) as butterfly swimming. In 1965 the technique of dolphin swimming … Dolphin Swimming
