[Biomechanics in sports].

Sports are often practised nowadays in balance for a non challenging profession or as means to counteract stressful life style. This desirable and reasonable development calls however for a critical assessment of biomechanical factors contributing to stress and admissible load of the human locomotor system. Considerate training renders excessive strain of the skeleton, cartilage and vertebral column virtually impossible. In view of the time required for adaptive processes this statement has to be combined with an appeal for appropriate training to those seeking compensation in physical exercise. Especially young people and middle-aged persons experiencing so called midlife-crisis tend to practise unbalanced and excessive sportive activity.
