title: [Joint stress in inline skating--a biomechanical study].
abstract: In 8 male subjects we undertook acceleration measurements under standardised conditions at the tibia, the hip and the head. The measurements were performed on a normal flat street as well as on a bicycle route with velocities of 15 km/h, 20 km/h and 25 km/h. Additionally we documented the range of motion at the knee joint. Maximal positive acceleration at the head sensor was 10.75 m/s2 at a velocity of 25 km/h on the bicycle route. At the hip the highest measured value was documented with 15.10 m/s2 at 25 km/h also on the bicycle route. Die maximal tibia acceleration was 55.8 m/s2 at 25 km/h again on the bicycle surface. The amplitude averaged signals showed the highest suppression between tibia and hip.
  
  
  CONCLUSIONS
  Compared to other athletic activities acceleration and joint load in in line-skating is only low.
