title: [Fast Response Training in Youth Soccer Players].
abstract: BACKGROUND
  Injuries of the knee and ankle joint are a serious ongoing problem in soccer. Although there is a variety of prevention programmes, a significant reduction of severe knee injuries has not been observed. Therefore, current strategies for diagnostics and training need to be re-evaluated.
  
  
  OBJECTIVE
  Our study aimed to test a totally new intervention strategy (fast response training on the SpeedCourt). The efficiency of this method was evaluated with youth soccer athletes.
  
  
  METHODS
  24 young male class A athletes (mean age 18.0 ± 0.7 years) of a local soccer team underwent SpeedCourt training for 7 weeks (1 training session per week = TS) during the regular season of competition. TS contained life-kinetic elements (time of exercise: 15 - 30 seconds, break: 2 minutes) and included a warm-up phase (15 minutes) and fast response training on the SpeedCourt (30 minutes). The players were tested on the SpeedCourt with different tests (Counter Movement Jump (CMJ), shuttle run, tapping, 10-second sprint) before and after the training programme.
  
  
  RESULTS
  The univariate single-factor analysis of variance showed significant improvements in all test parameters (η(2)> 0.10). The range varied between η(2) = 0.106 (time of ground contact right leg) und η(2) = 0.730 (reaction time right leg). We did not find any relevant correlations between the tests and parameters. The number of injury-related accidents involving the lower extremities was reduced by about 50 % during defined periods of time.
  
  
  CONCLUSIONS
  Our data revealed that training with fast responses at the SpeedCourt system clearly improved speed and speed strength performance of young soccer athletes, which is remarkable given the low intensity of influences (one TS per week). The increase in performance was accompanied by a significant reduction of the injury rate.
