摘　　要：Purpose:In order to satisfy the requirements of Chinese Para seated cross-country skiers special training for Double poling scientifically,and the individualized strength training of Paralympic athletes,this study aims to explore the effect of the full-dimensional servo-driven intelligent training system on para cross-country skiers’strength training.Methods:12 Para seated cross-country skiing athletes were included(6 males and 6 females:LW10.5-LW12),4 weeks of training of the Double poling based on the centripetal isotonic mode of the fulldimensional servo-driven intelligent training system,the special strength quality indicators include the speed and power of the Double poling in the centripetal phase.The SPM1d paired-sample t-test was used for statistical analysis of each index before and after training.Results:After 4 weeks of special movement training through the full-dimensional servo-driven intelligent training system,the speed and power of the Double poling of 12 seated cross-country skiers were significantly improved compared to before training.In the Double poling period,the speed index of female athletes increased significantly in the 92%-100% stage,and the male athletes in the 20%-23% and 72%-73% stages.The power index of female athletes increased significantly in the 17%-18%,21%~30% and 70%~82% stages,and the male athletes in the 49%-58% and 91%-100% stages.Conclusion:The full-dimensional servo-driven intelligent training system can significantly improve the special strength quality index of Para seated cross-country skiers’Double poling techniques and enhance the special ability on snow.In addition,the system can meet the personalized and specialized training needs of disabled athletes to a great extent,monitor and feedback training data in real-time,and further reduce the risk of sports injuries.
