摘　　要：运用文献资料、录像观察、数理统计等研究方法,以参加里约奥运会、第44届、第45届世锦赛和伦敦奥运会双杠决赛选手为研究对象,从"时间特征"视角,对当代世界双杠成套动作发展趋势进行探讨。结果表明:获得奖牌的运动员的动作难度已突破7分,继续提升D分的空间相对较小;从双杠项目成套动作的内容上看,支撑摆动的动作正在逐步减少,而短半径回环和悬垂大摆动作迅速增加,但挂臂摆动动作大多仅是为了满足编排要求,其构成比例接近为3∶3∶3∶1;获得奖牌选手主要选用短半径回环和悬垂大摆动作,且以倒立姿势结束,完成动作的时间效应明显提高;继续提高动作的稳定性和准确性,或将成为取得优异成绩的决定因素。Taking the finalists in the Rio Olympic Games and 44th and 45th world championships and the London Olympic Games as research subjects, this paper makes a study on the trend of set movements of contemporary world parallel bars from time characteristics with the research methods of literature, video observation and statistical analysis. The results show that if the difficulty degrees of the medalists reach 7 points and above, it will leave little space for their improvements to D level. It also finds that for the set movements, the support swings are gradually reducing while the short radius loopbaek and drape swing are rapidly increasing; meanwhile, most of the movements of upper arm swings are arranged to meet the arrangement requirements with correspondingly approximate proportion of 3：3：3：1. Besides, the medalists mainly choose the short radius loopback and drape swing, and dismount with handstands, which increase the time effect of movement completion. Therefore, continuing improvement of the stability and accuracy of the movement may be the determining factor for the excellent performances.
