Trampoline sport has become an extensive recreational and competitive sport since 2000 Sydney Olympic Games, and has attracted great attention in sport science studies. Purpose: to investigate the effects of an - 8week core muscular strength training on vertical jumping stability during performing trampoline exercise. 15 collegiate students were recruited and divided into three groups including athlete group(AG, N=5), non-athlete group(NAG, N=5), and control group (CG, N=5). EVaRT4.4 Motion Analysis System was used to exam core stability and position offset surface and two-way ANOVA mixed design was used to exam the difference of pre and post training among three groups and Fisher’s Least Significant Different (LSD) test was used for post comparisons and the significant level wasα=.05. Results: 1. an 8-week of core strength training decreased forward and backward displacement during vertical jump significantly (p＜.05), LSD test indicated that AG was superior to NAG and CG; 2. an 8-week of core strength training decreased left and right displacement during vertical jump significantly (p＜.05), LSD test indicated that AG was superior to NAG and CG; 3. an 8-week of core strength training was not found to decrease the stability of area displacement during vertical jump (p＞.05). Conclusion: an 8-week of core strength training increased core stability and enhanced vertical jump consistency during trampoline performance.
Key words：Core strength training, trampoline, vertical jumping stability
