A Comparative Study On Difficulty And Arrangement Of Voluntary Routine Between Chinese And Japanese Youth Trampoline Athletes

Youth Trampoline athletes, as the reserve talents of our country’s trampoline competition, are the hope for this event in our country to maintain strong competitiveness. Japan, as a great power of Asian trampoline, it has cultivated many excellent Trampoline athletes. This dissertation adopts methods of document literature, video recording statistics, comparative analysis, mathematical statistics and so on. The final routines of the age of 11 to 12,13 to 14,15 and above in Chinese and Japanese youth Trampoline athletes are picked as research target to analyse comparatively the types, difficulty and arrangement of these routines. This provides reference for the training and techniques development of our country’s trampoline event. Research results indicate that:1. Difficulty of single movement: the difficulty of two countries’male athletes in 11-12 year-old group is mainly 0.6.0.3-1.3 of two countries maintains 10% or so. The difficulty of two countries’female athletes is mainly 0.6. Our country’s female athletes who chose 1.0-1.3 is higher than Japanese; The higher percentages of two countries male athletes in 13-14 group are 0.6,1.2,1.3 and 1.5, while for female, the higher ones are 0.6,1.2 and 1.3. The percentage of our country’s athletes who chose more difficult movement is higher than Japanese, which has advantage in difficulty; the difficulty of two countries’athletes in 15 and above year-old group is mainly 1.2 and 1.3. The percentage of our country’s male athletes who chose more difficult movements is lower than Japanese. The percentage of our country’s female athletes who chose 1.2-1.6 movements is higher than Japanese.2. Difficulty of routine:the lowest and highest marks of our country’s male Trampoline athletes of 11 to 12 are both higher than Japanese, the highest mark 0.4 higher than Japanese. Difficulty choices of our country’s female Trampoline athletes are uniformly distributed in each mark interval, while Japanese choices are mainly distributed in interval of 7.1-10. The average difficulty of our country’s male Trampoline athletes of 15 is higher than Japanese. Japanese female Trampoline athletes show advantage in the three intervals between 8.1-11.0, while Chinese is mainly in 11.1-12 (40%); Difficulty choices of our country’s male Trampoline athletes of 15 and above shows diversity, while Japanese tends to high difficulty. The difficulty choices’ diversity of Chinese female is less than Japanese, but the average difficulty is higher than Japanese.3. Difficulty of flip:there is no significant difference in the mark intervals and average marks of both two countries of 11-12. Japanese in the higher difficulty interval of 6.6-7.5 is higher than Chinese. Our country has advantage in the high difficulty interval of 6.1-8.0. Male Chinese of 13-14 has advantage in 8.0 and above interval, while Japanese mainly concentrates in 9.0 and below interval. Chinese of 15 and above have advantage in 8.6 interval, while Japanese have advantage in 8.0 and below interval.4. Difficulty of turning:Japanese is higher than Chinese in 0.9 and above, while Chinese mainly choose 0.9 and below. Therefore, we must pay attention the difficulty of turning.5. Difficulty of body posture:Chinese mainly choose straight and pike, while Japanese choose tuck and pike. Chinese choose more difficult body postures than Japanese. We should develop this advantage.6. Chinese common movements:incomplete flip 30/,50o,51o; one flip 40o (<、/)、 41o (<、/), double flip 801o (<)、800o (<)、803o (<); Japanese common movements:one flip 40o (<、/)、42/、44/, double flip 801o (<)、800o (<)、803<、811o.7. Choice of Flip direction:Chinese mainly choose front and back 5:5 to arrange movements; Japanese of 11-12 mainly choose 4:6, while 13-14 and 15 and above choose 5:5.8. Flip round number: it increases with the increase of age. Both two countries of 11-12 mainly choose one round with supplement of two rounds. 13-14 and 15and above mainly choose two rounds.9. Degree of turn:Chinese adopt more no-turn or one turn than Japanese, but Japanese has more turn over 360 degrees than Chinese. Some Japanese chose 900 and 1080 degrees that have never been adopted by Chinese.
