Purpose: To probe the differences of time structure and utility rate between the new and conventional badminton rules. The analysis also provides coaches with the consultation on the application of training and matches. Methods: To observe, record, and analyze 26 singles that were held in new or conventional rules by the IBF during around 2006. The t-test and z-test were using to analyze the time structure of matches and utility rate of techniques respectively. Results: The effect on time structure of singles between new and conventional rules are: the average stroke time in new rules was significant shorter for men's singles but longer for women's singles (p<.05), men's average rest interval in new rules was significant longer (p<.05), women's average time per game in new rules was significant longer (p<.05). The utility rates of some techniques were significant differences between new and conventional rules. Conclusions: According to men's average stroke time was reduced after applying the new rules, the development of tactical skill in speedy attack still remains the important tendency in men's singles. However, defence remains primary tactic in women's singles because of the increase in women's average stroke time. The work-rest interval structure of 1:2.7 in men's singles and 1:2.3 in women's singles and men's average time per game was 19'49” implied that the appropriate training interval, intensity, and quantity could be arranged. The different utility rate of techniques provides the tendency of key techniques development and the reference of training and match application.
