Purpose: To probe the differences of time structure and techniques using rate between the new and conventional badminton rules for men's and women's doubles. The analysis also provides coaches with the consultation on training and matches. Methods: To observe, record, and analyze 22 doubles that were held in new or conventional rules by the IBF. The t-test and z-test were using to analyze the time structure of matches and techniques using rate respectively. Results: The average stroke time in new rules was significant shorter for men's doubles. The average rest interval in new rules was 1:3.7 and 1:2.0 for men's and women's double, respectively. It was significant longer for both men's and women's doubles. The average time per game in new rules was 16'58” for men's doubles and 18'17” for women's doubles. It was shorter but not significant different for both men's and women's doubles. Some of the techniques using rate had significant differences between new and conventional rules. Conclusions: According to the time structure of doubles in new rules, the intensity and anaerobic training should be emphasized to adapt the characteristic of energy supply. The key techniques for doubles are not only serves and smashes, but also lobs, net balls, and chops. The tactics of fast attack should be the development trend for men's doubles. Moreover, the tactics of multivariable attack and counterattack from defense were developed for women's doubles because of the maturity of defense.
