In this case report, we examined the performance changes during tapering in two badminton athletes (one male and one female) who advanced to the finals at the World Championships (WC). Furthermore, the significance of a resistance priming session implemented during tapering was discussed. Both athletes participated in a pre-competition training camp in Japan before the WC. A resistance priming session was scheduled one and two days before the WC for the male and female athletes, respectively. Non-countermovement jump (NCMJ) and countermovement jump (CMJ) were measured using a linear position transducer to monitor performance responses from the camp to the WC final. The baseline of the jump performance was given from 15 days (male) and 151 days (female) prior to the WC final. In the male athlete, the mean power of NCMJ decreased 7 days before the finals. This result may be attributed to accumulated fatigue caused by high volume training in the training camp and the short taper period as well as long travel to the host city. In the female athlete, the mean velocity and power of CMJ were the same as baseline before the semi-final. That is, the quarter-final match, where she competed for 85 minutes-the longest game time among the previous matches, may have affected her fatigue. Regardless of these findings, both athletes showed higher jump performance than at baseline just before the final because the matches likely played a role in tapering. In addition, both athletes recorded their personal best jump height just before the final. These findings may indicate that jump performance can be an indicator of tapering and peaking. The findings of this report also demonstrate that athletes may maintain resistance training adaptations by taking advantage of resistance priming for peaking and tapering.
