Outline of Final Research Achievements

Although it was well documented that tapering has beneficial effects on endurance capacity, the mechanisms have not been well elucidated. Because it was also suggested that biochemical adaptation in skeletal muscle related to endurance capacity, the purpose of this study was to determine the effects of tapering on endurance capacity and biochemical adaptation in skeletal muscle.
This study revealed that two different ways of tapering preserved endurance exercise performance and biochemical adaptation in skeletal muscle of rodents. Furthermore, correlation analysis showed that electron transport chain complex proteins in skeletal muscle were positively correlated with endurance exercise performance.
These results suggested that although exercise amount was temporarily decreased, tapering did not affect endurance exercise performance and biochemical adaptation in skeletal muscle.
