Abstract
Key points
- Resistance training is largely underappreciated as a method to improve endurance performance, despite reports showing it may improve mitochondrial function.
- Although several concurrent training studies are available, in this study we investigated the effects of performing a period of resistance training on the performance and molecular adaptations to subsequent endurance training.
- Prior resistance training did not improve endurance performance and impaired most mitochondrial adaptations to subsequent endurance training, but this effect may have been a result of detraining from resistance training.
