Adaptive Training Recommendations for Improved Physical Performance

In this study two different training strategies are compared; one is adaptive where the training is adjusted up or down on a daily basis to better match the recovery status (readiness) of the subject. The other strategy is static, i.e. no changes are made depending on readiness level. Instead the subjects in the static group are encouraged to perform the prescribed training. The training intervention will last for 8 weeks. Thorough physiological tests will be performed pre and post the training intervention together with muscle biopsies for assessment of mitochondrial function.

Inclusion Criteria: * Training history of at least two running sessions per week (5km +) the last 6 months * No chronic diseases * Able to perform maximal exercise * Having used a smart watch for training frequently during the last 3 months * Willing to use wearable technology (Oura ring, continuous glucose monitor, running GPS watch) Exclusion Criteria: * Heart, lung or metabolic disease * Recurrent running injuries * Not willing to use wearable devices * Performing a subtantial amount of non-running exercise training
