Concurrent training resulted in blunted lower-body strength adaptations in males, but not in females.

For training status, untrained but not trained or highly trained endurance athletes displayed impaired improvements for maximal oxygen consumption with concurrent training.

Most concurrent training studies include relatively untrained participants, and highly trained athletes are under-represented in the literature.

Training status should be considered both in terms of strength and endurance training status and can be evaluated according to the mentioned classification framework.
