Although the eccentric phase is frequently the focus of flywheel training, not all exercises, users, or training loads achieve eccentric overload. Consequently, practitioners should define this resistance method as ‘flywheel resistance exercise or training’ instead of ‘eccentric overload’.

Reliable flywheel training exercise outputs are contingent upon the user’s effort, training experience (i.e., familiarization), moment of inertia (kg.m2) selected, and the mechanical characteristics of the devices used.

Practitioners can use flywheel resistance training as a valid method to develop chronic morphological adaptations in both sporting and healthy male or female populations.

Practitioners can use flywheel resistance training as a valid method to increase mechanical power and jump performance of male and female populations. Enhancements can be seen with interventions that are short and consisting of lower weekly training frequencies.

Practitioners can use flywheel resistance training as a valid method to increase athletes’ ability to perform sport-specific acceleration and deceleration actions.
