What the study is about

This study aims to determine how flywheel-based inertial training (FIT) implemented according to principles of velocity-based training (VBT) and High-Intensity Interval Training (HIIT) affects disuse-induced physical de-conditioning including loss of voluntary muscle strength, aerobic capacity, and balance regulation.

Being studied: velocity-based FIT (VBFIT); No Exercise

Conditions: Muscle Atrophy; Muscle Weakness
