Microdosing of Flywheel Training: Effects of Low Versus High Training Frequency on Muscle Mass, Strength, and Power.
International Journal of Sports Physiology and Performance May 4, 2026 Sergio Maroto-Izquierdo, Marina Gómez, Susana López-Ortiz et al.
Microdosing flywheel resistance training—five short daily sessions per week—improved muscle thickness, fascicle length, and fascicle angle in the thigh muscles of active individuals, while once-weekly training with the same total volume did not. Both regimens similarly increased leg strength and jump performance. However, the microdosing group reported much lower perceived exertion and muscle soreness throughout the six-week program. The findings suggest that spreading resistance training into small daily doses can enhance muscle architecture and reduce fatigue, offering a practical alternative for athletes with congested schedules or people in rehabilitation.
