Key result
A repeated bout of eccentric exercise after 2 weeks resulted in no significant changes in muscle force or soreness, despite persistent myofibrillar disruption in 23% of pixels.
Why the study?
Does repeated eccentric exercise induce rapid force recovery independently of cell disruption?
Does repeated eccentric exercise induce rapid force recovery independently of cell disruption?
Rapid force recovery following repeated eccentric exercise appears to be mediated at least in part by neural factors and may occur independently of cell disruption.
No takes yet. Share an insight, caveat, or question.
Rapid force recovery after repeated eccentric exercise may be neural-mediated and independent of myofibrillar disruption; leaves open mechanisms of the repeated bout effect.
Hortobágyi et al. (1998) studied Healthy subjects (implied) (n=12). Repeated eccentric exercise (bout 2) vs. Initial bout of eccentric exercise (bout 1) was evaluated on Force, neural, and morphological adaptations (including muscle strength, EMG activity, and myofibrillar disruption). A repeated bout of eccentric exercise after 2 weeks resulted in no significant changes in muscle force or soreness, despite persistent myofibrillar disruption in 23% of pixels.
