Suggests propagation failure drives maximal SSC fatigue; leaves open applicability to submaximal or clinical exercise contexts.
Fatigue from short-lasting maximal stretch-shortening cycle exercise appears primarily driven by impaired high-frequency action potential propagation rather than contractile failure.
Strojnik et al. (1998) studied Healthy volunteers (n=12). Maximally intensive stretch-shortening cycle exercise (drop jumps) vs. Baseline was evaluated on Neuromuscular fatigue markers including blood lactate, creatine kinase, and twitch torque. Maximally intensive stretch-shortening cycle exercise significantly increased blood lactate (P<0.001) and decreased single twitch peak torque (P<0.05), indicating neuromuscular fatigue.
