Through the repeated bout effect (RBE), adaptations occur, then damage and weakness are attenuated following a subsequent bout. However, it is unclear whether the RBE protects peak power output. We investigated the influence of the RBE on power production and estimated fatigue- and damage-induced neuromuscular impairments following repeated high-intensity eccentric contractions. Twelve healthy adult males performed 5 sets of 30 maximal eccentric elbow flexions and repeated an identical bout 4 weeks later. Recovery was tracked over 7 days following both bouts. Reduced maximum voluntary isometric contraction torque, and increased serum creatine kinase and self-reported soreness indirectly inferred muscle damage. Peak isotonic power, time-dependent measures\u00a0\u2014 rate of velocity development (RVD) and rate of torque development (RTD)\u00a0\u2014 and several electrophysiological indices of neuromuscular function were assessed. The RBE protected peak power, with a protective index of 66% 24 h after the second eccentric exercise bout. The protection of power also related to preserved RVD (R<jats:sup>2<\/jats:sup> = 0.61, P &lt; 0.01) and RTD (R<jats:sup>2<\/jats:sup> = 0.39, P &lt; 0.01). Furthermore, the RBE\u2019s protection against muscle damage permitted the estimation of fatigue-associated neuromuscular performance decrements following eccentric exercise. <\/jats:p><jats:p> Novelty: The repeated bout effect protects peak isotonic power. Protection of peak power relates to preserved rates of torque and velocity development, but more so rate of velocity development. The repeated bout effect has little influence on indices of neuromuscular fatigue.
