The role of action potential changes in depolarization-induced failure of excitation contraction coupling in mouse skeletal muscle

Excitation-contraction coupling (ECC) is the process by which electrical excitation of muscle is converted into force generation. Depolarization of skeletal muscle resting potential contributes to failure of ECC in diseases such as periodic paralysis, intensive care unit acquired weakness and possibly fatigue of muscle during vigorous exercise. When extracellular K+ is raised to depolarize the resting potential, failure of ECC occurs suddenly, over a narrow range of resting potentials. Intracellular recordings of action potentials (APs) in individual mouse skeletal muscle fibers during depolarization of the resting potential revealed small APs are still generated at resting potentials at which force production has failed. Simultaneous imaging of Ca2+ transients and recording of APs demonstrated failure to generate Ca2+ transients when APs peaked at potentials more negative than -30 mV. An AP property that closely correlated with failure of the Ca2+ transient was the integral of AP voltage with respect to time. Simultaneous recording of Ca2+ transients and APs with electrodes separated by 1.6 mm revealed AP conduction fails when APs peak below -21 mV. We hypothesize propagation of APs and generation of Ca2+ transients are governed by distinct AP properties: AP conduction is governed by AP peak, whereas Ca2+ release from the sarcoplasmic reticulum is governed by AP integral of voltage with respect to time. The reason distinct AP properties may govern separate steps of ECC is the kinetics of the ion channels involved in the different steps of ECC. Na channels, which govern propagation, have rapid kinetics such that propagation is insensitive to AP width (and integral) whereas Ca2+ release is governed by movement of gating charges in Cav1.1 channels, which have slower kinetics such that Ca2+ release is sensitive to AP width (and integral). The quantitative relationships established between resting potential, AP properties, AP conduction and Ca2+ transients provide the foundation for future studies of failure of ECC induced by depolarization of the resting potential.

Rapid recovery by fat- and muscle-depleted Blackpoll Warblers following trans-oceanic migration is driven by time-minimization

Non-stop endurance flights are a defining characteristic of many long-distance migratory birds but subsequent recovery phases are not typically distinguished from fueling phases (collectively 'stopovers'), despite endurance flights inducing marked physiological changes including flight muscle atrophy and gastrointestinal tract reductions. Here, we hypothesize that recovery requires unique behavioral adaptations, leading to departures from the predictions of optimal migration theory for time-minimizing migrants. We predict that recovering birds will 1) select (moist) food-rich habitats on arrival; 2) have slow initial fueling rates due to decreased gastrointestinal capacity; 3) show a negative correlation between stopover duration and arrival condition instead of a negative correlation with fuel deposition rate (FDR); 4) stopover longer than required to store energy reserves for subsequent flights; and 5) show evidence of rebuilding flight muscles. To test these predictions, we studied Blackpoll Warblers Setophaga striata in northern Colombia following trans-oceanic flights >2250 km. Birds selected dry seasonal habitats, despite proximity of moist forests, and among 1227 captured individuals, 14-21% were emaciated and 88% had atrophied flight muscles. We recaptured 74 individuals, revealing net positive mass gains and, contrary to Prediction 2, no evidence for slow initial recovery rates. Contrary to Prediction 3, stopover duration was only weakly correlated with arrival condition and birds with high FDR (4.9% LBM/day) had shorter durations (3 days) relative to birds with slower rates (7 days) - both groups accumulated sufficient fuel to reach non-breeding (over-wintering) grounds 500-1000 km away. Mass increases were largely attributable to fat deposition but some birds improved flight muscle condition (31.9%), consistent with Prediction 5. Together these results reveal a strong selection for time-minimization in the decisions made by Blackpoll Warblers following trans-oceanic flights, likely mediated through advantages to early arrival on non-breeding grounds, contrary to our hypothesis of recovery imposing unique selection pressures.
