Muscle Matters: Bridging the Gap Between Terminology of Age-Related Muscle Loss and Exercise Interventions

Araújo, C. G. S. & Tou, N. X. . J. Aging Phys. Act. 33, 209–211 (2025). Key Points Age-related loss of muscle is associated with adverse health outcomes leading to disability and higher risk of mortality. Various criteria used to define sarcopenia have involved not only muscle mass but also muscle function. Age-related muscle loss terminology should follow specification of …

Physiological Resilience: What Is It and How Might It Be Trained?

Jones, A. M. & Kirby, B. S. Scand. J. Med. Sci. Sports 35, (2025). Physiological resilience has recently been recognized as an additional factor that influences endurance exercise performance. It has thus been incorporated into a modified, contemporary version of “the Joyner model” which acknowledges that start-line values of V̇O 2 max, efficiency or economy, and metabolic thresholds are prone …

Reversible reduction in brain myelin content upon marathon running

Ramos-Cabrer, P., Cabrera-Zubizarreta, A., Padro, D., Matute-González, M., Rodríguez-Antigüedad, A. & Matute, C. Nat. Metab. 7, 697–703 (2025). Here we use magnetic resonance imaging to study the impact of marathon running on brain structure in humans. We show that the signal for myelin water fraction—a surrogate of myelin content—is substantially reduced upon marathon running in specific brain regions involved in …
