Can Strength Exercise Affect the Muscle Oxygen Saturation Response?

Miranda-Fuentes et al. (2021)

Resumen

This 2021 study by Miranda-Fuentes et al. investigated how different resistance training protocols impact muscle oxygenation. Using Near-Infrared Spectroscopy (NIRS), the researchers found that while short-duration strength exercise does not significantly change overall oxygen saturation (SmO2), it significantly increases local hemoglobin concentration (Hgb), indicating a robust hemodynamic compensation.

El equilibrio de oxígeno del músculo permanece relativamente estable durante esfuerzos breves de alta intensidad debido a un rápido aumento en la entrega de sangre al tejido activo. Esta investigación aclara cómo el cuerpo gestiona la oferta y la demanda metabólica.
