Agnirva Space Premier League - Expedition #31464: Boosting Muscle Health in Space: The Power of Neuromuscular Electrical Stimulation

Microgravity affects every system in the human body, but muscles are among the most visibly impacted. To address this, the European Space Agency (ESA) launched a new initiative: the use of Neuromuscular Electrical Stimulation (NMES) to support astronauts’ muscle health.

Led by Dr. Alessandra Bosutti of the University of Trieste, this study aims to complement regular exercise routines aboard the ISS with NMES—a technique that uses electrical impulses to stimulate muscle contractions. This approach is often used in physical therapy and rehabilitation on Earth, especially for patients with limited mobility.

In the context of spaceflight, NMES offers several advantages. By activating muscle fibers through targeted impulses, it helps maintain muscle tone and strength, even when traditional exercise is limited. This is particularly important on longer missions, where maintaining peak physical condition is essential for safety and mission success.

Astronauts involved in Expeditions 71 through 74 applied NMES protocols regularly while aboard the ISS. Scientists then evaluated their muscle mass, strength, and overall physical health before, during, and after the missions. Preliminary findings suggest that NMES is an effective supplement to the standard exercise regimen in space.

Not only does this technology promise to make space travel safer, but it also holds great promise for Earth-based applications. People recovering from surgery, the elderly, and individuals with disabilities could benefit from improved NMES protocols based on space research.

By blending advanced technology with space science, this experiment underscores how innovations from orbit can improve lives on Earth.
