Spending months aboard the International Space Station (ISS) may sound like a dream, but it comes with a serious downside: muscle and bone loss due to the lack of gravity. To combat this, a Japanese research team led by Dr. Naoto Shiba has investigated a new solution—Hybrid Training Methods. This study was conducted during Expeditions 37/38 and 39/40 and was sponsored by JAXA.
The research focuses on disuse atrophy, a condition where muscles weaken and shrink from lack of use. In microgravity, astronauts don't need to support their own body weight, which leads to significant muscle degradation, especially in the lower body.
Hybrid Training combines traditional resistance training with electrical muscle stimulation. The idea is to simulate the physical stress muscles would experience under Earth's gravity by applying low-frequency electrical currents to targeted muscles while the astronaut performs light resistance exercises. This method not only activates deeper muscle fibers but also enhances overall training efficiency.
The goal of the experiment was to determine whether Hybrid Training could be an effective countermeasure for muscle atrophy in long-duration spaceflight. Initial tests onboard the ISS provided promising results: astronauts showed reduced muscle loss and improved physical function compared to conventional training methods.
This breakthrough doesn’t just help astronauts. It also has applications on Earth, particularly for bedridden patients and the elderly who experience similar muscle degradation. It’s a perfect example of how space research can lead to innovations in human healthcare.
