Galileo Research Facts No. 105: Can Galileo Training decrease Spinal Excitability even in micro-gravity?

The same study as in #GRFS104 did not only assess muscle activation (EMG) but also Spinal Excitability (H/M Ratio) during Galileo Training in micro-gravity (parabolic flights). The study was performed during the 14th parabolic flight campaign of the German Space Agency (DLR) in 2009, which was already the second campaign Galileo Training was used in. During parabolic flight, the airplane (Airbus A300 Zero-G) follows the trajectory of a thrown ball. During this path a 20 second period of micro-gravity which is repeated about 30 times per flight.

The Spinal Excitability is the sensitivity of the reflexes reacting on an external stimulation. This study shows like others (#GRFS74, #GRFS37) that Galileo application at high frequencies (25Hz) can significantly decrease Spinal Excitability (in this case within 20 seconds even at micro gravity during parabolic flights).
