Aims:
Use the MARES device to quantify the time course of changes in muscle strength and performance of crewmember volunteers during six-month ISS missions. Establish baseline strength and performance capabilities of each participating crewmember from two pre-flight test sessions, track changes from that baseline during three in-flight test sessions, and track recovery to baseline levels during five post-flight test sessions.

Evidence or Risk Characterization
Description:
Study scope and 'n' was reduced, so the deliverable was not addressed.
Time course of neuromuscular function
1. Measurement of isometric and isokinetic strength of the ankle plantar flexor and knee flexor and extensor muscle groups using standard techniques programmed into the MARES device.
2. Measurement of dynamic motor control performance during a set of position-matching tasks performed with and without external MARES-imposed joint torque loads,
3. Measurements of the balance and potential adaptation of flexor and extensor motor (EMG) activations during strength and motor control performance testing.
