COLOR 20 JUNE - 7 JULY 1996 STS078-430-009 JOHNSON SPACE CENTER, HOUSTON, TEXAS STS-78 ONBOARD VIEW --- Astronaut Richard Linnehan, mission specialist, performs a test on his leg using the Torque Velocity Dynamometer (TVD). Dr. Thirsk was measuring changes in muscle forces of the leg in this particular view. The TVD hardware is also used to measure arm muscle forces and velocity at the bicep and tricep areas. Crew members for the mission performed all experiment protocols prior to flight to develop a baseline and will also perform post-flight tests to complete the analysis. Additionally, muscle biopsies were taken before the flight and will be conducted after the flight.
