Expedition 11 Flight Engineer John L. Phillips works at the Canadarm2 controls in the Destiny Laboratory while conducting an experiment session with the Foot/Ground Reaction Forces During Spaceflight (FOOT) experiment.
Phillips, who also serves as the NASA ISS science officer on the International Space Station, is wearing a pair of cycling tights outfitted with sensors that measure his joint angles, muscle activity and forces on the feet during a typical day on the Space Station.
FOOT could help explain the reasons for bone and muscle loss during space flight and aid in the design of exercise countermeasures. This experiment also has significance for understanding, preventing and treating osteoporosis on Earth.
