HR-150

In spite of advances made in using resistive exercise to preserve bone and muscle in the hip, lumbar spine, and thigh regions, astronauts still suffer from muscle atrophy in the muscles of their calf. On earth, physical therapists and trainers recommend heel raise exercises to strengthen these muscles. This model of the heel raise exercise should provide NASA exercise physiologists with the data required to better prescribe exercise to protect the strength of these muscles.

As an improvement to the HERO device, NASA developed the Hybrid Ultimate Load Kit (HULK) that enables the subject to perform squats, lunges, and dead lifts. HULK loads the subject via a bar across the shoulders. Due to the nature of the OpenSim environment, and because all of the load is borne at the lumbar spine and in the legs, for simplicity the model does not include the subject's arms.
