Treadmill exercise within lower body negative pressure protects leg lean tissue mass and extensor strength and endurance during bed rest. [PDF]
, 2016 Leg muscle mass and strength are decreased during reduced activity and non-weight-bearing conditions such as bed rest (BR) and spaceflight. Supine treadmill exercise within lower body negative pressure (LBNPEX) provides full-body weight loading during BR
