Musculoskeletal Outcomes from Chronic High-Speed High-Impact Resistive Exercise

-impulse device evoked large and significant gains in left leg’s calcaneal bone mineral content (+29%) and density (+33%), as well as a significant decline in osteoclast activity ( Caruso et al., 2018 ). Such results hold much promise, as the calcaneus incurs among the largest in-flight losses that are exacerbated by heightened osteoclast activity (Heer et al. 2005; LeBlanc et al., 2007 ). The high-speed high-impact device, called an Inertial Exercise Trainer (IET; Impulse Technologies, Newnan, GA), has a mass sled that traverses its 1.9-m track parallel to the Earth
