Jump-landings that supersede bone health threshold requirements for premenopausal women

Abstract
Osteoporosis is a disease characterized by a reduction in the density and quality of bone leading to a weakness of the skeleton and associated increased risk of fracture [1]. The most common type of osteoporosis is termed primary osteoporosis and includes both postmenopausal and age-related osteoporosis, which involves the structural deterioration of bone and increased porosity leading to increased fragility [2] (Figure 1).
