FIGURE 3| An example of in vitro mechanical testing for bone samples exposed to various running-specific loading profiles (Loundagin et al., 2018). Left: four distinct loading profiles were applied to bone samples. These four stress loading profiles included: a typical vertical ground reaction force profile for running (raw); an isolated active peak profile (active); an isolated impact peak profile (high impact); and an isolated reduced impact peak profile (low impact). Right: the number of loading cycles until the bone tissue failed for each loading profile. Adapted from Loundagin et al. (2018).

FIGURE 2 | Overview of biomechanical load metrics. The feasibility of measuring various load metrics is indicated on the y-axis, and ranges from limited to the laboratory only, to viable in field environments. The level at which loads act on the musculoskeletal system is indicated along the x-axis, and include the tissue, structural, and whole-body level. Adapted from Verheul et al. (2020).
