dc.description.abstractRaw acceleration can be used as a proxy measure representing external forces experienced at the hip. Peak vertical acceleration at the hip was measured (ActiGraph GT3X+ - BT) in 30 premenopausal women during common exercises (walking, running, stairs and jumping) and while they went about their normal routine (7 days). Accelerations experienced during running and jumping activities were consistently ≥3.2g, whereas only accelerations during box jumps were greater than the higher recommended threshold of ≥ 4.9g proposed to improve bone mineral density in premenopausal women. Peak jerk experienced during jumping activities was greater than the recommended threshold of 100g/s. The median number of accelerations/day ≥3.2g was 30.4, whereas only 3.5 incidences/day were observed at ≥4.9g. Running and jumping resulted in vertical accelerations that met or exceeded the thresholds proposed to be beneficial for bone, however, participants rarely experienced high magnitude vertical accelerations during daily life.en_US
