Background Jump landings have been quantified as a stimulus for bone health programs, however they may not be suitable for some populations. Currently, studies quantifying alternative types of lower body exercises are limited and no studies have quantified upper body exercises for inclusion in bone health programs. This study sought to quantify and determine the reliability of a heel drop and push up drop exercise to determine whether they achieve magnitudes and rates of force previously shown to improve bone mass among premenopausal women. Methods Twenty women (Mean ±SD: 41.7 ±5.6 y; 68.2 ±10.6 kg; 165.0 ±7.6 cm) performed heel drops and push up drops on a Kistler force plate. Results The magnitude (4.9 BW’s) and rate (357 BW∙s-1) of force for the heel drop, exceeded previously determined thresholds (>3BW’s and >43 BW∙sˉ1) and the push up drop exceeded (147 BW∙sˉ1) the rate of force threshold. The heel drop force data demonstrated moderate to good (0.45 to 0.80) reliability, and the push up drop demonstrated moderate to excellent (0.50 to 0.84) reliability. Significantly (p<0.001) greater ground reaction force variables were observed in the heel drop compared to the push up drop (ES= 2.60 to 4.96). Conclusion The heel drop and push up drop could provide a unique osteogenic training stimulus for at risk populations and be incorporated into exercise programs to improve bone health. Longitudinal osteogenic training studies are needed to provide the dose-response relationships associated with bone remodelling and insight into the design and prescription of bone health programs.
