quantification of precision error (PE) is frequently done by calculating differences in same-day repeat assessments of body composition ( Hangartner et al., 2013 ; Hind et al., 2018 ) using least significant change (LSC) values, this fails to account for biological variability in the absence of controls, and

corresponding least significant change (LSC) were calculated using standardized protocols as recommended by the International Society for Clinical Densitometry ( Hangartner et al., 2013 ). This was done in a population of resistance-trained athletes using the same Hologic Discovery A scanner used in this study

Bone mineral density (BMD) loss is a medical concern for individuals with spinal cord injury (SCI). Concerns related to osteoporosis have lead researchers to use various interventions to address BMD loss within this population. Whole body vibration (WBV) has been reported to improve BMD for postmenopausal women and suggested for SCI. The purpose of this case study was to identify the effects of WBV on BMD for an individual with SCI. There were three progressive phases (standing only, partial standing, and combined stand with vibration), each lasting 10 weeks. Using the least significant change calculation, significant positive changes in BMD were reported at the trunk (0.46 g/cm2) and spine (.093 g/cm2) for phase 3 only. Increases in leg lean tissue mass and reduction in total body fat were noted in all three phases.

for least significant change for DXA previously proposed in rugby union athletes ( Barlow et al., 2015 ). It is well established that skinfold-based regression equations are not an effective way of estimating absolute body composition in rugby union ( Zemski et al., 2018 ) or other sports ( Doran et

analysis estimated whole-body fat mass (in percentage and kilograms) and lean soft tissue mass (LTM, in kilograms; which excludes bone mineral mass). Coefficient of variation values for all whole-body measurements were <2.0%, and the least significant change values were calculated as 0.2, 1.1, and 1.0 kg
