Abstract: BackgroundLower limb muscular strength is a well-known predictor of all-cause mortality and physical function in adults.Assessment of lower limb muscle strength using the criterion isokinetic dynamometer method is expensive and often not accessible in clinical or field settings.Accessible alternatives to the dynamometer would allow for broader screening of the risk and consequences of frailty, including falls and fractures.Recently, 3-dimensional optical (3DO) scanners have been investigated as an alternative to manual anthropometry and other body composition measures for health assessment.3DO wholebody scans have the potential for predicting strength due to their ability to produce over 200 variables of total and regional anthropometric measurements such as limb length and girth.Our previous studies have found only modest 3DO anthropometry and isokinetic knee extension; female: R 2 =0.24,RMSE=31.28,male: R 2 =0.34,RMSE=54.51 (1).Bioelectrical impedance (BIA) is another standard clinical tool for estimating body composition, such as skeletal muscle (SMM), phase angle (PhA), which could be a potential complementary tool to 3DO given its ability to give valid estimates of muscle strength. ObjectiveOur objective is to identify the optimum estimate of lower limb strength using a combination of 3DO anthropometry measures and BIA.
