The use of bioelectrical impedance analysis for estimating the body composition of various fish species
… estimate body composition is lacking. Proximate analysis is the most dependable and accurate method for estimating internal composition, but it is lethal, time consuming, and expensive. Recent research has shown bioelectrical impedance analysis (BIA) to be an effective method for estimating …

Use of bioelectrical impedance analysis (BIA) to predict water and energy content of juvenile Rainbow Trout (Oncorhynchus mykiss)
… of fish. Bomb calorimetry and proximate analysis are currently the most dependable and accurate methods to estimate energy content and body composition. However, bioenergetic studies that employ the traditional methodology necessitate the killing of fish to determine physiological …

Bioelectrical impedance analysis as a predictor of fish health and energy content in juvenile rainbow trout (Oncorhynchus mykiss)
… using bomb calorimetry or proximate composition analysis; however, both of these methods necessitate sacrificing the fish in order to obtain accurate data. This has led to research into novel non-lethal methods of analyzing fish tissue so as to determine the body composition and health condition …

Omega-3 fatty acid supplementation to improve body composition and perceived stress in collegiate athletes.
… oil. Baseline and post-study measures included Bioelectrical Impedance Analysis (BIA), Omega-3 Index, and Perceived Stress Score (PSS). Results: No statistically significant changes were observed in either group after 8 weeks. Conclusions: FO n-3 supplementation did not significantly impact body …

The influence of silvicultural manipulations on plethodontid salamanders
… for plethodontid salamanders. I found that bioelectrical impedance analysis (BIA) is likely not suitable for use with plethodontid salamanders and mass divided by snout-to-vent-length is likely a superior estimate to tail width divided by snout-to-vent-length. These findings further our …

Statistical modelling of body composition in children and their parents
… novel methods of determining body composition, bioelectrical impedance analysis (BIA) and bony frame, in addition to anthropometry (body mass index in particular) and skinfolds. Parental body composition is thought to be influential on their children's body composition. Such influence does not …

Childhood obesity treatment: integrating mobile health technology into a paediatric obesity service
… In Study 3, body composition was estimated with bioelectrical impedance analysis (BIA) and dual x-ray absorptiometry (DXA) and linear regression analyses were used to estimate the extent to which each methods predicted change in IS. Study 4 describes the development of the Temple Street W82GO …
