These fat and lean mass variables were log transformed and converted to an age (in 1-mo categories) and sex standardized z scores for each of the separate clinic visits (9 or 11).
The numerical behaviors using different variable sets, including the so-called natural and mass variables, are investigated.
COM was derived using standard sex body segment length and mass variables.
Diurnal cortisol levels before treatment were also positively correlated with change in the corresponding fat mass variables (rs = 0.64, P < 0.01 and rs = 0.69, P < 0.01, respectively).
Mean latencies to approach the food in the spatial foraging task were analysed using a LME with nutritional treatment (variable = categorical, two levels, LH and HH) and body mass (variable = continuous) as fixed factors and natal cage as random factor.
Despite controversies with regard to BMI and lean mass and bone mass, as independent variables, and also limiting the use of BMI as an indicator of fat mass, studies indicate an association between BMI and the physical performance in the elderly people [ 1, 22].
As the mass is variable, and the derivative of the mass is directly considered in the traditional Lagrange equation, the expression of generalized force is complicated.
However, there is a progressively increasing body of evidence that scaling relationships of metabolic rate vs. body mass and population density vs. body mass are variable and deviate from their respective theoretical values of 3/4 and −3/4 or −2/3.
Results from an analysis of variance (ANOVA) derived from multiple regression models with mass dimorphism and male body mass as independent variables, and brain size and testis size as dependent variables, indicated that the level of male competition for mates had a significant association with brain size but not with testis size.
By properly selecting the geometry of the rocking surface, the VFRB isolation frequency, which is independent of the super-structural mass, becomes variable and can be designed to meet the required specifications.
