Heeney points out that the association between hemoglobin levels and weight may also have to do with disease severity. “Children with mild SCD make more hemoglobin and don't need to put as much energy into making RBCs. That energy can then go towards growth and weight gain.

GGT may elevate because of increased synthesis or accelerated release from damaged or dead liver cells. It seems to primarily indicate continuous, rather than episodic, heavy drinking, although a few moderate drinkers also produce elevated levels of GGT (Gjerde et al.

Most research on the age– performance issue has tested for linear relationships, meaning that as age increases, performance consistently increases or decreases. However, if the relationship is actually curvilinear, this would mean the relationship has a different form than simply higher or lower with increasing age.

It is shown that the decrease in muscle mass relative to total body may be wholly responsible for the age-related decreases in basal metabolic rate. Energy consumption by physical activity also decreases with atrophic changes of skeletal muscle. Thus, energy requirement in the elderly decreases.
