The effect of exercise and fish oil supplements on the blood lipid levels of the hamster
The effect of aerobic exercise and fish oil supplements
on plasma lipid parameters was investigated in the hamster.
The hamsters were fed a basal hypercholesterolemic purified
diet (0.1% cholesterol, 15% fat) to elicit an elevated lipid
response. Fifty-six hypercholesterolemic hamsters were
divided into four groups: control, swimming (trained up to
one hour every other day), daily fish oil supplementation
(.35g/kg/day omega-3), and a swimming/fish oil combination.
The effect of these treatments on plasma TC, TG and pooled
samples of plasma HDL-C, HDL2â C, LDL-C and VLDL-C was
studied over 12 weeks. All hamsters had a significant
increase in body weight. Feed intakes increased at 6 weeks
and then declined over the second 6 weeks, but remained
above the beginning levels.
