Few studies have examined the acute effects of
resistive-type exercise on lipid-lipoprotein profiles. This
study examined the acute effects of a single session of
circuit weight training (CWT) on plasma lipid-lipoprotein
profiles: triglycerides (TG), total cholesterol (TC), high
density lipoprotein cholesterol (HDL-C), low density
lipoprotein cholesterol (LDL-C), and the ratio of TC to
HDL-C. The subjects in the study were 17 healthy, nonsmoking
male university students, ages of 18-25 years, enrolled in
weight lifting classes. Subjects were required to fast
overnight (at least 12 hours) before CWT. Subjects repeated
a four-station weight training circuit three times, with a
resistance determined by their individual 3 repetition
maximum (3-RM). The stations were bench press, parallel
squat, leg extension, and seated row.
Blood samples were drawn from the antecubital vein at
pre-CWT, completion of the 1st and 3rd circuits, and 15 min
post-CWT. All concentrations of plasma lipid and lipoprotein
cholesterol were corrected for plasma volume changes. A
repeated measures ANOVA was used to determine if significant
differences existed among mean values for the dependent
variables (i.e., levels of TG, TC, HDL-C, LDL-C, and
TC/HDL-C ratio at specified time points).
Results of the study indicated that plasma TC and HDL-C
levels were changed significantly during and following CWT.
However, the change was not in the anticipated direction:
Plasma TC and HDL-C levels were lower at completion of the
1st circuit of CWT (p<0.05). The ratios of TC to HDL-C were
changed significantly, reflecting a decrease in HDL-C during
CWT and a slight increase in HDL-C at 15 min post-CWT.
Plasma TG and LDL-C levels were not changed significantly
during CWT or 15 min post-CWT. It was concluded that
apparent changes in lipoprotein patterns occur during
short-term moderate intensity CWT and return to pre-CWT
levels in a relatively short time. / Graduation date: 1991
