Abstract

In order to evaluate the effect of dynamic resistance training (DRT) on lipid profiles, 28 sedentary male smokers (mean age 28 years, 7 months) were randomly placed into a control group (CG) (n = 15) or an experimental group (EG) (n = 13). While the CG took part in no structured exercise throughout the eight-week period, the EG exercised using DRT for the eight weeks (nine exercises were performed at 60% of one repetition maximum, three times per week, non-consecutively) and were monitored for changes in lipid profiles. Although the independent and paired t-tests demonstrated no statistically significant changes in any of the measured lipid profile concentrations, the following changes were observed: decreases in total cholesterol (0.52%) and low-density lipoprotein cholesterol (2.95%), and increases in triglycerides (1.96%) and high-density lipoproteins (4.41%). The lack of statistically significant changes in the individual lipid parameters could not have been affected by diet, cigarettes smoked daily, aerobic fitness and/or body mass, since these parameters did not change significantly from the pre- to post-test measures.


Key words: Cholesterol, male smokers, high-density lipoproteins (HDL), lipids, low-density lipoproteins (LDL), resistance training, triglycerides (TG).
