Response Of Low-density Lipoprotein Cholesterol To Three Modes Of Exercise Training

Abstract

Previous research on the favourable decrease in low-density lipoprotein cholesterol has mainly focused on aerobic training (AER). PURPOSE Thus, the aim of the study was to investigate the effect of 16 weeks of AER, dynamic resistance training (DRT) and a combination of the two modalities in the form combination training (COMB) on LDL-C. METHODS A quantitative, experimental, comparative, research design making use of a pre-test, treatment period and post-test was used. Subjects were divided into one control group (CG) and three experimental groups: AER, DRT and COMB. RESULTS Dependant t-tests revealed that in the present investigation, the CG demonstrated a mean 2.300% non-significant increase in serum LDL-C post-experimentally (from a mean of 4.121 mmol/l to a mean of 4.209 mmol/l) (p = 0.754; p ≤ 0.05). In the exercising experimental groups, the DRT demonstrated a 7.000% non-significant decrease from a pre-test value of 2.859 mmol/l to a post-test value of 2.621 mmol/l (p = 0.116). Conversely, however, The AER demonstrated a 20.130% decrease from 3.644 mmol/l to 2.868 mmol/l (p = 0.002) while the COMB similarly demonstrated a 24.870% significant decrease from a pre-test value of 4.391 mmol/l to a post-test value of 3.234 mmol/l (p = 0.001) over the 16-week treatment period in sedentary male smokers. CONCLUSION Only AER and COMB was effective at reducing LDL-C in sedentary male smokers.
