Physical activity and high -density lipoprotein cholesterol in sedentary male smokers

High-density lipoprotein (HDL) with its cardio-
protective effects has provided remarkable
optimism to the ever-increasing incidences of
coronary artery disease. Therefore, the aim of this
randomized, comparative, research trial was to
determine whether endurance exercise training,
weight training and/or a combination of aerobic and
weight training can be utilized in the management
of high-density lipoprotein cholesterol (HDL-C).
Subsequent to the 16-week intervention period,
dependant t-Tests revealed that the non-exercising
and weight training groups demonstrated non-
significant mean 1.3% (p = 0.754) and 11.1% (p =
0.069) increases in fasting serum HDL-C,
respectively. Conversely, there was a significant
increase in HDL-C following the 16 weeks of
endurance training (p = 0.003) and combination
training (p = 0.005) (22.4% and 37.9%,
respectively). Further, Spearman’s rho indicated no
correlations between HDL-C and BMI (r = -0.131),
percentage body fat (r = - 0.141), cholesterol intake
(r = - 0.026) and total fat intake (r = - 0.239). The
absence of changes in these inter-correlations
indicated that changes in these parameters had no
effect on the HDL-C. On the contrary, moderate
correlations were established between HDL-C and
number of cigarettes smoked daily (r = - 0.344) and
intake of saturated fat (r = - 0.317) indicating that
exercise effect on these variables could have
indirectly contributed significantly in altering HDL-
C in the endurance and combination training
groups. As such, endurance and combination
training can be utilized as an effective method in the
management of HDL-C in sedentary male smokers.
