Strength training improves cholesterol level (a little)
The women trained three times a week and each session consisted of a full-body workout. The women did chest press, lat-pulldown, shoulder-press, seated-rows, leg-abductions, leg-adductions, chest-flies, de leg-press, leg-curls and leg-extensions. The women did 3 sets of 8 reps for each exercise; the last set each time was to failure.
A control group of twelve women didn't train.
A single training session had no effect on the triglyceride or cholesterol concentration in the blood, but after 12 weeks the LDL cholesterol concentration (LDL = bad), the triglyceride concentration (triglycerides = even worse) and the non-HDL cholesterol (non-HDL cholesterol = all bad things together) concentration had decreased by 23, 16 and 20 percent respectively.
According to cardiologists, the chance of a heart attack or other "nonfatal coronary heart eventĒ decreases by 4.4 percent for every mmol per litre decrease in the LDL cholesterol concentration.
In comparison, sponsored studies show that statins can reduce the LDL cholesterol level so much that the chance of a nonfatal coronary heart event decreases by thirty percent.
But still, a decrease of 3.4 percent through strength training is of course better than none at all. In addition, the researchers hope that the positive cardiovascular effects of strength training may increase in the longer term.
The women in the group that trained gained strength, but changes in body composition were not statistically significant.
"Furthermore, these results provide support for the use of whole body resistance training in obese, postmenopausal women as a non-pharmacological approach for the reduction of lipid and lipoprotein-cholesterol concentrations."
