Resistance training and changes to plasma lipoproteins in postmenopausal women

Objectives. The main purpose of this study was to assess the effect of progressive resistance training on the blood lipid profile in postmenopausal women. Methods. Twenty-six female participants aged 50 - 75 years were selected from the population of Grahamstown, South Africa. All participants were previously sedentary and possessed at least one lipid profile abnormality but were otherwise healthy. Pretests included a sub-maximal stress test, stature, mass, central and limb girths as well as an oral glucose tolerance test (OGTT) and a total blood lipid profile. Participants took part in a 24-week progressive resistance training programme, consisting of three supervised sessions per week, each lasting 45 minutes. Participants were not permitted to lose more than 10% of initial body mass during the 24-week study. All pre-test measures, excluding the stress test and the OGTT, were repeated every 4 weeks for the duration of the study. Results. Body mass, body mass index and waist-to-hip ratio did not change. Girth measures at mid-humerus, chest, waist, hip, mid-quadricep and mid-gastrocnemius all decreased significantly (p
