It has been shown that high levels of high-density lipoprotein (HDL) @entity165 and low levels of low-density lipoprotein (LDL) @entity165 are associated with health maintenance in older @entity1 , but the few studies that have examined the relationship between exercise and plasma lipoprotein levels in this elderly population have been equivocal. In addition, there are no studies that examine the plasma lipoprotein response of two different types of exercise in a group of active but nonexercising @entity1 . Thus, the effects of exercise training on plasma lipoprotein levels in elderly @entity1 remain unclear. The purpose of this research was to examine the effects of endurance and resistance exercise on plasma lipoprotein levels in elderly @entity1 who were active but nonexercising prior to the study. A total of 45 healthy, active @entity1 , aged 70-87 years, were randomly assigned to either an @entity411 ( @entity411 , 76 +/- 5 years, n = 15), @entity3013 ( @entity3013 , 73 +/- 3 years, n = 15), or control (C, 74 +/- 5 years, n = 15) group. The @entity411 group walked 3 days a week at 70% heart rate reserve. The duration on day 1 was 20 minutes, and it was increased by 5 minutes each day until subjects were walking for 50 minutes (week 3). The exercise training session for the @entity3013 group consisted of one to three sets of eight repetitions of eight different exercises at an eight repetition maximum; the C group maintained normal activity. Weight and diet were unchanged across groups. The exercise interventions lasted 10 weeks. Blood samples were obtained from all subjects at week 0 and week 11. Training resulted in a significant decrease in 1-mile walk times and heart rate at completion of the walk for the @entity411 group and a significant increase in eight repetition maximum of all @entity3013 exercises. Both @entity411 and @entity3013 groups experienced increased HDL @entity165 and decreased triglycerides at week 11 compared with week 0. There were no positive changes in control lipoproteins. Both @entity1674 and the total @entity165 to HDL ratio increased significantly while total @entity165 , HDL @entity165 , and LDL @entity165 remained unchanged. The @entity3013 group also had significantly lower LDL @entity165 and total @entity165 compared with controls at week 11. Both @entity3013 and endurance training resulted in favorable changes to plasma lipoprotein levels for elderly @entity1 in only 10 weeks. The fact that this occurred without concurrent changes in weight or diet is an indication that high-intensity exercise alone can be used to modify lipoproteins in populations of healthy elderly @entity1 .
