Response of oxidative stress markers and antioxidant parameters to an 8-week aerobic physical activity program in healthy, postmenopausal women Export

@article{citeulike:4680384, abstract = {The aim of the study was to assess the influence of an 8-week aerobic physical activity program on oxidative stress markers, antioxidant parameters, and selected metabolic parameters in healthy, postmenopausal women. The study was carried out in a group of 41 healthy women (mean age 65 years) participating in an 8-week cycle ergometer physical workout of moderate intensity. Before and after completing the training program, the following parameters were assessed: total antioxidant status (TAS) and concentrations of thiobarbituric acid reactive substances (TBARS) in plasma, serum levels of antibodies against oxidatively modified low-density lipoproteins (LDL) (oLAB), serum concentrations of glucose, high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), insulin, and reduced glutathione (GSH) concentrations in red blood cells (RBC). Atherogenic index of plasma (AIP) and insulin resistance index (HOMA IR ) were calculated. The 8-week aerobic physical activity program resulted in significant decrease ( p  < 0.01) in serum glucose and LDL-cholesterol (LDL-C) levels, plasma TBARS concentrations ( p  < 0.05), and in significant decrease of HOMA IR ( p  < 0.01). TAS of plasma and GSH concentrations in RBC increased significantly ( p  < 0.01) over the study period. The results show that an 8-week aerobic training enhanced insulin sensitivity, and improved the balance between oxidants and antioxidants in healthy, postmenopausal women.}, author = {Karolkiewicz, Joanna and Michalak, Edyta and Pospieszna, Barbara and Deskur-\'{S}mielecka, Ewa and Nowak, Alicja and Pilaczy\'{n}ska-Szcze\'{s}niak, {\L}ucja}, citeulike-article-id = {4680384}, citeulike-linkout-0 = {http://dx.doi.org/10.1016/j.archger.2008.09.001}, citeulike-linkout-1 = {http://linkinghub.elsevier.com/retrieve/pii/S016749430800191X}, doi = {10.1016/j.archger.2008.09.001}, issn = {01674943}, journal = {Archives of Gerontology and Geriatrics}, keywords = {aerobics, exercise, oxidative\_stress}, month = {July}, number = {1}, pages = {e67--e71}, posted-at = {2009-05-29 17:29:40}, priority = {3}, title = {Response of oxidative stress markers and antioxidant parameters to an 8-week aerobic physical activity program in healthy, postmenopausal women}, url = {http://dx.doi.org/10.1016/j.archger.2008.09.001}, volume = {49}, year = {2009} }
