Effect of Resistance Training on Hematological Blood Markers in Older Men and Women: A Pilot Study

The aim of this study was to examine the effects of resistance training on hematological blood markers in older individuals. Twenty-nine men and women participated to this study. Subjects were randomized in 2 groups: (1) control (n = 13) and (2) resistance training (n = 16). At baseline and after the intervention, subjects were submitted to a blood sample to determine their hematological profile (red blood cells, hemoglobin, hematocrit, platelets, leukocytes, neutrophils, lymphocytes, monocytes, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, red cell distribution width). At baseline, no difference was observed between groups. Moreover, we found no significant difference after the intervention on any of these markers. A 6-month resistance program in healthy older individuals seems to have no beneficial nor deleterious effects on hematological blood parameters. However, resistance training was well tolerated and should be recommended for other health purposes. Further studies are needed to confirm these results in a large population.

Effects of resistance training combined with antioxidant supplementation on fat-free mass and insulin sensitivity in healthy elderly subjects

The aim of this study was to verify the effect of resistance training and antioxidant supplementation on fat-free mass (FFM) and insulin sensitivity (IS). The results demonstrate that 6 months of resistance training combined with antioxidant supplementation significantly increased FFM without concomitant significant improvement in IS in older adults.

Fat mass threshold associated with a significant deterioration of insulin sensitivity in postmenopausal women.

The aim of this study was to establish a cut-off value of percentage of fat mass (%FM) at which insulin sensitivity (IS) is significantly altered in sedentary postmenopausal women. Our results suggest that maintaining a %FM below 41% would minimize the deterioration of IS and its associated risks.
