Megjegyzések:Background : Growing evidence shed light on the significant effects of physical activity on immunomodulation. Consequences may largely depend on the type of activity, its intensity and duration. However, little information is available regarding the immunological effects of sporting activities in older ages. The aim of our study was to examine the changes in a wide spectrum of lymphocyte subtypes after a period of regular workout among healthy women of different ages. Method : In a cross- sectional study, we enrolled 34 young adult women (between ages of 19- 23 years), 8 of them were a player of a team in Hungarian Women ' s Volleyball League, while 26 of them were not engaged in regular physical activity. Additionally, we enrolled 16 elderly women (between ages of 60- 75 years) not engaged in regular physical activity. During a follow- up study, 17 from the group of non- athlete young adults completed a 12- week Pilates workout program, while the group of elderly women took part in a 6- week lightweight conditioning gymnastic exercise program once a week. The percentages of peripheral natural killer (NK), NKT cells, T and B lymphocyte subtypes (early- /late- activated T, naive and memory T, cytotoxic T (Tc), T- helper (Th)1, Th2, Th17, T regulatory type 1 (Tr1), CD4 + CD127- CD25 bright Treg, as well as naive and memory B cells) were determined by flow cytometry based on the staining of extracellular markers and intracellular cytokines. Results : The investigated baseline parameters did not show significant differences between athlete and non- athlete young adults. In the elderly, levels of CD3 + 6B11 + NKT cells were lower, while ratios of CD4 + Th/CD8 + Tc cells were higher compared to the values of younger individuals. At the end of exercise programs, changes observed among 60- 75 year- olds were more pronounced compared to alterations developed in younger subjects. In elderly women, percentages of IgD+ naive B cells decreased, while levels of CD27 + switched- memory B cells increased. Furthermore, proportions of CD4 + IL- 4 + Th2 cells increased, while levels of CD8 + IFNgamma+ Tc cells and immunosuppressive CD4 + CD127- CD25 bright Treg cells decreased as the result of regular exercise. Conclusion : Differences observed after lightweight exercise programs reflect a presumably enhanced immunoreactivity and increased ability for immune responses, especially in older ages.
