Abstract
Osteoarthritis of the knee (kOA) is a disease that mainly affects the elderly and can
lead to major physical and functional limitations. However, the specific effects of
walking, particularly on the immune system, are unknown. Therefore, this study aimed
to analyze the effect of 12 weeks of walking (3×/week) on the leukocyte profile and
quality of life (QL) of elderly women with kOA. Sixteen women (age: 67±4 years, body
mass index: 28.07±4.16 kg/m2) participated in a walking program. The
variables were assessed before and after 12 weeks of training with a progressively
longer duration (30–55 min) and higher intensity (72–82% of HRmax determined using a
graded incremental treadmill test). The QL was assessed using the Medical Outcomes
Study 36-Item Short Form Health Survey (SF-36), and blood samples were collected for
analysis with a cell counter and the San Fac flow cytometer. Walking training
resulted in a 47% enhancement of the self-reported QL (P<0.05) and a 21% increase
in the VO2max (P<0.0001) in elderly women with kOA. Furthermore, there
was a reduction in CD4+ cells (pre=46.59±7%, post=44.58±9%, P=0.0189) and a higher
fluorescence intensity for CD18+CD4+ (pre=45.30±10, post=64.27±33, P=0.0256) and
CD18+CD8+ (pre=64.2±27, post=85.02±35, P=0.0130). In
conclusion, the walking program stimulated leukocyte production, which may be related
to the immunomodulatory effect of exercise. Walking also led to improvements in the
QL and physical performance in elderly women with kOA.

Muscle strength, muscle balance, physical function and plasma interleukin-6 (IL-6) levels in elderly women with knee osteoarthritis (OA). Arch Gerontol Geriatr 2011; 52:322-6.

Abstract
An increased circulating level of inflammatory cytokines has been associated with sarcopenia, functional disability, chronic diseases, and mortality in the elderly. Osteoarthritis (OA) is a disease common to this population, the seriousness of articular degeneration has been associated to the increase in some cytokines, IL-6 among them. The aim of the present study was to correlate IL-6 plasma levels with muscle strength, endurance, muscle balance hamstring/quadriceps (H/Q) and physical function in 80 elderly women (71.2 ± 5.3) with knee OA. IL-6 was measured using enzyme-linked immunosorbent assay (ELISA). Quadriceps and hamstring muscle strength, endurance and hamstring-quadriceps muscle balance were assessed using a Biodex system 3 pro(®) isokinetic dynamometer. Physical function was assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Spearman's correlation coefficient was used to explore the relationship between the outcomes at the significance level of α=0.05. IL-6 was inversely correlated to the endurance of the hamstring muscles (r=-0.232; p=0.03) and muscle balance (H/Q) on the lower right side at 180°/s (r=-0.254; p=0.023). No significant correlation between IL-6, muscle strength and physical function was found. Our results show that elevated levels of IL-6 may possibly contribute to the reduction of the endurance of hamstring muscles and H/Q muscle balance in the elderly studied.
