Tai Chi Shows More Effects than Walking on Oxidative Stress in Older Adults
August 16, 2013 -
It has recently been reported that the
practice of Tai Chi reduces oxidative stress (OxS), but it is not clear whether
walking or Tai Chi produces a greater antioxidant effect. A new study by the
National Autonomous University of Mexico aimed at evaluating the effect of the
practice of Tai Chi and walking on markers for OxS.
The researchers carried out a quasi-experimental study with
106 older adults between 60 and 74 years of age who were clinically healthy and
divided into the following groups: (i) control group (n = 23), (ii) walking
group (n = 43), and (iii) Tai Chi group (n = 31).
The researchers measured the levels of lipoperoxides (LPO),
antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx),
and total antioxidant status (TAS) pre- and post-intervention in all subjects.
They found lower levels of LPO in the Tai Chi group compared with the walking
group. Likewise, they observed significantly higher SOD activity and lower
OxS-score in the Tai Chi group.
The findings suggest that the practice of Tai Chi produces a
more effective antioxidant effect than walking.
