Abstract
The purpose
of this study was to compare changes of antioxidant status after two
different resistance exercise loading patterns (pyramid and inverse
pyramid). Alteration in biological activity of superoxide dismutase
(SOD), radical scavenging activity on 2, 2-diphenyl-2-picrylhydrazyl
hydrate (DPPH) and concentration of uric acid (UA) in human saliva was
investigated. In practice, 25 experienced trained male participated in
the study. During 2 test days, subjects performed resistance exercise
protocols with pyramid and reverse pyramid loading patterns. Their
un-stimulated saliva samples were obtained pre exercise and 5 minute
post exercise. The results showed that after exercise, SOD activity was
significantly higher in both PLP and RPLP when compared to their values
at rest. However, the SOD values for the RPLP were significantly higher
than for the PLP (p<0.05). Uric acid values increased significantly
in the two resistance exercise systems (PLP, RPLP) when comparing to
the resting values (p<0.05). In addition, there was no significant
difference between corresponding UA values of the two systems (p>
0.05). In the case of radical scavenging activity (%DPPH), both PLP and
RPLP showed significant increases 5 minutes after exercise sessions
compared to pre-exercise (p<0.05). In conclusion, inverse pyramid
loading pattern proposed in the current study promoted higher oxidative
stress biomarker (DPPH, SOD and UA) and antioxidant modulations
compared with resistance traditional interval training.
