The purpose of this present study was to investigate the effect of VitaminQ supplementation on antioxidant enzyme activities and cardiorespiratory function following prolonged exercise in trained triathlers. Male 14 healthy college students of trained triathlers participated in exercise sessions. The subjects were divided into 2 groups, as Non-supplement(NS) or VitaminQ supplement(VQ) groups. VitaminQ subjects were participated in two exercise sessions: an initial prolonged exercise(swim 750m, running 10㎞) and 70%V O2max treadmill running exercise.
The Non-supplement group fed normal diet. VitaminQ group adminstated 90㎎/day for 4weeks. Venous blood samples were drown from the forearm antecubital vein pre-supplement, pre-exercise and immediately post-exercise. The results of this study can be summarized as follow:
First, the SOD activity of RBC was not changed, while the GPx, GR
or GR/GPx activies of Hb were significantly increased following prolonged
exercise with CoQ10 supplementation.
Second, 70%VO2max treadmill
running exercise increased significantly the V O2max and VE, but the
heart rate significantly decreased.
In conclusion, the present results clearly show that the VitaminQ supplementation gave rise to increase the GPx or GR activies and to improve the cardiorespiratory function.
