ABSTRACT
The present study was conducted to investigate the effect of corn silk,
pumpkin seeds and creatine supplementation on oxidative stress biomarker
as well as liver function and glycogen content of adult male exercised rats.
Fifty male albino rats were fed on basal diet for one week for adaptation.
During the adaptive week all rats (except negative control group) were
exposed to day after day forced treadmill running exercise for 10 min. Rats
were divided into two main groups, the first main group (n=10 rats) was fed
on basal diet only and served as negative control group. The second main
group (exercised rats) were divided into 4 subgroups (10 rats each) as
followed:-Subgroup 1: were fed on basal diet and had run for 10, 15, 20 and
25minutes (15 days for each time period), respectively and served as
positive control group. The Subgroups (2-4) as the same of positive control
subgroup and were fed on basal diet supplemented with 4% corn silk
powder, 4% pumpkin seeds powder and 4% creatine powder, respectively.
At the end of the experimental period (60 day), 5 rats of each subgroup were
exposed to the exhausting treadmill test and the run time was recorded, then
all experimental rats were scarified. Findings of these study prove that corn
silk and pumpkin seeds were a good source of flavonoid which help to
scavenge the oxidative stress substances, and improve liver functions , while
creatine recorded the largest glycogen quantity in gastrocnemius muscles
among supplemented groups, but it causing an elevation ammonia, and AST
levels on the group which exposure to exhaustive time test. It could be
recommended that corn silk and pumpkin seeds have the ability to eliminate
physical fatigue and prolong the training period without fatigue
