Increase in
heart metabolism during severe
exercise facilitates
production of ROS and result in
oxidative stress. Due to shortage of information, the effect of chronic strength
exercise on
oxidative stress and contractile function of the
heart was assessed to explore the threshold for
oxidative stress in this kind of
exercise training.
Male Wistar rats (80) were divided into two test groups exercised 1 and 3 months and two
control groups without
exercise. Strength
exercise was carried by wearing a Canvas Jacket with
weights and forced
rats to lift the
weights.
Rats were exercised at 70% of maximum lifted weight 6 days/week, four times/day, and 12 repetitions each
time. Finally, the
hearts of ten
rats/group were homogenized and (..) (AU)
