Objective:
The present study was aimed to assess the effect of Resveratrol supplementation, endurance exercise and acute exercise training on oxidative stress and tissue damage markers.
Methods:
Sixty-four male Wistar rats were categorized into four groups including resveratrol group, exercise group, exercise + resveratrol group (n= 16) and control group (n= 16). RES was orally administered to male rats for 28 day at a dose of 10 mg per kg body during exercise. Following the familiarization sessions, rats were acclimated to a calibrated motor driven rodent treadmill for endurance exercise and acute exercise implementation. Changes in oxidative stress and tissue damage markers including 8-hydroxy-2'-deoxyguanosine (8-OhdG), Lactate dehydrogenase (LDH), Creatine Phosphokinase (CPK), protein carbonyl were biochemically measured using commercial ELISA kits based on the manufacturer's instructions.
Results:
The endurance and acute exercise training led to an increase in the levels of CPK and LDH, However, following the endurance and acute exercise training, a reduction in the level of carbonyl and 8-OHdG was observed. RES supplementation did not have any effect on the levels of CPK and LDH; nevertheless, reduced significantly carbonyl, and 8-OHdG levels. Based on this evidence, RES may have protective effects against exercise-induced oxidative stress.
Conclusion:
This study provides further evidence of the antioxidant effects of RES after exercise. However, several factors such as type and duration of exercise, the type of model, the amount of RES supplementation and the time-course consideration can affect the quality of the results. For this reason, further studies in this field are required.

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
01:27Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
