A Study of effect of Aerobic Strenuous Exercise on Oxidative Stress in Young Healthy Individuals by using Serum Malonyldialdehyde Levels

Intense physical activity in the form of strenuous exercise causes more oxygen consumption and more free radical production termed as oxidative stress, which is in the form of increased by products of lipid peroxidation (increased MDA levels) as the intensity and duration of exercise was more. On the other hand in other study it was found that endurance training reduced MDA level which is a byproduct of lipid peroxidation. The present study is designed to see the effect of "Aerobic strenuous exercise" on oxidative stress in young healthy individuals over a period of six months.

The present study was undertaken 32 male individuals practicing aerobic strenuous exercise. Aerobic moderate to severe type of exercise given on bicycle ergometer. Pulse rate was used as an indicator of severity of exercise. Serum Malonyldialdehyde (MDA) was estimated as an index of lipid peroxidation.

There is statistically significant increase in average serum MDA values between the before & after 3 months of Aerobic strenuous exercise training. (p<0.05). Also there is statistically highly significant (p<0.001) decrease in average serum MDA values between before and after the 6 months of aerobic strenuous exercise training.

Awareness about the effects of short term exercise and long term endurance exercise should be spread amongst all the individuals joining these types of exercise schedules at various centers. They should be encouraged for long endurance exercises for most beneficial effects on the body.
