According to the latest research, strength training is one of your best defenses against oxidative stress.

In fact, after a mere 6 weeks of of workouts, test subjects saw significant improvement in two key markers of oxidative stress

And when you consider that oxidative stress is directly responsible for atherosclerosisParkinson’s diseaseheart failuremyocardial infarctionAlzheimer’s diseasefragile X syndrome, chronic fatigue syndrome and aging in general, perhaps we should stop selling gym memberships based on getting a wicked six-pack and focus more on….living healthier, living longer, living better, etc…

The Research

J Strength Cond Res 24(9): 2491-2497, 2010

The purposes of this study were:

  1. to determine whether acute resistance exercise training (RET) induces oxidative stress,
  2. to determine whether chronic RET decreases oxidative stress level at rest condition in previously untrained men,
  3. and also to investigate how the RET intensity influences the training-induced oxidative stress response.

Sixteen young men who did not have RET experience in the past were randomly divided in 2 groups.

The hypertrophy-intensity group performed 3 sets of 12 repetitions at an intensity corresponding to 70% of 1 repetition maximum (1RM), whereas the strength-intensity group performed 3 sets of 6 repetitions at an intensity corresponding to 85% of 1RM.

The workouts  involved 6 exercises, and it was performed 3 times a week on nonconsecutive days for 6 weeks.

Blood samples were obtained just before (pre-RET) and immediately after RET (post-RET) on the first day of the first week, on the last day of the fourth and sixth weeks.

After 6 weeks of training, pre-RET values of malondialdehyde (MDA) significantly decreased and pre-RET values of glutathione (GSH)significantly increased in both hypertrophy- and strength-intensity groups.

These alterations occurred independently of training intensity.

Conclusion

This study indicated that hypertrophy- and strength-intensity whole-body RET performed regularly for 6 weeks, decreased MDA concentration and increased GSH level in healthy young men.

Results suggest that chronic RET has protective effects against oxidative stress similar to aerobic exercises and that these effects seem to be independent of the training intensity.
