A Role for Resistance Exercise in Cancer

That is a really interesting study. Take away from this one is to do resistance training which raises the heart rate to 120 for 7 minutes minimum. . That's the time required for almost all the blood volume to circulate through the exercising muscle. The exercising muscle (including the heart) undergoes physical changes which makes it likely that any circulating tumor cells would be burst by the pressures in the muscle.

Interesting that they found such an effect with healthy 20-30 yo males doing a bicep contraction with only a 10lb weight. Relative strength for this population would be significantly higher with a correspondingly lesser rate of stress in the contracted muscle. If a woman can lift 10lbs or more, or work up to 10lbs post-sx, I would assume the proportional relative force on the capillaries could be even greater than that of the test subjects.
