Kurze Ausbrüche energiereicher Aktivität können schnelle molekulare Veränderungen im Blutkreislauf auslösen, das Wachstum von Darmkrebs stoppen und die Reparatur von DNA-Schäden beschleunigen, wie eine neue Studie gezeigt hat.

Short bouts of exercise can protect against bowel cancer, according to a study, giving researchers hopes for new cancer treatments.

Researchers from Newcastle University found exercising for just 10 minutes could halt bowel cancer growth and speed up DNA damage repair.

Dr Sam Orange, who led the study, said it showed exercise benefitted healthy tissues as well as potentially creating a more hostile environment for cancer cells to grow.

„In the future, these insights could lead to new therapies that imitate the beneficial effects of exercise on how cells repair damaged DNA and use fuel for energy,“ he said.

The research was conducted on 30 overweight or obese men who were healthy, with blood samples taken before and immediately after a 10-12 minute cycle ride.

Researches then exposed bowel cancer cells to pre- or post-exercise blood serum.

Acute exercise increased the concentration of 13 proteins, many of which are linked to reducing inflammation, improving blood vessel function and metabolism.
