Exercise May Boost The Immune System



A new research suggests that exercise could improve your immune system and possibly even help it protect against cancer.

Regular exercise is an excellent way to enhance your mood and get in shape. Scientists may soon be able to add yet another item to the list of exercise’s well-documented health benefits.

A new study conducted by researchers at the University of Nebraska Medical Center and the Rocky Mountain Cancer Rehabilitation Institute, suggests that when cancer survivors exercise for several weeks after they finish chemotherapy, their immune systems remodel themselves to become more effective, possibly prevent future incidences of cancer.

The finding may help describe why exercise can significantly decrease the chances of secondary cancers in survivors or reduce the possibilities of cancer altogether in individuals who have never had the disease.

“What we’re suggesting is that with exercise, you might be getting rid of T cells that aren’t helpful and making room for T cells that might be helpful,” study investigator Laura Bilek, of the University of Nebraska Medical Center, reported in a statement.

“If exercise indeed strengthens the immune system and potentially improves cancer surveillance, it’s one more thing we should educate patients about as a reason they should schedule regular activity throughout their day and make it a priority in their lives,” she added.

The researchers first took blood samples from each of 16 volunteers, who had survived cancer, all but one of whom had just completed their chemotherapy treatments, to examine how many senescent and naive T cells each had.

Then, the study participants are asked to complete a 12-week exercise plan that includes cardio workouts, weight training and flexibility.

At the end of the study the researchers have checked again the activation of T lymphocytes.

In the study’s findings, the authors noted that that the ratio of senescent to naive T cells changed favorably in the majority of participants, with most of the study subjects regaining greater numbers of the naive variety.

The new research was presented at the Integrative Biology of Exercise VI meeting.
