Impact of Physical Exercise on Growth and Progression of Cancer in Rodents-A Systematic Review and Meta-Analysis.

The mode of exercise also did not yield a significant in-between subgroup significance as the result showed (Hedges' g = −0.89, 95% CI −1.37 to −0.40) for “Swimming,” (Hedges' g = −0.26, 95% CI −0.61 to −0.09) for “Treadmill running” and (Hedges' g = −0.16, 95% CI −0.65 to 0.33, Q-between = 5.44, df = 2, p = 0.07) for “Voluntary wheel running.” Through the fact that this difference was nearly significant, the type of exercise was able to explain 17% of the difference between the subgroups ( R 2 = 0.17).
