Conclusions Leisure time physical activity may reduce the risk of chronic LBP by 11%–16 % .
Background There are plausible mechanisms whereby leisure time physical activity may protect against  low back pain ( LBP )  but there have been no quality systematic review s and meta-analyses of the subject .
Objective This review aims to assess the effect of leisure time physical activity on non-specific LBP .
The Predictive Relationship of Physical Activity on the Incidence of Low Back Pain in an Occupational Cohort
Objective : Quantify the relationship between physical activity and development of  incident low back pain ( LBP ) .  Methods : This nested prospect i ve cohort study utilized an objective measure of physical activity in 68 participants with 30 incident cases of LBP .  Physical activity was divided into tertiles and quartiles . Univariate and multivariate relative risks and hazard ratios were calculated . Results : Comparing highest to middle tertile of light activity demonstrated a statistically significant relative risk of 3.68 for developing incident LBP . Lowest and highest tertile of minutes of moderate/vigorous activity yielded statistically significant relative risks of 4.60 and 6.14 , respectively . Multivariate analyses demonstrated similar associations . Conclusions : Moderate amounts of physical activity were protective for the development of LBP  in this cohort , after adjustment for risk factors . This nonlinear relationship suggests higher levels of activity do not confer increased LBP prevention
