To better understand these effects, we investigated the relationship between loading directions during slow running and the rapid changes in T2 times occurring in the lumbar IVDs before and after running.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    Sixteen healthy male students were fitted with a triaxial accelerator and ran on a treadmill at 8\u2009km\/h for 1\u2009minute.
