AbstractBack pain treatment in water has been commonly used although there is little evidence about its effects. One purported advantage for exercise is the reduced loading due to the buoyant force. The purpose of this study was to compare stature change, as a marker of spinal loading, after sitting in aquatic and dry land environments. Fourteen asymptomatic volunteers had their stature measured in a precision stadiometer, before and after a bout of physical activity and during a recovery period either sitting in water (head out of water immersion; HOWI) and sitting in a chair on land (SITT). Stature loss following exercise was as expected similar in both groups (SITT=89.2+/-5.4% and HOWI=86.5+/-8.1%; p=0.33). When stature recovery was compared between the water and land environments, HOWI (102.2+/-8.7%) showed greater recovery than SITT (86.5+/-6.3%) after 30 min (p<0.05). These results suggest that HOWI facilitated more rapid stature recovery through lower spinal loading and supports use of this technique to reduce spinal loading during recovery.
