Perhaps you should try some spelling variations:
exertion processing » execution processing (Expand search), extrusion processing (Expand search), emotion processing (Expand search)
decreases exertion » decreases exercise (Expand search), decreases expression (Expand search), decreases permeation (Expand search)
action decreases » fraction decreases (Expand search), infection decreases (Expand search), reduction decreases (Expand search)
decrease action » decrease asian (Expand search), decrease adhesion (Expand search), decreases lactic (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease action decreases exertion processing ) OR ( decrease OR decrease of decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease action decreases exertion processing ) OR ( decrease OR decrease of decrease ))*.
