Guest guest Posted March 13, 2007 Report Share Posted March 13, 2007 Somewhere in all of those links about shoveling snow should have been the references that it's not the aerobic aspect of the activity that creates the problem but the anerobic aspect. Blood pressure rates as high as 400 systolic have been measured. If your heart is not used to that back pressure, then you will quite possibly encounter cardiac difficulties, regardless of food intake. Eskimos have a greater incidence of death by stroke than CVD. A maximal cardiac stress test will not approach that level of pressure, and is primarily geared towards aerobic output.

Blood pressure rates as high as 400 systolic have been measured. If one doesn't hold his breath while lifting the shovel - a Valsalva maneuver - , I doubt if such high systolic pressures will be approached; iow, continue to breath through the acute phases of the exercise, as weight trainers instruct for the similar case of lifting (heavy) weights. Also, if one can shovel snow for an extended period without being forced to stop, as in anarobic exercise, the exercise is in fact aerobic.
