Uphill or Down?

According to a study done by the Vorarlberg Institute for Vascular Investigation and Treatment (Austria), there's a difference in the effect of uphill vs downhill exercise.

Hiking on a mountainside gives the heart a health-promoting challenge, but the nature of the benefit depends on whether one is climbing or descending. A study conducted on an Alpine mountainside suggests that going up improves the body's processing certain fats, while going down enhances metabolism of a key sugar.
Both up and down hiking softened the spike of blood cholesterol that typically follows fat consumption, the team found. But only uphill exercise improved metabolism of fats called triglycerides, and only downhill exercise significantly increased glucose processing, Drexel says.
