Maximizing caloric expenditure and minimizing patellofemoral joint loading during running

Findings from the present study suggest that moderately graded running can increase caloric expenditure without increasing cumulative patellofemoral joint loading compared to slow level ground running. Given that burning calories is the primary goal for many recreational runners, this suggests that a combination of uphill and downhill running may be an effective training approach to increase caloric expenditure without increasing injury risk.
