Is Running on a Treadmill Harder or Easier Than Running Outside? 
New research debunks some persistent ’mill myths.

 - A new meta-analysis published in Sports Medicine analyzes 34 studies that compare the physiological, perceptual, and performance differences between running outside and running on a treadmill.
- The research concludes that when runners speed up on a treadmill, they have higher heart rates and report feeling more fatigued than when they run the same speed on land.
- Runners display more endurance running outside than on a treadmill.

In a new research published in Sports Medicine, scientists from Australia sought to answer these questions by investigating the differences in running performance on a treadmill versus real ground. To gather this data, they analyzed 34 studies that compared treadmill runs to “overground” (outdoor) runs. Twelve of the studies asked participants run on a 1 percent grade on the treadmill, while the others used higher or lower inclines.

The researchers were focused on three key measures of comparison: physiological (how hard the runners’ bodies were working to maintain pace and finish their workouts, measured by heart rate, blood lactate levels, and VO2 max), perceptual (how hard the workout felt for the runners), and performance (how the runners performed in time trials).
