To assess power, they used 8-second all-out sprints on a stationary bike and calculated the resulting force-velocity curve. But strength isn’t the same as power, which also depends on how quickly you can produce force. Simple tests of quadriceps and hamstring strength showed no differences between the groups. Bounding up steep hills, after all, requires powerful bursts of force. One longstanding question for both athletes and researchers is whether trail runners need to be more powerful. But the results still offer some interesting insights about the similarities and differences between top road and trail runners. That meant using a treadmill that only went up to around 7:00 miles and 10 percent incline-modest challenges for athletes of that caliber. Actually, that’s not quite right-the researchers brought the lab to national-team training camps hosted by the French Athletics Federation for their trail and road-running teams. Drop Kilian Jornet into a road race or Emily Sisson into a trail race, and they’d be suddenly mortal.Ī new study from French researchers at the University of Lyon, published in the Journal of Strength and Conditioning Research, probes this question by bringing elite road and trail runners into the lab for testing. The other is that they’re two separate sports whose demands favor different characteristics. One is that running is running: terrain and environment are minor details, and the best athletes in one discipline will probably also succeed in the other one. There are two schools of thought about the differences between trail running and road running. ![]() Heading out the door?
