Exercise Outdoors

Last weekend, I hiked with my cousin during our Girl's Weekend Getaway in Phoenix. Despite the desert heat, it was great to move our bodies, experience the mountains up close and chat with other hikers on the trail. Exercising outdoors has been shown to be significantly different than indoor workouts.

Science suggests there are benefits to exercising outdoors that can’t be replicated on a treadmill or a track. You stride differently when running outdoors, for one thing. Generally, people flex their ankles more when they run outside. They also, at least occasionally, run downhill, a movement that isn’t easily done on a treadmill and that stresses muscles differently than running on flat or uphill terrain. Outdoor exercise tends, too, to be more strenuous than the indoor version. In studies comparing the exertion of running on a treadmill and the exertion of running outside, treadmill runners expended less energy to cover the same distance as those striding across the ground outside, primarily because indoor exercisers face no wind resistance or changes in terrain, no matter how subtle.

In another study, volunteers were asked to go for two walks for the same time or distance — one inside, usually on a treadmill or around a track, the other outdoors. In virtually all of the studies, the volunteers reported enjoying the outside activity more and, on subsequent psychological tests, scored significantly higher on measures of vitality, enthusiasm, pleasure and self-esteem and lower on tension, depression and fatigue after they walked outside.

Another small study found that people have lower blood levels of cortisol, a hormone related to stress, after exerting themselves outside as compared with inside. There’s speculation, too, that exposure to direct sunlight, known to affect mood, plays a role.
