Walking and Running. Do You Get the Same Workout?
There are many reasons why people start running: Busting stress, boosting energy, or snagging that treadmill next to a longtime gym crush are just a few. What’s more, running can keep your heart healthy, improve your mood, stave off sickness, and aid in weight loss. But depending on your personal goals, going full speed isn’t the only route to good health.
While walking can provide many of the same health benefits associated with running, a growing body of research suggests running may be best for weight loss. Perhaps unsurprisingly, people expend 2.5 times more energy running than walking, whether that’s on the track or treadmill. For a 160-pound person, running 8 mph would burn over 800 calories per hour compared to about 300 calories walking at 3.5 mph.
And when equal amounts of energy were expended, one study found runners still lost more weight. In this study, not only did the runners begin with lower weights than the walkers—they also had a better chance of maintaining their BMI and waist circumference.
Running may also regulate appetite hormones better than walking. In another study, after running or walking, participants were invited to a buffet, where walkers consumed about 50 calories more than they had burned and runners ate almost 200 calories fewer than they’d burned. Researchers think this may have to do with runners’ increased levels of the hormone peptide YY, which may suppress appetite.
However, aside from weight loss, walking has definite pros. Researchers looked at data from the National Runners’ Health Study and the National Walkers’ Health Study and found that people who expended the same amount of calories saw many of the same health benefits. Regardless of whether they were walking or running, individuals saw a reduced risk of hypertension, high cholesterol, diabetes, and improved better cardiovascular health. And running does have downsides: It puts more stress on the body and increases the risk for injuries like runner’s knee, hamstring strains, and shin splits.
When running isn’t in the cards, walking with added weight might be the next best bet for an effective workout. Research shows that walking on the treadmill while wearing a weighted vest can increase the metabolic costs and relative exercise intensity. Similarly, increasing the incline on the treadmill makes for a more effective walking workout. A study showed that walking at a slow speed (1.7 mph) on a treadmill at a six-degree incline can be an effective weight management strategy for obese individuals, and help reduce risk of injury to lower extremity joints. Picking up the pace slightly almost always helps. One study found speed walkers had a decreased risk of mortality over their slower counterparts.
Regular cardio (at any speed) is part of a healthy lifestyle. But, lap for lap, running burns about 2.5 times more calories than walking. Running may also help control appetite, so runners may lose more weight than walkers no matter how far the walkers go. Overall, the best possible workout for anyone would be a nice run, whether outside during nice weather, or inside at the gym while watching a favored television show.
