Prior to exploring running vs walking, it's important to note that the research is overwhelmingly clear that a sedentary lifestyle significantly increases numerous health risks and shortens lifespan.
Both running and walking offer quality of life benefits such as:
In terms of weight loss, the growing body of evidence indicates that running is best. Running burns more calories in less time.
A study comparing runners to walkers in The Journal of Obesity, found that runners experienced suppressed appetites while walkers’ appetites remained strong.
Running as high-intensity exercise elevates metabolic rate for a longer period of time after the exercise than walking – that means a longer period of calorie burning.
Running improves fitness more efficiently than walking and delivers more health benefit in terms of time invested. In other words, it takes more time walking than running to produce the same health benefits.
It takes 1 ½ to twice the distance to expend the same amount of energy walking as running. When comparing running vs walking briskly mile for mile, a study showed that both lowered risk for diabetes, high blood pressure and high cholesterol.
Approximately 200 calories can be burned by running six-miles per hour for ten minutes, or 300 calories during a brisk walk for one hour.
Walking is best for people who are obese or have problems with their ankles, back, knees, or injury.
Studies have found that running injury rates are significantly higher than walking injuries. Walking places less stress on joints and decreases the risk of injuries such as runner’s knee, and muscle strains.
More is better. Exertion is the key for increased levels of fitness, no matter what form of exercise you choose.
Although running expends 2.5 times more energy than walking, the effort during walking can be increased by increasing the pace, walking up hills, or wearing a weighted vest.
There is growing evidence that increasing time and/or intensity of any physical activity is better than steady-state exercise.
Alternating between running and walking is the very essence of interval training. Interval training is proving to greatly reduce abdominal fat, build strength, increase cardio endurance, and break through plateaus.
Mix it up, whether adjusting the settings on a treadmill, or walking up hills to increase demand on the glutes, calves and quads.
Maybe you don’t have to take a hard-line position on running
vs walking. The answer varies from person to person. Depending on your goals, fitness
level, health condition and personal preference, you can reap the benefits of
both by adding the variables mentioned above to increase heart rate for aerobic
fitness, time or distance for endurance, and intensity for strength.
When considering the possibility of injury, keep in mind that strength training is integral to overall fitness and may help to prevent running injuries.
The only wrong decision is to do nothing.
