I love taking long walks in the park near my house. Walking is peaceful to me, and I love the chance to be outside and get my legs moving. And while I also enjoy running and would love to run more, it is definitely more of a challenge for me; it takes a lot of work and training to make running enjoyable. We all know that exercise is good for us; exercise benefits digestive health, osteoporosis, depression, fatigue, and more. While any exercise is definitely better than none, there are advantages to certain forms of physical activity. Research shows that there is a difference between walking vs. running. Running allows you to lose more weight, protects against mortality, and helps you to stay energy efficient as you age, too.
Walking vs. Running: Which is Better?
Previously, researchers thought that all forms of exercise were equal as long as the total energy output at the end of the workout was the same. This means that walking, which is less intense, could offer the same benefits as high-intensity running if you walked for long enough. And while this notion might hold some truth, it isn’t the whole story; certain forms of exercise do offer advantages over others.
A study from 2013 followed men and women who either ran or walked regularly over six years. They found that runners had greater reductions in body mass index (BMI) than walkers over the trial period. The results showed that runners were protected against age-related weight gain while walkers were not.
Another study in women diagnosed with breast cancer found that those who ran post-diagnosis were more likely to survive than post-diagnosis walkers. Women who were the most active runners were 95% more likely to survive than the least active runners. The study also found that the runners maintained better weight control.
The Importance of Staying Active as You Age
As we age, our walking tends to deteriorate. And this is not a good thing; impaired walking performance is a predictor of morbidity in older adults. One of the reasons for impaired walking performance is the increase in metabolic cost for walking that occurs as we age. Older people spend more energy on walking than young adults do, but luckily there is a way to prevent this kind of age-related change.
Running Keeps Us Energy Efficient
A recent study looked at the energy efficiency of walkers vs. runners, all older than 65 years old. They studied the amount of energy it took for both regular walkers and regular runners to walk at different speeds. They found that older runners used 7% to 10% less metabolic energy to walk compared to older walkers. The runners only had to increase their power output by 86% when walking at the highest speed, while walkers had to increase their output by 95%. These results showed that runners spend less of an energetic cost to walk than regular walkers do.
Although the authors don’t exactly know why this happens, there are many factors that come into play, such as better muscle efficiency and stronger muscles in runners. Another study suggests that runners have more effective walking mechanics in the ankle joint than walkers, which they might be able to use for more efficient walking.
If your health allows it, running regularly might have some profound impacts on your health. But keep in mind that this research does not discourage walking—walking can be extremely powerful as well in keeping your health in top shape. In fact, one study found that walking might be better than running for lowering cholesterol. Just make sure that you are moving as much as you can, as often as you can.
If you are not a regular runner, the key is to start small. Try adding short bouts of running to your regular walk. Warm up by walking, and then start running for only a few minutes at a time, taking long walk breaks in between your bouts of running. Slowly but surely, you will be able to shorten your walking time and increase your running time, so that you only take short (if any) walking breaks. Another strategy is to start by running only about 5-10 seconds out of each minute of your walk, and slowly build that up over time.
Setting yourself a long-term goal, such as training for a local 5K race, might help you to get motivated. For other ideas on how to get motivated to exercise, read more here.
