A study published in the American Journal of Sports Medicine finds that for most runners, it’s the intensity of their workouts that really determines how much of their endurance is preserved in the long term.
Running in the high-intensity range of running, for instance, has been shown to help preserve the healthiest and most explosive muscles.
However, the study also found that for some people, intensity and volume of their runs is a deciding factor.
This isn’t a new idea.
When running at a high intensity, runners are burning more energy than they are storing in their muscles, and that extra energy can be the difference between getting to the finish line or missing it altogether.
But this study, published in JAMA Internal Medicine, suggests that intensity is not the only determining factor in what types of runs are beneficial.
And it suggests that the amount of intensity you are running with is not a deciding feature.
Instead, you could also focus on how many repetitions you’re doing, how long you’re running, how many miles you’re walking, how much rest you’re getting, and how much oxygen you’re absorbing.
“It’s about what kind of intensity and frequency you’re using,” says Dr. David DeSimone, a professor of exercise science at the University of Florida and the lead author of the study.
He’s a former professor of physiology at the U.S. Naval Academy.
He and his team analyzed data from 1,200 participants between the ages of 18 and 64, and found that there was a correlation between how much intensity is used and how many sprints, full-kilometer runs, and treadmill sprints participants were completing.
So, if you’re training for a marathon, then you might be training for longer distances, DeSimones said.
“There is a clear correlation between running and cardiovascular endurance,” he added.
The researchers also looked at how much time people were running each week.
While participants ran between 7 and 9 hours a day, those who completed fewer than 50 sprints a week were less likely to be in a good state of health.
“Running may help us maintain a healthy state of fitness,” DeSimons said.
For instance, people who run a lot of short distance distances, like five to 10 miles, may need to do a lot more rest between runs.
And running a lot longer distances may need more rest, he said.
But what’s more important is how much recovery time is being used, which DeSimon said is more important than intensity.
“What we see in our study is that running is not about getting the maximum number of sprints in a short amount of time,” he said, “but it’s about the number of recovery times and recovery intervals.”
He explained that if you have to run a mile, that’s going to help you maintain a good health state, but if you run a long distance, that might not be the case.
“The amount of recovery time required to recover from a long run is not very great, and it doesn’t provide a lot in terms of muscle and cardiovascular recovery,” DeSomones said, adding that the longer you run, the more your heart will slow down.
And so, if running too much can make you feel sore, then running too little might also cause you to fatigue.
DeSimoni said that if a person runs too little during a run, they are more likely to get hurt.
“If you do a short run and a long jog, you’ll probably be able to sustain your body a little longer, but there’s probably a risk of injury,” he explained.
“We’re trying to make sure that people do as much as they can in a little bit of time.”
What is a marathon?
A marathon is defined as a marathon distance of at least 4,500 meters, a distance that can take you from New York City to the outskirts of Washington, D.C. It is one of the most physically demanding sports.
“When we do a marathon in New York, it is probably one of my favorite things to do,” De Simones said of running in a marathon.
“But it’s not something that everyone can do.
It’s not easy.
It doesn’t take much to get injured.
So it’s very different from what I do for a personal goal.”
In addition to running at high intensity on a treadmill, De Simone and his colleagues also measured how many steps a participant was taking on a typical marathon course, and the difference in distance ran.
They found that runners who took a lot less than the typical amount of steps were more likely than those who took less to get to the end of the course in a fair amount of distance.
“So, a very, very short distance runner is much more likely and a very long runner is less likely than a very short runner,” De Sims said.
What does it mean for marathoners?
While marathoners tend to be healthier than other runners because they’re not running for their
