How fast do you run? Speed truly kills . . .  fat

Parts of this article was taken from one of my earlier post.

Hiit weight training with sprints is the best way to shed unwanted weight and get fit in the shortest amount of time. For years I did steady state cardio exercises and realized many health benefits from doing them such as – improved respiration, weight loss, better balance and mental clarity.

However, the toll it took on my body, particularly my joints and feet, negated a lot of the health gains I made.

I have since switched to doing sprints as my cardio of choice and since doing this I have far surpassed the gains made doing steady state cardio. Because the time for doing sprints is shorter, I feel less stress on my joints and body overall and I have more muscularity. My runs are faster and my respiration is much better since I stepped it up to hiit workouts.

Hiit workouts doesn’t necessarily have to be running. If you have watch major sporting events like the  Olympics you will notice the body types and obvious fitness level of the swimmers and gymnasts who do sprints in the pool and gym as part of their training.

The same goes for cyclists and basketball players. Compare these body types to long distance runners or other endurance type athletes and the difference is clear to see.

I credit the Business Insider with the following article on why . . .

It might be healthier to run a mile than a marathon

 As it turns out, you can get some of the same benefits of long-distance running and other types of endurance training without ever passing the five-mile mark.

That’s right. Running fast and hard for just five to 10 minutes a day can add years to your life, just as running for hours can. In fact, people who run for less than an hour a week — so long as they get in their few minutes of daily running — get similar benefits in terms of heart health compared with people who run more than three hours a week.

That finding squares with recent research showing that short bursts of intense exercise can provide some of the same health benefits as long, endurance-style workouts.

Marathoners, Meet Interval Training

One of the most popular forms of the quick workout — and the one that has been studied the most — is interval training. Basically, you work yourself as hard and fast as you can for a few minutes, rest, then do it again. The best part? It typically lasts only between five and 10 minutes total.

Despite consuming far less time than a marathon training session, an interval workout may actually be healthier in the long run (pun intended), according to some research done in the past decade.

A 2012 study comparing a group of runners who did traditional, continuous runs with a group of runners who did interval training found that both groups achieved nearly the same results. There was one small difference, though. The interval trainers had better peak oxygen uptake, an important measure of endurance.

And a recent study in the journal Diabetologia found that doing walking interval training — an hour of alternating between three minutes of brisk walking and three minutes of stopping — helped people with diabetes control their blood-sugar levels far better than simply walking at the same pace continuously.

Still Not Convinced?

Consider this: Distance running could actually be bad for you.

There’s some evidence to suggest that prolonged, intense exercise — such as the type necessary in the weeks and months before a marathon and in the race itself — can have some unhealthy side effects, from reduced immune function to digestive issues.

Working the body to its maximum, some research shows, can reduce the body’s natural ability to fend off upper-respiratory infections including colds and the flu. Short bouts of activity, on the other hand, improve immune function. Quick workouts appear to not only reduce your chances of getting sick, but to reduce the severity of an illness when you do come down with something.

Up to 71% of long-distance runners also experience abdominal cramping and diarrhea (the latter being so frequent that runners have a term for it: “Runner’s Trots,” aka “runner’s diarrhea“). Many runners (even those without a history of it), experience acid reflux, a condition with effects like heartburn, indigestion, coughing, hoarseness, and asthma during and immediately after a long run.

Here’s what it all comes down to: Whether you stick to a long-distance routine or opt for a quicker, daily exercise plan, it’s important to keep in mind that more is not always better.
