MikeNelson2 NelsonInterval training versus Endurance has long been an issue.
Instead of mixing both, this article emphasizes Interval. -

Reno DomenicoThe potency of interval training is nothing new. Many athletes have been straining through interval sessions once or twice a week along with their regular workout for years. But what researchers have been looking at recently is whether humans, like that second group of rats, can increase endurance with only a few minutes of strenuous exercise, instead of hours? Could it be that most of us are spending more time than we need to trying to get fit?

After two weeks, both groups showed almost identical increases in their endurance (as measured in a stationary bicycle time trial), even though the one group had exercised for six to nine minutes per week, and the other about five hours. Additionally, molecular changes that signal increased fitness were evident equally in both groups. “The number and size of the mitochondria within the muscles” of the students had increased significantly, Gibala says, a change that, before this work, had been associated almost exclusively with prolonged endurance training. Since mitochondria enable muscle cells to use oxygen to create energy, “changes in the volume of the mitochondria can have a big impact on endurance performance.” In other words, six minutes or so a week of hard exercise (plus the time spent warming up, cooling down, and resting between the bouts of intense work) had proven to be as good as multiple hours of working out for achieving fitness. The short, intense workouts aided in weight loss, too, although Gibala hadn’t been studying that effect. “The rate of energy expenditure remains higher longer into recovery” after brief, high-intensity exercise than after longer, easier workouts, Gibala says. Other researchers have found that similar, intense, brief sessions of exercise improve cardiac health, even among people with heart disease.
There’s a catch, though. Those six minutes, if they’re to be effective, must hurt.
