Is Light Exercise Better For Overall Health vs High Intensity Exercise?

Описание: We're going to review two studies. The first was published in PLOS One titled: "Minimal Intensity Physical Activity Improves Insulin Action and Plasma Lipids More than Shorter Periods of Moderate to Vigorous Exercise in Sedentary Adults".

What else needs to be said; the title says it all! Just kidding. The study looked at the difference of utilizing 1 hour of high intensity exercise versus substituting 4 to 5 hours of walking (not brisk walking, basically just moving) or standing.

Both groups were made to burn the same amount of calories.
Interestingly, the walking/standing group showed improved insulin sensitivity (meaning a beneficial change to metabolism), decreased triglycerides (showing fat burning) and increased HDL (good cholesterol) versus no such changes in the high intensity group.

The study authors concluded that 1 hour of daily physical exercise can't compensate for the negative effects of inactivity on insulin sensitivity and plasma lipids (cholesterol) if the rest of the day is spent sitting.

Moving a good part of your day is the best for metabolic health, improving all cause mortality and achieving fat loss benefits.

Another study published in the Journal of Environmental Research and Public Health looked at high intensity interval training (HIIT) in both active and inactive individuals.

Both active and inactive individuals saw a benefit from occasional high intensity interval training as regards their metabolic health.

Specifically "occasional surges above baseline" which is obviously quite different depending if you're normally active or sedentary, is important for overall metabolic health and fat loss.

Do these studies contradict each other? I don't believe so. It's important to get a lot of movement each day AND sprinkle in some higher intensity training a few times per week.

Let me know if some of my suggestions are helpful at the end of the video.
