Here are the results of the study on sprint interval training or SIT. There was an 11% increase in max VO2 after the first cycle, reduced down to 6.4% after the second cycle, and finished at an 8% increase. Were the subjects fitter? Max VO2 notwithstanding, they absolutely were fitter. The reason we know that […]
Keeping with the theme of using interesting training techniques from the last Memos on HIIT training, this next study took it one step further. The objective was to see how fast subjects could get fitter using a sprint interval training program. I think I need to define some terms here. When we talk about getting […]
What were the results of HIIT training? The researchers found that there were reductions in overall weight as well as subcutaneous and visceral fat. What’s the difference? The fat just under the skin is subcutaneous fat; visceral fat is behind the abdominal muscles and around the internal organs and is more related to the development […]
One of the “facts” exercise professionals will tell you is that there is no such thing as spot reduction; by that I mean you cannot target a specific area of your body, let’s say your abdominal area, and lose fat by doing a targeted exercise such as sit-ups or leg lifts. You can make the […]
Researchers collected data from four prior studies that put a group of sedentary overweight and obese men and women on a walking program. To determine the distribution of muscle, fat, and bone, they took MRIs of their entire body. That gave the researchers not only the amount of muscle and fat mass, but exactly where […]
One of the questions that I’ve thought about over the years is what happens to the skeletal muscle and fat mass in non-exercising parts of the body. If you’re a runner or a walker, what happens to your upper body? What happens to your lower body? Do you retain or even increase the muscles in […]
I hope you all have a safe Memorial Day weekend. Here in the northern hemisphere, it’s the official kickoff of the summer season that ends with Labor Day. I alluded to a challenge, so let me lay it out for you: I want you to keep track of all the vegetables and fruit you eat […]
The title of this Memo is a concept that can be difficult to understand, especially when you read the studies I’m going to cover after the Memorial Day weekend. I’m going to talk about high intensity and even higher intensity exercise. What I don’t want to happen is for you to begin to read them, […]
A series of articles and studies published recently have called into question the use of statistics in examining large health databases. It’s especially pertinent to nutrition research because placebo-controlled trials are virtually impossible. See if this sounds familiar: eating meat is associated with an increased risk of colorectal cancer. The “association” is calculated by considering […]
I’ve said before that in my opinion, the single most important thing you can do to limit the problems of aging is to get to a normal body weight and maintain it. If you’ve been overweight most of your life, as I have been, that can be a real challenge. While the research on what’s […]
