Damn…I hate interval training but these data are very compelling on the advantage of interval training in improving mitochondria function. Time to reconsider my resistance exercise only program.
…”But more unexpected results were found in the biopsied muscle cells. Among the younger subjects who went through interval training, the activity levels had changed in 274 genes, compared with 170 genes for those who exercised more moderately and 74 for the weight lifters. Among the older cohort, almost 400 genes were working differently now, compared with 33 for the weight lifters and only 19 for the moderate exercisers.
Many of these affected genes, especially in the cells of the interval trainers, are believed to influence the ability of mitochondria to produce energy for muscle cells; the subjects who did the interval workouts showed increases in the number and health of their mitochondria — an impact that was particularly pronounced among the older cyclists”
Here is a simple HIIT session in a 39 second video:
I have heard of so many mistakes being made by people taking testosterone replacement therapy. Some mistakes seriously impacted their quality of life, or...
I know I sound like I'm a broken record, because it made a difference for me. I mean, when I had low testosterone, back in the horrible days, I couldn't even process information. I couldn't talk to my doctor. I couldn't advocate for myself. I was like a doormat. Eventually, obviously, people see the difference, and sometimes that can cause problems.
