I just ran through a number of articles in Google Scholar on testosterone levels and weight lifting. Most of the talk of exercise raising T levels goes back to a 1993 article where the subjects were youg men who had been lifting weights on a program for more than two years. Yep, their testosterone levels went up after lifting. However, in older men (25+) or in young men that were not extremely physically fit (and there were multiple articles on this), there was little, if any change. Still, I wanted to know how long the elevation would persist.
I pulled this out of one article - "Anabolic hormones such as testosterone and the superfamily of growth hormones (GH) have been shown to be elevated during 15–30 minutes of post-resistance exercise providing an adequate stimulus is present. Protocols high in volume, moderate to high in intensity, using short rest intervals and stressing a large muscle mass, tend to produce the greatest acute hormonal elevations (e.g. testosterone, GH and the catabolic hormone cortisol) compared with low-volume, high-intensity protocols using long rest intervals." I'm guessing that "adequate stimulus" would go along with fitness level and possibly age.
It's 15-30 minutes of elevated hormones under conditions that favor elevation. That probably isn't a problem.
Interesting.
I decided to go the resistance band route tonight. Went to Walmart and got a glout band, standard 25 pound band (for squats), jump rope, and a body ball.
100 reps with the glout band.
6 minutes of jump rope (2 minute intervals)
3 sets of 15 of squats
3 sets of 25 crunches with body ball.
Started with jump rope to get my heart rate up; then went into glout band set; went back to jump rope. switched back and fourth between sets. Then did the rest. My thighs feel like jello.
Any of you gals had luck with the bands? I'm going to increase my sets as the weeks go on till i hit a max.
I'm thinking what I will do is increase my carb intake and hit these bands and jump rope in the morning or night for a hour. Carbs will give me some fat while the bands should tone? Seems like it would work?
