Hormonal
An acute bout of either endurance or resistance exercise significantly increases circulating levels of anabolic hormones (testosterone, estradiol, growth hormone) in females aged 19-69, regardless of chronological age.
If you are a woman between 19 and 69, doing a standard workout (either cardio or weights) will trigger a temporary spike in key anabolic hormones like testosterone and growth hormone. This happens regardless of your age, provided you are reasonably active. You don't need to be an elite athlete to get this hormonal response; typical recreational exercise intensities are sufficient.
Results indicate that an acute bout of exercise can increase concentrations of anabolic hormones in females across a wide age range.
Why this rating
Randomized, balanced design with control group, but small sample size per age quintile (n=6).

More from this paper
- Resistance exercise specifically increases Dehydroepiandrosterone (DHEA) levels, whereas endurance exercise does not significantly change DHEA in females.Good
- Exercise intensity, rather than age, drives the magnitude of the acute hormonal response (testosterone, growth hormone) to exercise in females.Moderate
