Why do some people sweat more hormones than others when running?
Sex and training differences in human growth hormone levels during prolonged exercise.

Scientists measured a growth hormone in people running on treadmills and found that trained men and women have different hormone patterns, and women start with more of this hormone than men.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

During prolonged exercise, the intensity of the workout and whether a person is a trained runner or not account for about one-third of the differences in how much growth hormone their body releases.
Women have higher levels of growth hormone at rest and during the first 30 minutes of moderate-intensity treadmill exercise compared to men, regardless of their training background.
Men who regularly train for endurance sports show higher and longer-lasting increases in growth hormone during and after long workouts compared to men who do not train for endurance sports.
In resting conditions, higher estradiol levels correlate with higher growth hormone levels, but during physical exercise, higher estradiol levels correlate with lower growth hormone levels, showing that the relationship between these two hormones changes depending on whether the body is at rest or active.
