Testoteron-Zunahme durch Training......

.....mit freien Gewichten im Vergleich zu Maschinentraining:


Results showed that testosterone increased more than 50 percent more following squat training than the leg press workout. Growth hormone also increased more than three times more in the squat trial than the leg press exercise.

Cortisol increased more in the squat trial, although this value was not considered statistically significant. In addition, the testosterone-to-cortisol ratio was much more favorable in the squat trial due to the large testosterone response, which suggests that the anabolic benefits of free weight training are dramatic.

Other differences included total work—the squat trial required much more work and a greater corresponding energy requirement than the leg press. Blood lactate was also about 50 percent higher in the squat trial than the leg press workout.

Researchers acknowledge that the leg press is not an exact match for the barbell squat in terms of movement patterns, range of motion, and stability requirements, which is, of course, the point.
