Resistance training performed under a partial range of motion elicits favorable hormonal responses in untrained young men.

Studied

Acute hormone and metabolic responses to full versus partial range-of-motion resistance exercise.

Who / model

Ten untrained young men completed squat and bench-press sessions under full-range, partial-range and resting conditions, separated by one week. Blood was measured immediately and 15 minutes afterward.

Studied dose & schedule

Dose and schedule have not yet been extracted for this summary.

Found

Testosterone rose immediately after both exercise conditions, but remained above baseline at 15 minutes only after partial-range exercise. Lactate rose more after full-range exercise. Cortisol remained elevated at 15 minutes only after full-range exercise.

Limits

This small, short-term experiment measured blood responses, not long-term muscle growth or strength. It cannot establish that the hormone pattern improves training results.
