Moritani 1979 经典

Moritani & deVries 1979 (Am J Phys Med) is one of the foundational papers of strength training science. Design: college students did resistance training for 8 weeks, with strength gains and muscle cross-sectional area (CSA, ultrasound) measured to compare their relative contributions.

Results:

Weeks 1–4: strength ↑50–80%, but CSA increased <5%. The overwhelming majority of early strength gain is neural.Weeks 4–8: strength continued to rise, CSA began meaningful growth; the neural vs hypertrophy contribution gradually flipped.After 2 months: further strength gain came primarily from muscle hypertrophy.
When a beginner says 'I feel stronger but the mirror hasn't changed', it's not an illusion — it's the real physiology. Not seeing muscle in the first 6 weeks is normal; neural adaptation is the prelude to hypertrophy.
