Mazzetti, S. A., Volek, J. S., Duncan, N. D., Ratamess, N. A., Wickham, R. B., McGuigan, M. R., Nindl, B. C., Mazzetti, H. M., Scheett, T. P., & Kraemer, W. J. (2001). Influence of supervision of strength training on testosterone:cortisol ratio. Medicine and Science in Sports and Exercise, 33(5), Supplement abstract 1526.
Hormonal adaptations to strength training were measured in trained college-age males. Training (12 weeks) occurred in supervised (N = 8) and unsupervised (N = 7) conditions.
Increases in testosterone:cortisol ratio, fat-free mass, and strength performance were greater in the supervised group.
Implication. Supervised strength training produces more gains than does unsupervised training.
