Housh, D. J., Housh, T. J., Weir, J. P., & Weir, L. L. (1995). Effect of eccentric dynamic constant external resistance training on the concentric isokinetic torque-velocity curve. Medicine and Science in Sports and Exercise, 27(5), Supplement abstract 117.

This study showed that the nature of a strength training stimulus (dynamic constant external resistance) only improved strength performances in its training exercises and testing activities. This supported the notion of specificity of testing and training. Concentric isokinetic testing was not sensitive to changes brought about by eccentric training.

Implication. Strength training is more likely to benefit the activities which are used for training than other forms of activity. Strength training effects are particularly specific.
