Effects of low volume resistance and cardiovascular training on strength and aerobic capacity in unfit men and women: a demonstration of a threshold model.

A threshold model postulates that prescriptively applying the appropriate cardiorespiratory and strength stimulus at a designated threshold of intensity for a brief time results in the targeted adaptations. A randomized control group design was used with 17 unfit males and females (mean age = 37.1 +/- 6.
