Effects of resistance training on insulin-like growth factor-1 and IGF binding proteins

Article Abstract:

This article investigates the effects determining resistance training on circulating insulin-like growth factors (IGF) and on its two binding proteins, and also provides a comparison of the time course of strength changes with that of hormonal changes and determine the extent to which exercise affects growth changes. Results show that increased circulating IGF-1 might mediate the increases in strength coming from resistance training.

Effects of resistance training on insulin sensitivity in overweight Latino adolescent males

Article Abstract:

The effects of a 16-week progressive resistance training intervention on insulin sensitivity in overweight Latino adolescent males at high risk for developing type 2 diabetes are examined. It is concluded that a twice-per-week 16-week resistance program can significantly increase insulin sensitivity in overweight Latino adolescent males independent of changes in body composition.

Isolated heart responsiveness to beta-stimulation after exercise training in obesity

Article Abstract:

Results demonstrate that isolated hearts from obese rabbits show negative effect on responsiveness of the heart to beta-adrenergic stimulation and that this effect is not significantly attenuated following exercise training.
