The Utility of IGF-I And IGFBP-3 as Markers of Training Status in Elite Swimmers
The purpose of this study was to assess the effects of long-term swim training on resting levels of IGF-I and IGFBP-3 in elite swimmers. A second objective was to determine if changes in IGF-I or IGFBP-3 were associated with changes in fitness or symptoms of overtraining.
