Effect of physical activity on IGF-1 and IGFBP levels in the context of civilization diseases prevention
Journal Title: Roczniki Państwowego Zakładu Higieny - Year 2016, Vol 67, Issue 2
Abstract
Background. Insulin-like growth factor 1 (IGF-1) is known as somatomedin C. This polypeptide hormone is functionally and structurally similar to insulin. IGF-1 effects on tissue by the IGF-1R and the insulin-like growth factor-binding protein also known as IGFBP. Abnormal IGF-1 and IGFBP signaling are positively correlated with a high risk of selected civilization diseases development. Physical inactivity is a one of the main causes of majority of chronic diseases and it is associated with eg. IGF-1 and IGFBPs level. Objective. The aim of the study was to explanation the effect of physical activity on IGF-1 and its binding protein – IGFBPs concentration in the context of selected civilization diseases prevention. The review of clinical trial. Material and Methods. The review of articles had published in databases: MEDLINE, EMBASE, Scopus and Web of Science until December 2015. The selected prospective studies about the effect of exercise on IGF-1 level and its binding protein IGFBP in the context of selected civilization diseases prevention were collected. Results. The majority of the included studies indicate that mechanical loading is a key mechanism linking IGF-1/IGFBPs concentration and selected chronic diseases development. The duration and intensity of physical activity have a significant impact on IGF-1 and IGFBP serum. The highest concentration of IGF-1 in serum was after eccentric training. “Overtraining” increases unfavorable and unbound IGF-1 levels and contributes to the increased incidence of hormone-cancer and osteoarthritis. Conclusions. Irregularity of the GH/IGF-1 axis may affect on the development of rheumatic diseases, cardiovascular diseases (regulate cardiac growth and metabolism) and metabolic syndrome.
