The Potential Role Of Selected Body Composition Phenotypes In The Interpretation Of The Exercise-Induced Components Of The Insulin-Like Growth Factor Systems, Gökhan Umutlu, Nevzat Demirci

Baltic Journal of Health and Physical Activity

Introduction: Increased adiposity leads to impaired physiologic growth hormone secretion and low and high body mass index (BMI) values increase health risks. However, BMI only measures results in variations in fat-free mass (FFM), fat-free mass index (FFMI), normalized fat-free mass index (NFMI), and body fat mass (BFM). This study evaluated the insulin-like growth factor system responses to the given exercise and their interaction with the changes in BMI, FFM, FFMI, and NFFMI in healthy male participants. Material and methods: A randomized controlled trial with a parallel groups study design was used. Thirty healthy male participants (age: 21.33 ±1.24 years) were …
