Genetics and physical activity among elderly Brazilian women: Responses to exercise in relation to polymorphisms in the IGF-2 genes and variation in muscle mass and strength phenotypes

It is well established that the human ageing process is associated with a significant decline in neuromuscular function and performance. Studies involving twins suggest that genetic factors partly explain inter-individual variation in fat-free mass (FFM) and muscle strength. Assessment of the association between IGF-2 gene polymorphism and muscle mass and strength phenotypes in older women before and after resistance training.
