Sedentary behaviors (SB) are characterized by low energy expenditure while in a sitting or
reclining posture. Evidence relevant to understanding the physiology of SB can be derived …

Unaccustomed exercise consisting of eccentric (ie, lengthening) muscle contractions often
results in muscle damage characterized by ultrastructural alterations in muscle tissue …

Background Exercise changes the concentrations of many metabolites, which are small
molecules (< 1.5 kDa) metabolized by the reactions of human metabolism. In recent years …

The risk associated with multiple cancers, cardiovascular disease, diabetes, and all-cause
mortality is decreased in individuals who meet the current recommendations for physical …

Skeletal muscle plays a critical role in physical function and metabolic health. Muscle is a
highly adaptable tissue that responds to resistance exercise (RE; loading) by …

Exercise training in combination with optimal nutritional support is an effective strategy to
maintain or increase skeletal muscle mass. A single bout of resistance exercise undertaken …

Summary Background & Aims Sarcopenia is characterized by the progressive loss of
skeletal muscle mass and function, which reduces mobility and quality of life. Risk factors for …

(1) Background: Several factors have been suggested to be associated with the
physiopathology of frailty in older adults, and nutrition (especially protein intake) has been …

Muscle protein breakdown (MPB) is an important metabolic component of muscle
remodeling, adaptation to training, and increasing muscle mass. Degradation of muscle …

(1) Background: The present work aims to conduct a systematic review and meta-analysis of
observational studies, in order to investigate the association of relative protein intake and …
