The human aging process, characterized by time-dependent and progressive deterioration of the body’s physiological function ( López-Otín, Blasco, Partridge, Serrano, & Kroemer, 2013 ), is linked to several changes, such as increased body fat, reduced skeletal muscle mass, and decline in physical

The preservation and promotion of skeletal muscle mass and strength is essential for athletes and nonathletes alike; whether the goal is improved performance or maintaining one’s quality of life. Sufficient skeletal muscle is required for functional movement and also plays a vital role in whole

, type 2 diabetes, functional disability, and premature death. 1 Skeletal muscle accounts for 40% of total body mass and is the main determinant of energy expenditure among sedentary individuals. Although regular physical activity is fundamental for preserving skeletal muscle mass, strength and function

involved in the process of glycogen synthesis. Adenosine monophosphate-activated protein kinase (AMPK) is an enzyme responsible for the translocation of glucose transporter 4 (GLUT-4) to the cell membrane when activated by skeletal muscle contraction ( Mu et al., 2001 ; Stapleton et al., 1996 ). AMPK

The role of increased dietary protein intake in facilitating skeletal muscle adaptations associated with endurance training is now gaining acceptance ( Moore et al., 2014 ). Indeed, consuming protein before ( Coffey et al., 2011 ), during ( Hulston et al., 2011 ), and/or after ( Rowlands et

The Drinkwater four-way fractionation model uses the unisex phantom model to partition total body mass into four compartments—FM, skeletal muscle mass (SMM; intramuscular adipose tissue included), bone mass, and residual mass ( Drinkwater
