• Role of the nervous system in sarcopenia and muscle atrophy with aging: strength training as a countermeasure (2010, background): “Similar to that seen in young individuals (Aagaard et al., 2001), adaptive changes in muscle architecture can be observed in elderly subjects in response to heavy-resistance strength training.”
• The effects of eccentric versus concentric resistance training on muscle strength and mass in healthy adults: a systematic review with meta-analysis (2008, background): “over longer durations, increases in strength are strongly correlated to adaptations in muscle mass.”
• Increased rate of force development and neural drive of human skeletal muscle following resistance training. (2002, methodology): “In addition, muscle fiber pennation angle also increased, which allowed for a marked increase in physiological muscle-fiber area, with a resulting rise in maximal contractile force (2).”
• Developing Maximal Neuromuscular Power (2011, background): “[19] The differences in peak power per unit CSA are due to differences in specific force (i.e. Fmax/CSA), Vmax and the curvature of the forcevelocity curve amongst the fibre types.”
• The Importance of Muscular Strength in Athletic Performance (2016, background): “As changes in muscle architecture [20, 254] and tendon stiffness [275, 276] may affect the electromechanical delay and rate of force development during stretch-shortening cycle tasks, it is important to note the time needed for positive training adaptations to occur.”
• Neural adaptation to resistance training: changes in evoked V-wave and H-reflex responses. (2002, background): “Such changes include increases in anatomical muscle cross-sectional area (2, 29) and physiological muscle fiber area (3, 14, 44), increased percentage 2A fibers with a corresponding decrease in 2X fibers (3, 14), and steeper muscle fiber pennation angles (2).”
• Developing Maximal Neuromuscular Power (2011, background): “Whole muscle cross-sectional area (CSA) would be considerably greater([35-56]) as a result of increased myofibrillar CSA of type I and, to a greater degree, type II fibres.”
• Early skeletal muscle hypertrophy and architectural changes in response to high-intensity resistance training. (2007, result): “This finding is in line with previous reports of an increase in fascicle length and pennation angle with strength training (1, 9).”
