What is the predominant factor causing increases in strength during the initial weeks of training?

Question

Quizplus · Accepted Answer

During the initial weeks of training, improvements in neuromuscular adaptation are the predominant factor causing increases in strength. This is because the body is learning how to better recruit and coordinate motor units (bundles of muscle fibers) to perform the exercise, leading to greater force production without necessarily increasing muscle size. As training progresses beyond this initial phase, muscle size and fiber cross-sectional area become increasingly important factors in strength gains.
