Final answer:
Hypertrophic factors are primarily responsible for strength gains in children, not neurological factors.
Step-by-step explanation:
Neurological factors as opposed to hypertrophic factors are not primarily responsible for strength gains in children. Hypertrophic factors, such as muscle mass and size, play a larger role in strength gains in children.
During childhood, neurological factors do contribute to strength gains to some extent, but the overall increase in strength is primarily driven by hypertrophic factors.
