Implication

Cross-sectional survey observes distinct limb strength trajectories across youth, indicating hormonal stimuli drive continued male muscular gains after linear growth ceases.

Key Points

To evaluate isometric muscle strength development in upper and lower limbs relative to changes in height and weight during childhood and adolescence.
Conducted a cross-sectional survey measuring standing height, body weight, and isometric strength of the elbow flexor and quadriceps muscles in 267 boys and 284 girls aged 5 to 17 years from private London schools.
Evaluated the mathematical relationship between pre-adolescent muscle strength gains and height to assess the role of mechanical stretch and weight loading.
Elbow flexor and quadriceps strength increased steadily in both boys and girls across all age groups from 8 to 12 years.
Following age 12, boys demonstrated a rapid increase in both quadriceps and elbow flexor strength that persisted even after height and body weight gains had virtually ceased.
Pre-adolescent elbow flexor and quadriceps strength increased as a function of height squared and height cubed, respectively, reflecting long bone elongation and body mass loading as primary mechanical drivers.
