Implication

Demonstrates the relationship between load-velocity and 1RM estimation in untrained early-adolescent females, highlighting its implications for youth training.

Key Points

To investigate the load–velocity relationship and estimate one-repetition maximum (1RM) in untrained early-adolescent females.
Conducted two progressive loading tests followed by actual 1RM attempts on thirty-four untrained females ages 10–14.
Recorded mean propulsive velocity (MPV) to model the load-velocity relationship.
Tested three minimum velocity thresholds (MVT) to estimate 1RM: Actual, General, and Optimal.
MPV exhibited a near-linear decrease with increasing load, with a median R2 of approximately 0.996.
1RM estimates from Actual and General MVTs overestimated actual 1RM by an average of +5.1 kg.
Using an individualized Optimal MVT, bias was removed, showing a +0.6 kg difference from actual 1RM.
