Implication

Randomized trial assesses load-velocity profile's ability to predict 1RM in resistance-trained individuals, indicating a feasible alternative for strength assessment.

Key Points

This research aims to evaluate the reliability and validity of a 3-point load-velocity profile for predicting 1 repetition maximum (1RM) in hex bar deadlift.
Nineteen resistance-trained subjects completed two testing sessions: a traditional 1RM test and a submaximal load-velocity assessment.
Reliability was assessed using coefficient of variation and intraclass correlation coefficient.
A linear mixed-effects model predicted 1RM using load-velocity parameters.
L 0 showed excellent reliability (CV = 5.2%, ICC = 0.97), while V 0 was less reliable (CV = 6.0%, ICC = 0.70).
The predictive model explained 97.5% of the variance in actual 1RM (p < 0.05).
Predicted 1RM values were highly similar to actual 1RM values, but limits of agreement were ±15.7 kg.
