Using a single, universal velocity loss (VL) threshold to prescribe resistance training volume is unreliable and fails to control the actual amount of work completed across individuals.
Do not use a single, fixed velocity loss threshold (like stopping at 20% velocity loss) to dictate your training volume for everyone. The study shows that men, women, and individuals with different personality traits (like emotional stability) perform different numbers of reps to reach the same velocity loss. To control volume accurately, you must individualize the threshold based on sex, training history, and strength levels, or accept that the volume will vary significantly.
The findings of the present study question the utility of using VL thresholds to prescribe RT volume as the agreement in the amount of work completed across two consecutive testing sessions was not acceptable.
Why this rating
Controlled laboratory study with 51 participants, but limited to back squat and short-term reliability testing.
