Perception of changes in bar velocity as a resistance training monitoring tool for athletes

To investigate if perception of changes in bar velocity (PCV) can be used as a substitute for tracking devices commonly to monitor resistance-exercises. Twenty-one professional male soccer athletes (21±4 years) first went through load-power profile assessment determine their optimal power load the back-squat. In next three experimental sessions, completed four sets six repetitions loaded with load. Starting from second repetition, reported PCV each repetition percentage repetition. Accuracy was calculated absolute difference between and actual change measured linear-encoder. The fourth sessions served pre- post-intervention which received no feedback about accuracy. third session intervention session, verbal visual accuracy levels after set. estimated decreased an average error 7% pre-intervention 4.7% (95% confidence difference: 1.5, 3.0). Athletes based training experience begin reasonable rates meaningfully improved single that includes feedback. When are impractical or absent, implemented resistance monitoring tool.
