Abstract
24 25
The purpose of the present study was to evaluate the changes in movement velocity during
26
resistance training with different loads while the trainees are attempting to move the load at a
27
pre-determined repetition duration. Twenty-one resistance-trained men (age: 25.7 ± 5 years;
28
height: 177.0 ± 7.2 cm; mass: 85.4 ± 13.56 kg) volunteered to participate in the study.
29
Participants performed two test sessions. The first to determine 1 repetition maximum (1RM)
30
load, and the second to evaluate velocity loss during a set to failure performed at 75% and
31
50% of 1RM using a 2 second concentric and 2 second eccentric repetition duration,
32
controlled by a mobile app metronome. When using 75% 1RM there was a significant loss of
33
movement velocity between the antepenultimate and the penultimate repetition (5.33%,
