Contrast Tempo of Movement and Its Effect on Power Output and Bar Velocity During Resistance Exercise (vol 11, 629199, 2021)
Abstract
In the original article as published in the "Materials and Methods" and the "Experimental Sessions" section, the slow movement tempo description was incorrectly written as "5/0/5/0". The correct description should be written as "5/0/X/0".
The correct paragraphs are below: "The researchers examined the impact of different movement tempo distribution during a single set of the bench press exercise on power output and bar velocity. The experiment was performed following a randomized crossover design, where each subject performed three different testing protocols in random and counterbalanced order, one week apart: with an explosive movement tempo in each of three repetitions (E/E/E = explosive, explosive, explosive); with slow tempo of movement in the first repetition and explosive one in the next two repetitions (S/E/E = slow, explosive, explosive); and with a slow tempo of movement in the first two repetitions and explosive tempo in the last repetition of the set (S/S/E = slow, slow, explosive).
The slow repetitions were performed with a 5/0/X/0 movement tempo, while the explosive repetitions were performed with an X/0/X/0 movement tempo. During each experimental session, the participants performed one set of three repetitions at 60%1RM.
Before the main tests, one familiarization session was allowed. One week before the first main session, maximal bench press strength (1 repetition maximum-1RM) was evaluated.
The following variables were measured only in the third repetition using a linear position transducer: peak power output (PP), mean power output (MP), peak bar velocity (PV) and mean bar velocity (MV). All testing sessions were performed in the Strength and Power Laboratory at the Academy of Physical Education in Katowice, Poland."
