Jiménez-Alonso, A, García-Ramos, A, Cepero, M, Miras-Moreno, S, Rojas, FJ, and Pérez-Castilla, A. Velocity performance feedback during the free-weight bench press testing procedure: An effective strategy to increase the reliability and one repetition maximum accuracy prediction. J Strength Cond Res 36(4): 1077-1083, 2022-This study aimed to determine whether the verbal provision of velocity performance feedback during the free-weight bench press (BP) exercise influences (a) the within-session reliability and magnitude of mean concentric velocity (MCV) values recorded against a range of submaximal loads and (b) the accuracy of the individualized load-velocity profile to estimate the BP 1 repetition maximum (1RM).

Pestaña-Melero, FL, Jaric, S, Pérez-Castilla, A, Rojas, FJ, and García-Ramos A. Comparison of mechanical outputs between the traditional and ballistic bench press: role of the type of variable. J Strength Cond Res 34(8): 2227-2234, 2020-This study aimed to comprehensively explore the differences in mechanical outputs between the bench press (BP) and the bench press throw (BPT) exercises performed by 21 men (age: 22.

This study aimed to compare the between-session reliability of the load-velocity relationship between (1) linear versus polynomial regression models, (2) concentric-only versus eccentric-concentric bench press variants, as well as (3) the within-participants versus the between-participants variability of the velocity attained at each percentage of the 1-repetition maximum. The load-velocity relationship of 30 men (age: 21.2 [3.

Purpose: This study compared the concurrent validity and reliability of previously proposed generalized group equations for estimating the bench press (BP) 1-repetition maximum (1RM) with the individualized load-velocity relationship modeled with a 2-point method.

Methods: Thirty men (BP 1RM relative to body mass: 1.08 [0.

Purpose: To compare the load-velocity relationship between 4 variants of the bench-press (BP) exercise.

Methods: The full load-velocity relationship of 30 men was evaluated by means of an incremental loading test starting at 17 kg and progressing to the individual 1-repetition maximum (1RM) in 4 BP variants: concentric-only BP, concentric-only BP throw (BPT), eccentric-concentric BP, and eccentric-concentric BPT.

Results: A strong and fairly linear relationship between mean velocity (MV) and %1RM was observed for the 4 BP variants (r > .

The aim of the present work is to examine the differences between two groups of fencers with different levels of competition, elite and medium level. The timing parameters of the response reaction have been compared together with the kinetic variables which determine the sequence of segmented participation used during the lunge with a change in target during movement. A total of 30 male sword fencers participated, 13 elite and 17 medium level.

The aim of this study was to determine how much the predicted distance of a hammer throw is affected by (1) ignoring air resistance and (2) assuming that the centre of mass of the hammer coincides with the centre of the ball. Three-dimensional data from actual throws (men: 72.82 +/- 7.
