A comprehensive analysis of the velocity-based method in the shoulder press exercise: stability of the load-velocity relationship and sticking region parameters
(Termedia Publishing, 2020-08-31) Hernández Belmonte, Alejandro; García Pallarés, Jesús; Martínez Cava, Alejandro; Morán Navarro, Ricardo José; Courel Ibáñez, Javier; Actividad Física y Deporte
The purpose of this study was threefold: i) to analyse the load-velocity relationship of the shoulder press (SP) exercise, ii) to investigate the stability (intra-individual variability) of this load-velocity relationship for athletes with different relative strength levels, and after a 10-week velocity-based resistance training (VBT), and iii) to describe the velocity-time pattern of the SP: first peak velocity [Vmax1], minimum velocity [Vmin], and second peak velocity [Vmax2]. This study involves a cross-sectional (T1, n = 48 subjects with low, medium and high strength levels) and longitudinal (T2, n = 24 subjects randomly selected from T1 sample) design. In T1, subjects completed a progressive loading test up to the 1RM in the SP exercise. The barbell mean, peak and mean propulsive velocities (MV, PV and MPV) were monitored. In T2, subjects repeated the loading test after 10 weeks of VBT. There were very close relationships between the %1RM and velocity attained in the three velocity outcomes (T1, R2: MV = 0.970; MPV = 0.969; PV = 0.954), being even stronger at the individual level (T1, R2 = 0.973–0.997). The MPV attained at the 1RM (~0.19 m·s-1) was consistent among different strength levels. Despite the fact that 1RM increased ~17.5% after the VBT programme, average MPV along the load-velocity relationship remained unaltered between T1 and T2 (0.69 ± 0.06 vs. 0.70 ± 0.06 m·s-1). Lastly, the three key parameters of the velocity-time curve were detected from loads > 74.9% 1RM at 14.3% (Vmax1), 46.1% (Vmin), and 88.7% (Vmax2) of the concentric phase. These results may serve as a practical guideline to effectively implement the velocity-based method in the SP exercise.

Análisis de la validez de las ecuaciones de estimación del 1RM con técnica de parada: una nueva propuesta
(Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2017) Martínez Cava, Alejandro; Morán Navarro, Ricardo José; García Pallarés, Jesús; Facultades, Departamentos, Servicios y Escuelas::Facultades de la UMU::Facultad de Ciencias del Deporte
El objetivo de esta investigación es validar nuevas ecuaciones de regresión para estimar el valor de fuerza dinámica máxima absoluta (1RM) mediante test de máximo número de repeticiones hasta el fallo muscular (nRM) ejecutados con técnica de parada o stop. Igualmente, se estudian los niveles de validez que presentan las ecuaciones que ya se encuentran actualmente definidas en la literatura internacional para estimar la mag- nitud de la carga (%1RM) y el valor de 1RM a partir de un test nRM en ejecuciones con técnica de parada. Los resultados indican que las nuevas ecuaciones propuestas en esta investigación [1RM en Press Banca = masa desplazada en kg (-0,01841*nRM)+0,981; 1RM en Sentadilla Completa = masa desplazada en kg (-0,01176*nRM)+0,975]muestran indicadores sus- tancialmente mejores de validez(ET = 1,8-2,2 kg; R2 = 0,956-0,988), y por lo tanto de mayor capacidad predictiva, que el resto de ecuaciones definidas en la literatura internacional hasta la fecha.

Efecto de la bajada de peso y la competición sobre el perfil de estado de ánimo en deportes de combate
(Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2015) Martínez Abellán, Alberto; Morán Navarro, Ricardo José; López Gullón, José María; García Pallarés, Jesús; Cruz Sánchez, Ernesto de la; Ortín Montero, Francisco José
El propósito de este estudio ha sido describir los cambios que sufre el estado de ánimo que presentan los deportistas de combate durante las fases de bajada de peso y su posterior recuperación antes del comienzo de los eventos competitivos prioritarios de la temporada. Un total de 105 hombres y mujeres especialistas en las modalidades de combate de lucha olímpica, taekwondo y boxeo fueron pesados y contestaron la versión abreviada del Perfil de Estados de Ánimo (POMS) entre 30 y 60 minutos antes del pesaje oficial (PRE) y entre 30 y 60 minutos antes del comienzo del primer combate (POST) de sus respectivos campeonatos nacionales. Los resultados demostraron que las hubo mejoras significativas (p < .05) en las dimensiones de Cólera, Fatiga y Depresión, aunque estos cambios no parecen estar relacionados con la variación porcentual de la masa corporal que experimentan los deportistas durante este mismo periodo (r < .261). Estos hallazgos nos indican que las 12-18 horas que separan el pesaje oficial y el comienzo del torneo en deportes de combate propician mejoras sustanciales en sus estados de ánimo, aunque estos cambios parecen ser independientes de sus fluctuación de la masa corporal.

Effect of pause versus rebound techniques on neuromuscular and functional performance after a prolonged velocity-based training
(Human Kinetics, 2021) Martínez Cava, Alejandro; Hernández Belmonte, Alejandro; Courel Ibáñez, Javier; Conesa Ros, Elena; Morán Navarro, Ricardo José; García Pallarés, Jesús; Actividad Física y Deporte
Purpose: A variation of the traditional squat (SQ) rebound technique (REBOUND) including a momentary pause ∼2 seconds (PAUSE) between eccentric and concentric phases has been proposed. Although there is a consensus about the lower acute effects on performance of this PAUSE variant compared with traditional REBOUND technique, no information exists about the differences in longitudinal adaptations of these SQ executions. Methods: A total of 26 men were randomly assigned into the PAUSE (n = 13) or REBOUND (n = 13) groups and completed a 10-week velocity-based training using the SQ exercise, only differing in the technique. Neuromuscular adaptations were assessed by the changes in the 1-repetition maximum strength and mean propulsive velocity achieved against the absolute loads (in kilograms) common to pretest and posttest. Functional performance was evaluated by the following tests: countermovement jump, Wingate, and sprint time at 0 to 10, 10 to 20, and 0 to 20 m. Results: Whereas both groups showed significant increases in most of the neuromuscular tests (P < .05), the PAUSE (effect size [ES] = 0.76-1.12) presented greater enhancements than REBOUND (ES = 0.45-0.92). Although not significant, improvements in Wingate and sprint time at 0 to 10 and 0 to 20 m were higher for PAUSE (ES = 0.31-0.46) compared with REBOUND (ES = 0.10-0.29). Conversely, changes on countermovement jump and sprint time at 10 to 20 m were superior for REBOUND (ES = 0.17-0.88) than for PAUSE (ES = 0.09-0.75). Conclusion: Imposing a pause between eccentric and concentric phases in the SQ exercise could be an interesting strategy to increase neuromuscular and functional adaptations in sport actions that mainly depend on concentric contractions. Moreover, sport abilities highly dependent on the stretch-shortening cycle could benefit from the REBOUND or a combination of the 2 techniques.

El sistema de categorías por peso que rige los deportes de comba- te fomenta en estos atletas la puesta en práctica de determinados métodos y estrategias para reducir su masa corporal antes del pesaje ocial, así como otros hábitos y protocolos de rápida rehidratación y rellenado de las reser- vas energéticas en el lapso de tiempo (6-20 h) que separa este pesaje ocial del comienzo del torneo. El objetivo de este trabajo fue diseñar y validar por primera vez un instrumento que permita estudiar los hábitos que están llevando a cabo los deportistas de combate durante las fases de pérdida de peso y su posterior recuperación antes del torneo. Tras el diseño original del cuestionario, se vericó la validez de contenido y la validez estructural del instrumento a través del acuerdo y consenso de 12 jueces expertos. En segundo lugar, se realizó un estudio de la validez de compresión de los ítems que compone el instrumento con una muestra de 46 deportistas de combate experimentados. Así mismo, se calculó la abilidad mediante la aplicación de la prueba test-retest en una muestra de 28 deportistas. Los resultados indicaron que el cuestionario sobre pérdida de peso en deportes de combate presenta óptimos niveles de validez de contenido así como de re- producibilidad en las respuestas para identicar y monitorizar los métodos, las frecuencias y las estrategias con las que estos deportistas acometen las fases de pérdida de peso antes del pesaje y su posterior recuperación antes del comienzo del torneo.

Velocity and power load relationships in the hal parallel and full back squat
(2018) Sánchez-Medina, Luis; González-Badillo, Juan José; Martínez Cava, Alejandro; Morán Navarro, Ricardo José; García Pallarés, Jesús; Actividad Física y Deporte; Facultades de la UMU::Facultad de Ciencias del Deporte
This study aimed to compare the load-velocity and load-power relationships of three common variations of the squat exercise. 52 strength-trained males performed a progressive loading test up to the one-repetition maximum (1RM) in the full (F-SQ), parallel (P-SQ) and half (H-SQ) squat, conducted in random order on separate days. Bar velocity and vertical force were measured by means of a linear velocity transducer time-synchronized with a force platform. The relative load that maximized power output (Pmax) was analyzed using three outcome measures: mean concentric (MP), mean propulsive (MPP) and peak power (PP), while also including or excluding body mass in force calculations. 1RM was significantly different between exercises. Load-velocity and load-power relationships were significantly different between the F-SQ, P-SQ and H-SQ variations. Close relationships (R2=0.92-0.96) between load (%1RM) and bar velocity were found and they were specific for each squat variation, with faster velocities the greater the squat depth. Unlike the F-SQ and P-SQ, no sticking region was observed for the H-SQ when lifting high loads. The Pmax corresponded to a broad load range and was greatly influenced by how force output is calculated (including or excluding body mass) as well as the exact outcome variable used (MP, MPP, PP).

Reliability of technologies to measure the barbell velocity: Implications for monitoring resistance training
(2020-06-10) González-Badillo, Juan José; Martínez Cava, Alejandro; Hernández Belmonte, Alejandro; Courel Ibáñez, Javier; Morán Navarro, Ricardo José; García Pallarés, Jesús; Actividad Física y Deporte; Facultades de la UMU::Facultad de Ciencias del Deporte
This study investigated the inter- and intra-device agreement of four new devices marketed for barbell velocity measurement. Mean, mean propulsive and peak velocity outcomes were obtained for bench press and full squat exercises along the whole load-velocity spectrum (from light to heavy loads). Measurements were simultaneously registered by two linear velocity transducers T-Force, two linear position transducers Speed4Lifts, two smartphone video-based systems My Lift, and one 3D motion analysis system STT. Calculations included infraclass correlation coefficient (ICC), Bland-Altman Limits of Agreement (LoA), standard error of measurement (SEM), smallest detectable change (SDC) and maximum errors (MaxError). Results were reported in absolute (m/s) and relative terms (%1RM). Three velocity segments were differentiated according to the velocity-load relationships for each exercise: heavy (� 80% 1RM), medium (50% < 1RM < 80%) and light loads (� 50% 1RM). Criteria for acceptable reliability were ICC > 0.990 and SDC < 0.07 m/s (~5% 1RM). The T-Force device shown the best intra-device agreement (SDC = 0.01–0.02 m/s, LoA <0.01m/s, MaxError = 1.3–2.2%1RM). The Speed4Lifts and STT were found as highly reliable, especially against lifting velocities �1.0 m/s (Speed4Lifts, SDC = 0.01–0.05 m/s; STT, SDC = 0.02–0.04 m/s), whereas the My Lift app showed the worst results with errors well above the acceptable levels (SDC = 0.26–0.34 m/s, MaxError = 18.9–24.8%1RM). T-Force stands as the preferable option to assess barbell velocity and to identify technical errors of measurement for emerging monitoring technologies. Both the Speed4Lifts and STT are fine alternatives to T-Force for measuring velocity against high-medium loads (velocities � 1.0 m/s), while the excessive errors of the newly updated My Lift app advise against the use of this tool for velocity-based resistance training.

Bench Press at Full Range of Motion Produces Greater Neuromuscular Adaptations Than Partial Executions After Prolonged Resistance Training
(2019) González-Badillo, Juan J.; Martínez Cava, Alejandro; Hernández Belmonte, Alejandro; Courel Ibáñez, Javier; Morán Navarro, Ricardo José; García Pallarés, Jesús; Actividad Física y Deporte; Facultades de la UMU::Facultad de Ciencias del Deporte
Martínez-Cava, A, Hernández-Belmonte, A,Courel-Ibáñez, J,Morán-Navarro, R,González-Badillo, JJ, and Pallarés, JG. Bench press at full range of motion produces greater neuromuscular adaptations than partial executions after prolonged resistance training. J Strength Cond Res XX(X): 000–000, 2019—Training at a particular range of motion (ROM) produces specific neuromuscular adaptations. However, the effects of full and partial ROM in one of the most common upper-limb exercises such as the bench press (BP) remain controversial. In this study, 50 recreationally to highly resistance trainedmen were randomly assigned to 1 of 4 training groups: full bench press (BPFULL), two-thirds bench press (BP2/3), and one-third bench press (BP1/3) and control (training cessation). Experimental groups completed a 10-week velocity-based resistance training program using the same relative load (linear periodization, 60–80% 1 repetition maximum [1RM]), only differing in the ROM trained. Individual ROM for each BP variation was determined in the familiarization and subsequently replicated in every lift during training and testing sessions. Neuromuscular adaptations were evaluated by 1RMstrength and mean propulsive velocity (MPV). The BPFULL group obtained the best results for the 3 BP variations (effect size [ES]50.52–1.96); in turn, partialBP produced smaller improvements as theROMdecreased (BP2/3: ES50.29–0.78; BP1/3: ES520.01 to 0.66). After 10-week of training cessation, the control group declined in all neuromuscular parameters (ES50.86–0.92) except inMPV against low loads. Based on these findings, the BPFULL stands as the most effective exercise to maximize neuromuscular improvements in recreational and welltrained athletes compared with partial ROM variations.
