Abstract

Summary. This study aimed to verify the differences between the training load planned by coaches and that perceived by Beach Volleyball (BV) players and observe the effects on athletes’ neuromuscular function. Three female BV players and well-known coaches participated in the research and were accompanied for three training weeks in the preseason phase. Rating of perceived exertion (RPE) was collected through the 0-10 scale during a previous training session. Strength, physical fitness and tactical-technical training have been assessed with coaches and athletes’ responses 30 minutes after the end of the session. RPE Session was calculated by the product between the training duration in minutes and RPE, to estimate Internal Training Load (ITL). Neuromuscular function was assessed through Countermovement Jump (CMJ). To verify differences between coaches and athletes’ responses and vertical jump performance were used either the magnitude of differences and clinical inference. Athletes experienced lower RPE and ITL as planned by coaches in the first week of training. CMJ increased substantially from the first to the third week (with likely differences (93/03/04), standardized difference = 1.60 and 90% confidence intervals = 0.00; 3.21). We suggest that training load planned by coaches similar to that perceived by athletes have a concomitant improvement with neuromuscular performance.Resumen. Este estudio tuvo como objetivo verificar las diferencias entre la carga de entrenamiento planificada por los entrenadores y la percibida por los jugadores de voleibol de playa (VP) y observar los efectos sobre la función neuromuscular de los atletas. Tres jugadoras de VP y entrenadores conocidos participaron en la investigación y fueron acompañadas durante tres semanas de entrenamiento en la fase de pretemporada. El valor nominal del esfuerzo percibido (NEP) se recolectó a través de la escala 0-10 durante una sesión de entrenamiento anterior. La fuerza, la forma física y el entrenamiento táctico-técnico se evaluaron con las respuestas de los entrenadores y atletas 30 minutos después del final de la sesión. El producto calculó la sesión de NEP entre la duración del entrenamiento en minutos y el NEP, para estimar la carga interna de entrenamiento (CIE). La función neuromuscular se evaluó mediante salto contramovimiento (SCM). Para verificar las diferencias entre los entrenadores y las respuestas de los atletas y el rendimiento del salto vertical, se utilizó la magnitud de las diferencias y la inferencia clínica. Los atletas experimentaron menos NEP e CIE que fueron planificados por los entrenadores en la primera semana de entrenamiento. SCM aumentó sustancialmente de la primera a la tercera semana (con diferencias probables (93/03/04), diferencia estandarizada = 1.60 e intervalos de confianza del 90% = 0.00; 3.21). Sugerimos que la carga de entrenamiento planificada por entrenadores similar a la percibida por los atletas tenga una mejora concomitante con el rendimiento neuromuscular.

Validity and reliability of My Jump 2® app to measure the vertical jump on elite women beach volleyball players

“…Beach volleyball is a team sport characterized by its intermittent nature, fluctuating randomly from short periods of maximal or sub-maximal activity to long periods of moderate and low-intensity activity ( Arruda & Hespanhol, 2008 ; Magalhães et al, 2011 ; Medeiros et al, 2014 ). This alternating activity nature arise in game actions as jumps, constituting one of the most determining physical-technical elements in beach volleyball performance ( Andrade et al, 2020 ; Medeiros et al, 2014 , 2023 ; Oliveira et al, 2018 ). Accordingly, literature within beach volleyball scope has pointed out that jump measures can help coaches monitor training load and understand the activity profile of players ( Andrade et al, 2020 ; Medeiros et al, 2023 ; Oliveira et al, 2018 ).…”

“…Specifically, the countermovement jump (CMJ) has been one of the most popular tests for assessing and monitoring neuromuscular status in volleyball and beach volleyball ( Andrade et al, 2020 ; Batista, RFd & Guerra, 2008 ; Oliveira et al, 2018 ; Sheppard et al, 2011 ; Sheppard & Newton, 2012 ).…”

Global Position Analysis during Official Elite Female Beach Volleyball Competition: A Pilot Study

“…As a result, researchers have been conducting research on the factors that affect athletes' performance and match outcomes. Previously, some important studies have contributed to the increase in the knowledge of the physiological response [1,2], technical and tactical aspects [3], training load [4][5][6], and match analysis of BV [7][8][9]. Most of the findings revealed that BV is performed intermittently, with brief bouts of high-intensity exercise interspersed by low-intensity periods [10].…”

Effects of Congested Fixture on Men’s Volleyball Load Demands: Interactions with Sets Played

“…The success of the training process and, consequently, of volleyball matches depends on adjustments that balance the magnitude and distribution of training load and recovery [ 12 , 16 ]. Positive relationships were observed between performance in game actions that require powerful vertical jumps (serving, blocking, and attacking) and overall success in matches [ 14 ].…”
