Physical actions and work-rest time in men's beach volleyball

Abstract

The purpose of this study was to assess the ball contacts, jumps, hits, work time, and rest ratio in male beach volleyball players in relation to their tactical roles. The sample of this study included 6970 rallies played by 91 beach volleyball players, which corresponded to 179 sets of the 2008 Men's Beach Volleyball World Tour (FIVB). We analyzed: ball contacts, jumps, hits, work time, rest time, set (first, second or third), and player's tactical role (e.g., defense specialist, blocker, or no specialization). A significantly higher number of jumps were executed by blockers. No differences were found in the third set for any of the physical variables studied. This paper provides references about the physical demands (e.g., contacts, jumps, and hits for blockers and defense specialists) and temporal patterns of the beach volleyball game (i.e., work and rest time) for two-set matches and three-set matches.Resumo-"Ações físicas e intervalo trabalho-descanso em voleibol de praia masculino." O objetivo do presente estudo foi avaliar o número de contatos com a bola, saltos, ataques, tempo de trabalho e descanso em jogadores de voleibol de praia masculino em função da sua especialização. A amostra do estudo foi composta por 6970 rallies, jogados por 91 participantes, correspondendo a 179 sets do Beach Volleyball World Tour (FIVB) de 2008. As variáveis estudadas foram: contatos com a bola, saltos, ataques, tempo de trabalho, tempo de descanso, set (1º, 2º e 3º) e especialização do jogador (defensor especialista, bloqueador, ou não especializado). Um número significativo de saltos foi realizado pelos bloqueadores. Não foram encontradas diferenças significativas no 3º set para qualquer uma das variáveis estudadas. Este estudo apresenta valores de referência acerca das demandas físicas (contatos, saltos e ataques realizados por bloqueadores e defensores especialistas) e dos padrões temporais do jogo de voleibol de praia (tempo de trabalho e descanso) para jogos de dois e três sets. Palavras-chave: rendimento, padrões temporais, padrões físicosResumen-"Acciones físicas y tiempos de trabajo-descanso en voley-playa masculino."

La muestra de estudio estuvo compuesta por 6970 jugadas realizadas por 91 jugadores participantes en 179 sets de la Beach Volleyball World Tour (FIVB) de la temporada 2008. Las variables registradas fueron contactos realizadas, saltos, golpeos, tiempo trabajo, tiempo de descanso, set (1º, 2º, o 3º), and función de juego (bloqueador, especialista en defensa, o universal). Un significativo mayor número de saltos fueron realizados por los bloqueadores. No se encontraron diferencias en el tercer en ninguna de las variables físicas estudiadas.

Effects of Experimental Volleyball Rules Quantified by Type and Number of Jumps, Hits and Contacts

“…In beach volleyball, Palao et al (2014) found no statistical difference between ingame roles for average jumps, contacts and hits per play. Marcelino et al (2010) reported significant differences for contacts.…”

“…Almujahed, Ongor, Tigmo, and Sagoo (2013) equated all touches of the ball as follows: serve and attack with hits, and reception, set, block and dig-defense with contacts. Others associated them individually: serve with hit (Lidor & Mayan, 2005;López, 2013); reception, set, block and dig-defense with contact (Afonso et al, 2012;Palao et al, 2014); and attack with hit (Palao et al, 2014). In this study, every touch of the ball during the point is divided into one of two basic groups: hits and contacts.…”

“…In a beach volleyball study (Palao, Valadés, Manzanares, & Ortega 2014), the authors did not specifically define which touches corresponded to hits and contacts. Almujahed, Ongor, Tigmo, and Sagoo (2013) equated all touches of the ball as follows: serve and attack with hits, and reception, set, block and dig-defense with contacts.…”

Effects of Tested Rules on Work-Rest Time in Volleyball

“…A comparison of the results with rally duration in other net and wall sports shows that volleyball is somewhere in the middle. In tennis the rally lasts 5-7 seconds (Kovacs, 2004;Smekal et al, 2001), in badminton 6.2 seconds (Férnandez-Férnandez, de la Aleja-Téllez, Moya-Ramón, CabelloManrique, & Méndez-Villanueva, 2013), in beach volleyball 7.25 seconds (Palao et al, 2014) and in squash 18.6 seconds (Girard et al, 2007).…”

“…This difference is related to the specialization by playing position, because in teams where roles changed there is no such differentiation (Palao, Gutierrez, & Frideres, 2008). Consequently, according to the literature that states that the tactical roles are set depending on the physical capacity of the players (Palao, Valadés, Manzanares, & Ortega, 2014), the optimal game model assumes the combination of high-blocker and lower but agile defender (Kim, Yusof, Lam, Fauzee, & Kwong, 2012).…”
