Anthropometric characteristics and vertical jump abilities by player position and performance level of junior female volleyball players
2021
Although absolute jump heights should be considered an important factor in judging the performance requirements of volleyball players, limited data is available on age-appropriate categories. The purpose of this study is to determine the differences in specific anthropometric characteristics and jumping performance variables in under−19 female volleyball players in relation to playing position and performance level. The sample of subjects consisted of 354 players who prepared for the U19 Women’s Volleyball European Championship 2020 (17.4 ± 0.8 years, 1.81 ± 0.07 m, 67.5 ± 7.1 kg). Playing positions analyzed were setters (n = 55), opposites (n = 37), middle blockers (n = 82), outside hitter…
Resistance Training Acutely Impairs Agility and Spike-Specific Performance Measures in Collegiate Female Volleyball Players Returning from the Off-Se…
2020
This study examined the acute effects of resistance training (RT) on volleyball-specific performance. Sixteen female volleyball players undertook their initial, pre-season RT bout. Countermovement jump (CMJ), delayed onset of muscle soreness (DOMS), and sport-specific performances (i.e., run-up jump, agility, and spiking speed and accuracy) were measured before, 24 (T24), and 48 (T48) hours after RT. A significant increase in DOMS was observed at T24 and T48 (~207.6% ±
Skill-related differences between athletes and nonathletes in speed discrimination.
2008
This study examined differences in decision-making time and accuracy as attributes of speed discrimination between participants skilled and less skilled in ball games. A total of 130 men, ages 18 to 28 years ( M = 21.2, SD = 2.6), participated. The athlete sample (skilled group) comprised Estonian National League volleyball ( n = 26) and basketball players ( n = 27). The nonathlete sample (less skilled group) included 77 soldiers of the Estonian Defence Force with no reported top level experience in ball games. Speed-discrimination stimuli were images of red square shapes presented moving along the sagittal axis at four different virtual velocities on a computer (PC) screen which represent…
Visuospatial attention lateralization in volleyball players and in rowers.
2011
In the present study, differences in visuospatial attention lateralization were evaluated in athletes engaged in open- compared to closed-skill sports and sedentary nonathletes. 23 volleyball players (open skill; Italian national level and regional level), 10 rowers (closed skill, Italian national level), and 23 sedentary participants responded to a computerized line-length judgment task. Five lines, differing in the length of their right and left segments, were randomly presented; the respondent made a forced-choice decision about the respective length of the two segments. Volleyball players responded significantly faster; those at the higher competitive level were also more accurate, mak…
Fitness profile of young female volleyball players
2020
BACKGROUND: Factors that influence performance in volleyball, in terms of motor skills, refer to muscle power, speed and agility. This study aimed to examine the abilities and physical characteristics of female volleyball players in terms of age and player specialization. METHODS: A total of 35 subjects (junior and cadet age), participated in this study. Subjects were assessed for body height, mass, spike and block reach, and body composition. Vertical jump, standing broad jump, spike and block jump were tests used to measure leg power. The running speed was evaluated with a 20-m single-sprint effort. The change of direction speed was assessed with a T-test, the sprint 9-3-6-3-9 m forward-b…
Identifying individuality and variability in team tactics by means of statistical shape analysis and multilayer perceptrons.
2012
Abstract Offensive and defensive systems of play represent important aspects of team sports. They include the players’ positions at certain situations during a match, i.e., when players have to be on specific positions on the court. Patterns of play emerge based on the formations of the players on the court. Recognition of these patterns is important to react adequately and to adjust own strategies to the opponent. Furthermore, the ability to apply variable patterns of play seems to be promising since they make it harder for the opponent to adjust. The purpose of this study is to identify different team tactical patterns in volleyball and to analyze differences in variability. Overall 120 s…
Kinanthropometric Assessment of Individual, Collective and Fight Sport Players from the Spanish National Sport Technification Program
2020
Nowadays, the study of kinanthropometric parameters is an important tool for both early talent selection and for evaluating the efficacy of a training program. This study aimed to determine the anthropometric characteristics, body composition indicators and somatotype components of individual (athletics, swimming and triathlon), collective (handball and volleyball) and fight (karate and taekwondo) sportsmen and sportswomen from the Valencian Sports Technification Centre. This study involved a total of 62 men and 56 women, they were divided in three subgroups, including individual (athletics, swimming and triathlon), collective (handball and volleyball) and fight (karate and taekwondo) sport…
Effects of a Postural Exercise Program on Vertical Jump Height in Young Female Volleyball Players with Knee Valgus
2022
Background: Although a knee valgus position is related to the increase in injury risk in volleyball players, there is a lack of studies on the relationship between knee valgus and vertical jump (VJ) performance. Hence, the aim of this study was to investigate the effects of a postural exercise program on VJ height in young female volleyball players with knee valgus. Methods: This pilot study included 19 young female volleyball players divided into the following groups: the Valgus Experimental Group (VEG); the Valgus Control Group (VCG); and the Neutral Control Group (NCG). All three groups carried out the same volleyball training program. In addition, only the VEG underwent a 3-month postur…
Values and attributes of volleyball by the fans in the FIVB Men's World Championships 2014
2015
As the world of sport is encountering challenges, such as intensified competition, fragmented markets and loss of commitment, there is a need to discover new insights of the global sport consumers to gain more understanding of their behavior. Volleyball world is not an exception as regards the challenges. Despite its popularity, however, volleyball has not been researched as widely as for example football. The purpose of this master’s thesis was to investigate the image of volleyball through the perceived attributes the spectating fans link to this discipline in the context of an international tournament. Namely fans are the consumers in sport world and work as co-creators of sport events. …
Influence of a sport-specific training background on vertical jumping and throwing performance in young female basketball and volleyball players
2014
Aim. The purpose of this study was to evaluate the influence of 3 years of sport-specific training background (SSTB) on vertical jumping and throwing performance in young female basketball and volleyball players. Methods. Thirty-one healthy adolescent girls, of which 11 age-matched control subjects [C], 10 basketballers (BP) and 10 volleyballers (VP) participated to the study. The throwing performance was assessed by seated backward overhead ball throw (SBOMBT) and seated chest pass throw (SCPT) using a 3-kg rubber medicine ball. Instead, the vertical jumping performance was evaluated by squat jump (SJ) and countermovement jump with (CMJ-AS) and without arm swing (CMJ) using Optojump system…
