There is an evident lack of studies on the effectiveness of plyometric- and skill-based-conditioning in volleyball. This study aimed to evaluate effects of week plyometric- and volleyball -skill-based training on specific conditioning abilities in female volleyball players. The sample included 41 high-level female volleyball players Both programs were performed twice per week. All tests were assessed at the study baseline pre- and at the end of the week programs post-testing.
Future studies should evaluate differential program effects in less experienced and younger players. Volleyball damping corresponds to linear damping up to a certain critical velocity, with zero damping above this value. The dynamics of a linear harmonic oscillator is investigated with this damping mechanism.
Background: There is a relative paucity of research examining the sport-specific injury epidemiology of high school and collegiate volleyball athletes. Hypothesis: There are differences between the injury patterns characteristic of high school and collegiate female volleyball athletes. Study Design: Retrospective clinical review. Level of Evidence: Level 3. Results: The overall volleyball -related injury rate was significantly greater among collegiate athletes than among high school athletes during both competition injury rate ratio, 2.
Conclusion: The data suggest that although similar, there were distinct differences between the injury patterns of the 2 populations.
Clinical Relevance: The injury data suggest that important. Effect of simulation training on compliance with difficult airway management algorithms, technical ability , and skills retention for emergency cricothyrotomy. The effectiveness of simulation is rarely evaluated. The aim of this study was to assess the impact of a short training course on the ability of anesthesiology residents to comply with current difficult airway management guidelines.
Twenty-seven third-year anesthesiology residents were assessed on a simulator in a "can't intubate, can't ventilate" scenario before the training the pretest and then randomly 3, 6, or 12 months after training the posttest. The scenario was built so that the resident was prompted to perform a cricothyrotomy. Compliance with airway management guidelines and the cricothyrotomy's duration and technical quality were assessed as a checklist score [0 to 10] and a global rating scale [7 to 35].
The main aim of this study was to compare the training load TL executed by volleyball players with that observed by coaches. Second, we analyzed the influence of the coaches' experience in the estimated TL. Twelve female volleyball players and 4 male coaches participated in this study. During a period of 15 weeks, physical PT and technical -tactical training sessions and matches were monitored. Both players' and coaches' mean sRPE 4. However, a higher p volleyball. Changes in skill and physical fitness following training in talent-identified volleyball players. This study investigated the effect of a skill-based training program on measurements of skill and physical fitness in talent-identified volleyball players.
Skills sessions were designed to develop passing, setting, serving, spiking, and blocking technique and accuracy as well as game tactics and positioning skills. Coaches used a combination of technical and instructional coaching, coupled with skill-based games to facilitate learning. Subjects performed measurements of skill passing, setting, serving, and spiking technique and accuracy , standard anthropometry height, standing-reach height, body mass, and sum of 7 skinfolds , lower-body muscular power vertical jump, spike jump , upper-body muscular power overhead medicine-ball throw , speed 5- and m sprint , agility T-test , and maximal aerobic power multistage fitness test before and after training.
Training induced significant p volleyball training improves spiking, setting, and passing accuracy and spiking and passing technique, but has little effect on the physiological and anthropometric characteristics of players. Bridging the Gap in Volleyball. From Basic Instruction to Game Play. Using volleyball "mini games," which emphasize, one at a time, skills needed to play volleyball , helps students to develop skills needed to play.
Mini games described are: 1 forearm pass; 2 overhand pass; 3 overhand pass; 4 overhand serve; 5 mini volleyball ; and 6 alternate court set-up. Key points Plyometric- and skill-based-conditioning resulted in improvements in jumping and throwing capacities, but plyometric training additionally induced positive changes in anthropometrics and sprint. Prospective study of injury in volleyball players: 6 year results. The volleyball game has a high complexity and thus entails a lot of strain to the players. Due to this high and different training and competition strain comprehensive and individual training plans should be developed with competing training objectives in order to prevent injuries.
The aim of the study was to analyse prospectively over six seasons the acute and overuse injuries of a German male professional volleyball team. All players received a sport medicine examination and a functional diagnosis before each season. Based on the results the players received an individual training plan. The players suffered injuries. The prevalence of acute injuries was 1. The incidence of acute injuries was 3. The largest number of injuries was found in the spine. The players had most likely minor injuries.
The players had significantly fewer injuries in their second season 1. It could be concluded that volleyball is a sport with a relative low prevalence of injuries compared to other team sports. The prevalence of injury is 2. Due to an injury a player dropped out An individual training program seems to reduce the incidence of injury. Experiences of returning to elite beach volleyball after shoulder injury. The purpose of this study was to examine beach volleyball players' experience regarding shoulder injury and how it affects their return to play.
To achieve the research aims a qualitative design with semi-structured interviews had been conducted, five elite beach volleyball players, four men and one woman aged participated in the study. All participants had suffered a severe shoulder injury, with absence from training and competing for at least 28 days. The findings of this study indicate that it is the individual's inner motivation, together with a clear goal and support from the community, family, teammate and coach that are the most important factors when going through rehabilitation and getting back to playing beach volleyball after a shoulder injury.
All participants had been affected by their injury in some way; some of the participants had been affected in a positive way since they had become mentally stronger and had developed better volleyball technique after rehabilitation. The conclusions of this study indicate that there are three distinct factors that increase the chances of getting back to playing beach volleyball after shoulder injury; it is the players' self motivation, together with a clear goal and support from the community.
To achieve the research aims a qualitative design with semi-structured interviews had been conducted, five elite beach volleyball players, four men and one woman aged 27—42 participated in the study. The volleyball athlete's shoulder: biomechanical adaptations and injury associations. In volleyball , the dominant shoulder of the athlete undergoes biomechanical and morphological adaptations; however, definitive conclusions about their exact nature, aetiology, purpose and associations with shoulder injury have not been reached. The reviewed literature supports the existence of a glenohumeral internal rotation deficit GIRD and a possible and less pronounced external rotation gain in the dominant vs.
Additionally, the dominant shoulder exhibits muscular imbalance, which appears to be a significant risk factor for shoulder pain. Strengthening of the external rotators should be used alongside shoulder stretching and joint mobilisations, core strengthening and optimisation of spike technique as part of injury management and prevention programmes. Validation of the VERT wearable jump monitor device in elite youth volleyball players. Borges, Thiago O. The participants of this study were all experienced volleyball players from the U18 category from the Brazilian National team.
Each athlete performed 3 attack and 3 block jumps in a random, counterbalanced order, and the average score was registered. The VERT device was found to be a very practical tool to quantify jump performance in volleyball players. Somatotype, size and body composition of competitive female volleyball players.
The aim of this study was to describe the morphological characteristics of competitive female volleyball players. For this purpose, body weight and height, breadths and girths as well as skinfold thickness at various body sites were assessed in elite female volleyball players age: Seventy-nine of these players were from the A1 division and the rest from the A2 division of the Greek National League. Two-way ANOVA was used to compare the differences in these characteristics between competition level and playing position. Body height ranged from cm to cm, and the mean value Adiposity of these players sum of 5 skinfolds: Volleyball athletes of this study were mainly balanced endomorphs 3.
The A1 division players were taller and slightly leaner with greater fat-free mass than their A2 counterparts. Significant differences were found among athletes of different playing positions which are interpreted by their varying roles and physical demands during a volleyball game. The volleyball players who play as opposites were the only subgroup of players differing between divisions; the A2 opposites had more body fat than A1 opposites. These data could be added in the international literature related to the anthropometric characteristics of competitive female volleyball players.
Training strategy of explosive strength in young female volleyball players. The aim of this study was to examine the effect of an 8-week combined jump and ball throwing training program in the performance of upper and lower extremities among young female volleyball players of the high school.
The experimental group received additional plyometric and ball throwing exercises besides their normal volleyball practice. The control group underwent only their regular session of training. The 8-week combined jump and ball throwing training can significantly improve muscular performance in young female volleyball players. These findings may be useful for all physical education teachers and volleyball coaches. The relative contribution of motivation to ability measures in predicting performance criteria of sales personnel from successive fiscal periods was investigated.
In this context, the merits of a multiplicative and additive combination of motivation and ability measures were examined. The relationship between satisfaction and motivation and…. Anthropometric and performance measures to study talent detection in youth volleyball. The aim of this work was to study anthropometric and performance measurements in 60 young male volleyball players YV and 60 youth not active in the sport YNA to assess which of these would be more useful to study the characteristics of potential performers.
Eight measures to assess anthropometric characteristics, six performance measures and two tests for joint mobility were used. Also relative age and level of maturation were assessed. The anthropometric variables, relative age and level of maturation measured did not show statistically significant differences between groups. YV group was characterized by a better performance of the ability to repeat short sprints, of the upper limbs, abdominal muscles and lower limbs, with a medium effect size Shuttle Running Test: 0.
These performance variables were very sensitive and specific: the SRT measurement had the best positive likelihood ratio that indicates the utility of the test in identifying type of players YV and YNA. In talent detection in youth volleyball , in the age range, performance variables should be preferred to anthropometric ones.

This article shares teaching strategies for the forearm pass in the game of volleyball and identifies how they will help students improve their performance and development of forearm passing skills.
The article also provides an assessment rubric to facilitate student understanding of the skill. Collective efficacy can be defined as a group's shared confidence that they will successfully achieve their goal. We examined which behaviours and events are perceived as sources of collective efficacy beliefs in a volleyball context. This list was then adapted based on the literature and on feedback given by an expert focus group, resulting in a item questionnaire. A principal component analysis revealed that the 40 sources could be divided into eight internally consistent factors.
Positive supportive communication e. The factor referring to the negative emotional reactions of players e. These findings offer a starting point for the design of continuous measurements of collective efficacy through observation. Effectiveness of the call in beach volleyball attacking play. In beach volleyball the setter has the opportunity to give her or his hitter a "call". The call intends that the setter suggests to her or his partner where to place the attack in the opponent's court.
The effectiveness of a call is still unknown. We investigated the women's and men's Swiss National Beach Volleyball Championships in and analyzed attacks. We found large differences between female and male players. While men called in only The success rate of attacks without any call was In women's beach volleyball , the rate of successful attacks was Considering the quality of calls we indicate that there is a significant potential to increase the effectiveness of a call. Kinanthropometric profile of Cuban women Olympic volleyball champions.
Athletes' kinanthropometric profiles are widely addressed in the scientific literature. Such profiles are particularly important in volleyball because absolute size contributes a significant percentage of total variance associated with athletic success. As in other team sports, volleyball players' kinanthropometric attributes correlate with the game's tactical demands. From through , the Cuban women's volleyball team achieved top global performance, winning first place in three successive Summer Olympic Games.
Describe the kinanthropometric profiles of Cuban women Olympic volleyball champions during and compare these by position played. Measurements were taken of body composition, somatotype, proportionality and several anthropometric indicators in 41 Cuban women volleyball players, grouped by playing position. All were members of the national team that participated in the Summer Olympic Games in Barcelona , Atlanta and Sydney Mean and standard deviations were calculated for all study variables.

Discriminant analysis was performed to identify anthropometric dimensions differentiating playing positions center, spiker and setter , using p volleyball players was balanced mesomorphic 2. Classified by position, centers 2. On assessing Somatotype Attitudinal Mean SAM , centers and spikers showed more intrapositional homogeneity than that of setters. Centers were significantly.
The aim of this study was to examine the effect of volleyball and basketball practice on bone acquisition and to determine which of these 2 high-impact sports is more osteogenic in prepubertal period. We investigated boys aged yr, Tanner stage I : 50 volleyball players VB , 50 basketball players BB , and 70 controls. Bone mineral content BMC, g and bone area BA, cm 2 were measured by dual-energy X-ray absorptiometry at different sites. No significant differences were observed between the 3 groups in lumbar spine, femoral neck, and left third D radius BMC.
Athletes also exhibited a higher BA in whole body, limbs, lumbar spine, and femoral region than controls. In addition, they have a similar BA in head and left third D radius with controls. A significant positive correlation was reported between total lean mass and both BMC and BA in whole body, lumbar spine, total hip, and right whole radius among VB and BB. In summary, we suggest that volleyball and basketball have an osteogenic effect BMC and BA in loaded sites in prepubescent boys.
The increased bone mass induced by both volleyball and basketball training in the stressed sites was associated to a decreased skull BMC. Moreover, volleyball practice produces a more sensitive mechanical stress in loaded bones than basketball. This effect seems translated by femoral neck expansion. Published by Elsevier Inc.

Moving from technical to critical reflection in journalling: an investigation of students' ability to incorporate three levels of reflective writing. This paper outlines a research project aimed at changing the levels of reflection of preregistration nursing students in a tertiary institution. Whilst reflection is widely espoused now in nursing, few studies have been found that identify whether the level of reflective writing can be identified or developed by students.
Anecdotal and research evidence Powell ; van Manen however indicates that most student reflective writing occurs at the technical level. A descriptive exploratory study using both qualitative and quantitative techniques was undertaken to apply van Manen's levels in a structured way in an attempt to facilitate the student's understanding and use of the levels in their reflective writing.
The findings of the study indicate that student self evaluation and identification of the levels in their own writing can lead to change in the levels of critical reflective writing achieved by undergraduate students. Caffeinated energy drinks improve volleyball performance in elite female players. The objective of this study is to determine the effects of a caffeine-containing energy drink on female volleyball players' performance. Then, participants performed the following: standing spike, jumping spike, spike jump, blocking jump, squat jump, countermovement jump, manual dynamometry, and the agility t-test.
A simulated volleyball game was played, videotaped, and notated afterward. In comparison to the placebo drink, the ingestion of the caffeinated energy drink increased the ball velocity in the standing spike Furthermore, the caffeinated energy drink decreased the time needed to complete the agility t-test Increased physical performance led to improved accuracy during an actual volleyball match.

Physical performance and positional differences among young female volleyball players. The purpose of this study was to investigate the association among anthropometric, physical performance parameters, and dynamic postural control attributes of young female volleyball athletes, and to determine if differences exist in these attributes according to playing position.
Forty-three young female volleyball players participated in this study. Players were divided by position into hitters N. No difference was observed between groups for reach distance scores in the SEBT. These results demonstrate important positional differences in agility measures of young female volleyball players.
Coaches can use this information to determine the type of physical profile that is needed for specific positions and to design training programs to maximize strength, power, and neuromuscular development of young female volleyball athletes. The aim of this study was to characterize the cardiovascular and musculoskeletal systems of elite volleyball players, including aortic dimensions. Previous studies have shown that the upper limit of normal aortic sinus diameter for male and female athletes is 4 and 3. Cross-sectional analysis. Seventy 37 male members of the US national volleyball team. Athletes underwent evaluation that included medical and family histories, targeted physical examinations specifically focusing on abnormalities present in Marfan syndrome MFS , and transthoracic echocardiograms.
Cardiac chamber and great artery size, valve function, and coronary artery origins were assessed. There were no other intracardiac or arterial abnormalities. Individual musculoskeletal characteristics of MFS were common among the athletes but not more frequent or numerous in those with aortic dilation. The prevalence of aortic root dilation in this population of athletes was higher than what has previously been reported in other similar populations. Further study is needed to determine whether these represent pathological changes or normal variations in tall athletes.
This study adds to the existing knowledge base of athlete's heart, with specific attention to aortic dimensions in elite volleyball players. The data are relevant to similar athletes' medical care and to preparticipation cardiac screening in general. Isokinetic testing of the shoulder joint shows valuable indication to possible functional disorders and muscle imbalance.

Significant P volleyball players. Y-balance normative data for female collegiate volleyball players. The Lower Quarter Y Balance YBT-LQ Test performance varies depending on competitive level, sport, gender, and age; therefore, determining normative scores specific to a population may be helpful in identifying injury-risk thresholds and return-to-play criteria following an injury. A descriptive analysis cohort study. Ninety healthy Baseline values for this population were This study identified normative YBT-LQ composite scores for healthy, female, collegiate volleyball players.
Participants performed similarly despite their position. Thus, an early diagnosis of MetS is needed in this population to improve the prevention of cardiovascular disease and type 2 diabetes in adulthood. Most of these professionals Additionally, it was observed that However, They do not conduct a deliberate search for MetS risk factors, which is a major limitation for diagnosis and early treatment.
Therefore, we suggest a systematic approach for maintaining the standards of health professionals and to make determining the criteria for proper diagnosis of MetS a target of clinical practice. The purpose of this study was to examine a hybrid combination of sport education and the step-game-approach SGA on students' gameplay performance in volleyball , taking into account their sex and skill-level. Seventeen seventh-grade students seven girls, 10 boys, average age This research is conducted to determine the physical profiles of sitting volleyball players of the Turkish National Team.
The anthropometric measurements were taken over dominant extremity. In order to determine the physical features of the…. Previous studies utilizing jump-landing biomechanics to predict anterior cruciate ligament injuries have shown inconsistent findings. The purpose of this study was to quantify the differences and correlations in jump-landing kinematics between a drop-jump, a controlled volleyball -takeoff, and a simulated-game volleyball -takeoff. Seventeen female volleyball players performed these three tasks on a volleyball court while three-dimensional kinematic data were collected by three calibrated camcorders.
Participants demonstrated significantly increased jump height, shorter stance time, increased time differences in initial contact between two feet, increased knee and hip flexion at initial contact and decreased peak knee and hip flexion for both left and right legs, and decreased knee-ankle distance ratio at the lowest height of mid-hip for the two volleyball -takeoffs compared with the drop-jump p volleyball -takeoffs p volleyball -takeoffs.
Controlled drop-jump kinematics may not represent jump-landing kinematics exhibited during volleyball competition. Jump-landing mechanics during sports-specific tasks may better represent those exhibited during sports competition and their associated risk of ACL injury compared with the drop-jump.

Blood glucose BG was assessed prior to supplementation and immediately after set three. The supplement and PBO were administered prior to play and between sets two and three. As these performance tests were largely anaerobic and non-glycolytic in nature, the ergogenicity of the supplement may have been underutilized.
Additionally, coaches and athletes should not only be aware of what ingredients are in the supplements they choose, but the amount of those ingredients as they may modify the efficacy of the supplement to impact performance. Vortex-induced dynamic loads on a non-spinning volleyball. An experiment on vortex-induced dynamic loads on a non-spinning Volleyball was conducted in a wind tunnel. The flow past the Volleyball was visualized, and the aerodynamic load was measured by use of a strain gauge balance.
The separation on the Volleyball was measured with hot-film. The experimental results suggest that under the action of an unstable tail vortex system the separation region is changeable, and that the fluctuation of drag and lateral forces is the same order of magnitude as the mean drag, no matter whether the seam of the Volleyball is symmetric or asymmetric, with regard to the flow. Based on the experimental data a numerical simulation of Volleyball swerve motion was made.
