Knee peak torque (PT) is associated to jump performance in volleyball players. It not clear whether muscle strength imbalances of the knee joint can influence performance. The purpose study was analyse association between PT and muscular with professional Eleven elite male players (90.3 ± 9.7 kg body mass 1.94 0.06 m height) were evaluated an isokinetic dynamometer at speeds 60, 180 300 deg/s. Muscle obtained through calculation contralateral deficit limbs conventional ratio...

Our aim was to analyze the effect of mental fatigue caused by prolonged social media use on high-level volleyball players' visuomotor skills. Eighteen male young players participated in this randomized, counterbalanced, crossover design. All participants underwent a 2-week experiment which we measured their response times when performing task with and without inducement through repeated immediately before training sessions. In control condition, watched TV for 30-minutes, they used app...

The objective of this study was to evaluate the effects a training session with and without an intervention postactivation performance enhancement (PAPE) on countermovement jump (CMJ) height, perceived recovery status (PRS), ratings exertion (RPEs), followed by specific volleyball session. sample consisted sixteen professional male players, average age 26.8±6.1 years height 195.9±6.7 cm, randomly divided into group PAPE (GPAPE) (n=8), control (CTRL) (n=8). carried out plyometric exercises,...

The authors aimed to compare the effects of 4 weeks jump versus complex training methods on lower limb muscle power and maximal isokinetic torque knee extensors flexors in elite male volleyball players.Sixteen players were allocated into 2 groups, (n = 8; 27.0 [5.7] y, 94.3 [7.6] kg) (with induction postactivation performance enhancement, n 26.6 [3.6] 94.2 [6.3] kg). All individuals performed sessions/wk, group received with enhancement training.After weeks, an increase countermovement...

RESUMOOs testes de saltos e as avaliações no dinamômetro isocinético são amplamente utilizados esporte para a identificação dos parâmetros desenvolvimento força potência.A compreensão da relação entre essas variáveis pode auxiliar nas escolhas mais específicos na avaliação músculos articulação do joelho os jogadores voleibol.O objetivo presente revisão literatura foi reunir estudos que analisaram relações o desempenho com capacidade geração em dinamometria isocinética

This study aimed to quantify internal training load and changes in vertical jumping ability endurance capacity of professional volleyball players during the preseason, explore relationships between players' physical qualities at beginning preseason with accumulated first two weeks training.Sixteen male from a team participating Brazilian National Super League took part study. Before after 10-week their were assessed by squat jump, countermovement jump without arm swing, YoYo test, level 1....

Volleyball is a complex intermittent sport characterized by short explosive technical movements, many of which involve vertical jumping. The assessment mechanical jumping variables in relation to both injury prevention and performance enhancement through the use wearable technologies becoming new training tool among professional volleyball players.The present study aimed assess mechanics before after controlled load (volume intensity) routine session male players. Twelve elite players...

The objective of this study was to identify parameters that best discriminate between selected and non-selected players for the Brazilian under-19 men's volleyball team propose mathematical models high-performance players. To end, 18 (16.89±0.96 years) 138 (16.91±0.74 were assessed training profile, anthropometric physical performance level. discriminant function analysis used build models, with a significance α<0.05. spike jump reach showed greater correlation scores obtained in two...

Vertical jump is an important skill that influences volleyball performance. In this study, we analyzed the relationship between vertical performance and birth quartile of Brazilian male youth players. We calculated chi-square goodness-of-fit tests to compare athletes’ birthdate distributions in quarters their years (Q1, Q2, Q3, Q4) according player age categories (U17, U18, U19, U21). one-way ANOVAs spike block heights players born different same year. Overall, found a relative effect (i.e.,...

The home advantage is very consolidated in the literature. aim of this research was to evaluate behavior heart rate variability (HRV), perceived recovery status (PRS) and rating exertion (RPE) vertical jumps performance professional volleyball athletes away matches. Nine male (25,66 ± 5,7 anos, 97,81 8,65 Kg 200,94 5,19 cm), with experience national international competitions participated study. HRV PRS were evaluated morning RPE collected immediately after Jump monitored during data grouped...

To verify the effect of repeated use social media on smartphones immediately before countermovement jump (CMJ) and internal training load (ITL) sessions in young male high-level volleyball athletes. 18 international-level athletes participated a randomized crossover study for total two weeks. The are from Brazilian under-19 team were into experimental conditions, (SMA) control (CON). SMA used 30 minutes week, while CON watched emotionally neutral videos. During this period, ITL was analyzed...

We aimed to analyse the relationship of peak torque (PT) knee extensors (Ext) and flexors (Fle) with age, between conventional ratio age progression in volleyball players. A total 41 elite male players (age: 25.0 ± 6.1 years, body mass: 93.0 9.8 kg, height: 198.0 6.8 cm) were evaluated a isokinetic dynamometer at speeds 60, 180 300 deg/s, dominant (D) non-dominant (ND) legs. In general, flexor extensor muscles varied greatly among athletes (from 81 156 N.m for flexors; from 116 250 deg/s...

The aim of this research was to evaluate the behavior vertical jumps performance in professional volleyball athletes during matches and training their relationships with fatigue recovery through heart rate variability (HRV), ratings perceived exertion (RPE) status (PRS). Nine male participated study, mean age: 25.66 ± 5.7 years, body mass: 97.81 8.65 Kg height: 200.94 5.19 cm, experience national international competitions. HRV PRS were evaluated morning presentation for first day after...

The evolution of its rules has made the demands different court in-game role more specific in terms skills. However, it is unclear whether players U19 men's volleyball already have specifics according to their role. Thus, aim this study was compare training profiles, anthropometric and physical performance profiles male aged under 19 at 353 (16.89 ± 0.76 years) were evaluated prior Brazilian state team championship games. using a questionnaire; profile obtained by analyzing body mass,...
