“…In the study of Smith et al (7) , volleyball athletes were divided into strength-training group and control group. The strengthtraining group increased significantly the vertical jump and the knee extension at 180º.s -1 , while the control group did not obtain significant increase, otherwise decreasing the power of the block jump.…”

“…Also for children and youth, this component has been emphasized, reflecting the large number of studies on the trainability of strength in children (1) . The muscular strength is important in many sports (2)(3)(4)(5) and, specifically in volleyball, it is widely used (2,(5)(6)(7) . Volleyball is a sportive modality that requires power in the upper members (especially shoulders), lower members (jumps) and trunk, besides aerobic conditioning in order to stay in a game that could last for as long as three hours (8) .…”

O objetivo deste estudo foi descrever e comparar as forças musculares isométrica e isocinética em diferentes graus maturacionais de meninos e meninas atletas de voleibol. Participou do estudo um total de 66 crianças e adolescentes saudáveis, em treinamento esportivo competitivo. Dos 37 meninos, 10 eram pré-púberes (PP), 15 púberes (PU) e 12 pós-púberes (PO). Das 29 meninas, 11 eram PP, 13 PU e 5 PO. Foi utilizado um dinamômetro computadorizado (Cybex Norm) para medir a força isocinética de flexão do cotovelo (FC) e de extensão de joelho (EJ) nas velocidades de 60 e 90º.s-1. A força isométrica foi medida nos mesmos exercícios nos ângulos de 60 e 90º (FC), e 45 e 60º (EJ). Utilizou-se a ANOVA para comparações entre os gêneros e graus maturacionais, e o teste post hoc de Tuckey. O nível de significância considerado foi de p < 0,05. Entre os graus maturacionais, os grupos mais velhos foram sempre mais fortes do que os mais jovens, tanto para o gênero masculino quanto para o feminino. Entre os gêneros, os meninos foram mais fortes do que as meninas apenas no grupo PO, nos dois ângulos dos testes isométricos de FC e no teste isocinético em 90º.s-1. Nos testes isométricos de EJ, os valores não foram significativamente diferentes para meninos e meninas, independentemente do grau maturacional. Nos testes isocinéticos, os meninos foram mais fortes do que as meninas nos grupos PP e PO, em 60 e 90º.s-1. Esses resultados sugerem que o grau maturacional é maior determinante da força muscular de jovens atletas de voleibol do que o gênero.

“…The search yielded 24 observational studies: 12 of male (Gladden & Colacino, 1978; Viitasalo, 1982; Lee et al, 1989; Smith et al, 1992; Stockbrugger & Haennel, 2003; Kollias et al, 2004; Forthomme et al, 2005; Hertogh et al, 2005; de Ruiter et al, 2007; Laffaye et al, 2007; Sheppard et al, 2007a, b, 2008), 10 of female (Gladden & Colacino, 1978; Spence et al, 1980; Fleck et al, 1985; Marey et al, 1991; Hakkinen, 1993; Ferris et al, 1995; Barnes et al, 2007; Nesser & Demchak, 2007; Stech & Smulsky, 2007; Amasay, 2008), and two of male and female (Coutts, 1982; Lawson et al, 2006) players. In addition, eight experimental studies were found: four of male (Newton et al, 1999; Maffiuletti et al, 2002; Saez Saez de Villarreal et al, 2007; Pereira et al, 2008) and four of female (Smith et al, 1987; Fry et al, 1991; Newton et al, 2006; Marques et al, 2008) players. A summary of the observational and experimental studies of female and male players is presented in Tables 1 and 2, respectively.…”

The main purpose of this article was to review a series of studies (n=32; 24 observational and eight experimental) examining vertical jump (VJ) performances in female and male volleyball players. The main findings of this review are (a) players of better performing teams have higher VJ values; (b) strength and conditioning programs that emphasize plyometric training can increase VJ performance; and (c) it is important to continue conditioning sessions throughout the season in order to maintain VJ performance. Three research limitations associated with the testing protocols and the strength and conditioning programs used in the studies were outlined: (a) the use of multiple testing protocols; (b) lack of experimental studies; and (c) lack of data on the effect of VJ performance on achieving success in actual games. Four recommendations for volleyball and strength and conditioning coaches were given: (a) Plyometric training should be included in the annual training program; (b) Interruptions in the conditioning program during the season should be avoided; (c) Overtraining during the pre-season should be avoided; and (d) VJ performance should be tested throughout the entire season.

“…Explosive muscle strength is an important performance variable, as are motor properties such as jumping and sprinting. [1][2][3][4] Muscular strength also helps volleyball players avoid overload injuries. The bodily velocities achieved during volleyball games can require great muscular and neural activity.…”

“…A commonly tested motor task is the vertical jump, which is related to leg extensor muscle strength. [1][2][3]5 The vertical jump is the test most frequently used by trainers and researchers to identify lower body muscle strength. 6 The ability to jump vertically is one of the determining variables of volleyball performance.…”

A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The aim of this study was to determine the relationship among maximum isokinetic concentric knee torque, muscle activity (EMG) and vertical jumping height of Turkish elite male volleyball players. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Twelve elite male volleyball players were included voluntary in this study. EMG activity was recorded on the vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF) and biceps femoris (BF) muscles of volleyball players during five maximal isokinetic concentric-concentric contractions at 60°/s, 180°/s and 240°/s. Peak anaerobic power output was calculated using vertical jumping heights. A repeated measures analysis of variance (ANOVA) was used to compare torque values in different angular velocities. Pearson's correlation coefficient was used to evaluate the relationship between torque and muscle activation values. The statistical significance level was set at p<0.05. R Re es su ul lt ts s: : The results of this study show that Hamstring/Quadriceps (H:Q) ratios are greatest at an angular velocity of 240°/s. Differences in EMG activity during isokinetic testing were observed between the knee extensor (VL, VM) and flexor muscles (BF) (p<0.05). Repeated maximal isokinetic concentric contractions caused to increase the EMG activity of the knee and flexor muscles (p<0.05). In this study, it is demonstrated that volleyball players produced significantly higher counter movement jumping (CMJ) heights than squat jumping (SJ) heights (10%) (p=0.028). The maximum power of a CMJ was higher than that of an SJ (p=0.000), concentric work (p=0.001) and peak anaerobic power (p=0.020). Additionally, negative correlation was observed between VM, RF and BF muscle activation and isokinetic concentric-concentric torque values. C Co on nc cl lu us si io on n: : It was thus concluded that the muscle activity of the knee extensor and flexor muscles changes with change in isokinetic torque at different angular velocity and repetition.K Ke ey y W Wo or rd ds s: : Muscle activation; torque; isokinetic force Ö ÖZ ZE ET T A Am ma aç ç: : Çalışmanın amacı Türk elit erkek voleybolcuların diz ekstansör ve fleksör kaslarının maksimum konsantrik tork, dikey sıçrama ve kassal aktivasyon (EMG) değerleri arasındaki ilişkileri belirlemektir. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : On iki elit erkek voleybolcu gönüllü olarak çalışmaya dahil edilmiştir. Voleybolcuların vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF) ve biceps femoris (BF) kaslarının kassal aktiviteleri (EMG), 60°/s, 180°/s and 240°/s açısal hızlarda, 5 maksimal izokinetik konsantrik-konsantrik kasılma sırasında kayıt edilmiştir. Zirve anaerobik güç çıktısı, squat sıçrama (SS) ve aktif sıçrama (AS) verileri hesaplanarak oluşturulmuştur. Farklı açısal hızlarda elde edilen tork değerleri tekrarlayan ölçümlerde varyans analizi (ANOVA) ile karşılaştırılmıştır.
