The aim of this study was to evaluate the influence of 16 weeks of periodized resistance training (pre-season) on vertical leap measurements and performance in a test specific to volleyball (TW20meters). This study investigated 13 volleyball players participating in statelevel competitions. Vertical leap and TW20meters assessments were performed before (baseline) and after the fifth, ninth, thirteenth, and the sixteenth weeks of physical training. Progressive improvement (P < 0.001) was observed throughout the pre-season compared to baseline values for both tests. In conclusion, periodized resistance training was effective in promoting improvements in vertical leap performance and in a test specifically for volleyball. These data indicate that TW20meters is a test that can be used to detect changes in physical performance induced by resistance training in athletes playing volleyball.

The objective of this study was to evaluate the effects of a training session with and without an intervention of postactivation performance enhancement (PAPE) on countermovement jump (CMJ) height, perceived recovery status (PRS), and ratings of perceived exertion (RPEs), followed by a specific volleyball training session. The sample consisted of sixteen professional male volleyball players, with an average age of 26.8±6.1 years and average height of 195.9±6.7 cm, randomly divided into a group with PAPE intervention (GPAPE) (n=8), and a control group (CTRL) without PAPE intervention (n=8). The control group carried out the training session with plyometric exercises, and the GPAPE added conditioning protocols for PAPE to plyometric training, followed by a technical tactical volleyball session. At the end of the training session, there was an increase of 16.3% in the height of the CMJ in the GPAPE, while the CTRL showed a decrease of 5% in the height of the CMJ. PRS and RPE variables ...

The purpose of this investigation was to examine changes in countermovement vertical jump performance after a single sport-specific training session in a sample of collegiate female volleyball athletes. Eleven NCAA Division I volleyball athletes performed countermovement vertical jumps with and without an arm swing prior to and immediately after a sport-specific training session. Each participant completed two jumps in each condition using a portable force platform. Paired samples t-tests were performed within each jump condition. When using an arm swing, mean braking force was the only variable to display a statistically significant change (p < 0.05). In the no-arm-swing condition, mean propulsive force, propulsive net impulse, jump height and reactive strength index modified all statistically increased (p < 0.05). Time to takeoff was statistically reduced (p < 0.05). Additionally, a single-subject analysis was performed across all eleven participants resulting in general ...

INTRODUCTION -The Purpose of this study was to: a) identify the strength and/or speed variables that determine jumping ability and b) evaluate the effectiveness of a training program attempting to modify these variables. METHODS-Sixteen highly ski lied female volleyball athletes, equally divided into control and experimental groups, were tested tor: a) maximum knee joint extension isometric strength (F.....' knee and hip joints at 90°), b) counter-movement vertical jump with (CMJ1) and without (CMJ2) the use of the arms, c) vertical jump from a flexed (hip, knee and ankle joint) position (SJ), without counter-movement, and d) drop vertical jump (OJ), dropping fram a height of 40cm. Regression analysis revealed that the best predictors (p<O.01) for CMJ1 were: a) the propulsive time in SJ, b) the ratio between propulsive time and flight time in CMJ2, e) F.... during the first 60msec, and d) time to F1IlOJI' Subsequently, the experimental group participated in an 8 week trai...
Twelve-Month Training-Induced Changes in Elite International Volleyball Players
Journal of Strength and Conditioning Research, 2009
Sheppard, JM, Chapman, DW, Gough, C, McGuigan MR, and Newton, RU. Twelve-month training-induced changes in elite international volleyball players. J Strength Cond Res 23 : 2096-2101, 2009-The purpose of this investigation was to examine the strength, power, and anthropometric contributors to vertical jump performances that are considered specific to volleyball success, including countermovement vertical jump (CMVJ) and spike jump (SPJ), by examining changes across 12 months in elite volleyball players. Anthropometry (height, mass, +7 skinfolds), vertical jump ability (CMVJ, SPJ, and depth jumps from 35 cm), kinetic and kinematic data from an unloaded and loaded (body mass + 50%) jump squat were assessed before and after 12 months of training in 20 elite male volleyball players. To examine the association between the change in each of the strength, power, and anthropometric variables with the changes in CMVJ and SPJ, a correlation analysis of the percent change of each variable with the percent change in CMVJ and SPJ was performed. A significant correlation (r = 0.47; p = 0.04) was observed between changes in CMVJ and SPJ. Significant (p = 0.006-0.02) improvements in CMVJ were associated with increased peak force in the unloaded (r = 0.61) and loaded jump squat (r = 0.59) and greater relative power and peak velocity in the loaded jump squat (r = 0.49 and 0.51, respectively). The significant increase in CMVJ was strongly associated (r = 0.865; p , 0.001) with an improved depth-jump ability. Significant (p = 0.003-0.03) increases in SPJ were related to increases in relative power (r = 0.64), peak force (r = 0.46), and peak velocity (r = 0.49) in the loaded jump and improved depth-jumping ability (r = 0.591). This study demonstrates that, in an elite population of volleyball players, stretch-shortening cycle performance and the ability to tolerate high stretch loads, as in the depth jump, are critical to improving jumping performance.

Although velocity control in resistance training is widely studied, its utilization in eliciting post-activation performance enhancement (PAPE) responses receives little attention. Therefore, this study aimed to evaluate the effectiveness of heavy-loaded barbell squats (BS) with velocity loss control conditioning activity (CA) on PAPE in subsequent countermovement jump (CMJ) performance. Sixteen resistance-trained female volleyball players participated in this study (age: 24 ± 5 yrs.; body mass: 63.5 ± 5.2 kg; height: 170 ± 6 cm; relative BS one-repetition maximum (1RM): 1.45 ± 0.19 kg/body mass). Each participant performed two different conditions: a set of the BS at 80% 1 RM with repetitions performed until a mean velocity loss of 10% as the CA or a control condition without CA (CNTRL). To assess changes in jump height (JH) and relative mean power output (MP), the CMJ was performed 5 min before and throughout the 10 min after the CA. The two-way analysis of variance with repeated ...

The purpose of this study was to evaluate the training effects of using accentuated eccentric load counter-movement jumps on lower-body power characteristics in high-performance volleyball players. Sixteen volleyball players training full time with the state high-performance team participated in this 5 week training study. Prior to and at the completion of the study, jump squat testing with a lightweight (350 g) bar was conducted to determine kinetic and kinematic values for the lower body. Players were divided into either the accentuated eccentric load counter-movement jump group (AEJ) or normal (body-mass) counter-movement jump group (BMJ).
Vertical Jump Assessment on Volleyball: A Follow-Up of Three Seasons of a High-Level Volleyball Team
Journal of Strength and Conditioning Research, 2011
Borrà s, X, Balius, X, Drobnic, F, and Galilea, P. Vertical jump assessment on volleyball: A follow-up of three seasons of a high-level volleyball team. J Strength Cond Res 25 : 1686-1694, 2011-This is a longitudinal descriptive study whose purpose is to assess the physical state of male volleyball players competing at the international level, comparing their jump heights during 3 different seasons. National team sample relies upon trainer decisions, and it was different every season. There were 23, 15, and 13 players in the first, second, and third years, respectively. Subjects underwent a vertical test protocol consisting of rocket jump, squat jump (SJ), countermovement jump (CMJ), CMJ with arms (CMJa), and spike jump (DJb) at the preparation period of the national team season. In 2007, an extra evaluation was performed during the competitive period. A contact mat was used for the assessment. An increase of jump height was observed over the years, with SJ and DJb increasing significantly (F SJ = 5.4; F DJb = 4.7; p , 0.05). The elasticity index decreased significantly between 2007 and 2008 (F EI = 8.5; p , 0.05), whereas arm utilization index and approach index increased, but this increase was not statistically significant. A significant increase in SJ and DJb was also observed between the 2 tests performed in 2007, whereas a nonsignificant increase was observed for CMJ and CMJa. The results indicate a better performance of explosive strength, elastic-explosive strength, and reflex-elastic-explosive strength and a better use of arms during jumps.

The purpose of this investigation was to examine the potential strength, power, and anthropometric contributors to vertical jump performances that are considered specific to volleyball success: the spike jump (SPJ) and counter-movement vertical jump (CMVJ). To assess the relationship among strength, power, and anthropometric variables with CMVJ and SPJ, a correlation and regression analysis was performed. In addition, a comparison of strength, power, and anthropometric differences between the seven best subjects and the seven worst athletes on the CMVJ test and SPJ test was performed. When expressed as body mass relative measures, moderate correlations (0.53-0.65; p # 0.01) were observed between the 1RM measures and both relative CMVJ and relative SPJ. Very strong correlations were observed between relative (absolute heightstanding reach height) depth jump performance and relative SPJ (0.85; p # 0.01) and relative CMVJ (0.93; p # 0.01). The single best regression model component for relative CMVJ was the relative depth jump performance, explaining 84% of performance. The single best predictor for relative SPJ was also the relative depth jump performance (72% of performance), with the three-component models of relative depth jump, relative CMVJ, spike jump contribution (percent difference between SPJ and CMVJ), and relative CMVJ, spike jump contribution, and peak force, accounting for 96% and 97%, respectively. The results of this study clearly demonstrate that in an elite population of volleyball players, stretch-shortening cycle performance and the ability to tolerate high stretch loads, as in the depth jump, is critical to performance in the jumps associated with volleyball performance.
