Optimal Timing for Post-Activation Potentiation in Women Collegiate Volleyball Players.

Post-activation potentiation (PAP) has been shown to acutely amplify muscular power output and may be advantageous for athletes looking to improve performance. PAP may have an acute window of effectiveness between 2 to 20 min. With correct timing and implementation it may be possible to induce PAP in competitive situations. The purpose of this study was to examine the time frame of potentiation following a PAP warm-up in collegiate female volleyball players. In this study, nine female collegiate volleyball players completed three laboratory sessions over the course of 10 days. During the first session, the athlete’s 5-RM back squat was determined for subsequent use as the conditioning activity to initiate PAP. A repeated measures experimental design was then employed for Sessions 2 and 3 where half of the participants alternately performed either a dynamic or PAP warm-up prior to performing a standing long jump (SLJ) at 2, 6, 10, 14, and 18 min. A mixed-factor repeated measures ANOVA was used to determine the effects of the two warm-up strategies (PAP vs. dynamic) on standing long jump (SLJ) performance across time. There was a significant effect for time (p < 0.01) and warm-up strategy (p < 0.01). Bonferroni post hoc techniques determined that the SLJs that followed the PAP warm-up were significantly greater at 2 (4.8%), 6 (3.6%), and 10 (3.6%) min compared to SLJs post-dynamic warm-up (p < 0.05). However, those differences did not persist at 14 or 18 min (p > 0.05). Further analysis included non-parametric pairwise comparisons (Wilcoxon signed-rank tests) between the SLJ scores at 2, 6, 10, 14, and 18 min (PAP vs. dynamic). The non-parametric results were consistent with the parametric results. Within the parameters of this study, it is concluded that performing a 5-RM back squat induces a measureable PAP effect for up to 10 min.

Relationships Between Muscle Architecture And Measures Of Strength And Power In Collegiate Volleyball Players

PURPOSE:To examine the relationships between muscle architecture and countermovement jump height, peak power, and maximal strength in collegiate volleyball players and to generate hypotheses to direct future research. METHODS:Fourteen female volleyball players (20 ± 1.3y, 176.3 ± 6.6cm, 70.1 ± 8.4 kg) were recruited as part of an ongoing athlete monitoring program. Athletes were tested on measures of vastus lateralis (VL) and lateral gastrocnemius (LG) muscle thickness (MT), pennation angle (PA), and fascicle length (FL) using ultrasonography; countermovement jump height (CMJH, n = 14) and peak power allometrically scaled (CMJPPa, n = 14); and isometric peak force allometrically scaled (IPFa, n = 12). Data were screened for outliers using box plots and normality was determined using a Shapiro-Wilk test. Intraclass correlation coefficients (ICCs) for dependent variables ranged from r=0.88 to 0.99. Pearson’s product moment zero-order correlations were used for analysis with critical alpha set to p ≤ 0.05. RESULTS:Analysis revealed a positive relationship between VL MT and IPFa (r = 0.64, p = 0.025) and an inverse relationship between LG MT and CMJH (r = -0.54, p = 0.048). There were positive relationships between VL PA and all performance measures and between LG PA and CMJPPa (r = 0.54 to 0.71, p. < 0.05), and inverse relationships between VL FL and CMJPPa and between LG FL and all performance measures (r = -0.59 to −0.67, p < 0.05). CONCLUSIONS: Better jumpers had larger PA and shorter FL in both VL and LG, and stronger athletes had greater MT in VL, showing that muscle architecture may influence performance variations in volleyball athletes. Considering these findings and the results from previous longitudinal studies demonstrating the effects of heavy strength training on muscle architecture, it is recommended that volleyball athletes incorporate heavy lower body strength training into their training plan in order to increase PA in VL and LG and MT in VL. Based on the relationships found in this study, it is hypothesized that favorable training adaptations in MT and PA will correlate with improved jumping performance and strength in volleyball athletes. Further research should gather longitudinal resistance training, athlete monitoring and testing, and muscle architecture data to explore this hypothesis.

Changes in Muscle Architecture and Explosive Ability in Collegiate Volleyball Players throughout a Competitive Season

PURPOSE: Limited research exists examining muscle architectural changes in conjunction with performance measures throughout an athlete’s competitive season. The purpose was to examine changes in muscle architecture and explosive ability in DI collegiate volleyball players throughout a competitive season. METHODS: Ten female volleyball players (20.4 ± 1.1 y, 178.3 ± 4.8 cm, 72.6 ± 5.3 kg) were recruited for the study. Athletes were tested at pre-season (T1), pre-taper (T2), and post-taper (T3) on measures of vastus lateralis muscle thickness (MT), pennation angle (PA), and fascicle length (FL) using ultrasonography, countermovement jump height (JH), time to takeoff from initiation of the unweighting phase (TTT), and peak power allometrically scaled (PPa) measured using a force platform. Training load (TL: session RPE·duration) and strength training volume-load times displacement (VLd) were monitored for 15 wks. One-way repeated measures ANOVAs with post-hoc comparisons were used for analysis with alpha level set at p≤0.05. RESULTS: There was a reduction in VLd/wk (1886 ± 422 to 571 ±130 kg/wk, p<0.001, d=3.1) and TL/wk (3140 ± 561 to 1656 ± 409 a.u., p<0.001, d=2.7) between in-season (T1-T2) and tapering (T2-T3) training phases. There were time effects for MT (p<0.001) and PA (p=0.03). Post-hoc comparisons revealed changes in MT (T1-T2: 2.1 ± 0.3 to 2.96 ± 0.54 cm, p<0.001, d=2.8; T1-T3: 2.1 ± 0.3 to 2.63 ± 0.36 cm, p<0.001, d=1.7; and T2-T3: 2.96 ± 0.54 to 2.63 ± 0.36 cm, p=0.01, d=0.6), PA (T1-T2: 12.59 ± 0.81 to 15.76 ± 3.38°, p=0.02, d=3.9), and no statistical changes in FL, JH, or PPa. Despite the absence of a time effect, a decreasing trend was observed in TTT from T1-T3: 798 ± 98 to 767 ± 106 ms, p=0.04, d=0.32, and T2-T3: 789 ± 101 to 767 ± 106 ms, p=0.04, d=0.22. CONCLUSION: In-season training resulted in favorable changes in muscle architecture, which remained elevated above pre-season values following the taper. These muscle architectural changes did not appear to appreciably alter explosive ability throughout the competitive season. However, the reductions in TL and VLd during the taper might have improved stretch-shortening cycle efficiency as evidenced by the reductions in TTT. Collegiate volleyball athletes may benefit from a taper where both TL and VLd are substantially reduced prior to important competitions.

Superolateral Hoffa's Fat Pad Edema in Collegiate Volleyball Players.

Superolateral Hoffa's fat pad (SHFP) edema is a previously described magnetic resonance (MR) finding located between the patellar tendon and the lateral femoral condyle. The purpose of our study was to determine the prevalence and clinical significance of SHFP edema in female collegiate volleyball players. Sixteen female collegiate volleyball players were consented for bilateral knee evaluations which consisted of history, physical examination and MR imaging. Each MR study was reviewed for the presence of SHFP edema, and 6 patellar maltracking measurements were done. These were tibial tuberosity-trochlear groove distance, patellar translation, lateral patellofemoral angle, trochlear depth, trochlear sulcus angle, and lateral trochlear inclination angle. A total of 16 athletes, 32 knees (16 girls; age range, 18-22 years; mean, 19.9) were enrolled in the study. Sixteen knees (50%) in 8 athletes had SHFP edema, with 100% bilaterality; 16 knees in 8 athletes had no evidence of SHFP edema (50%). Functional outcomes and physical examination findings were within normal limits for all athletes with no difference noted between SHFP edema-positive and -negative individuals. There was a statistically significant difference in the tibial tuberosity-trochlear groove distance, patellar translation, and patellofemoral angle (P value of < 0.001, 0.03 and 0.01, respectively) between the SHFP edema-positive and -negative individuals. Elite female volleyball athletes have a very high prevalence of SHFP edema, which is always bilateral. Although the exact etiology of SHFP edema remains inconclusive, it could potentially be a sensitive indicator of subtle patellar maltracking which cannot be distinguished by history and physical examination findings. Given the very high prevalence of SHFP edema and this being an asymptomatic finding, there is likely little clinical significance of this in majority of high-performance athletes.

Effects of the Thai massage program on range of motion of lower extremities and vertical jump performance in collegiate volleyball players, Burapha Univeristy, Thailand

Sport massage can enhance athletic physical performance which is similar to Thai traditional massage but no evidence reports the increase in athletic performance before competition. The purpose of this research was to study effects of the Thai massage program on range of motion (ROM) of lower extremities and vertical jump performance (VJP) in collegiate volleyball players. Twelve males and twelve females in collegiate volleyball, age between 18-22 years, were randomly divided into two groups; experimental (N = 12) and control groups (N=12). All subjects were measured ROM including knee flexion, ankle plantarflexion and dorsiflexion, and VJP. Thai massage program was applied to the experimental group for 30 minutes and the control group sat still for 30 minutes. The post-test was done and the tests were repeatedly measured every other day for 3 days. The mean differences of the pre and post-test data were calculated and statistically analyzed by using repeatedly measured ANCOVA at the level of .05. The results showed that the mean difference of ROM of Lt. knee flexion, Rt. knee flexion, Lt. ankle plantarflexion, Rt. ankle plantarflexion, Lt. ankle dorsiflexion, and Rt. ankle dorsiflexion were significantly different between groups (p = .015, .002, .011, .004, .000, and .000, respectively). Vertical jump performance was significantly different between groups (p = .026). Thai massage program was able to increase ROM of the lower extremities and jump performance. Thai Massage was able to warm for improving performance in competition.

The Trochlear Cleft

The trochlear cleft is a recently described vertically oriented, low-signal cartilage lesion centered in the trough of the trochlear cartilage. The purpose of our study was to determine the incidence of clefts in an at-risk group of athletes and correlate these findings with clinical and physical examination results. Sixteen female collegiate volleyball players consented to bilateral knee evaluations, which consisted of history, physical examination, and magnetic resonance (MR) imaging. Two fellowship-trained musculoskeletal radiologists reviewed each MR study by consensus. The trochlear cartilage was considered to be either normal, at risk of developing a cleft, or meeting the previously described criteria for clefts. The Fisher exact test was used for categorical variables, and the Mann-Whitney U test was used for nonparametric continuous variable. A total of 16 athletes (32 knees; 16 women; age range, 18-22 years; mean, 19.9 years) were enrolled in the study. Four knees (13%) in 3 athletes were diagnosed with a trochlear cleft; 6 knees (19%) in 4 athletes had clefts or were at risk of developing clefts. Among those players with unilateral cartilage lesions, 67% had contralateral abnormalities (P = 0.0783). Functional outcomes and physical examination findings were within normal limits for all athletes, with no difference noted between those with and without clefts. Elite athletes have a much higher incidence of trochlear clefts than the general population and are at risk of bilateral disease. Clefts are likely to be an incidental finding at MR imaging for unrelated symptoms.

Passion and Coping: Relationships With Changes in Burnout and Goal Attainment in Collegiate Volleyball Players

This study examined the relationship between harmonious and obsessive passion and coping, and assessed whether coping mediated the relationship between passion types and changes in burnout and goal attainment. College- and university-level volleyball players (N = 421) completed measures of passion, coping, burnout, and goal attainment at the start and end of a season. Results of structural equation modeling, using a true latent change approach, supported a model whereby types of passion were indirectly related to changes in burnout and goal attainment via coping. Harmonious passion was positively related to task-oriented coping which, in turn, was positively associated with change in goal attainment. Obsessive passion was positively associated with disengagement-oriented coping which, in turn, was positively and negatively associated with changes in burnout and goal attainment, respectively. This study identifies coping as a reason why passionate athletes may experience changes in burnout and goal attainment over the course of a season.

Dietary Habits, Menstrual Health, Body Composition, and Eating Disorder Risk Among Collegiate Volleyball Players: A Descriptive Study

Volleyball is typically considered a non-aesthetic sport. However, the revealing nature of volleyball uniforms may place additional pressure on female volleyball players to be thin and increase the risk of disordered eating. The purpose of this study was to provide descriptive data concerning the body composition, nutritional habits, eating disorder risk, and menstrual health of collegiate volleyball players. Female collegiate volleyball players (N = 14) completed a 7-day food record, menstrual health questionnaire, and EAT-26 survey. Participant body composition was determined using a 3 site skinfold test and the Bod Pod®. Half (50%) of participants were deemed “At-Risk” (AR) for disordered eating according to EAT-26 results, while the other half were consider “Not At- Risk” (NR). Participants consumed inadequate calories (1928 + 476) meeting only 69.35% of their predicted energy expenditure (2780.66 + 148.88). Additionally, all participants were below the recommended CHO intake range of 6-10g/kg/day for athletes (3.49 + 0.89g/CHO/kg/day) and the recommended intake range of 1.2-1.7 g/kg/day for protein for athletes (1.17 + 0.35). Body fat percentage using the Bod Pod® (22.76 + 6.25%) was similar to values reported by other studies. Seven of the participants were currently using oral contraceptives (OC). Menstrual dysfunction was reported by 3 participants not using OC. Of those using OC, 3 reported irregular menses as the reason for taking OC. No significant difference existed in macronutrient and energy intake, prevalence of menstrual dysfunction, or body composition between AR and NR groups. In conclusion, the current study suggests that collegiate female volleyball players’ diets tend to be inadequate in calories, protein, and carbohydrates, placing them at risk for subsequent medical ailments including menstrual dysfunction.

Effects of Depth Jump vs. Box Jump Warm-Ups on Vertical Jump in Collegiate vs. Club Female Volleyball Players

Introduction: Box jumps and depth jumps might elicit post activation potentiation, which can increase vertical jump performance. Aim: The purpose of this study was to compare the potentiating effects of a depth jump vs. a box jump warm-up on vertical jump performance. Methods: Eight collegiate and nine club female volleyball players participated on three testing days separated by 48 hours. Participants performed three pre-test countermovement vertical jumps with arm-swing then completed three experimental conditions in random order: control (no intervention), box jump (onto a box), and depth jump (stepping off a box with immediate maximal rebound). They then performed three post-test jumps. Results: Analysis revealed no significant (P < 0.05) interactions, but there was a main effect for time with all scores decreasing: vertical jump height (pre-34.31 ± 5.89cm; post-33.17 ± 5.86cm), relative ground reaction force (pre-24.18 ± 3.66N/kg; post-23.53 ± 3.66N/kg), and take-off velocity (pre-2.53 ± 0.29m/s; post-2.49 ± 0.30 m/s). Conclusions: It was concluded that using 10 depth or box jump warm-ups at the box height used in this study, with 10 minutes rest is not recommended to increase subsequent vertical jump performance in female collegiate volleyball players.

Well-being in volleyball players: Examining the contributions of independent and balanced psychological need satisfaction

Objectives The purpose of this investigation was to test associations between the fulfillment of basic psychological needs and two dimensions of psychological well-being using (a) an additive model and (b) a balanced model. Design This study employed a non-probability based sampling and a cross-sectional design. Methods Collegiate volleyball players ( N = 219; n females = 127) completed a battery of self-report instruments. Results Aligned within Basic Psychological Needs Theory ( Deci & Ryan, 2002) and study hypotheses ( Sheldon & Niemiec, 2006), results demonstrated that basic psychological need fulfillment was associated with psychological well-being in the context of volleyball ( R 2 adj ranged from 0.20 to 0.35). Balanced psychological need fulfillment was generally predictive, albeit minimally, of well-being indices beyond the contributions made by perceived competence, autonomy and relatedness. Conclusions This investigation highlights the need for further study of BPNT in the realm of sport including assessments of balanced need satisfaction on markers of well-being.

Effect of Four Different Starting Stances on Sprint Time in Collegiate Volleyball Players

Starting stance plays an important role in influencing short-distance sprint speed and, therefore, the ability to reach a ball during sport play. The purpose of this study was to evaluate 4 different starting stances on sprint time. Twenty-six male and female collegiate volleyball players volunteered to participate in 1 testing session. Each subject performed 3 15-ft sprint trials at each of 4 different starting stances (P-parallel, FS-false step, S-staggered, and SFS-staggered false step) in random order. Analysis of variance revealed that there was no significant interaction of sex by stance, but there were main effects for sex (men were faster than women) and stance. The FS (1.18 ± 0.10 seconds), S (1.16 ± 0.07 seconds), and SFS (1.14 ± 0.06 seconds) stances were faster than the P (1.25 ± 0.09 seconds) stance, and the SFS stance was faster than the FS stance. This indicates that starting with a staggered stance (regardless of stepping back) produced the greatest sprinting velocity over the initial 15 feet. Although taking a staggered stance seems counterproductive, the resultant stretch-shortening cycle action and forward body lean likely increase force production of the push-off phase and place the total body center of mass ahead of the contacting foot, thereby, decreasing sprint time.

Upper Limb Biomechanics During the Volleyball Serve and Spike

Background:The shoulder is the third-most commonly injured body part in volleyball, with the majority of shoulder problems resulting from chronic overuse.Hypothesis:Significant kinetic differences exist among specific types of volleyball serves and spikes.Study Design:Controlled laboratory study.Methods:Fourteen healthy female collegiate volleyball players performed 5 successful trials of 4 skills: 2 directional spikes, an off-speed roll shot, and the float serve. Volunteers who were competent in jump serves (n, 5) performed 5 trials of that skill. A 240-Hz 3-dimensional automatic digitizing system captured each trial. Multivariate analysis of variance and post hoc paired t tests were used to compare kinetic parameters for the shoulder and elbow across all the skills (except the jump serve). A similar statistical analysis was performed for upper extremity kinematics.Results:Forces, torques, and angular velocities at the shoulder and elbow were lowest for the roll shot and second-lowest for the float serve. No differences were detected between the cross-body and straight-ahead spikes. Although there was an insufficient number of participants to statistically analyze the jump serve, the data for it appear similar to those of the cross-body and straight-ahead spikes. Shoulder abduction at the instant of ball contact was approximately 130° for all skills, which is substantially greater than that previously reported for female athletes performing tennis serves or baseball pitches.Conclusion:Because shoulder kinetics were greatest during spiking, the volleyball player with symptoms of shoulder overuse may wish to reduce the number of repetitions performed during practice. Limiting the number of jump serves may also reduce the athlete’s risk of overuse-related shoulder dysfunction.Clinical Relevance:Volleyball-specific overhead skills, such as the spike and serve, produce considerable upper extremity force and torque, which may contribute to the risk of shoulder injury.

The Impact of Feedback on Dietary Intake and Body Composition of College Women Volleyball Players Over a Competitive Season

The purpose of this study was to examine the impact of nutritional feedback on dietary intake and body composition of college women volleyball players. Eight members of an National Collegiate Athletic Association (NCAA) division II women's volleyball team participated as subjects. Three-day diet records and body composition (via air displacement plethysmography) were analyzed at the beginning of the season (Beginning), peak training during the season (Peak), and 1 week postseason (After). During the first season (Baseline), the athletes were given no information concerning their dietary intakes. In the following year (Feedback), athletes were given information with regard to dietary intakes of themselves and the team as a whole. Percent body fat was not significantly different between Baseline and Feedback trials. During Beginning and Peak, the mean energy intakes ranged from 35.3 to 40.8 kcal.kg.bw. Protein intake was significantly greater in Feedback-Beginning (1.5 +/- 0.9 gxkgxbw) compared to Baseline-Beginning (1.1 +/- 0.1 gxkgxbw). No significant differences were seen in Baseline vs. Feedback for either carbohydrate or fat intakes. The only vitamin with significantly different consumption was vitamin C, with intakes of Feedback-Beginning (303.8 +/- 99.8% Dietary Reference Intakes [DRI]) vs. Baseline-Beginning (115.3 +/- 32.3% DRI). A significantly greater amount of calcium was consumed at Feedback-Beginning (152.0 +/- 25.2% DRI) compared to Baseline-Beginning (102.2 +/- 21.2% DRI). In conclusion, dietary feedback resulted in increased intake of protein, vitamin C, and calcium at the beginning of the season only for female collegiate volleyball players. Other than an increase in fiber, dietary intake at the peak of the season and postseason was not influenced by feedback. Body composition was unaffected by feedback at Beginning, Peak, and After.

Effect Of Starting Stance On Sprint Time In NAIA Volleyball Players

Foot position (i.e. starting stance) likely plays an important role in influencing short-distance sprint speed, and therefore, the ability to reach a ball. The purpose of this study was to evaluate four different starting stances on sprint speed. Twenty-six NAIA collegiate volleyball players, (age men 20.85 ± 2.79 yrs, women 19.31 ± 1.25 yrs, height men 191.28 ± 8.51cm, women 179.16 ± 7.73cm, mass men 83.52 ± 11.77kg, women 69.43 ± 9.74kg) volunteered to participate in one testing session. Each subject warmed up with a 3-lap jog around the volleyball court. Following warm-up, subjects performed twelve 15ft sprints, completing three trials each of four starting stances (parallel [P], false-step [FS], staggered [S], and staggered false-step [SFS]). Investigators randomized stance order. A 2 x 4 (sex x condition) mixedfactor repeated measures ANOVA revealed there was no significant interaction of sex and condition; however, there were main effects for sex and condition. The main effect for sex demonstrated that males were faster than females. Players ran significantly slower using the P stance (1.25 ± 0.09 s) than any other starting stance (SFS = 1.14 ± 0.06 s, S = 1.16 ± 0.07 s, FS = 1.18 ± 0.10 s). The SFS stance produced faster speeds than the FS stance. This study indicates that starting with a staggered stance (whether employing a false step or not) produces the greatest sprinting velocity over the initial 15ft. Although taking a false-step seems counterproductive, the resultant stretch-shortening cycle likely increases force production of the push off phase and therefore, sprint speed. The S stance might produce greater speeds by reducing movement time in response to a stimulus. Volleyball players might increase their sprint speed by utilizing either a staggered false-step or a staggered stance prior to accelerating.

Effect Of Weighted Jump Warm-Up On Vertical Jump In Division II Female Volleyball Players

Dynamic warm-up strategies are designed to positively impact performance. Research suggests that warm-ups which elicit a post activation potentiation (PAP) effect via high intensity muscular contractions may increase performance in subsequent activities requiring strength and power. The purpose of this investigation was to determine if a functional, dynamic, volleyball specific warm-up that included weighted jumps would elicit a PAP effect and increase subsequent vertical jump height. Ten trained female Division II volleyball players participated (age = 19.8 + 1.8 yrs; mass = 71.7 + 9.7 kg; ht = 167.8 + 23.9 cm). Subjects were at week 6 of their off-season conditioning program. Besides volleyball specific strength and conditioning, per NCAA guidelines, each player accumulates 2 hrs/wk of individual volleyball practice during this time period. Two different warm-up conditions lasting ∼ 5-7 minutes were individually employed at two different training sessions within one week. The first warm-up condition consisted of a functional, dynamic warm-up of light jogging, high knees, carioca, shuffling, ankle pops (all at 3 sets at 20 yds ea.), pogos (2 × 15 sec.), and tuck jumps (1 × 15 sec.). The second warm-up condition was identical to the first, except for the addition of 1 × 10 maximal vertical jumps with countermovement while wearing a weight vest loaded with 20% of their individual bodyweight. Starting at 4-minutes post warm-up in each condition, maximal vertical jump was assessed in two conditions: 1) 2-hand standing block vertical jump (SBVJ), and 2) 1-hand 3-step approach vertical jump (AVJ). Three trials per each condition were given, with 15 sec. rest intervals allowed between trials. The highest point touched on a vertical jump tester was recorded for each trial. The average of the three trials was used for data analysis. Paired Samples T-test was used to determine if there was a significant difference (p < 0.05) in vertical jump height (i.e., height touched) between the two conditions. The results of this study were mixed. No significant difference (p > 0.05) occurred in vertical jump height in the SBVJ condition between the two different warm-ups (262.1 vs. 263.0 cm, warm-up vs. warm-up with weight vest, respectively). However, the AVJ was significantly higher by 2.7 cm (p < 0.05; 275.1 vs. 277.8 cm) after the subjects added the weight vest to their warm-up routine. This study demonstrates that a functional, dynamic warm-up with the addition of weight jumps for 1 × 10 at 20% of bodyweight increases 3-step approach vertical jump ability in female collegiate volleyball players. However, no effect was seen in 2-hand standing block vertical jump ability. This may possibly be explained by the difference in the forces and energy involved during the stretch-shortening cycle in a 3-step approach vertical jump vs. a stationary standing block vertical jump. The coach may consider using a functional, dynamic, athletic warm-up that includes jumps with resistance to optimize performance in sports like volleyball where vertical jumps with an approach are key components of competition.
