The Relationship

Few data exist on the relationship between maximum strength and power performance, such as jumping ability in low-level female volleyball players. The aim of the present study was to determine the relationship between maximum strength and jumping performance in young female non-elite volleyball players before and after an in-season resistancetraining protocol. A 26-week, in-season resistance-training program was carried out on ten female volleyball players, aged 19 (±2). The 1 RM squat test was used to evaluate the players’ maximum strength in the lower extremities and a vertical jump (VJ) test was used to assess functional performance and power. There was a significant enhancement of 69% (p=0.005) for the squat test and 9% for the VJ test (p=0.008). A strong significant relationship was found between the VJ test and the 1 RM squat test (r=0.68, r2=0.47, p=0.0014) at the pre-test and post-test (r=0.88, r2=0.77, p=0.001). When comparing the coefficients of correlation (r=0.68 and r=0.88) between the squat tests and VJ tests, the difference that was noted was significant (p<0.001). A strong significant relationship was also noted between the 1RM squat and VJ test relative to body weight at pre-test (r=0.89, r2=0.79, p=0.001) and post-test (r=0.95, r2=0.90), p<0.001). This study demonstrates that maximum strength in squats is a major predictive factor for jumping height in young female volleyball players. Female volleyball players might therefore consider focusing on maximum strength training to improve their jumping performance.

The Relationship

Volleyball is characterized by the activity of vertical jump performance in the technical elements of attack, block and service. The study focuses on young Female & Male players during the 12-week plyometric training. The objective of this study  is  to  evaluate  the  effects  of  12-weeks  plyometric training  performance  in volleyball players M & F in Albania to see the differences between them. Methods; 40 young players (F & M) participated in this study. N=10 M & N=10 F volleyball players considered as Experimental and the same number as Control. The average age of players included in this study is 17-18 years old. The players of both groups were evaluated before and after 12 weeks. The F&M Experimental groups conducted 12 weeks of plyometric training with 2 sessions for a week. The F&M Control groups conducted the training according to the method of their trainers. Besides anthropometric measurements they developed Drop Jump tests by jumping from the cube in height 40 cm and 60 cm. Results; The results showed a high correlation coefficient (r = 0,924) and statistically significant (p <0,05). Data obtained from two groups GRFP show that the relationship between the contact time and the time air changes between the two tests DJ 40-60cm. Conclusions. The methodology used helps us compare the high and poor performances that help coaches to program more detailed plyometric training for the development of jumping skills in young volleyball players. The effect of plyometric training developed on M&F volleyball players and according to data obtained from GRFP, showed that male volleyball players had a better performance in vertical jump than female volleyball players. Vertical jumping may be assessed not only by the height of its development but also by the phase of residence in the air.

The Relationship

Body composition and the skill of jumping are very important for high physical performance in volleyball. The purpose of this study is to analyze the relationship between body composition and jumping performance in female volleyball players aged 14-17. 74 female volleyball players volunteered to participate in the study. The height, body weight, body mass index, body fat percentage, body muscle mass and trunk fat percentage measurements were taken and the vertical jump and standing long jump tests were applied. The data were evaluated with the SPSS 16 statistical software program, the Pearson Correlation test was done for the statistical analysis and the significance level was determined as p< 0.05. The athletes’ vertical jump and standing long jump values were found statistically to have a negative relationship with height, body fat percentage, body muscle mass and body fat percentage, whereas a positive relationship was found between vertical jump and standing long jump values and body weight (p< 0.05). As a result, it was determined that body composition in volleyball players affects jumping performance.

Anaerobic Test

The aim of the present study was to evaluate the anaerobic power of elite male volleyball players, using the Wingate Anaerobic Test to examine the relationship between anaerobic power and jumping performance. Athletes ( n = 56) and Nonathletes ( n = 53) were divided into three age groups: Adults (18–25 yr.), Juniors (15–16 yr.), and Youth (10–11 yr.). Measurements of height, body mass, vertical jump and Wingate scores indicated higher values for athletes. The specific training effects of anaerobic power were more pronounced at the age of 10–11 years than for Nonathletes. A significant correlation coefficient between peak power and vertical jump was found for Athletes ( r = .86) and for the total group ( r = .82). These results indicated that vertical jump may predict the maximal anaerobic power and could be used by coaches as a practical and easy-to-apply field screening test for evaluation in volleyball training.

The aim of this study was to quantify levels of physical activity (PA) and fundamental movement skills (FMS) of children aged 3 to 5 years in Irish preschool services during care hours, and investigate the relationship between these two variables. Data were collected from 141 children (50.3% boys, age M = 3.9 ± 0.5 years) across 9 preschool services. Measurements included PA via accelerometry, and proficiency in four FMS (run, vertical jump, throw and catch). The recommended guideline of 15 minutes of PA per hour (min PA/hour) was met by 35% of children (M = 13.6 min PA/hour). Significant differences in mean PA per hour were found by gender, with boys (14.2 min PA/hour) more active than girls (13.0 min PA/ hour), and age, with younger children (14.2 min PA/hour) more active than older (12.6 minutes PA/hour). Percentage of children proficient in the run was high (88.4%), but low across the other skills (4.9%–18.5%). Significant differences were identified by gender for vertical jump with girls scoring higher than boys. No significant relationship was found between FMS and total PA. Low levels of PA and FMS proficiency highlight need for intervention in early years settings to ensure children develop skills to participate in PA.

The Relationship

The goal of the present study was to explore the relationship between maximum strength, the vertical jump, acceleration and change of direction performance in healthy young male students. The sample of variables included the following variables: body mass (BM), one repetition maximum on the half-squat test (Squat 1RM), one repetition maximum normalized for body mass (Squat 1RM_rel), peak power during the concentric phase of countermovement jump (Ppeak CMJ), vertical jump height during CMJ (CMJ_H), time for the 20m sprint (20m Srint) and time for the agility T-Test (Agility T-Test). The relationship was tested with the Pearson Coefficient of linear correlation (r). The results showed significant correlation between body mass with Squat 1RM_rel and peak concentric power during CMJ (r=-.424, and r=.377, respectively). Peak concentric power during CMJ additionally has a significant correlation with the change of direction abilities, 20m sprint, and vertical jump height, (r=-.401; r=-.467; r=.656; p<0.05, respectively). Also, significant correlation was determined between the 20m Sprint and Agility T-Test (r=.443; r=-.570, respectively), and Agility T-Test vertical jump height (r=-.498).  The level of relationships between maximum strength, acceleration, COD and CMJ may be attributable to differences in the control and coordination of several muscle groups during execution of these tests.

The purpose of this study was to compare the effects of 4 weeks plyometric training on grass surface group and concrete surface on jumping performance among volleyball athletes. The vertical jump was evaluated in two types of jump; squat jump (SJ) and countermovement jump (CMJ). The result of this study indicates that the 4 weeks intervention showed a significant improvement in post test on SJ and CMJ (p < 0.05) for both grass surface and concrete surface. However, in comparing the grass surface and concrete surface, there was no significant difference (p > 0.05). These findings suggest that plyometric training on different surfaces may be associated with similar training-induced effects on the neuromuscular factors which are related to the efficiency of the stretch-shortening cycle.

The Stability

Based on the research review, fascia-oriented training may positively influence sports performance.  Its component focused on the “catapult” mechanism can increase the capability of the connective tissue to store and release kinetic energy, which is involved in various movement actions, activities and skills including the jumping skills in volleyball. The study was conducted to assess the effect of the 6-month fascia-oriented training on the height of the vertical jump in well-trained junior female volleyball players. 16 players (age 17.31 ± 0.98; height 173 ± 5.26; weight 65.25 ± 6.75), members of one team competing in the national league, were randomly assigned for the training group (TG) and control group (CG). TG participated in a supervised 25-minute fascia-oriented training twice a week for six months. To measure the height of the jump, the force plate Bertec FP6012-15-4000 was used. Three testing measures were executed: pre-test, mid-test and post-test with three trials of the standing vertical countermovement jump with all arm movement. The study presupposed that after three months, the height of jump may rise slightly more in TG than in CG. After six months, a statistically significant increase was expected in TG compared to CG. Based on the results of the study, we conclude that the 6-month fascia-oriented training focused on the development of the height of vertical jump in well-trained junior volleyball players neither complied with the assumed dynamics in changes nor was statistically significantly beneficial. However, the dynamics of the changes indicate that fascia-oriented training may positively influence the stability and efficiency of the jumping performance during the game season.

Anthropometric Profile

This study aimed to determine the anthropometrics of athletes representing Universiti Pendidikan Sultan Idris (UPSI) during the Malaysian Inter-varsity Sports (MASUM) tournament, 2018. In this study, 50 athletes consisted of 15 hockey players, 12 netball players, 13 volleyball players and 10 volleyball players were recruited as participants. Percentage of body fat was measured using formula by Jackson, Pollock and Ward (1980) while somatotype were determine using the scale by Heath and Carter. Data were analyzed using descriptive statistics and Pearson correlation. The results of the anthropometric profile indicate that almost all teams have an endo-meso (more muscular) body, but the results of the relationship showed that significant relationship between the anthropometric profile and the performance were only found in the bowling team, r = 0.13, p = 0.14, p < 0.05. For hockey, netball, and volleyball teams did not show significant relationship (r = 0.15, p = 0.74, p> 0.05), (r = 0.12, r = 0.64, p> 0.05), (r = 10, p = 0.71, p> 0.05) respectively. In conclusion, the overall anthropometric profile cannot be indicated as determinant of a team's performance at the MASUM 2018 tournament
