Purpose: To examine the effect of a 10-week plyometric training (PT) on the kinematic and kinetic properties of prepubescent girls during squat jump, countermovement jump, and drop jumps. Methods: Twenty-four untrained girls (aged 9–11 y) were assigned to a training group (TG) and a control group. The TG followed twice a week PT for 10 weeks. Squat jump, countermovement jump, and drop jumps performed from heights of 20, 35, and 50 cm were tested before and after PT. Jump height, kinematic, and kinetic parameters were evaluated using a motion analysis system and a force plate. Results: Jumping height in all jump types increased significantly after PT for the TG (P < .001). After training, the TG presented increased power (P < .001) and knee angular velocity (P < .001), higher knee flexion at the deepest point during the braking phase (P < .001), longer contact time (P < .001), and unchanged stiffness and reaction strength index (P > .05). No differences were observed in the control group (P > .05). Conclusion: These findings indicate that a 10-week PT positively affected jumping performance in prepubescent girls who improved their drop jump performance after training not by adopting a stiff/bouncing jumping style of short contact time and increased stiffness, but a compliant/absorbing style of prolonged contact time.

Abstract This study compared the effects of unilateral and bilateral plyometric training on strength, sprint performance and lower limb power. Sixty-eight preadolescent soccer athletes were randomly assigned to a unilateral plyometric training group (n=23), a bilateral plyometric training group (n=23) and a control group (n=22). Both plyometric training groups trained with equal volumes of unilateral or bilateral exercises for 15 minutes in each session, at which time the control group performed soccer-specific drills. Plyometric exercises were executed twice weekly for 10 weeks during the competitive season. The following tests were performed before and after the intervention: single-leg and double-leg countermovement jump, squat jump, horizontal jumps in different directions, maximal isometric strength of quadriceps and hamstrings, sprint performance, agility and balance. Unilateral plyometric training resulted in greater improvements compared to the control group in the following variables: hamstrings strength (ES: 0.91, p=0.037), 5m sprint time (ES: 0.93, p=0.004), single-leg countermovement jump (ES: 0.90, p=0.006), single- and double-leg squat jump (ES: 0.87, p=0.030 and ES: 0.73, p=0.067, respectively) and single-leg hop performance (ES: 1.01, p=0.004). The only tests where there was an improvement of BPT compared with the CG were the single-leg and double leg SJ (ES: 0.76, p=0.026; ES: 0.70, p=0.050). Quadriceps strength, side hop test, double-leg horizontal jump test, flamingo balance test and modified agility T-test were equally improved in all three groups (p<0.001). In conclusion, unilateral lower-limb plyometric training is more effective in increasing muscle strength and power in preadolescent soccer players when compared to bilateral training or soccer training alone.

This study was done with the aim of determining the effects a programmed training would have on the changes in the explosive strength of young female volleyball players. The sample consisted of 30 female volleyball players, aged 14 to 16, divided into two groups – the experimental one (n=15) and the control group (n=15). The experimental group was comprised of the players from the club OK ‘Desetka’, who, apart from the basic technical and tactical training process, underwent a specially designed programme for developing explosive strength two times a week (on Tuesdays and Thursdays). The experimental programme was applied during the period of preparations before the official beginning of the regional competitions for cadets. The control group was comprised of the players from the club OK ‘Millennium’, who, during the same period of time, underwent only those training sessions which had previously been planned within the annual plan and programme of the club. Explosive strength evaluation included four sets of tests: the squat jump (SJ), countermowement jump (CMJ), drop jump (DJ), one-legged CMJ (OLCMJ). The effects of the progremmed training on the development of the explosive strength of the young female volleyball players was determined by the Covariance Analysis, ANCOVA. The results obtained in such a way showed the statistically significant improvement in the parameters tested within the experimental group. The difference was insignificant in the OLCMJ test only. The results point to the conclusion that the experimental training programme had positive effects on the changes of explosive strength of young female volleyball players.

The primary objective of this study was to design a digging agility system that was used to analyze the effectiveness of 6 weeks of plyometric training on volleyball players. A total of 24 highly trained college male volleyball players were recruited for this study. The players were equally divided into a plyometric training group and a control group. The agility T-test, peak power output test, 10-meter sprint, and digging agility test were used to examine the effects of plyometric training on the digging agility of volleyball players. One-way analysis of covariance was conducted to examine the differences in the variables between groups. The results reveal that after 6 weeks of plyometric training, the plyometric training group had significant improvements on the agility T-test, digging agility test, and peak power output tests, with statistical power values all greater than 90%. The plyometric training group significantly improved by 2.68% on the agility T-test, 2.35% on the digging agility test, and 7.32% on the peak power output test. The results indicated that appropriate plyometric training can enhance the agility of lateral movements and peak output of vertical jumps, as well as enable players to rapidly complete movements during a moving defense.

The development of muscle power should be taken into account in soccer training. The aim of this study was to evaluate the influence of a 6-week of mixed power training on the level of the motor skills of the lower limbs of young soccer players. The training was conducted during the starting period. The study included twelve 16-18-year-old players who regularly participated in specific soccer trainings and played in regional competitions. Their basic anthropometric features were measured. The assessment of the power of the lower limbs was carried out using two jump tests: CMJ and SJ. The maximum anaerobic power was calculated and was expressed in relation to body weight and lean body mass. In addition, Drop Jump tests were performed from three different heights on the basis of which RSI reactive strength index were calculated. On completion of the training program an increase in the level of the results of all the tests was observed: SJ (cm) (cohen's d: 0.43), CMJ (cm) (cohen's d: 0.33), SJPmax (W/kg) (cohen's d: 0.43), CMJPmax (W/kg) (cohen's d: 0.30), SJPmax (W/LBMkg) (cohen's d): 0,57), CMJPmax (W/LBMkg) (cohen's d: 0,44), RSI 0,2 (cohen's d: 0,59), RSI 0,3 (cohen's d: 0,45), RSI 0,4 (cohen's d: 0,58). An additional six-week ballistic-plyometric training program, used as a supplement to the basic training plan during the start period, resulted in an increase in the motor skills of the lower limbs of young soccer players. The application of combined ballistic and plyometric training methods helps to improve the strength and speed potential of young soccer players.

The aim of this study was to determine the effects of plyometric training on sprint abilities. Young basketball players (N=33, Age=15-16) from OKK "Stari Ras" and OKK "Novi Pazar" from Novi Pazar were divided into two groups: an experimental group (EG, n=16; BH=185.45±8.75cm; BM=76.87±11.51kg) with training experience (TE=4.69 ±1.40 years) and a control group (CG; n=17; BH=184.16±6.93cm; BM=76.87±11.51kg) with training experience (TE=5.53±3.18 years). The EG was made up of the players from basketball team OKK "Stari Ras", who in addition to basketball trainings also took part in plyometric training. The CG was made up of the players from basketball team OKK "Novi Pazar", who at that time only took part in basketball trainings. To assess their sprint abilities, three tests were used: Sprint Speed at 5m (S5m), Sprint Speed at 10m (S10m), Sprint Speed at 20m (S20m). The measurement was done with the help of the photocells "Microgate", a parameter which was monitored and the processed time was read in 1/100s. The experimental program lasted for 10 weeks (2x per week). To determine the effect of plyometric training on the sprint abilities of young basketball players, the analysis of covariance ANCOVA was used. The results showed that the EG group achieved significantly greater progress than the CG group on the tests: S5m and S20m. There was no difference between the EG and CG group on the S10m test. Based on these results we concluded that plyometric training has positive effects on the development of sprint abilities in young basketball players.

ABSTRACT Introduction: Plyometric training significantly improves strength performance, including in aquatic sports. Objective: To compare changes in thigh girth, hamstring flexibility, squat jump height, and 200m swimming trial time induced by plyometric training in recreationally-trained swimmers. Methods: Eighteen recreationally-trained male swimmers (age=18-20 years) were randomly divided into a plyometric training group (PTG) and a control group (CG). All the swimmers completed a six-week speed swimming training plan. In the PTG only, the last ~15 min of each session was replaced with plyometric exercises. The physical characteristics and the thigh girth were measured before and after the six weeks of training. In addition, sit-and-reach flexibility and squat jump tests were conducted, as well as a 200m swimming trial. Results: Two-way ANOVA with post-hoc analysis revealed an increase in sit-and-reach flexibility (PRE: 4.5±5.3 cm; POST: 10.9±5.9 cm, p<0.01) and squat jump height (PRE: 24.9±3.7 cm; POST: 28.3±4.2 cm, p<0.01) and a decrease in 200m-swimming time (PRE: 220±26.5 sec; POST: 204±24.4 sec, p<0.01) for the PTG only. Comparing the absolute changes (post-pre) between the groups by the Student's t-test, the PTG showed a greater increase in distance reached in the sit-and-reach flexibility (PTG: 6.34±0.6 cm vs. CG: 2.4±1.2 cm, p<0.01) and squat jump height (PTG: 3.4±0.7 cm vs. CG: 0.7±0.3 cm, p<0.01) than the CG. In addition, the 200m swimming time decreased significantly more than in the CG (PTG: -15.1±2.4 sec vs. CG: -0.8±2.7 sec, p<0.01). Conclusion: Plyometric training improves jump height, flexibility, and 200m swimming performance in recreationally-trained adult swimmers. Level of Evidence II; Lesser quality RCT.

The knowledge gained through this study could help to make plyometric training more effective when Proprioceptive Neuromuscular Facilitation (PNF) stretching added to the workouts without having to isolate strength and flexibility on separate sessions. The aim of this study was to compare the individual and combined effects of 6-week of PNF stretching and plyometric training (PLYOT) in muscular power and flexibility for young volleyball players Thirty-seven male young volleyball players participated in the current study. They were distributed into four groups; PNF (n = 10), PLYOT (n = 10), Combining PNF and PLYOT (COMB) (n = 10), and control group without PNF and PLYOT (CON) (n = 7), they were tested before (PRE) and after (POST) 6-week training for muscular power [i.e. vertical jump (VJ), seated medicine ball throw (SMTH), and rotational power ball throw (RPTH)] and flexibility [i.e. sit& reach test (SRT), shoulder& wrist flexibility test (SWFT), and trunk rotation test (TRT)]. The results have shown significant effects of the time for all study variables (p ≤ 0.05) of all groups except CON group had no significant effects (p ˃ 0.05). There were statistically significant differences favor COMB group (p ≤ 0.05) at the POST evaluation in muscular power variables in comparison with the PNF and PLYOT groups, while no statistically significant differences (p ˃ 0.05) were found between PNF, PLYOT, and COMB in all flexibility variables. In conclusion the combined effect of PNF and PLYOT has surpassed the individual effect of them on muscular power but not on flexibility variables.
