J Strength Cond Res 23(2): 495-506, 2009-Plyometric training improves vertical jump height (VJH). However, the effectiveness of plyometric training depends on various factors. A meta-analysis of 56 studies with a total of 225 effect sizes (ESs) was carried out to analyze the role of various factors on the effects of plyometrics on VJH performance. The inclusion criteria for the analysis were a) studies using plyometric programs for lowerlimb muscles, b) studies employing true experimental designs and valid and reliable measurements, and c) studies including enough data to calculate ESs. Subjects with more experience in sport obtained greater enhancements in VJH performance (p , 0.01). Subjects in either good or bad physical condition benefit equally from plyometric work (p , 0.05), although men tend to obtain better power results than women after plyometric training (p , 0.05). With relation to the variables of performance, training volumes of more than 10 weeks and more than 20 sessions, using high-intensity programs (with more than 50 jumps per session), were the strategies that seemed to maximize the probability of obtaining significantly greater improvements in performance (p , 0.05). To optimize jumping enhancement, the combination of different types of plyometrics (squat jump + countermovement jump + drop jump) is recommended rather than using only 1 form (p , 0.05). However, no extra benefits were found to be gained from doing plyometrics with added weight. The responses identified in this analysis are essential and should be considered by strength and conditioning professionals with regard to the most appropriate doseresponse trends for optimizing plyometric-induced gains. R = rest (s); VJG = vertical jump gains (cm).

The aim of the study was to evaluate the impact of an 8-weeksplyometric training program on the sprint and jump performance. The intervention study employed a controlled experimental design with two parallel groups of male long jumpers. While the experimental group (n = 18) trained with plyometric exercises, the control group (n=10) performed classical long jump training. Both groups were examined for athletic performance (30m sprint, standing long jump, vertical jump) and biomechanical parameters of a long-jump movement (max vertical height, horizontal and vertical velocity at takeoff , flight time, takeoff duration) prior and following the intervention. The experimental group demonstrated significantly better developments than the control group in most of the physical and biomechanical parameters respectively and improved their long jump records. Combining an 8-weeksplyometricprogram with athletics training significantly develops long jump and general athletic performance as well as biomechanical parameters. Therefore, plyometric training can be recommended to athletics coaches as an additional training alternative to improve sprint and long jump abilities in athletes.
Effect of plyometric training on improving vertical jump in female footballers (14-17 years old)
Turkish Journal of Kinesiology
Plyometric training (PT) is a very popular form of physical conditioning for healthy individuals that have been extensively studied over the last decades. The study aimed to determine the effect of PT on improving vertical jump (VJ) in female footballers (14-17 years old). The study adopted a pretest-posttest quasi-experimental design. The study population was the female football players of the National Women's Football League in Algeria (LNFF). Twenty-two players were drawn from the study population (age=15.10±0.47 years, height=152.01±5.80 cm, weight=49.51±6.09 kg). The sample was divided into a control group (CG) and an experimental group (EG). Eleven players per group. The training program was made for the participants and the exercise training was supervised by the researchers. The PT exercises for the EG in which each exercise session involved 15±3 minutes of moderate-intensity exercise for the first four weeks and gradually increased to high-intensity exercises for the la...
Impact of plyometric training and weight training on vertical jumping ability
The Purpose of the study was to find out the comparative effect of Plyometric and weight training on vertical jumping ability. For the present study 24 male students from Department of Physical Education, BHU Varanasi were selected randomly as the subjects for the study. The age of the subjects ranged between 18-21 years. The variables selected for the present study were Plyometric and weight training (independent variable), vertical jumping ability (dependent variable). For the study pre test – post test randomized group design, which consists of control group (08 students) and two experimental groups (16 students) were used. The data were collected through the pre test, before training and post test, after six weeks of Plyometric and weight training. To find out the comparative effect of Plyometric and Weight Training on vertical jumping ability of the subjects the pre test and post test scores were analyzed by using Descriptive analysis, Analysis of Co-Variance (ANCOVA) and LSD test were used, the data analyzed with the help of SPSS (16.0 version) software and the level of significance was set at 0.05 level of confidence. The result of the study showed that there was significant difference between pre and post test (experimental group) of Jump & Reach and Approach Jump & Reach. Significant difference was found between adjusted means of Plyometric training and control group, weight training and control group in relation to jump and reach performance (p< 0.05). In relation to approach jump and reach performance significant difference was found between adjusted means of Plyometric training and control group, weight training and control group since the p< 0.05. On the basis of findings of the study it may be considered that Plyometric training could be very much useful method of training for sportsman to improve vertical jumping ability and to retain the same for a longer duration.

Recently, there has been a proliferation of published articles on the effect of plyometric jump training, including several review articles and meta-analyses. However, these types of research articles are generally of narrow scope. Furthermore, methodological limitations among studies (e.g., a lack of active/passive control groups) prevent the generalization of results, and these factors need to be addressed by researchers. On that basis, the aims of this scoping review were to (1) characterize the main elements of plyometric jump training studies (e.g., training protocols) and (2) provide future directions for research. From 648 potentially relevant articles, 242 were eligible for inclusion in this review. The main issues identified related to an insufficient number of studies conducted in females, youths, and individual sports (~ 24.0, ~ 37.0, and ~ 12.0% of overall studies, respectively); insufficient reporting of effect size values and training prescription (~ 34.0 and ~ 55.0% o...

Background The aim of this study is to conduct a systematic review with meta-analysis to explore the effects of plyometric jump training (PJT) on the physical fitness of individual sport athletes (ISA). Methods Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched through PubMed, Web of Science, and SCOPUS electronic databases. We included controlled studies that incorporated a PJT intervention among ISA (with no restriction for age or sex), that included a pre-to-post intervention assessment of physical fitness (e.g., sprint; jump). From the included studies, relevant data (e.g., PJT and participants characteristics) was extracted. We assessed the methodological quality of the included studies using the PEDro scale. Using a random-effects model, meta-analyses for a given outcome was conducted. Means and standard deviations for a measure of pre-post-intervention physical fitness from the PJT and control groups were converted to Hedg...
The effect of an 8 week plyometric training program on sprint and jumping performance
Alptekin et al.: Effect of plyometric training on sprint and jumping performance Serb J Sports Sci 7(2): 45-50 Abstract: The purpose of this study was to examine the effects of 8 weeks' plyometric training on active jump, squat jump and 30 m sprint in 13-15-year-old football players. The study consisted of 24 volunteer football players from Pamukkale Sport Club U-13 and U-15. Participants were assigned equally to either the control group (Age = 13.71 ± 0.53 years old, BH = 1.63 ± 0.06 m, BM = 53.07 ± 3.76 kg) or the training group (Age = 13.69 ± 0.55 years old, BH = 1.63 ± 0.08 m, BM = 55.00 ± 12.85 kg). Before the training program, all players' anthropometric measurements were taken. All players performed active jump, squat jump and 30 m sprint test, and pre-and post-test results were recorded. The training group carried out a basic training program plus a set of plyometric exercises twice a week for 8 weeks. The control group carried out the basic training program only. Pr...

Plyometric training (PT) enhances soccer performance, particularly vertical jump. However, the effectiveness of PT depends on various factors. A systematic search of the research literature was conducted for randomized controlled trials (RCTs) studying the effects of PT on countermovement jump (CMJ) height in soccer players. Ten studies were obtained through manual and electronic journal searches (up to April 2017). Significant differences were observed when compared: (1) PT group vs. control group (ES=0.85; 95% CI 0.47-1.23; I2=68.71%; p<0.001), (2) male vs. female soccer players (Q=4.52; p=0.033), (3) amateur vs. high-level players (Q=6.56; p=0.010), (4) single session volume (<120 jumps vs. ≥120 jumps; Q=6.12, p=0.013), (5) rest between repetitions (5 s vs. 10 s vs. 15 s vs. 30 s; Q=19.10, p<0.001), (6) rest between sets (30 s vs. 60 s vs. 90 s vs. 120 s vs. 240 s; Q=19.83, p=0.001) and (7) and overall training volume (low: <1600 jumps vs. high: ≥1600 jumps; Q=5.08, p...

The purpose of this study was to compare the effects of 3 different training protocols-plyometric training, weight training, and their combination-on selected parameters of vertical jump performance and leg strength. Forty-one men were randomly assigned to 1 of 4 groups: plyometric training (n ϭ 11), weight training (n ϭ 10), plyometric plus weight training (n ϭ 10), and control (n ϭ 10). Vertical jump, mechanical power, flight time, and maximal leg strength were measured before and after 12 weeks of training. Subjects in each training group trained 3 days per week, whereas control subjects did not participate in any training activity. Data were analyzed by a 2-way (4 ϫ 2) analysis of variance (repeated-measures design). Results showed that all training treatments elicited significant (p Ͻ 0.05) improvement in all tested variables. However, the combination training group produced improvements in vertical jump performance and leg strength that were significantly greater than improvements in the other 2 training groups (plyometric training and weight training). This study provides support for the use of a combination of traditional and Olympic-style weightlifting exercises and plyometric drills to improve vertical jumping ability and explosive performance in general.
Effects of a plyometric program on vertical landing force and jumping performance in college women
Physical Therapy in Sport, 2008
Objectives: To examine the effects of a plyometric program on peak vertical ground reaction force as well as kinetic jumping characteristics in recreationally athletic college women. Design: Six week prospective exercise intervention. Setting: Division I university campus. Participants: Twenty college females who competed recreationally in basketball were randomly assigned to a training (n ¼ 10) or control (n ¼ 10) group. Main outcome measures: The absolute change values for vertical ground reaction force, countermovement jump height, peak and average jump power, and peak jump velocity. Comparisons were made using Mann-Whitney U tests. Results: Vertical ground reaction force decreased in the intervention group (À222.87610.9 N), but was not statistically different (p ¼ 0.122) compared to the change observed in the control group (54.67257.6 N). There was no difference in the absolute change values between groups for countermovement jump height (1.072.8 cm vs. À0.271.5 cm, p ¼ 0.696) or any of the associated kinetic variables following the 6-week intervention. Conclusions: Although not statistically significant, the mean absolute reduction in vertical ground reaction force in the training group is clinically meaningful. Eight of the 10 women in the training group reduced vertical ground reaction force by 17-18%; however, improvements in jumping performance were not observed. This indicates that programs aimed at enhancing performance must be designed differently from those aimed at reducing landing forces in recreationally athletic women. r
