“…2). This is in agreement with Young et al (1999) who showed that a 6 week plyometric program failed to improve jumping height. It could also be hypothesized that plane hopping could not load the muscles sufficiently enough to increase their strength capacity in such short training period.…”

“…Even though the majority of studies have shown a positive effect on vertical jumping performance, research on the effectiveness of plyometric training is sometimes inconclusive (Markovic 2007). Some studies have shown that training (Thomas et al 2009;Luebbers et al 2003) consisting of counter movement jumps (CMJ) or drop jumps (DJ) increases jumping height (Gehri et al 1998), while others have failed to find significant adaptations (Chimera et al 2004;Young et al 1999), despite of alterations in lower limbs muscle activity (Chimera et al 2004). These inconclusive results may be attributed to several factors such as differences in training program characteristics and type of jumping exercises (Markovic 2007).…”

Incline plyometrics-induced improvement of jumping performance

The aim of this study was to examine the effects of incline plyometrics training on muscle activation and architecture during vertical jumping and maximum strength. Twenty male participants were divided in two training groups which followed after a 4 week training program. The incline plyometrics group (n = 10) trained by performing consecutive jumps on an inclined surface (15°) while the plane plyometrics (PP) group (n = 10) performed the same jumps on a plane surface. Both groups trained four times per week and performed 8 sets of 10 jumps in each session. Subjects performed squat jumps, counter movement jumps and drop jumps (DJ) prior to and immediately after the training period, while the electromyographic activity of the medial gastrocnemius (MGAS) and tibialis anterior muscles and the architecture of MGAS were recorded. Maximal isokinetic and isometric strength of the plantar flexors were performed. Analysis of variance showed that only the IP group improved fast DJ height performance by 17.4 and 14.4% (20 and 40 cm, p < 0.05). This was accompanied by a significantly higher MGAS activity during the propulsion phase (24% from 20 cm and 50% from 40 cm, p < 0.05) of the DJ and a longer working fascicle length (5.08%, p < 0.05) compared with the PP group. There were no significant changes in isokinetic and isometric strength of the plantar flexors after training for both groups. The increase of jumping performance, after incline plyometrics should be taken into consideration by coaches, when they apply hopping exercise to improve explosiveness of the plantar flexors.

Michailidis, Y. (2015). Effect of plyometric training on athletic performance in preadolescent soccer players. J. Hum. Sport Exerc., 10(1), pp.15-23. The aim of this study was to investigate the effectiveness of plyometric training on performance of preadolescent soccer players. 21 players assigned to two groups: jumping-group (JG, n = 11) and control-group (CG, n = 10). Training program was performed for 10 weeks. Anaerobic power performances were assessed by using standing long jump (SLJ), 10 m and 30 m sprint. In the JG the performance at the long jump was increased significantly (P = 0.031). Also the performance of JG increased at 30m sprint running by 7.2 % (P < 0.001). None of the variables tested in the CG demonstrated difference between the pre-test and the post-test. Our results indicate that plyometric training can improve running performance at 30 m sprint and the performance at standing long jump in preadolescent soccer players.

“…The present study revealed non-significant changes of the optimal velocity. Considering the fact that volleyball training aimed at the improvement of players' force also enhances their power and jumping ability [18,19], the results obtained are satisfactory. It must, however, be kept in mind that a study of female volleyball players by Häkkine [10] revealed an increase in all measured parameters only until the completion of the first competitive period, after which a decrease was noted.…”

Volleyball is a sport involving short and intensive physical efforts during training and competition [1,2]. Volleyball players' fitness relies on their force, power output and jumping ability [3,4]. Although the players' power output is measured on a cycloergometer, its value depends, however, on the amount of external loading [2]. Different authors have examined the force-velocity (F-v) and power-velocity (P-v) relationships, measured during cycloergometer exercises in different groups of athletes [5,6] and discussed the effects of specific training exercises on the force-velocity relationship [7][8][9]. Their results suggest that sport training can influence the correlation mentioned [5][6][7]. With the exception of Häkkinen's work [10] discussing changes of force and jumping ability in female volleyball players during the competitive season, there have been no studies, however, examining changes in the force-velocity and power-velocity relationships in volleyball players during an annual training cycle. The aim of the present study was to follow changes of the maximal power output and powervelocity relationship in male volleyball players during an annual training cycle. Material and methodsThe study was granted approval of the Research Ethics Committee. The sample consisted of six male volleyball players from the Polish Volleyball League aged 25.0 ± 5.3 years, with body height of 195.2 ± 7.2 cm and body weight of 91.2 ± 14.7 kg. The measurements were performed before the preparatory period (I), after the first competitive season (II) and after the second competitive season (III).The force-velocity (F-v) and power-velocity (P-v) relationships were determined on the basis of results of exercises performed on a Monark 874 E cycloergometer connected to a PC, using the MCE 4.0 software package. After adjusting the ergometer saddle and handlebars each subject performed the tests in a stationary position, without lifting off the saddle, with his feet strapped onto the pedals. Each player performed five 10-second maximal cycloergometer tests with increas- ABSTRACTPurpose. The aim of the study was to follow the changes of maximal power output and power-velocity relationship in male volleyball players during an annual training cycle. Basic procedures. The study was conducted on six first-league volleyball players: age 25.0 ± 5.3 years, body height 195.2 ± 7.2 cm and body mass 91.2 ± 14.7 kg. Force-velocity and power-velocity relations were determined from five maximal cycle ergometer exercise tests, 10 s each, with increasing external loads amounting to 2.5, 5.0, 7.5, 10.0 and 12.5% of body weight, respectively. There were 2-min breaks between the tests. Maximal power output was computed from power-velocity curves. Maximal power output and power-velocity relationships were determined before the preparatory period (I), after the first competitive season (II) and after the second competitive season (III). Main findings. Significant increases occurred in the maximal power output from 12.80 ± 0.79 (preparatory period) to ...
