“…Many authors suggested that muscular performance gains after plyometric training are attributed to a neural adaptation located in the nervous system rather than to morphologic changes (4,18,28,33). According to these authors, neuromuscular factors such as increasing the degree of muscular coordination and maximizing the ability to use the muscles' stretch-shortening cycle appear to be more important than changes in fiber size.…”

The aim of the present study was to examine how explosive strength, kicking speed, and body composition are affected by a 12-week plyometric training program in elite female soccer players. The hypothesis was that this program would increase the jumping ability and kicking speed and that these gains could be maintained by means of regular soccer training only. Twenty adult female players were divided into 2 groups: control group (CG, n = 10, age 23.0 +/- 3.2 yr) and plyometric group (PG, n = 10; age 22.8 +/- 2.1 yr). The intervention was carried out during the second part of the competitive season. Both groups performed technical and tactical training exercises and matches together. However, the CG followed the regular soccer physical conditioning program, which was replaced by a plyometric program for PG. Neither CG nor PG performed weight training. Plyometric training took place 3 days a week for 12 weeks including jumps over hurdles, drop jumps (DJ) in stands, or horizontal jumps. Body mass, body composition, countermovement jump height, DJ height, and kicking speed were measured on 4 separate occasions. The PG demonstrated significant increases (p < 0.05) in jumping ability after 6 weeks of training and in kicking speed after 12 weeks. There were no significant time x group interaction effects for body composition. It could be concluded that a 12-week plyometric program can improve explosive strength in female soccer players and that these improvements can be transferred to soccer kick performance in terms of ball speed. However, players need time to transfer these improvements in strength to the specific task. Regular soccer training can maintain the improvements from a plyometric training program for several weeks.

“…This study was conducted to investigate the influence of 10 weeks plyometric training on lower limb power, respectively anaerobic power and reactive power. The ability to jump high and reach maximum height quickly represents a success in volleyball (Potteriger et al, 1999), and explosive strength in the lower extremity is responsible for a good jump (Smith, 1996). The results from the data collected demonstrated that there was an increase in the flight time from pre-test to post-test for all three tests, and a decrease in the contact time period for the two tests; the outcomes were similar for the other test.…”

The aim of the study is to assess the level of specific lower limb power and reactive force in young volleyball players. The 15 female subjects were involved in three pre-tests: 15s jumps, 30s jumps and stiffness test performed according to the Bosco Protocol by using the Optojump Next System. After a 10-week plyometric training programme, a post-test was applied. Compared to the pre-test, the flight times, contact time, height jumps and power revealed significantly higher scores post-test for 15s and 30s jumps test. No significant differences were observed on any variables for the stiffness test. We conclude that the 10-week plyometric training programme increases the anaerobic power in terms of contact time, flight times, height jumps and power jumps.

“…Previous literature has shown that type II Wbres may be more susceptible to damage from eccentric exercise compared to type I Wbres (Jones et al 1986;Asp et al 1998). Aerobic metabolism is primarily responsible for energy provision during 2,000 m rowing; thus, performance is highly dependent on type I muscle Wbres (Hagerman et al 1978), whereas the maximal power tests would be more dependent on recruitment of type II Wbres (Potteiger et al 1999). Therefore, the speciWc muscle function required to carry out the 2,000 m row may have allowed performance to be maintained to a greater extent than that required for the power tests.…”

Does a bout of strength training affect 2,000 m rowing ergometer performance and rowing-specific maximal power 24 h later?

Rowers regularly undertake rowing training within 24 h of performing bouts of strength training; however, the effect of this practice has not been investigated. This study evaluated the impact of a bout of high-intensity strength training on 2,000 m rowing ergometer performance and rowing-specific maximal power. Eight highly trained male club rowers performed baseline measures of five separate, static squat jumps (SSJ) and countermovement jumps (CMJ), maximal rowing ergometer power strokes (PS) and a single 2,000 m rowing ergometer test (2,000 m). Subsequently, participants performed a high-intensity strength training session consisting of various multi-joint barbell exercises. The 2,000 m test was repeated at 24 and 48 h post-ST, in addition SSJ, CMJ and PS tests were performed at these time points and also at 2 h post-ST. Muscle soreness, serum creatine kinase (CK) and lactate dehydrogenase (LDH) were assessed pre-ST and 2, 24 and 48 h post-ST. Following the ST, there were significant elevations in muscle soreness (2 and 24 h, P < 0.01), CK (2, 24 and 48 h, P < 0.01), and LDH (2 h, P < 0.05) in comparison to baseline values. There were significant decrements across all time points for SSJ, CMJ and PS, which ranged between 3 and 10% (P < 0.05). However, 2,000 m performance and related measurements of heart rate and blood lactate were not significantly affected by ST. In summary, a bout of high-intensity strength training resulted in symptoms of muscle damage and decrements in rowing-specific maximal power, but this did not affect 2,000 m rowing ergometer performance in highly trained rowers.
