“…In the 2-km time trial, both PJT groups improved, with ES values of 0.54 and 0.51 for the Plyo-7 and Plyo-10 groups, respectively (Table 2). Increases in time trial endurance have been previously reported in youths after PJT (5,44), and the results of the current study may be partially related to improved running economy owing to improvements in neuromuscular variables such as reactive strength index (6). In a recent scoping review of 242 articles on PJT (36), only 3 studies incorporated a description of female subjects' maturation status, with none comparing the response between maturity groups.…”

Romero, C, Ramirez-Campillo, R, Alvarez, C, Moran, J, Slimani, M, Gonzalez, J, and Banzer, WE. Effects of maturation on physical fitness adaptations to plyometric jump training in youth females. J Strength Cond Res 35(10): 2870–2877, 2021—The aim of this study was to compare the effects of maturation on physical fitness adaptations to plyometric jump training (PJT) in youth females. Jumping, sprinting, change of direction speed, endurance, and maximal strength were measured pre-post 6 weeks of PJT in 7th- and 10th-grade subjects. In the seventh grade, subjects formed a PJT group (Plyo-7, n = 10; age, 12.7 ± 0.6 years; breast maturation stages IV [n = 2], III [n = 7], and II [n = 1]) and an active control group (Con-7, n = 9; age, 12.8 ± 0.6 years; breast maturation stages IV [n = 2], III [n = 6], and II [n = 1]). In the 10th grade, subjects conformed a PJT group (Plyo-10, n = 9; age, 16.3 ± 0.5 years; breast maturation stages V [n = 5] and IV [n = 4]) and an active control group (Con-10, n = 9; age, 16.2 ± 0.5 years; breast maturation stages V [n = 5] and IV [n = 4]). Magnitude-based inferences were used for data analysis, with effect sizes (ESs) interpreted as <0.2 = trivial; 0.2–0.6 = small; 0.6–1.2 = moderate; 1.2–2.0 = large; and 2.0–4.0 = very large. The Plyo-7 and Plyo-10 showed meaningful improvements in all physical fitness measures (ES = 0.21–2.22), while Con-7 and Con-10 showed only trivial changes. The Plyo-7 and Plyo-10 showed meaningful (ES = 0.16–2.22) greater improvements in all physical fitness measures when compared with their control counterparts. The Plyo-10 showed meaningful greater improvements in 20-m sprint, 2-km running time trial, maximal strength, squat jump, and drop jump from 20 cm (ES = 0.21–0.42) when compared with Plyo-7. In conclusion, PJT is effective in improving physical fitness in younger and older female youths. However, greater adaptations were observed in more mature subjects.

“…Similarly, in another meta-analysis Ramirez-Campillo, Andrade, et al ( 2021) reported moderate (ES = 0.88) improvement in time-trial performance in endurance runners after plyometric jump training. Indeed, such training may improve anaerobic performance qualities (Assunção et al, 2018) related to endurance performance. Moreover, the neuromuscular adaptations may have improved rate of force development, motor unit recruitment, and increased tendon stiffness (Markovic & Mikulic, 2010), thus positively influencing the running economy of soccer players (Balsalobre-Fernández et al, 2016;Ramirez-Campillo, Andrade, et al, 2021).…”

This systematic review and meta-analysis aimed to assess the effects of complex contrast training (CT) on aero- bic endurance, maximal strength, and repeated sprint ability (RSA) in soccer players. After an electronic search, nine peer-reviewed articles were considered, including soccer players from junior to professional-level (age 14 – 23 years). One study was conducted during the pre-season, seven studies during the in-season, and one study during the off-season period of a competitive schedule. The studies included were of moderate to high meth- odological quality (PEDro scale) and incorporated CT with soccer practice. Large significant improvements (ES = 1.30; 95% CI = 0.61 – 2.00; p < 0.001; I2 = 80.6%) for maximal strength, and small non-significant improve- ments for aerobic endurance (ES = 0.33; 95% CI = -0.19 – 0.85; p = 0.209; I2 = 0.0%) and RSA (ES = 0.32; 95% CI = -0.12 – 0.75; p = 0.156; I2 = 0.0%) were noted for CT groups when compared to active or specific-active control groups. Therefore, supplementing regular soccer training with CT induces adaptations to improve maximal strength. CT may be implemented during the pre-season and in-season to induce adaptations similar to tradi- tional strength training (e.g., maximal strength gains), although alternative training strategies may be needed to further improve aerobic endurance and RSA. The use of CT may be applicable during different periods of the season to achieve certain goals, e.g., pre- and in-season for maximal strength development, and off-season to attenuate the decline of strength or power.

“…HIMT also can involves a large component of plyometric jumps, which might improve physical performance in young people and are safe over short term (De Freitas Guina Fachina et al, 2017;Assunção et al, 2018;Ramirez-Campillo et al, 2019a,b;Vera-Assaoka et al, 2020). However, it is important to remember that overuse injuries and tendinopathies are frequent in young athletes (Le Gall et al, 2006;Johnson et al, 2020), which might be due to an imbalance between muscle and tendon adaptation (Mersmann et al, 2014(Mersmann et al, , 2016(Mersmann et al, , 2017.…”
