The Effect of an In-Season 8-Week Plyometric Training Programme Followed By a Detraining Period on Explosive Skills in Competitive Junior Soccer Players

Abstract

The aim of this study was to examine the effect of an eight-week plyometric training and resistance programme, on different motor abilities, kicking speeds, and individual techniques in competitive junior soccer players. A training programme was applied for eight weeks and was composed of countermovement jump, countermovement onto a box, sprints, and sprints with change of direction. The players were evaluated in three moments: before the start of the training programme, after the application of the training programme, and after four weeks of detraining. The applied tests were: countermovement jump, speed dribbling, 30-meter sprint, kicking speed, and a Yo-Yo recovery intermittent recovery test Level 2 (Yo-Yo IE2). The results showed statistically significant differences (p<0.05) in sprint performance, countermovement jump, Yo-yo IE 2, and speed dribbling. The maximum velocity of the ball did not present statistically significant differences (p > 0.05). In addition, these results indicate that general performance may not be sensitive to four weeks of detraining in the trained soccer players. These results demonstrate that the combination of soccer drills and specific power training with no additional training time in-season optimizes some general and soccer-specific performance.

“…If we take into account the dynamics of its growth, we can say with certainty that it will soon be included in one of the three most prestigious categories within the "Web of Science" database (SCI, SSCI or SCIE) and will receive an impact factor. Very high quality scientific papers by eminent authors, which were published in the first [34, 35, 36, 37, 38, 39, 40, 41, 42, 43, ] and the second edition of the eight volume [44,45,46,47,48,49,50,51,52,53], and also in the first edition of the ninth volume [54,55,56,57,58,59,60,61,62,63,64]are guarantee that it will happen. At the very end, the youngest, but still a journal that has made notable progress is the "Journal of Anthropology of Sport and Physical Education".…”

Physical performance changes during circuit training and detraining in U15 soccer players

“…To our knowledge, no study analysed the effects of detraining on CODS in young soccer players, which means that future research is warranted. In a study that investigated the effects of an in-season plyometric training, followed by detraining on physical performance in junior male soccer players (~17 years), the authors observed that the ability to change of direction with ball during a dribbling speed test was not affected by a 4-week detraining period (Branquinho et al, 2020). Although these results may indicate that this quality can be preserved after the detraining, the findings are specific to the dribbling speed test.…”
