Mixed Training Methods: Effects of Combining Resisted Sprints or Plyometrics with Optimum Power Loads on Sprint and Agility Performance in Professional Soccer Players

Abstract

The aim of this study was to compare the effects of two different mixed training programs (optimum power load [OPL] + resisted sprints [RS] and OPL + vertical/horizontal plyometrics [PL]) on neuromuscular performance of elite soccer players during a short-term training preseason. Eighteen male professional soccer players took part in this study. The athletes were pair-matched in two training groups: OPL + RS and OPL + PL. Unloaded and resisted sprinting speeds at 5-, 10-, 20-, and 30-m, change of direction (COD) speed, and performance in the squat jump (SJ), countermovement jump (CMJ), and horizontal jump (HJ) were assessed pre- and post- a 5-week training period. Magnitude based inference with the effect sizes were used for data analysis. A possible increase in the SJ and CMJ heights and a likely increase in the HJ distance were observed in the OPL + PL group. Meaningful improvements were observed in the COD speed test for both training groups comparing pre- and post-measures. In both unloaded and resisted sprints, meaningful decreases were observed in the sprinting times for all distances tested. This study shows that a mixed training approach which comprises exercises and workloads able to produce positive adaptations in different phases of sprinting can be a very effective strategy in professional soccer players. Moreover, the possibility of combining optimum power loads with resisted sprints and plyometrics emerges as a novel and suitable option for coaches and sport scientists, due to the applicability and efficiency of this strength-power training approach.

Optimum Power Loads for Elite Boxers: Case Study with the Brazilian National Olympic Team

“…Conversely, after the control period, we did not detect any worthwhile increases in the assessed variables. These results are similar to those previously described in team sport athletes [ 2 , 25 , 26 ]. To our knowledge, this is the first study to report these benefits in Olympic athletes from the individual sport of boxing.…”

Vertically and horizontally directed muscle power exercises: Relationships with top-level sprint performance

“…On the other hand, Kale et al [ 15 ] demonstrated that, among several variables collected in vertical and horizontal jumps, the drop jump height is the best indicator of maximum velocity attained by an elite sprinter throughout a 100-m dash race. Similar results were obtained in a series of recent investigations executed with sprinters and team sport athletes, confirming that the direction of the resistance force vector relative to the body is determinant in mediating adaptations to speed qualities [ 4 , 16 , 17 ]. However, although some of these studies have been carried out using vertical exercises performed at the optimum power zones (i.e., using loads capable of maximizing power output) [ 4 , 16 , 18 ], there is a lack of research on this topic with horizontally-directed exercises (e.g., hip-thrust).…”

“…this manipulation will impact on the number of times that players should apply force horizontally into the ground to overcome the inertia and move their bodies forward as rapidly as possible throughout a given workout. recent studies have shown that the development of training strategies (e.g., horizontally-directed exercises) which prioritize the application of force in the horizontal direction are paramount to significantly improve sprinting speed [45][46][47]. the present study found that the 40-m shuttle-sprint speed was very likely (99% chances of a real effect) improved after SrIt-3, but unclear changes (64/28/08%; ES = 0.33) were noticed following the SrIt-1 training model.…”
