Effects of Bout Duration on Load, Sprint, and Jump Ability During a One-on-one Transition Task

Abstract

This study examined the training load on professional soccer players during transition games performed with different bout durations, and their effects on speed and jump tests. Fourteen young soccer players played a transition game with different bout durations: 15 (TG15), 30 (TG30) and 60 (TG60) seconds. Total distance covered (DC), accelerations and decelerations above 1.0 and 2.5 m·s-2, rate of perceived exertion (RPE), maximal heart rate (HRmax) and above 90% (HR>90), distance covered between 18.0-20.9 km·h-1 (DC 18.0-20.9 km·h-1), 21.0-23.9 km·h-1 (DC 21.0-23.9 km·h-1), above 24.0 km·h-1 (DC >24.0 km·h-1), peak speed, sprint profile, sprint and countermovement jump tests were recorded. TG15 obtained greater DC, DC >21.0 km·h-1, Player load, Acc >2.5 m·s-2 than TG30 and TG60 (p < 0.01) and Acc <2.5 m·s<sup>-2</sup>, Dec >2.5 m·s<sup>-2</sup> than TG60 (p < 0.01). TG30 showed more HR<sub>>90</sub> and RPE (p < 0.01) than TG15, and DC, DC >18.0 km·h<sup>-1</sup>, Player load, Acc >2.5 m·s<sup>-2</sup>, Dec >2.5 m·s<sup>-2</sup>, HR<sub>>90</sub> and RPE than TG60 (p < 0.01 and <0.05). Transition games showed lower sprint and jump results after the intervention (p < 0.01). Bout duration has been configured as an important constraint that influences the transition games and the performance of soccer players.

Influence of the Number of Players on the Load of Soccer Players During Transition Games

“…In relation to the test's outcomes, the soccer players response was varied depending on the TG. Contrary to previous reports in the literature, which indicated that running and jump performance were reduced after 15, 30 and 60 s of TGs [9], TG 2vs1 showed no changes in these abilities, TG 3vs2 showed improvement in CMJ, and TG 1vs1 showed a lower performance for S 15 and CMJ. The greater RPE recorded during TG 1vs1 could have led to the decrease in test performance after the intervention.…”

“…The greater RPE recorded during TG 1vs1 could have led to the decrease in test performance after the intervention. The reported RPE values may also explain the differences between these data and the existing literature, since a higher level of perceived fatigue was reached in the previous published work (9 vs 6-7 UA) [9]. Also, the short execution times of the TGs used in the present study (<15 s) may have maximized high-energy phosphates as the primary energy source, with This article is protected by copyright.…”

“…Before and after the TGs, the assessment of the physical performance of the soccer players in the jump and sprint tests was conducted. The protocol used has been described in a previous study [9]. Before all measures, participants carried out a 15-minute standardized warm-up consisting of 5 minutes of low-intensity running, 5 minutes of mobility and active stretching, and two sets of incremental 30-m running sprints.…”

“…Recently, the literature has focused on transition games (TGs) as a specific tool to simulate these high-intensity actions [9][10][11]. TGs are training tasks in which players continuously engage in counter-attack situations, using fast attacking and defensive transitions [10].…”

“…sided-games, they reproduce specific aspects of matches, achieving a more homogeneous workload among players [9,11,13].…”
