In-season training periodization of professional soccer players

Abstract

The aim of this study was to quantify the seasonal perceived respiratory and muscular training loads (i.e., sRPEres-TL and sRPEmus-TL) completed by elite-oriented young professional soccer players. Twenty-four players (20.3 ± 2.0 years) belonging to the same reserve team of a Spanish La Liga club participated in this study. Only the players that were available to train for a whole week with the team and also to play the weekly game were considered: Starters, players that participated in the match for at least 45 min and Non-Starters, players that did not participate or played less than 45 minutes in the match. The competitive period was analysed after the division into 5x6-8 week blocks and 35x1 week microcycles. Data were also analysed with respect to number of days before the immediate match. Weekly TL variation across the in-season blocks was trivial-small for both groups except between Block 2 and Block 3 (ES= moderate). Substantial TL differences (ES= small–very likely) were found between training days, the TL pattern being a progressive increase up to MD-3 followed by a decrease until MD-1. Except for the match, sRPEres-/sRPEmus-TL was very similar between Starters and Non-Starters. In summary, perceived TL across the season displayed limited variation. Coaches periodized training contents to attain the highest weekly TL 72 hours before the match to progressively unload the players between MD-3 and the match day. The data revealed that the TL arising from the weekly game was solely responsible for the observed higher weekly TL of Starters in comparison with Non-Starters.

Relationship of Training Load with High-intensity Running in Professional Soccer Players

“…This is suggestive that drills were focused on using large dimension pitches in an attempt to stimulate HID covered in training during tactical and small-sided games [18]. In all, it should be noted that the variation of TL may be unique to the training organization of the teams, fitness status of players and also the context of the competition schedule [6,9,41]. Most importantly, the changes of TL should be accompanied by a maintenance or improvement in physical performance to be considered successful regarding the periodization strategy employed.…”

In-season internal and external training load quantification of an elite European soccer team

“…Competitive matches have been quantified as the most demanding session (i.e. greatest TL) of the week [7, 24, 34, 36]. For instance, Di Salvo et al [37] reported that CM generally cover more distances compared to other positions during competitive matches.…”

Influencia Del Volumen De Entrenamiento Pliométrico en La Carga Percibida Diferenciada De Futbolistas De Alto Nivel

“…Por ejemplo, Arcos et al (2014) obtuvieron valores inferiores (8-25%), tanto en RPEres CE (1515 ± 134 UA) como en RPEmus CE (1576 ± 147 UA). En otro estudio realizado con jóvenes jugadores de fútbol (Los Arcos et al, 2013), la CE para RPE tanto muscular como respiratorio fue de aproximadamente 900 UA semanales; es decir, entre un 45% y 55% menor a nuestros resultados, si bien en este estudio no se consideró la CE de los partidos. Las diferencias obtenidas en los distintos estudios pueden deberse a múltiples factores como el momento de la temporada (pretemporada o temporada), la duración del entrenamiento (si se incluye o no el tiempo de calentamiento o estiramientos) o la intensidad y planificación de los contenidos.…”

“…Estos sistemas se basan en la monitorización de la frecuencia cardiaca [FC] (Alexiou, y Coutts, 2008;Borresen, y Lambert, 2009;Owen, Wong del, McKenna, y Dellal, 2011) mediante el análisis de variables como la FC media, la FC máxima (García, Ardá, Rial, y Domínguez, 2007;Mallo, y Navarro, 2008), el tiempo transcurrido o metros recorridos por los jugadores en diferentes zonas de intensidad en función de la FC máxima (Casamichana y Castellano, 2010;Gómez, Pallarés, Díaz, y Bradley, 2013;Hill-Haas, Rowsell, Dawson, y Coutts, 2009), u otros métodos de cálculo indirecto como el "Training Impulse" (TRIMP) (Alexiou, y Coutts, 2008;Banister, 1991;Desgorces, Senegas, Garcia, Decker, y Noirez, 2007;Impellizzeri, Rampinini, Coutts, Sassi, y Marcora, 2004;Mallo y Navarro, 2008;Stagno, Thatcher, y Van Someren, 2007), o el método Edwards (Edwards, 1993;Impellizzeri et al, 2004;Los Arcos, Rey, Izcue, y Yanci, 2013).…”

“…Varios autores han validado este método para cuantificar la carga tanto de los entrenamientos como de los partidos de competición (Algrøy, Hetlelid, Seiler, y Pedersen, 2011; Aroso, Rebelo, y Gomes-Pereira, 2004;Impellizzeri et al, 2004;Little, y Williams, 2007;Sampaio et al, 2007). Un gran número de estudios llevados a cabo con futbolistas de diferentes niveles competitivos han mostrado la alta asociación entre la carga percibida y la carga interna cuantificada mediante métodos objetivos, como la concentración de lactato (Coutts, Rampinini, Marcora, Castagna, y Impellizzeri, 2009) y, especialmente, la frecuencia cardiaca (FC) (Gómez, Gómez-Lopez, Lago, y Sampaio, 2012;Kelly y Drust, 2009;Los Arcos et al, 2013;Mallo y Navarro, 2008).…”
