High Speed Running and Sprinting Profiles of Elite Soccer Players

Abstract

Introduction

Studies continue to investigate the physical and technical performances of elite soccer players during official games across congested periods (Bradley et al., 2009; Rampinini et al., 2007; Rey et al., 2010) in accordance with positional roles (Bradley et al., 2009; Di Salvo et al., 2007; Rampinini et al., 2007) or depending on the match conditions.

In particular, Rampinini et al. (2007) observed that the work rate of professional soccer players was significantly influenced by the activity profile of their opponents. According to their results, the total distance covered and the amount of high-intensity running during matches were higher against ‘better’ opponent teams than against ‘weaker’ opponent teams. Other studies suggest that the poorer the quality of the opponent, the shorter the distance covered by the reference team (Bloomfield, 2005; Lago et al., 2010). These findings suggest that players can increase or decrease their work rate according to both demands of individual matches and the quality of the opposition. Consequently, distances covered by players from top teams could be shorter than those of their opponents: the higher the quality of the teams, the shorter the distance covered by their players.

The opponent level has been considered from different methodological perspectives. For example, teams and players have been categorized as “successful” and “unsuccessful” according to their standings within a particular tournament or classified as “strong” or “weak” based on symmetric division of end-of-season classification (Taylor et al., 2008). Lago et al. (2010) defined the quality of opposition as the differences in the end-of-season ranking between opposing teams. Recently, team performance has been classified using cluster analysis procedures, which improved the classification by using more valid cut-off values.

However, the impact of the quality of the teams on physical performances in soccer is still inconclusive. This may be due to the fact that previous studies have not investigated teams of excellence, i.e., teams that usually win the domestic league and international competitions such as the European Cup or the Intercontinental Cup.

Therefore, the aim of this study was to examine the physical performance of Real Madrid during the 2001-2002 to 2006-2007 seasons (six seasons) and to compare if there were differences between teams depending on their quality. Real Madrid was named as the best club of the 20th century by the International Federation of Football History and Statistics (IFFHS) and won during the explored period 1 European Cup, 1 Intercontinental Cup, 1 European Super Cup, 2 Spanish Leagues and 1 Spanish Super Cup. According to the research framework, it was hypothesized that the players from Real Madrid covered shorter distances in High-Intensity Running and Sprint than players from the opposing team.

Methods

Results

The physical indicators across playing positions for Real Madrid and the opposing team are summarized in Tables 1 and ​and2.2. Players from Real Madrid covered shorter distances (p < 0.05) in HIR than players from the opposing team (Table 1). While ED did not show differences in their physical performance, CD (p < 0.05), CM (p < 0.01), EM (p < 0.01) and F (p > 0.01) from Real Madrid covered shorter distances in HIR than their counterparts (180 v. 192, 257 v. 284, 354 v. 382 and 269 v. 297, respectively).

Similarly, the Real Madrid players covered shorter distances in Sprint (p < 0.05) than players from the opposing team (Table 2). While CD and CM did not show differences in their physical performance, EM (p < 0.05) and F (p > 0.01) Real Madrid players covered shorter distances in Sprint than their counterparts (320 v. 361, 235 v. 306, respectively). However, ED from Real Madrid covered higher distances than their counterparts (374 v. 320, p < 0.05).

Concerning the number of high-speed runs (21.1.-24.0 km/h), CM (p < 0.01; η² = 0.031), EM (p < 0.05; η² = 0.041) and F (p < 0.05; η² = 0.024) from Real Madrid performed less efforts than the opposing team (10.7 v. 21.1, 25.0 v. 28.1 and 19.9 v. 22.0). Additionally, there were no differences for ED and F players (Figure 1).

Finally, ED (p < 0.05; η² = 0.012), CM (p < 0.05; η² = 0.008), EM (p < 0.05; η² = 0.034) and F (p < 0.01; η² = 0.064) from Real Madrid executed a lower number of sprints (<24.0 km/h) than their counterparts from the opposing team (16.1 v. 14.9, 9.1 v. 10.0, 14.8 v. 17.2, 11.7 v. 14.6). Also, no differences were found for CD players (Figure 2).

No differences were revealed in the HIR and Sprint distances performed by players from Real Madrid depending on the quality of the opposition. Similarly, the number on high-intensity runs and sprints did not vary depending on the strength of the opposing team.

Discussion

The main aim of this study was to examine the effects of the quality of the opposition on high-speed running and sprinting performance in elite soccer. Although previous studies have shown that the work rate of professional soccer players was significantly influenced by the activity profile of the opponents (Lago, 2009; Lago and Martin, 2007; Taylor et al., 2008), these findings are still inconclusive given that most of these works were based on small sample sizes or did not examine teams of excellence, i.e., teams that usually win the domestic league and international competitions.

The major finding was that players from Real Madrid covered shorter distances in HIR and Sprint and executed less sprints than players from the opposing team. These findings may be explained by two different reasons. Firstly, it has been demonstrated that soccer players perform significantly less high-intensity activity when winning than when losing or when the score is balanced (Bloomfield et al., 2005; Castellano et al., 2011; Shaw and O’Donoghue, 2004; O’Donoghue and Tenga, 2001). In particular, the Real Madrid team won during the explored period approximately 70% of the total matches played. These results suggest that as the team spent too much time winning and scored first the players did not always use their maximal physical capacity during the match. In fact, given that winning is a comfortable state for a team, it is possible that players assumed a ball retention strategy and slowing down the game resulted in shorter speeds (Bloomfield et al., 2005b; Lago et al., 2010). On the other hand, when losing, players try to reach their maximal activity in order to win or draw the match. However, this scenario is not usually played by the teams of excellence. Other studies have considered match status in relation to the tactical aspects of performance. James et al. (2002) and Lago and Martin (2007) found that teams had longer periods of possession in matches when they were losing than when they were winning. When ahead, teams decreased their possession, suggesting that they preferred to play counter-attacking or direct play (that is, move the ball quickly to within scoring range, often using long passes or long balls downfield). However when behind, they increased their possession, suggesting they preferred to “control” the game by dictating play. In addition, Lago (2009) demonstrated that time spent in possession of the ball in different zones of the pitch (defensive third, middle third, attacking third) was influenced by match status: when teams were losing, possession of the ball was less in the defensive zone and more in the attacking zone than when winning or drawing. Secondly, it has been demonstrated that soccer players modify their activities according to the match conditions and the demands of the play. Probably, players from Real Madrid were more technically and tactically advanced compared to their opponents and this fact allowed them to cover less distance during a match.

Concerning the impact of the quality of opposition on high-speed running and sprinting profiles, no differences were found in the distances covered by players from Real Madrid depending on the strength of the opposing team. These results are not in agreement with other studies. For example, Rampinini et al. (2007) observed that the work rate of professional soccer players was significantly influenced by the activity profile of opponents. The total distance covered and the amount of high-intensity running during matches were higher against ‘better’ opponent teams than against ‘weaker’ opponent teams. Other studies suggest that the poorer the quality of the opponent, the shorter the distance covered by the reference team (Bloomfield, 2005; Lago et al., 2010). The current results may be due to the fact that Real Madrid was able to impose and maintain their pattern of play despite the alteration in variables over the match (e.g., quality of opposition, evolving score) and between matches (e.g., playing at home or away). For example, it has been demostrated that top teams show lower CVs for ball possession per match compared to those who finished lower in the ranking (Lago and Dellal, 2010). Different teams appear to employ different strategies when ahead, level or behind, reflecting the individual styles of coaching and management, the budget, characteristics of the players, team formation and philosophy of play based on the tradition of the club.

One of the most robust findings within the research literature is the relationship between the playing position and match running performance in elite players (Bangsbo, 1994; Di Salvo et al., 2007; Lago et al., 2009; Mohr et al., 2003). Our data supports the well-established finding that external defenders and external midfielders cover greater high-intensity distances than the other playing positions (Carling et al., 2010; Di Salvo et al., 2007).

Additional research using a larger sample of clubs of excellence and across different countries should be performed. Future studies should analyse how performance varies in the same group of players during different periods of the season and from season to season. Moreover, an analysis of the potential variations in physiological responses to match-play across a similar prolonged period of fixture congestion is also warranted. Data on objective markers of fatigue such as plasma creatine kinase concentration, combined with subjective measures of performance, could provide additional information on the individual and team response to fixture congestion. Future studies should include additional situational variables, such as match location or match status. Our findings should be interpreted with caution, as generalisations are difficult in time-motion studies.

In conclusion, players from Real Madrid covered shorter distances in high-speed running and sprint and executed less sprints than players from the opposing team. In addition, no differences were found in the distances covered by players from Real Madrid depending on the strength of the opposing team. These findings may be explained by the fact that Real Madrid was able to impose and maintain their pattern of play despite the alteration in variables over the match. Finally, the performance profiles for playing positions and match running were similar to the ones reported in the literature indicating the standardization of playing roles in soccer.
