Soccer is characterized as an intense intermittent team sport. Heart rate (HR) is used to monitor the players’ training response, as well as to quantify microcycle and mesocycle training intensity during preseason and in-season periods
The coaches’ ability to provide athletes with appropriate affordances (primarily, via the use of task constraints) within game-representative training environments is incumbent for skill learning.
Soccer is a sport that is characterized by the high presence of intermittent efforts during the 90minutes that the match lasts. This has been the conclusion drawn from various research studies that try to clarify the physical and physio-logical requirements of this sport.
Our main finding is consistent with that of previous work whereby elite youth players only attained ~90% of their peak velocity during matches.
The routine use of player-tracking devices to monitor training and competition loads has become standard practice in many elite international and professional team sports(Cummins, Orr, O’Connor, & West, 2013). Technologies such as global positioning system (GPS), local position measurement (LPM) and camera-based visual recognition systems are commonly used to assess competition demands and determine individual “work rates” (Polglaze, Dawson, & Peeling, 2016).
Soccer match play is generally characterised by brief bouts of high-intensity linear and multidirectional activity interspersed with longer recovery periods of lower intensity. Elite level soccer players typically cover 10 to 14 km in total distance per game, where both high-intensity (speeds >14.4 km/h) and very-high-intensity running distance (speeds >19.8 km/h) contribute ~25% and ~8% of the total distance covered, respectively.
In soccer, the final match result in team games, especially association soccer, is determined by multiple factors. One of them is players’ physical preparation which not only affects the level of physical activity of individual players and the whole team, but also the execution of players’ technical-tactical skills and performance efficiency during the game. Physical training has also a significant influence on the effectiveness of analytical and decision-making processes in the player’s brain, especially on making quick and accurate decisions in conditions of incremental fatigue during match-play. It also determines the dynamics of recovery processes during and after sport competition.
