These findings indicate that high-intensity actions and markers of acceleration and deceleration capacity are reduced in the last 15 minutes of the normal duration of match-play. Such information can be used to increase the specificity of training programs designed for soccer players while also giving further insight in to the effects of 90 minutes of soccer-specific exercise.
Interventions that seek to maintain the acceleration and deceleration capacity of players throughout the full duration of a soccer match warrant investigation.

Don't just dig out your boot bag the day before training is due to start and polish your boots Map out your pre-season fitness blueprint for you and your players. You don't have to be on a football pitch to start your pre-season — players and coaches alike can be a bit creative at the beach and set themselves some targets for the holidays.
So put sunbathing on hold get yourself in shape for the coming season! A warm-up that will teach your players practise dribbling the ball with two feet and help them to learn how to change direction quickly MORE. This session sharpens an array of soccer skills at the beginning of a season when players need to get their bodies back into balance and refresh their technique on the ball.
Nonetheless, importantly, they appear to be less efficient at changing direction, which may be related to their reduced ability to deal with greater entry and exit velocities [ 16 , 20 ], or counterbalance the associated mechanical consequences i. This study is inherently limited by its cross-sectional design that does not allow for causal inferences and by the absence of a control group.

In addition, we did not implement any type of biomechanical analysis e. Nevertheless, this is the first study to show this problematic association i. These findings may help coaches and researchers to create better and more effective training strategies to improve COD performance in this respective population. Professional soccer players with higher maximum acceleration rates tend to perform better in loaded and unloaded jumps and be faster in linear and multidirectional speed tests.
On the other hand, as observed in diverse team sport athletes, they also present higher COD deficits. At the present time we cannot confirm if this paradoxical phenomenon is more related to the mechanical consequences of being faster i. Additional studies should be conducted to examine whether more mixed training approaches e. Browse Subject Areas?

Abstract The purpose of this study was to examine the selective influences of the maximum acceleration capability on change of direction COD speed, COD deficit, linear sprint speed, sprint momentum, and loaded and unloaded vertical jump performances in forty-nine male professional soccer players Data Availability: All relevant data are within the manuscript. Funding: The authors received no specific funding for this work. Introduction Modern soccer can be characterized by a progressive and substantial increase in game speed [ 1 — 3 ].
Materials and methods Study design This was a cross-sectional study, which analyzed the selective influences of the maximum acceleration ability on a series of speed-power related tests.
Participants Forty-nine male professional soccer players Sprinting and acceleration abilities Prior to the execution of the speed tests, four pairs of photocells Smart Speed, Fusion Equipment, AUS were positioned at distances of 0-, 5-, , and m along the course. Download: PPT. Statistical analysis The normality of the data was checked using the Shapiro-Wilk test.
