The study evaluates the effect of soccer match induced fatigue on the neuromuscular performance. Prior to, during the break period between the 1st and 2nd part of the game and after the game, parameters of agility, explosive power of lower limbs, static and dynamic balance, speed of step initiation and the soccer kick were evaluated in a group of 10 soccer players. Reaction time in the agility ...

This paper presents a hybrid method for learning a dynamic strategy for a robot soccer team. In this method, an imitation learning scheme based on observed robot soccer games is used as a seed for an experience-guided learning scheme based on reinforcement learning. A lack in the application of classic reinforcement learning to the robot soccer problem is the high number of states to be analyze...

BACKGROUND Static stretching (SS) is a recovery intervention used for the reduction of muscle soreness postexercise. The effects of SS on elite young footballers have received little attention, and therefore the aim of this study was to assess the effects of SS on muscle recovery following competitive soccer matches in elite young footballers. METHODS Ten male participants (16±1 years) were r...

The purpose of this study was to verify the effects of a carbohydrate-electrolyte drink on soccer performance. Twenty soccer players volunteered to participate in the study. Players were allocated to two assigned trials according to their positional roles in the team: CHO group (ingesting a 6% carbohydrate-electrolyte solution at regular 15 minutes intervals) and NCHO (ingesting no fluid) durin...

Background: Successful performance in soccer is associated with multiple factors such as physical, technical and perceptual-cognitive performance. In contrast to physical fatigue, nowadays one of the most popular affecting mental especially soccer. Objectives: This systematic review aims clarify impact fatigue intervention on psychophysiological responses cognitive Methods: A literature was con...

This review describes when fatigue may develop during soccer games and the potential physiological mechanisms that cause fatigue in soccer. According to time-motion analyses and performance measures during match-play, fatigue or reduced performance seems to occur at three different stages in the game: (1) after short-term intense periods in both halves; (2) in the initial phase of the second ha...

We conducted three experiments to examine the relationships between emotions and subcomponents of performance. Experiment 1 revealed that anger was associated with enhanced gross muscular peak force performance but that happiness did not influence grammatical reasoning performance. Following Lazarus (1991, 2000a), we examined hope rather than happiness in Experiment 2. As hypothesized, hope yie...

Cross-sectional studies revealed that inclusion of unstable elements in core-strengthening exercises produced increases in trunk muscle activity and thus potential extra stimuli to induce more pronounced performance enhancements in youth athletes. Thus, the purpose of the study was to investigate changes in neuromuscular and athletic performance following core strength training performed on uns...

The purpose of this study was to investigate diurnal variation in some specific skills performance and some physical fitness and physiological factors in soccer players. Twelve male soccer players (mean±SD; age 22.6±3 years; height 1.76±4.4 m; body mass 66.5±4.6 kg) participated in the study. Subjects performed some specific soccer skills and some physical fitness factors in one day. One test w...

Distributed play-based approaches have been proposed as an effective means of switching strategies during the course of timed, zero-sum games, such as robot soccer. In this paper, we empirically show that different plays have a significant effect on opponent performance in real robot soccer games. We also consider the problem of distributed play recognition: classifying the strategy being playe...
