The objectives of this study were to (i) describe soccer training (e.g., volume, types), anthropometry, body composition, and physical fitness and (ii) compute associations between soccer training data and relative changes of anthropometry, body composition, and physical fitness during a soccer season in female elite young athletes. Seasonal training (i.e., day-to-day training volume/types) as ...

OBJECTIVE A study to examine the incidence and characteristics of concussions among Canadian university athletes during 1 full year of football and soccer participation. DESIGN Retrospective survey. PARTICIPANTS Three hundred eighty Canadian university football and 240 Canadian university soccer players reporting to 1999 fall training camp. Of these, 328 football and 201 soccer players retu...

BACKGROUND Improved oxygen uptake improves soccer performance as regards distance covered, involvements with the ball, and number of sprints. Large improvements in oxygen uptake have been shown using interval running. A similar physiological load arising from interval running could be obtained using the soccer ball in training. OBJECTIVES The main aim was to study physiological adaptations to...

BACKGROUND The aerobic capacity of soccer players substantially influences their technical performance and tactical choices. Thus, the assessment of soccer players' aerobic performance should be of interest for soccer coaches in order to evaluate and improve their endurance training sessions. In this study, we present a new test to assess aerobic performance in soccer by means of a specific dri...

The present systematic review and meta-analysis aimed to assess the perturbations in hormonal and psychological homeostasis in response to soccer match-play. These perturbations were explored according to match outcome (i.e., win versus loss), gender, type of contest (i.e., competitive versus non-competitive fixtures) and competitive level (i.e., novice versus high-level). The review was conduc...

conclusions independent of their level, professional soccer players, need 48 hours to recover after an official match. professionals gain more fatigue than young players after a match, but recover as fast. thus, they recover more efficiently especially due to a better physical condition and fitness training. it is expected that the results showed in the study help elite soccer and fitness coach...

A bstract. T he periodic behavior of a particu lar class of dynamical sys tems , the cellular automata (CA) , is studied . A lar ge class of CAs is defined , (containing both addit ive and nonadditive CAs) in terms of the sensi tivity of t he local rule on which the CA is based . For this class , the set of configurations which ente r a cycle afte r a finit e number of it erat ions is complete ...

The evolution of referees' physical fitness has been studied over one or several seasons, however, the variation of the physical performance between the end of the competitive season (T1) and the start of the following pre-season (T2) has not been ascertained. Therefore, the aim of this study was to analyze the effects of the transition period on physical performance variables (i.e. linear stra...
