Current soccer scientific literature is scarce with regard to examining the technical performance of substitute players. Purpose: This study aimed to analyze the physical and technical performance of substitute players versus those who completed the entire match or were replaced and also examine the performance of substitutes across different…

Purpose: The aim of the study was to verify the agreement between preplanned and executed pacing during a 3-km race and determine whether adjustments are mediated by the rating of perceived exertion (RPE). Method: Thirteen young runners (eight males and five females, 17.5 ± 2.1 and 17.0 ± 1.6 years old, respectively) with national and…

Objectives: While sleep research in athletes is extensive, no research has investigated sleep in sports officials during a competitive season. This study explored the (a) self-reported quantity and quality of sleep obtained by sports officials according to the time of competition (day or evening) and (b) impact of reduced sleep on perceived…

Purpose: The purpose of this study was to examine the physical match profiles of professional soccer players using 3 and 5 min fixed and rolling averages as well as fixed 1 min averages, with considerations to training prescription. Methods: Twenty-nine professional U23 soccer outfield players competed across 17 competitive matches during the…

Identification of the exercise volume and intensity of basketball referees, across competitive match types based on competition sex and level, would assist in developing appropriate training regimes. Purpose: The aims of this study were to quantify and compare the exercise volume and intensity encountered by semiprofessional basketball referees…

Purpose: Simulated competition as a training tool has a relevant role in enhancement of exercise intensity, motivation and physical enjoyment. Including a competitive component into the agility training could represent another way to improve agility performance significantly more. The aim of this study was to assess the effect of agility training…

Purpose: The aim of this study was to provide an in-depth analysis of the prevalence and consequences of within-sport specialization in track and field in the United Kingdom. Method: The competition histories of top 100 ranked athletes from four representative events (100 m, 800 m, long jump, and shot put) were recorded from a…

Purpose: The purpose of this study was to determine the influence of eight different small-sided games (SSG) on physical, technical, and decision-making demands of training environments in U14 field hockey. Methods: A total of 13 participants played eight different training games consisting of two 7.5-minute halves, where number of players (three…

Purpose: Peak and maximal oxygen uptake (VO[subscript 2peak] and VO[subscript 2max], respectively) are used in assessing aerobic power. For swimmers with physical impairments, it is unclear whether the physiological variables obtained in 200-m and Nx200-m tests are similar. The objective of this study is to assess the validity of VO[subscript…

Purpose: The aim of this study was to analyze the relationship between physical preparation, training sessions (TS) and friendly matches' (FM) demands, and playing status during European Championship (EC). Method: Twelve under-16 (U-16) basketball players performed physical (jumping, agility, aerobic fitness, and lower limb asymmetry index [ASI])…

Purpose: The present study aimed to investigate associations between hormonal profile (cortisol and testosterone) and the psychobiological aspects of Paralympic athletes during a competitive season. Method: Male Brazilian Paralympic swimmers (n=11) were evaluated in three Training Camps (TC) during the cycle of training for the Paralympic Games…

Purpose: To evaluate the relationship between years of collegiate playing experience and success of NCAA Division I volleyball programs. Methods: Data were gathered from the 2010-2015 seasons for each volleyball program in the "power five" conferences. Players that were involved in at least 66% of the sets were selected for analysis.…

Purpose: In team sports, players have to manage personal interests and group goals, emphasizing intricacies between personal and social identities. The focus of this article was to examine the effect of identity mechanisms on appraisal processes, based on the following research question: Does the level of self-abstraction (low [personal identity]…

Purpose: This research investigated whether Zimmerman's model of self-regulated learning could be transferred into a competitive setting. We also investigated whether a feedforward self-modeling video could influence one's use of self-regulation and as such be an effective self-regulatory intervention. Methods: Nine competitive gymnasts took part…

Match activity demands of basketball players have been well reported but little exists in terms of quantifying the demands encountered by referees during match-play. Potential differences between referees and players may identify different fitness capacities and subsequent need for different training regimes. Purpose: The aims of this brief report…
