“…Consequently, match analysis studies can provide useful information for coaches, who need significant, relevant, and easily gathered feedback to be successfully applied in training and competitive matches ( Hughes and Franks, 2004 ; Wright et al, 2013 ). Today, technologically advanced systems are commonly used for data gathering ( Castellano et al, 2014 ) based on the state-of-the-art algorithms along with video-recording technology to supply data on the physical (motion analysis) and technical and tactical (notational analysis) performance of soccer players ( Bradley et al, 2013 ; Konefał et al, 2019a ) with regard to their playing positions ( Andrzejewski et al, 2018 ) and contextual variables ( Chmura et al, 2017b ; Gai et al, 2019 ; Oliva-Lozano et al, 2020 ).…”

This study aimed to examine whether the physical and technical activities of soccer players and match locations can be associated with higher or lower odds of winning matches whose outcome can be described as “close.” The study comprised 7972 individual observations of German Bundesliga players during the 2014/2015 ( n = 2794), 2015/2016 ( n = 2494), and 2016/2017 ( n = 2684) seasons. A selection of “close matches” was made, which were defined as those in which the difference in numbers of scored goals was ≤1. Players’ five pitch positions were considered: central defenders, fullbacks, central midfielders, wide midfielders, and forwards. Data on 12 physical and 10 technical activities performed by players during matches as well as on match location were retrieved from the Impire AG (Germany) match analysis system. The study results show that the odds of winning at home are different for each playing position: from 41.99% for wide midfielders to 91.34% for central midfielders. Another conclusion was that one of the key components of the predictive model for forwards is the percentage of overall distance covered at speeds >24 km/h (7.99%), which is a variable with an increasing trend. The proposed model predicts that each 1% increase in this variable will theoretically be associated with a 4.08% raise of the odds of winning in further seasons. The presented statistical model may be used by trainers to identify players’ physical and technical activities and contextual variables that may significantly affect the match outcome. In addition, it can help to determine the individual training load related to the player’s position on the pitch.

“…Research to date has indicated that the more difficult biometeorological conditions during a competition are, the harder it is to succeed (Mohr et al 2012, Chmura et al 2017a). The present study confirms these reports but also makes a novel observation that when matches take place in conditions of no thermal stress (NTS), the biometeorological conditions at training centres also prove to be significant for the match outcome.…”

“…Subsequent analyses showed that the longest recorded mean distance (10.5 km) was covered by players in an air temperature below 22°C and relative humidity below 60%, while the shortest (9.8 km) was covered in the same air temperature range, but with relative humidity above 60%. Significant differences in the number of sprints performed by players were found between the air temperature ranges below 22°C (41 performed sprints) and above 28°C (31), but only at the relative humidity below 60% (Chmura et al 2017a). What is more, Nassis et al (2015) found that while the numbers of passes did not differ, the pass accuracy was higher under high, rather than low, environmental stress conditions.…”

The influence of thermal stress on the physical and technical activities of soccer players: lessons from the 2018 FIFA World Cup in Russia

The present study attempts to assess changes in soccer players' physical and technical activity profiles due to thermal stress, measured with the Universal Thermal Climate Index (UTCI), in training centres and during matches of the 2018 FIFA World Cup in Russia. The study also verifies the theoretical models of soccer players' physiological parameters. The study sample consisted of 945 observations of 340 players of national teams taking part in the World Cup in Russia. The measured variables included physical activities: total distance covered, distances covered with an intensity of 20-25 km/h, number of sprints; technical activities: number of shots, number of passes, pass accuracy and physiological indicators: evaporative water loss and heart rate. In addition, the final ranking places of each national team were also used in the study. The UTCI was calculated based on meteorological data recorded at training centres and during matches. The UTCI records were then classified into two ranges: NTS-no thermal stress (UTCI 9-26°C) and TS-thermal stress (UTCI > 26°C). Climatic conditions at soccer training centres assessed as involving "no thermal stress" are found to be more beneficial for increasing the total distance covered and the number of sprints performed by players during a match. The theoretical models for determining soccer players' physiological parameters used in the study reduce the players' heart rate effort and evaporative water loss, which is in line with findings in studies by other authors. The climatic conditions at soccer training centres and during tournament matches should be taken into account in planning preparations for future World Cup tournaments, especially those in hotter countries.

“…Scientific publications describe measurements of indoor air quality. They were conducted in didactic rooms (Asif et al 2018;Chmura et al 2017;Hwang et al 2017;Kviesis et al 2017;Marć et al 2018;Śmiełowska et al 2017). In most publications, the evaluation of the results was based on a Fig.…”

The indoor thermal condition tests were conducted as real and declared by the respondents. The tests were carried out in the laboratory room in Bialystok. The object is a detached, two-storey building with a cellar. The tests were carried out from February to May 2015. In 1 week, on average, ten measurement series were carried out. During one experiment series, there were between 10 and 15 students present in the room. The aim of the publication is to analyze the results of declared perceived temperature tests in the room depending on the gender, the season and indoor and outdoor temperature conditions. On the basis of statistical analysis of the test results, it was found that in the analyzed age group, the perceived temperature declared in the room is not affected by the respondent's gender. The conclusion is that the temperature sensations of young (and probably healthy) people who do not do physical work are similar, regardless of gender. Differences between the average perceived temperature in the room, declared by all respondents in winter and declared in spring are statistically significant. The indoor perceived temperature declared in the winter is almost constant and does not depend on the temperature of the perceived temperature of outdoor air.
