“…Chmura and Nazar 20 verified that the iLan determined in 13 professional soccer players ranged between 13.4 and 14.3km.h -1 before and after six weeks of training. In comparison with our results, it is possible to classify the findings by Chmura and Nazar 20 in the following percentile range: P 30 -P 85 . According to the results of the present study, it can be concluded that the elaboration of percentile tables which can be used as comparison reference for future investigation was possible from the determination of the anthropometric, performance, biochemicl, hematological, hormonal and psychological variables of 82 professional soccer players.…”

“…In order to exemplify the applicability of the percentile tables of the present investigation, we will consider some studies carried out with professional soccer players [7][8][9][10][11][12]20 . Filaire et al 10 verified the responses of the salivary concentrations of cortisol and testosterone, of the psychological variables of the POMS and of the sports performance of 17 French soccer players in four moments of a competitive season.…”

“…Concerning the table 6 of the present study, the expression of the aerobic performance in our athletes through the iLan is justified due to the wide use of the anaerobic threshold to determine the aerobic capacity of professional soccer players 4,6,7,9,20,[22][23][24][25] . Chmura and Nazar 20 verified that the iLan determined in 13 professional soccer players ranged between 13.4 and 14.3km.h -1 before and after six weeks of training.…”

Introduction: The lack of reference values of anthropometric, performance, biochemical, hematological, hormonal and psychological parameters is an important limitation in the investigations with soccer players. Objective: To elaborate percentile tables to be used as comparison reference for further studies. Methods: 82 professional soccer players were evaluated approximately 30 days after the beginning of the main competition played by their teams. On the first day of evaluation, fast blood samples were collected for measurement of hematological parameters (i.e. erythrocytes, hemoglobin, hematocrit, mean corpuscular volume -MCV, mean corpuscular hemoglobin -MCH, mean corpuscular hemoglobin concentration -MCHC, leukocytes, eosinophils, lymphocytes, monocytes and platelets) and of concentrations of adrenaline, cortisol, creatine kinase, creatinine, norepinephrine, testosterone and urea. Subsequently, the soccer players had their anthropometric characteristics and psychological parameters assessed. In addition, the evaluation of the lactic anaerobic system efficiency was performed on a 400-m track. On the second day, both the alactic anaerobic and aerobic system efficiency was measured. Results: The percentile distribution (P 0 , P 15 , P 30 , P 50 , P 70 , P 85 e P 100 ) was used to present the results. Conclusion: The elaboration of the percentile tables can be used as comparison reference for further studies.

“…A goalkeeper who performs activities at a high maximal oxygen uptake, crosses the anaerobic threshold, maintains exercise intensity between the anaerobic threshold and the threshold of psychomotor fatigue, is able to quickly respond to rapidly changing situations in match play, including shots at goal. Activities performed by soccer players, including goalkeepers, between the two thresholds increase reaction speed, accuracy and concentration (Chmura, Wiśnik, 2008;Chmura, Nazar, 2010). However, in match conditions goalkeepers are not often forced to undertake exercises of such intensities.…”

“…During match play a goalkeeper must maintain a high level of mobilization and concentration, quickly react to audiovisual stimuli, make optimal decisions, and display a high level of differentiation between important and unimportant stimuli. All of these capacities can be only reached, if a goalkeeper is able to cross the anaerobic threshold at an exercise intensity close to psychomotor fatigue threshold (PFT) (Chmura, Nazar, Kaciuba-Uściłko, 2007;Chmura, Wiśnik, 2008;Chmura, Nazar, 2010). Research provides numerous data on the total distance covered by goalkeepers.…”

The study aimed to assess the total covered distance during a match, performance volume below and above the anaerobic threshold, as well as characterize physical activities of professional Bundesliga goalkeepers during soccer matches. 34 goalkeepers (606 observations) from all eighteen Bundesliga teams, who played in the 2014/2015 season were considered for the study. The performance of goalkeepers was analyzed with the use of the VIS.TRACK system. The variables measured included: total covered distance [km] in the whole match, the first half, and the second half; distance covered below and above the anaerobic threshold (4 m • s -1 ) [km]; and distance covered in six intensity ranges [km]. The total distance covered by the goalkeepers was 5.48 ±0.56 km. The distance covered by goalkeepers below the anaerobic threshold was 5.28 ±0.52 km, whereas the distance covered above the anaerobic threshold amounted to 0.21 ±0.09 km. The ratio between the goalkeepers' volumes of aerobic and anaerobic performance was 25:1. The total distance covered by goalkeepers in match play and the distances covered by goalkeepers below and above the anaerobic threshold (96.17% and 3.83%, respectively) indicate that during a match the goalkeepers undertake predominantly aerobic exercises.
