Abstract

The topic of this study has been the examination and comparison of the competitive balance of the Spanish and the English first leagues of soccer, called La Liga Santander and Barclays Premier League. The basis for the research project has been provided by a database of sixteen hundred elements, containing the data of the two leagues starting from the 2014/2015 season up to the 2017/2018 season. When choosing the time period for the study, we intended to avoid having to deal with the impact of Covid-19, which is why we picked exactly these competition seasons. We have primarily used statistical indicators. In the case of sports-related data, our inquiries have included the following: comparing and averaging the winning percentages per season, furthermore, the winning percentages of championship seasons, the distribution of goals scored and conceded and, finally, the calculation of the Herfindahl-Hirschman Index. Although there is one aspect of investigation according to which the competition balance of La Liga is closer to the optimal, the dispersion of winning percentages and the indicator of the goals conceded as well as the HHI index show that the Premier League is the more balanced competition of the two.

The aim of this study was to assess the early electrocardiogram (ECG) changes induced by physical training in preadolescent elite footballers. This study included 94 preadolescent highly trained male footballers (FG) competing in Serbian Football League (minimum of 7 training hours/week) and 47 age-matched healthy male controls (less than 2 training hours/week) (CG). They were screened by ECG and echocardiography at a tertiary referral cardio center. Sokolow–Lyon index was used as a voltage electrocardiographic criterion for left ventricular hypertrophy diagnosis. Characteristic ECG intervals and voltage were compared and reference range was given for preadolescent footballers. Highly significant differences between FG and CG were registered in all ECG parameters: P-wave voltage (p < 0.001), S-wave (V1 or V2 lead) voltage (p < 0.001), R-wave (V5 and V6 lead) voltage (p < 0.001), ECG sum of S V1–2 + R V5–6 (p < 0.001), T-wave voltage (p < 0.001), QRS complex duration (p < 0.001), T-wave duration (p < 0.001), QTc interval duration (p < 0.001), and R/T ratio (p < 0.001). No differences were found in PQ interval duration between these two groups (p > 0.05). During 6-year follow-up period, there was no adverse cardiac event in these footballers. None of them expressed pathological ECG changes. Benign ECG changes are presented in the early stage of athlete’s heart remodeling, but they are not related to pathological ECG changes and they should be regarded as ECG pattern of LV remodeling.
