Summary: This study examined differences in intense physical performance during competitive match-play between one-match and two-match microcycles. Results showed that during periods of fixture congestion, there were significantly reduced average values for total distance and high-speed running in certain time periods, but the average values for high-speed running towards the end of the match (75-90 min) showed a decrease. However, there may be an opposite trend in the 60-75 min period.

Summary: The present study evaluated tactical and physical performance during official matches of a women's soccer league and found correlations between both dimensions in 15-minute periods. Eight matches from the 2020-2021 season of the Women's Second Division in Spain were analyzed. Tactical variables (Width, Length, Height, and Surface Area) and physical variables (Total Distance Covered, Total Distance Covered in High-Speed Running, and Total Distance Covered in Sprint) were recorded. The study found no differences in the tactical dimension between periods, a decrease in total distance and high-speed running at the end of the match, and positive correlations among some variables in the tactical and physical dimension at different periods. Connecting the tactical and physical dimension would enhance the understanding of player and team performance during competition.

Summary: The purpose of this study was to investigate whether tactical formation affects the physical and technical match performance of professional soccer players in the first German Bundesliga. The study found that the degree to which tactical formation affects match performance is position dependent. Center backs, full backs, and wide midfielders showed significant differences in physical and technical performance between different tactical formations, while central midfielders and forwards only showed small differences. These findings can help coaches plan their training and anticipate changes in performance based on the chosen formation.

Summary: This study analyzed the effects of red and yellow cards on the scoring rate in elite soccer. The results showed that after a player is sent off, the scoring rate of the penalized team decreases significantly, while the opponent's scoring rate increases. The impact of a red card is more or less maintained over time intervals when the player belongs to the Away team, but fades over time when the affected team is stronger. The relative difference in scoring rates is also influenced by the goal difference and the difference in booked players.

Summary: One of the most common task constraints in designing small-sided games (SSGs) is to manipulate the pitch size to change the relative area per player. This review aimed to compare the effects of smaller and larger pitch sizes on soccer players' physiological, physical, technical, and tactical responses during SSGs. The results showed that compared to smaller pitches, SSGs played on larger pitches resulted in higher heart rate, perceived exertion, total distance, high-speed running, stretch index, and surface area.

Summary: The objective of this study was to analyze the clinical and microbiological benefits of adding antimicrobial photodynamic therapy (aPDT) to scaling and root planing (SRP) in smokers with periodontitis. Eight randomized clinical trials (RCTs) were included. The results showed that aPDT, as an adjuvant to SRP, improved the reduction of probing depth (PD) and clinical attachment level (CAL) more effectively than only SRP. However, aPDT did not demonstrate efficacy in reducing the microbial species associated with periodontitis. More RCTs with standardized protocols and longer follow-up times are needed to provide further evidence on aPDT adjunctive to SRP in smokers with periodontitis.
