BACKGROUND: The increase in the number of substitutions allowed in football from three to five has profoundly influenced the game. The impact of the rule change on the FIFA World Cup needs further verification.
METHODS: A total of 2,151 team substitution opportunities and 2,410 substitutions in 384 matches from six FIFA World Cups (2002-2022) were analyzed to assess its impact. One-way ANOVA was used to assess differences in average substitution times among the six FIFA World Cups. Factors affecting the time of substitutions were explored using Generalized Linear Mixed Models.
RESULTS: In each FIFA World Cup, over 92% of substitutions occurred during half-time and the second half, with a higher proportion in knockout stage matches than group stage matches. Group stage substitutions tended to happen earlier, particularly when teams were losing. As allowed substitutions increased, multiple substitutions in one opportunity rose from 4% to 38%. Of the 2,410 substitutions in the six FIFA World Cups, 21.45% were offensive, 63.65% were neutral and 14.90% were defensive. Winning teams made the highest percentage of defensive substitutions, while drawing or losing teams made the highest percentage of offensive substitutions. Match status significantly affected the time of the first three substitutions, and the presence of extra time significantly affected the time of the fourth substitution.
CONCLUSIONS: Analysis of substitutions in FIFA World Cups (2002-2022) reveals: Most substitutions occur during halftime and the second half; Substitutions are earlier in group stages, especially for losing teams; Increased allowed substitutions lead to more multiple-player substitutions; Defensive substitutions are more common when winning, while offensive ones are frequent when drawing or losing; Match status, ranking gap, extra time, game round, and substitution rules significantly influence the time of team substitutions.

The FIFA World Cup, which represents the highest level in football, is regarded as a showcase to unfold the development trends of modern football, thus arousing great interest among researchers. However, most of the previous research designs studied the simple linear correlation between technical indicators and game outcomes, which may overlook the complex causalities in football performance. The aim of current study was to introduce a new method to examine winning patterns emerging from Qatar 2022 through a configurational lens. To this end, fuzzy-set qualitative comparative analysis (fsQCA) was conducted using 98 samples (n = 98) out of 49 Qatar 2022 matches discriminating winning and losing teams in regular time (group stage) and in 30 min of extra time (knockout stage). Then, we selected seven variables as our causal conditions, namely, shots on target, possession, defensive line breaks, crosses, receptions in the final third, forced turnovers, and direct pressures. Necessity analysis and sufficiency analysis of configurations were conducted according to fsQCA requirements. The fsQCA operation showed that no individual causal condition is necessary to winning a game and four configurations were derived from the QCA results and these combinations of conditions fall into three typologies of play style: a possession play style, direct play style, and all-round play style. The results confirmed the fact that football is a complex system and suggested that a winning outcome is often produced by combinations of multiple factors. The findings of the current study contribute to the literature by introducing the configurations of various technical and tactical indicators that could raise the possibility of winning and can be used by practitioners working within the fields of player development, coaching, and match preparation.

This study aimed to explore emergency pharmacy workforce perspectives and experiences in providing pharmaceutical care during mass gathering events (i.e., FIFA World Cup Qatar 2022™).
A qualitative methodology was employed using focus groups discussions. Emergency pharmacists across Hamad Medical Corporation were invited to participate using a combination of purposive and snowball sampling. Focus groups were audio-recorded, transcribed verbatim, and validated. Inductive thematic analysis was undertaken to generate key themes and subthemes.
Four focus groups were conducted which included 21 participants and generated five major themes. Whilst participants had mixed opinions in relation to their preparedness to practice during the World Cup, they perceived their experience as successful and smooth. The primary perceived facilitators were management support, mobile medical units, and high public health awareness. The main highlighted barriers were related to staff insufficiency, medications availability, and cultural and language challenges. Participants recommended pharmacist\'s role identification in mass gatherings, development of pharmacy action plan, and offering simulation training and pharmacy-specific training.
Despite the perceived barriers, pharmacists reported positive views in relation to their experience in providing pharmaceutical care during mass gatherings. Future research should focus on the development of theory-driven action framework for pharmacy departments to adopt during mass gatherings.

We examine the impact of fantasies used in the redevelopment of sport mega-event cities on host communities; particularly as related to the male-dominated FIFA World Cup and forced prostitution. We start with a discussion of event fantasies, particularly those that circulate in relation to humanitarian aid and the alleged involvement of women and children in forced labour and sexual exploitation. We trace these fantasies across several FIFA host cities since the 2006 FIFA World Cup, hosted in Germany, to leverage continual and perpetuate attention (and profit) through the non-profit industrial complex. These fantasies have facilitated and coordinated collaborative consensus amongst state authorities and allies to act in a meaningful manner even as the evidence of forced prostitution is still scant-while the realities of people that continue to be subjected to violent and exploitative labour in the construction of stadia, athlete recruitment, or equipment and apparel industries are seldom addressed. We do this to question the lived impact of policies and personalities of rescue on people engaged, consensually, in erotic labour within host cities, that are often made target of rescue intervention. The figure of the proverbial sex slave, as a highly racialized and hypersexualized trope, is mobilized through the sport mega-event to further police the bodies of all women in labour and migration. We end with a cautious message to future host cities, particularly cities implicated in the 2026 FIFA World Cup within Mexico, Canada, and the United States, of the highly-profitable and politically-advantageous rhetoric of damsel in distress.

UNASSIGNED: The aim of this study is to assess the level of preparedness of pharmacists working in the emergency department at Hamad Medical Corporation (HMC) for any emergency disasters that may take place during the FIFA World Cup Qatar 2022™ by evaluating their awareness (A), attitude (A), and readiness (R).
UNASSIGNED: A cross-sectional quantitative observational study was conducted through a web-based survey. The survey was distributed among emergency pharmacists working in general hospitals under HMC. The questionnaire was composed of three major domains assessing awareness, attitude, readiness, as well as an additional domain to collect the participants\' demographics. Student\'s t-test, analysis of variance, Pearson\'s correlation, and linear regression were used with an alpha level of 0.05.
UNASSIGNED: Most pharmacists working in the emergency departments at HMC had high levels of awareness (76.9%), attitude (92%), and readiness (53.8%) for any emergency disasters that may occur during the FIFA World Cup 2022. Nonetheless, almost half of the respondents reported moderate level of readiness for emergency events. Pharmacists with >10 years\' practice experience had significantly higher AAR score compared to those with <5 years\' experience (P = 0.002). Significant direct positive correlations were found among the 3 AAR parameters (P < 0.05). Attitude was found to be a significant predictor of readiness (P < 0.05). A model composed of attitude and awareness could predict 12% of readiness score.
UNASSIGNED: Emergency pharmacists at HMC have high level of preparedness for any emergency disaster event during the World Cup. Future research should focus on the development of theory-based action framework for pharmacy departments during mass gathering events.

There is a correlation between soccer\'s popularity and states that traditionally vote Democrat in US elections. This has led to claims that where democrats lead, soccer follows. Yet, this relationship may not be entirely stable, as soccer may stimulate the Democratic party vote through its multicultural elements. Using the 1994 World Cup as a plausibly exogenous shock that positioned US soccer, we investigate whether US states that hosted the tournament increased their Democratic vote in future Presidential elections. A two-way fixed-effects estimator and a dynamic difference-in-difference estimator shows that if a US state was a 1994 World Cup host, it increased its Democratic vote share. However, when examining Major League Soccer franchises, this relationship breaks down but recovers when investigating the women\'s World Cup in 1999 and 2003. As the swing states of Florida and Georgia are hosting 2026 World Cup matches, the findings may hold key insights for the 2028 Presidential election.

Recruiting companies recommend elite female soccer players be ≥165 cm (5\'5″) in stature. This study investigated if stature limits match-playing time and performance in elite World Cup soccer among players, positions, and countries. We hypothesized stature would not affect match-playing time or performance. Descriptive data were collected on 552 players from 2019 FIFA Women\'s World Cup. Odds ratios determined likelihood of starting for players <165 cm and ≥165 cm. ANOVAs compared playing time between stature groups, among positions, and between countries. Performance factors including assists, goals, attempts, corners, shots blocked, and defending blocks were reported. Independent t-tests compared differences between players (≥165 cm, < 165 cm). Data are reported, mean difference [95% confidence interval] [MD (95%CI)] and effect sizes (ES). On average, 32.3% of players were <165 cm. Of total players, no differences existed in total minutes (F = 0.98, p = 0.32), matches (F = 0.27 p = 0.59), or average minutes per match (F = 0.48, p = 0.49) between stature groups, regardless of position. No differences existed in playing time between players <165 cm and ≥165 cm among any positions (p > 0.05), or between countries (p > 0.05). Taller mid-fielders exhibited greater performance in goals, assists, attempts, shots blocked, and defending blocks (MD [95%CI] ES; assists, -0.44[-0.76,-0.11]0.59, p = 0.009; goals, -0.35[-0.69,-0.01]0.44, p = 0.047); attempts, 3.14[1.38, 4.90]0.80, p = 0.001; corners, 2.04[0.12, 3.95]0.48, p = 0.037; shots blocked, 0.96[0.40, 1.51]0.75, p = 0.001; defending blocks, 0.43[0.32,0.82]0.48, p = 0.035), however, actual differences were minimal. Our findings indicate stature does not inhibit playing and performing elite women\'s soccer, as nearly one-third of players were <165 cm.

Millions of people are looking forward to the biggest event this year \"FIFA World Cup 2022\" taking place in the state of Qatar. This event is an opportunity for people around the world to socialize, connect, celebrate, and enjoy watching football matches. However, the emotional stress experienced by football players and fans during a such major sport event can sometimes result in unfavorable physiological responses that can adversely affect the heart leading to adverse cardiac consequences. In this mini-review, we summarized the evidence and pathophysiology of stress-induced cardiac events during football games, and the potential strategies to prevent stress-induced cardiac events during the FIFA World Cup 2022.
