The peak match speed of soccer players: a 20 second analysis
To assess peak speeds, usually assess players capacity to quickly accelerate and achieve/maintain a maximal speed in 30 m distance (Altmann et al., 2019). During these tests, players often start from stationary positions, reacting to a sound signal (Haff & Triplett, 2016). However, one may question these test procedures since peak speeds achieved during tests generally exceed peak speeds registered during matches (Buchheit et ak, 2021; Djaoui et al., 2017). Additionally, during matches, soccer players usually perform leading sprints (those where players achieved the sprint threshold [> 25.2 km/h)] while entering the high-speed running category [19.8-25.2 km/h] in the previous 0.5 seconds than explosive sprints (those where players reached the sprint threshold without entering the high-speed running category in the previous 0.5 seconds) (di Salvo et al., 2009). This research aimed to characterize match peak speeds, during a 20-second time window (10 seconds immediately before and after the match peak speed), in soccer matches. Twenty elite soccer players were monitored with GNSS devices during six soccer matches from the Brazilian first division. For each player during each match, speeds were collected at 0.1-second intervals (10 Hz) from 10 seconds before and 10 seconds after the match peak speed. Speeds (mean ± SD) were calculated for speeds at each 0.1-second intervals and intra-individual speed differences were compared at every second of the 20 seconds window using paired mean differences. Effect sizes (ES) were established as trivial (<0.2), small (0.2<0.6), moderate (0.6<1.2), large (1.2<2.0), very large (2.0<4.0) and huge (>4.0) with 90% confidence intervals. Match peak speeds ranged from 29.11 km/h to 31.64 km/h. Speeds registered 10 seconds before and 10 seconds after the match peak speed ranged from 5.11 km/h to 9.21 km/h and 6.90 km/h to 7.65 km/h respectively (Figure 1). Speed increased (acceleration) moderately (ES: 0.68 [0.64, 0.72]) 4 seconds before the match peak speed and decreased (deceleration) moderately (ES: -0.73 [-0.77, -0.69]) 3 seconds after the maximal effort (Figure 2). Match peak speeds were achieved from leading starts, which questions the current sprint test procedures. After the match's peak speed, players decelerate quicker than they accelerate but without reaching a full stop. Nevertheless, preparing players for intense decelerations should not be disregarded. Field tests and training sessions should provide a stimulus similar to what is observed during competition.

The Political Economy of Soccer
Football has been largely exempt from the development of the regulatory state and has been left to govern itself. However, new media have raised the profile of the game and globalization has created new pressures as football clubs become pawns in the ambitions of states, consortia and wealthy individuals. Clubs offer an important sense of identity for fans, but the impersonality and distance of ownership can set up new tensions. In addition, corruption in the international governing body has been a significant problem and the sport's symbiotic relationship with gambling continues to be a concern.Wyn Grant examines the political economy of football and its uneasy relationship with the market. There are no off-the-shelf solutions for regulation, he argues, but the complexities of the game and its economic size demand more attention from government.

NA RUA SOARES NÓS VAMOS JOGAR: AS TENSÕES EM TORNO DA PRÁTICA DO FUTEBOL NAS RUAS ENTRE 1910-1919
The article aims to analyze through the case of Soares Street, present in the Gazeta de Noticias newspaper, how the soccer practiced in the streets of the city of Rio de Janeiro, allows us to reflect on tensions that permeate it during 1910-1919. Soccer in the streets shows the symbolic disputes around soccer and the city itself, demonstrating how both are the construction of different social groups. Observar o esporte, assim como a capital da República, sendo resultado de diferentes percepçöes e vivencias e, nao apenas fruto das elites carioca. Os sentidos em torno do jogo estáo sendo disputados da mesma forma como o sentido em volta da própria capital da República. Essas percepçöes tornavam-se um empecilho para que as camadas populares pudessem também estabelecer à capital federal suas representaçöes. Em 1914, por exemplo, o Navarro Foot-ball club tinha seu ground localizado na rua Soares3, apesar de sua sede social ficar estabelecida na travessa Navarro, em Santa
