Periodization and Sovereignty
Despite all recent challenges to stage-oriented histories, the idea of a division between a \"medieval\" and a \"modern\" period has survived, even flourished, in academia.Periodization and Sovereigntydemonstrates that this survival is no innocent affair. By examining periodization together with the two controversial categories of feudalism and secularization, Kathleen Davis exposes the relationship between the constitution of \"the Middle Ages\" and the history of sovereignty, slavery, and colonialism. This book's groundbreaking investigation of feudal historiography finds that the historical formation of \"feudalism\" mediated the theorization of sovereignty and a social contract, even as it provided a rationale for colonialism and facilitated the disavowal of slavery. Sovereignty is also at the heart of today's often violent struggles over secular and religious politics, and Davis traces the relationship between these struggles and the narrative of \"secularization,\" which grounds itself in a period divide between a \"modern\" historical consciousness and a theologically entrapped \"Middle Ages\" incapable of history. This alignment of sovereignty, the secular, and the conceptualization of historical time, which relies essentially upon a medieval/modern divide, both underlies and regulates today's volatile debates over world politics. The problem of defining the limits of our most fundamental political concepts cannot be extricated, Davis argues, from the periodizing operations that constituted them, and that continue today to obscure the process by which \"feudalism\" and \"secularization\" govern the politics of time.

Monitoring Accumulated Training and Match Load in Football: A Systematic Review
(1) Background: Training load monitoring has become a relevant research-practice gap to control training and match demands in team sports. However, there are no systematic reviews about accumulated training and match load in football. (2) Methods: Following the preferred reporting item for systematic reviews and meta-analyses (PRISMA), a systematic search of relevant English-language articles was performed from earliest record to March 2020. The search included descriptors relevant to football, training load, and periodization. (3) Results: The literature search returned 7972 articles (WoS = 1204; Pub-Med = 869, SCOPUS = 5083, and SportDiscus = 816). After screening, 36 full-text articles met the inclusion criteria and were reviewed. Eleven of the included articles analyzed weekly training load distribution; fourteen, the weekly training load and match load distribution; and eleven were about internal and external load relationships during training. The reviewed articles were based on short-telemetry systems (n = 12), global positioning tracking systems (n = 25), local position measurement systems (n = 3), and multiple-camera systems (n = 3). External load measures were quantified with distance and covered distance in different speed zones (n = 27), acceleration and deceleration (n = 13) thresholds, accelerometer metrics (n = 11), metabolic power output (n = 4), and ratios/scores (n = 6). Additionally, the internal load measures were reported with perceived exertion (n = 16); heart-rate-based measures were reported in twelve studies (n = 12). (4) Conclusions: The weekly microcycle presented a high loading variation and a limited variation across a competitive season. The magnitude of loading variation seems to be influenced by the type of week, player’s starting status, playing positions, age group, training mode and contextual variables. The literature has focused mainly on professional men; future research should be on the youth and female accumulated training/match load monitoring.

The Training Characteristics of World-Class Distance Runners: An Integration of Scientific Literature and Results-Proven Practice
In this review we integrate the scientific literature and results-proven practice and outline a novel framework for understanding the training and development of elite long-distance performance. Herein, we describe how fundamental training characteristics and well-known training principles are applied. World-leading track runners (i.e., 5000 and 10,000 m) and marathon specialists participate in 9 ± 3 and 6 ± 2 (mean ± SD) annual competitions, respectively. The weekly running distance in the mid-preparation period is in the range 160–220 km for marathoners and 130–190 km for track runners. These differences are mainly explained by more running kilometers on each session for marathon runners. Both groups perform 11–14 sessions per week, and ≥ 80% of the total running volume is performed at low intensity throughout the training year. The training intensity distribution vary across mesocycles and differ between marathon and track runners, but common for both groups is that volume of race-pace running increases as the main competition approaches. The tapering process starts 7–10 days prior to the main competition. While the African runners live and train at high altitude (2000–2500 m above sea level) most of the year, most lowland athletes apply relatively long altitude camps during the preparation period. Overall, this review offers unique insights into the training characteristics of world-class distance runners by integrating scientific literature and results-proven practice, providing a point of departure for future studies related to the training and development in the Olympic long-distance events.

The fabric of historical time
Historical time is a notoriously elusive notion. Yet, as societies attempt to make sense of rapidly changing worlds, it gains a new significance in the twenty-first century. This title sketches a theory of historical time as based on a distinction between temporality and historicity. It approaches the fabric of historical time as varying relational arrangements and interactions of multiple temporalities and historicities.

Is it possible to propose a periodization strategy different from the inverted U in preseason? A comparison between two professional football teams
Purpose: the main aim of this study was to quantify and compare the weekly external loads of pre-season in two professional football teams. Methods: GPS devices monitored forty-five players in two teams daily in a five-week pre-season period. The external load measures were: number of sessions, total duration, acceleration load (aLoad), total distance (TD), distance at >21 km·h-1 (TD21), distance at >24 km·h-1 (TD24) and Player-Load® (PL). Results: there were differences in the weekly external load between both teams. Team1 trained 30% more time and training sessions than Team2, so the weekly load for all external load variables was higher except for aLoad and TD21 for W1 (Team2>Team1, p<0.05). These differences between teams were not similar for all weeks, with higher differences in weeks 2, 3, and 4. While Team2 proposed a distribution more stable and progressive in high-speed distances (TD21 and TD24) among weeks, Team1 used the inverted U model. In this line, variations between weeks were lower for Team2 (from -4% to 38%) than for Team1 (from -26% to 1,653%). Conclusions: The study's main conclusion was that in addition to a load management with an inverted U model, more widespread in professional football, a more stable and progressive distribution strategy can be proposed in pre-season in a professional setting. Keywords: GPS, training load, team sports, periodization, monitoring.
