“…16 The average score of the studies was 59.7% indicating "fair" quality with the lowest score of 48.2% 17 and the highest score of 64.3%. [18][19][20][21][22][23] These lower scores were likely due to the fact that the Downs and Black is typically used to grade randomized control trials, and most of the included studies were cohort studies. This resulted in consistently lower scores in areas of internal validity, specifically questions 14, 15, 19, 23, 24, and 25.…”

Purpose: Low injury rates have previously been correlated with sporting team success, highlighting the importance of injury prevention programs. Recent methods, such as acute: chronic workload ratios (ACWR) have been developed in an attempt to predict and manage injury risk; however, the relation between these methods and injury risk is unclear. The aim of this systematic review was to identify and synthesize the key findings of studies that have investigated the relationship between ACWR and injury risk. Methods: Included studies were critically appraised using the Downs and Black checklist, and a level of evidence was determined. Relevant data were extracted, tabulated, and synthesized. Results: Twenty-seven studies were included for review and ranged in percentage quality scores from 48.2% to 64.3%. Almost perfect interrater agreement (κ = 0.885) existed between raters. This review found a high variability between studies with different variables studied (total distance versus high speed running), as well as differences between ratios analyzed (1.50-1.80 versus ≥1.50), and reference groups (a reference group of 0.80-1.20 versus ≤0.85). Conclusion: Considering the high variability, it appears that utilizing ACWR for external (eg, total distance) and internal (eg, heart rate) loads may be related to injury risk. Calculating ACWR using exponentially weighted moving averages may potentially result in a more sensitive measure. There also appears to be a trend towards the ratios of 0.80-1.30 demonstrating the lowest risk of injury. However, there may be issues with the ACWR method that must be addressed before it is confidently used to mitigate injury risk. Utilizing standardized approaches will allow for more objective conclusions to be drawn across multiple populations.

“…This could be explained by the fact that the current study analysed chronic workloads in isolation. It has in fact, been shown in elite football33 that, 3-week chronic workloads ≥2584 AU were protective, but when players also covered a 1-weekly high-speed running (HSR) of 701 m to 750 m. The same 1-weekly HSR distance with low chronic workload (<2584 AU) increased injury risk. This highlights the importance of future studies and practitioners to analyse chronic workloads in conjunction with other parameters such as external running workloads.…”

“…Our results additionally suggest that rescheduling the exercises in Part 2 so that they are performed more regularly reduces ankle injury incidence, hamstring injury severity, and injury recurrence. We speculate that by significantly reducing the number of severe injuries and reducing time lost to injury, players in the P2 post group returned to training earlier, increased their exposure to the 11+ program as well as to football training, and, in turn, reduced the injury risk caused by de‐training for the most common injuries in football …”

Although the 11+ program has been shown to reduce injuries in sub‐elite football, program compliance is typically poor, suggesting that strategies to optimize delivery are necessary. This study investigated the effect of rescheduling Part 2 of the three‐part 11+ program on program effectiveness. Twenty‐five semi‐professional football clubs were randomly allocated to either a Standard‐11+ (n = 398 players) or P2post group (n = 408 players). Both groups performed the 11+ program at least twice a week throughout the 2017 football season. The Standard‐11+ group performed the entire 11+ program before training activities commenced, whereas the P2post group performed Parts 1 and 3 of the 11+ program before and Part 2 after training. Injuries, exposure, and individual player 11+ dose were monitored throughout the season. No significant between group difference in injury incidence rate (P2post vs Standard‐11+ = 11.8 vs 12.3 injuries/1000 h) was observed. Severe time loss injuries > 28 days (33 vs 58 injuries; P < .002) and total days lost to injury (4303 vs 5815 days; P < .001) were lower in the P2post group. A higher 11+ program dose was observed in the P2post (29.1 doses; 95% CI 27.9‐30.1) versus Standard‐11+ group (18.9 doses; 95% CI 17.6−20.2; P < .001). In semi‐professional football, rescheduling Part 2 of the 11+ program to the end of training maintained the effectiveness of the original 11+ program to reduce injury incidence. Importantly, rescheduling Part 2 improved player compliance and reduced the number of severe injuries and total injury burden, thereby enhancing effectiveness of the 11+ program.

High-speed running and sprinting as an injury risk factor in soccer: Can well-developed physical qualities reduce the risk?

Abstract: Exposing players to large and rapid increases in HSR and SR distances increased the odds of injury. However, higher chronic training loads (≥2584 AU) and better intermittent aerobic fitness off-set lower limb injury risk associated with these running distances in elite soccer players.
