Key result
High metabolic load weeks linked to ~160% higher noncontact injury risk in professional soccer players.
Why the study?
The study was intended to investigate the relationship between metabolic power average, acceleration and deceleration zones, and noncontact injuries in professional soccer players, and to analyze associated injury risk between high-load versus low-load levels.
Are high metabolic power and accelerometer-based GPS loads associated with increased noncontact injuries in professional soccer players?

Are high metabolic power and accelerometer-based GPS loads associated with increased noncontact injuries in professional soccer players?
High metabolic load and explosive actions measured by GPS are associated with a significantly increased risk of noncontact injuries in professional soccer players.

Nobari, H, Alves, AR, Abbasi, H, Khezri, D, Zamorano, AD, and Bowman, TG. Are metabolic power distribution and accelerometer-based GPS variables associated with odds ratios of noncontact injuries in professional soccer players? J Strength Cond Res 37(9): 1809-1814, 2023-The present study was intended to i) investigate the relationship between metabolic power average (MPA), acceleration (AcZ) and deceleration (DcZ) zones, and their differences (Δ) on 3 load levels with noncontact injuries in professional players throughout a full soccer season and ii) to analyze the injury risk associated between high-load versus low-load levels for each of the aforementioned parameters with odds ratios (OR) and relative risk (RR), respectively. Twenty-one professional soccer players (age = 28.3 ± 3.9 years) were monitored during a full season (48 weeks) through global positioning system (GPS). A relationship between MPA and accelerometer-based GPS, mainly in explosive actions (i.e., AcZs and DcZs), was found. A higher incidence of injuries in the high-load weeks compared with the low-load weeks were reported (mainly in MPA, AcZ1, AcZ2, and DcZ3 variables). Moreover, significant means of OR (mean = 4.3) and RR (mean = 2.6) of noncontact injuries were established in intense periods with higher metabolic load (i.e., power accelerations, AcZ1, x2 = 0.022). Our results may be useful for coaches, sports scientists, and researchers regarding the optimization of the athletes' performance, as well as providing insights about the impact of intense exercise.
High-load weeks may warrant monitoring in soccer; leaves open whether load modification reduces noncontact injuries.

Nobarı et al. (2023) conducted an observational in Noncontact injuries (n=21). High metabolic load (MPA, AcZ, DcZ) vs. Low metabolic load was evaluated on Noncontact injuries (OR 4.3, RR 2.6, p=0.022). High-load weeks with higher metabolic load were associated with a significantly higher risk of noncontact injuries in professional soccer players compared to low-load weeks (mean OR 4.3, mean RR 2.6).
