Is there a relationship between in-season injury risk and Y balance or vertical jump in elite youth soccer players?
Haraldsdottir K, Baer M, Brickson S, Watson A.
This study in 41 female young elite soccer players (age 12-17) found that the composite Y balance test YBT and vertical jump performance in pre-season did not predict in-season injury incidence. Higher YBT asymmetry may be associated with an increased risk of in-season injury, although this study may have been limited by sample size to identify a statistically significant difference.

Waldén M, Ekstrand J, Hägglund M, McCall A, Davison M, Hallén A, Bengtsson H.
This study on the data provided by the medical staff of 19 teams in 12 countries found that there was no increased match injury incidence or match injury burden following the restart in 2020 after the COVID period compared with other time periods of 2020 and the corresponding periods 2015-2019, but training injury incidence and injury burden were elevated and higher than in 2015-2019.

Ngatuvai MS, Yang J, Kistamgari S Collins CL, Smith GA.
This study on the USA High School Reporting Information Online surveillance system during the 2007-08 through 2018-19 school years found that ACL injuries in soccer were more likely to occur on artificial turf than natural grass in both boys’ soccer (IPR, 1.72 and girls’ soccer (IPR, 1.61), and that a noncontact mechanism predominated both on artificial turf (61.5%) and natural grass (66.4%).
