Key result
Professional football players who sustained in-season hamstring strain injuries had ~18-22% lower pre-season functional and conventional hamstring-to-quadriceps strength ratios (p<0.01).
Why the study?
It remains debatable whether professional football players with low pre-season hamstring-to-quadriceps strength ratios are more susceptible to sustaining in-season hamstring strain injuries.
Does a low pre-season hamstring-to-quadriceps strength ratio predict in-season hamstring strain injuries in professional football players?

Does a low pre-season hamstring-to-quadriceps strength ratio predict in-season hamstring strain injuries in professional football players?
Effect estimate: ~18-22% lower
p-value: p=<0.01
Lower pre-season hamstring-to-quadriceps strength ratios, driven by higher quadriceps concentric torque, are associated with subsequent in-season hamstring strain injuries in professional football players.
Veeck et al. (2023) conducted an observational in Hamstring strain injuries (n=17). In-season hamstring strain injury vs. No in-season hamstring strain injury (uninjured players) was evaluated on Pre-season functional (FR) and conventional (CR) hamstring-to-quadriceps ratios (~18-22% lower, p=<0.01). Professional football players who sustained in-season hamstring strain injuries had ~18-22% lower pre-season functional and conventional hamstring-to-quadriceps strength ratios (p<0.01).
