This systematic review on 104 studies found that the range of relative distances covered across small-sided games, medium-sided games, and large-sided games was 14.8 to 17.2 m.min-1 for high-speed running, 2.7 to 3.6 m.min-1 for very high-speed running, and 0.2 to 0.7 m.min-1 for sprinting. High-speed running parameters showed poor reliability with a pooled coefficient of variation of 22.8% related with device speed thresholds, pitch dimension, and game orientation.

This systematic review included 421 elite athletes in wrestling, baseball, soccer, rugby or handball. 77.7% patients received partial meniscectomy and 22.3% meniscal repair. After partial meniscectomy, 78.3% returned to their pre-injury activity levels, and a total of 12 (3.7%) patients, 10 of them with involvement of the lateral meniscus, required revision surgery. After meniscal repair, 75.5% patients returned to their pre-injury activity levels, and 16 (17.0%) required partial meniscectomy. Athletes required more time after meniscal repair, while meniscectomy was associated with a high risk of developing knee osteoarthritis over the years.
Extended Knee Control programme lowers weekly hamstring, knee and ankle injury prevalence compared with an adductor strength programme or self-selected injury prevention exercises in adolescent and adult amateur football players: a two-armed cluster-randomised trial with an additional comparison arm.

This study on amateur football teams found that 17 teams that implemented an extended version of the Knee Control injury prevention exercise programme (IPEP) during a 7-month season had similar incidence of hamstring, knee and ankle injuries than 12 teams using an adductor strength programme, but 29% lower incidence that 17 teams already using a self-selected IPEP.
