“…The literature search ( Figure 1 ) returned 421 potentially relevant studies. After the removal of duplicates and application of exclusion criteria, four cross-sectional studies [ 10 , 19 , 20 , 21 ] and one crossover study [ 11 ] were included ( Table 1 ). Raw data had to be requested from the authors of one paper [ 11 ].…”

“…Recently, Giesche et al [ 10 ] and Niederer et al [ 11 ] found that indicating the required landing leg not before but during a jump causes a substantial number of erroneous task executions. Generally, performing an inadequate reactive motor action may trigger injury (e.g., if subsequently colliding with an opponent) or compromise performance (e.g., if subsequently losing the ball).…”

The performance of choice-reaction tasks during athletic movement has been demonstrated to evoke unfavorable biomechanics in the lower limb. However, the mechanism of this observation is unknown. We conducted a systematic review examining the association between (1) the biomechanical and functional safety of unplanned sports-related movements (e.g., jumps/runs with a spontaneously indicated landing leg/cutting direction) and (2) markers of perceptual–cognitive function (PCF). A literature search in three databases (PubMed, ScienceDirect and Google Scholar) identified five relevant articles. The study quality, rated by means of a modified Downs and Black checklist, was moderate to high (average: 13/16 points). Four of five papers, in at least one parameter, found either an association of PCF with task safety or significantly reduced task safety in low vs. high PCF performers. However, as (a) the outcomes, populations and statistical methods of the included trials were highly heterogeneous and (b) only two out of five studies had an adequate control condition (pre-planned movement task), the evidence was classified as conflicting. In summary, PCF may represent a factor affecting injury risk and performance during unplanned sports-related movements, but future research strengthening the evidence for this association is warranted.

“…[3] It is therefore important to shift focus from rehabilitation to secondary/reinjury prevention after a certain period of postsurgical rehabilitation when the set return to sports (RTS) criteria are ful lled. This may help address the persistent challenges posed by modi able reinjury risk factors [4]through preventive training and performance enhancing approaches. [5][6][7] Since primary ACL injury prevention training programmes have been successful at reducing the risk of ACL injuries.…”

“…As most of the preventive programmes, the PEP programme is utilized as a warm-up strategy. Several studies [4,[25][26][27][28] investigated the acute effects of such warm-up programmes (in heathy participants) and a hypothetical positive impact on potential reinjury risk factors under both anticipated and unanticipated conditions in healthy individuals were found.…”

BackgroundIn team-sports such as football or basketball, athletes need to rapidly adapt their motor plans and actions to unanticipated changes in the environment. Unanticipated jump-landing tasks have been found to elevate the risk of non-contact anterior cruciate ligament (ACL) injuries compared to an anticipated condition. ACL-reconstructed individuals may have greater difficulties to maintain neuromuscular control under unanticipated conditions exposing them to a higher reinjury risk during the game. The planned trial aims to investigate the acute effects of a team-sport specific injury prevention programme on potential ACL reinjury risk factors under anticipated and unanticipated jump-landings.Methods and design:Single center randomized controlled crossover trial. Female and male ACL-reconstructed participants cleared for return to sports (≥ 6 months and ≤ 24 months post-reconstruction) will be included. In a randomized sequence and with a washout phase of one week in between, the participants will perform an injury preventive warm-up protocol (PEP; strengthening, flexibility, plyometry and agility) and a standard warm-up program (bicycle ergometer). Both interventions will last for 12 minutes and will be conducted at moderate intensity (BORG scale: 12 to 14). After each warm-up, participants will perform counter movement jumps with single-leg landings on a force plate. Prior to the jump, a left or right footprint (equally distributed) will be indicated on a screen. Under the anticipated condition, the participants will be informed before the jump that the displayed footprint will not change after take-off. Under the unanticipated condition, the participants will not know whether the target landing side will remain the same (consistent with pre-movement expectations) or change (inconsistent). Under both unanticipated conditions, this information will be displayed 0.1 second after take-off and thus approximately 0.3 seconds before landing.Parametric/non-parametric crossover-analyses (carryover-tests and crossover test) for between-conditions comparisons will be applied. Trial registration: German Clinical Trials Register, identification number DRKS00016942. Registered on May 24, 2019.
