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 ).

“…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.

“…Beyond this, using free- or bodyweight resistance exercise could also be of value as a warm-up for athletes from both an injury-preventive and a performance-related perspective. Giesche et al [ 53 ] examined the relation between inhibitory control and dynamic postural control during unplanned single-leg landings in healthy active individuals. Participants with low S cw values had higher center of pressure path lengths, which is indicative of a possible stability deficit.…”

Free-Weight Resistance Exercise Is More Effective in Enhancing Inhibitory Control than Machine-Based Training: A Randomized, Controlled Trial

Resistance exercise has been demonstrated to improve brain function. However, the optimal workout characteristics are a matter of debate. This randomized, controlled trial aimed to elucidate differences between free-weight (REfree) and machine-based (REmach) training with regard to their ability to acutely enhance cognitive performance (CP). A total of n = 46 healthy individuals (27 ± 4 years, 26 men) performed a 45-min bout of REfree (military press, barbell squat, bench press) or REmach (shoulder press, leg press, chest press). Pre- and post-intervention, CP was examined using the Stroop test, Trail Making Test and Digit Span test. Mann–Whitney U tests did not reveal between-group differences for performance in the Digit Span test, Trail Making test and the color and word conditions of the Stroop test (p > 0.05). However, REfree was superior to REmach in the Stroop color-word condition (+6.3%, p = 0.02, R = 0.35). Additionally, REfree elicited pre-post changes in all parameters except for the Digit Span test and the word condition of the Stroop test while REmach only improved cognitive performance in part A of the Trail Making test. Using free weights seems to be the more effective RE method to acutely improve cognitive function (i.e., inhibitory control). The mechanisms of this finding merit further investigation.

“…landing on the wrong side). [18][19][20] According to a previous study, [20] these decreases of biomechanical landing safety and decision-making quality under the unanticipated relative to anticipated can be de ned as 'unanticipated landing costs'. These unanticipated landing costs may contribute to an increase in the residual risk for reinjury following RTS.…”

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.
