- Purpose To examine differences between men and women football players in clinically feasible jumping measures. Methods Female football players (N=46, ages 16-25) were matched based on age, training frequency, and playing position with 46 male players. All players performed the tuck jump and drop vertical jump (DVJ). DVJ was assessed quantitatively for valgus knee motion and probability of a high peak knee abduction moment (pKAM), as well as sagittal plane hip, knee, and ankle angles, and qualitatively with visual assessment of the players knees upon landing; graded as good, reduced, or poor control. Result Women had higher total tuck jump scores (52) (more technique flaws), than men (3 +/- 2, Pamp;lt;0.01). The quantitative analysis of the DVJ found that men had greater asymmetries between limbs, but women landed bilaterally in more knee valgus (interaction P=0.04, main effect of sex P=0.02). There was no difference in pKAM (interaction n.s.). Women also landed in less hip flexion (P=0.01) and ankle dorsiflexion (P=0.01) than men. The qualitative DVJ analysis found that more women (48%) had poor knee control compared to men (11%, Pamp;lt;0.01). Conclusions The results indicate that women perform worse on the tuck jump assessment than men. The results support previous findings that women land in more knee valgus than men, but also found that men may have larger asymmetries in knee valgus. These results from clinically feasible measures provide some suggestions for clinicians to consider during ACL reconstruction rehabilitation to enhance performance.

- PurposeTo determine if female football players who had longer durations of rehabilitation, measured in months, after anterior cruciate ligament reconstruction would have lower tuck jump scores (fewer technique flaws) and smaller asymmetries during drop vertical jump landing.MethodsOne-hundred-and-seventeen female football players, aged 16ￜ25 years, after primary unilateral ACL reconstruction (median 16 months, range 6ￜ39) were included. Athletes reported the duration of rehabilitation they performed after anterior cruciate ligament reconstruction. Athletes also performed the tuck jump and drop vertical jump tests. Outcome variables were: tuck jump score, frontal plane knee motion and probability of peak knee abduction moment during drop vertical jump landing.ResultsThere was no difference in tuck jump score based on duration of rehabilitation (n.s.). No interaction (n.s.), difference between limbs (n.s.), or duration of rehabilitation (n.s.) was found for peak knee abduction moment during drop vertical jump landing. No interaction (n.s.) or difference between limbs (n.s.) was found for frontal plane knee motion, but there was a difference based on duration of rehabilitation (P?=?0.01). Athletes with >?9 months of rehabilitation had more frontal plane knee motion (medial knee displacement) than athletes with ConclusionAs there was no difference in tuck jump score or peak knee abduction moment based on duration of rehabilitation, the results of this study press upon clinicians the importance of using objective measures to progress rehabilitation and clear athletes for return to sport, rather than time alone.

- Background: The tuck jump assessment was developed to identify players at risk for anterior cruciate ligament (ACL) injuries or gauge a players progress through rehabilitation after ACL reconstruction. A tuck jump score of >= 6 out of 10 has been labeled poor and thought to identify players with high risk landing patterns. Purpose: The purpose of this exploratory study was to examine if there was a relationship between tuck jump score, particularly tuck jump scores >= 6, hopping performance, and patient-reported outcome measures in female soccer players with ACL reconstruction (ACLR) and knee-healthy controls. Study Design: Secondary analysis of prospective cohort study Methods: Female soccer players (117 after ACLR, 117 knee-healthy) performed the single hop for distance, tuck jump assessment, and drop vertical jump (DVJ). All players were categorized based on as having a total tuck jump score >= 6 or < 6. Analyzing all players together, Spearmans rank correlations assessed if there were relationships between total tuck jump score or tuck jump scores >= 6 and single-legged hop limb symmetry or DVJ measures. Players with an ACLR also filled out the International Knee Documentation Committee 2000 Subjective Knee Form and the Knee injury Osteoarthritis Outcome Score. Spearmans rank correlations assessed if there were relationships between total tuck jump score or tuck jump scores >= 6 and patient-reported outcome measures. Results: The mean tuck jump scores was 4.8 +/- 1.8 (tuck jump score >= 6, 6.7 +/- 0.9, tuck jump score < 6, 3.7 +/- 1.1) with 87 (37%) athletes having tuck jump score >= 6. There were no significant relationships between tuck jump score or tuck jump score >= 6 and hopping performance or patient-reported outcome measures. Conclusion: The results of this current study indicate that tuck jump scores, including tuck jump scores >= 6, may not be related to functional or patient-reported outcome measures. Further work is needed to examine the clinical utility of the tuck jump assessment.

- The role of psychological processes in team sports has been studied extensively. The chapter focuses on the psychological factors that are unique to basketball. These factors include the following: (a) free throw shooting—examining the role of gaze behavior in enhancing shooting percentages, (b) “the hot hand”—the underlying mechanisms leading to a “hot streak,” (c) clutch performance under pressure—why some players choke in critical game situations while others flourish, and (d) team decision-making—team performance as a unit which operates with optimal coordination and communication. This chapter consists of research findings and theoretical insights to capture the mechanisms leading to enhanced psychological skills and expert performance. Furthermore, this chapter provides guidelines for improving performance by transferring the knowledge gained from research to the applied domain. General psychological skills such as preperformance routine, decision-making, and attention are examined throughout the chapter. A final summary of findings including limitations in the current literature and future directions to enhance the domain are provided.

- To help clinicians improve outcomes through better utilisation of rehabilitation after ACLR, we offer four suggestions:The importance of regaining function after ACLR must be recognised by all stakeholders: policymakers (third-party payers), orthopaedic surgeons, rehabilitation clinicians, coaches and athletes (and their parents/guardians when under age).Orthopaedic surgeons and rehabilitation clinicians must join forces to promote evidence-based practice, including the use of objective measures for progression and RTS.Evidence-based patient education should occur before all surgical or rehabilitation decision-making, and continue as rehabilitation progresses. This will ensure that the athlete can make an informed commitment to a treatment plan.Orthopaedic surgeons and rehabilitation clinicians must acknowledge their roles in building and maintaining athlete motivation for rehabilitation.
