Plyometric tasks vary in their intensity and specificity, with typical peak ground reaction forces (GRF) ranging from 1.5-7 times body mass.3640 Inappropriate plyometric task choice could thus be expected to cause adverse reactions on an unprepared person after major lower limb injury. This considers i) the plyometric tasks and associated intensity and complexity, ii) the required movement quality and strength to perform these tasks and iii) monitoring considerations, specifically daily monitoring (e.g., pain and swelling, soreness rules) but also monitoring as part of criterion-based ACL functional recovery. Similar to knee extension, quadriceps strength is also a major focus for proper ACL healing, and now is the time where you focus on developing true quadriceps strength. Volume load is the result of many actions during a session or over time (e.g. Risk of secondary injury in younger athletes after anterior cruciate ligament reconstruction: A systematic review and meta-analysis.

Therefore, the aim of this paper is to provide recommendations to clinicians on how to design and implement plyometric training programs for the ACLR patient, as part of the functional recovery process. Slowly begin bending your knee. Remember: hope is a powerful force, and its well worth harnessing through your recovery journey. Careers. Data were analyzed for 503 patients who participated in competitive-level Australian football, basketball, netball, or soccer after ACL reconstruction surgery using a quadruple-strand hamstring autograft. These goals include restoring knee specific factors, neuromuscular function of many muscle groups and types of function (e.g., maximal isolated and functional strength and explosive neuromuscular performance), movement quality and sport-specific fitness.8,9 Although, there is still not an international consensus on ACL rehabilitation, there has been considerable research recently published toward standardizing the ACL rehabilitation journey. In general, the program has some rules or themes which include progressions in intensity and specificity of the movements with progressive increases in entry speeds (vertical loading height/ horizontal velocity), a gradual reduction in GCT, progression from bilateral to unilateral tasks and from linear (vertical to horizontal to lateral) to multi-planar tasks. Involve eccentrically accepting load on one limb and then concentrically developing force and power to accelerate again on one limb.

Typical clearance to return is 6 to 12 months postoperatively. Intensity of plyometric tasks can be considered on the basis of peak GRFs, which typically occur during the eccentric/landing phase, but also peak concentric forces (and power) are important on a performance level. Using the instant feedback from the HydroWorx pool, Cruz also works to adjust an athletes gait as needed to prevent future injuries while focusing on change of direction and stability maintenance on the core. Biomechanical measures during landing and postural stability predict second anterior cruciate ligament after anterior cruciate ligament reconstruction and return to sport. Wathen D. Literature review: Explosive/plyometric exercise. Performing plyometrics in water or on sand has been shown to reduce the high impacts and results in less muscle soreness than performing plyometrics on more rigid surfaces.46 For example, at the appropriate depth of water in the pool, there appears to be a reduction of around 45-60% in peak GRFs recorded from plyometric exercise in water versus on land.39,47.

Gluteus maximus dysfunction: its relevance to athletic performance and injury and how to treat ita clinical commentary. Does plyometric training improve strength performance? It is well accepted that sufficient strength of the lower limb(s) is important for implementation of plyometrics.7275 Inability to accept load would mean a greater reliance on joint complexes (tendon, ligament and joint structures) for passive force absorption.43 Considering the various descriptors of load, it would seem appropriate to have an understanding of the patients ability for compound muscle strength, to be able to tolerate the external ground reaction forces. The timeline for a return to playing sports after an ACL reconstruction completely depends on the severity of the tear and the individual. Swimming Bracing after anterior cruciate ligament (ACL) reconstruction for rehabilitation and functional return to activities has been a common practice. To do this, there is a need to understand the types of plyometrics available, their relative loading/intensity and understand how to systematically incorporate plyometric training as part of the ACL functional recovery pathway.
