Slacklining: A Novel Exercise to Enhance Quadriceps Recruitment, Core Strength and Balance Control

Gabel CP

Quadriceps activation is critical for lower limb movement and subsequent rehabilitation. However, selective quadriceps activation is compromised by impaired neuro-motor activation, loss of function and pain. A recently introduced method of prehab- and rehabilitation exercise to recruit quadriceps is ‘Slacklining’. This is a complex neuromechanical task that involves balance retention on a tightened band where whole-body dynamics drive the response to external environmental changes. A challenge to the implementation of slacklining is the understanding of its mechanisms of action, a standardized protocol for ‘slackline’ training and the incorporation of this technique into exercise programs along with knowledge of the literature supporting its use. This article summarizes the background to the use of slacklining and how it can supplement recovery goals through a stimulating positive therapeutic experience. It details slacklining’s ability to automatically recruit the quadriceps, the research support for this use, the proposed sequential and progressive protocols for both clinical and research application, areas of caution and the directions for future use and research. Slacklining provides a unique composite-chain activity with higher levels of quadriceps activation and recruitment than traditional exercises that are achieved with significantly less exertion. This enables a positive and progressive form of rehabilitation that achieves outcomes at a potentially faster rate. This is of particular relevance for the outpatient setting and circumstances where the quadriceps is inhibited and activation is required.
