In this episode of the Pacey Performance Podcast, Fearghal Kerin, Rehabilitation Physiotherapist, Chelsea Football Club, discusses the growing prevalence of T-junction hamstring injuries and the importance of location-specific rehabilitation strategies.

Fearghal outlines his background, highlighting his PhD focused on hamstring injuries and his work in professional sports, including football and rugby. He emphasizes the evolving role of strength and conditioning coaches in injury rehabilitation and the need for a nuanced approach to managing hamstring injuries based on their anatomical location.

Hamstring injuries are classified into sprint-type and stretch-type, with the T-junction—a confluence of the long and short head of the biceps femoris—being particularly susceptible to injury. This area is complex due to its dual force vectors, dual nerve supply, and bi-articular function, making it challenging to rehabilitate.

Fearghal discusses the necessity of considering biomechanical positions and sport-specific actions when diagnosing and treating hamstring injuries. He highlights that traditional low-level resistance exercises may not effectively prepare athletes, advocating for high-intensity conditioning contractions instead.

He stresses the importance of eliminating MRI signs before returning to play, as unresolved edema and tension can increase the risk of reinjury. Specific tissue loading and exercise selection are crucial, with a focus on exercises that respect the injury’s anatomical structure.

Research indicates that T-junction injuries, though complex, do not necessarily lead to worse outcomes than other hamstring injuries if managed correctly. This podcast concludes with a call for more research and personalized rehabilitation strategies to optimize recovery and prevent recurrence.

In this episode of the Pacey Performance Podcast, Gerard McMahon joins us to discuss "activation" exercises and their role in improving performance and preparation. Activation exercises have long been touted for their ability to improve performance by targeting specific muscle groups and maximizing motor unit recruitment. However, Gerard challenges this notion, suggesting that these exercises, often misunderstood and misapplied, may not be as beneficial as many people think.

Gerard explains that muscle activation is fundamentally a function of the neuromuscular system, controlled by motor unit recruitment and firing rates. Activation exercises, while intended to improve performance, often do not significantly enhance muscle activation in healthy athletes. Instead, these exercises may be more appropriate for rehabilitation of severe cases or specific disabilities.

EMG (electromyography) studies, commonly used to measure muscle activation, have limitations due to the complexity of interpreting muscle signals and potential inaccuracies from surface electrodes. As a result, the practical value of EMG-based activation exercises is questioned. Low-level resistance band exercises, such as monster walks and side steps, are criticized for their minimal impact on performance enhancement. These exercises, often used in warm-ups, may not provide the necessary muscle activation levels to prepare athletes effectively for high-intensity activities.

Gerard suggests that high-intensity contractions are a better alternative for post-activation potentiation, which can lead to greater performance improvements. These high-intensity activities, combined with a proper warm-up, are more effective in enhancing neuromuscular readiness and overall athletic performance. In summary, the podcast casts doubt on the traditional use of activation exercises, advocating for high-intensity exercise in the form of PAP as a superior method for athlete preparation and performance enhancement.

Main talking points:

• Reevaluate the effectiveness of activation exercise
