In this episode of The Progress Theory, host Dr Phil Price invites physiologist and researcher Dr Tom Jones from Northumbria University to discuss the intricacies of concurrent training. They delve into the concept of the interference effect—a phenomenon where endurance training can attenuate strength gains—and explore how various training modalities, intensities, and volumes can be manipulated to minimise this effect. Dr Jones shares insights from his varied research experience across different sports, including his work with the Newcastle United Academy and the Swedish Winter Sports Research Centre. The conversation touches on the real-world application of concurrent training principles, crucial mistakes to avoid, and the latest scientific understanding of acute molecular signalling. Whether you're a coach, athlete, or fitness enthusiast, this episode offers valuable knowledge on optimising concurrent training for peak performance. Join us for a deep dive into the science of training with Dr Tom Jones on The Progress Theory!

Takeaways
🔹 Volume Matters: The greater the volume of aerobic training, the more likely it is to interfere with strength development. Understanding and managing training volumes are crucial for avoiding this interference effect.
🔹 Fatigue Management: Concurrent training requires careful programming. Avoiding residual fatigue from aerobic workouts can help optimise strength and power training sessions.
🔹 Effective Communication: A lack of appreciation for the physical demands of technical skills sessions can lead to common programming mistakes. Ensuring technical coaches understand these demands is vital for coherent training weeks aligned with specific mesocycle goals.
