The interference effect is the phenomenon by which adaptation to concurrent strength training and endurance training is diminished compared to separately training only strength or endurance. This is important for sports like rowing, which requires both great power and great endurance. Rowers must train both strength and endurance, so the challenge of the interference effect in rowing is how to maximize adaptation to, and minimize conflict between, the different forms of training that must necessarily occur concurrently. In this article, we’ll dig into the research on the interference effect in rowing, and discuss practical takeaways for rowers and coaches seeking better training and better performance.
I want to be up front that this gets into a level of detailed training program design that may not be an important factor for you, your rowing program, or the rowers you coach. Master the basics first. Do basic strength training, improve aerobic and anaerobic fitness via multiple means, develop great technique on the water, and of course, make rowing a positive part of your life or the lives of the athletes you coach, and this will yield the greatest results in rowing and beyond. If you have the basics down, if the athletes you coach are sufficiently advanced, and if you have the ability to structure your training program and organize your sessions, research on the interference effect offers us takeaways that might yield small performance improvements that add up in the big picture.
