More than half of all swimmers might not benefit from their usual competition warm-up

Interesting post here on Sweat Science, on how researchers at University of Alabama put 16 NCAA swimmers through three 50-yards sprints on separate days, so that each tried one without any warm-up at all, one with a short, standardized 2×50 yard warm-up, and one with the swimmers’ usual individual warm-ups, averaging about 1300 meters. The result was that most benefited from their usual warm-up, but as it is also pointed out, that 19% actually had their best time after the short warm-up, and 37% after no warm-up at all. Leaving only 44% or less than half benefiting from their usual warm-up.
