Lead researcher James Alexander conducted the research after discussions with runners about stretching. Mr Alexander is an avid jogger and often wondered what the benefits of stretching were. He told the Reuters news agency that: "Runners have certain beliefs around running injury risks, injury prevention and performance that are in contrast to current research evidence." He added: "These beliefs drive runners to continue to pursue ineffective or non-optimal strategies within their running training, whether through static stretching for injury prevention or low-load strength training for performance." He recommended a 5-10-minute session of walking or light jogging as the best warm-up.
