Taekwondo study reveals best combat rest strategy

This study looked at how changing the work-to-rest ratio during taekwondo combats affects athletes' bodies. Twenty experienced taekwondo athletes did three types of simulated combats: free style, 1:2 work-to-rest, and 2:1 work-to-rest. Researchers measured heart rate, blood lactate, jump performance, and how hard the athletes felt they were working.
