Attenuated RPE and leg pain in response to short-term high-intensity interval training

► RPE increases with increasing exercise intensity, and is lower with chronic resistance training. ► Leg pain is assessed using a 0-10 scale, and increases with exercise intensity. ► Data report reductions in RPE and leg pain in recovery from 4-6 bouts of interval training. ► Results are due to greater phosphocreatine, muscle glycogen, and oxidative capacity.
