In team sports, the sport-specific skills involve many types of explosive and agility movements. Previous studies have reported that re-warm-up activities may attenuate the reduction in performance which induced by passive rest during half-time. Therefore, this brief review investigates the effects of different re-warm-up strategies during half-time on exercise performance, and possible physiological mechanisms. Most of studies used the physiological mechanism of warm-up activity to explain the improvements in performance after re-warm-up activity. The re-warm-up activities might maintain body temperature, speed up oxygen uptake kinetics, increase oxygen availability in exercising muscles, and induce post-activation potentiation. The re-warm-up strategies might include continuous exercise, interval exercise, and strength or explosive exercise. It is recommended to select an appropriate re-warm-up strategy according to the fatigue level, available equipment, and rules, instead of passive rest, before the start of the second half. However, further studies are needed to clarify the optimum re-warm up strategy and exact physiological mechanism. |
