Abstract: Objective: To study the influence of attentional focus strategies on sprint strength training and energy saving through kinematic and physiological experiment of special strength training methods under the guidance of different attentional focus strategies.The results show that the effects of special strength training under the guidance of different attention focus strategies present significant differences. External attentional focus strategies bring about better effects for sprint strength training; muscle electrical activity intensity, gas metabolism and energy consumption in special strength trainings vary under the guidance of different attentional focus strategies.Muscle electrical activity intensity was weaker, both gas metabolism and energy consumption were lower under the guidance of external attentional focus strategies, thus saving the energy in the training process and making movement pattern more economy.

Key words: attentional focus strategies, special strength training, training effect, energy saving, sprint
