6.3 心率无氧阈(HR-AT)的确定 虽然VO_2max决定了有氧能力的潜力,然而运动员能否有效地利用它持续运动、同时不伴有血乳酸的堆积则更有意义。AT便能客观地反映VO_2max的利用能力。Costill[6]、Kinderman等人[7]的研究证实,同VO_2max相比,AT与亚极限负荷时有氧耐力效率的标志,AT训练目前在耐力项目的训练中已得到广泛的应 6.3 Determination of heart rate anaerobic threshold (HR-AT) Although VO_2max determines the potential for aerobic capacity, it is more meaningful for an athlete to effectively utilize it for sustained exercise without the accumulation of blood lactate. AT can objectively reflect the utilization of VO_2max. Studies by Costill [6] and Kinderman et al. [7] have demonstrated that AT training has been widely used in endurance training as compared with VO_2max, a sign of AT and sub-ultimate aerobic endurance
