Nordic walking (NW) is a physical sports activity that has been sufficiently studied from the point of view of health, but physiological and performance analyses have not been so much. With this study, we intend to analyse the physical work areas, according to ventilatory thresholds, that occur during a NW competition. Four participants of different characteristics anthropometrics (weight 57.6-85.6 kg; height 165.8-178 cm; and fat percentage 14.5-21.5%) gender (3 males and 1 female) and age (15-57 years) who participated in the NW regional championship have been chosen, and their electrocardiographic tracing was recorded using a NUUBO device throughout the race, obtaining average and maximum heart rates (HR) in eight sections of the circuit. Previously, in the laboratory, a maximal stress test was performed to determine the maximum oxygen consumption (VOmax), the first (VT1) and second (VT2) ventilatory threshold (VT). With these data, four work areas were obtained. Most of the sections of the circuit were conducted with average HRs in zone 2a (above average between VT1 and VT2 but below VT2) and peak HRs in zone 3 (between VT2 and VOmax). : We conclude that, with the data collected on HR, VOmax, and VT, the training zones obtained can be related to the heart rates in the different sections of the circuit. This can be used to improve the sports performance of the walkers.
北欧健走（NW）是一项从健康角度已得到充分研究的体育活动，但生理和运动表现分析却并不多。通过本研究，我们打算根据通气阈值分析北欧健走比赛期间出现的身体工作区域。选择了四名参加北欧健走地区锦标赛的不同特征（体重57.6 - 85.6千克；身高165.8 - 178厘米；体脂率14.5 - 21.5%）、性别（3名男性和1名女性）和年龄（15 - 57岁）的参与者，在整个比赛过程中使用NUUBO设备记录他们的心电图，在赛道的八个路段获取平均心率和最大心率（HR）。此前，在实验室进行了最大应激测试以确定最大耗氧量（VOmax）、第一（VT1）和第二（VT2）通气阈值（VT）。利用这些数据，得到了四个工作区域。赛道的大部分路段平均心率处于2a区（高于VT1和VT2之间的平均值但低于VT2），峰值心率处于3区（在VT2和VOmax之间）。我们得出结论，根据收集到的心率、VOmax和VT数据，所获得的训练区域可以与赛道不同路段的心率相关联。这可用于提高步行者的运动表现。
