摘要：Problem Statement: The main competitions of the World Race Walking events calendar occur in cities that are located at sea level (below 700 m). This suggests that an athlete who lives and trains at moderate altitude (2,600 m), must have different atmospheric conditions for training and competing.Approach: Based on our knowledge and literature review, we did not find studies that used altitude training with the taper phase at height above sea level as one of the variables to be included in performance or endurance in fundamental competencies. Purpose: This study aimed to determine the effect oftraining plan with the taper phase at 300-maltitude,contrasted to the taper phase at 2,600-m altitude, on the percentage of velocity at maximal oxygen uptake (%vV̇ O2max),andendurance index (EI) during a 20 km race walking competition in an athlete who lives and trains at the moderate altitude of 2,600 m. Method:An experimental design of a single subject type A-B-A-B was performed. A 28-year-old woman(body height of 160 cm, body weight of 46.0 kg ± 0.2, body mass index of 17.6, and maximal oxygen uptake [V̇ O2max] of 55 mL·min-1·kg-1) participated in this study.The athlete performed 12 competitions of 20 km race walking during four seasons. Every competition was part of a training macrocycle. The athlete performed six training macrocycles with the taper phase at 2,600-m altitude and six training macrocycles with the taper phase at 300-m altitude.Results: There were significant improvements (p< .05) in%v-V̇ O2max andEI when the taper phase was performed at 300-m altitude, compared to those when the taper phase was performed at 2,600-m altitude.Conclusions: The training plan with the taper phase performed at 300-m altitudehas a positive effect on the improvement in %v-V̇ O2maxandEI in an athlete who lives and trains at 2,600 m but competes at sea level.
