Abstract

OBJECTIVE

To determine the degree of reproducibility of maximum oxygen consumption (VO2max) among soccer players, using a modified Heck protocol.

METHODS

2 evaluations with an interval of 15 days between them were performed on 11 male soccer players. All the players were at a high performance level; they were training for an average of 10 hours per week, totaling 5 times a week. When they were evaluated, they were in the middle of the competitive season, playing 1 match per week. The soccer players were evaluated on an ergometric treadmill with velocity increments of 1.2 km.h-1 every 2 minutes and a fixed inclination of 3% during the test. VO2max was measured directly using a breath-by-breath metabolic gas analyzer.

RESULTS

The maximum running speed and VO2max attained in the 2 tests were, respectively: (15.6 +/- 1.1 vs. 15.7 +/- 1.2 km.h-1; [P = .78]) and (54.5 +/- 3.9 vs. 55.2 +/- 4.4 ml.kg-1.min-1; [P = .88]). There was high and significant correlation of VO2max between the 2 tests with a 15-day interval between them [r = 0.97; P < .001].

CONCLUSION

The modified Heck protocol was reproducible, and the 15-day interval between the ergospirometric testing was insufficient to significantly modify the soccer players' VO2max values.

摘要

目的

采用改良的赫克方案，确定足球运动员最大摄氧量（VO2max）的可重复性程度。

方法

对11名男性足球运动员进行了两次评估，两次评估间隔15天。所有运动员均处于高水平状态；他们每周平均训练10小时，每周共训练5次。在进行评估时，他们处于比赛赛季中期，每周踢1场比赛。足球运动员在功率计跑步机上进行评估，测试期间速度每2分钟增加1.2 km.h-1，固定坡度为3%。使用逐次呼吸代谢气体分析仪直接测量VO2max。

结果

两次测试中达到的最大跑步速度和VO2max分别为：（15.6 +/- 1.1对15.7 +/- 1.2 km.h-1；[P = 0.78]）和（54.5 +/- 3.9对55.2 +/- 4.4 ml.kg-1.min-1；[P = 0.88]）。两次测试之间间隔15天的VO2max具有高度显著相关性[r = 0.97；P < 0.001]。
