Abstract

OBJECTIVE

To examine the correlation of peak oxygen uptake (VO2 peak), velocity at lactate threshold (V(LT)), and running economy (RE) in a group of Special Force Squad members.

METHODS

VO2 peak, V(LT), and RE of 120 male elite special force police squad members (VO2 peak, 57.4 +/- 4.3 mL minute(-1) kg(-1); age, 28.9 +/- 5.2 years; body mass index, 24.2 +/- 1.6 kg m(-2)) were tested using an incremental treadmill protocol (2.4 m second(-1), increase 0.4 m second(-1) every 5 minutes). Running velocities at the first lactate inflection point (V(LT)) and blood lactate concentration at 4 mmol L(-1) (V4) were determined. RE was defined as oxygen uptake in mL kg(-1) minute(-1) at 3.2 m second(-1).

RESULTS

Analysis revealed little or no correlation between V4, V(LT), VO2 peak, and RE (r = 0.02-0.35; p = 0.01-0.80).

CONCLUSIONS

(1) VO2 peak, V(LT), and RE do not correlate in elite squad members. (2) All 3 variables should be assessed when comparing inter- and intraindividual differences in endurance performance of Special Force Squad members.

摘要

目的

研究一组特种部队队员的最大摄氧量（VO2峰值）、乳酸阈速度（V（LT））和跑步经济性（RE）之间的相关性。

方法

采用递增式跑步机方案（2.4米/秒，每5分钟增加0.4米/秒）对120名男性精英特种部队警察队员（VO2峰值，57.4±4.3毫升·分钟-1·千克-1；年龄，28.9±5.2岁；体重指数，24.2±1.6千克·米-2）的VO2峰值、V（LT）和RE进行测试。测定第一个乳酸拐点处的跑步速度（V（LT））和血乳酸浓度为4毫摩尔/升时的速度（V4）。RE定义为3.2米/秒时的摄氧量（毫升·千克-1·分钟-1）。
