摘　　要：本文报告２１５ 名１０～１９ 岁男性儿童少年在跑台上做递增负荷运动实验时达通气阈（ＶＴ）和最大耗氧量（Ｖ·Ｏ２ｍ ａｘ）时各指标的变化。受试者按年龄分组进行统计和比较。结果表明：男童达通气阈（ＶＴ）时在１０～１５ 岁期Ｖ·Ｏ２、Ｖ·Ｏ２／ＨＲ、ＭＶ均随年龄增长而增加，１５～１７ 岁期间保持稳定；１８、１９ 岁年龄组达峰值；ＶＴ时Ｖ·Ｏ２ 占Ｖ·Ｏ２ｍ ａｘ 百分比在５０．７％ ～５６．４％ 之间；Ｖ·Ｏ２ 相对值、Ｖ·Ｏ２ ／ＬＢＭ 均未见随年龄增长的规律；ＨＲ在１５０～１６４ 次／ｍ ｉｎ 范围之间，占ＨＲｍ ａｘ 的７５．４％ ～７９．８％ ；ＶＴ时Ｖ·Ｏ２ 、Ｖ·Ｏ２ ／ＨＲ与Ｖ·Ｏ２ｍ ａｘ 时对应值呈高度相关（０．８８、０．９２）。Changes of items at the point of ventilatory threshold (VT) and maximal oxygen uptake (VO 2max) are studied, while 215 male children and adolescents (aged 10～19) perform a stepped loading treadmill exercise. Subjects are divided into groups by age, with the result statistics and compared. Results show that the values of VO 2, VO 2/HR and MV increase with the flow of age at VT at the age of 10～15, keep stable from 15～17, and reach peak value at 18～19. V· O 2 makes up 50.7～56.4% of V· O 2max at VT. V· O 2 /kg and V· O 2/LBM are not found increase with age, HR varies between 150～164 beats/min, that accounts for 75.4～79.8% of HRmax, the values of V· O 2 V· O 2 /HR at VT and their corresponded values at V· O 2max are highly correlated (r=0.88 r=0.92).
