年龄、性别、种族和初始体能对最大 O-2 摄取（(V) 超过点 O-2 max）训练反应的影响尚不清楚。数据来自 435 名白人和 198 名黑人（287 名男性和 346 名女性），年龄为 17-65 岁，在标准化自行车测力计训练之前和之后。个体反应差异很大，但所有组的 (V) 点 O-2 max 均显着增加。男性和女性以及各个年龄段的黑人和白人的反应差异很大。 (V) 点 O-2 max (ml . kg(-1) . min(-1)) 的变化 (Delta) 没有性别差异；女性的初始值较低，相对增长 (%) 较大。黑人一开始的价值观较低，但反应相似。年龄较大的受试者的 Delta 值较低，但百分比变化相似。 O-2 max 点的基线 (V) 与 O-2 max 点的 Delta (V) 相关性不显着，但与百分比变化显着相关。所有年龄组、性别、种族以及初始健康水平的各个年龄段都有高、中、低反应者。在大量久坐的黑人和白人男性和女性的异质样本中，年龄、性别、种族和初始健康状况对标准化训练的 (V) over dot O-2 max 反应几乎没有影响。
Effects of age, sex, race, and initial fitness on training responses of maximal O-2 uptake ((V) over dot O-2 max) are unclear. Data were available on 435 whites and 198 blacks (287 men and 346 women), aged 17-65 yr, before and after standardized cycle ergometer training. Individual responses varied widely, but (V) over dot O-2 max increased significantly for all groups. Responses by men and women and by blacks and whites of all ages varied widely. There was no sex difference for change (Delta) in (V) over dot O-2 max (ml . kg(-1) . min(-1)); women had lower initial values and greater relative (%) increases. Blacks began with lower values but had similar responses. Older subjects had a lower Delta but a similar percent change. Baseline (V) over dot O-2 max correlated nonsignificantly with Delta (V) over dot O-2 max but significantly with percent change. There were high, medium, and low responders in all age groups, both sexes, both races, and all levels of initial fitness. Age, sex, race, and initial fitness have little influence on (V) over dot O-2 max response to standardized training in a large heterogeneous sample of sedentary black and white men and women.
