To determine the cardiorespiratory response to maximal exercise before, during and after the pubescent growth spurt, thirty boys were tested at yearly intervals over a period of six consecutive years. For each individual, peak height velocity (PHV) was determined. The age at PHV (X = 13.6 years) was taken as a standard of maturation. The results from all subjects at 1.5 and 0.5 years before and 0.5 and 1.5 years after PHV are presented. The highest oxygen uptake (VO2) obtained during an incremental bicycle ergometer test to voluntary exhaustion was taken as peak oxygen uptake (VO2 peak). Across each of the four years studied, mean VO2 peak (min = 49.6; max = 52.5 ml.kg-1.min-1) and mean heart rate (HR) at VO2 peak (min = 190; max = 192) did not change significantly as a function of PHV. On the other hand, the respiratory quotient at VO2 peak increased considerably from mean minima and maxima of 0.99 and 1.01 before PHV to 1.07 and 1.10 after PHV. Ventilatory equivalent for VO2 (VE/VO2), taken as an indicator of ventilatory economy, seemed to be unaffected by the maturation process. The steepest increase in circumpubertal oxygen pulse was found one year after PHV. Average stability coefficients (r), calculated from the inter-years correlations were high for height (r = 0.95), weight (r = 0.92), HR at VO2 peak (r = 0.74), VO2 peak in 1/min (r = 0.71), oxygen pulse (r = 0.68) and tidal volume (r = 0.64).
为了确定青春期生长突增前、期间和之后对最大运动的心肺反应，30名男孩在连续六年的时间里每年接受一次测试。对于每个个体，确定其身高峰值速度（PHV）。将出现PHV时的年龄（X = 13.6岁）作为成熟度的标准。呈现了所有受试者在PHV前1.5年和0.5年以及PHV后0.5年和1.5年的结果。在递增式自行车测力计测试至自愿疲劳期间获得的最高摄氧量（VO2）被视为峰值摄氧量（VO2峰值）。在研究的四年中，平均VO2峰值（最小值 = 49.6；最大值 = 52.5 ml·kg⁻¹·min⁻¹）和VO2峰值时的平均心率（HR）（最小值 = 190；最大值 = 192）并未随PHV发生显著变化。另一方面，VO2峰值时的呼吸商从PHV前的平均最小值0.99和最大值1.01大幅增加至PHV后的1.07和1.10。作为通气经济性指标的VO2通气当量（VE/VO2）似乎未受成熟过程的影响。在PHV后一年发现青春期周围氧脉搏的增幅最大。根据年份间的相关性计算得出的平均稳定性系数（r），对于身高（r = 0.95）、体重（r = 0.92）、VO2峰值时的心率（r = 0.74）、每分钟VO2峰值（r = 0.71）、氧脉搏（r = 0.68）和潮气量（r = 0.64）而言都很高。
