为了评估运动中血容量(BV)和血浆容量(PV)的个体差异之间的关系，我们测量了13名男性志愿者在跑步机运动直到精疲力竭时的BV和PV的变化。乳酸阈值(LT)作为有氧运动能力的预测指标，是根据血乳酸浓度升高到4 mmol时的运动强度计算出来的。VO2峰值与BV呈显著正相关。肺活量变化与总肺活量呈显著正相关，维持循环血容量。(C)2004爱思唯尔有限公司。保留所有权利。
To assess the relationship between blood volume (BV) and the reduction in plasma volume (PV) during exercise in individual variations, we measured BV and changes in PV in thirteen male volunteers during treadmill exercise until exhaustion. The lactate threshold (LT), as a predictor of aerobic exercise capacity, was calculated from the exercise intensity at the point of plasma lactate concentration buildup to 4 mmol. The relationship of peak VO2 with BV indicated a significant positive correlation. The strong positive relation between the shifts in PV and total PV, and resulted in a maintenance of the circulating BV. (C) 2004 Elsevier Ltd. All rights reserved.
