Artistic swimmers (AS) are exposed to repeated apnoeas in the aquatic environment during high intensity exercise provoking specific physiological responses to training, apnoea, and immersion. This study aimed to evaluate the changes in lung diffusing capacity in AS pre-, mid- and post-training in a combined session of apnoeic swimming, figures and choreography. Eleven elite female AS from the Spanish national team were the study's participants. The single-breath method was used to measure lung diffusing capacity for carbon monoxide (DL) and one-way repeated measures ANOVA was utilized to evaluate the statistical analysis. Basal values of DL were higher than normal for their age and height (33.6±4.9 mL·min·mmHg; 139±19%) and there were a significant interaction between DL and AS training (ŋ =0.547). After the apnoeic swimming (mid-training) there was an increase in DL from basal to 36.7±7.3 mL·min·mmHg (p=0.021), and after the figures and choreography (post-training) there was a decrease compared to mid-training (32.3±4.6 mL·min·mmHg, p=0.013). Lung diffusing capacity changes occur during AS training, including a large increase after apnoeic swimming. There were no differences in lung diffusing capacity from pre- to post-training, although large inter-individual variability was observed.
艺术游泳运动员（AS）在高强度运动中会在水中反复进行憋气，这会引发他们对训练、憋气和浸水的特殊生理反应。本研究旨在评估在结合憋气游泳、造型和编舞的综合训练中，AS 运动员在训练前、中、后肺弥散能力的变化。来自西班牙国家队的 11 名精英女性 AS 运动员参加了这项研究。采用单次呼吸法测量一氧化碳的肺弥散量（DL），并采用单向重复测量 ANOVA 进行统计分析评估。DL 的基础值高于其年龄和身高的正常水平（33.6±4.9mL·min·mmHg；139±19%），并且 DL 与 AS 训练之间存在显著的交互作用（ŋ=0.547）。在进行憋气游泳（中期训练）后，DL 从基础值增加到 36.7±7.3mL·min·mmHg（p=0.021），而在进行造型和编舞（后期训练）后，DL 与中期训练相比有所下降（32.3±4.6mL·min·mmHg，p=0.013）。在 AS 训练期间，肺弥散能力会发生变化，包括在进行憋气游泳后会大幅增加。虽然存在很大的个体间变异性，但从训练前到训练后，肺弥散能力没有差异。
