水下近红外光谱（uNIRS）设备的发展使以前无法实现的测量外周肌肉血流动力学和氧合在自然水生环境中进行。本研究的目的是（i）在真实的训练研究中试用uNIRS，（ii）监测游泳训练计划对短距离游泳中肌肉氧合状态的影响。共有14名青少年俱乐部水平的游泳运动员在为期八周的耐力训练计划前后完成了重复的游泳冲刺测试。将防水便携式近红外光谱仪连接到股外侧肌。uNIRS成功地测量了所有个体的肌肉氧合和血容量的变化;该设备的快速亚秒级时间分辨率能够证明在特征游泳运动期间的肌肉氧合变化。训练后的心率恢复和游泳表现时间显着改善。uNIRS数据也显示出显着变化。在个人短跑期间，脱氧血红蛋白的较大幅度上升表明训练引起了肌肉氧提取的增加;肌肉氧合的更快恢复时间表明了积极的训练引起的变化，肌肉血流量也发生了显着变化。由于在增加的复氧率和改善的游泳表现时间之间观察到强相关性，这些发现支持使用uNIRS作为游泳中的新的表现分析工具。
The development of an underwater near-infrared spectroscopy (uNIRS) device has enabled previously unattainable measurements of peripheral muscle hemodynamics and oxygenation to be taken within the natural aquatic environment. The purposes of this study were (i) to trial the use of uNIRS, in a real world training study, and (ii) to monitor the effects of a swim training program upon muscle oxygenation status in short distance swimming. A total of 14 junior club level swimmers completed a repeated swim sprint test before and after an eight week endurance training program. A waterproof, portable Near-Infrared Spectroscopy device was attached to the vastus lateralis. uNIRS successfully measured changes in muscle oxygenation and blood volume in all individuals; rapid sub-second time resolution of the device was able to demonstrate muscle oxygenation changes during the characteristic swim movements. Post training heart rate recovery and swim performance time were significantly improved. uNIRS data also showed significant changes. A larger rise in deoxyhemoglobin during individual sprints suggested training induced an increase in muscle oxygen extraction; a faster recovery time for muscle oxygenation suggested positive training induced changes and significant changes in muscle blood flow also occur. As a strong correlation was seen between an increased reoxygenation rate and an improved swim performance time, these findings support the use of uNIRS as a new performance analysis tool in swimming.
