The purpose of this study was to compare a specific graded exercise test using deep-water running (DWR) with a cycle ergometry (CE) test on land to develop an equation to estimate aerobic threshold for training in DWR in patients with chronic nonspecific low back pain.
This is a cross-sectional study of 23 subjects with chronic nonspecific low back pain. Maximal and submaximal heart rates (HR), blood lactate, and rating of perceived exertion in the aquatic and land-based graded exercise tests were investigated.
The results suggest that both tests were undertaken at maximal intensity. DWR maximal HR was lower (-12%) than that in the CE test. For both tests, the maximal rating of perceived exertion was greater than 18, and maximum blood lactate was 8 mmol/l, with no significant difference between the CE and DWR tests. The lineal regression for estimate aerobic threshold for training in DWR in persons with chronic nonspecific low back pain was as follows: maximal HR DWR = 136.9 + (age × -0.544) + (maximal HR CE + 0.285). The correlation between maximal HR during DWT and CE tests was 0.538 (P = 0.008).
A graded DWR test can be used as an alternative in the assessment of aerobic fitness in chronic nonspecific low back pain.
本研究旨在比较使用深水区跑步（DWR）的特定分级运动试验和陆地自行车测力计（CE）试验，以制定用于估计慢性非特异性下腰痛患者 DWR 训练的有氧阈值的方程。
这是一项对 23 例慢性非特异性下腰痛患者的横断面研究。在水基和陆基分级运动试验中，研究了最大和次最大心率（HR）、血乳酸和感知用力程度。
结果表明，两项测试均以最大强度进行。DWR 最大 HR 比 CE 测试低（-12%）。对于两项测试，最大感知用力程度均大于 18，最大血乳酸为 8mmol/L，CE 和 DWR 测试之间无显著差异。用于估计慢性非特异性下腰痛患者 DWR 训练的有氧阈值的线性回归方程如下：最大 DWR HR = 136.9 +（年龄×-0.544）+（CE 最大 HR + 0.285）。DWT 和 CE 测试期间最大 HR 的相关性为 0.538（P = 0.008）。
分级 DWR 试验可作为慢性非特异性下腰痛患者有氧健身评估的替代方法。
