Although the effects of sub-maximal continuous aerobic training (SCT) and high-intensity interval training (HIIT) are well studied in performance athletes and in several patient groups, there is not much evidence about the effects of these exercises in sedentary healthy young population. The aim of the study was to compare the effects of these two different types of aerobic exercises on respiratory parameters, aerobic capacity and perceived stress in healthy university students.
Thirty-six healthy, young subjects with a mean age of 20.83±0.97 years were included in the study (N.=19 in HIIT and N.=17 in SCT). Pulmonary function tests (PFTs) and respiratory muscle strength (RMS) assessments were done using a desktop spirometer. Aerobic capacity was estimated with the Bruce treadmill exercise test. The Perceived Stress Scale (PSS) was used for the assessment of stress perception. All participants exercised 3 times per week for 4 weeks (a total of 12 sessions).
After 12 sessions, the peak expiratory flow parameter (a PFT value) of both groups showed significant increases, but there was no difference between the groups. The RMS of the subjects increased significantly in both the groups (P<0.05), but there was no significant difference between the groups. Both groups showed significant increases in terms of aerobic capacity (P>0.05), and the improvement was significantly higher in the HIIT group. Perceived stress values showed a significant increase in the SCT group.
Based on the results of this study, the two exercise types were found to have similar effects on RMS. Also, when compared with SCT, HIIT was found to have more effect on aerobic capacity.
虽然亚最大强度持续有氧训练（SCT）和高强度间歇训练（HIIT）对表现运动员和一些患者群体的效果已经得到了很好的研究，但在久坐的健康年轻人群中，关于这些运动的效果的证据并不多。本研究的目的是比较这两种不同类型的有氧运动对健康大学生呼吸参数、有氧能力和感知压力的影响。
36 名健康的年轻受试者（平均年龄 20.83±0.97 岁）被纳入研究（HIIT 组 N=19，SCT 组 N=17）。使用台式肺活量计进行肺功能测试（PFTs）和呼吸肌力量（RMS）评估。使用 Bruce 跑步机运动测试估计有氧能力。使用感知压力量表（PSS）评估压力感知。所有参与者每周锻炼 3 次，持续 4 周（共 12 次）。
经过 12 次训练后，两组的最大呼气流量参数（PFT 值）均显著增加，但组间无差异。两组受试者的 RMS 均显著增加（P<0.05），但组间无显著差异。两组的有氧能力均显著提高（P>0.05），HIIT 组的改善更为显著。SCT 组的感知压力值显著增加。
根据本研究结果，两种运动类型对 RMS 的影响相似。与 SCT 相比，HIIT 对有氧能力的影响更大。
