我们的目的是比较高强度间歇训练（HIT）与持续适度运动（CME）对健康受试者眼内压（IOP）的急性影响。15名年轻男性（年龄= 22.1 ± 6岁）以随机顺序（两次治疗之间间隔2-5天）接受30分钟HIT（以50%的储备心率（HR）步行2分钟，以80%的储备心率跑步1分钟）和CME治疗（以60%的储备心率慢跑/跑步30分钟）。在每次运动前（基线）、运动后即刻（运动后）、运动后5分钟（Rec 5）和运动后10分钟（Rec 10）测量IOP。在HIT和CME治疗期间，IOP在运动后降低，并在Rec 5时保持降低，干预之间无显著差异（23%与16%相似）。然而，仅在HIT干预后，Rec 10时的IOP保持降低（类似于19%），而Rec 10时的IOP恢复至与CME干预期间基线时观察到的水平相似。总之，HIT和CME在运动后即刻和5分钟同样降低IOP。然而，只有HIT能够在运动后10分钟保持IOP降低。这些结果表明，HIT可能比CME更有效地降低年轻健康男性的IOP。
Our purpose was to compare the acute effects of high-intensity interval training (HIT) vs. continuous moderate exercise (CME) on intraocular pressure (IOP) in healthy subjects. Fifteen young men (age = 22.1 +/- 6 years) underwent 30 min of HIT (2 min of walking at 50 % of reserve heart rate (HR) alternated with 1 min of running at 80 % of reserve HR) and CME sessions (30 min of jogging/running at 60 % of reserve HR) in random order (2-5 days between sessions). IOP was measured before (baseline), immediately after (post-exercise), 5 min after (Rec5) and 10 min after (Rec10) each exercise session. IOP was reduced post-exercise and remained reduced at Rec5 during both HIT and CME session, with no significant difference between interventions (similar to 16 % between 23 %). However, IOP remained reduced at Rec10 only after HIT intervention (similar to 19 %), whereas IOP at Rec10 returned to levels similar to the observed at baseline during CME intervention. In summary, both HIT and CME equally reduced IOP immediately and 5 min after exercise session. However, only HIT was able to remain IOP reduced 10 min after exercise. These results suggest that HIT may be more effective than CME for reducing IOP in young healthy men.
