■进行这项研究是为了评估高强度间歇训练(HIIT)对黄斑微循环的影响,通过扫频源光学相干断层扫描血管造影(SSOCTA)对年轻足球运动员进行测量。
■包括18-20岁的足球运动员。经过详细的眼科检查,生理参数,包括高度,体重,身体脂肪,全身血压,血细胞比容值,氧饱和度,和心率,被记录下来。使用DRIOCTTriton(Topcon,东京,日本)上午11:00至下午1:00之间。
■15名参与者完成了研究。全部为男性,平均年龄为18.1±0.4岁。收缩压、舒张压、血氧饱和度无明显变化(P>0.05)。而HIIT程序后血细胞比容水平显着增加(P=0.049)。心率和眼压降低(P=0.003,P=0.017)。深毛细血管丛中心血管密度明显增加(前:18.7±3.8%,后:21.1±4.5%)和脉络膜毛细血管中心血管密度(前:54.5±2.8%,后56.9±2.2%)(分别为P=0.02,P=0.02),尽管在其他ssOCTA或中央黄斑厚度和中央凹下脉络膜厚度中未观察到变化。
■6周,每周进行三次锻炼的高强度间歇训练计划似乎不会改变平均浅表血管密度,深中央凹无血管区,和浅表中央凹无血管区,黄斑中心厚度,或中央凹下脉络膜厚度,而中心深血管密度和中心脉络膜毛细血管密度在ssOCTA参数中显著增加。
UNASSIGNED: This study was conducted to evaluate the effect of high intensity interval training (HIIT) on macular microcirculation, measured by swept source optical coherence tomography angiography (ss OCTA) in young football players.
UNASSIGNED: Football players between 18-20 years old were included. After a detailed ophthalmological examination, physiological parameters, including height, body weight, body fat, systemic blood pressure, hematocrit values, oxygen saturation, and heart rate, were recorded. Intraocular pressure and ss OCTA parameters were measured one day before and the day after the high intensity interval training program using DRI OCT Triton (Topcon, Tokyo, Japan) between 11:00 am and 1:00 pm.
UNASSIGNED: Fifteen participants completed the study. All were males with a mean age of 18.1 ± 0.4 years. Systolic and diastolic blood pressure and oxygen saturation did not change significantly (P > 0.05), while hematocrit levels increased remarkably (P = 0.049) after the HIIT program. Heart rates and intraocular pressure decreased (P = 0.003, P = 0.017, respectively). There was a significant increase in the central vessel density in deep capillary plexus (before: 18.7 ± 3.8%, after: 21.1 ± 4.5%) and central vessel density in choriocapillaris (before: 54.5 ± 2.8%, after 56.9 ± 2.2%) (P = 0.02, P = 0.02, respectively), although no changes were observed in other ss OCTA or in the central macular thickness and subfoveal choroidal thickness.
UNASSIGNED: A 6 week, high intensity interval training program with three exercise sessions per week seems not to alter mean superficial vascular densities, deep foveal avascular zone, and superficial foveal avascular zones, central macular thickness, or subfoveal choroidal thickness, while the central deep vascular density and central choriocapillaris vascular density increased remarkably among ss OCTA parameters.
