To compare the effects of 12 weeks of high-intensity interval training (HIIT) versus moderate-intensity interval training (MIIT) on hematological and inflammatory markers in youth females, 38 overweight/obese females (16.4±1.0 yrs.) were randomly assigned to HIIT (2×6-8 repetitions of 30 s at 100-110% maximal aerobic speed (MAS), with 30 s active recovery between repetitions at 50% MAS; n=13), MIIT (2×6-8 repetitions of 30 s at 70-80% MAS, with 30 s active recovery between repetitions at 50% MAS; n=13), and a control group (CG, no intervention; n=12). Body composition, blood pressure, maximal heart rate, hematological and inflammatory markers (C-reactive protein [CRP], and erythrocyte sedimentation rate [ESR]) markers were assessed in all groups before and following the training program. Results revealed a significant (P<0.05) interaction effect for body composition, systolic blood pressure (SBP), MAS, maximal heart rate, and CRP. Within-group analyses for the HIIT and MIIT groups showed significant improvements in body mass (P=0.009 and P=0.025, respectively), BMI Z-score (P=0.011 and P=0.028, respectively), and MAS (P<0.001 and P=0.011, respectively). The HIIT program showed a significant decrease in body fat (P=0.002), waist circumference (P=0.002), maximal heart rate (P=0.003), SBP (P=0.001), and plasma CRP (P=0.004). In both groups, no significant changes were observed in ESR and hematological markers after intervention. No variable changed in CG. HIIT was the effective method to manage cardiometabolic health and inflammatory disorders in obese youth.
为比较12周高强度间歇训练（HIIT）与中等强度间歇训练（MIIT）对青年女性血液学和炎症标志物的影响，将38名超重/肥胖女性（16.4±1.0岁）随机分为HIIT组（以最大有氧速度（MAS）的100 - 110%进行2组，每组30秒，重复6 - 8次，组间以MAS的50%进行30秒主动恢复；n = 13）、MIIT组（以MAS的70 - 80%进行2组，每组30秒，重复6 - 8次，组间以MAS的50%进行30秒主动恢复；n = 13）和对照组（CG，无干预；n = 12）。在训练计划前后对所有组的身体成分、血压、最大心率、血液学和炎症标志物（C反应蛋白[CRP]和红细胞沉降率[ESR]）进行评估。结果显示，在身体成分、收缩压（SBP）、MAS、最大心率和CRP方面存在显著（P<0.05）交互作用。HIIT组和MIIT组的组内分析显示，体重（分别为P = 0.009和P = 0.025）、BMI Z评分（分别为P = 0.011和P = 0.028）以及MAS（分别为P<0.001和P = 0.011）有显著改善。HIIT训练计划使体脂（P = 0.002）、腰围（P = 0.002）、最大心率（P = 0.003）、SBP（P = 0.001）和血浆CRP（P = 0.004）显著降低。两组干预后ESR和血液学标志物均无显著变化。CG组各变量均无变化。HIIT是管理肥胖青年心脏代谢健康和炎症性疾病的有效方法。
