背景:近年来,青少年心血管疾病变得更加严重。高强度间歇训练(HIIT)和中等强度连续训练(MICT)已被证明可以改善青少年的心血管疾病。采用Meta分析比较HIIT和MICT对青少年心血管危险因素的影响。
方法:使用CNKI等权威数据库检索截至2023年1月青少年心血管危险因素的HIIT和MICT随机对照试验,WebofScience,PubMed,和EBSCO。使用ReviewManage5.4和Stata14.0进行数据分析。
结果:共有12项研究,涉及468名参与者,平均年龄15.19±4.35被纳入研究.研究结果表明,与MICT相比,HIIT降低了青少年体重(SMD=-0.18,95CI=-0.58,0.21),增加了最大摄氧量(SMD=0.56,95CI=0.20,0.93)和高密度脂蛋白(SMD=-0.47,95%CI=-1.11,0.17),收缩压改善(SMD=-0.35,95CI=-0.78,0.09),葡萄糖(SMD=-1.53,95CI=-2.93,-0.13),和胰岛素(SMD=-0.66,95%CI=-1.73,0.41),p<0.05。HIIT和MICT改善了BMI,脂肪量,舒张压,甘油三酯,总胆固醇,LDL,这些训练类型之间没有显着差异。
结论:HIIT在改善青少年心血管健康方面优于MICT,对体重有更好的影响,BMI,脂肪量,收缩压,舒张压,最大摄氧量,甘油三酯,总胆固醇,LDL,HDL,葡萄糖,和胰岛素水平。
BACKGROUND: In recent years, cardiovascular diseases in adolescents have become more serious. High intensity interval training (HIIT) and moderate intensity continuous training (
MICT) have been shown to improve cardiovascular diseases in adolescents. Meta-analysis was conducted to compare the effects of HIIT and
MICT on cardiovascular risk factors in adolescents.
METHODS: Randomised controlled trials of HIIT and
MICT for cardiovascular risk factors in adolescents up to January 2023 were searched using authoritative databases such as CNKI, Web of Science, PubMed, and EBSCO. Data analysis was performed using Review Manage 5.4 and Stata 14.0.
RESULTS: A total of 12 studies involving 468 participants, mean age 15.19±4.35, were included in the study. The findings showed that compared with
MICT, HIIT reduced adolescents\' body weight (SMD=-0.18, 95 %CI=-0.58, 0.21) and increased maximal oxygen uptake (SMD=0.56, 95 %CI=0.20, 0.93) and high-density lipoprotein (SMD=-0.47, 95 % CI=-1.11, 0.17), and improved systolic blood pressure (SMD=-0.35, 95 %CI=-0.78, 0.09), glucose (SMD=-1.53, 95 %CI=-2.93, -0.13), and insulin (SMD=-0.66, 95 % CI=-1.73, 0.41), p<0.05. HIIT and
MICT improved BMI, fat mass, diastolic blood pressure, triglycerides, total cholesterol, and LDL, with no significant difference between these training types.
CONCLUSIONS: HIIT was better than MICT for improving cardiovascular health in adolescents, with better effects on body weight, BMI, fat mass, systolic blood pressure, diastolic blood pressure, maximal oxygen uptake, triglyceride, total cholesterol, LDL, HDL, glucose, and insulin levels.
