Abstract：
Few studies have reported the cardiovascular health effects of different high-intensity interval training (HIIT) protocols among sedentary young women. We investigated the impact of a traditional HIIT programme and a high-intensity circuit training (HICT) programme on lipid profiles and inflammatory cytokine levels in sedentary young women. Forty-two women were randomly assigned to HICT (body weight-based training), HIIT (cycling-based training), or control groups (n = 14 each). HICT and HIIT participants completed an 8-week training programme of three sessions per week. Total cholesterol (TC), triglyceride, high- and low-density lipoprotein, leptin, resistin, tumour necrosis factor-alpha (TNF-α), interleukin-8, and interferon-gamma levels were measured before and after the intervention. Post-intervention, TC and leptin were decreased in the HICT group. The HICT group also demonstrated increased lean mass, upper and lower limb strength, and balance, while the HIIT group displayed improved lower limb strength. Additionally, the control group showed significant increases in triglyceride levels, weight, body mass index, and fat mass. In conclusion, although both HICT and HIIT interventions showed improvements in cardiovascular health and physical fitness, participants in the HICT group experienced more health benefits.
摘要：
很少有研究报道久坐的年轻女性中不同的高强度间歇训练（HIIT）方案对心血管健康的影响。我们调查了传统的HIIT计划和高强度电路训练（HICT）计划对久坐的年轻女性的血脂和炎性细胞因子水平的影响。42名妇女被随机分配到HICT（基于体重的训练），HIIT（基于自行车的训练），或对照组(每组n=14)。HICT和HIIT参与者完成了为期8周的培训计划，每周进行3次培训。总胆固醇(TC),甘油三酯，高密度和低密度脂蛋白，瘦素,抵抗素,肿瘤坏死因子-α（TNF-α），在干预前后测定白细胞介素-8和干扰素-γ水平.干预后，TC和瘦素在HICT组降低。HICT小组还显示出瘦体重增加，上肢和下肢力量，和平衡，而HIIT组显示下肢力量改善。此外,对照组甘油三酯水平显着增加，体重,身体质量指数,和脂肪量。总之,尽管HICT和HIIT干预措施均显示心血管健康和身体健康有所改善，HICT组的参与者体验到更多的健康益处.
