This study investigated the effect of supervised sprint interval training (SIT) on different cardiometabolic risk factors and adipokines in adolescent boys with obesity. Thirty-seven boys were allocated to either a SIT group (13.1 ± 0.3 years; body mass index [BMI]: 30.3 ± 0.9 kg·m) or a control group (CONT) (13.7 ± 0.4 years; BMI: 32.6 ± 1.6 kg·m). The SIT group performed 4-6 × 30 s all-out cycling sprints, interspersed with 4 min rest, for 3 sessions/week, during a 12-week period, while the non-exercising CONT group maintained a habitual lifestyle. Anthropometric measurements, triglycerides, fasting insulin and glucose, total cholesterol (TC), high- (HDLc) and low-density (LDLc) cholesterol, leptin and adiponectin in blood, cardiorespiratory fitness (CRF), and a metabolic syndrome severity risk score (MSSS) were calculated before and after the 12-week period. Compared to baseline values, a significant reduction in MSSS was seen in the SIT group after intervention. LDLc showed favorable changes in SIT compared to CONT (-0.06 ± 0.1 vs. 0.19 ± 0.01 mmol·L; = 0.025). Additionally, CRF increased in the SIT group compared to the CONT group (5.2 ± 1.1 vs. -2.1 ± 1.1 mL·min·kg, < 0.001). Moreover, a 12-week all-out SIT training effectively improves cardiometabolic health in adolescent boys with obesity.
这项研究调查了监督式冲刺间歇训练（SIT）对肥胖青少年男孩的不同心血管代谢风险因素和脂肪因子的影响。37 名男孩被分配到 SIT 组（13.1 ± 0.3 岁；体重指数 [BMI]：30.3 ± 0.9 kg·m）或对照组（CONT）（13.7 ± 0.4 岁；BMI：32.6 ± 1.6 kg·m）。SIT 组在 12 周期间每周进行 3 次，每次进行 4-6 次 30 秒的全力自行车冲刺，每次冲刺之间休息 4 分钟。非运动的 CONT 组保持习惯的生活方式。在 12 周后，测量了人体测量学指标、甘油三酯、空腹胰岛素和血糖、总胆固醇（TC）、高（HDLc）和低（LDLc）密度胆固醇、血液中的瘦素和脂联素、心肺适能（CRF）和代谢综合征严重程度风险评分（MSSS）。与基线值相比，SIT 组在干预后 MSSS 显著降低。与 CONT 组相比，SIT 组的 LDLc 发生了有利的变化（-0.06 ± 0.1 对 0.19 ± 0.01 mmol·L； = 0.025）。此外，与 CONT 组相比，SIT 组的 CRF 增加（5.2 ± 1.1 对-2.1 ± 1.1 mL·min·kg， < 0.001）。此外，12 周的全力 SIT 训练可有效改善肥胖青少年男孩的心血管代谢健康。
