: Individuals with abdominal obesity and metabolic syndrome (MetS) have augmented risk of all-cause mortality. Lifestyle interventions are effective to treat MetS, however, there are periods during the year in which exercise programs are discontinued and improper dietary habits reappear (e.g., Christmas holidays). We aimed to analyze if exercise-training during Christmas holidays would avoid body-weight gains and cardiometabolic deterioration in MetS individuals, using a randomized control trial. Thirty-eight men with MetS undergoing exercise training were randomly allocated to either continue (TRAIN group, n = 16) or discontinue (HOLID group, n = 22) training, during the three weeks of Christmas. Anthropometrics (body weight, fat, and waist circumference), fasting blood metabolites (glucose, insulin, triglycerides, and cholesterol concentrations) and exercise maximal fat oxidation (FO_MAX) and oxygen uptake (VO_2PEAK) were determined before and after Christmas. Both groups were similar at baseline in all parameters (p > 0.05). HOLID group increased body weight (91.3 ± 13.0 to 92.0 ± 13.4 kg, p = 0.004), mean arterial pressure (94.0 ± 10.6 to 97.1 ± 8.9 mmHg, p = 0.026), blood insulin (10.2 ± 3.8 to 12.5 ± 5.4 µIU·mL⁻¹, p = 0.003) and HOMA (3.2 ± 1.3 to 4.1 ± 2.3, p = 0.003). In contrast, TRAIN prevented those disarrangements and reduced total (170.6 ± 30.6 to 161.3 ± 31.3 mg·dL⁻¹, p = 0.026) and low-density lipoprotein cholesterol (i.e., LDL-_C, 104.8 ± 26.1 to 95.6 ± 21.7 mg·dL⁻¹, p = 0.013). TRAIN also prevented the reductions in exercise FO_MAX and VO_2PEAK that was observed in the HOLID group (p = 0.002). In conclusion, exercise training during Christmas, prevents body weight gains and the associated cardiovascular (increase in blood pressure and LDL_-C) and metabolic (reduced insulin sensitivity) health risks are an optimal non-pharmacological therapy for that period of the year.

圣诞节期间进行运动训练对超重个体体重和心脏代谢健康的影响。

： 患有腹部肥胖和代谢综合征（MetS）的人增加了全因死亡率的风险。生活方式干预可以有效治疗MetS，但是，一年中的某些时段，运动计划会中断，并且饮食习惯会重新出现（例如圣诞节假期）。我们旨在通过一项随机对照试验来分析圣诞节假期期间的运动训练是否可以避免MetS个体的体重增加和心脏代谢恶化。在圣诞节的三周内，将38名接受运动训练的MetS男性随机分配为继续训练（TRAIN组，n = 16）或停止训练（HOLID组，n = 22）。人体测量学（体重，脂肪和腰围），空腹血液代谢产物（葡萄糖，胰岛素，甘油三酸酯，在圣诞节前后确定了_MAX）和摄氧量（VO _2PEAK）。两组的所有参数在基线时均相似（p > 0.05）。HOLID组体重增加（91.3±13.0至92.0±13.4 kg，p = 0.004），平均动脉压（94.0±10.6至97.1±8.9 mmHg，p = 0.026），血液胰岛素（10.2±3.8至12.5±5.4 µIU· mL ^-1，p＝ 0.003）和HOMA（3.2±1.3至4.1±2.3，p＝ 0.003）。相反，TRAIN可以防止这些紊乱并减少总胆固醇（170.6±30.6至161.3±31.3 mg·dL ^-1，p = 0.026）和低密度脂蛋白胆固醇（即LDL- _C，104.8±26.1至95.6±21.7mg·dL ^-1，p＝ 0.013）。火车还阻止了在HOLID组中观察到的运动FO _MAX和VO _2PEAK的降低（p = 0.002）。总之，圣诞节期间的运动训练可防止体重增加，并且相关的心血管疾病（血压和LDL _-C升高）和代谢（胰岛素敏感性降低）健康风险是一年中该时期的最佳非药物疗法。
