Our study examined the effect of 8 weeks of high-intensity interval training (HIIT) and spirulina supplementation on the humoral immunity, cardio-respiratory fitness, and body composition of overweight and obese women. Thirty sedentary women (height: 161.7 ± 2.8 cm, body mass: 75.8 ± 8.4 kg, body mass index [BMI]: 28.8 ± 2.5 kg/m, age: 25.1 ± 6.7 years) were divided into three groups: placebo with HIIT group, spirulina group (SG), or combined group (CG). Exercise groups performed HIIT for 8 weeks, with three sessions per week and four to seven repetitions in each session of 30 s running and 30 s walking; the intensity was established at 90% of the maximum heart rate. Supplementation groups received 6 g of spirulina powder per day. Fasting blood samples were collected before and after 8 weeks to determine the concentrations of immunoglobulins (IgA and IgG). There was a significant group-by-time interaction for fat free mass (FFM; = 0.001, f = 8.52, ηp = 0.39) and IgA ( = 0.036, f = 3.86, ηp = 0.22). The post hoc analysis revealed that CG reduced FFM significantly ( = 0.012, = -0.55) after training. CG and SG showed significantly greater IgA concentrations after 8 weeks ( = 0.02, = 0.70 and = 0.001, = 0.34, respectively). We conclude that spirulina supplementation with HIIT affects the body composition (lower FFM) but also boosts IgA, which plays an important role in the immune system.
我们的研究考察了为期8周的高强度间歇训练（HIIT）和补充螺旋藻对超重及肥胖女性体液免疫、心肺适能和身体成分的影响。30名久坐不动的女性（身高：161.7±2.8厘米，体重：75.8±8.4千克，体重指数[BMI]：28.8±2.5千克/平方米，年龄：25.1±6.7岁）被分为三组：HIIT加安慰剂组、螺旋藻组（SG）或联合组（CG）。运动组进行8周的HIIT，每周三次，每次训练包含4至7组30秒跑步和30秒步行；强度设定为最大心率的90%。补充组每天服用6克螺旋藻粉。在8周前后采集空腹血样，以测定免疫球蛋白（IgA和IgG）的浓度。无脂肪量（FFM；F = 0.001，f = 8.52，ηp = 0.39）和IgA（F = 0.036，f = 3.86，ηp = 0.22）存在显著的组×时间交互作用。事后分析显示，训练后CG组的FFM显著降低（p = 0.012，d = -0.55）。8周后，CG组和SG组的IgA浓度显著升高（分别为p = 0.02，d = 0.70和p = 0.001，d = 0.34）。我们得出结论，HIIT联合补充螺旋藻会影响身体成分（降低FFM），但也会提高IgA水平，而IgA在免疫系统中起重要作用。
