Respiratory function decline has been reported mainly in the morbidly obese. Little is known about the influence of adiposity pattern on the ability to generate strength in respiratory muscles. This study evaluated strength and respiratory endurance in the morbidly obese in preoperative bariatric surgery to determine if such variables were affected by different anthropometric markers (body mass index (BMI), waist-hip ratio (WHR), and neck circumference (NC)).
We evaluated 39 adult and young obese patients of both sexes, with no respiratory or heart diseases. Standard pulmonary function tests and static respiratory muscle strength (maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP)) and endurance (maximum voluntary ventilation (MVV)) were measured in relation to sex and groups (WHR > 0.95 and WHR < 0.95; NC > 43 and NC < 43).
Thirty-nine obese patients (28 women), aged 36.9 + 11.9 years, BMI 49.3 + 5.1 kg/m², WHR 0.96 + 0.07, and NC 44.1 + 4.2 cm, took part in the study Standard pulmonary function tests and respiratory muscle strength were within normal parameters, except MVV (<80%). Obese with NC ≥ 43 cm (n = 22) have greater respiratory muscle strength and less endurance, MEP (p = 0.031) and MVV (p = 0.018). Abdominal adiposity (n = 19) does not seem to affect respiratory muscle strength. A positive correlation was observed only between NC and PEF (r = 0.392, p = 0.014) and marginally between NC and MVV (r = 0.308, p = 0.056).
Although adiposity patterns did not affect inspiratory muscle strength, neck adiposity was associated lower respiratory muscle endurance.
呼吸功能下降主要在病态肥胖者中报道。关于体脂分布模式对呼吸肌产生力量的能力的影响知之甚少。本研究评估了术前减重手术中病态肥胖患者的力量和呼吸耐力，以确定这些变量是否受不同的人体测量标志物（体重指数（BMI）、腰臀比（WHR）和颈围（NC））的影响。
我们评估了 39 名成年和年轻的肥胖男女患者，无呼吸或心脏疾病。测量了标准肺功能测试以及静态呼吸肌肉力量（最大吸气压力（MIP）和最大呼气压力（MEP））和耐力（最大自主通气量（MVV）），并与性别和组（WHR>0.95 和 WHR<0.95；NC>43 和 NC<43）相关。
39 名肥胖患者（28 名女性），年龄 36.9 + 11.9 岁，BMI 49.3 + 5.1 kg/m²，WHR 0.96 + 0.07，NC 44.1 + 4.2 cm，参加了研究。标准肺功能测试和呼吸肌肉力量均在正常范围内，除 MVV（<80%）外。NC≥43 cm（n = 22）的肥胖者呼吸肌肉力量较大，耐力较低，MEP（p = 0.031）和 MVV（p = 0.018）。腹部肥胖（n = 19）似乎不会影响呼吸肌肉力量。仅观察到 NC 与 PEF 之间存在正相关（r = 0.392，p = 0.014），NC 与 MVV 之间存在边缘相关（r = 0.308，p = 0.056）。
尽管体脂分布模式不影响吸气肌力量，但颈脂与较低的呼吸肌耐力有关。
