Abstract

Background: Obesity among adolescents is rising, raising concerns about future cardiopulmonary disease. It's unclear if this group has impaired cardiopulmonary function and whether this stems from muscle issues or sedentary behavior.

Methods: This cross-sectional study compared obese/overweight (n = 29) and non-obese (n = 29) adolescents (age ~ 21 yrs). It assessed cardiopulmonary function, axial rotation, muscle quality / quantity (respiratory, abdominal, gluteal), and outdoor activity.

Results: Non-obese females had significantly more weekly outdoor activities. Cardiopulmonary results showed mixed findings: the obese group had higher maximum voluntary ventilation (MVV) and peak heart rate (HRpeak), while the non-obese group had better resting heart rate (HRrest) and oxygen consumption per kilogram (VO2/kg). The obese group had thicker sternocleidomastoid, rectus abdominis (RA), and gluteal muscles, but poorer muscle quality (ultrasound grayscale) in the upper trapezius and RA compared to the non-obese group. In obese females, higher VO2/kg correlated with better RA quality, while higher peak VO2 correlated with less outdoor activity time. Muscle imbalance was only seen in non-obese females and was positively associated with activity levels.

Conclusion: In comparison to non-obese peers, obese/overweight adolescents show inferior cardiopulmonary function and reduced muscle performance. While some muscles are thicker in the obese group, lower grayscale values indicate poor quality/function. Muscle assessment should not rely solely on thickness. Although outdoor activity shows a positive correlation with some cardiopulmonary parameters, muscle metabolic issues related to sedentary behavior likely represent a significant correlate of cardiopulmonary dysfunction.

超声特征与户外活动对肥胖青少年的影响：一项横断面心肺研究。

背景：青少年肥胖正在上升，这引起了人们对未来心肺疾病的关注。目前还不清楚这组人是否心肺功能受损，以及这是由肌肉问题还是久坐行为引起的。方法：本横断面研究比较肥胖/超重（n = 29）和非肥胖（n = 29）青少年（年龄~ 21岁）。它评估了心肺功能、轴向旋转、肌肉质量/数量（呼吸、腹部、臀肌）和户外活动。结果：非肥胖女性每周的户外活动显著增加。心肺结果显示混合结果：肥胖组有更高的最大自主通气量（MVV）和峰值心率（HRpeak），而非肥胖组有更好的静息心率（HRrest）和每公斤耗氧量（VO2/kg）。肥胖组胸锁乳突肌、腹直肌（RA）和臀肌较厚，但与非肥胖组相比，上斜方肌和RA的肌肉质量（超声灰度）较差。在肥胖女性中，较高的VO2/kg与较好的RA质量相关，而较高的峰值VO2与较少的户外活动时间相关。肌肉失衡只在非肥胖女性中出现，并且与运动水平呈正相关。结论：与非肥胖同龄人相比，肥胖/超重青少年心肺功能较差，肌肉功能下降。虽然肥胖组的某些肌肉较厚，但灰度值较低表明质量/功能较差。肌肉评估不应该仅仅依赖于厚度。尽管户外活动与一些心肺参数呈正相关，但与久坐行为相关的肌肉代谢问题可能是心肺功能障碍的重要相关因素。

期刊介绍： Nutrition & Metabolism publishes studies with a clear focus on nutrition and metabolism with applications ranging from nutrition needs, exercise physiology, clinical and population studies, as well as the underlying mechanisms in these aspects. The areas of interest for Nutrition & Metabolism encompass studies in molecular nutrition in the context of obesity, diabetes, lipedemias, metabolic syndrome and exercise physiology. Manuscripts related to molecular, cellular and human metabolism, nutrient sensing and nutrient–gene interactions are also in interest, as are submissions that have employed new and innovative strategies like metabolomics/lipidomics or other omic-based biomarkers to predict nutritional status and metabolic diseases. Key areas we wish to encourage submissions from include: -how diet and specific nutrients interact with genes, proteins or metabolites to influence metabolic phenotypes and disease outcomes; -the role of epigenetic factors and the microbiome in the pathogenesis of metabolic diseases and their influence on metabolic responses to diet and food components; -how diet and other environmental factors affect epigenetics and microbiota; the extent to which genetic and nongenetic factors modify personal metabolic responses to diet and food compositions and the mechanisms involved; -how specific biologic networks and nutrient sensing mechanisms attribute to metabolic variability.
