- 运动科学 运动科学
背景情况:
- 新出现的证据表明,体育活动对大脑发育有积极的影响.
- 对身体活动对儿童白质微观结构的影响的研究是有限的.
- 需要精心设计的随机临床试验来证实这些影响.
研究的目的:
- 评估20周体育活动干预对超重或肥胖儿童全球白质微观结构的影响.
- 为了确定身体活动对白质微观结构的影响是否广泛或特定于某些白质区域.
主要方法:
- 109名超重/肥胖儿童 (8-11岁) 被随机分配到体育活动计划或对照组.
- 扩散张力成像 (DTI) 用于分析白质的特性.
- 用概率纤维通道图和基于通道的空间统计 (TBSS) 来进行数据分析.

507
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...
