方法：测定运动量对运动员运动能力的影响（每节千卡）和强度（最大耗氧量百分比[% VO（2）峰值]）对腹部肥胖成人脂肪组织（AT）和骨骼肌（SM）的影响。（n=103; 52.7 ± 7.6岁）被随机分为以下组：对照组;低量低强度运动（50%VO（2）峰值时，180 kcal/次[女性]和300 kcal/次[男性]）;高量、低强度运动（HALI; 360 kcal/session [女性]和600 kcal/session [男性]在50%VO（2）峰值）;或高量，高强度运动（HAHI; 360 kcal/session [女性]和600 kcal/session [男性]在75%VO（2）峰值）24周。通过加速度计测量日常生活活动。磁共振成像被用来测量组织mass.ResultsConclusionsReduction在所有AT仓库是更大的运动组与对照组相比（P0.05）。内脏和腹部皮下AT减少在整个腹部是均匀的。与对照组相比，运动后SM总质量没有变化（P=0.32）。高剂量高强度组和高剂量低强度组在保持下半身SM质量的同时，上半身SM质量较对照组减少（P
ObjectiveMethodsTo determine the effects of exercise amount (kilocalories per session) and intensity (percent of maximal oxygen consumption [% VO(2)peak]) on adipose tissue (AT) and skeletal muscle (SM) in adults with abdominal obesity.Participants (n=103; 52.77.6 years) were randomized to the following groups: control; low-amount, low-intensity exercise (180 kcal/session [women] and 300 kcal/session [men] at 50% VO(2)peak); high-amount, low-intensity exercise (HALI; 360 kcal/session [women] and 600 kcal/session [men] at 50% VO(2)peak); or high-amount, high-intensity exercise (HAHI; 360 kcal/session [women] and 600 kcal/session [men] at 75% VO(2)peak) for 24 weeks. Activities of daily living were measured by accelerometry. Magnetic resonance imaging was used to measure tissue mass.ResultsConclusionsReduction in all AT depots was greater in the exercise groups compared with control (P0.05). Visceral and abdominal subcutaneous AT reduction was uniform across the abdomen. Total SM mass did not change with exercise compared with control (P=0.32). However, while lower-body SM mass was maintained (P=0.32), upper-body SM mass in the high-amount, high-intensity and the high-amount, low-intensity groups was reduced compared with controls (P
