Obesity-induced inflammatory changes in white adipose tissue (WAT), which caused dysregulated expression of inflammation-related adipokines involving tumor necrosis factor-αand monocyte chemoattractant protein-1, contribute to the development of insulin resistance. Moreover, current literature reports state that WAT generates reactive oxygen species (ROS), and the enhanced production of ROS in obese WAT has been closely associated with the dysregulated expression of adipokines in WAT. Therefore, the reduction in excess WAT and oxidative stress that results from obesity is thought to be one of the important strategies in preventing and improving lifestyle-related diseases. Exercise training (TR) not only brings about a decrease in WAT mass but also attenuates obesity-induced dysregulated expression of the adipokines in WAT. Furthermore, some reports indicate that TR affects the generation of oxidative stress in WAT. This review outlines the impact of TR on the expression of inflammation-related adipokines and oxidative stress in WAT.

Rodent studies have indicated that physical exercise may improve adipose tissue function. We investigated the effects of a 12-wk supervised, progressive exercise training program on adipocyte morphology and abdominal subcutaneous adipose tissue function in metabolically well-phenotyped subjects with obesity. Men with obesity ( n = 21) participated in a 12-wk supervised, progressive, combined exercise training program consisting of aerobic exercise (30 min at 70% of maximal power output 2 times/wk) and resistance exercise (3 × 10 repetitions at 60% of 1 repeated maximum 1 time/wk), with adjustment of exercise intensity every 4 wk. At baseline and after intervention, abdominal subcutaneous adipose tissue biopsies were collected to determine 1) adipocyte morphology, 2) gene expression of markers for lipolysis, inflammation, browning, adipokines, and mitochondrial biogenesis/function, 3) protein expression of mitochondrial oxidative phosphorylation (OXPHOS) complexes, and 4) ex vivo basal and β2-adrenergic stimulated lipolysis. The exercise training program, which increased maximal aerobic capacity ( P < 0.001) and muscle strength ( P < 0.001), slightly reduced adipose tissue mass (~0.7 kg, P = 0.021) but did not affect abdominal subcutaneous adipocyte size ( P = 0.744), adipose tissue gene expression of markers for mitochondrial biogenesis and function, browning, lipolysis, inflammation and adipokines, total OXPHOS protein content ( P = 0.789), or β2-adrenergic sensitivity of lipolysis ( P = 0.555). A 12-wk supervised, progressive exercise training program did not alter abdominal subcutaneous adipocyte morphology and adipose tissue gene/protein expression of markers related to adipose tissue function or β2-adrenergic sensitivity of lipolysis in male subjects with obesity.NEW & NOTEWORTHY Studies that investigated the effects of exercise training on adipose tissue function in well-phenotyped humans are scarce. We demonstrate that 12 wk of supervised exercise training improved physical fitness and peripheral insulin sensitivity but did not alter abdominal subcutaneous adipocyte morphology, adipose tissue gene and protein expression of markers related to adipose tissue function, or β2-adrenergic receptor-mediated lipolysis in men with obesity. A prolonged and/or more intense training program may be required to improve human adipose tissue function.
