Exercise training lowers serum chemerin concentration in obese children

Exercise and adiposity in overweight and obese children and adolescents: a systematic review with network meta-analysis of randomised trials

“…Of the 6478 citations screened after removing duplicates both electronically and manually, 57 studies representing 127 groups (73 exercise, 54 control) and 2792 participants (1667 exercise, 1125 control) met the criteria for inclusion 13–40 42–69 98. The number needed to screen was 0.88% while the NNR was 114.…”

“…The included studies were published in 45 different journals since 1997 ( trueX- ± SD = 2011±4, median=2012). Fifty-two studies (91.2%) were published in the English language,13 14 16–18 20 22 24–40 42–69 while the remaining five (8.8%) were published in either Chinese19 21 23 98 or Spanish 15. The location in which studies were conducted included 20 different countries, 12 in the USA,24 30 34 35 39 40 46 48 52 56 60 66 8 in China,19–23 38 61 62 98 6 in Brazil,13 15 45 47 58 63 5 in South Korea,36 37 49 55 59 4 in Tunisia,17 25 50 51 3 each in Australia,54 64 65 Canada14 32 57 and Iran,27 29 69 2 in Turkey,33 53 and 1 each in either France,16 Germany,44 Italy,28 Lebanon,68 New Zealand,42 Norway,18 Singapore,67 Sweden,31 Switzerland,26 Taiwan22 or the UK 43.…”

“…For strength training interventions,14 21 28 35 39 40 47 53 54 56 57 statistically significant decreases were reported for 9.1% (BMI in kg/m 2 ), 25.0% (fat mass) and 63.6% (per cent fat) of findings. Finally, when restricted to combined aerobic and strength training,13 18–21 23 26 27 31 37 45 49 51 57 64 67 69 statistically significant decreases were reported for 78.6% (BMI in kg/m 2 ), 44.4% (fat mass) and 69.2% (per cent fat) of results. While this may lead one to question the benefits of exercise for improving adiposity in overweight and obese children and adolescents, this would be shortsighted since it relies on the vote-counting approach,70 an approach that has been shown to be less valid than the meta-analytic approach 70.…”

“…However, previous randomised trials limited to overweight and obese male and female children and adolescents have reached conflicting results with respect to exercise-induced changes in adiposity 13–69. For body mass index (BMI in kg/m 2 ), fat mass and per cent body fat, statistically significant decreases were reported for 45.2%, 50.0% and 40.0% of findings, respectively, as a result of exercise (aerobic, strength training or both) 13–69. When limited to studies that included aerobic exercise as an intervention,13 15–17 19 21 22 24 25 29 30 32–34 36 38–46 48 50–53 55 57–64 66 67 69 statistically significant decreases in BMI in kg/m 2 , fat mass, and per cent body fat were reported for 43.2%, 66.7% and 75.0% of findings.…”
