“…The results of previous studies have shown, that acute episodes of mild or moderate exercise in healthy, lean subjects did not affect the adiponectin levels (20,26,27). Some researchers have reported that exercise increased adiponectin levels (28,29,30). However, in another study performed by Kraemer et al, plasma adiponectin levels of young athletes were demonstrated to be decreased after acute strenuous rowing (31).Our fi ndings are similar to this study.…”

BACKGROUND: Adiponectin levels with long-term swimming exercise have been never investigated in spontaneously hypertensive rats (SHR). OBJECTIVE: This study was aimed to investigate the effects of exercise and detraining process on the adiponectin plasma levels of spontaneously hypertensive rats (SHR) and healthy Wistar-Kyoto rats (WKY). MATERIAL AND METHODS: The rats in the exercise groups were swimming for 10 weeks, 5 days/week, one hour in a day. The detraining rats were left to be sedentary in their cages for 5 weeks after 10 weeks of exercise period. RESULTS: The plasma adiponectin levels decreased in E and SHRE groups compared to the SC and the SHR groups, respectively. In addition, blood pressure was decreased in the exercise groups vs their controls. The adiponectin level was not found to be signifi cantly different in ED and SHRED groups compared to their controls. The blood pressure did not differ between SDC and ED groups, although in the SHRED group it was found to be lower than in SHRSD group rats. CONCLUSION: The results of this study showed that exercise reduced plasma levels of adiponectin in healthy and spontaneously hypertensive rats. However, this difference disappeared at the end of the training processes. Our results suggest, that changes in plasma adiponectin levels are not responsible for changes in blood pressure (Tab. 2, Fig. 2, Ref. 43). Text in PDF www.elis.sk.

“…It is known that interleukin-6 (IL-6) promotes the expression of leptin mRNA and inhibits adiponectin mRNA expression, and physical activity may be impacting serum leptin and adiponectin levels by decreasing IL-6 [49,50]. Furthermore, catecholamines's response to exercise may also be an important factor in the exercise-induced changes in serum leptin and adiponectin levels [33,48].…”

“…Of the 513 potentially relevant publications identified in the initial search and reference lists, 28 RCTs satisfied the inclusion criteria and were included in the meta-analysis. Of these 28 RCTs, 9 contained multiple exercise protocols with intervention groups of different modalities or intensities of exercise with only one control group for comparison [31][32][33][34][35][36][37][38][39]. As a result, we split the shared control group into 2 or more groups as described above [30], which resulted in 21 studies.…”

“…Since almost all of the RCTs included in the present study were performed under supervision and reported good compliance, we determined that there was no need to stratify them into subgroups by presence or lack of supervision. Eight studies from 6 publications measured serum leptin levels [18,20,21,27,34,37] and 15 from 8 publications measured serum adiponectin levels [18,20,27,33,[37][38][39][40] did not describe the exact exercise duration per week. In other words, the data of these studies were insufficient for inclusion in a subgroup analysis of exercise duration ( ≥ 150 min/wk vs. < 150 min/wk).…”

Previous reports have shown that exercise improves serum leptin and adiponectin abnormalities in overweight and obese individuals; however, results to date are controversial. Here we performed a systematic review and meta-analysis of the available randomized controlled trials (RCTs) of the possible beneficial action of exercise on serum leptin and adiponectin levels in overweight and obese individuals. We searched PubMed, EMbase, The Cochrane Library, and the Clinicaltrial.gov databases for relevant studies published between January 1980 and September 2015. Two independent reviewers extracted relevant data and assessed study quality and risk of bias. Data were pooled using a random-effects model for leptin and a fixed-effects model for adiponectin. Effect of size was expressed as mean difference (MD) with 95% confidence interval (CI). Heterogeneity was assessed (Cochran Q-statistic) and quantified (I ). Twenty-eight RCTs (40 studies) were identified, of which 24 were on the effects of exercise on leptin (n=1 358) and 31 referred to changes in adiponectin (n=1 774). Our analysis revealed that exercise significantly reduced serum leptin (MD=-2.24 ng/ml; 95% CI, -3.26, -1.23; p<0.001) and increased adiponectin (MD=0.44 μg/ml; 95% CI, 0.13, 0.75; p=0.005) levels compared to no exercise as well as control (who were also overweight or obese). Exercise, particularly aerobic exercise, had a significant effect on serum leptin and a possible influence on adiponectin levels, suggesting its therapeutic implications.

“…In contrast, Fatouros et al ( 13 ) indicated that high and moderateintensity resistance training can increase adiponectin levels. Even more recent studies have failed to show consistent findings ( 14 , 15 ). Asad et al ( 14 ) found that resistance training didn’t alter adiponectin resting levels in overweight untrained men.…”

Background:Circulating levels of adiponectin and testosterone decrease in obese men and this increases risks of cardiovascular disease and diabetes.Objectives:The purpose of this study was to survey changes of serum adiponectin and testosterone concentrations following twelve weeks resistance training in obese young men.Patients and Methods:In a semi-experimental study, twenty one obese young men were randomly placed in two groups: resistance training (26.5 ± 2.8 years) and control (27.4 ± 2.9 years). General characteristics of subjects and serum levels of adiponectin and testosterone were assessed before and after training. Resistance training protocol consisted of twelve weeks weight training (3 sessions per week, 10 exercises, 3 sets of 8 - 12 repetitions in each exercise, intensity 60% - 80% of one repetition maximum, rest between sets 1 minute and between exercises 2 minutes, duration of main training 20 - 40 minutes per each session).Results:Resistance training had no significant effect on body weight and body mass index (P > 0.05), whereas it decreased body fat percent (P = 0.017). Also, serum adiponectin (8.1 ± 1.8 vs. 10.5 ± 2.3 μg/mL) and testosterone concentrations (6.9 ± 2.4 vs. 8.2 ± 1.7 ng/mL) were increased after resistance training (P = 0.033, P = 0.018 respectively), while there were no significant changes in serum levels of these hormones in control group (P > 0.05).Conclusions:Twelve weeks of resistance training increased serum concentrations of adiponectin and testosterone in obese young men. With respect to inverse associations between changes of adiponectin and testosterone with BFP and insulin level variations after resistance training, it is recommended that obese young men do resistance training to benefit useful decreasing/preventive effects of this type of training against the risks of cardiovascular diseases and diabetes.
