Effects of resistance versus endurance training on serum adiponectin and insulin resistance index

Abstract

Purpose: The purpose of the present study was to investigate the effects of resistance and endurance training on serum adiponectin and insulin resistance index (S I ) in healthy men. Methods: Twenty-four healthy males (age, 35-48 years) participated in the study. The subjects were randomly assigned to one of three groups: endurance training group (nZ8), resistance training group (nZ8) and control group (nZ8). Blood samples were taken in fasting state from all subjects. The experimental groups performed either endurance or resistance training 3 days a week for 12 weeks. The endurance training programme included continuous running at an intensity corresponding to 75-85% of maximal heart rate, while resistance training consisted of four sets of circuit weight training for 11 stations and at an intensity corresponding to 50-60% of one-repetition maximum. The maximum numbers of repetitions in each station was 12.Results: There were significant negative correlations between serum adiponectin and body fat percentage, waist-to-hip ratio, body mass index and the insulin resistance index at baseline, whereas changes in response to training were not significantly correlated. Both endurance and resistance training resulted in a significant decrease in the S I in comparison with the control group. However, serum adiponectin did not change significantly in response to resistance and endurance training. Conclusion: Endurance and resistance training caused an improvement in insulin resistance in healthy men, but this improvement was not accompanied by increased adiponectin levels.European Journal of Endocrinology 157 625-631

Review on Exercise Intervention Methods for Weight Loss in Obese Individuals

“…Obese individuals with higher fitness levels generally have lower mortality rates compared to sedentary normalweight counterparts [33]. Previous studies have shown increases in VO 2max from baseline levels after resistance exercise training [34] and combined aerobic and resistance exercise training [7,8,33]. In our study, a moderateintensity of 60% of estimated HRR was used for aerobic exercise to target greater fat oxidation rather than cardiorespiratory fitness improvements per se [35].…”

Effects of Ten Weeks of Aerobic Interval Training and Four Weeks Detraining on Plasma Adiponectin Level in Male Student Non-Athletes

“…Perhaps the subjects in the current study are the reason for the difference in the results of the present study. Ahmadizad et al examined the effect of aerobic exercise against resistance on adiponectin and concluded that there is a negative significant relationship between adiponectin levels and percentage of body fat compared to WHR and BMI [36]. Coker et al investigated the effect of exercise intensity (50% vs. 70% peak oxygen consumption) abdominal fat and adiponectin levels in the elderly.…”

Rôle de l’activité physique dans la lutte contre le syndrome métabolique infantile

“…Il semble aussi que les exercices de résistance de faible intensité provoquent une augmentation du contenu en GLUT-4, des récepteurs insuliniques, de la glycogène synthétase et de la protéine kinase B sans augmentation de la masse musculaire [48]. Enfin, deux études ont montré qu'une combinaison d'exercices aérobies et de résistance pouvait améliorer la sensibilité à l'insuline chez l'enfant sans variation de la composition corporelle [21] ou du taux sérique d'adiponectine [47].…”
