The response of selected adipokines and insulin resistance to interval resistance trainingwith different intensities in men with obesity

Introduction: this study aimed to evaluate the effect of 12 weeks ofinterval resistance training with different intensities (low, mediumand high) on bone morphogenetic protein 2 (bmp-2), bonemorphogenetic protein 4 (bmp-4) and insulin resistance in obesemen.materials and methods: forty-four obese not trained men, afterdetermining 1rm and based on anthropometric characteristics weredivided into the control, low-intensity interval resistance training,medium-intensity interval resistance training, high-intensity intervalresistance training groups (in each group, n=11). the protocol ofinterval resistance training includes 8 movements which wereperiodic and in different intensities in the form of 3 set 10 repetitionswith 80% 1 rm, rest between sets active, and with 20% intensity andthe number of repetitions 15 in the high-intensity group, in themedium intensity group in the form of 3 sets 13 repetitions with 60%rm, resting active sets with 20% intensity and number 15 repetitionsand in the low-intensity group in the form of 3 sets of 20 repetitionswith 40% 1 rm, rest between sets was active with 20% intensity andthe number of repetitions was 15. the first fasting blood sample wasobtained 48 hours before and the second blood sample was collected48 hours after a twelve-week training period. then the measurementswere performed.results: the 12 weeks of interval resistance training with differentintensities in the training groups led to a significant decrease in bmp-2 and insulin resistance compared to the control group (p < 0.001)but for bmp-4 these decreases were not significant (p = 0.055).conclusion: the study showed that different intensities of resistanceinterval training, especially moderate and high intensity training, candecrease the bmp-2, bmp-4 levels and improve insulin resistance.
