Comparison of the effect of aerobic,resistance and combined training on someinflammatory markers in obese men

Abstract

Objectives. — This study aimed to examine the impact of 12 weeks of aerobic interval, resistanceand combined exercise on inflammatory markers of TNF-a, IFN-y, Metrnl and IL-4 in obese men.Methods. — Forty-four individuals (35—55 years; body mass index (BMI): 30—40 kg/m2) voluntar-ily participated, and were randomly divided into four groups: aerobic interval exercise (n = 10)(5 × 3-min intervals at ∼40—80% peak heart rate), resistance exercise (n = 11) (2—3 sets, 8—20repetitions at 40—80% one-repetition maximum), combined exercise (n = 12) (a combination ofboth aerobic and resistance exercises) and control (n = 11). The exercise protocol in all threegroups was 12 weeks with a frequency of three sessions per week.Results. — IL-4 increased significantly in aerobic interval (P = 0.005), resistance (P = 0.005),and combined (P = 0.022) exercise groups. TNF- decreased significantly only in the aerobic(P = 0.005) and combined (P = 0.012) groups, but it increased in the resistance group (P = 0.025).None of the exercise interventions resulted in a significant change in Meteorin-like protein(Metrnl) and IFN- levels (P > 0.05).
