Abstract
The aim of this study was to investigate the effects of eight weeks Circuit Resistance Training (CRT) on some inflammatory cytokines, blood pressure and insulin resistance in pre-hypertensive obese women. For this purpose, 24 pre-hypertensive obese women (mean age: 44.73±4.43 years, body mass index: 32.39±3.8 kg/m2, systolic: 13.21±0.61 mmHg and diastolic: 8.65±0.33 mmHg blood pressure levels), were conveniently selected and randomly divided into CRT training (n=12) and Control (n=12) groups. The intervention consisted of 8 weeks of circuit resistance training, with a frequency of 3 sessions per week, and each session lasted 50 to 60 minutes (15 minutes of warm-up, 30 minutes of weight training, and 10 minutes of cooling). Resistance trainings were performed with an intensity of 40% 1RM for upper body and 60% 1RM for lower body movements. Measurements and blood sampling were done pre and post 8 weeks of training. Data were analyzed using Shapiro-Wilks and analysis of variance with a 2×2 design at a significance level of p˂0.05. The results showed that 8 weeks of CRT have significant effects on body fat percent (p=0.007), Waist to Hip Ratio (p=0.017), systolic (p<0.0005) and diastolic (p=0.016) blood pressure and insulin resistance (p=0.043). However, it was not significant in the inflammatory cytokines IL-1β and TNF-α (P ≤ 0.05). The reason could be the type of exercise selected. Depending on the intensity, frequency and duration of the training, they can affect the levels of inflammatory cytokines to a different extent.
