Obesity is strongly associated with the degree of inflammation characterised by proinflammatory cytokines, such as tumour necrosis factor-α (TNF-α). Lifestyle modification with exercise is the right strategy because it can stimulate interleukin 6 (IL-6) secretion which acts as an anti-inflammatory. This study aimed to analyse the response of interval and continuous exercise to inflammatory markers in obese women. Twenty-four women participated in this study and were randomly divided into 3 groups: CONG (n=8, control group without any intervention): MCEG (n=8, continuous exercise group) and MIEG (n=8, interval exercise group). ELISA was used to measure the levels of IL-6 and TNF-α, pre-exercise and post-exercise. The data were analysed using the paired sample t-test. The mean levels of TNF-α, pre-exercise and post-exercise, were 19.35±2.73 vs 19.36±2.23 pg/ml (P=0.989) in CONG, 19.42±2.79 vs 16.63±0.82 pg/ml (P=0.017) in MCEG, and 19.46±3.08 vs 16.96±2.11 pg/ml (P=0.079) in MIEG. Mean levels of IL-6, pre-exercise and post-exercise, were 7.56±2.88 vs 7.66±4.12 pg/ml (P=0.957) for CONG, 7.68±3.41 vs 13.97±2.38 pg/ml (P=0.001) for MCEG, and 7.78±1.99 vs 13.66±3.55 pg/ml (P=0.001) for MIEG. We concluded that interval and continuous exercise decreased pro-inflammatory and increased anti-inflammatory cytokines.

The study purpose was to analyze the effect of continuous exercise and modification interval exercise on decreasing malondialdehyde (MDA) and blood lactate levels in non-professional Shorinji Kempo athletes. Materials and methods. This study used a quasi-experimental method with a randomized pretest posttest-only group design. Subjects were 16 male adolescents aged 18-20, body mass index (BMI) 20-24 kg/m2, who had normal blood pressure, normal resting heart rate, and no history of chronic disease. The subjects were randomly divided into two groups: CEG (n = 8, continuous exercise group) and MIEG (n = 8, modification interval exercise group). Continuous and modification interval exercises were carried out in 30 minutes/exercise sessions, with an intensity of 75% HRmax and 75% RM, as often as 3 times/week, for one week. Measurements of resting heart rate, blood lactate and MDA levels were performed 30 minutes pre-exercise and 10 minutes post-exercise. The data analysis technique used the Paired Sample T-Test and the independent T-test with SPSS software version 21. Results. The results showed significant differences in resting heart rate, blood lactate and MDA levels pre-exercise vs. post-exercise on CEG and MIEG (p ≤ 0.05). A difference was also observed in Delta (Δ) heart rate pre-exercise vs. post-exercise on CEG (–3.88 ± 3.36 bpm) and MIEG (–15.25 ± 3.45 bpm) (p ≤ 0.001), but no differences were observed in the Delta (Δ) blood lactate and MDA levels in both groups. Conclusion. Based on the study results, it was shown that continuous exercise and modification interval exercise increase blood lactate and MDA levels shortly after intervention but both exercises could reduce acute stress, which was indicated by a decrease in resting heart rate.

The study design was the randomized posttest-only group design, 24 tails, male Rattus Norvegicus Strain Wistar, 8 weeks, 160±20 grams and randomly divided into 4 groups. K1 (n=6, moderate intensity exercise, treadmill with a speed of 14-16 m/min for 15-30 minutes), K2 (n=6, moderate intensity exercise + giving Raja Banana peel extract, treadmill with a speed of 14-16 m/min for 15-30 minutes), K3 (n=6, high intensity exercise, treadmill at a speed of 22-25 m/min for 10-20 minutes) and K4 (n=6, high intensity exercise + giving Raja Banana peel extract, treadmill with a speed of 22-25 m/min for 10-20 minutes). The training interventions were conducted at 17.00-21.00 p.m with a frequency of 7 times/week for 8 weeks. The blood was drawn 12 hours after the last exercise intervention. it is concluded that giving Raja Banana peel extract after moderate and high intensity exercise reduced MDA levels in rats.
