Background: Obesity and being overweight elevate triglycerides, blood cholesterol, blood pressure, and LDL levels while decreasing HDL levels. This study aimed to examine the impact of eight weeks of interval training combined with melatonin consumption on novel obesity indicators and the atherogenic index in overweight and obese women.Methods: This semi-experimental, applied research involved 40 women aged between 30 to 45 years. They were randomly divided into four groups of ten each: intense interval training plus melatonin consumption (Group I), intense interval training plus placebo (Group II), melatonin consumption only (Group III), and a control group. The high-intensity interval training was conducted over eight weeks, with three sessions weekly. The regimen progressed from 5 repetitions in the first and second weeks to 6 in the third and fourth weeks, 7 in the fifth and sixth weeks, and 8 in the final two weeks. Groups I and III consumed 3 mg of melatonin tablets (manufactured by Razak company, Iran) nightly, an hour before bedtime, for the study duration. Data were analyzed using SPSS version 22 at 0.05 significance level.Results: The combination of eight weeks of interval training and melatonin consumption significantly impacted the visceral adiposity index (VAI), atherogenic plasma index (AIP), TC/HDL-c ratio, and HDL-c levels in overweight and obese women (P=0.001 for each). However, there were no significant effects on the ApoA-1/ApoB ratio, body adiposity index (BAI), or ApoA- 1 and Apo B levels (P=0.089, P=0.053, P=0.696, P=0.156, respectively).Conclusion: Intensive interval training coupled with melatonin supplementation positively influences obesity management, weight control, and cardiovascular disease risk reduction in overweight and obese women.

Background: Exercise is believed to be a non-pharmacological approach to treat hypertension. The present study was conducted to investigate the impact of high-intensity interval training (HIIT) and isometric handgrip (IHG) exercise on hemodynamic responses of High blood pressure women. Methods: In this experimental study 45 sedentary women (age, 45±5 years) from the Al-Zahra Heart Hospital, Shiraz-Iran (2019) with pre to stage 1 hypertension, without any chronic disease, who volunteered to participate in the research. The subjects were randomly divided into three groups of 15 members: Acute HIIT, Acute IHG exercise, and control. Blood pressure (systolic, diastolic, and mean), rate pressure product and heart rate were measured employing Aneroid Sphygmomanometer Polar HR recorder at the pre-workout time, 0 (immediately after exercise), 5, 10, 15, 30, 45, 60 minutes during the recovery period. The data were analyzed using repeated-measures ANOVA and Bonferroni post hoc test. Results: Our results revealed a significant difference among the study groups regarding blood pressure factors (systolic and mean), heart rate and rate pressure product (P=0.001). The significant decrease in blood pressure in HIIT (P=0.001) and IHG (P=0.001) groups during 60 and 30 minutes of recovery was equal to 10 and 7 mmHg, respectively, and no significant difference was observed in the control group at different times. In response to the HIIT protocol, the heart rate and rate pressure product were significantly higher than the IHG and control groups. Conclusion: Over the recovery period, there was a significant improvement in hemodynamic factors of hypertensive women independent of the type of exercise. However, HIIT training had a longer lasting decrease in blood pressure.
