Physical activity has the potential to reduce cardiometabolic risk factors but evaluation of different intensities of physical activity and the mechanisms behind their health effects still need to be fully established. This study examined the effects of sedentary behaviour, light-intensity training, and high-intensity interval training on biometric indices, glucose and lipid metabolism, inflammatory and oxidative stress markers, and vascular and cardiac function in adult rats. Rats (12 weeks old) were randomly assigned to 1 of 4 groups: control (CTL; no exercise), sedentary (SED; no exercise and housed in small cages to reduce activity), light-intensity trained (LIT; four 30-min exercise bouts/day at 8 m/min separated by 2-h rest period, 5 days/week), and high-intensity interval trained (HIIT, four 2.5-min work bouts/day at 50 m/min separated by 3-min rest periods, 5 days/week). After 12 weeks of intervention, SED had greater visceral fat accumulation (p < 0.01) and slower cardiac conduction (p = 0.04) compared with the CTL group. LIT and HIIT demonstrated beneficial changes in body weight, visceral and epididymal fat weight, glucose regulation, low-density lipoprotein cholesterol, total cholesterol, and mesenteric vessel contractile response compared with the CTL group (p < 0.05). LIT had significant improvements in insulin sensitivity and cardiac conduction compared with the CTL and SED groups whilst HIIT had significant improvements in systolic blood pressure and endothelium-independent vasodilation to aorta and mesenteric artery compared with the CTL group (p < 0.05). LIT and HIIT induce health benefits by improving traditional cardiometabolic risk factors. LIT improves cardiac health while HIIT promotes improvements in vascular health.

The increased prevalence of obesity has compromised the health of Brazilian adolescents. Regular exercise and lifestyle changes are recommended as prevention and treatment. However, there is no consensus on the dose-response of exercise programs. This study aims to verify the effectiveness of a high-intensity interval training program in the aquatic environment (HIITAQ) on physical fitness and cardiometabolic risk factors in obese adolescents. The sample consisted of 18 adolescents of both sexes, aged 12 to 17 years, diagnosed with obesity. Anthropometric variables, physical fitness, blood glucose, and lipid profile were evaluated before and after 12 weeks of training. The program consisted of two sets of 4-8 repetitions lasting 30 seconds (85% -95% of maximum heart rate) for 60 seconds of the active rest interval. After the exercise program, there was a reduction in body mass index z-score, BMIz (p <0.01), reduction of Total Cholesterol, TC (p <0.01), and LDL (p <0.01). There was an increase in basal metabolic rate (p <0.01) and peak VO2 (p <0.01). No differences were observed after training in the percentage of fat, body mass index, BMI, waist/height ratio WHtR, fasting blood glucose, insulin, and HDL-c (p>0,05). The high-intensity training program in the aquatic environment was effective in reducing cardiometabolic risk factors.

Limited data is available on the sex differences and individual responses of cardiometabolic parameters adjusted with potential confounders (i.e. sex, age, baseline values) after a longer term Mediterranean diet (MedD) and high intensity interval training (HIIT) in obese subjects. The objective of this study was to compare the effects of nine-month MedD counseling and supervised HIIT on cardiometabolic risk factors and individual responses in obese women (n = 99) and obese men (n = 35). Body composition (body mass, fat mass, lean body mass, waist circumference), cardiorespiratory fitness (METs), and cardiometabolic risk factors (blood pressure, blood sample variables) were measured at baseline and after nine months of a program combining MedD and HIIT two to three times a week. When adjusted with sex, age, and baseline values, obese women similarly improved their body composition, METs, and cardiometabolic risk factors vs. obese men. The proportion of responders according to clinical cutoff levels were the same in obese women and men. A longer MedD and HIIT intervention similarly improves body composition, cardiometabolic risk factors, and individual responses in obese women and men, even after adjustment of confounders (sex, age, baseline value).
