简要总结
Several studies have shown relationship between exercise intensity and improvement cardiometabolic health such as body composition, endothelial function, blood pressure and blood lipids. It has been suggested that high intensity interval training and also strength or resistance training generate positive effects on metabolic risk factors, nevertheless the comparison between both types of training and their combination has not yet provided conclusive evidence. Also, it has been shown that dietary restriction has similar or more positive effects that exercise alone and the effect is greater when it is combined with exercise. For these reasons, it is necessary to clarify which type of training, in combination with a dietary restriction, is more effective to improve cardiometabolic health
详细描述
The investigators hypothesized that high intensity interval, resistance training or combined training would result in similar improvements in cardiometabolic health as compared to the usual clinical care in a cohort of sedentary overweight (age 30-50 years old).

研究组 & 干预措施
High Intensity Interval
Walking on a treadmill 4min at 80-90% peak heart rate and recovery 4 min at 65% peak heart rate until expenditure of 300 kcal during adaptation (first 4 weeks) and 500 kcal after week number 4 until the end of training.
干预措施: High Intensity Interval (Behavioral)
Resistance training
Completing a resistance circuit (including upper and lower muscle groups) as many times as needed according to subject weight until expenditure of 300 kcal during adaptation (first 4 weeks) at 20-30% of 1 one-rep max and 500 kcal after week number 4 until the end of training, at 40-60% of one-rep max.
干预措施: Resistance training (Behavioral)
Plus: High Intensity Interval + Resistance Training
Walking on a treadmill as intervention 1 until 50% the energy expenditure prescribed is reached, then completing a resistance circuit until 100% energy expenditure is reached. Exercise will be performed at three sessions per week.
干预措施: Plus: High Intensity Interval + Resistance Training (Behavioral)
Usual clinical care
This group will receive the usual clinical care according to the consensus recommendations of the national goals for cardiovascular health promotion and disease reduction of the American Heart Association and Colombian guidelines COLDEPORTES.
干预措施: Usual clinical care (Other)
