Brief Summary:

High-intensity interval training (HIIT) is currently considered one of the most effective strategies to improved cardiorespiratory fitness, which is recognized as a protective factor for cardiovascular diseases and metabolic diseases such as overweight and obesity. However, current evidence is still limited and requires clarity (frequency, time per session and intensity) regarding to greater increases attributed to HIIT.

The aim of this study is to compare the effect of a low-volume high-intensity interval training versus a moderate-intensity continuous exercise on maximal oxygen consumption in overweight women 18 to 44 years old.


Condition or disease Intervention/treatment Phase
Healthy Volunteers Other: High-intensity interval training Other: Comparator: Moderate-intensity continuous exercise Not Applicable

Detailed Description:

Thirty-six women will be randomly assigned to one of two aerobic exercise on a real-life setting supervised for a physical activity instructor. The interventions will performed three times a week for ten-weeks (on alternate days).

The first two weeks will correspond to the conditioning period (30 minutes between 55-65% of maximum heart rate (HRmax). From week three, 18 participants will perform 30 minutes of continuous exercise at an intensity between 65-75 % of HRmax, and the remaining 18 will complete 21.5 minutes of interval exercise at an intensity between 90-95% of HRmax, with recoveries between 50-55% of HRmax.

All Participants will be evaluated to measure their maximal oxygen consumption, total body fat, waist circumference, body mass index, systolic blood pressure, diastolic blood pressure, prior to start the interventions and at the end of the program (week 11).

Arm Intervention/treatment
Experimental: High-intensity interval training Other: High-intensity interval training
21.5 minutes of high-intensity interval exercise at an intensity between 90-95 of HRmax (15x30 s), with recoveries at 50-60% of HRmax (14x60 s). 24 sessions, 3x weekly of walking and running outdoors on a sports field in a supervised manner.

Active Comparator: Moderate-intensity continuous exercise Other: Comparator: Moderate-intensity continuous exercise
30 minutes of continuous exercise at an intensity between 65-75% of HRmax. 24 sessions, 3x weekly of walking and jogging outdoors on a sports field in a supervised manner




Primary Outcome Measures :
  1. Change in maximal oxygen consumption [ Time Frame: Baseline and after 10 weeks ]
    Maximal oxygen consumption will be obtained using a graded exercise test on a treadmill (Trackmaster® model TMX 425C) using a portable K4b2 gas analyzer (Cosmed Inc., IL, USA)


Secondary Outcome Measures :
  1. Change in total body fat [ Time Frame: Baseline and after 10 weeks ]
    Total body fat will be obtained using an Omron® HBF-510 (Omron Healthcare, Inc. Bannockburn, IL, USA) bioelectrical impedance machine.
