Outcomes

Primary Outcome Measures

Maximal fat oxidation (MFO)
Maximal fat oxidation test (MFO) to determine the maximal fat oxidation during exercise (MFO), a gradual test on cycloergometer (Lode Excalibur, Netherlands) will be performed. The test will begin with a load of 15 Watts, increasing 15Watts every 3 minutes until the respiratory quotient reaches a stable value of 1 or higher. Throughout the test a cadence of 80 r.p.m. will be maintained. Calculation in the base of expired gases will be made for the estimation of grams per minute of fat oxidation.
Cardiorespiratory fitness
The maximal oxygen consumption (VO2max) during exercise in liters per minute by a gradual test on a cycle ergometer (Lode Excalibur, Netherlands) will be performed. The gas exchange will be measured by Jaeger MasterScreen CPX® (CareFusion, San Diego, USA)The test will be continuing the MFO from the load when the respiratory quotient reaches a stable value of 1 or higher. Once this point is reached, 15 Watts increments will occur every minute until exhaustion is reached, until achieving the VO2max. Throughout the test a cadence of 80 r.p.m. will be maintained. Heart rate will be recorded in beats per minute.
Blood samples
Glucose and insulin concentrations will be determined using ELISA technique and will be combined to report the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) insulin sensitivity index will be calculated
Appetite assessment
Since appetite feeling modulate nutritional behaviour, the evaluation of appetite among the intervention groups can improve the quality of the study from a comprehensive perspective. After a period of 8-10 hours of fasting, an analog visual scale (AVS) will be completed in order to ensure the appetite felt by the participant in the morning. The AVS runs from 1 to 10, being the lowest value no appetite at all, and the maximum full appetite.
Body composition: Fatmass and Fat-free mass.
Body composition will be estimated using a multifrequency bioimpedance of 8 electrodes previously validated (TANITAMC780MA). The calculation of impedance can estimate the fat mass and fat-free mass in kilograms. The patients will wear light clothing and will assume a posture in accordance with the manufacturers' instructions. Other previous considerations will be followed 24 hours before the measure: (i) to refrain from vigorous exercise, (ii) to take alcoholic drinks, (iii) to take energy drinks, and (iv) to be in a fasting state for at least 8 hours. Hydration status will be controlled through a urine color scale from clear to dark during the 7 days before assessment for adjusting variables.

Secondary Outcome Measures

Accelerometry
Physical activity assessment will be carried out through accelerometers (direct method) at the wrist during 7consecutive days. The data generated by the accelerometers will be analysed by using ActiLife 6.6.2 software (ActiGraph, Florida; USA), using Freedson (1998) cut-points for adults and Choi's validation. The software calculates in the base the movements of the accelerometer's time of light, moderate, and vigorous physical activity in minutes.
Assessed changes from physical activity
Physical activity assessment will be estimated by the participant's self-reported International Physical Activity Questionnaire Short Version (IPAQ-SF) previously validated in Spain. The IPAQ-SF estimates the sedentary time, moderate and vigorous activity time in minutes per week. The questionnaire made a classification in high physical activity level (>3000 of the metabolic equivalent of task (MET) minute per week in moderate or >1500 MET min/week in vigorous activity), moderate physical activity level (>600 MET min/week of moderate or vigorous activity), and low activity level (<600 MET min/week of moderate or vigorous activity)
Blood pressure
Systolic and diastolic blood pressures will be recorded three times by using the validated bloodpressure monitoring device with the participant seated, back supported in chair and feet flat on floor without legscrossed, after they rested 5 minutes. The guidelines of the Hypertension and Cardiology European Societies and the Spanish one will be used to classify blood pressure stages of participants.
Self-reported quality of life
Self-reported quality of life will be registered by applying the Short Form 36-health survey (SF-36) questionnaire previously validated in Spain. The SF-36 is a generic measure of quality of life and has been evaluated for a wide variety of medical conditions, including diabetes. The SF-36 includes 36 questions that evaluate 8 subscales, scores for each scale range from 0 to 100, with higher scores indicating a higher level of function or wellbeing. The physical component summary is derived from the 4 subscales of physical functioning, role physical, bodily pain, and general health; while the mental component summary is derived from the subscales of vitality, social functioning, role emotional, and mental health.

5. Study Description

Brief Summary
The project investigates the effects of two exercise protocols at different intensities, high-intensity interval training and constant load at Fatmax, for 12 weeks in maximal fat oxidation, hormonal regulation of appetite, and insulin sensitivity in persons with obesity and type 2 diabetes mellitus. The participants will be of both sexes with ages between 40 and 55 years, belonging to the Province of Cádiz. Sixty volunteers will be randomly allocated into three groups: High-Intensity Interval TRaining (HIIT), Fatmax, and control groups. The assessments will be at the previous exercise intervention, posterior the exercise intervention, and 12 weeks after the last intervention. The outcome variables will include body composition, oral glucose tolerance test, appetite, plasma glucose, lipids in plasma, hormones, and adipokines.
