Interval Training and Resting Metabolism

Not Applicable

Completed

• Conditions: Healthy Subjects
• Interventions: Behavioral: 4 x 4 minutes Intervals; Behavioral: 1 x 4 minute interval; Behavioral: Moderate continuous Training

• Registration Number: NCT01313468
• Lead Sponsor: Norwegian University of Science and Technology

Brief Summary

It has been reported that obese individuals are seated 2 ½ hour more than lean individuals and that non exercise thermo genesis (NEAT) may vary with as much as 2000 Kcal/day between equal size people due to different occupational and leisure time activities. The primary aim of the study is to investigate if 10 weeks of exercise training increase NEAT in sedentary men.

Subject will be randomized to three different training intervention, with 3 exercise session each week for 10 weeks. NEAT will be measured using an activity sensor and recorded over a 7 day period both before and after training.

Arm && Interventions

Group	Intervention	Description
4 x 4 Interval	4 x 4 minutes Intervals	4 x 4 minutes of high intensity intervals at 90-95% of maximal heart rate separated by 3 minutes of active brakes in between at 70% of maximal heart rate.
1 4 minutes interval	1 x 4 minute interval	1 x 4 minutes intervals at 90-95% of HR max
Moderate continuous Training	Moderate continuous Training	47 minutes of Moderate continuous Training

Primary Outcome Measures

Name	Time	Method
nonexercise activity thermogenesis	Baseline and 10 weeks	NEAT Will be measured using an activity sensor. Physical activity is recorded over a 7 day period. The energy equivalent of each of these activities is determined. The time spent in each activity is then multiplied by equivalent for the activity. The values are then summed to derive an estimate of NEAT.

Secondary Outcome Measures

Name	Time	Method
Cardiopulmonary maximal oxygen uptake	Baseline and 10 weeks	The secondary aims are to investigate the changes in maximal oxygen uptake, heart function, and body composition in response to interval training
