  Purpose

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.


Condition Intervention
Healthy Subjects Behavioral: 1 x 4 minute interval Behavioral: 4 x 4 minutes Intervals Behavioral: Moderate continuous Training

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Prevention
Official Title: Effect of Aerobic Interval Training on NEAT in Sedentary Men

Further study details as provided by Norwegian University of Science and Technology:

Primary Outcome Measures:
  • nonexercise activity thermogenesis [ Time Frame: 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:
  • Cardiopulmonary maximal oxygen uptake [ Time Frame: 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
