Effect of Short-term High-intensity Interval and Fatmax Training on Aerobic and Metabolic Fitness in Obese Subjects
In Brief
A clinical study evaluating Fatmax group and HIIT group for Obesity. Completed, enrolled 19 participants across 1 site.
Detailed Summary
Obesity is commonly associated with insulin resistance and hyperinsulinemia, which seem to be linked with an impaired ability to oxidize lipids, particularly in class III obese individuals \[Body Mass Index (BMI): \> 40 kg\*m-2\]. Exercise training is an effective strategy to improve insulin sensitivity and to reduce the risk of type 2 diabetes. This study aimed to compare the effects of two different 2-wk-long training modalities \[continuous at the intensity eliciting the maximal fat oxidation (Fatmax) versus adapted high intensity interval training (HIIT)\] on aerobic and metabolic fitness of class II and III obese men. It was hypothesized that, because of the nature of HIIT in the stimulation of rapid changes, aerobic fitness, fat oxidation rates during exercise and insulin sensitivity would be improved to a greater extent when adapted HIIT compared to Fatmax training.

Timeline
Interventions
For the Fatmax group each session will consist of 40-50 min of continuous exercise with an intensity that corresponded to the individual Fatmax (moderate intensity)
For HIIT group, each session will consist of 10x60-s cycling intervals interspersed with 60-s of recovery. The workloads will be selected to elicit a heart rate of \~90% maximal heart rate during the intervals with a pedal rate of 90-100 revolutions.min-1, whereas during recovery, the participants will be allowed to pedal against a resistance of 50 W
