Brief Summary:
Exercise is a key component of obesity management. Obese subjects cannot attend or sustain exercise program because of increased general fatigue, dyspnea and muscle fatigue. And they feel more exertion when comparing with normal weight subjects. Reduced-exertion high-intensity interval training (REHIT) is a alternative method to continuous exercise programs. The investigators aimed comparing metabolic effects of REHIT and continuous exercise in young adults, in this study.

Arm Intervention/treatment
Active Comparator: Continuous Exercise
At %60 of maximal heart rate, 30-60 minutes exercise
Other: Continuous Aerobic Exercise
At %50 of maximum heart rate, 30-60 minutes aerobic exercise

Experimental: REHIT Exercise
At %100 of heart rate 15 seconds, after this period 15 sec recovery period for all step
Other: REHIT Exercise

-Start with warm-up period --> %50 of maximum work rate, 3 minutes

One Exercise Cycle consists of:

  • 15 seconds exercise period: %100 of maximum work rate
  • 15 seconds recovery period: %50 of maximum work rate

Total Duration: 10 minutes

Primary Outcome Measures :
  1. Aerobic Capacity [ Time Frame: 1 year ]
    Maximum Oxygen Uptake

Secondary Outcome Measures :
  1. Total Exercise Duration [ Time Frame: 1 year ]
    Exercise Test Duration

Other Outcome Measures:
  1. Body Fat Percentage [ Time Frame: 1 year ]
    Total Body Fat Percentage
