Effect of Exercise With Low Intensity and Longer Duration Versus High Intensity Interval Training
Does Endurance Exercise With Low Intensity and Longer Duration Improve Aerobic Capacity to the Same Extent as High Intensity Interval Training?
The purpose of the study is to compare exercise at 70% of maximal heart rate were total energy expenditure is twice compared to interval training at 90- 95% of maximal heart rate. Since 70% of maximal heart rate is well above the minimum threshold for improvements in maximal oxygen uptake it should be suited to investigate the effect of duration.

Phase 2
Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Factorial Assignment
Masking: Open Label
Primary Purpose: Prevention
Healthy Subjects
Other: endurance exercise of different duration and intensity
Two interventions are compared with aerobic capacity as the main outcome. one group exercise at 70% of maximal heart rate for 90 minutes 3 times per week. group two exercise performe10 minutes warm up at 70% of maximal heart rate 4 x 4 minutes intervals at 90-95% of maximal heart rate with 3 minutes active pause at 70% of maximal heart rate in between, and finally 5 minutes cooling down at 70 % of maximal heart rate.
  • Experimental: high intensity long interval
    A group training four by four minutes interval at 90-95% of maximal heart rate dispersed by three minutes active pauses at 70% of maximal heart rate.
    Intervention: Other: endurance exercise of different duration and intensity
  • Experimental: long duration at moderate training
    a continuous training group exercising at 70% of maximal heart rate for 90 minutes.
    Intervention: Other: endurance exercise of different duration and intensity
