Effect of Exercise With Low Intensity and Longer Duration Versus 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.

Treatment and study plan

endurance exercise of different duration and intensity

Other

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.

Primary outcomes

  1. changes in maximal oxygen uptake

    Time frame: Maximal oxygen uptake will be measured at day 1 before training, then we will measure changes in maximal oxygen uptake after 8 weeks, and finally a follow up measurement of changes in maximal oxygen uptake after 1 year

Secondary outcomes

  1. endurance performance

    Time frame: one year

    work economy, lactate threshold will be measured toghether with maximal oxygen uptake to determine endurance performance.

  2. health effects

    Time frame: one year

    coronary flow reserve, blood pressure, maximal oxygen uptake
