NCT01443507

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • changes in maximal oxygen uptake

    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 (2)

  • endurance performance

    one year

  • health effects

    one year

Study Arms (2)

high intensity long interval

EXPERIMENTAL

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.

Other: endurance exercise of different duration and intensity

long duration at moderate training

EXPERIMENTAL

a continuous training group exercising at 70% of maximal heart rate for 90 minutes.

Other: endurance exercise of different duration and intensity

Interventions

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.
