Clinical Trial 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.

Intervention

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	No
Secondary	endurance performance	work economy, lactate threshold will be measured toghether with maximal oxygen uptake to determine endurance performance.	one year	No
Secondary	health effects	coronary flow reserve, blood pressure, maximal oxygen uptake	one year	No
