History of Changes
  Purpose

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.

Primary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • endurance performance [ Time Frame: one year ] [ Designated as safety issue: No ]
    work economy, lactate threshold will be measured toghether with maximal oxygen uptake to determine endurance performance.

  • health effects [ Time Frame: one year ] [ Designated as safety issue: No ]
    coronary flow reserve, lipid profile, blood pressure, maximal oxygen uptake

Arms Assigned Interventions
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.
 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: long duration at moderate training
a continuous training group exercising at 70% of maximal heart rate for 90 minutes.
 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.
