Effect of Exercise With Low Intensity and Longer Duration Versus High Intensity Interval Training

Phase 2

Completed

• Conditions: Healthy Subjects
• Interventions: Other: endurance exercise of different duration and intensity

• Registration Number: NCT01443507
• Lead Sponsor: Volda University College

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.

Arm && Interventions

Group	Intervention	Description
high intensity long interval	endurance exercise of different duration and intensity	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.
long duration at moderate training	endurance exercise of different duration and intensity	a continuous training group exercising at 70% of maximal heart rate for 90 minutes.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
endurance performance	one year	work economy, lactate threshold will be measured toghether with maximal oxygen uptake to determine endurance performance.
health effects	one year	coronary flow reserve, blood pressure, maximal oxygen uptake
