Generation 100: How Exercise Affects Mortality and Morbidity in the Elderly: A Randomized Control Study

Not Applicable

Active, not recruiting

• Conditions: Ageing
• Interventions: Other: Exercise intervention

• Registration Number: NCT01666340
• Lead Sponsor: Norwegian University of Science and Technology

Brief Summary

Hypothesis: Exercise will reduce morbidity and mortality rates in an elderly population. The extent of reduction will be intensity dependent.

Detailed Description

Literature lacks large controlled randomized studies that look at the effect of exercise training on morbidity and mortality. Generation 100 will be the first randomized, controlled clinical study where the primary objective is to study the effects of exercise training on morbidity and mortality in the elderly. Furthermore, the researchers will investigate whether there is a relationship between the exercise intensity and health benefits, with particular focus on major health problems in the elderly population. In addition to being a study, this is also an initiative to improve public health in all healthy individuals between 70-75 years of age in the Trondheim municipality. The participants will either be randomized to supervised exercise or follow current guidelines for physical activity on their own. Clinical examinations, as well as questionnaires, will be administered to all participants at baseline, after one year, after three years, and after five years. Additionally, participants will be followed-up by linking to relevant registers for up to 20 years.

Also data will be collected with the purposes of (a) investigating genetic predisposition for fitness and cardiovascular diseases, and (b) identification of potential targets for therapies.

The study seeks to determine if exercise training gives the seniors a longer active and healthy life.

Arm && Interventions

Group	Intervention	Description
Moderate intensity training	Exercise intervention	Exercise intervention: Moderate intensity Group of people asked to perform moderate training where they exercise at a given intensity (moderate as per Borg scale) for a certain amount of time
high intensity aerobic training	Exercise intervention	Exercise intervention: High intensity group performing high intensity training where they are required to raise their heart rate several times during the workout and reach perceived exhaustion of 16 on a Borg scale

Primary Outcome Measures

Name	Time	Method
Mortality	5 years follow up	using data from governmental registers

Secondary Outcome Measures

Name	Time	Method
General measurements	1 year follow up, 3 years follow up, 5 years follow up	resting blood pressure, resting fasting blood sample, resting heart rate, weight, height and waistline, body composition (muscle vs fat) questionnaires (activity, safety, monthly training diary) walking test, grip strength test, leg strength test, pulmonary function, physical activity level
Epigenetics	1 year follow up, 3 years follow up, 5 years follow up	transcriptomics (messenger RNAs and microRNAs) and proteomics arrays, aimed at blood-borne factors induced by training.
Morbidity	3 and 5 years	Look at morbidity after 3 and 5 years follow up(i.e. cardiovascular disease, cancer, etc.) using medical records and link to the different health registers.
