The Effect of Personal Activity Intelligence Versus 10,000 Steps Daily on Cardiorespiratory Fitness

Not Applicable

Completed

• Conditions: Physical Activity; Obesity
• Interventions: Behavioral: personal activity intelligence; Behavioral: 10,000 steps daily

• Registration Number: NCT03336047
• Lead Sponsor: Norwegian University of Science and Technology

Brief Summary

A high physical fitness can prevent cardiovascular disease. Which form of exercise training is efficient at improving fitness is well known. The challenge is to get people to do it. Personal activity intelligence (PAI) is an algorithm developed for this challenge. It gives a score that tells the users whether they are active enough to achieve the maximum health benefit of exercise based on their heart rate. It has been shown that people who obtain 100 PAI a week have less cardiovascular disease, but intervention studies showing that PAI can improve physical fitness are so far lacking.

Step counters have received a lot of attention and 10 000 steps a day is a common recommendation, but little is known about the physiological adaptations to this intervention.

This study will compare the effect of physical activity with a value of 100 PAI points a week with 10 000 steps a day in healthy, but overweight (body mass index \> 25) participants between 30 and 50 years of age.

Arm && Interventions

Group	Intervention	Description
using personal activity intelligence	personal activity intelligence	Subjects will be encouraged to obtain 100 PAI points per week, monitored by Mio Slice and the Mio Pai 2.0 smart phone application
10,000 steps daily	10,000 steps daily	Subjects will be encouraged to obtain 10 000 steps a day, monitored by a step counter (fit bit zip)

Primary Outcome Measures

Name	Time	Method
Maximal oxygen uptake	After the intervention period (8 weeks)	The highest amount of oxygen the body can take up, achieved at maximal exercise at the end of an incremental treadmill test measured through ergospirometry. The difference between the two groups post-intervention will be used, while controlling for a pre-intervention value.

Secondary Outcome Measures

Name	Time	Method
Body composition	After intervention period (8 weeks)	Body mass, fat mass and lean mass will be measured using a bio impedance analysis which weighs the participants and uses bio impedance to also assess fat mass and lean mass.; The difference between the two groups post-intervention will be used, while controlling for a pre-intervention value.
