Brief Summary

The Elite HRV is a reliable HRV analysis tool and could be a valid option to replace the Polar V800. The objective of study is Comparing the HRV index recorded with the mobile app Elite HRV and with the multisport watch Polar V800. Individuals will submit to two RR interval recordings with a Polar H7 strap that sent the data either to the Polar V800 heart rate monitor or to the Elite HRV app. The volunteers will supine position and breathing spontaneously, and the RR intervals will collect during 25 minutes. Subsequently, without warning the subject, the strap will connect to a nother device, and the second 25minute evaluation was made. The order in which the devices will use is randomized and the HRV indexes will generated via Kubios HRV.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

To determine the sample size, a sample size calculation was performed, assuming the following parameters: alpha of 5%, beta of 20% (power = 80%) and difference between groups of 10% regarding the scores on the scale. With these data, 30 subjects were calculated in each study arm.

You may qualify if:

  • Individuals over 18 years of age
  • Apparently healthy

You may not qualify if:

  • Diagnoses of previously installed heart disease
  • Continuous medication use that can alter HRV
  • Use of any substance that could influence the autonomic nervous system, such as caffeinated drinks and foods.
