Criterion validity and reliability of a smartphone delivered sub-maximal fitness test for people with type 2 diabetes.

ABSTRACT:

Background

Prevention of multi-morbidities following non-communicable diseases requires a systematic registration of adverse modifiable risk factors, including low physical fitness. The aim of the study was to establish criterion validity and reliability of a smartphone app (InterWalk) delivered fitness test in patients with type 2 diabetes.

Methods

Patients with type 2 diabetes (N = 27, mean (SD) age 64.2 (5.9) years, BMI 30.0 (5.1) kg/m², (30 % male)) completed a 7-min progressive walking protocol twice (with and without encouragement). VO₂ during the test was assessed using indirect calorimetry and the acceleration (vector magnitude) from the smartphone was obtained. The vector magnitude was used to predict VO_2peak along with the co
