October 19, 2022 updated by: Vilnius University
The Development and Application of a Toolset for Monitoring Personalized Physical Activity and Evaluation of Its Effectiveness in Individuals With Metabolic Syndrome
A prospective intervention study to evaluate the effectiveness of the developed toolset for remote physical activity monitoring to improve arterial stiffness and other cardiometabolic parameters and to increase physical activity levels and the compliance to the prescribed exercise in individuals with metabolic syndrome.

Conditions
Detailed Description
At first, all subjects of the prospective study participated in the 2-month outpatient aerobic exercise program, which consisted of 40 aerobic training sessions on a cycle ergometer 5 times/week for 40 min.
During all training sessions, heart rate was maintained at the targeted level, which was obtained individually by cardiopulmonary test.
After 2 months, during individual motivational consultations, all participants received recommendations for home-based training and were randomly allocated to the intervention or the control group.
Then only the intervention group subjects participated in the 6-month home-based aerobic exercise program using a wearable heart rate monitor, which was connected to the smartphone via Bluetooth.
The intervention group subjects used a smartphone application created for the study.
The control group participants were asked to exercise at home for 6 months without wearables and smartphone application.
The evaluation of the study participants was performed at baseline (1st visit), after 2 months (2nd visit) and after 8 months (3rd visit).

Experimental: Intervention group
Individuals participated in the 2-month outpatient aerobic exercise training program, which consisted of 40 training sessions on a cycle ergometer 5 times/week for 40 min.
Then during motivational consultation, individuals received recommendations for healthy lifestyle and home-based training.
After that, study subjects participated in the 6-month home-based aerobic exercise program using wearable device (heart rate monitor), which was connected to the smartphone via Bluetooth.
A special smartphone application enabled participants to keep their training heart rate during home-based exercises (or workouts).
