Digital Follow-up of Aerobic Interval Training in Outpatients With Mental Disorders

Peak oxygen uptake after the training period subtracted Peak oxygen uptake at baseline. Using the The Vyntus ONE with a mixing chamber. It is a powerful tool for comprehensive cardiopulmonary testing, providing accurate and reliable data to help clinicians make informed decisions.

Physical activity level for 1-2 weeks (triaxial accelerometer, wGT3X-BT, ActiGraph LLC, USA)

Medical record data, Norwegian patient register (NPR) and the Norwegian Registry for Primary Health Care (NRPHC) - which together cover all governmental-funded health care, and occupational status (NAV)

Helseplattformen: Number of times logging in, time spent in the program. Usaga data from the exercise app such as number of exercise sessions logged, and exercise intensity will be collected from Myworkout AS. Medications, diagnosis, number of hospitalizations

• Sit-to-stand test: 30-second sit-to-stand test. Number of full stands in 30 seconds.
• Unipedal stance test: Single leg stance. Measured in seconds.
• Stair performance: Stair test. Participants are instructed to ascend and descend 18 steps 3 consecutive times. Performance measured in seconds.

Follow-up through HelsaMI. Training session diary of exercise performed from the Myworkout GO app.

Walking economy (oxygen uptake at a standard workload) after the training period subtracted walking economy at baseline. It is tested at a submaximal workload and calculated as a reduction in whole body pulmonary V̇O2 or energy expenditure (Kcal∙-min) accomplished during walking.

The BREQ-2 is a 19-item questionnaire that measures different types of motivation for exercise based on self-determination theory. It includes factors such as intrinsic motivation, identified regulation, introjected regulation, external regulation, and amotivation

The eHEALS is an 8-item scale designed to assess consumers' perceived skills at finding, evaluating, and applying electronic health information. It measures knowledge, comfort, and perceived skills in using eHealth resources

The MEX scale is a 30-item measure that assesses mental health-related barriers and benefits to exercise. It includes two subscales: one for barriers and one for benefits, each with 15 items. It is designed to understand how mental health symptoms impact exercise engagement.

The SUS is a 10-item Likert scale that provides a global measure of system usability. It assesses the effectiveness, efficiency, and satisfaction of a system from the user's perspective

Client Satisfaction Questionnaire-8 (CSQ-8): The CSQ-8 is an 8-item questionnaire designed to measure client satisfaction with health and human services. It provides a global measure of satisfaction, with items rated on a 4-point scale from "1" (low satisfaction) to "4" (high satisfaction).

Patient Activation Measure for Mental Health (PAM-13, MH): The PAM-13 is a 13-item questionnaire that assesses a patient's knowledge, skills, and confidence in managing their own health. It is specifically adapted for mental health contexts to measure the level of patient activation

Quality of life: SF-36® Health Survey (SF-36): Designed to measure overall health status and quality of life. It covers eight domains: physical functioning, role limitations due to physical health, role limitations due to emotional problems, energy/fatigue, emotional well-being, social functioning, pain, and general health

EuroQol five dimensions questionnaire (EQ-5D-3L): A standardized instrument used to measure health-related quality of life. It includes five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, each with three levels of severity. It also includes a visual analogue scale (VAS) for self-rated health.

Body weight, measured in kilograms (kg). Height, measure in centimeters (cm). Body mass index (BMI) calculated by dividing the weight in kilograms by the square of the height in meters. Waist Circumference, Waist circumference is the measurement taken around the abdomen at the level of the belly button. It is used to assess abdominal fat.

The force of blood pushing against the walls of the arteries. It is measured using two numbers: systolic pressure (when the heart beats) and diastolic pressure (when the heart rests between beats).

Glucose: Measures the level of sugar in the blood. It is used to diagnose and monitor diabetes. Triglycerides: Measures the amount of fat in the blood. High levels can increase the risk of heart disease. HbA1C: Measures the average blood sugar levels over the past 2-3 months. It is used to diagnose and monitor diabetes. Apolipoprotein A1: The main protein component of HDL (good cholesterol). It helps in the transport of cholesterol from tissues to the liver.

Apolipoprotein B: The main protein component of LDL (bad cholesterol). It is involved in the transport of cholesterol to tissues and is a marker for cardiovascular risk. Cholesterol: High-Density Lipoprotein (HDL): Known as "good" cholesterol, it helps remove bad cholesterol from the bloodstream.

Low-Density Lipoprotein (LDL): Known as "bad" cholesterol, high levels can lead to plaque buildup in arteries and increase the risk of heart disease. Total Cholesterol: The sum of HDL, LDL, and other lipid components in the blood
