Brief Summary

Type 2 Diabetes (T2D) is associated with prolonged hospitalization and an increased risk of readmission. Moreover, sedentary behavior and poor glycemic control may contribute to disease severity and mortality. The inactivity during hospitalization is particularly concerning in T2D patients, due to the negative effect on glucose metabolism and secondary loss of skeletal muscle mass, which can further disrupt glucose regulation. However, there are no exercise guidelines for hospitalized T2D patients. To address this gap, a feasibility study will be conducted examining the effectiveness of incorporating resistance training into hospital care for T2D patients. For the feasibility study, 24 patients with T2D or prediabetes will be recruited from the Department of Infectious Diseases at Rigshospitalet and Hvidovre Hospital and randomized to 4 weeks of resistance training for 30 minutes per day or standard treatment. If the participants are discharged they will be offered online-training sessions. During the hospitalization a continuous glucose monitor will be applied and an accelerometer during the full intervention. At baseline, discharge and at follow-up, extensive testing will be performed.

Detailed Description

Patients will be invited to participate, preferably within the first 24 hours of admission, and randomized to either resistance-based bodyweight exercise or a control group. In total, 24 patients will be recruited, and distributed between the groups stratified for biological sex. At baseline, participants will have their medical history, social anamnesis, height, and weight assessed. At baseline a continuous glucose monitor will and accelerometer will be applied, to be worn until discharge and end of the intervention, respectively. Furthermore at baseline a multitude of questionnaires will be performed: International Physical Activity Questionnaire (IPAQ), Strength, Assistance in walking, Rise from a chair, Climb stairs, and Falls (SARC-F), Brief Illness Perception Questionnaire (BIPQ), 5-level EQ-5D version (EQ-5D-5L), WHO-5 Well-Being Index (WHO-5).

Intervention session A body-weight based resistance exercise program will be performed based on a booklet "Syg men sund og aktiv" Sick but healthy and active for 30 minutes per day. Described in more detail below.

Control session The control group will be placed in a seated position for 30 minutes corresponding to the time the intervention group is active.

Assessments before and after intervention/control sessions Before the sessions the EQ-5D-5L, the WHO-5 modified to a daily version, and an acute assessment of malaise, tiredness, nausea, dizziness, pain and breathlessness will be performed using numerical rating scales (NRS). After the session the NRS will be performed again.

Follow-up visit Two days after completion of the intervention, the participants will be invited for a follow-up visit at the Centre for Physical Activity Research, Rigshospitalet. This visit includes a qualitative interview, assessment of body composition, assessment of physical capabilities, ultrasound of the thigh, and blood samples. In case the patient is unable to attend the follow-up visit at the center, the daily operating manager will visit the patient at home. In this case, Ultrasound and muscle biopsy will not be performed. If the patient lives more than one hour away by car, the assessment will be performed online and will not include ultrasound, body composition and blood tests.

Study Groups

Exercise

The exercise intervention is a four-week intervention and will consist of body weight strength training. All training sessions during hospitalization will be supervised and will be performed individually for 30 min/day. If the patient is discharged within the four-week training period, the training will continue from home and will be online-based with a live video connection to an instructor. The training program will be the same. The intervention group will ideally exercise post-prandially (within 60 min following the meal) following either breakfast or lunch. Exercise intensity will be monitored throughout the training (with a heart rate monitor) and patients will estimate the rigorousness of the training using the rate of perceived exertion (RPE)-scale. If possible, the goal is for the patients to reach a minimum of 5, corresponding to moderate intensity, but preferably 7+ on the 0-10 RPE scale in each set. The aim is to complete the training sessions five out of seven days/week.

Group Type: EXPERIMENTAL

Exercise

Intervention Type: BEHAVIORAL

A body weight based resistance training.

Control

The Control group will be placed in a chair for 30 minutes, within 60 minutes following either breakfast or lunch daily during admission, depending on other workflows in the ward. This corresponds to the time spent on exercise by the intervention group. The control group will also be in daily contact with the instructor following discharge and will be asked the same daily questions and will be seated in a chair for 30 minutes as during hospitalization.

Group Type: NO_INTERVENTION

No interventions assigned to this group

Interventions
