Understanding Motivation Towards Exercise to Enhance Physical Activity on Prescription Adherence - Feasibility Study

The goal of this clinical trial is to explore feasibility and evaluate methods to investigate changes in physical activity, function and psychometrics in relation to an exercise intervention in physically inactive middle-aged men and women. The main questions it aims to answer are:

* Is the exercise intervention feasible regarding retention and user experience? * Is the evaluation methods on physical activity, function and psychometrics suitable for the present study? * Is there an intervention effect in physical activity, function and psychometrics at three and six month post baseline? * Can barriers and facilitators towards increased physical activity be identified in the two groups of the study?

All participants will first receive standard care for physically inactive patients, i.e. Physical activity on Prescription (PaP), followed by allocation to an exercise intervention (EI) group. The EI group will be offered an additional exercise intervention for 12 weeks consisting of 1-2 training sessions per week of a combination of aerobic and resistance training at a private fitness center.

Feasibility of the exercise intervention will be evaluated based on retention rates and user experience.

Additionally, researchers will assess physical activity, function and psychometrics in the EI group at three and six months to evaluate the suitability of the chosen methods and to get preliminary data on the intervention effect. Finally, interviews with the participants in the control and EI groups will be performed at the end of the study in order to explore barriers and facilitators towards increased physical activity in formally inactive patients.

Edit after registration of the study: Due to a lower number of recruited participants than expected (20 instead of the anticipated 30), the protocol was updated by removing the control group that would initially consist of 10 participants. The remaining 20 participants were all allocated to the exercise intervention group to assess feasibility of the intervention.

  • Physically inactive persons as defined as not meeting the current recommendations of at least 150 minutes of moderate to vigorous physical activity per week. This criterion is self-assessed by potential participants.
  • Age 40-60 years

Exclusion criteria

  • Hypertension grade III, i.e. systolic blood pressure above 180 mmHg and/or diastolic blood pressure over 110 mmHg.

Treatment and study plan

Exercise Intervention

Behavioral

The 6 month intervention consists of usual care (PaP) plus an initial 12 weeks of instructor led exercise (described below) followed by a 12 week period in where the participant will have to conduct their physical activity on their own.

Exercise intervention:

Participants are invited to a 12 week exercise intervention at a private fitness center after they have received their PaP. The exercise, including a variety of aerobic and resistance training, is performed in a group setting starting with one session per week for the first three weeks and then two sessions per week for week 4-12. A follow-up session is also included after 12 weeks in where a physiotherapist contact the participant and discuss how they will adhere to their Physical activity on prescription.

Primary outcomes

  1. Adherence to the exercise intervention

    Time frame: Documented continuously during the 12 week intervention period

    Number of completed training sessions in the exercise intervention group

  2. Retention rate

    Time frame: 3 months post baseline

    The proportion of participants starting the intervention that completes outcome assessment in either group

Secondary outcomes

  1. Time spent in moderate and vigorous physical activity

    Time frame: Baseline, 3 months and 6 months

    Objectively measured physical activity, measured with an accelerometer for 7 consecutive days. Raw data are then recalculated to minutes spent in different intensity zones and finally minutes in moderate and vigorous physical activity are calculated.

  2. Daily step-count

    Time frame: Baseline, 3 months and 6 months

    Objectively measured physical activity, measured with an accelerometer for 7 consecutive days is used to collect step-count which is presented as steps taken per day.

  3. Cardio-respiratory capacity

    Time frame: Baseline, 3 months and 6 months

    Ekblom-Bak cycle ergometer test will be used to assess cardio-respiratory fitness.

  4. Upper limb strength

    Time frame: Baseline, 3 months and 6 months

    Hand grip strength om the non dominant hand is measured with a hand dynamometer to the nearest kg. Three consecutive trials is performed in a seated position with the elbow held at a 90 degree angle and the highest value is recorded. A higher value indicate higher upper limb strength.

  5. Lower limb muscle strength

    Time frame: Baseline, 3 months and 6 months

    Five repetition sit to stand test. From a seated position, the participant is instructed to stand up and then sit down again for a total of five times. The total time of five repetition sit to stand cycles is then recorded in seconds with a stopwatch. A lower total time indicate higher lower limb muscle strength.

  6. Health related quality of life

    Time frame: Baseline, 3 months and 6 months

    RAND-36 health survey will be used (RAND is not an acronym but the name of a research corporation). The RAND-36 survey contains 36 questions belonging to eight health concepts that can be further categorized into two summary scores; physical and mental health. The answers from the survey is re-coded into points in where higher points indicate better perceived health. The points, ranging from 0 to 100, are then presented for the different concepts, the two summary scores and the overall score for the 36 questions.

  7. Self-reported exercise and physical activity

    Time frame: Baseline, 3 months and 6 months

    One question regarding exercise and one question regarding every day physical activity in a typical week. The question regarding exercise comprises 6 answer alternatives ranging from 0 min to more than 120 min per week. The question regarding every day physical activity comprises 7 answer alternatives raging from 0 min to more than 300 min per week. The questions are produced by the Swedish National Board of Health and Welfare.

  8. Motivational stages of self-determination for exercise

    Time frame: Baseline, 3 months and 6 months

    Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) will be used. The questionnaire contains 19 questions, belonging to one of the five categories Amotivation, External regulation, Introjected regulation, Identified regulation and Intrinsic regulation. The scale assesses where a person is on the continuum of self-determination in where higher, positive scores indicate greater relative autonomy; lower, negative scores indicate more controlled regulation.

  9. Confidence in one's own ability to exercise

    Time frame: Baseline, 3 months and 6 months

    The Swedish Exercise Self-Efficacy Scale (ESES-S) will be used. The questionnaire comprises 10 questions on exercise self-efficacy, each with four answer alternatives. The composite score ranges from 10 to 40 and a higher score indicate a higher precised self-efficacy towards exercise.

  10. Basic psychological needs connected to physical activity satisfaction

    Time frame: 3 months and 6 months

    The Basic Psychological Needs in Exercise Scale (BPNES) will be used. This questionnaire contains 12 questions related to one of three basic psychological needs; Autonomy, Competence and Relatedness in the exercise domain. Answers are given on a five point Likert scale and results are presented for the individual needs and as a collective, global need. The maximal score for each question is 5 and the minimal score is 1. Mean values for each need is presented together with a mean score of all 12 questions. A higher score indicate a higher need fulfillment.

Other outcomes

  1. Feasibility of the exercise intervention

    Time frame: 3 months

    Semi-structured qualitative individual interviews will be conducted with the exercise intervention group to explore the user experience of the participants

  2. Exploring barriers and facilitators towards physical activity

    Time frame: 6 months

    Semi-structured qualitative individual interviews will be conducted in both groups
