The aim of this study is to investigate the effects of physical activity program according to motivational interviewing based on the Transtheoretical Model on cardiovascular risk factors, physical activity level, physical activity behavior, and gait parameters in kidney transplant recipients.
The Transtheoretical Model evaluates readiness for behavior change. The Transtheoretical Model has been frequently used to determine how individuals adopt and maintain physical activity. In kidney transplant recipients (KTRs), increased physical activity level is associated with better graft function, and decreased physical activity is associated with increased cardiovascular and all-cause mortality. Therefore, it is important to evaluate the level of physical activity and to gain physical activity habits in KTRs. The aim of this study is to investigate the effects of physical activity program according to motivational interviewing based on the Transtheoretical Model on on cardiovascular risk factors, physical activity level, physical activity behavior, and gait parameters in KTRs.
28 KTRs who meet the inclusion criteria will be assigned to the physical activity program or control group by non-randomization method. In the physical activity group, a 12-weeks physical activity program will be applied by giving pedometer. 12 telephone sessions will be held once a week according to motivational interview techniques based on the Transtheoretical Model. Assessments will perform just before starting to study, at the end of 12 weeks (just after the physical activity program), and the end of 24 weeks. In the control group, information about physical activity will be given without applying the physical activity program. Control group's assessments will be performed when they are included in the study, at the end of 12 weeks and 24 weeks.
