Background/objectivesThe aim of the study was to examine the effects of exercise training through telerehabilitation applied during COVID-19 isolation period on overweight and obese individuals on physical fitness and quality of life.Subjects/methodsIn our study, 41 participants between the ages of 18–65 years and whose BMI values were 25 kg/m2 and above were randomly divided into two groups as telerehabilitation group (n: 21) and control group (n: 20). Exercise training applied to the telerehabilitation group with remote live connection included warm-up exercises, trunk stabilization exercises and breathing exercises under the supervision of a physiotherapist for 6 weeks, 3 days in a week. The control group was only informed about the importance of exercise for one session and evaluated at baseline and after 6 weeks. The physical fitness levels of individuals was assessed by Senior Fitness Test protocol and quality of life by Short Form-36.ResultsAs a result of the study, statistically significant improvements were obtained in all parameters of physical fitness, quality of life in the telerehabilitation group (p < 0.05). In the difference values of the two groups, all parameters of physical fitness and quality of life were observed that there were statistically significant differences in favor of telerehabilitation group (p < 0.05).ConclusionsAs a result, it was found that exercise training applied through telerehabilitation during the COVID-19 pandemic process was an effective, safe and viable approach in overweight and obese individuals. In the future, studies investigating the long-term effectiveness of telerehabilitation in this population are needed.
