Exercise Approaches and Physical Activity Level in Inactive Adults

Effects of Different Exercise Approaches on Physical Activity Level and Health Outcomes in Inactive Adults

This randomized, controlled, single-blind study aims to compare the effects of different exercise approaches on physical activity level and health-related outcomes in inactive adults. Thirty inactive individuals aged 18-35 years will be randomly assigned to supervised face-to-face group exercise, mobile application-based exercise, or video-based home exercise. Exercise programs will be performed three days per week for eight weeks and will include aerobic, strengthening, and flexibility exercises.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Face-to-Face Supervised Exercise	Other: Face-to-Face Supervised Exercise; Participants will perform supervised face-to-face group exercise sessions three days per week for eight weeks under the guidance of a physiotherapist. Each session will include aerobic, strengthening, and flexibility exercises.
Experimental: Mobile App-Based Exercise	Device: Mobile App-Based Exercise; Participants will perform exercise sessions using the Nike+ Training Club mobile application three days per week for eight weeks. The program will include aerobic, strengthening, and flexibility exercises delivered through asynchronous video content.
Experimental: Home-Based Video Exercise	Other: Home-Based Video Exercise; Participants will perform video-based home exercise sessions using the "Walk at Home: Leslie" program three days per week for eight weeks. The program will include aerobic, strengthening, and flexibility exercises.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Total Physical Activity Level	Physical activity will be assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). Total physical activity will be calculated as metabolic equivalent (MET)-minutes per week based on walking, moderate-intensity, and vigorous-intensity activities performed during the last 7 days. Higher values indicate higher levels of physical activity.	From baseline to the end of the intervention at 8 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Daily Step Count	Daily step count will be measured using a wearable activity tracker. The average number of steps per day will be recorded. Higher values indicate higher levels of physical activity. Unit of Measure is steps per day.	From baseline to the end of the intervention at 8 weeks
Active Time	Active time will be assessed using a wearable activity tracker. The average duration of active movement per day will be recorded. Higher values indicate greater daily physical activity duration. Unit of measure is minutes per day.	From baseline to the end of the intervention at 8 weeks
Energy Expenditure	Daily energy expenditure related to physical activity will be measured using a wearable activity tracker. Higher values indicate greater caloric expenditure through physical activity. Unit of Measure is kilocalories per day.	From baseline to the end of the intervention at 8 weeks
Distance Covered	Distance covered during daily activities will be recorded using a wearable activity tracker. Higher values indicate greater daily movement. Unit of Measure is kilometers per day.	From baseline to the end of the intervention at 8 weeks
Aerobic Capacity	Aerobic capacity will be assessed using the 6-Minute Walk Test. The outcome measure will be the total distance walked in meters during the six-minute test period.	From baseline to the end of the intervention at 8 weeks
Lower Extremity Muscle Strength	Lower extremity muscle strength will be assessed using the 1-Minute Sit-to-Stand Test. The outcome will be the total number of correctly performed sit-to-stand repetitions completed within one minute.	From baseline to the end of the intervention at 8 weeks
Health Releated Quality of Life	Health-related quality of life will be assessed using the Short Form-36 Health Survey (SF-36). The SF-36 consists of eight domains assessing physical and mental health. Each domain is scored on a 0-100 scale, with 0 indicating the worst health status and 100 indicating the best health status. Higher scores represent better perceived health-related quality of life.	From baseline to the end of the intervention at 8 weeks
Participant Satisfaction and Perceived Change	Participant satisfaction and perceived change will be assessed using the Global Rating of Change (GRC) scale. Participants will rate their perceived overall change and satisfaction with the intervention compared to baseline.	At the end of the intervention (8 weeks)
