YouTube-Delivered Physical Activity Intervention
Study Details
Study Description
Brief Summary
This study will be an 8-week randomized controlled trial examining the effects of a YouTube-delivered aerobic and muscle strengthening physical activity intervention on university students' physical activity, fitness, sleep quality, and psychosocial health outcomes. Participants will be randomized into 1 of 2 groups: (1) intervention group (receive twice-weekly YouTube videos [1 aerobic workout video; 1 muscle-strengthening workout video] for 8 weeks); or (2) control group (receive twice-weekly YouTube videos with general health information [no physical activity-related information or workouts] for 8 weeks). Baseline (0 weeks), mid-point (4 weeks), and post-test (8 weeks) testing will take place and the following outcome measures will be assessed at these time points: participants' free-living (7-day) objectively-measured physical activity and sleep quality data will be collected; anthropometric measures (height, weight, percent body fat); cardiorespiratory and muscular fitness; and psychosocial assessments (perceived physical activity barriers and social support).

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Physical activity intervention Will receive twice-weekly, YouTube-delivered aerobic and muscle-strengthening physical activity videos for 8 weeks. |
Behavioral: YouTube-delivered aerobic and muscle-strengthening physical activity intervention
Participants in the intervention group will receive two YouTube-delivered videos each week, for 8 weeks. In detail, on Monday, participants will receive an aerobic-based physical activity video with information and a workout to complete and on Thursdays, the participants will receive a video with muscle-strengthening physical activity information and a workout to complete.

| No Intervention: General health education control Will receive twice-weekly, YouTube-delivered videos with general health education information for 8 weeks. |
Outcome Measures
Primary Outcome Measures
- Change in objectively measured free-living physical activity [Baseline, 4 weeks (mid), and 8 weeks (end)]
7-day measurement using wrist-worn ActiGraph tri-axial accelerometer
- Change in adherence to muscle-strengthening guidelines [Baseline, 4 weeks (mid), and 8 weeks (end)]
Assessed by 7-day physical activity recall interview to see if participants engaged in muscle-strengthening activity at least 2 days per week.
Secondary Outcome Measures
- Change in sleep quality [Baseline, 4 weeks (mid), and 8 weeks (end)]
7-day measurement using wrist-worn ActiGraph tri-axial accelerometer
- Change in cardiorespiratory Fitness [Baseline, 4 weeks (mid), and 8 weeks (end)]
YMCA 3-minute step test
- Change in muscular fitness [Baseline, 4 weeks (mid), and 8 weeks (end)]
60 second pushups and sit-ups muscular endurance tests (maximal repetitions)
- Change in intrinsic Motivation [Baseline, 4 weeks (mid), and 8 weeks (end)]
Psychosocial survey
- Change in social support [Baseline, 4 weeks (mid), and 8 weeks (end)]
Psychosocial survey
- Change in perceived physical activity barriers [Baseline, 4 weeks (mid), and 8 weeks (end)]
Psychosocial survey
- Change in body weight (kg) [Baseline, 4 weeks (mid), and 8 weeks (end)]
Measured using stadiometer to the nearest 0.1 kg
- Height (cm [Baseline]
Measured using digital bodyweight scale to the nearest 0.1 cm
- Change in body fat percentage [Baseline, 4 weeks (mid), and 8 weeks (end)]
Measured using the digital weight scale used to assess body weight via bioelectrical impedance
Eligibility Criteria
Criteria
Inclusion Criteria:
- 18-35 years of age; able to participate in aerobic and muscle-strengthening exercise; healthy (i.e., no diseases or clinical/mental health conditions which will prevent physical activity participation); does not meet minimum physical activity guidelines criteria for aerobic (≥ 150 minutes per week of moderate-to-vigorous intensity physical activity) and muscle-strengthening (≥ 2 days per week; 8-10 exercises for all major muscle groups) physical activity at time of enrollment; willing to be randomized to the intervention or control group.
Exclusion Criteria:
- less than 18 years old or greater than 35 years old; physical or mental health contradictions which do not allow participants to participate in physical activity; exceed minimum aerobic or muscle-strengthening physical activity guideline recommendations; unwilling to be randomized to either intervention or control group.
