YouTube-Delivered Physical Activity Intervention

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).

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

YouTube-delivered aerobic and muscle-strengthening physical activity intervention

Behavioral

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.

Primary outcomes

  1. Change in objectively measured free-living physical activity

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    7-day measurement using wrist-worn ActiGraph tri-axial accelerometer

  2. Change in adherence to muscle-strengthening guidelines

    Time frame: 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 outcomes

  1. Change in sleep quality

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    7-day measurement using wrist-worn ActiGraph tri-axial accelerometer

  2. Change in cardiorespiratory Fitness

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    YMCA 3-minute step test

  3. Change in muscular fitness

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    60 second pushups and sit-ups muscular endurance tests (maximal repetitions)

  4. Change in intrinsic Motivation

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    Psychosocial survey

  5. Change in social support

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    Psychosocial survey

  6. Change in perceived physical activity barriers

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    Psychosocial survey

  7. Change in body weight (kg)

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    Measured using stadiometer to the nearest 0.1 kg

  8. Height (cm

    Time frame: Baseline

    Measured using digital bodyweight scale to the nearest 0.1 cm

  9. Change in body fat percentage

    Time frame: Baseline, 4 weeks (mid), and 8 weeks (end)

    Measured using the digital weight scale used to assess body weight via bioelectrical impedance
