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).

Outcome Measures

Primary Outcomes (2)

• Change in objectively measured free-living physical activity

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

  Baseline, 4 weeks (mid), and 8 weeks (end)

• Change in adherence to muscle-strengthening guidelines

  Assessed by 7-day physical activity recall interview to see if participants engaged in muscle-strengthening activity at least 2 days per week.

  Baseline, 4 weeks (mid), and 8 weeks (end)

Secondary Outcomes (9)

• Change in sleep quality

  Baseline, 4 weeks (mid), and 8 weeks (end)

• Change in cardiorespiratory Fitness

  Baseline, 4 weeks (mid), and 8 weeks (end)

• Change in muscular fitness

  Baseline, 4 weeks (mid), and 8 weeks (end)

• Change in intrinsic Motivation

  Baseline, 4 weeks (mid), and 8 weeks (end)

• Change in social support

  Baseline, 4 weeks (mid), and 8 weeks (end)

Study Arms (2)

Physical activity intervention

EXPERIMENTAL

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

General health education control

NO INTERVENTION

Will receive twice-weekly, YouTube-delivered videos with general health education information for 8 weeks.

Interventions

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.

Eligibility Criteria

• Age: 18 Years - 35 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• 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.

You may not qualify if:

• 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.
