An interventional study of YouTube-delivered aerobic and muscle-strengthening physical activity intervention in Healthy, sponsored by University of Minnesota. Completed at 1 site in United States. Open to participants aged 18 Years to 35 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2022-04-06.

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).
2,646 studies on the registry are indexed under Motor Activity; 1,205 are open to participants now.
This study's enrollment of 64 is close to the median of 60 across 2,309 interventional studies indexed under Motor Activity.

Exclusion Criteria:
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
Will receive twice-weekly, YouTube-delivered videos with general health education information for 8 weeks.
Participants in the intervention group will receive two YouTube-delivered videos each week, for 8 weeks.

Ran from Dec 2020 to primary completion in Mar 2021, 3 months.
Of 1,726 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 47. This study's 3 months is below that.
Counting every sponsor, half of 1,738 studies reached it within 23 months; a quarter within 9 and three quarters within 47.
