Physical Activity Intervention Among College Students

Study Overview
=================
Brief Summary
-----------------
This project was to examine the effects of incorporating modern wearable technology into the credit-based Physical Activity Instructional Program for promoting habitual levels of physical activity among college students.

Detailed Description
-----------------
This project was a cluster randomized trial examining the effects of utilizing a wearable activity tracker in a credit-based Physical Activity Instructional Program on promoting habitual levels of physical activity (PA) in college students. The project was conducted in a large public university located in the mid-south region of the US. The university offers more than one hundred 1-credit hour PAIPs per academic semester. Considering the pilot nature of the study, the target PAIPs was limited to those meeting the following inclusion criteria: 1) PAIP with a size of 30 students that generally show an approximately equal gender distribution; and 2) PAIP that delivers the principles and practice of individually tailored habitual activity plans. The investigators randomly selected 14 eligible PAIPs and assigned them into intervention (k=7) and control (k=7) groups. The outcome measures of interests were the changes in objectively and subjectively measured physical activity over an academic semester.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Activity tracker group<br>Participants in intervention arm were provided with a small and lightweight activity tracker, Misfit Flash (Misfit Wearables Co., Burlingame, CA), that can be worn with a clasp or watch band. A handout detailing the step-by-step instructions for utilizing the activity tracker with Misfit App on their smartphone was provided. There was no intervention component mandated in the curriculum of intervention PAIP courses; rather, participants were continuously encouraged by the instructors to track their activity levels and use all the features in Misfit App on a daily basis as they learned health benefits of PA and as to how to develop individualized, life-long PA plan during the course of semester. | Behavioral: Activity tracker<br>* Misfit Flash (Misfit Wearables Co., Burlingame, CA) activity tracker<br>|
| No Intervention: Control group<br>Participants in control arm did not receive any additional instructions other than the scheduled class activities based on the standardized core-curriculum of PAIP | |
