What was measured

This physical performance test of flexibility is done as follows: \- Participant stands upright and reach one hand over the shoulder and the other up the middle of the back, attempting to touch or overlap middle fingers (both sides are tried - right over left, then left over right). Outcome measure is the distance between the closest fingers (most flexible side is recorded) Scoring: 0 inches → fingertips just touch Negative (-) → fingers do not touch (gap distance) Positive (+) → fingers overlap (amount of overlap)

Analysis population: The number of participants analyzed differ between pre- intervention baseline and 12-month post-intervention due to withdrawal by participant or loss to follow up.

Groups in this outcome

Project 1: Diet-Exercise

Participants will receive and participate in web-based sessions that focus on diet for 6 months, followed by exercise for another 6 months. Participants will be encouraged to track their diet and weight for the first 6 months and to log their data in the intervention website, during the second 6 months they will be asked to log their physical activity data (minutes and step counts). Tailored feedback and goal recommendations will be provided through the website. Participants will also receive access to resources for relevant behavioral topics. All participants will be invited to participate in the secret Facebook group for the project (though participation is optional).

Project 2: Exercise-Diet

Participants will receive and participate in web-based sessions that focus on diet for 6 months, followed by exercise for another 6 months. Participants will be encouraged to track their diet and weight for the first 6 months and to log their data in the intervention website, during the second 6 months they will be asked to log their physical activity data (minutes and step counts). Tailored feedback and goal recommendations will be provided through the website. Participants will also receive access to resources for relevant behavioral topics. All participants will be invited to participate in the secret Facebook group for the project (though participation is optional).

Project 3: Combined Diet and Exercise

Participants will receive the diet and exercise content simultaneously in combined web-based sessions. Participants will receive and participate in web-based sessions that focus on diet and exercise for 12 months. Participants will be encouraged to track their diet, weight and physical activity data (minutes and step counts). Tailored feedback and goal recommendations will be provided through the website. Participants will also receive access to resources for relevant behavioral topics. All participants will be invited to participate in the secret Facebook group for the project (though participation is optional).
