Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

As the primary objective, this study will evaluate the effectiveness, in terms of changes in physical strength, of a resistance training (RT) program consisting of brief bodyweight exercises (\<5 min/day) performed unsupervised every weekday for 12 weeks. Blood pressure, lipid profile, hemoglobin A1ca, habit strength and satisfaction with the program will also be assessed. Office workers and osteopathic medical students will serve as participants.They will be randomized (1:1) to the intervention group or to a waitlist control group that will refrain from RT for the initial 12 weeks. After the 12-week follow-up assessment, the intervention group will continue the program and the waitlist control group will start the program for 12 weeks, followed by a 24-week follow-up assessment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Regular resistance training (RT) provides significant health benefits. However, roughly 3 out of 4 US adults do not meet current US Physical Activity Guidelines regarding RT. Studies are needed that assess the effectiveness and feasibility of RT programs that are time-efficient and simple to perform.

This will be a randomized controlled study of a habit-based RT program consisting of one set each of push-ups, angled-rows, and bodyweight squats performed every weekday for 12 weeks. Forty to 60 office workers and osteopathic medical students, who currently do not engage in RT, will be recruited, assessed, and randomized (1:1) to an intervention group, which will perform the exercises as just described, or a waitlist control group, which will refrain from RT for 12 weeks. To promote consistent exercise performance, the intervention group will be trained in the Tiny Habits® Method (a systematic approach to adding new behaviors in one's daily routine) and receive digital coaching for the duration of the study.

After the 12-week follow-up assessment, the intervention group will continue the program for an additional 12 weeks, and the waitlist control group will start the program and continue for 12 weeks, including Tiny Habits training and digital coaching. A 24-week follow-up assessment will then be conducted.

The primary outcome of interest is the change from baseline to 12-weeks in physical strength from, as measured by the maximum number of composite repetitions (i.e., push-ups + angled-rows + bodyweight squats) performed under a standardized protocol. Secondary outcomes of interest include adherence to and satisfaction with the program, and change from baseline to 12- and 24-week follow-up in composite repetitions, habit strength, blood pressure, lipid panel, hemoglobin A1c, body mass index, anthropometry, body composition, and mid-thigh muscle thickness

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be randomized (1:1) to an intervention or waitlist control group. The intervention group will perform one set of the bodyweight exercises (i.e., push-ups, angled-rows, bodyweight squats), with training and coaching, unsupervised every weekday for 12 weeks. The waitlist control group will refrain from resistance training for the initial 12.

After a 12-week follow-up assessment, the intervention group will continue the RT program for an additional 12 weeks, and the waitlist control group will initiate the RT program and continue for 12 weeks. A 24-week follow-up assessment will then be conducted.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention Arm

Participants in this arm will be instructed to perform one set each of push-ups, angled-rows and bodyweight squats every weekday without supervision for a total of 24 weeks. They will receive the equipment necessary to perform the exercises as well as guidance on proper performance. They will also receive training in the Tiny Habits® Method at baseline and digital coaching for the duration of the study.

Group Type EXPERIMENTAL

Bodyweight exercises (push-ups, angled-rows, bodyweight squats) on weekdays

Intervention Type BEHAVIORAL

Participants will be instructed to perform one set each of push-ups, angled-rows, and bodyweight squats every weekday. They will be given the equipment and training necessary to properly perform the exercises. They will also be trained in the Tiny Habits® Method and receive digital coaching.

Waitlist Control Arm

Participants in the control arm will be instructed to refrain from resistance training for the initial 12 weeks of the study.

Note that, after the 12-week follow-up assessment (at which the primary outcome of composite reps will be assessed), this group will begin the RT program. They will receive the same equipment, training, and coaching as the intervention group, and they will continue the RT program for 12 weeks, followed by a 24-week assessment.
