About this study
Official title: Floor Sitting: An Exploration of Its Effects on Health and Sedentary Activity
The goal of this clinical trial is to evaluate the impact of different sitting environments on general well-being and movement patterns in healthy young adults aged 18-35. The main questions it aims to answer are:
Does floor sitting lead to increased movement and postural changes compared to chair sitting? Over a month-long period, how does sustained floor sitting influence overall well-being, posture, and movement habits?
Read more
Researchers will compare the effects of chair sitting and floor sitting in a controlled lab environment (Aim 1) and observe the longer-term effects of habitual floor sitting in participants natural environments (Aim 2) to see if consistent floor sitting promotes more dynamic movement and comfort.
Participants will:
Undergo two 30-minute experimental sitting sessions, one in a chair and the other on the floor, while engaging in typical desk activities (Aim 1).
Participate in a month-long study where they integrate an hour of floor sitting into their daily routines, recording their experiences and any changes in sitting habits through daily diaries and in-depth interview (Aim 2).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Chair Sitting (30 minutes)Behavioural
This intervention involves a single session of chair sitting for 30 minutes, where participants will sit in a standardized non-swivel chair and perform desk-based activities like computer use.
Floor Sitting (30 minutes)Behavioural
This intervention entails a single session of floor sitting for 30 minutes, with participants seated on a cushioned mat performing similar desk activities as in the chair sitting session.
Daily Floor Sitting Practice (1 month)Behavioural
Participants will be instructed to incorporate at least one hour of floor sitting into their daily routine for a duration of one month.
| Study group | Role | What they receive |
|---|---|---|
| Chair Sitting Experimental Arm | Experimental | Participants in this arm will undergo a 30-minute session of chair sitting in a non-swivel chair. Activities during this session include engaging in typical desk activities to simulate a natural office environment. Receives: Behavioral: Chair Sitting (30 minutes) |
| Floor Sitting Experimental Arm | Experimental | Participants in this arm will undergo a 30-minute session of floor sitting on a cushioned mat. They will engage in the same desk activities as the chair sitting arm to maintain consistency across conditions. Receives: Behavioral: Floor Sitting (30 minutes) |
| Extended Floor Sitting Intervention | Experimental | Participants in this arm will engage in daily floor sitting as part of their usual activities at home to assess the long-term effects of floor sitting on well-being and health. Receives: Behavioral: Daily Floor Sitting Practice (1 month) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in Movement Patterns via Accelerometry
Measurement of movement patterns using accelerometry to assess changes in physical activity levels and subtle movements, including frequency, intensity, and duration of movements during different sitting interventions (chair vs. floor sitting).
Measured: Recorded continuously during each 30-minute sitting session; analysis will compare aggregate data from the two sessions.
Variations in Sitting Posture Captured by Video Analysis
Utilization of video recordings to analyze and quantify postural changes during sitting sessions. This will involve evaluating variations in posture, such as shifts from upright to slouched positions, and identifying the frequency and diversity of postural transitions during each session.
Measured: Postural data will be collected throughout the two 30-minute experimental sitting sessions, with comparative analysis conducted post-intervention.
