Active Video Game Using Virtual Reality Influence Cognitive Ability in Sedentary Female University Students: Randomized Clinical Trial

The experiment was conducted at the Human Biomechanics Laboratory of the College of Applied Medical Sciences of Prince Sattam bin Abdulaziz University between February 2024 and May 2024. During the briefing, all questions were answered to ensure that participants understood the experiment and its objectives. On the day of the experiment, demographic information was collected, including age, height, weight, body mass index (BMI), and preferred leg. An Eye-Level Weight Beam scale (Detecto, Webb City, MO, USA) was used to determine the weight and height of the subjects. To identify the preferred leg, participants were observed ascending stairs or kicking a ball.

Participants were recruited and assigned to one of two groups, either the control group or the VR group. Participants were required to attend one experimental session in a random order using Microsoft Excel's (Microsoft Corp., Redmond, WA, USA) random list function. The VR group was required to play a 20-minute game of Beat Saber VR, while the control group was asked to sit quietly for 20 minutes without any activities assigned. This study used an accelerometer from ActivPal (PAL Technologies Ltd, Glasgow, UK) to capture the PA levels of the VR group throughout the VR game. Following previously published validation studies and manufacturer recommendations, a strip of Tegaderm (3M, St. Paul, MN) was attached to the preferred leg's front thigh.
