About this study

Official title: Immersive Recreational Physical Exercise Program for Schoolchildren With Overweight or Obesity (PEESO)

Childhood overweight and obesity are major public health concerns associated with increased cardiometabolic risk and reduced quality of life. In Galicia (Spain), approximately one-third of schoolchildren aged 7-15 years are affected. Physical inactivity and sedentary behaviors contribute significantly to this condition.

The PEESO Project is a clinical trial designed to evaluate the effects of an immersive virtual reality-based physical exercise program delivered during school recess in children with overweight or obesity. The intervention uses head-mounted displays to promote moderate-to-vigorous intensity physical activity in an engaging environment.

Read the detailed description

Childhood overweight and obesity are major public health concerns worldwide and are associated with increased risk of cardiometabolic disease, musculoskeletal disorders, and reduced quality of life. In Galicia (Spain), approximately one-third of schoolchildren aged 7-15 years present overweight or obesity. Physical inactivity and excessive sedentary behaviors, particularly screen time, contribute significantly to this condition.

The PEESO Project is a clinical trial designed to evaluate the effects of an immersive recreational physical exercise program delivered during school recess in children diagnosed with overweight or obesity. The intervention uses immersive virtual reality (IVR) technology through head-mounted displays to create an interactive and engaging environment that promotes moderate-to-vigorous intensity physical activity.

Immersive virtual reality may enhance exercise adherence and enjoyment by increasing motivation and reducing perceived exertion through distraction. Although active video games (exergames) have demonstrated potential to increase daily physical activity and reduce body mass index (BMI), most previous studies have focused on non-immersive systems and adult populations.

The primary objective of this study is to determine the effect of a moderate-to-vigorous intensity immersive virtual exercise program on body composition in schoolchildren with overweight or obesity. Secondary objectives include assessing its impact on quality of life and other health-related outcomes. The intervention is implemented during academic recess periods to ensure feasibility and integration within the school setting.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RVI_Experimental_Immersive Virtual Reality Exergame ProgramBehavioural

    Participants assigned to the experimental group will perform immersive virtual reality exercise sessions THREE (3) TIMES A WEEK during school breaks. The intervention lasts 24 weeks, following a one-week adaptation period to the head-mounted devices (HMDs) and exercise video games. Exercise routines will be personalized to each participant's characteristics using a "Weight Loss" mode and will include three training categories: Full Body (6 weeks), Strength (9 weeks), and Boxing (9 weeks). The exercise load will be programmed individually through the exercise video game platform based on each participant's progress and performance. The sessions are designed to achieve a moderate to vigorous level of physical activity.

  • RVI_ControGroup_Immersive Virtual Reality Exergame ProgramBehavioural

    Participants assigned to the control group will perform immersive virtual reality exercise sessions ONE TIMES (1) A WEEK during school breaks. The intervention lasts 24 weeks, following a one-week adaptation period to the head-mounted devices (HMDs) and exercise video games. Exercise routines will be personalized to each participant's characteristics using a "Weight Loss" mode and will include three training categories: Full Body ( 6 weeks), Strength (9 weeks), and Boxing (9 weeks). The exercise load will be programmed individually through the exercise video game platform based on each participant's progress and performance.
