Immersive Physical Activity Program for Overweight Schoolchildren (PEESO)

26 giugno 2026 aggiornato da: José M. Cancela, University of Vigo

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.

Descrizione dettagliata

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.

Intervento / Trattamento
Sperimentale: RVI_Experimental_Immersive Virtual Reality Exergame Program
The PEESO intervention is an immersive recreational physical exercise program designed for schoolchildren with overweight or obesity. The intervention is delivered during school recess periods using Head-Mounted Display (HMD)-based immersive virtual reality exergames. The program aims to provide moderate-to-vigorous intensity physical activity through personalized exercise sessions in a motivating and interactive environment.
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.
Comparatore placebo: RVI_ControGroup_Immersive Virtual Reality Exergame Program
The PEESO intervention in the control group will be the same as in the experimental group: a recreational and immersive physical exercise program designed for overweight or obese schoolchildren. It is conducted during school recess using immersive virtual reality exercise video games with virtual reality headsets (HMDs). The program aims to provide moderate-to-vigorous physical activity through personalized exercise sessions in a motivating and interactive environment.
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. The sessions are designed to achieve a moderate to vigorous level of physical activity.

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Assessment body composition
Lasso di tempo: 24 weeks

Description: Body composition was assessed using the Tanita MC-780 bioelectrical impedance analyzer. Measured variables included fat mass (FM), fat-free mass (FFM), muscle mass (MM), total body water (TBW), and segmental body composition of the trunk and limbs.

Unit of Measurement:

Fat Mass (FM): kg

Fat-Free Mass (FFM): kg

Muscle Mass (MM): kg

Total Body Water (TBW): kg

Segmental Body Composition: kg

Interpretation: Higher FFM, MM, and TBW indicate better physical fitness. Lower FM indicates better body composition.

Lasso di tempo: 24 weeks

Description:

Health-related quality of life will be assessed using the KINDL Questionnaire, a validated instrument that evaluates children's and adolescents' well-being across multiple domains, including physical well-being, emotional well-being, self-esteem, social relationships, and school functioning. Scores are calculated according to the instrument scoring manual and transformed to a scale from 0 to 100.
