The aim of this study was to find the disparities in fitness between pupils aged 10 to 12 who had a normal body mass index and those who were obese. This quantitative descriptive study sought to identify the variations in fitness, particularly in cardiorespiratory fitness, among students aged 10 to 12. Cardiorespiratory fitness was assessed indirectly using a Volume Oxygen Maximum (VO2max) prediction algorithm. The Shapiro-Wilk test is used in the normalcy test. Thirty students, split into two groups, made up the sample. Fifteen students in the first group had a normal body mass index, while fifteen students in the second group were obese. The results of the test indicated that the data had an anomalous distribution, with p=0.012 (p<0.05). The Mann-Whitney test is used in hypothesis testing. With a result of p=0.000 (p<0.05), the U test revealed a difference in fitness between 10–12-year-old kids who were obese and those with a normal body mass index. This study demonstrated that students aged 10 to 12 who were obese and those with a normal body mass index differed in terms of fitness.

The studys findings indicate a significant difference in physical fitness levels between elementary school students aged 10-12 with normal BMI and those with obesity.Obese children exhibit lower VO₂max values, signifying reduced aerobic capacity compared to their peers with normal weight.These results underscore the importance of developing school and family-based interventions to promote increased physical activity and establish healthy eating patterns from an early age.

Penelitian lebih lanjut perlu dilakukan untuk menginvestigasi pengaruh intervensi gaya hidup yang terintegrasi, seperti program olahraga yang disesuaikan dan edukasi gizi keluarga, terhadap peningkatan kebugaran kardiovaskular pada anak-anak obesitas. Selain itu, studi komparatif yang melibatkan berbagai kelompok usia dan latar belakang sosioekonomi dapat memberikan pemahaman yang lebih mendalam mengenai faktor-faktor yang berkontribusi terhadap disparitas kebugaran terkait obesitas. Terakhir, penelitian kualitatif yang mengeksplorasi persepsi dan motivasi anak-anak obesitas dalam berpartisipasi dalam aktivitas fisik dapat membantu dalam merancang intervensi yang lebih efektif dan berkelanjutan, dengan mempertimbangkan aspek psikologis dan sosial yang memengaruhi perilaku mereka. Penelitian-penelitian ini diharapkan dapat memberikan landasan yang kuat bagi pengembangan strategi pencegahan dan penanganan obesitas yang komprehensif dan berpusat pada anak.
